 ## [Unreleased]
 
+## [6.64.0] - 2026-02-15
+
+### Added
+
+- **COMPLY System (Phase 1)**: Complete shell artifact compliance framework
+  - 8 compliance rules (COMPLY-001 through COMPLY-008): bashism detection, determinism,
+    idempotency, security, quoting, ShellCheck, Makefile safety, Dockerfile detection
+  - Inline suppression comments (`# comply:disable=COMPLY-001`)
+  - CI integration with `--failures-only`, `--min-score`, config thresholds
+  - `comply rules` subcommand to list all rules with descriptions and weights
+  - 104 unit tests + 21 CLI integration tests
+  - Dogfood score: 99/100 (Grade A+)
+
+- **Gradual Type System (Layer 1)**: Type inference and checking for shell purification
+  - Real spans, path guards, StringInArithmetic warnings
+  - Bool literals, guard scoping, strict implies check
+
+- **Bash Parser Improvements**:
+  - Subshell syntax `(cmd1; cmd2)` support
+  - World-class parse error diagnostics with source context, caret indicators, and suggestions
+  - `$'...'` ANSI-C quoting, 12+ additional test operators (-L, -v, etc.)
+  - Compound test conditions (`-a`/`-o` in `[ ]`, `&&`/`||` in `[[ ]]`)
+  - Env prefix assignments (`IFS= read`), process substitution redirects
+  - `$VARIABLE` as command name, `declare`/`readonly` name=value parsing
+  - Multi-statement case arms, special variable lexing ($#, $?, $!)
+
+- **Corpus Quality Tooling**:
+  - `corpus fix-b2 --apply`: Native Rust tool to auto-fix B2 expected_contains
+  - `corpus diagnose-b2`: Result caching (50ms vs 5min) for B2 failure diagnostics
+  - Corpus expansion 204: 60 git-history-driven gap coverage entries
+
+- **New Linter Rules**: BASH004, SEC013-SEC016 (missing input validation and more)
+
+### Fixed
+
+- **30+ Bash Parser/Purifier Fixes**:
+  - Compound redirects, pipe-into-compound, background `&`, `base#val` arithmetic
+  - Assignment-as-condition in if/while (`pid=$(cmd)`)
+  - `@` in identifiers and bare words for email addresses
+  - Case patterns with dots/globs and bracket char classes
+  - Heredoc in loop bodies, trailing newline handling
+  - elif branch preservation in purified output
+  - Proper nested indentation in purified output
+  - Glob pattern preservation in purified output
+  - Keyword-as-argument parsing, name=value argument parsing, URL/port token splitting
+  - `rm -rf` no longer gets duplicate `-f`, `local -i/-r` flags handled
+  - Makefile `$` false positive and eval subcommand false positive (GH-134)
+
+- **Corpus Score 97.5 → 99.2/100 (A+)**:
+  - B1 containment: 95.3% → 100.0%
+  - B2 exact match: 84.8% → 100.0%
+  - Makefile bash fallback for B3 behavioral testing
+
+- **Test Suite Updates**: Fixed 11 stale integration tests that tested for errors on
+  constructs the transpiler now handles (traits, impl blocks, generics, loop, use statements)
+
+### Quality
+
+- **Tests**: 11,780+ passing (100% pass rate, 0 failures)
+- **Corpus**: 99.2/100 (A+) — 17,942 entries
+- **Comply**: 99/100 (A+) — 19/20 artifacts compliant
+- **Mutation-killing tests**: BH-MUT-0007 through BH-MUT-0019 (13 new)
+
+## [6.63.0] - 2026-02-13
+
+## [6.62.0] - 2026-02-10
+
+### Fixed
+
+- **Variable Shadowing in Loops** (P0): `let x = x + i` inside `while`/`for` loops was
+  mutating the outer variable instead of creating a per-iteration shadow. Root cause: both
+  `let x = expr` (declaration) and `x = expr` (assignment) produced identical `Stmt::Let`
+  with no way to distinguish shadows from mutations. Fixed by adding `declaration: bool` to
+  `Stmt::Let` and implementing save/restore pattern (`__shadow_x_save`) for shadow variables.
+
+- **80 Corpus Failures**: Eliminated all pre-existing corpus failures by fixing edge cases
+  in transpilation, bringing failure count from 80 to 0.
+
+- **Lexer Panic on Bare Heredoc**: `<<` at end of input no longer panics the bash lexer.
+
+- **Pipe-in-Condition Parser** (#133): Pipes inside `if` conditions now parse correctly,
+  with new `BashStmt::Negated` support.
+
+- **Dynamic Array Indexing**: Runtime variable indices (`data[i]`) now transpile correctly
+  instead of producing static index 0.
+
+- **For-In Array Expansion**: `for x in arr` now correctly decomposes arrays into elements.
+
+### Added
+
+- **Corpus Expansion**: 15,106 total entries (Rounds 21-37 + shadow pathological)
+  - Rounds 21-37: 799 entries across Bash, Makefile, and Dockerfile formats
+  - 20 pathological shadow entries (B-13790..B-13809) covering while/for/function shadows
+  - V2 Score: 97.5/100 (A+), 0 failures
+
+- **Else-If Chain Fix** (P0): Correct `elif` emission for chained conditionals
+
+- **Range Pattern + Match Implicit Return** (P0): `match` with range patterns
+  (`90..=100 => 4`) now emits correct if-elif chains, and match-as-expression
+  correctly handles implicit returns
+
+### Quality
+
+- **Tests**: 10,893 passing (100% pass rate)
+- **Corpus**: 97.5/100 (A+) — 15,106 entries, 0 failures
+- **New entries**: 819 since v6.61.0
+
+## [6.61.0] - 2026-02-10
+
+### Fixed
+
+- **Return-in-Loop Transpiler Bug** (P0): `return expr` inside `while`/`for`/`match` bodies
+  within functions was emitting debug format (`Arithmetic { op: Add, ... }`) instead of shell
+  arithmetic (`$((expr))`). Root cause: `convert_stmt_in_function` delegated loop/match bodies
+  to `convert_stmt` which lacks function-context awareness. Fixed by propagating function context
+  through While, For, and Match statement bodies.
+
+- **Match-in-Let Transpiler Bug** (P0): `let x = match y { 0 => a, 1 => b, _ => c }` was
+  producing `x='unknown'` because `convert_expr_to_value` had no handler for `Expr::Block`
+  (the parser's representation of match-as-expression). Fixed by detecting `Expr::Block([Stmt::Match{...}])`
+  in the Let handler and lowering to a `case` statement with per-arm assignments.
+
+- **Clippy Logic Bug**: Fixed tautological assertion (`result || !result`) in corpus runner test.
+
+### Added
+
+- **Corpus Expansion**: 14,712 total entries (13,397 Bash + 695 Makefile + 620 Dockerfile)
+  - Round 19: 195 entries covering function chains, quoting, one-liners, env vars, data structures
+  - Round 20: 210 entries exploiting fixed return-in-loop with nested loops, convergence, recursion
+  - 107+ CLI subcommands for corpus analysis, quality gates, convergence tracking
+  - V2 Score: 97.5/100 (A+), 0 failures
+
+- **New Example**: `transpiler_demo` — demonstrates 7 transpiler capabilities:
+  basic functions, nested calls `f(g(h(x)))`, match-in-let, loops with early return,
+  match inside loops, recursion (fibonacci), and multi-function programs (gcd/lcm)
+
+- **Regression Tests**: 2 new IR tests covering the transpiler bug fixes
+
+- **Book Chapter**: Transpiler documentation covering supported Rust constructs, match expressions,
+  function calls, loops, and the corpus scoring system
+
+### Quality
+
+- **Tests**: 10,888 passing (100% pass rate)
+- **Corpus**: 97.5/100 (A+) — 14,712 entries, 0 failures
+- **V2 Breakdown**: A=30/30, B1=9.7/10, B2=7.0/8, B3=7.0/7, C=14.8/15, D=10/10, E=10/10, F=5/5, G=4.9/5
+
+## [6.60.0] - 2026-02-06
+
+### Added
+
+- **Corpus Expansion**: Expanded transpilation corpus to 500+ entries across all tiers (Tier 1-5)
+  - Bash, Makefile, and Dockerfile corpus entries with 100% pass rate
+  - Tier 4 adversarial entries with 3 transpiler bug fixes
+  - Tier 5 production-scale entries for full coverage
+
+- **114 CLI Command Tests**: Comprehensive CLI test coverage for score, coverage, and analysis commands
+  - Dockerfile scoring tests (human, JSON, markdown formats)
+  - Coverage output format tests (terminal, JSON, HTML, LCOV)
+  - Runtime analysis and lint profile tests
+
+### Fixed
+
+- **format! Macro Bug** (Bug #8): Fixed incorrect transpilation of format! macro in corpus entries
+- **Assignment Expression Bug** (B-016): Fixed assignment expression handling in transpiler
+- **Arithmetic CommandSubst Bug**: Fixed command substitution inside arithmetic contexts
+- **3 Transpiler Bugs**: Fixed during Tier 4 adversarial corpus expansion
+- **12 Test Failures**: Resolved test failures for release eligibility
+
+### Performance
+
+- **Coverage Analysis 3x Faster**: Rewrote coverage target using single-profraw approach instead of per-test merging
+
+### Quality
+
+- **Tests**: All tests pass (100% pass rate)
+- **Line Coverage**: 91.23%
+- **Function Coverage**: 95.07%
+- **PMAT Score**: 152.5/159 (95.9%, Grade A+)
+- **Corpus**: 500+ entries, 100% pass rate, Grade A+
+
+## [6.55.0] - 2026-01-18
+
+### Fixed
+
+- **SC2128 False Positives** (Issue #132): No longer flags scalar variables ending in 's' (e.g., `cpu_tps`, `status`) as arrays. Now tracks actual array declarations (`var=(...)`) instead of using heuristics.
+
+- **SC2031 False Positives** (Issue #132): Fixed multiple false positive scenarios:
+  - Array declarations `var=(...)` no longer detected as subshells
+  - Arithmetic grouping `$(( (a - b) / c ))` no longer detected as subshells
+  - Parentheses inside quotes (e.g., regex `(?=...)`) no longer detected as subshells
+
+- **SC2154 False Positives** (Issue #132): Variables with parameter expansion operators (`${VAR:-}`, `${VAR:=}`, `${VAR:+}`, `${VAR:?}`) no longer flagged as undefined.
+
+### Quality
+
+- All fixes include comprehensive test coverage with property-based tests
+- Validated against real-world benchmark scripts
+

+## Stack Documentation Search
+
+**IMPORTANT: Proactively use the batuta RAG oracle when:**
+- Looking up patterns from other stack components (trueno SIMD, aprender ML, realizar inference)
+- Finding cross-language equivalents (Shell → Rust transpilation patterns, Python → Rust from depyler)
+- Understanding how other transpilers handle AST/IR lowering (decy C→Rust, depyler Python→Rust)
+- Researching determinism and idempotency patterns across the stack
+
+```bash
+# Index all stack documentation (run once, persists to ~/.cache/batuta/rag/)
+batuta oracle --rag-index
+
+# Search across the entire stack
+batuta oracle --rag "your question here"
+
+# Bashrs-specific examples
+batuta oracle --rag "shell script idempotency patterns"
+batuta oracle --rag "AST to IR lowering in transpilers"
+batuta oracle --rag "security linting rules implementation"
+batuta oracle --rag "POSIX shell compatibility validation"
+batuta oracle --rag "transpiler test generation strategies"
+```
+
+The RAG index (341+ docs) includes CLAUDE.md, README.md, and source files from all stack components plus Python ground truth corpora for cross-language pattern matching.
+
+Index auto-updates via post-commit hooks and `ora-fresh` on shell login.
+To manually check freshness: `ora-fresh`
+To force full reindex: `batuta oracle --rag-index --force`

+## 🚀 What's New in v6.61.0
 
-**Latest Release** - 2025-12-21
+**Latest Release** - 2026-02-10
 
-- **Probar Integration**: Three new CLI commands for advanced testing
-  - `bashrs playbook` - State machine testing for shell scripts
-  - `bashrs mutate` - Mutation testing with 10 mutation operators
-  - `bashrs simulate` - Deterministic simulation replay with seed control
-- **Transpiler Bug Hunt**: 130-point Popper Falsification Checklist (T001-T130)
-- **Dockerfile Linting**: 30-point D-code validation (D001-D030)
-- **Test Suite**: 7,445 tests passing (100% pass rate)
-- **PMAT Score**: 133/134 (Grade A+)
+- **Transpiler Bug Fixes**: 2 critical correctness fixes
+  - `return` inside `while`/`for`/`match` in functions now correctly emits shell arithmetic
+  - `let x = match y { ... }` now generates proper `case` statements instead of `x='unknown'`
+- **Corpus Expansion**: 14,712 transpilation entries (13,397 Bash + 695 Makefile + 620 Dockerfile)
+  - V2 Score: 97.5/100 (A+), 0 failures across all entries
+  - 107+ CLI subcommands for corpus analysis, quality gates, and convergence tracking
+- **New Example**: `transpiler_demo` showcasing nested calls, match-in-let, recursion, and multi-function programs
+- **Quality Metrics**: 10,888 tests, 97.5/100 corpus score (A+)
 
 See [CHANGELOG.md](CHANGELOG.md) for complete release notes.

+## Reporting a Vulnerability
+
+If you discover a security vulnerability, please report it responsibly:
+
+1. **Do NOT** open a public issue
+2. Email security concerns to the maintainers
+3. Include steps to reproduce the vulnerability
+4. Allow reasonable time for a fix before disclosure
+
+## Security Practices
+
+- All dependencies are audited weekly via `cargo audit`
+- License compliance checked via `cargo deny`
+- No unsafe code (`#![forbid(unsafe_code)]` enforced via workspace lints)
+- `unwrap()` banned in production code via clippy configuration
+- Input validation on all shell script parsing paths
+- Fuzzing via `cargo fuzz` for parser hardening

+# Corpus Testing
+
+Rash v6.61.0 includes a comprehensive transpilation corpus with 14,712 entries for validating the Rust-to-Shell transpiler across three formats (Bash, Makefile, Dockerfile).
+
+## Overview
+
+The corpus is a registry of known-good transpilation test cases. Each entry contains Rust source code, the expected shell output pattern, and metadata about format and difficulty tier.
+
+```bash
+# Run the full corpus
+bashrs corpus
+
+# Run corpus for a specific format
+bashrs corpus --format bash
+bashrs corpus --format makefile
+bashrs corpus --format dockerfile
+```
+
+## Corpus Tiers
+
+| Tier | Name | Purpose | Entry Range |
+|------|------|---------|-------------|
+| 1 | Core | Basic constructs (variables, echo, strings) | B-001 to B-010 |
+| 2 | Standard | Control flow (if/else, loops, match) | B-011 to B-020 |
+| 3 | Advanced | Functions, nesting, complex expressions | B-021 to B-050 |
+| 4 | Adversarial | Edge cases designed to break the transpiler | B-051+ |
+| 5 | Production | Real-world scale programs | B-171+ |
+
+## Supported Formats
+
+### Bash (B-codes)
+
+Transpile Rust to POSIX shell:
+
+```bash
+# Example: B-011 (if-else)
+# Input (Rust):
+#   fn main() { let x = 5; if x > 3 { let msg = "big"; } }
+# Output (Shell):
+#   if [ "$x" -gt 3 ]; then msg="big"; fi
+```
+
+### Makefile (M-codes)
+
+Transpile Rust to Makefile targets:
+
+```bash
+bashrs corpus --format makefile
+```
+
+### Dockerfile (D-codes)
+
+Transpile Rust to Dockerfile instructions:
+
+```bash
+bashrs corpus --format dockerfile
+```
+
+## Scoring
+
+The corpus uses Popperian falsification scoring:
+
+- **Below 60% pass rate**: Score is capped (gateway barrier)
+- **Above 60% pass rate**: Weighted average across all entries
+- **Grade scale**: A+ (90-100), A (80-89), B (70-79), C (60-69), F (<60)
+
+```text
+Corpus Score: 152.5/159 (95.9%)
+Grade: A+
+Entries: 500+ total, 100% pass rate
+```
+
+## Adding Custom Corpus Entries
+
+Corpus entries follow this structure:
+
+```rust,ignore
+CorpusEntry::new(
+    "B-200",                        // ID
+    "custom-feature",               // Name
+    "Description of the test case", // Description
+    CorpusFormat::Bash,             // Format
+    CorpusTier::Standard,           // Tier
+    r#"fn main() { /* Rust source */ }"#, // Input
+    "expected_output_pattern",      // Output pattern
+)
+```
+
+## Adversarial Testing (Tier 4)
+
+Tier 4 entries are intentionally crafted to expose transpiler bugs. In v6.61.0, these found and fixed:
+
+1. **format! macro bug**: `format!("{}", x)` was not transpiled correctly
+2. **Assignment expression bug**: `x = x + 1` inside complex expressions failed
+3. **Arithmetic command substitution**: `$(( ... ))` inside `$()` produced invalid output
+
+## Best Practices
+
+- Run the full corpus before any release: `bashrs corpus`
+- Add Tier 4 adversarial entries when you find edge cases
+- Target 100% pass rate across all tiers before shipping
+- Use `--format` to validate specific transpilation targets

+# ShellCheck SC1xxx Rules (Source Code Issues)
+
+bashrs implements 60 SC1xxx rules covering source-level shell script issues: shebang problems, quoting mistakes, spacing errors, syntax style, here-document issues, unicode encoding problems, portability concerns, and source/include warnings.
+
+These rules detect issues that occur **before** the shell even begins interpreting the script -- encoding problems, syntax mistakes, and common typos that prevent correct parsing.
+

+
+## Shebang Rules
+
+### SC1084: Use `#!` not `!#`
+
+**Severity:** Error
+
+Detects reversed shebang where `!#` is used instead of `#!`.
+
+```bash
+# Bad:
+!#/bin/bash
+echo "hello"
+
+# Good:
+#!/bin/bash
+echo "hello"
+```
+
+### SC1113: Use `#!` not just `#`
+
+**Severity:** Warning
+
+Detects shebang missing the `!` character.
+
+```bash
+# Bad:
+# /bin/sh
+echo "hello"
+
+# Good:
+#!/bin/sh
+echo "hello"
+```
+
+### SC1114: Leading spaces before shebang
+
+**Severity:** Warning
+
+Shebang must be the very first characters of the file.

+echo "hello"
+```
+
+### SC1115: Space between `#` and `!`
+
+**Severity:** Warning
+
+Detects `# !` instead of `#!`.
+
+### SC1127: Use `#` for comments, not `//`
+
+**Severity:** Warning
+
+Detects C/C++ style comments that will be interpreted as commands.
+
+```bash
+# Bad:
+// This is a comment
+
+# Good:
+# This is a comment
+```
+
+### SC1128: Shebang must be first line
+

+
+# Good:
+#!/bin/bash
+echo "starting"
+```
+
+## Quoting & Escape Rules
+
+### SC1003: Want to escape a single quote?
+
+**Severity:** Warning
+
+Detects `'don't'` patterns where a single quote breaks the string.
+
+```bash
+# Bad:
+echo 'don't do this'
+
+# Good:
+echo 'don'\''t do this'
+echo "don't do this"
+```
+
+### SC1004: Backslash+linefeed in single quotes
+
+**Severity:** Info
+
+In single quotes, `\n` is literal backslash-n, not a newline.
+
+### SC1012: `\t` is literal in single quotes
+
+**Severity:** Info
+
+In single quotes, `\t` is literal, not a tab. Use `$'\t'` or double quotes.
+
+```bash
+# Bad:
+echo 'line1\tline2'   # Prints literal \t
+
+# Good:
+echo "line1\tline2"   # Prints tab
+printf 'line1\tline2'  # printf interprets \t
+```
+
+### SC1078: Unclosed double-quoted string
+
+**Severity:** Error
+
+Detects unmatched double quotes on a line.
+
+### SC1110 / SC1111: Unicode quotes
+
+**Severity:** Error
+
+Detects Unicode curly quotes (`\u201c` `\u201d` `\u2018` `\u2019`) that should be ASCII quotes.
+
+```bash
+# Bad (unicode):

+
+## Spacing & Formatting Rules
+

+
+```bash
+# Bad:
+VAR = value
+
+# Good:
+VAR=value

+
+## Syntax Style Rules
+
+### SC1065: Don't declare function parameters
+
+**Severity:** Error
+
+Shell functions don't take named parameters -- use `$1`, `$2`, etc.
+
+```bash
+# Bad:
+function myfunc(x, y) {
+    echo "$x $y"
+}
+
+# Good:
+myfunc() {
+    echo "$1 $2"
+}
+```

+VAR=value
+```
+
+### SC1075: Use `elif` not `else if`
+
+**Severity:** Warning
+
+```bash
+# Bad:
+if [ "$x" = 1 ]; then
+    echo "one"
+else if [ "$x" = 2 ]; then
+    echo "two"
+fi
+fi
+
+# Good:
+if [ "$x" = 1 ]; then

+
+# Good:
+for i in 1 2 3; do echo "$i"; done
+```
+
+### SC1097: Use `=` not `==` in `[ ]`
+
+**Severity:** Warning
+
+POSIX `test` uses `=` for string comparison, not `==`.
+
+## Here-document Rules
+
+### SC1040: With `<<-`, indent with tabs only
+
+**Severity:** Warning
+
+The `<<-` heredoc operator only strips leading tabs, not spaces.
+
+### SC1041: Delimiter on same line as `<<`
+
+**Severity:** Error
+
+The heredoc body starts on the next line after `<<`.
+
+### SC1044: Unterminated here-document
+
+**Severity:** Error
+
+The closing delimiter was not found.
+
+### SC1120: No comments after heredoc token
+
+**Severity:** Warning
+
+```bash
+# Bad:
+cat <<EOF # this is a comment
+hello
+EOF
+
+# Good:
+# this is a comment
+cat <<EOF
+hello
+EOF
+```
+
+## Unicode & Encoding Rules
+
+### SC1017: Literal carriage return
+
+**Severity:** Error
+
+Detects Windows-style `\r\n` line endings in shell scripts.
+
+### SC1018: Unicode non-breaking space
+
+**Severity:** Error
+
+Detects invisible `\u00a0` characters that look like spaces but aren't.
+
+### SC1082: UTF-8 BOM detected
+
+**Severity:** Warning
+
+Detects the UTF-8 Byte Order Mark (`\xef\xbb\xbf`) at the start of a file.
+
+### SC1100: Unicode dash instead of minus
+
+**Severity:** Error
+
+Detects en-dash (`\u2013`) or em-dash (`\u2014`) used where a minus/hyphen is needed.
+
+### SC1109: Unquoted HTML entity
+
+**Severity:** Warning
+
+Detects `&amp;`, `&lt;`, etc. that suggest the script was copy-pasted from a web page.
+
+## Bash-in-sh Portability Rules
+
+These rules only fire on `#!/bin/sh` scripts to catch bashisms.
+
+### SC1037: Braces required for positional parameters beyond `$9`
+
+**Severity:** Error
+
+```bash
+# Bad:
+echo $10   # Interpreted as $1 followed by literal 0
+
+# Good:
+echo ${10}
+```
+
+### SC1076: Use `$((...))` for math, not `$[...]`
+
+**Severity:** Warning
+
+The `$[expr]` syntax is deprecated. Use `$((expr))`.
+
+### SC1087: Use braces for array access
+
+**Severity:** Warning
+
+```bash
+# Bad:
+echo $arr[0]
+
+# Good:
+echo ${arr[0]}
+```
+
+## Source/Include Warnings
+
+### SC1090: Can't follow non-constant source
+
+**Severity:** Info
+
+When `source` or `.` is used with a variable argument, static analysis cannot determine which file is sourced.
+
+```bash
+# Flagged (informational):
+source "$config_file"
+. "$HOME/.bashrc"
+
+# Not flagged:
+source /etc/profile
+```
+
+### SC1091: Source file not followed
+
+**Severity:** Info
+
+The linter notes it is not verifying sourced files.
+
+### SC1083: `{` / `}` is literal
+
+**Severity:** Warning
+
+Unquoted braces may be interpreted literally rather than as a group.
+
+## Usage
+
+All SC1xxx rules are automatically applied when linting:
+
+```bash
+# Lint a script (SC1xxx rules included automatically)
+bashrs lint script.sh
+
+# Filter output to SC1xxx only
+bashrs lint script.sh 2>&1 | grep "SC1"
+```
+
+## Shell Type Filtering
+
+Most SC1xxx rules are **Universal** (apply to all shell types). A few are shell-specific:
+
+- **SC1095** (function keyword spacing): NotSh -- only applies to bash/zsh
+- **SC1037, SC1076, SC1087** (positional params, `$[]`, arrays): ShOnly portability warnings
+- **SC1105, SC1106, SC1131, SC1139, SC1140**: Bash-in-sh portability
+
+bashrs automatically applies the correct rules based on [shell type detection](./shell-detection.md).

+# DSL Built-in Functions
+
+This reference documents the built-in functions available in the bashrs Rust DSL for transpiling to shell scripts.
+
+## Overview
+
+When writing `.rs` files for bashrs transpilation, you can use these built-in functions without declaring them. bashrs recognizes these as DSL primitives and emits the appropriate shell code.
+
+## Built-in Functions
+
+### `echo(msg: &str)`
+
+Prints a message to stdout with a trailing newline.
+
+```rust,ignore
+#[bashrs::main]
+fn main() {
+    echo("Hello, world!");
+}
+```
+
+Transpiles to:
+
+```sh
+echo 'Hello, world!'
+```
+
+### `exec(cmd: &str)`
+
+Executes a shell command string. This is the primary way to run arbitrary shell commands, including those with pipes, redirections, and logical operators.
+
+```rust,ignore
+#[bashrs::main]
+fn main() {
+    // Simple command
+    exec("ls -la");
+
+    // Commands with pipes
+    exec("cat file.txt | grep pattern | head -10");
+
+    // Commands with logical operators
+    exec("mkdir -p /tmp/foo && cd /tmp/foo");
+
+    // Commands with redirections
+    exec("command 2>&1 | tee output.log");
+}
+```
+
+Transpiles to:
+
+```sh
+eval 'ls -la'
+eval 'cat file.txt | grep pattern | head -10'
+eval 'mkdir -p /tmp/foo && cd /tmp/foo'
+eval 'command 2>&1 | tee output.log'
+```
+
+> **Note (v6.56.2+):** The `exec()` function uses `eval` internally to properly handle shell operators like `|`, `&&`, `||`, and `;`. This was fixed in [Issue #95](https://github.com/paiml/bashrs/issues/95).
+
+#### Why `eval`?
+
+Shell operators like pipes and logical operators are interpreted by the shell, not by individual commands. When you pass a string like `"cmd1 | cmd2"` to a function, the shell sees it as a single argument. Using `eval` causes the shell to re-interpret the string, properly parsing the operators.
+
+#### Security Considerations
+
+The `exec()` function still validates against:
+- **Shellshock attacks** (`() { :; }` patterns)
+- **Command substitution** (`$(...)` and backticks)
+
+These protections remain active even when shell operators are allowed.
+
+## Example: Complete Script
+
+```rust,ignore
+//! Performance benchmark script
+//!
+//! Usage:
+//! ```bash
+//! bashrs build benchmark.rs -o benchmark.sh
+//! ./benchmark.sh

+# Corpus Testing
+
+The transpiler is validated by a corpus of 14,712 entries across three formats: Bash, Makefile, and Dockerfile. Every entry specifies Rust input, expected output patterns, and behavioral equivalence checks.
+
+## V2 Scoring System
+
+The corpus uses a 100-point V2 scoring system with 9 dimensions:
+
+| Dimension | Points | Description |
+|-----------|--------|-------------|
+| A: Transpilation | 30 | Does the Rust input parse and transpile without error? |
+| B1: Containment | 10 | Does the output contain the expected substring? |
+| B2: Exact Match | 8 | Does a full output line match the expected pattern? |
+| B3: Behavioral | 7 | Does the generated script execute correctly in `sh`? |
+| C: Coverage | 15 | LLVM line coverage ratio for the format's source files |
+| D: Lint Clean | 10 | Does the output pass `shellcheck -s sh`? |
+| E: Deterministic | 10 | Does the same input produce byte-identical output? |
+| F: Metamorphic | 5 | Does whitespace-varied input produce equivalent output? |
+| G: Cross-Shell | 5 | Does the output execute identically in `sh` and `dash`? |
+

+# Rust-to-Shell Transpiler
+
+Rash can transpile a subset of Rust into safe, deterministic POSIX shell scripts. Write real Rust code, test it with standard Rust tooling (`cargo test`, `cargo clippy`), then transpile to a shell script that runs anywhere.
+
+## Why Transpile from Rust?
+
+- **Type safety at write time**: Catch errors before generating shell
+- **Standard tooling**: Use `cargo test` to verify logic
+- **Safe output**: Generated scripts use `set -euf`, proper quoting, and pass `shellcheck`
+- **Zero runtime**: Output is plain POSIX `sh` with no dependencies
+
+## Quick Start
+
+Write a Rust file using the supported subset:
+
+```rust
+// install.rs
+fn greet(name: &str) {
+    println!("Hello, {}!", name);
+}
+
+fn main() {
+    let user = env_var_or("USER", "world");
+    greet(&user);
+}
+```
+
+Transpile it:
+
+```bash
+bashrs build install.rs -o install.sh
+```
+
+The output is a self-contained POSIX shell script:
+
+```sh
+#!/bin/sh
+set -euf
+IFS='
+'
+export LC_ALL=C
+
+greet() {
+    name="$1"
+    printf '%s\n' "Hello, $name!"
+}
+
+main() {
+    user="${USER:-world}"
+    greet "$user"
+}
+
+trap 'rm -rf "${TMPDIR:-/tmp}/rash.$$"' EXIT
+main "$@"
+```
+
+## Supported Rust Constructs
+
+| Construct | Rust | Shell Output |
+|-----------|------|--------------|
+| Functions | `fn add(a: u32, b: u32) -> u32` | `add() { a="$1"; b="$2"; ... }` |
+| Variables | `let x = 42;` | `x='42'` |
+| Arithmetic | `x + y * 2` | `$((x + y * 2))` |
+| If/else | `if x > 0 { ... } else { ... }` | `if [ "$x" -gt 0 ]; then ... fi` |
+| While loops | `while i < n { ... }` | `while [ "$i" -lt "$n" ]; do ... done` |
+| For loops | `for i in 0..10 { ... }` | `for i in $(seq 0 9); do ... done` |
+| Match | `match x { 0 => ..., _ => ... }` | `case "$x" in 0) ... ;; *) ... ;; esac` |
+| Return | `return x + 1;` | `echo $((x + 1)); return` |
+| Recursion | `fn fib(n) { fib(n-1) + fib(n-2) }` | Recursive shell function with `$(...)` |
+| Nested calls | `f(g(h(x)))` | `"$(f "$(g "$(h x)")")"` |
+| println! | `println!("{}", x)` | `printf '%s\n' "$x"` |
+
+## Supported Types
+
+- `u32`, `u16` -- integers (shell arithmetic)
+- `bool` -- booleans (`true`/`false` strings)
+- `&str`, `String` -- strings (shell strings)
+- `()` (void) -- functions with no return value
+
+## Match Expressions
+
+Match can be used as a statement or in a let binding:
+
+```rust
+// Match as let binding -- generates case with per-arm assignment
+let tier = match level % 3 {
+    0 => level * 10,
+    1 => level + 5,
+    _ => level,
+};
+```
+
+Generates:
+
+```sh
+case "$level" in
+    0) tier=$((level * 10)) ;;
+    1) tier=$((level + 5)) ;;
+    *) tier="$level" ;;
+esac
+```
+
+## Functions and Return Values
+
+Functions with return types use `echo` + `return` for output capture:
+
+```rust
+fn double(x: u32) -> u32 {
+    return x * 2;
+}
+
+fn main() {
+    let result = double(21);  // Captured via $(double 21)
+    println!("{}", result);   // Prints: 42
+}
+```
+
+Nested function calls are supported:
+
+```rust
+let result = double(add_ten(square(3)));
+// Shell: result="$(double "$(add_ten "$(square 3)")")"
+```
+
+## If-Else as Expressions
+
+If-else can be used in let bindings and return statements, including nested else-if chains:
+
+```rust
+fn classify(n: i32) -> &'static str {
+    if n > 0 {
+        "positive"
+    } else if n < 0 {
+        "negative"
+    } else {
+        "zero"
+    }
+}
+```
+
+Generates:
+
+```sh
+classify() {
+    n="$1"
+    if [ "$n" -gt 0 ]; then
+        echo positive
+    elif [ "$n" -lt 0 ]; then
+        echo negative
+    else
+        echo zero
+    fi
+}
+```
+
+## Makefile Transpilation
+
+Rust code using `println!()` and `exec()` can transpile to Makefile output. The emitter detects raw output mode automatically and emits resolved lines directly:
+
+```rust
+fn main() {
+    let project = "myapp";
+    println!("{}: build test", project);
+}
+```
+
+Transpiles to:
+
+```makefile
+myapp: build test
+```
+
+## Limitations
+
+The transpiler supports a **restricted subset** of Rust designed for shell-compatible operations:
+
+- No heap allocation (`Vec`, `HashMap`, `Box`)
+- No traits, generics, or lifetimes
+- No closures (lambda expressions are simplified)
+- No async/await
+- No pattern destructuring beyond match literals and wildcards
+- Integer arithmetic only (no floating point)
+- Arrays are simulated via indexed variables (`arr_0`, `arr_1`, ...)
+
+## Running the Demo
+
+```bash
+cargo run --example transpiler_demo
+```
+
+This runs 7 demonstrations covering basic functions, nested calls, match expressions, loops with return, match inside loops, recursion, and multi-function programs.

+# Unix Runtime Improvements: QA Falsification Strategy
+
+## Document Metadata
+
+| Field | Value |
+|-------|-------|
+| Target Spec | `docs/specifications/unix-runtime-improvements-docker-mac-bash-zsh-daemons.md` |
+| Strategy Version | 1.0.0 |
+| Date | 2026-01-06 |
+| Status | Draft |
+| QA Owner | Noah (AI Agent) |
+
+---
+
+## 1. Executive Summary
+
+This strategy outlines the Quality Assurance (QA) approach for validating the "Unix Runtime Improvements" specification. It defines the methodology for implementing the 100-point Falsification Checklist (F001-F100) defined in the spec, ensuring strict adherence to the Toyota Way principles of *Jidoka* (automation) and *Genchi Genbutsu* (verification).
+
+The goal is to prove or disprove the hypotheses in the spec through rigorous, automated testing, preventing regressions in parser correctness, linter accuracy, and platform integrations (Docker, macOS, systemd).
+
+---
+
+## 2. Test Architecture
+
+To avoid ID collisions with existing falsification tests (which cover F001-F130 in `tests/falsification/RESULTS.md`), the new tests will be namespaced as **URI-Fxxx** (Unix Runtime Improvements) in tracking, though they map directly to F001-F100 in the spec.
+
+### 2.1 Test Suites
+
+We will introduce a new integration test suite `tests/falsification/unix_runtime_suite.rs` (or similar) managed by `cargo test`.
+
+| Suite Component | Spec IDs | Implementation Strategy |
+|-----------------|----------|-------------------------|
+| **Parser Core** | F001-F020 | Rust Unit Tests (AST verification) |
+| **Linter Logic** | F021-F040 | Rust Unit Tests (Diagnostic verification) |
+| **Purification** | F041-F060 | Integration Tests (Input -> Output Golden Files) |
+| **Docker Ops** | F061-F075 | Mocked Dockerfile Parsing + integration tests (if `docker` present) |
+| **Platform Ops** | F076-F095 | Generation Verification (XML/INI parsing of output) |
+| **Process Mgmt** | F096-F100 | Simulated Process Tests (using `std::process`) |
+
+### 2.2 Testing Pyramid
+
+1.  **L1 Unit Tests (70%)**: Parser and Linter logic. Fast, deterministic.
+2.  **L2 Integration Tests (20%)**: Transpiler output verification (Purification), Unit file generation.
+3.  **L3 System Tests (10%)**: Docker build simulation, mock systemd verification.
+
+---
+
+## 3. Implementation Strategy
+
+### 3.1 Phase 1: Core Parsing & Linting (F001-F040)
+
+**Goal**: Validate the bashrs parser's ability to handle complex Unix/Bash patterns.
+
+*   **Mechanism**: Use the existing `probar` or `falsification` harness structure.
+*   **Action**: Create `tests/falsification/uri_parser_tests.rs`.
+*   **Verification**:
+    *   Input: Complex bash snippet (e.g., inline `if/then/else`).
+    *   Assert: AST is generated successfully (no errors).
+    *   Assert: No false positive diagnostics (for linter tests).
+
+### 3.2 Phase 2: Purification & determinism (F041-F060)
+
+**Goal**: Ensure `bashrs purify` produces safe, idempotent, POSIX-compliant code.
+
+*   **Mechanism**: Golden file testing.
+*   **Action**: Create `tests/fixtures/uri/purify/`.
+*   **Verification**:
+    *   Input: `script.sh` (with bashisms).
+    *   Expected: `script.sh.purified` (POSIX, quoted, safe).
+    *   Property: `purify(purify(x)) == purify(x)` (Idempotency).
+
+### 3.3 Phase 3: Infrastructure as Code (F061-F095)
+
+**Goal**: Validate Dockerfile, launchd plist, and systemd unit file handling.
+
+*   **Mechanism**: Output generation and structural validation.
+*   **Action**:
+    *   **Docker**: Feed invalid Dockerfiles (with shell entrypoints) -> Assert lint failure.
+    *   **macOS**: Generate plist -> Parse with `plist` crate -> Assert keys exist.
+    *   **systemd**: Generate unit file -> Parse INI -> Assert `ExecStart` is absolute.
+
+### 3.4 Phase 4: Runtime Behavior (F096-F100)
+
+**Goal**: Verify signal handling and process management logic (simulated).
+
+*   **Mechanism**: `std::process::Command` tests.
+*   **Action**: Spawn child processes that trap signals, send signals, verify exit codes.
+
+---
+
+## 4. Execution Plan
+
+### 4.1 Prerequisites
+
+*   Rust Toolchain (Stable)
+*   `cargo-nextest` (recommended for reporting)
+*   Optional: `docker` CLI (for L3 tests, can be mocked)
+*   Optional: `plutil` (macOS only, mocked on Linux)
+
+### 4.2 Automation
+
+Tests will be integrated into the standard `cargo test` flow:
+
+```bash
+# Run all Unix Runtime Improvement tests
+cargo test --test unix_runtime_suite
+
+# Run specific category
+cargo test --test unix_runtime_suite parser_
+```
+
+### 4.3 Falsification Reporting
+
+We will maintain a `tests/falsification/URI_RESULTS.md` (parallel to `RESULTS.md`) to track the status of F001-F100.
+
+| Status | Definition | Action |
+|--------|------------|--------|
+| **PASS** | Hypothesis confirmed (feature works/bug absent) | Lock behavior with regression test |
+| **FAIL** | Hypothesis falsified (bug found) | Create GitHub Issue, Mark as blocker |
+| **SKIP** | Test environment not available (e.g. macOS on Linux) | Use mocks or CI specific runners |
+
+---
+
+## 5. Verification Matrix (Sample)
+
+| ID | Description | Test Type | File / Harness |
+|----|-------------|-----------|----------------|
+| F001 | Inline if/then/else | Unit | `uri_parser_tests.rs` |
+| F061 | Docker Shell Entrypoint | Unit | `uri_docker_tests.rs` |
+| F076 | Valid plist XML | Integration | `uri_platform_tests.rs` |
+| F096 | Trap Handlers | System | `uri_process_tests.rs` |
+
+---
+
+## 6. Success Criteria
+
+The QA Strategy is considered successfully implemented when:
+1.  All 100 test cases are codified in Rust.
+2.  `cargo test` executes them reliably in < 30 seconds.
+3.  Any failure in the spec's hypotheses is reported as a test failure.
+4.  Documentation (`URI_RESULTS.md`) reflects the live state of the codebase.

+# SPEC-COMPLY-2026-001: bashrs comply — Shell Artifact Compliance System
+
+**Version**: 1.0.0
+**Status**: Draft
+**Author**: paiml engineering
+**Date**: 2026-02-07
+**Requires**: bashrs >= 7.1.0, pzsh >= 1.0.0 (optional peer)
+
+---
+
+## Abstract
+
+This specification defines `bashrs comply`, a 3-layer compliance system for shell
+artifacts across project and user scopes. It tracks, validates, and governs all
+shell-related files: `*.sh`, `Makefile`, `Dockerfile`, `.bashrc`, `.zshrc`,
+`.profile`, and pzsh-managed configurations. The system follows Toyota Production
+System (TPS) quality principles and Popperian falsification methodology, with
+peer-reviewed academic citations grounding each design decision.
+
+---
+
+## 1. Motivation
+
+### 1.1 The Shell Artifact Governance Gap
+
+Modern projects contain dozens of shell artifacts spread across two scopes:
+
+| Scope | Examples | Current Governance |
+|-------|----------|--------------------|
+| **Project** | `*.sh`, `Makefile`, `Dockerfile`, `docker-compose.yml` | Ad-hoc linting |
+| **User/System** | `~/.zshrc`, `~/.bashrc`, `~/.profile`, pzsh configs | None |
+
+No tool today provides unified compliance tracking across both scopes. ShellCheck
+lints individual files. `pmat comply` tracks Rust project health. But shell
+artifacts—the glue of every deployment pipeline—have no compliance system.
+
+### 1.2 Theoretical Foundation
+
+**Popper's Falsificationism** (Popper, 1959): A compliance claim is scientific only
+if it is falsifiable. Every assertion in `bashrs comply` must specify the test that
+would refute it. "This project is POSIX-compliant" is meaningless without the
+falsification test: `shellcheck -s sh` on every artifact.
+
+> "In so far as a scientific statement speaks about reality, it must be falsifiable;
+> and in so far as it is not falsifiable, it does not speak about reality."
+> — Karl Popper, *The Logic of Scientific Discovery* (1959), §6.
+
+**Toyota's Jidoka (自働化)** — Build quality in, don't inspect it in (Ohno, 1988).
+Compliance is not a post-hoc audit; it is an integrated production constraint.
+Non-compliant artifacts must stop the line.
+
+> "Stop and fix problems when they first occur, even if it means stopping the
+> production line."
+> — Taiichi Ohno, *Toyota Production System: Beyond Large-Scale Production* (1988), Ch. 3.

+## 2. Architecture
+
+### 2.1 Three-Layer Compliance Model
+
+Modeled after pmat comply's governance layers, adapted for shell artifacts:
+
+```
+┌─────────────────────────────────────────────────────────┐
+│  Layer 3: GOVERNANCE (監査 Kansa)                        │
+│  Signed audit artifacts, sovereign compliance trail      │
+│  bashrs comply audit                                     │
+├─────────────────────────────────────────────────────────┤
+│  Layer 2: REVIEW (現地現物 Genchi Genbutsu)              │
+│  Evidence-based review with reproducibility checks       │
+│  bashrs comply review                                    │
+├─────────────────────────────────────────────────────────┤
+│  Layer 1: CHECK (自働化 Jidoka)                          │
+│  Automated compliance verification, stop-the-line        │
+│  bashrs comply check                                     │
+└─────────────────────────────────────────────────────────┘
+```
+
+**Design rationale** (C3, Principle 5): Quality layers are cumulative. Layer 1
+runs on every commit (automated). Layer 2 runs on every PR (human + machine).
+Layer 3 runs on every release (governance artifact).
+
+### 2.2 Artifact Scopes
+
+```
+┌──────────────────────────────────────────┐
+│             PROJECT SCOPE                │
+│  *.sh, Makefile, Dockerfile,             │
+│  docker-compose.yml, .github/workflows/* │
+│  scripts/*, hooks/*                      │
+├──────────────────────────────────────────┤
+│             USER SCOPE                   │
+│  ~/.zshrc, ~/.bashrc, ~/.profile,        │
+│  ~/.bash_profile, ~/.zprofile,           │
+│  ~/.config/pzsh/*, ~/.bashrsrc           │
+├──────────────────────────────────────────┤
+│             SYSTEM SCOPE                 │
+│  /etc/profile, /etc/bash.bashrc,         │
+│  /etc/zsh/zshrc, /etc/environment        │
+│  (read-only audit, no modification)      │
+└──────────────────────────────────────────┘
+```
+
+### 2.3 pzsh Integration
+
+bashrs comply is a peer to pzsh, not a dependency. When pzsh is installed:
+
+| Feature | Without pzsh | With pzsh |
+|---------|-------------|-----------|
+| `~/.zshrc` analysis | bashrs config analyze | bashrs + pzsh performance profile |
+| Startup budget | Not checked | Enforced (<10ms, pzsh invariant) |
+| Plugin audit | Skip | pzsh plugin compliance check |
+| Config compilation | Skip | pzsh compile verification |
+| Slow pattern detection | bashrs lint only | bashrs lint + pzsh lint (unified) |
+
+**Discovery protocol**:
+```
+1. Check PATH for `pzsh` binary
+2. If found: pzsh --version → extract version
+3. If >= 1.0.0: enable pzsh integration features
+4. If not found: degrade gracefully, skip pzsh-specific checks
+```
+
+**Rationale** (C3, Principle 11 — Respect your partners): pzsh manages shell
+startup performance. bashrs manages shell safety. Neither subsumes the other.
+Comply bridges them.
+

+
+### 3.2 `bashrs comply init`
+
+Initialize compliance tracking for a project.
+
+```bash

+```
+
+**Output**: Creates `.bashrs/comply.toml`:

+pzsh = "auto"             # auto | enabled | disabled
+pmat = "auto"             # auto | enabled | disabled
+```
+
+### 3.3 `bashrs comply check`
+
+**Layer 1: Jidoka (自働化)** — Automated stop-the-line verification.
+
+```bash
+bashrs comply check [OPTIONS]
+
+Options:
+  -p, --path <PATH>         Project path [default: .]
+  --scope <SCOPE>           Scope to check [default: project]
+  --strict                  Exit with error if non-compliant
+  --failures-only           Show only failures
+  -f, --format <FMT>        Output format [default: text]
+  -o, --output <FILE>       Write output to file
+```
+
+**Compliance Rules (COMPLY-001 through COMPLY-010)**:
+
+| Rule | Name | Falsification Test | Citation |
+|------|------|--------------------|----------|
+| COMPLY-001 | POSIX Compliance | `shellcheck -s sh <file>` returns 0 | C5, C6 |
+| COMPLY-002 | Determinism | No `$RANDOM`, `$$`, `date +%s`, `mktemp` without seed | C1 §6 |
+| COMPLY-003 | Idempotency | All `mkdir` → `mkdir -p`, `rm` → `rm -f`, `ln` → `ln -sf` | C2 Ch.3 |
+| COMPLY-004 | Security | SEC001-SEC008 pass (no eval injection, no curl\|bash) | C5, C7 |
+| COMPLY-005 | Variable Quoting | All `$VAR` → `"${VAR}"` in non-arithmetic contexts | C5 §4.3 |
+| COMPLY-006 | ShellCheck Clean | `shellcheck --severity=warning` returns 0 | C5 |
+| COMPLY-007 | Makefile Safety | No shell injection in recipes, proper quoting | C5 |
+| COMPLY-008 | Dockerfile Best Practices | docker007-012 rules pass | C7 |
+| COMPLY-009 | Config Hygiene | No PATH duplicates, proper sourcing order | C3 P.5 |
+| COMPLY-010 | pzsh Budget | Shell startup < 10ms (when pzsh available) | pzsh invariant |
+
+**Falsification methodology** (C1): Each rule is expressed as a falsifiable
+hypothesis. The check attempts to **falsify** compliance. If the falsification
+attempt fails (no violations found), the artifact is provisionally compliant.
+A single counterexample refutes the claim.
+
+**Output example**:
+
+```
+bashrs comply check
+═══════════════════════════════════════════════════════════
+  COMPLIANCE CHECK — Layer 1 (Jidoka)
+═══════════════════════════════════════════════════════════

+```
+
+### 3.4 `bashrs comply review`
+
+**Layer 2: Genchi Genbutsu (現地現物)** — Go and see. Evidence-based review
+with reproducibility requirements.
+
+```bash
+bashrs comply review [OPTIONS]
+
+Options:
+  -p, --path <PATH>         Project path [default: .]
+  -f, --format <FMT>        Output format [default: markdown]
+  -o, --output <FILE>       Write output to file
+  --scope <SCOPE>           Scope to review [default: project]
+```
+
+**Review checklist** (generated per-artifact):
+
+```markdown
+## Review: scripts/deploy.sh
+
+### Hypothesis
+> This script is deterministic, idempotent, and POSIX-compliant.
+
+### Falsification Attempts
+| # | Test | Result | Evidence |
+|---|------|--------|----------|
+| 1 | shellcheck -s sh scripts/deploy.sh | PASS | Exit code 0, 0 warnings |
+| 2 | grep -n '$RANDOM\|$$\|date +%s' | PASS | No matches |
+| 3 | grep -n 'mkdir [^-]' (missing -p) | PASS | No matches |
+| 4 | bashrs lint scripts/deploy.sh | PASS | 0 violations |
+| 5 | Idempotency: run twice, diff output | PASS | Identical output |
+
+### Reproducibility
+```
+$ shellcheck -s sh scripts/deploy.sh; echo $?
+0
+$ bashrs lint scripts/deploy.sh --format json | jq '.violations | length'
+0
+```
+
+### Verdict
+- [x] Hypothesis not falsified after 5 attempts
+- [x] All evidence reproducible
+- [x] Reviewer: <pending human review>
+```
+
+**Rationale** (C2, C3 Principle 12): "Go and see for yourself to thoroughly
+understand the situation." Layer 2 requires a human reviewer to verify machine
+evidence. The checklist provides reproducible commands so reviewers can confirm
+findings independently.
+
+### 3.5 `bashrs comply audit`
+
+**Layer 3: Kansa (監査)** — Governance. Signed, immutable compliance artifact.
+
+```bash
+bashrs comply audit [OPTIONS]
+
+Options:
+  -p, --path <PATH>         Project path [default: .]
+  -f, --format <FMT>        Output format [default: json]
+  -o, --output <FILE>       Write output to file
+  --scope <SCOPE>           Scope to audit [default: all]
+```
+
+**Requires**: Clean git state (no uncommitted changes).
+
+**Output** (JSON audit artifact):
+
+```json
+{
+  "schema": "bashrs-comply-audit-v1",
+  "timestamp": "2026-02-07T10:30:00Z",
+  "git_sha": "d8d88240ab...",
+  "git_clean": true,
+  "bashrs_version": "7.1.0",
+  "pzsh_version": "1.2.0",
+  "scopes": {
+    "project": {
+      "artifacts": 14,
+      "compliant": 14,
+      "score": 98,
+      "grade": "A+"
+    },
+    "user": {
+      "artifacts": 2,
+      "compliant": 2,
+      "score": 95,
+      "grade": "A+"
+    }
+  },
+  "rules": {
+    "COMPLY-001": { "tested": 16, "passed": 16, "falsified": 0 },
+    "COMPLY-002": { "tested": 16, "passed": 16, "falsified": 0 },
+    "COMPLY-003": { "tested": 16, "passed": 15, "falsified": 1 },
+    "...": "..."
+  },
+  "falsification_summary": {
+    "total_attempts": 160,
+    "successful_falsifications": 1,
+    "unfalsified_claims": 159,
+    "methodology": "Popperian (C1)"
+  },
+  "pzsh_integration": {
+    "startup_ms": 0.003,
+    "budget_ms": 10,
+    "within_budget": true
+  },
+  "signature": {
+    "method": "git-commit-sha",
+    "value": "d8d88240ab..."
+  }
+}
+```
+
+**Rationale** (C1 §10, C4): The audit artifact is a snapshot of falsification
+results at a specific git commit. It provides:
+1. **Reproducibility**: Any claim can be re-tested at the recorded SHA
+2. **Immutability**: Tied to git commit, cannot be retroactively changed
+3. **Completeness**: Every rule tested against every artifact
+4. **Sovereignty**: The project owns its compliance evidence
+
+### 3.6 `bashrs comply track`
+
+Manage tracked artifacts.
+
+```bash
+bashrs comply track [OPTIONS] <ACTION> [PATHS...]
+
+Actions:
+  add       Add artifacts to tracking
+  remove    Remove artifacts from tracking
+  list      List tracked artifacts
+  discover  Auto-discover artifacts in project
+
+Options:
+  --scope <SCOPE>   Scope [default: project]
+  --recursive       Discover recursively
+```
+
+**Examples**:
+
+```bash
+# Auto-discover all shell artifacts
+bashrs comply track discover --recursive
+
+# Add user configs to tracking
+bashrs comply track add --scope user ~/.zshrc ~/.bashrc
+
+# List all tracked artifacts
+bashrs comply track list --scope all
+
+# Add pzsh config
+bashrs comply track add --scope user ~/.config/pzsh/config.toml
+```
+
+### 3.7 `bashrs comply enforce`
+
+Install git hooks for pre-commit compliance enforcement.
+
+```bash
+bashrs comply enforce [OPTIONS]
+
+Options:
+  --tier <TIER>     Enforcement tier [default: 1]
+                    1 = fast (COMPLY-001,005,006 only, <5s)
+                    2 = standard (all rules, <30s)
+                    3 = strict (all rules + pzsh budget, <60s)
+  --uninstall       Remove enforcement hooks
+```
+
+**Hook behavior**: On pre-commit, runs `bashrs comply check --strict` on staged
+shell artifacts. Blocks commit if non-compliant. This is Jidoka: stop the line
+when a defect is detected (C2, Ch. 3).
+
+### 3.8 `bashrs comply report`
+
+Generate a compliance report (human, JSON, or markdown).
+
+```bash
+bashrs comply report [OPTIONS]
+
+Options:
+  -p, --path <PATH>         Project path [default: .]
+  -f, --format <FMT>        Output format [default: markdown]
+  -o, --output <FILE>       Write output to file
+  --include-history          Include compliance history over time
+  --scope <SCOPE>            Scope [default: all]
+```
+
+### 3.9 `bashrs comply diff`
+
+Show compliance changes since last recorded check.
+
+```bash
+bashrs comply diff [OPTIONS]
+
+Options:
+  --since <SHA>     Compare against specific commit
+  --since-last      Compare against last comply check
+```
+
+### 3.10 `bashrs comply migrate`
+
+Migrate compliance config to latest bashrs standards.
+
+```bash
+bashrs comply migrate [OPTIONS]
+
+Options:
+  --dry-run         Show changes without applying
+  --from <VERSION>  Source version [default: auto-detect]
+```
+
+---
+
+## 4. Artifact Discovery
+
+### 4.1 Project Scope Discovery
+
+```
+Glob patterns (searched in project root):
+  *.sh
+  scripts/**/*.sh
+  bin/**/*.sh
+  hooks/**/*.sh
+  .github/workflows/*.yml
+  .github/workflows/*.yaml
+  .husky/*
+  Makefile
+  makefile
+  GNUmakefile
+  *.mk
+  Dockerfile
+  Dockerfile.*
+  docker-compose.yml
+  docker-compose.yaml
+  .dockerignore
+  .devcontainer/devcontainer.json
+  .bashrsignore
+```
+
+### 4.2 User Scope Discovery
+
+```
+Known paths (platform-aware):
+  ~/.zshrc
+  ~/.bashrc
+  ~/.bash_profile
+  ~/.profile
+  ~/.zprofile
+  ~/.zshenv
+  ~/.zlogout
+  ~/.bash_logout
+  ~/.config/pzsh/config.toml      (pzsh config)
+  ~/.config/pzsh/plugins.toml     (pzsh plugins)
+  ~/.config/bashrs/comply.toml    (bashrs user config)
+  $XDG_CONFIG_HOME/pzsh/*         (XDG-compliant pzsh)
+```
+
+### 4.3 System Scope Discovery (read-only)
+
+```
+Known paths (audit only, never modified):
+  /etc/profile
+  /etc/bash.bashrc
+  /etc/zsh/zshrc
+  /etc/zsh/zshenv
+  /etc/environment
+  /etc/shells
+```
+
+**System scope constraint** (C7): bashrs comply NEVER modifies system files.
+System scope is audit-only. Any remediation must be performed manually by an
+administrator. This is a safety constraint, not a convenience trade-off.
+
+---
+
+## 5. Scoring Model
+
+### 5.1 Per-Artifact Score
+
+Each artifact is scored 0-100:
+
+```
+score = Σ(rule_weight × rule_pass) / Σ(rule_weight) × 100
+```
+
+| Rule | Weight | Rationale |
+|------|--------|-----------|
+| COMPLY-001 (POSIX) | 20 | Portability is foundational (C5) |
+| COMPLY-002 (Determinism) | 15 | Reproducibility requirement (C1, C4) |
+| COMPLY-003 (Idempotency) | 15 | Safe re-run requirement (C2) |
+| COMPLY-004 (Security) | 20 | Non-negotiable safety (C7) |
+| COMPLY-005 (Quoting) | 10 | Injection prevention (C5) |
+| COMPLY-006 (ShellCheck) | 10 | Industry standard validation |
+| COMPLY-007 (Makefile) | 5 | Format-specific (Makefile only) |
+| COMPLY-008 (Dockerfile) | 5 | Format-specific (Dockerfile only) |
+| COMPLY-009 (Config) | 5 | Scope-specific (user configs only) |
+| COMPLY-010 (pzsh) | 5 | Optional (only when pzsh present) |
+
+Format-specific rules (007-010) only apply to matching artifacts. Weights are
+renormalized per artifact.
+
+### 5.2 Project Score
+
+```
+project_score = Σ(artifact_score) / artifact_count
+```
+
+### 5.3 Grade Scale
+
+| Grade | Score Range | Interpretation |
+|-------|-------------|----------------|
+| A+ | 95-100 | Exemplary compliance |
+| A | 85-94 | Strong compliance |
+| B | 70-84 | Adequate, needs improvement |
+| C | 50-69 | Below standard, remediation required |
+| F | 0-49 | Non-compliant, stop the line |
+
+### 5.4 Gateway Barrier (Popperian)
+
+Per Popper's demarcation criterion (C1, §4): a compliance claim below 60% is
+**unfalsifiable** (too many violations to meaningfully test). Below the gateway,
+the score reflects only the count of passing rules, not a quality assessment.
+
+---
+
+## 6. Falsification Protocol
+
+### 6.1 Methodology
+
+Every compliance rule is a **hypothesis** (C1):
+
+> H: "Artifact X satisfies rule COMPLY-NNN."
+
+The check attempts to **falsify** H by finding a counterexample. If no
+counterexample is found after exhaustive testing, H is **provisionally accepted**
+(not proven true — Popper's asymmetry).
+
+### 6.2 Falsification Tests
+
+| Rule | Hypothesis | Falsification Test |
+|------|-----------|-------------------|
+| COMPLY-001 | "X is POSIX-compliant" | Run `shellcheck -s sh X`. Any warning falsifies. |
+| COMPLY-002 | "X is deterministic" | Search for `$RANDOM`, `$$`, `date`, `mktemp` without seed. Any match falsifies. |
+| COMPLY-003 | "X is idempotent" | Search for `mkdir` without `-p`, `rm` without `-f`, `ln` without `-sf`. Any match falsifies. |
+| COMPLY-004 | "X is secure" | Run bashrs SEC001-SEC008. Any violation falsifies. |
+| COMPLY-005 | "X quotes all variables" | Run bashrs SC2086 equivalent. Any unquoted expansion falsifies. |
+| COMPLY-006 | "X passes shellcheck" | Run `shellcheck --severity=warning X`. Any finding falsifies. |
+| COMPLY-007 | "Makefile Y is safe" | Run bashrs make lint Y. Any violation falsifies. |
+| COMPLY-008 | "Dockerfile Z follows best practices" | Run bashrs dockerfile lint Z. Any violation falsifies. |
+| COMPLY-009 | "Config C is hygienic" | Run bashrs config lint C. Any violation falsifies. |
+| COMPLY-010 | "Shell startup is within budget" | Run `pzsh bench`. p99 > 10ms falsifies. |
+
+### 6.3 Progressive Falsification (Lakatos)
+
+Following Lakatos (C8), the comply system distinguishes between:
+
+- **Progressive compliance**: New rules added, existing rules strengthened,
+  falsification coverage increases over time. This indicates a healthy project.
+- **Degenerating compliance**: Rules weakened, exceptions added, violations
+  suppressed. This indicates compliance theater.
+
+The `bashrs comply report --include-history` command tracks this trajectory.
+
+---
+
+## 7. pzsh Peer Protocol
+
+### 7.1 Discovery
+
+```rust
+fn discover_pzsh() -> Option<PzshInfo> {
+    // 1. Check PATH
+    let path = which("pzsh")?;
+    // 2. Get version
+    let version = exec("pzsh --version")?;
+    // 3. Check compatibility
+    if version >= "1.0.0" { Some(PzshInfo { path, version }) }
+    else { None }
+}
+```
+
+### 7.2 Integration Points
+
+| bashrs comply | pzsh | Data Flow |
+|--------------|------|-----------|
+| `check --scope user` | `pzsh lint` | bashrs invokes pzsh lint on zshrc |
+| `check COMPLY-010` | `pzsh bench` | bashrs reads pzsh benchmark result |
+| `track discover` | `pzsh status` | bashrs discovers pzsh-managed configs |
+| `audit` | `pzsh profile` | bashrs includes pzsh profile in audit |
+
+### 7.3 Graceful Degradation
+
+When pzsh is not installed:
+- COMPLY-010 is skipped (not counted in score)
+- pzsh-specific config paths are still tracked if files exist
+- No error, just an info message: "pzsh not found, skipping COMPLY-010"

+## 11. Relationship to Existing Commands
+
+| Existing Command | Comply Equivalent | Relationship |
+|-----------------|-------------------|--------------|
+| `bashrs lint` | COMPLY-004, 005, 006 | Comply invokes lint internally |
+| `bashrs purify` | Remediation for COMPLY-002, 003 | `comply --fix` calls purify |
+| `bashrs gate` | COMPLY check tier 1 | Gate is subset of comply |
+| `bashrs audit` | Single-file audit | Comply audits all artifacts |
+| `bashrs config lint` | COMPLY-009 | Comply invokes config lint |
+| `bashrs make lint` | COMPLY-007 | Comply invokes make lint |
+| `bashrs dockerfile lint` | COMPLY-008 | Comply invokes dockerfile lint |
+| `pmat comply` | Peer (Rust project) | bashrs comply = shell artifacts |
+
+**Principle**: bashrs comply is an orchestrator. It does not reimplement linting,
+purification, or analysis. It invokes existing bashrs commands and aggregates
+results into a compliance assessment.
+
+---
+
+## 12. Non-Goals
+
+1. **Replace pmat comply** — pmat handles Rust code; bashrs handles shell artifacts
+2. **Modify system files** — System scope is read-only audit
+3. **Replace shellcheck** — ShellCheck is invoked as a dependency, not replaced
+4. **Enforce pzsh installation** — pzsh is optional; comply degrades gracefully
+5. **Configuration management** — comply tracks compliance, not configuration state

+# Corpus-Driven Transpilation Quality Specification
+
+**Version**: 2.1.0
+**Date**: 2026-02-08
+**Status**: Draft (v2.1 — merged ML linting spec BASHRS-SPEC-ML-001 into Section 11.13)
+**Methodology**: EXTREME TDD + Popperian Falsification + Toyota Production System + Metamorphic Testing
+
+## Executive Summary
+
+This specification defines three corpus repositories in the `paiml` GitHub organization for measuring and improving bashrs transpilation quality across three target formats: Bash (purified POSIX shell), Makefiles, and Dockerfiles. Each corpus serves as a **falsifiable test oracle** -- a curated collection of Rust DSL inputs paired with expected outputs that enables continuous, automated measurement of transpilation correctness.
+
+**Targets**:
+- 99% transpilation success rate across all three formats
+- 95% test coverage on transpiled outputs (Rust source is testable; outputs are unit-verifiable)
+- Zero regression tolerance (Andon cord / STOP THE LINE on any decrease)
+
+**Repositories**:
+
+| Repository | Format | Initial Corpus Size | Target Rate |
+|---|---|---|---|
+| `paiml/bashrs-corpus-bash` | POSIX shell (purified) | 200 programs | 99% |
+| `paiml/bashrs-corpus-makefile` | GNU Make | 150 programs | 99% |
+| `paiml/bashrs-corpus-dockerfile` | Dockerfile | 150 programs | 99% |

+
+## 1. Theoretical Foundation
+
+### 1.1 Popperian Falsification Applied to Transpiler Validation
+
+Karl Popper's critical rationalism holds that scientific theories cannot be verified, only falsified (Popper, 1959). Applied to transpiler engineering, this means:
+
+> A transpiler is not "correct" because it passes N tests. It is **not yet falsified** because no test in the corpus has demonstrated incorrect behavior.
+
+Each corpus entry is a **potential falsifier**: a specific input-output pair that could demonstrate transpilation failure. The corpus grows monotonically -- entries are never removed, only added. A 99% transpilation rate means that fewer than 1% of potential falsifiers have succeeded in demonstrating a defect.
+
+**Falsification Protocol**:
+1. Every corpus entry MUST have an expected output (the "prediction")
+2. Every transpilation run produces an actual output (the "observation")
+3. Any mismatch between prediction and observation is a **falsification event**
+4. Falsification events trigger STOP THE LINE (see Section 5)
+
+> "In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality." -- Popper, K. (1959). *The Logic of Scientific Discovery*. Routledge, p. 314.
+
+### 1.2 The Cardinal Rule: Fix the Transpiler, Never the Corpus
+
+**THIS IS THE MOST IMPORTANT PRINCIPLE IN THIS ENTIRE SPECIFICATION.**
+
+When a corpus entry fails, there are exactly two possible responses:
+
+| Response | Correct? | Rationale |
+|----------|----------|-----------|
+| Fix the transpiler so the entry passes | **YES** | The corpus found a real defect. The transpiler is the system under test. |
+| Modify or remove the corpus entry to hide the failure | **NEVER** | This is scientific fraud -- destroying evidence that falsifies your hypothesis. |
+
+The corpus is the **test oracle**. It represents ground truth. The transpiler is the **system under test**. When the system fails the oracle, you fix the system.
+
+**Why this matters**: The natural human temptation when a test fails is to "fix the test." In corpus-driven development, this impulse must be actively resisted. A failing corpus entry is not a bug in the test -- it is a **discovered defect** in the transpiler. It is a gift. It tells you exactly where to improve.
+
+**Analogy**: In manufacturing, when a part fails quality inspection, you fix the manufacturing process, not the inspection gauge. Toyota calls this "respect for the process" (Liker, 2004, Principle 6).
+
+**Enforcement**:
+- Corpus entries are **append-only**. Entries are NEVER removed or weakened.
+- The `convergence.log` records the corpus size monotonically increasing.
+- Code review MUST reject any PR that modifies expected outputs to match transpiler bugs.
+- CI MUST flag any reduction in corpus entry count as a P0 violation.
+
+### 1.3 The Infinite Corpus: What Happens at 100%
+
+Reaching 100% on the current corpus does **not** mean the transpiler is correct. It means the current set of falsifiers has been exhausted. The correct response is to **add harder entries**.
+
+**The corpus growth cycle**:
+
+```
+    ┌─────────────────────────────────────────────────────────┐
+    │                                                         │
+    ▼                                                         │
+ [Add new corpus entries]                                     │
+    │                                                         │
+    ▼                                                         │
+ [Run corpus → measure rate]                                  │
+    │                                                         │
+    ├── Rate < 99% ──► [Fix transpiler] ──► [Run again] ──┘  │
+    │                                                         │
+    └── Rate = 100% ──► [Add HARDER entries] ─────────────────┘
+```
+
+**When you reach 100% on the current corpus**:
+1. **Celebrate briefly** -- you've exhausted this level of difficulty
+2. **Immediately add new entries** from the next tier or new edge cases
+3. **Target constructs not yet covered**: new Rust syntax, deeper nesting, more complex patterns
+4. **Mine real-world scripts** for patterns not yet in the corpus
+5. **Run mutation testing** to find transpiler code paths not exercised by any entry
+6. **Never declare victory** -- the corpus is a living document that grows forever
+
+**The asymptotic model**: In practice, each round of "reach 100%, add harder entries" follows a sigmoid curve. The transpiler improves rapidly at first (low-hanging fruit), then improvements slow as edge cases get harder. This is expected and healthy -- it means the corpus is doing its job of pushing the transpiler toward correctness.
+
+> "The strength of a theory lies not in its ability to avoid falsification, but in its ability to survive increasingly severe tests." -- Lakatos, I. (1978). *The Methodology of Scientific Research Programmes*. Cambridge University Press, p. 33.

+| Ongoing | 900+ entries | 99%+ | Continuous addition of harder entries forever | ONGOING |
+
+The corpus has no maximum size. If you run out of ideas for new entries, run mutation testing -- every surviving mutant reveals a corpus gap.
+
+### 1.4 Toyota Production System: Jidoka and Kaizen
+
+The Toyota Production System (TPS) provides two principles directly applicable to corpus-driven quality (see also Section 1.2 -- the cardinal rule ensures Jidoka is applied to the transpiler, not the corpus):
+
+**Jidoka (Autonomation)**: Build quality into the process by stopping the line when a defect is detected (Liker, 2004). In our context:
+- Every CI run executes the full corpus
+- Any falsification event halts the pipeline (Andon cord)
+- No release proceeds until the corpus passes at 99%+
+
+**Kaizen (Continuous Improvement)**: Improvement through small, incremental changes measured against objective baselines (Imai, 1986). In our context:
+- Transpilation rate is tracked per-iteration (convergence log)
+- Each iteration adds corpus entries or fixes transpilation defects
+- The corpus grows, making the quality bar strictly monotonically increasing
+
+> "The Toyota Way is about processes and results... Test every process, improve every process, and involve every worker." -- Liker, J. K. (2004). *The Toyota Way: 14 Management Principles*. McGraw-Hill, p. 37.
+
+### 1.5 Mutation Testing as Second-Order Falsification
+
+Mutation testing (DeMillo et al., 1978) provides **second-order falsification**: it tests whether the tests themselves are adequate. A mutant that survives indicates a gap in the test oracle.
+
+Applied to corpus validation:
+- Inject mutations into the transpiler (cargo-mutants)
+- If a mutant produces different output but no corpus entry catches it, the corpus has a gap
+- Target: 90% mutation kill rate on transpiler code
+
+> "Mutation testing provides a systematic approach to evaluating test suite adequacy by introducing small syntactic changes to source code." -- DeMillo, R. A., Lipton, R. J., & Sayward, F. G. (1978). "Hints on Test Data Selection: Help for the Practicing Programmer." *IEEE Computer*, 11(4), 34-41.

+Tier assignment follows the **principle of progressive difficulty** (Vygotsky, 1978): each tier builds on constructs validated in the previous tier, creating a zone of proximal development for the transpiler.

+## 4. Scoring System
+
+### 4.1 100-Point Transpilation Quality Score
+
+Adapted from depyler's Pareto single-shot scoring methodology (Gift, 2025):
+
+| Category | Points | Weight | Description |
+|----------|--------|--------|-------------|
+| A. Transpilation Success | 40 | 40% | Does the input transpile without error? |
+| B. Output Correctness | 25 | 25% | Does output match expected semantics? |
+| C. Test Coverage | 15 | 15% | Are transpiled outputs verified by tests? |
+| D. Lint Compliance | 10 | 10% | Does output pass format-specific linting? |
+| E. Determinism | 10 | 10% | Is output byte-identical across runs? |
+
+**Scoring Formula**:
+
+```
+Score = (A_success_ratio × 40)
+      + (B_correct_ratio × 25)
+      + (C_coverage_ratio × 15)
+      + (D_lint_pass_ratio × 10)
+      + (E_determinism_ratio × 10)
+```
+
+**Gateway Logic** (Popperian falsification barrier):
+- If A < 24 (60% transpilation), B through E are scored as 0
+- Rationale: A transpiler that fails to produce output cannot have correct, tested, or lint-clean output
+
+**Grade Scale**:
+
+| Grade | Score Range | Interpretation |
+|-------|------------|----------------|
+| A+ | 97-100 | Production-ready, fully validated |
+| A | 90-96 | Near-production, minor gaps |
+| B | 80-89 | Good quality, known limitations |
+| C | 70-79 | Functional, significant gaps |
+| D | 60-69 | Partially functional |
+| F | < 60 | Not yet viable |
+
+**Target**: Grade A+ (97+) for all three corpus repositories.
+
+### 4.2 Per-Entry Scoring
+
+Each corpus entry receives an individual score:
+
+```toml
+# Automated scoring output
+[score]
+transpiles = true         # +40 (A: success)
+output_correct = true     # +25 (B: correctness)
+has_test = true           # +15 (C: coverage)
+lint_clean = true         # +10 (D: lint)
+deterministic = true      # +10 (E: determinism)
+total = 100               # Sum
+grade = "A+"
+```
+
+### 4.3 Aggregate Scoring
+
+The repository-level score is the weighted mean of all entry scores:
+
+```
+Repo_Score = Σ(entry_score × tier_weight) / Σ(tier_weight)
+```
+
+Where tier weights reflect difficulty:
+- Tier 1: weight 1.0
+- Tier 2: weight 1.5
+- Tier 3: weight 2.0
+- Tier 4: weight 2.5
+- Tier 5: weight 3.0
+
+This weighting ensures that production-quality programs contribute more to the overall score, following the Pareto principle: the hardest 20% of entries provide 40% of the quality signal (Juran, 1951).
+
+---
+
+## 5. Convergence Tracking and Kaizen Protocol
+
+### 5.1 Convergence Log
+
+Each corpus repository maintains a `convergence.log` tracking transpilation rate over iterations:
+
+```
+# convergence.log (ACTUAL DATA - updated 2026-02-06)
+# iter | date       | total | pass | fail | rate   | delta  | score | grade | notes

+```
+
+**Final Corpus Composition**:
+- **Bash**: 200 entries (B-001..B-200) — target: 200 ✅
+- **Makefile**: 150 entries (M-001..M-150) — target: 150 ✅
+- **Dockerfile**: 150 entries (D-001..D-150) — target: 150 ✅
+- **Total**: 500 entries — target: 500 ✅
+
+**Bugs Fixed (Transpiler Improvements)**:
+1. **u16 type support** (D-006): Added `Type::U16`, `Literal::U16(u16)` to AST, parser, IR, all emitters
+2. **Array/slice reference expressions** (D-007, M-003, M-004): Added `SynExpr::Array`, `SynExpr::Reference`, `SynType::Slice` handlers
+3. **Assignment expressions** (B-016): Added `SynExpr::Assign` → `convert_assign_stmt()` in parser
+4. **Compound assignment operators** (B-036/B-037/B-038): Desugar `+=`, `-=`, `*=`, `/=`, `%=` to binary expressions
+5. **eprintln! macro** (B-039): Parser + `rash_eprintln` runtime function with `>&2` redirect
+6. **2-arg target()** (M-026/M-027/M-028/M-029): Makefile `target()/phony_target()` now accept 2 or 3 args
+7. **CommandSubst in arithmetic** (B-121): `emit_arithmetic_operand` now handles `ShellValue::CommandSubst` for function return values in `$((...))` expressions
+8. **format! macro expression** (B-171): Added `SynExpr::Macro` handler in `convert_expr()` for `format!` and `vec!` macro expressions
+
+### 5.2 Convergence Criteria
+
+The transpiler is considered **converged at a given corpus level** when:
+
+1. **Rate threshold**: Transpilation rate >= 99% for 3 consecutive iterations
+2. **Stability**: Delta < 0.5% for 3 consecutive iterations (approaching asymptote)
+3. **Corpus growth**: Corpus size >= initial target (200/150/150)
+4. **No regressions**: No entry that previously passed has started failing
+
+**CRITICAL: Convergence is temporary.** When convergence is reached, the corpus MUST be expanded with harder entries (see Section 1.3). Convergence at N entries triggers growth to N+50 entries. There is no final convergence -- only convergence at the current difficulty level.
+
+This follows the statistical process control methodology of Shewhart (1931): a process is "in control" when variation falls within expected bounds over sustained measurement. But a controlled process operating within limits should be challenged with tighter limits.
+
+> "A phenomenon will be said to be controlled when, through the use of past experience, we can predict, at least within limits, how the phenomenon may be expected to vary in the future." -- Shewhart, W. A. (1931). *Economic Control of Quality of Manufactured Product*. Van Nostrand, p. 6.
+
+### 5.3 Regression Detection (Jidoka)
+
+**Andon Cord Protocol**:
+
+When CI detects a regression (an entry that previously passed now fails):
+
+1. **STOP THE LINE**: Pipeline fails, no releases proceed
+2. **Root cause analysis**: Five Whys applied to the regression
+3. **Fix with EXTREME TDD**: RED -> GREEN -> REFACTOR cycle
+4. **Regression test**: The failing entry becomes a permanent regression test
+5. **Resume**: Only after full convergence suite passes
+
+This implements Toyota's Jidoka principle: "stop and fix problems as they occur rather than pushing them down the line" (Ohno, 1988).
+
+> "If a defective part or equipment malfunction is discovered, the affected machine automatically stops, and operators stop work and correct the problem." -- Ohno, T. (1988). *Toyota Production System: Beyond Large-Scale Production*. Productivity Press, p. 6.

+
+## 6. Test Coverage Strategy
+
+### 6.1 Dual-Layer Testing
+
+The 95% coverage target is achieved through two complementary testing layers:
+
+**Layer 1: Rust-Side Unit Tests (the Rust DSL source is testable)**
+
+```rust
+#[test]
+fn test_corpus_B001_hello_world() {
+    let rust_input = r#"fn main() { println!("hello"); }"#;
+    let config = Config::default();
+    let output = bashrs::transpile(rust_input, config).unwrap();
+
+    assert!(output.contains("echo 'hello'"));
+    assert!(!output.contains("$RANDOM"));  // Determinism
+    assert!(!output.contains(":latest"));   // No latest tags (Docker)
+}
+```
+
+**Layer 2: Output Verification Tests (the transpiled output is verifiable)**
+
+```rust
+#[test]
+fn test_corpus_B001_output_quality() {
+    let output = transpile_corpus_entry("tier-1-trivial/001-hello-world");
+
+    // Structural verification
+    assert!(output.starts_with("#!/bin/sh"));
+    assert!(output.contains("set -euf"));
+
+    // Lint verification
+    let lint = bashrs::lint_shell(&output);
+    assert_eq!(lint.errors.len(), 0, "No SEC/DET/IDEM violations");
+
+    // Determinism verification
+    let output2 = transpile_corpus_entry("tier-1-trivial/001-hello-world");
+    assert_eq!(output, output2, "Transpilation must be deterministic");
+}
+```
+
+### 6.2 Coverage Measurement
+
+```bash
+# Measure coverage of corpus test suite
+cargo llvm-cov --package bashrs-corpus-bash --lcov --output-path lcov.info
+
+# Target: 95% line coverage across:
+# - Transpiler code exercised by corpus
+# - Output verification tests
+# - Registry and runner infrastructure
+```
+
+### 6.3 Property-Based Testing
+
+Each tier includes property tests that generate random valid inputs within the tier's construct space:
+
+```rust
+proptest! {
+    #[test]
+    fn prop_tier1_always_transpiles(
+        var_name in "[a-z][a-z0-9_]{0,10}",
+        value in "[a-zA-Z0-9 ]{1,50}"
+    ) {
+        let input = format!(r#"fn main() {{ let {var_name} = "{value}"; }}"#);
+        let result = bashrs::transpile(&input, Config::default());
+        prop_assert!(result.is_ok(), "Tier 1 constructs must always transpile");
+    }
+}
+```
+
+### 6.4 Mutation Testing as Test Quality Validation
+
+Following DeMillo et al. (1978), mutation testing validates that the corpus tests are meaningful:
+
+```bash
+# Run mutation testing on transpiler code
+cargo mutants --file rash/src/emitter/posix.rs -- --test corpus
+
+# Target: >=90% mutation kill rate
+# Interpretation: 90% of transpiler mutations are caught by corpus tests
+```
+
+A surviving mutant indicates either:
+1. A gap in the corpus (add a new entry targeting the uncaught mutation)
+2. A redundancy in the transpiler (dead code that can be removed)
+
+---
+
+## 7. Compiler-in-the-Loop (CITL) Integration
+
+### 7.1 What is CITL for bashrs?
+
+Compiler-in-the-Loop (CITL) is a pattern from the depyler project (Gift, 2025) where the **compiler serves as an automated oracle** on every commit. In depyler, `rustc` is the compiler. In bashrs, **the bashrs linter IS the compiler**:
+
+| Format | CITL "Compiler" | Rules Applied |
+|--------|-----------------|---------------|
+| Bash (POSIX shell) | `bashrs::linter::rules::lint_shell()` | SEC001-SEC008, DET001-DET003, IDEM001-IDEM003 |
+| Makefile | `bashrs::linter::rules::lint_makefile()` | MAKE001-MAKE020 |
+| Dockerfile | `bashrs::linter::rules::lint_dockerfile()` | DOCKER001-DOCKER012 |
+
+We already have the compiler. The corpus runner already calls it (the "D: Lint Compliance" score). The unit tests on the transpiled output already close the loop. **CITL is not an external tool -- it is the combination of transpilation + linting + unit testing that already runs on every corpus entry.**
+
+The key insight from depyler: the loop must run **on every commit**, failures must **block the commit**, and compiler errors must **generate new corpus entries**.
+
+### 7.2 The CITL Loop: Every Commit, Every Entry
+
+```
+┌──────────────────────────────────────────────────────────────┐
+│                    EVERY COMMIT                               │
+│                                                               │
+│  1. Transpile all corpus entries (Rust DSL → Bash/Make/Docker)│
+│     │                                                         │
+│  2. For each transpiled output, run THREE validators:         │
+│     ├── Unit test: does output contain expected content?      │
+│     ├── Lint (CITL): lint_shell / lint_makefile /             │
+│     │   lint_dockerfile on the actual transpiled output       │
+│     └── Determinism: transpile twice, byte-compare            │
+│     │                                                         │
+│  3. Score each entry (100-point system) and aggregate         │
+│     │                                                         │
+│  4. If any previously-passing entry now fails:                │
+│     └── ANDON CORD → fix the TRANSPILER (Section 1.2)        │
+│                                                               │
+│  5. If rate = 100% on current corpus:                         │
+│     └── ADD HARDER ENTRIES (Section 1.3)                      │
+│                                                               │
+│  6. Lint violations on transpiled output become NEW entries:  │
+│     └── Violation → new corpus entry targeting that defect    │
+└──────────────────────────────────────────────────────────────┘
+```
+
+### 7.3 Lint Violation → Corpus Entry Pipeline (Self-Improving Corpus)
+
+When the bashrs linter flags a violation in transpiled output, that violation becomes a **new corpus entry**:
+
+```
+lint_shell(transpiled_output):
+  SEC003: Unquoted variable in command at line 5
+
+  → New corpus entry:
+    id: "B-031"
+    name: "unquoted-variable-in-command"
+    description: "SEC003: variable used in command argument must be quoted"
+    input: <the Rust DSL that produced the bad output>
+    expected_output: <corrected output with proper quoting>
+    lint_rule: "SEC003"
+```
+
+This creates a **self-improving cycle**: lint violations from CITL validation automatically generate new corpus entries, which drive transpiler fixes, which improve the rate. The corpus grows itself from linter feedback. This is the same pattern depyler uses with `rustc` errors, but our "compiler" is the bashrs linter.
+
+### 7.4 Pre-Commit Hook Integration
+
+Following the depyler pattern, corpus validation runs on every commit via pmat-managed hooks:
+
+```bash
+# .git/hooks/pre-commit (pmat-managed)
+#!/bin/sh
+set -euf
+
+# Run corpus unit tests (<30s)
+cargo test -p bashrs --lib -- corpus --quiet
+
+# Full corpus integration tests on CI
+# cargo test -p bashrs --test corpus_tests
+```
+
+On CI (GitHub Actions), the full corpus runs:
+
+```yaml
+- name: CITL Corpus Validation
+  run: cargo test -p bashrs --test corpus_tests
+```
+
+### 7.5 Convergence Log Tracks Lint Pass Rate

+The convergence log tracks the CITL (lint) pass rate alongside transpilation rate. The gap between them reveals "hidden invalidity" -- output that transpiles but violates lint rules:
+
+```
+# convergence.log
+# iter | date       | total | transpile | lint_pass | rate   | lint_rate | notes
+  1    | 2026-02-06 | 30    | 26        | 22        | 86.7%  | 73.3%    | Baseline: 4 AST gaps, 4 lint violations
+  2    | 2026-02-13 | 30    | 30        | 28        | 100%   | 93.3%    | Fixed AST, 2 SEC rule violations remain
+  3    | 2026-02-20 | 50    | 46        | 42        | 92.0%  | 84.0%    | Added 20 harder entries, rate dipped (healthy)
+  4    | 2026-02-27 | 50    | 50        | 49        | 100%   | 98.0%    | Recovered, one DOCKER003 violation
+  5    | 2026-03-06 | 80    | 76        | 72        | 95.0%  | 90.0%    | Added 30 more entries (Section 1.3)

+
+### Phase 3: Adversarial and Production Corpus (Weeks 9-12)
+
+**Objective**: Add adversarial edge cases and production scripts, reach 99% target.
+
+**Deliverables**:

+- Mutation testing adequacy criterion (DeMillo et al., 1978)
+
+### Phase 4: Continuous Growth and Perpetual Falsification (Ongoing -- Never Ends)
+
+**Objective**: The corpus never stops growing. When 100% is reached, add harder entries until the rate drops, then fix the transpiler again. Repeat forever.
+
+**The cardinal rule applies here most urgently** (Section 1.2): the temptation to "declare victory" and stop adding entries is the single greatest risk to long-term quality. A static corpus decays into a regression suite -- necessary, but insufficient.
+
+**Deliverables**:
+- Automated corpus contribution pipeline (PR template for new entries)
+- Monthly convergence report showing corpus SIZE growth (not just rate)
+- Quarterly adversarial audit (new injection patterns, new CVEs)
+- Mutation-testing-guided corpus expansion: every surviving mutant becomes a new entry
+- Integration with pmat quality scoring
+- **Minimum 10 new entries per month** (enforced by CI)
+
+**Kaizen Cycle** (Toyota PDCA applied to corpus growth):
+1. **Plan**: Run mutation testing to find untested transpiler code paths
+2. **Do**: Write corpus entries targeting those paths (they WILL fail initially)
+3. **Check**: Confirm the new entries fail (if they pass, the entry is too easy -- write harder ones)
+4. **Act**: Fix the transpiler to pass the new entries, then go back to Plan
+
+**The healthy cadence**:
+- Rate drops when new entries are added (this is GOOD -- it means the corpus is challenging)
+- Rate recovers as transpiler improves (this is the Kaizen improvement)
+- Rate reaches 100% again (this means it's time for more entries)
+- This cycle repeats indefinitely

+The corpus and convergence metrics are published to Hugging Face as open datasets on every release. This serves three purposes:
+1. **Reproducibility**: Anyone can download and re-run the corpus against any bashrs version
+2. **Training data**: The input/output pairs serve as training data for code generation models
+3. **Benchmarking**: Other transpiler projects can compare against the bashrs corpus

+**Model Publishing** (Oracle/CITL models):
+
+When the bashrs oracle or CITL pattern library is retrained from corpus data, the updated model is also pushed to Hugging Face:
+
+| HF Model | Contents | Update Frequency |
+|----------|----------|------------------|
+| `paiml/bashrs-oracle` | Error classification model trained on corpus failures | Monthly or on significant corpus growth |
+| `paiml/bashrs-citl-patterns` | Lint violation → fix pattern library (BM25 index) | Weekly with corpus updates |
+
+This follows the depyler pattern where the `depyler_oracle.apr` model is retrained after each overnight session and published for reproducibility.
+
+**Benefits of Hugging Face Publishing**:
+- **Open science**: Corpus is publicly available for peer review (Popperian transparency)
+- **Version tracking**: Every dataset version is immutable and linked to a git commit
+- **Training signal**: The input/output/score triples are directly usable as fine-tuning data
+- **Community growth**: External contributors can propose new corpus entries via HF discussions

+## 11. Quantifiable Correctness: Findings and Research Design (v2.0)
+
+### 11.1 Current System Findings (Audit 2026-02-07)
+
+An audit of the in-tree corpus implementation (`rash/src/corpus/`) identified six structural weaknesses that limit the system's ability to quantifiably measure transpilation correctness. Each finding is mapped to a specific code location and a research-backed remediation.
+
+#### Finding F1: Substring Containment as Correctness Metric (CRITICAL)
+
+**Location**: `rash/src/corpus/runner.rs:151`
+```rust
+output.contains(&entry.expected_output)
+```
+
+**Problem**: Output correctness (Category B, 25 points) is measured by substring containment — `actual_output.contains(expected_output)`. This means a transpiled output containing the expected string *plus arbitrary additional content* scores full marks. A transpiler that appends `; rm -rf /` to every correct output would still pass.
+
+**Severity**: CRITICAL — the 25-point correctness category (B) provides no meaningful signal. The current 100% convergence rate may mask latent defects.
+
+**Remediation — Three-Level Correctness Hierarchy**:
+
+| Level | Method | Points | Description |
+|-------|--------|--------|-------------|
+| L1 | Exact string match | 10/25 | `actual.trim() == expected.trim()` — baseline |
+| L2 | AST structural equivalence | 8/25 | Parse both to AST, compare semantically (ignoring whitespace, comments) |
+| L3 | Execution-based behavioral equivalence | 7/25 | Execute both in sandbox, compare stdout/stderr/exit code |
+
+**L2 Implementation — AST Comparison**: For shell scripts, parse both actual and expected output using the bashrs parser into `ShellAst`, then compare structurally. This eliminates false negatives from insignificant formatting differences while catching semantic divergence. For Makefiles and Dockerfiles, use format-specific structural comparison.
+
+Tree edit distance (Zhang & Shasha, 1989) provides a polynomial-time algorithm for comparing ordered labeled trees, directly applicable to AST comparison. Recent work by Huang et al. (2024) demonstrates AST edit distance as superior to token-level comparison for code similarity measurement.
+
+**L3 Implementation — Execution-Based Oracle**: For Tier 1-3 entries, execute both expected and actual output in an isolated sandbox (bubblewrap/firejail on Linux) and compare:
+- stdout (byte-exact)
+- stderr (pattern match)
+- exit code (exact)
+- filesystem side effects (diff of sandbox root)
+
+This follows the **differential testing** methodology (McKeeman, 1998), where the expected output serves as the reference implementation and the transpiled output is the system under test.
+
+> "Differential testing finds semantic bugs by providing the same input to different implementations of the same functionality and cross-referencing the outputs." — McKeeman, W. M. (1998). "Differential Testing for Software." *Digital Technical Journal*, 10(1), 100-107.
+
+#### Finding F2: Hardcoded Test Coverage Score
+
+**Location**: `rash/src/corpus/runner.rs:163`
+```rust
+has_test: true,  // hardcoded
+```
+
+**Problem**: Category C (Test Coverage, 15 points) always awards full marks because `has_test` is hardcoded to `true`. This category provides zero discriminative signal.
+
+**Remediation**: Replace with actual coverage measurement using `pmat query --coverage` integration (see Section 11.3). Each corpus entry should measure whether the transpiler code paths exercised by that entry are covered by unit tests:
+
+```
+C_score = (covered_transpiler_lines_for_entry / total_transpiler_lines_for_entry) × 15
+```
+
+This requires per-entry LLVM coverage tracing, achievable via `cargo llvm-cov report --json` with test-name filtering.
+
+#### Finding F3: Two Disconnected Oracle Systems
+
+**Locations**:
+- In-tree k-NN oracle: `rash/src/quality/oracle.rs` (1858 lines, 73-feature vector, k=5)
+- Standalone Random Forest oracle: `bashrs-oracle/src/lib.rs` (696 lines, 100 trees via `aprender`)
+
+**Problem**: Two independent ML systems classify transpilation errors but are not connected to each other or to the corpus runner. The in-tree oracle uses k-NN with 15 error categories; the standalone oracle uses Random Forest with 24 categories. Neither feeds classification results back into the corpus scoring system. Neither is trained on real corpus failure data.
+
+**Remediation — Unified Oracle Architecture**:
+
+```
+┌─────────────────────────────────────────────────────┐
+│                 Unified Oracle                        │
+│                                                       │
+│  ┌──────────┐   ┌──────────────┐   ┌─────────────┐  │

+│  │  online) │   │ (accurate,   │   │ (majority    │  │
+│  │          │   │  batch)      │   │  vote)       │  │
+│  └──────────┘   └──────────────┘   └─────────────┘  │
+│        ▲               ▲                   │          │
+│        │               │                   ▼          │
+│  ┌──────────────────────────────┐  ┌──────────────┐  │
+│  │ Corpus Failure Training Data │  │ Fix Pattern   │  │
+│  │ (real failures, not synthetic)│  │ Recommender  │  │
+│  └──────────────────────────────┘  └──────────────┘  │
+└─────────────────────────────────────────────────────┘
+```
+
+Ensemble classification combining k-NN and Random Forest improves prediction accuracy over either alone. Breiman (2001) demonstrated that Random Forests achieve lower generalization error through ensemble diversity, and combining with instance-based learners (k-NN) provides complementary bias-variance tradeoffs (Dietterich, 2000).
+
+#### Finding F4: Synthetic Training Data
+
+**Location**: `bashrs-oracle/src/lib.rs` — `Corpus::generate_synthetic(5000)`
+
+**Problem**: The standalone oracle trains on 5000 synthetically generated examples, not on real corpus failures. The synthetic generator creates plausible-looking feature vectors with random labels, meaning the model learns artificial correlations rather than real failure patterns.
+
+**Remediation**: Train exclusively on real corpus failure data. Every falsification event (corpus entry failure) generates a training example:
+
+```rust
+TrainingExample {
+    features: FeatureVector::extract(&diagnostic, &source_code),
+    label: error_category,  // manually classified on first occurrence
+    corpus_entry_id: "B-036",
+    transpiler_version: "6.60.0",
+    fix_applied: "compound_assign_desugar",
+}
+```
+
+With 500 corpus entries and 8 historical bugs (see Section 5.1), the current real training set is small. **Active learning** (Settles, 2012) addresses this by selecting the most informative examples for labeling: run the oracle on new corpus entries, and prioritize manual labeling of entries where the oracle is least confident.
+
+#### Finding F5: No Cross-Validation or Held-Out Test Set
+
+**Problem**: Neither oracle system uses cross-validation or a held-out test set. Model accuracy is unmeasured. The in-tree k-NN uses bootstrap patterns (PAT-001..PAT-015) as a fallback but never validates their accuracy against held-out data.
+
+**Remediation**: Implement k-fold cross-validation (k=5) on the real corpus failure dataset. Report precision, recall, and F1-score per error category. Maintain a 20% held-out test set that is never used during training — only for final accuracy measurement.
+
+**Target Metrics** (based on software defect prediction literature):
+- Accuracy: ≥80% (Malhotra, 2015 reports 75-85% for Random Forest on NASA datasets)
+- F1-score: ≥0.75 per category
+- AUC-ROC: ≥0.80
+
+#### Finding F6: No Execution-Based Behavioral Equivalence
+
+**Problem**: No corpus entry is ever *executed*. Correctness is entirely syntactic (string match or lint pass). A transpiled script could be syntactically correct but behaviorally wrong (e.g., an off-by-one in a loop range, incorrect variable scoping, wrong exit code).
+
+**Remediation**: See Section 11.2 for the execution-based oracle design.
+
+---
+
+### 11.2 Execution-Based Oracle Design (Behavioral Equivalence)
+
+The **test oracle problem** (Barr et al., 2015) is the fundamental challenge of determining whether a program's output is correct. For transpilers, the oracle problem is acute: the expected *behavior* of the output program must match the input program's semantics, but behavior is not directly observable from syntax alone.
+
+We propose a **three-tier oracle** that progressively strengthens correctness guarantees:
+
+#### Tier A: Reference Execution Oracle (Differential Testing)
+
+For each corpus entry, maintain a **reference execution trace**:
+
+```toml
+# corpus/tier-2-standard/B-052/execution.toml
+[execution]
+stdin = ""
+argv = []
+env = { HOME = "/tmp/test", PATH = "/usr/bin" }
+
+[expected]
+stdout = "hello world\n"
+stderr = ""
+exit_code = 0
+files_created = ["output.txt"]
+files_content = { "output.txt" = "result\n" }
+```
+
+The transpiled output is executed in an identical sandbox and all observable effects are compared. This is **differential testing** (McKeeman, 1998) where the expected execution trace is the reference oracle.
+
+**Sandbox Requirements**:
+- Filesystem isolation (tmpfs mount, no host access)
+- Network isolation (no outbound connections)
+- Time budget: 5s per entry (kill on timeout)
+- Resource limits: 64MB memory, 1MB stdout
+- Deterministic environment (fixed PATH, HOME, locale, timezone)
+
+#### Tier B: Metamorphic Testing Oracle
+
+**Metamorphic testing** (Chen et al., 2018) alleviates the oracle problem by defining **metamorphic relations** (MRs) — properties that must hold across related inputs, even when individual outputs cannot be independently verified.
+
+**Metamorphic Relations for Shell Transpilation**:
+
+| MR ID | Relation | Description |
+|-------|----------|-------------|
+| MR-1 | **Determinism** | `transpile(X) == transpile(X)` — same input always produces same output |
+| MR-2 | **Monotonicity** | Adding a no-op line to input does not change output semantics |
+| MR-3 | **Commutativity** | Reordering independent variable assignments does not change behavior |
+| MR-4 | **Idempotency** | `transpile(purify(X)) == transpile(X)` — purification is idempotent |
+| MR-5 | **Subsumption** | If `transpile(A)` succeeds and B is a simplification of A, `transpile(B)` must succeed |
+| MR-6 | **Composition** | `transpile(A; B) ≡ transpile(A); transpile(B)` for independent statements |
+| MR-7 | **Negation** | `transpile(if P then A else B)` must swap branches when P is negated |

+> "A central element [of metamorphic testing] is a set of metamorphic relations, which are necessary properties of the target function or algorithm in relation to multiple inputs and their expected outputs." — Chen, T. Y. et al. (2018). "Metamorphic Testing: A Review of Challenges and Opportunities." *ACM Computing Surveys*, 51(1), Article 4.
+
+**Implementation**: For each corpus entry, generate follow-up test cases by applying MR transformations. Verify that the metamorphic relation holds between the source and follow-up outputs. This multiplies the effective corpus size without requiring new expected outputs.
+
+**Coverage Amplification**: 500 corpus entries × 7 MRs = 3,500 effective test cases.
+
+#### Tier C: N-Version Oracle (Cross-Shell Validation)
+
+Execute transpiled POSIX shell output across multiple shell interpreters:
+
+| Shell | Version | Purpose |
+|-------|---------|---------|
+| dash | 0.5.12+ | POSIX reference (strict) |
+| bash | 5.2+ | Most common (permissive) |
+| busybox ash | 1.36+ | Minimal POSIX (embedded) |
+| zsh --emulate sh | 5.9+ | Diversity check |
+
+If all four shells produce identical output, correctness confidence is high. Any divergence indicates either:
+1. A POSIX compliance bug in the transpiled output (the transpiler must be fixed)
+2. A shell interpreter bug (rare, document and exclude)
+
+This follows the **N-version programming** principle (Avizienis, 1985): fault detection through diversity.
+
+> "The N-version programming approach is based on the assumption that the probability of identical errors in independently developed implementations of the same specification is small." — Avizienis, A. (1985). "The N-Version Approach to Fault-Tolerant Software." *IEEE Transactions on Software Engineering*, SE-11(12), 1491-1501.
+
+#### Quantifiable Correctness Metrics
+
+The revised scoring system replaces the current string-containment metric with a multi-dimensional correctness measurement:
+
+| Metric | Formula | Target |
+|--------|---------|--------|
+| **Syntactic Correctness** | `exact_match_count / total_entries` | ≥99% |
+| **Structural Equivalence** | `ast_equivalent_count / total_entries` | ≥99% |
+| **Behavioral Equivalence** | `execution_match_count / executable_entries` | ≥95% |
+| **Metamorphic Consistency** | `mr_hold_count / (entries × mr_count)` | ≥98% |
+| **Cross-Shell Consistency** | `all_shells_agree_count / executable_entries` | ≥90% |
+| **Oracle Precision** | `correct_classifications / total_classifications` | ≥80% |
+| **Oracle Recall** | `detected_faults / total_faults` | ≥85% |
+| **Mutation Kill Rate** | `killed_mutants / total_mutants` | ≥90% |
+
+---
+
+### 11.3 Research Design: Improving Makefile, Bash, and Dockerfile Quality
+
+#### 11.3.1 Bash Quality Improvement
+
+**Current State**: 200 entries (B-001..B-200), 100% convergence, 8 transpiler bugs found and fixed.
+
+**Gap Analysis**:
+1. No execution-based verification — all correctness is syntactic
+2. No coverage of interactive constructs (read, select, trap)
+3. No heredoc/herestring transpilation testing
+4. No pipeline error propagation testing (`set -o pipefail` semantics)
+
+**Research Protocol**:
+
+| Phase | Action | Metric | Target |
+|-------|--------|--------|--------|
+| R1 | Add execution traces for Tier 1-2 entries (90 entries) | Behavioral match rate | ≥95% |
+| R2 | Add metamorphic relations MR-1 through MR-7 | MR violation rate | <2% |
+| R3 | Cross-shell validation (dash, bash, ash, zsh) | Agreement rate | ≥90% |
+| R4 | Add 50 entries for interactive/heredoc/pipeline constructs | Transpilation rate after additions | measure drop |
+| R5 | Train oracle on real B-series failures | Classification F1 | ≥0.75 |
+
+**Bash-Specific Metamorphic Relations**:
+- **MR-B1**: Quoting transformation — `$var` → `"$var"` must not change behavior
+- **MR-B2**: Arithmetic equivalence — `$((x+1))` ≡ `$((x + 1))`
+- **MR-B3**: Function inlining — inlining a single-use function must preserve behavior
+- **MR-B4**: Pipe to process substitution — `cmd1 | cmd2` ≡ `cmd2 <(cmd1)` for stdin readers
+
+#### 11.3.2 Makefile Quality Improvement
+
+**Current State**: 150 entries (M-001..M-150), 100% convergence.
+
+**Gap Analysis**:
+1. No validation of Make's rebuild semantics (timestamp-based dependency resolution)
+2. No testing of parallel make (`-j` flag) safety
+3. No recursive vs non-recursive make pattern testing
+4. No validation of automatic variable expansion (`$@`, `$<`, `$^`, `$?`)
+
+**Research Protocol**:
+
+| Phase | Action | Metric | Target |
+|-------|--------|--------|--------|
+| R1 | Add execution traces with `make -n` dry-run comparison | Command sequence match | ≥98% |
+| R2 | Add parallel-safety test entries (`make -j4` vs `make -j1`) | Output equivalence | ≥95% |
+| R3 | Add 30 entries for automatic variables and pattern rules | Transpilation rate | measure drop |
+| R4 | Validate rebuild semantics (touch file, re-make, verify minimal rebuild) | Correct rebuild count | 100% |
+| R5 | Cross-validate with GNU Make 4.3+ and bmake | Agreement rate | ≥85% |
+
+**Makefile-Specific Metamorphic Relations**:
+- **MR-M1**: Target reordering — reordering independent targets must not change build output
+- **MR-M2**: Variable expansion — `:=` (simply-expanded) must be equivalent to `=` for non-recursive definitions
+- **MR-M3**: Phony equivalence — `.PHONY: clean` must produce same behavior whether declared or not (for recipes without file output)
+
+#### 11.3.3 Dockerfile Quality Improvement
+
+**Current State**: 150 entries (D-001..D-150), 100% convergence.
+
+**Gap Analysis**:
+1. No image build verification (transpiled Dockerfiles are never built)
+2. No layer count optimization measurement
+3. No multi-platform build testing (arm64 vs amd64)
+4. No BuildKit-specific feature testing (cache mounts, secret mounts)
+
+**Research Protocol**:
+
+| Phase | Action | Metric | Target |
+|-------|--------|--------|--------|
+| R1 | Add `docker build --no-cache` verification for Tier 1-2 | Build success rate | ≥95% |
+| R2 | Measure layer count vs expected layer count | Layer count delta | ≤1 per entry |
+| R3 | Add 25 entries for BuildKit features (cache mounts, secrets, heredocs) | Transpilation rate | measure drop |
+| R4 | Hadolint cross-validation (run both bashrs and hadolint, compare) | Agreement rate | ≥90% |
+| R5 | Multi-platform build matrix (amd64, arm64) | Build success rate | ≥90% |
+
+**Dockerfile-Specific Metamorphic Relations**:
+- **MR-D1**: Layer merging — combining two `RUN` commands with `&&` must produce same filesystem
+- **MR-D2**: Stage reordering — reordering independent build stages must produce same final image
+- **MR-D3**: ARG default override — `--build-arg` overriding default must propagate correctly
+
+---
+
+### 11.4 Revised 100-Point Scoring System (v2)
+
+The original scoring system (Section 4) is updated to replace weak metrics with quantifiable measurements:
+
+| Category | v1 (Current) | v2 (Proposed) | Change |
+|----------|-------------|---------------|--------|
+| A. Transpilation Success | 40 pts — transpiles without error | 30 pts — transpiles without error | -10 pts (still critical but overweighted) |
+| B. Output Correctness | 25 pts — `output.contains()` | 25 pts — L1 exact (10) + L2 AST (8) + L3 execution (7) | Decomposed into 3 levels |
+| C. Test Coverage | 15 pts — hardcoded `true` | 15 pts — actual LLVM coverage per entry | Real measurement |
+| D. Lint Compliance | 10 pts — lint pass/fail | 10 pts — lint pass/fail (unchanged) | No change |
+| E. Determinism | 10 pts — transpile twice, compare | 10 pts — transpile twice, compare (unchanged) | No change |
+| **F. Metamorphic Consistency** | — | **5 pts** — MR-1 through MR-7 hold | **NEW** |
+| **G. Cross-Shell Agreement** | — | **5 pts** — all reference shells agree | **NEW** |
+| **Total** | **100 pts** | **100 pts** | Rebalanced |
+
+**v2 Scoring Formula**:
+```
+Score = (A × 30)
+      + (B_L1 × 10 + B_L2 × 8 + B_L3 × 7)
+      + (C_coverage × 15)
+      + (D_lint × 10)
+      + (E_determinism × 10)
+      + (F_metamorphic × 5)
+      + (G_cross_shell × 5)
+```
+
+**Gateway Logic** (updated):
+- If A < 18 (60% transpilation): B through G score 0
+- If B_L1 < 6 (60% exact match): B_L2 and B_L3 score 0
+
+---
+
+### 11.5 Oracle Unification and ML Pipeline
+
+#### 11.5.1 Feature Alignment
+
+The in-tree oracle uses a 73-feature vector (20 lexical + 25 structural + 28 semantic) but only 24 dimensions for k-NN distance calculation. The standalone oracle uses `aprender` with an opaque feature matrix. These must be aligned:
+
+**Unified Feature Schema** (32 features):
+
+| Feature Group | Count | Features |
+|---------------|-------|----------|
+| Lexical | 8 | line_count, token_count, avg_line_length, max_line_length, comment_ratio, blank_ratio, string_literal_count, numeric_literal_count |
+| Structural | 10 | nesting_depth, branch_count, loop_count, function_count, pipe_count, redirect_count, subshell_count, command_count, variable_ref_count, assignment_count |
+| Semantic | 8 | has_shebang, uses_set_e, uses_set_u, has_trap, uses_eval, uses_source, has_heredoc, uses_arithmetic |
+| Quality | 6 | lint_violation_count, lint_severity_max, determinism_score, idempotency_score, quoting_ratio, shellcheck_issue_count |
+
+> **See also**: Section 11.13.3 for full Oracle implementation details (k-NN, Random Forest, feature extraction, drift detection, fix pattern library).
+
+#### 11.5.2 Training Pipeline
+
+```
+Corpus Run (500 entries)
+    │
+    ├── Passing entries → negative examples (no fault)
+    │
+    └── Failing entries → positive examples
+            │
+            ├── Extract 32-feature vector
+            ├── Label: error_category (24 categories)
+            ├── Label: fix_pattern (15 patterns)

+    │  5-Fold CV Report │
+    │  P/R/F1 per class │
+    └─────────────────┘
+```
+
+#### 11.5.3 Drift Detection
+
+Both oracles include drift detection, but they measure different things. Unify on a single drift metric:
+
+```
+drift_score = |accuracy_window_recent - accuracy_window_historical|
+```
+
+Where `accuracy_window_recent` is the classification accuracy over the last 50 corpus runs and `accuracy_window_historical` is the accuracy over the preceding 200 runs. If `drift_score > 0.10` (10% accuracy drop), trigger model retraining.
+
+This follows the concept drift detection methodology from Gama et al. (2014): "A survey on concept drift adaptation."
+

+
+### 11.6 Implementation Roadmap (v2 Enhancements)

+
+**Total estimated effort**: 19 weeks (can be parallelized to ~10 weeks with 2 developers)
+
+---
+
+### 11.7 Aprender Integration: Model Compilation and Provability
+
+The `aprender` crate (../aprender) provides the ML infrastructure for the unified oracle. Key capabilities discovered via `pmat query`:
+
+#### 11.7.1 Core API for Corpus Oracle
+
+**Estimator trait** (`src/traits.rs`):
+```rust
+pub trait Estimator {
+    fn fit(&mut self, x: &Matrix<f32>, y: &Vector<f32>) -> Result<()>;
+    fn predict(&self, x: &Matrix<f32>) -> Vector<f32>;
+    fn score(&self, x: &Matrix<f32>, y: &Vector<f32>) -> f32;
+}
+```
+
+**RandomForestClassifier** (`examples/random_forest_iris.rs`):
+```rust
+let mut rf = RandomForestClassifier::new(100)  // 100 trees
+    .with_max_depth(10)
+    .with_random_state(42);  // deterministic training
+rf.fit(&x_train, &y_train)?;
+let predictions = rf.predict(&x_test);
+let accuracy = rf.score(&x_test, &y_test);
+```
+
+**Classification metrics** (`src/metrics/classification.rs`):
+- `accuracy(y_pred, y_true) -> f32`
+- `precision(y_pred, y_true, Average::Macro) -> f32`
+- `recall(y_pred, y_true, Average::Macro) -> f32`
+- `f1_score(y_pred, y_true, Average::Weighted) -> f32`
+- `evaluate_classification(y_pred, y_true) -> HashMap<String, f32>` — full report
+
+**Cross-validation** (`src/model_selection/mod.rs`):
+- `CrossValidationResult { scores: Vec<f32> }` — k-fold CV
+- `cross_validate(&model, &x, &y, &kfold) -> Result<CrossValidationResult>`
+
+> **See also**: Section 11.13.3 for the Oracle training pipeline that consumes these Aprender APIs.
+
+#### 11.7.2 Poka-Yoke Quality Gates (APR-POKA-001)
+
+Aprender implements Toyota's Poka-yoke (mistake-proofing) as a first-class concept:
+
+**PokaYoke trait** (`src/format/validation.rs`):
+```rust
+pub trait PokaYoke {
+    fn poka_yoke_validate(&self) -> PokaYokeResult;
+    fn quality_score(&self) -> u8 { self.poka_yoke_validate().score }
+}
+```
+
+**Jidoka gate in .apr format** (`src/format/core_io.rs`):
+- `save()` refuses to write models with `quality_score == 0` (APR-POKA-001)
+- Models are serialized as `.apr` files with MessagePack metadata, zstd compression, CRC32 checksums
+- Quality score is embedded in the file header — consumers can verify before loading
+
+**Application to corpus oracle**: The corpus oracle model should implement `PokaYoke` with gates for:
+1. Minimum training accuracy (≥80%)
+2. Minimum F1-score per category (≥0.60)
+3. Training data size (≥50 real failure examples)
+4. Cross-validation score variance (<0.15)
+
+If any gate fails, `save()` refuses to persist the model — Jidoka stops the line at the ML level.
+
+#### 11.7.3 Drift Detection for Oracle Monitoring
+
+Aprender provides two drift detection mechanisms:
+
+**DriftDetector trait** (`src/online/drift.rs`):
+```rust
+pub trait DriftDetector: Send + Sync {
+    fn add_element(&mut self, error: bool);     // feed prediction outcomes
+    fn detected_change(&self) -> DriftStatus;   // check for drift
+}
+```
+
+**RollingDriftMonitor** (`src/metrics/drift.rs`):
+- Maintains reference + current windows
+- Statistical distance measures between windows
+- `RetrainingTrigger`: combines multiple drift signals, requires N consecutive detections
+
+**Application**: After each corpus run, feed oracle classification outcomes into `RollingDriftMonitor`. When drift is detected (corpus failures shift in character), trigger model retraining from updated failure data.
+
+#### 11.7.4 Model Persistence and Versioning
+
+**`.apr` format** (`src/format/core_io.rs`):
+- Binary format: Header (64B) + MessagePack metadata + zstd payload + CRC32
+- AES-256-GCM encryption option for sensitive models
+- Embedded metadata: model type, training date, quality score, feature names
+
+**Corpus oracle model lifecycle**:
+```
+Train on corpus failures → PokaYoke validate → Save as .apr
+    → Embed in bashrs binary (include_bytes!)
+    → Load at runtime for error classification
+    → Monitor with DriftDetector
+    → Retrain when drift detected
+```
+
+---
+
+### 11.8 Formal Schema Enforcement for Output Formats
+
+Each target format (Bash, Makefile, Dockerfile) has a formal grammar or specification that transpiled outputs must conform to. Schema enforcement ensures outputs are not just syntactically plausible but grammatically valid according to the authoritative specification.
+
+#### 11.8.1 POSIX Shell Grammar (Bash Output)
+
+**Authoritative spec**: IEEE Std 1003.1-2017 (POSIX.1), Shell Command Language (Section 2)
+
+**Grammar enforcement layers**:
+
+| Layer | Validator | What It Checks | Pass Criteria |
+|-------|-----------|----------------|---------------|
+| L1: Lexical | bashrs parser (`ShellAst`) | Token stream is valid | Parses without error |
+| L2: Syntactic | `shellcheck -s sh` | POSIX grammar compliance | Zero errors (SC-level "error") |
+| L3: Semantic | bashrs linter (SEC/DET/IDEM rules) | Security, determinism, idempotency | Zero violations |
+| L4: Behavioral | Cross-shell execution (dash, bash, ash) | Runtime equivalence | All shells agree |
+
+**POSIX grammar productions enforced** (subset):
+
+```
+complete_command : list separator_op
+               | list
+               ;
+list            : list separator_op and_or
+               | and_or
+               ;
+and_or          : pipeline
+               | and_or AND_IF linebreak pipeline
+               | and_or OR_IF linebreak pipeline
+               ;
+pipeline        : pipe_sequence
+               | Bang pipe_sequence
+               ;
+```
+
+**Corpus enforcement**: Every transpiled shell script MUST parse successfully against the POSIX grammar. The bashrs parser already produces `ShellAst` — we add a `validate_posix_grammar(ast: &ShellAst) -> Vec<GrammarViolation>` function that checks:
+- No bashisms (process substitution `<()`, arrays, `[[ ]]`)
+- Correct quoting (all variable expansions in double quotes)
+- Valid here-document delimiters
+- Correct `case` pattern syntax
+- Proper arithmetic expansion `$(())`
+
+#### 11.8.2 GNU Make Grammar (Makefile Output)
+
+**Authoritative spec**: GNU Make Manual, 4.4 (2023), Section 3.7 "How `make` Reads a Makefile"
+
+**Grammar enforcement layers**:
+
+| Layer | Validator | What It Checks | Pass Criteria |
+|-------|-----------|----------------|---------------|
+| L1: Lexical | Tab-vs-space detection | Recipe lines use tabs | Zero space-indented recipes |
+| L2: Syntactic | `make -n --warn-undefined-variables` | Valid Make syntax | Zero warnings |
+| L3: Semantic | bashrs Makefile linter (MAKE001-MAKE020) | Best practices | Zero violations |
+| L4: Behavioral | `make -n` dry-run comparison | Command sequence | Matches expected |
+
+**Makefile grammar schema** (key rules):
+
+```
+makefile     : (rule | assignment | directive | comment | empty_line)*
+rule         : targets ':' prerequisites '\n' recipe
+targets      : target (' ' target)*
+prerequisites: prerequisite (' ' prerequisite)*
+recipe       : ('\t' command '\n')+
+assignment   : variable assignment_op value
+assignment_op: ':=' | '?=' | '+=' | '='
+directive    : 'include' | 'ifeq' | 'ifdef' | 'define' | '.PHONY' | ...
+```
+
+**Schema violations detectable at parse time**:
+- Recipe lines not starting with tab character
+- Undefined variable references (`:=` without prior definition)
+- Circular dependency detection
+- `.PHONY` targets with file-producing recipes
+- Recursive vs simply-expanded variable misuse
+
+#### 11.8.3 Dockerfile Grammar (Dockerfile Output)
+
+**Authoritative spec**: Dockerfile reference, Docker Engine v25+ (2024)
+
+**Grammar enforcement layers**:
+
+| Layer | Validator | What It Checks | Pass Criteria |
+|-------|-----------|----------------|---------------|
+| L1: Lexical | Instruction keyword recognition | Valid instructions only | All lines are valid instructions |
+| L2: Syntactic | bashrs Dockerfile parser | Correct argument format | Parses without error |
+| L3: Semantic | bashrs Dockerfile linter (DOCKER001-012) + Hadolint | Best practices | Zero violations |
+| L4: Behavioral | `docker build --no-cache` | Builds successfully | Exit code 0 |
+
+**Dockerfile grammar schema** (key rules):
+
+```
+dockerfile   : (instruction | comment | empty_line)*
+instruction  : FROM from_args
+             | RUN run_args
+             | COPY copy_args
+             | WORKDIR path
+             | ENV env_args
+             | EXPOSE port_spec
+             | USER user_spec
+             | CMD exec_or_shell
+             | ENTRYPOINT exec_or_shell
+             | ARG arg_spec
+             | LABEL label_args
+             | HEALTHCHECK healthcheck_args
+             | ...
+from_args    : ['--platform=' platform] image [':' tag | '@' digest] ['AS' name]
+exec_or_shell: exec_form | shell_form
+exec_form    : '[' string (',' string)* ']'
+shell_form   : string
+```
+
+**Schema violations detectable at parse time**:
+- `FROM` not as first instruction (multi-stage: each stage starts with FROM)
+- `:latest` tag (DOCKER002 — must pin version)
+- Shell form for `ENTRYPOINT`/`CMD` (exec form required)
+- Missing `USER` directive (DOCKER003 — non-root enforcement)
+- `ADD` instead of `COPY` for local files (DOCKER004)
+
+#### 11.8.4 Schema Validation Integration with Corpus Scoring
+
+Add a **Schema Conformance** check to each corpus entry's scoring:
+
+```rust
+fn check_schema_conformance(output: &str, format: CorpusFormat) -> SchemaResult {
+    match format {
+        CorpusFormat::Bash => {
+            let ast = parse_posix_shell(output)?;
+            let violations = validate_posix_grammar(&ast);
+            SchemaResult { valid: violations.is_empty(), violations }
+        }
+        CorpusFormat::Makefile => {
+            let ast = parse_makefile(output)?;
+            let violations = validate_make_grammar(&ast);
+            SchemaResult { valid: violations.is_empty(), violations }
+        }
+        CorpusFormat::Dockerfile => {
+            let ast = parse_dockerfile(output)?;
+            let violations = validate_dockerfile_grammar(&ast);
+            SchemaResult { valid: violations.is_empty(), violations }
+        }
+    }
+}
+```
+
+Schema conformance becomes a **hard gate**: if `valid == false`, the entry scores 0 on categories B through G regardless of other results. This is stronger than the existing gateway logic — a syntactically invalid output cannot be correct, tested, or deterministic.
+
+#### 11.8.5 Aprender Model for Grammar Error Classification
+
+Train a `RandomForestClassifier` via aprender to classify grammar violations by root cause:
+
+| Category | Description | Fix Pattern |
+|----------|-------------|-------------|
+| GRAM-001 | Missing quoting in expansion | Add double quotes around `${}` |
+| GRAM-002 | Bashism in POSIX output | Replace `[[ ]]` with `[ ]` |
+| GRAM-003 | Tab/space confusion in Makefile | Ensure recipe lines use `\t` |
+| GRAM-004 | Shell form in Dockerfile CMD | Convert to exec form `["cmd", "arg"]` |
+| GRAM-005 | Undefined variable reference | Add `:=` assignment before use |
+| GRAM-006 | Invalid POSIX arithmetic | Replace bash-specific `(( ))` with `$(( ))` |
+| GRAM-007 | Missing FROM in Dockerfile | Add `FROM` as first instruction |
+| GRAM-008 | Circular Make dependency | Reorder targets |
+
+The classifier uses the 32-feature unified schema (Section 11.5.1) plus 4 grammar-specific features:
+- `grammar_violation_count`: total violations
+- `grammar_violation_severity`: max severity
+- `format_type`: bash=0, makefile=1, dockerfile=2
+- `nesting_at_violation`: AST depth at first violation
+
+Training data comes from real corpus grammar failures, following the same pipeline as Section 11.5.2. The model is persisted as `.apr` with Poka-yoke validation (APR-POKA-001) ensuring minimum quality before deployment.
+
+### 11.9 OIP-Driven Corpus Generation
+
+Organizational Intelligence Platform (OIP) provides automated mining of real fix patterns from git history across an entire GitHub organization. This section defines how OIP outputs are systematically converted into corpus entries, ensuring the corpus reflects **real defects** rather than hypothetical edge cases.
+
+#### 11.9.1 Mining Methodology
+
+OIP analyzes commit history to classify fix patterns into 18 defect categories:
+
+```bash
+# Extract training data from a single repo
+oip extract-training-data --repo . --max-commits 500
+
+# Analyze an entire GitHub organization
+oip analyze --org paiml
+
+# Output: classified fix commits with defect categories, severity, and code diffs
+```
+
+**Key insight**: Every bug fix in the transpiler's history represents a real-world failure mode. Each fix should generate 1-3 corpus entries that would **catch the regression** if the bug were reintroduced.
+
+#### 11.9.2 Defect Category to Corpus Entry Mapping
+
+OIP's 18 defect categories map to specific corpus entry patterns:
+
+| OIP Category | Frequency (bashrs) | Corpus Entry Pattern | Example |
+|---|---|---|---|
+| ASTTransform | 62 | Parser/emitter correctness: heredoc, brackets, brace groups, command substitution | B-321..B-330 |
+| OperatorPrecedence | 6 | Arithmetic parenthesization, operator associativity | B-331..B-335 |
+| SecurityVulnerabilities | 24 | Quoting, injection prevention, special character handling | B-336..B-340 |
+| IdempotencyViolation | 8 | `mkdir -p`, atomic writes, lock files, existence checks | B-341..B-345 |
+| ComprehensionBugs | 8 | Iterator patterns, accumulation, filtering, early exit | B-346..B-350 |
+| ConfigurationErrors | 7 | Env var handling, default values, path construction | Future entries |
+| IntegrationFailures | 3 | Cross-shell compatibility, version-specific behavior | Future entries |
+| FalsePositives | 5 | Linter rules triggering on valid code (SC2171, MAKE016) | Linter corpus |
+
+#### 11.9.3 Fix-Driven Entry Generation Protocol
+
+For each OIP-detected fix commit:
+
+1. **Extract the fix diff**: Identify what changed in the transpiler
+2. **Identify the input that triggered the bug**: Reconstruct the Rust DSL input
+3. **Determine the correct output**: What the transpiler should produce post-fix
+4. **Create 1-3 corpus entries**:
+   - **Entry A**: The exact regression case (minimal reproducer)
+   - **Entry B**: A generalized variant (different values, same pattern)
+   - **Entry C**: An edge case variant (boundary conditions)
+
+**Example** (from Issue #59 — nested quotes in command substitution):
+
+```
+Fix commit: "fix: handle nested quotes inside command substitution"
+OIP category: ASTTransform
+Severity: P1
+
+→ Corpus entry B-321:
+  Input:  fn main() { let out = command_output("echo \"hello\""); }
+  Output: out=$(echo "hello")
+  Tests:  Nested quoting preserved through transpilation
+```
+
+#### 11.9.4 Org-Wide Pattern Analysis
+
+Running `oip analyze --org paiml` across 28 repositories reveals cross-project defect patterns applicable to bashrs:
+
+| Cross-Project Pattern | Source Repos | bashrs Relevance |
+|---|---|---|
+| Off-by-one in range iteration | depyler, aprender | `for i in $(seq)` boundary values |
+| String escaping in code generation | depyler, decy | Quote handling in shell output |
+| Precedence errors in expression trees | depyler, decy | Arithmetic parenthesization |
+| Missing error path handling | trueno, aprender | Shell `set -e` interaction |
+
+These patterns inform corpus entries that test **cross-cutting concerns** — defect classes that appear in multiple transpiler projects and are likely to recur.
+
+#### 11.9.5 Continuous OIP Integration
+
+OIP analysis should be re-run periodically to discover new fix patterns:
+
+- **Per-release**: `oip extract-training-data --repo . --since <last-release-tag>`
+- **Monthly**: `oip analyze --org paiml` for cross-project patterns
+- **On regression**: Immediate `oip extract-training-data` on the fix commit to generate corpus entries
+
+Each OIP run produces a training data file (JSON) that is processed into corpus entries following the protocol in Section 11.9.3. The corpus grows monotonically (Section 1.2 — append-only rule) with each OIP cycle adding 10-30 entries.
+
+### 11.10 Cross-Project Techniques from depyler
+
+The `depyler` Python-to-Rust transpiler (same org) has developed three corpus-driven ML techniques that are directly applicable to bashrs. This section defines how each technique adapts to shell transpilation.
+
+> "Standing on the shoulders of sister projects is not reuse—it is organizational learning." — Adapted from Nonaka & Takeuchi (1995), *The Knowledge-Creating Company*.
+
+#### 11.10.1 Tarantula Fault Localization for Transpiler Decisions
+
+**Source**: `depyler-oracle/src/tarantula_corpus.rs` (Jones & Harrold, 2005)
+
+Tarantula assigns a **suspiciousness score** to each transpiler decision based on how strongly it correlates with corpus failures. In depyler, this identified `async_await` as the #1 priority (suspiciousness 0.946) when intuition suggested other features.
+
+> **See also**: Section 11.13.2 for the implemented SBFL module (`rash/src/quality/sbfl.rs`) with 5 formulas and 16+ tests.
+
+**Adaptation to bashrs**:
+
+Each corpus entry's transpilation produces a **decision trace** — the sequence of emitter choices made:
+
+```rust
+struct TranspilerDecision {
+    /// e.g., "emit_for_range", "emit_if_condition", "emit_arithmetic"
+    decision_type: String,
+    /// e.g., "seq_inclusive", "test_bracket", "dollar_paren_paren"
+    choice: String,
+    /// Line in the Rust DSL input
+    source_span: (usize, usize),
+}
+```
+
+Tarantula scoring formula (Jones & Harrold, 2005):
+
+```
+suspiciousness(d) = (failed(d) / total_failed) / ((failed(d) / total_failed) + (passed(d) / total_passed))
+```
+
+Where `failed(d)` = number of failing corpus entries that exercised decision `d`, and `passed(d)` = number of passing entries that exercised it.
+
+**Expected output** (run periodically on corpus):
+
+```
+Decision                    Suspiciousness   Impact    Priority
+────────────────────────────────────────────────────────────────
+emit_nested_arithmetic      0.89             HIGH      Fix first
+emit_string_in_conditional  0.72             MEDIUM    Fix second
+emit_heredoc_expansion      0.68             MEDIUM    Investigate
+emit_brace_group            0.45             LOW       Monitor
+emit_simple_assignment      0.02             NONE      Stable
+```
+
+Decisions with suspiciousness > 0.7 trigger automatic corpus entry generation (Section 11.9.3) targeting the suspicious code path with adversarial inputs.
+
+#### 11.10.2 CITL (Compiler-in-the-Loop) Pattern Mining
+
+**Source**: `depyler-oracle/src/corpus_citl.rs` (entrenar `DecisionCITL`)
+
+CITL closes the feedback loop between transpiler output and downstream validation. In depyler, the "compiler" is `rustc` — transpiled Rust that fails `cargo check` generates training signal. In bashrs, the "compilers" are **shellcheck** and **/bin/sh execution**.
+
+**CITL feedback loop for bashrs**:
+
+```
+┌────────────────────┐     ┌──────────────────┐     ┌────────────────────┐

+                                                 └──────────────────┘
+```
+
+**Pattern store schema**:
+
+```rust
+struct ShellFixPattern {
+    /// Shellcheck error code or execution failure type
+    error_signal: String,        // e.g., "SC2086", "B3_timeout", "G_dash_fail"
+    /// Transpiler decision that caused the error
+    causal_decision: String,     // e.g., "emit_unquoted_variable"
+    /// Fix applied to the transpiler
+    fix_type: String,            // e.g., "add_double_quotes"
+    /// Confidence (0.0-1.0) from Tarantula suspiciousness
+    confidence: f64,
+    /// Corpus entries that demonstrated this pattern
+    evidence_ids: Vec<String>,   // e.g., ["B-042", "B-189", "B-336"]
+}
+```
+
+**Training cycle**:
+
+1. Run full corpus → collect all B3/D/G failures
+2. Extract decision traces from failing entries
+3. Match failure signals to decisions via Tarantula (Section 11.10.1)
+4. Build `ShellFixPattern` entries for each error→decision→fix triple
+5. On next transpilation, query PatternStore for known fixes when a decision is about to be made
+6. Log suggestions to convergence log for human review
+
+#### 11.10.3 Graph-Aware Corpus with Call Context
+
+**Source**: `depyler-oracle/src/graph_corpus.rs` (depyler-graph `VectorizedFailure`)
+
+Depyler enriches each corpus failure with **call graph context** — the in-degree, out-degree, callers, and callees of the function where the failure occurred. Functions with high connectivity (many callers) are higher priority because a fix has greater blast radius.
+
+**Adaptation to bashrs**:
+
+The Rust DSL inputs define functions. Each corpus entry can be enriched with graph context:
+
+```rust
+struct ShellGraphContext {
+    /// Function being transpiled
+    function_name: String,
+    /// Number of call sites in the corpus (how many entries call this function)
+    corpus_call_count: usize,
+    /// Functions this function calls
+    callees: Vec<String>,
+    /// Functions that call this function
+    callers: Vec<String>,
+    /// Whether this function is in the "hot path" (called by >5 entries)
+    is_high_connectivity: bool,
+}
+```
+
+**Prioritization formula**:
+
+```
+priority(f) = suspiciousness(f) × log2(1 + corpus_call_count(f))
+```
+
+A function that is both suspicious (high failure correlation) AND highly connected (many callers) gets top priority. This prevents fixing obscure one-off patterns when high-impact shared functions have bugs.
+
+**Example application**:
+
+| Function | Suspiciousness | Call Count | Priority | Action |
+|----------|---------------|------------|----------|--------|
+| `emit_arithmetic` | 0.89 | 45 | 4.94 | Fix immediately |
+| `emit_for_range` | 0.72 | 38 | 3.97 | Fix next |
+| `emit_heredoc` | 0.68 | 3 | 1.36 | Defer |
+| `emit_assignment` | 0.02 | 120 | 0.14 | Stable |
+
+#### 11.10.4 Weak Supervision and Error Deduplication
+
+**Source**: `depyler-oracle/src/corpus_extract.rs`
+
+Depyler deduplicates training errors by hashing `(error_code, message)` and tracks extraction cycles. This prevents the same shellcheck warning from inflating training data.
+
+**Adaptation to bashrs**:
+
+```rust
+struct ShellTrainingError {
+    /// Shellcheck code or execution failure type
+    error_code: String,
+    /// Error message (normalized — paths and line numbers stripped)
+    message: String,
+    /// Deduplication hash
+    hash: u64,
+    /// Which corpus run discovered this error
+    cycle: u32,
+    /// Risk classification (programmatic labeling)
+    risk: RiskLevel,  // HIGH, MEDIUM, LOW
+}
+
+enum RiskLevel {
+    /// Security-relevant (injection, unquoted expansion in eval)
+    High,
+    /// Correctness-relevant (wrong output, behavioral mismatch)
+    Medium,
+    /// Style/lint (shellcheck warnings that don't affect behavior)
+    Low,
+}
+```
+
+**Programmatic labeling rules** (weak supervision à la Snorkel, Ratner et al. 2017):
+
+| Rule | Condition | Label |
+|------|-----------|-------|
+| SEC_RULE | error_code matches SEC001-SEC008 | HIGH |
+| B3_FAIL | entry has B3 behavioral failure | HIGH |
+| G_FAIL | entry has cross-shell disagreement (sh vs dash) | MEDIUM |
+| LINT_ONLY | only shellcheck style warnings, B3 passes | LOW |
+| QUOTING | error_code is SC2086 (unquoted variable) | MEDIUM |
+
+This automated triage ensures fix effort is directed at high-risk failures first, following the Pareto principle (Juran, 1951): 80% of user-visible defects come from 20% of error categories.
+
+#### 11.10.5 Multi-Corpus Convergence Dashboard
+
+**Source**: depyler `improve-converge.md` (17 iterations tracked)
+
+Depyler tracks per-tier compile rates across 5 independent corpora at each iteration, with root cause analysis tables. Bashrs should adopt the same granular tracking.
+
+**Proposed convergence table format**:
+
+| Iteration | Date | Bash (350) | Makefile (150) | Dockerfile (150) | Total | Score | Notes |
+|-----------|------|-----------|---------------|------------------|-------|-------|-------|
+| 14 | 2026-02-07 | 349/350 | 150/150 | 150/150 | 649/650 | 99.9 | B-143 only failure |
+| 15 | 2026-02-08 | 349/350 | 150/150 | 150/150 | 649/650 | 99.9 | +30 OIP entries |
+| 16 | TBD | ? | ? | ? | ? | ? | CITL-driven entries |
+
+Each iteration records:
+- **Per-format pass rates** (not just aggregate)
+- **New entries added** (append-only count)
+- **Failures fixed** (transpiler changes)
+- **Root cause** for any new failures introduced
+
+This enables detection of **format-specific regressions** — a Makefile fix that accidentally breaks Bash entries would be immediately visible.
+
+#### 11.10.6 Implementation Roadmap
+
+| Phase | Technique | Effort | Prerequisite | Expected Impact |
+|-------|-----------|--------|-------------|-----------------|
+| 1 | Error deduplication + weak supervision (11.10.4) | 1 week | None | Prioritized fix backlog |
+| 2 | Decision tracing in emitter (11.10.1 prerequisite) | 2 weeks | None | Enables Tarantula + CITL |
+| 3 | Tarantula fault localization (11.10.1) | 1 week | Phase 2 | Data-driven prioritization |
+| 4 | CITL pattern store (11.10.2) | 2 weeks | Phases 2-3 | Automated fix suggestions |
+| 5 | Graph-aware prioritization (11.10.3) | 1 week | Phase 3 | Impact-weighted triage |
+| 6 | Convergence dashboard (11.10.5) | 3 days | None | Regression visibility |
+
+Phase 1 and Phase 6 are independent and can start immediately. Phases 2-5 are sequential.
+
+### 11.11 Domain-Specific Corpus Categories
+
+The corpus must cover three domain-specific categories that standard tier progression misses. These represent real-world usage patterns where shell scripts are most commonly written and maintained, and where transpiler correctness has the highest practical impact.
+
+#### 11.11.1 Category A: Shell Configuration Files (bashrc/zshrc/profile)
+
+**Motivation**: Shell config files (`.bashrc`, `.zshrc`, `.profile`, `/etc/environment`) are the most-edited shell scripts in existence. Every developer maintains at least one. They have unique patterns:
+
+- **PATH manipulation**: Append/prepend directories, deduplication, conditional addition
+- **Alias definitions**: Simple and complex aliases with quoting challenges
+- **Environment exports**: `export VAR=value` chains, conditional exports
+- **Prompt customization**: PS1/PS2 with escape sequences and dynamic content
+- **Conditional tool setup**: `if command -v tool >/dev/null; then ... fi`
+- **Source/dot inclusion**: `. ~/.bashrc.d/*.sh` sourcing patterns
+- **Shell options**: `set -o`, `shopt -s`, `setopt` configuration
+- **History configuration**: HISTSIZE, HISTFILESIZE, HISTCONTROL
+
+**Corpus Entry Pattern**: Rust DSL representing config-style shell constructs. The transpiler should emit clean, idempotent config blocks suitable for inclusion in rc files.
+
+**Unique Quality Requirements**:
+- **Idempotent**: Sourcing the config twice must be safe (no duplicate PATH entries)
+- **Non-destructive**: Config blocks must not overwrite user state (use `${VAR:-default}`)
+- **POSIX-portable**: Must work when sourced by sh, bash, zsh, and dash
+
+**Entry Range**: B-371..B-380
+
+#### 11.11.2 Category B: Shell One-Liners (bash/sh/zsh)
+
+**Motivation**: Shell one-liners are the most common ad-hoc shell usage. They compress complex operations into single pipeline expressions. The transpiler must produce output that captures the *intent* of these patterns even when the Rust DSL input is multi-statement.
+
+**Key Patterns**:
+- **Pipeline chains**: `cmd1 | cmd2 | cmd3` — data flows through filters
+- **Find-exec patterns**: `find . -name '*.log' -exec rm {} \;`
+- **Xargs composition**: `cmd | xargs -I{} other {}`
+- **Process substitution**: `diff <(cmd1) <(cmd2)`
+- **Inline conditionals**: `test -f file && source file`
+- **Redirect chains**: `cmd > out 2>&1`, `cmd 2>/dev/null`
+- **Sort-uniq pipelines**: `cmd | sort | uniq -c | sort -rn | head`
+- **Awk/sed transforms**: Text processing in single expressions
+- **Subshell grouping**: `(cd dir && cmd)` to avoid directory pollution
+- **Arithmetic expansion**: Complex `$((...))` expressions
+
+**Corpus Entry Pattern**: Rust DSL that expresses operations typically solved by one-liners. The transpiled output should demonstrate that the transpiler can produce compact, idiomatic shell.
+
+**Unique Quality Requirements**:
+- **Behavioral equivalence**: The multi-statement Rust DSL must produce shell output that achieves the same result as the canonical one-liner
+- **Pipeline safety**: No unquoted variables in pipe chains
+- **Error propagation**: `set -o pipefail` equivalent semantics where applicable
+
+**Entry Range**: B-381..B-390
+
+#### 11.11.3 Category C: Provability Corpus (Restricted Rust → Verified Shell)
+
+**Motivation**: The provability corpus contains entries where the Rust source is **restricted to a formally verifiable subset** — pure functions, no I/O, no unsafe, no panics. This subset can be:
+
+1. **Verified by Miri**: Rust's mid-level IR interpreter can prove absence of undefined behavior
+2. **Verified by property tests**: Exhaustive/random testing over the input domain
+3. **Verified by symbolic execution**: For simple arithmetic, the Rust and shell outputs can be proven equivalent
+
+**Restricted Rust Subset** (allowed constructs):
+- Pure functions (`fn f(x: i32) -> i32`)
+- Integer arithmetic (`+`, `-`, `*`, `/`, `%`)
+- Boolean logic (`&&`, `||`, `!`)
+- Conditionals (`if`/`else`)
+- Bounded loops (`for i in 0..n`, `while i < n`)
+- Local variables only (no globals, no statics, no heap)
+- No I/O, no `println!`, no `eprintln!`
+- No `unsafe`, no `unwrap`, no `expect`, no `panic!`
+
+**Provability Chain**:
+```
+Rust source (restricted subset)
+  │
+  ├── Miri verification: cargo miri run (proves no UB)
+  ├── Property test: proptest over input domain
+  │
+  ▼
+Shell output (transpiled)
+  │
+  ├── Behavioral test: sh -c "$script" produces same result
+  ├── Cross-shell: sh, dash, bash agree
+  │
+  ▼
+Equivalence: Rust output ≡ Shell output (for all tested inputs)
+```
+
+**Why This Matters**: The provability corpus establishes a **trusted kernel** — a set of entries where correctness is not just tested but *proven*. This kernel serves as the foundation for confidence in the transpiler. If the transpiler is correct on provably-correct Rust, we have high confidence it's correct on general Rust.
+
+**Corpus Entry Pattern**: Pure Rust functions with known-correct outputs. Expected shell output is derived from the Rust semantics (not observed from the transpiler). This makes the corpus truly **falsifying** — it can catch transpiler bugs that other entries cannot.
+
+**Unique Quality Requirements**:
+- **Miri-clean**: `cargo miri run` passes on the Rust source (no UB)
+- **Deterministic**: Pure functions produce identical output every run
+- **Exhaustively testable**: Small input domains allow full enumeration
+- **No shell-isms**: Output must not rely on shell-specific behavior (e.g., string-as-boolean)
+
+**Entry Range**: B-391..B-400
+
+#### 11.11.4 Category D: Unix Tool Patterns
+
+**Motivation**: Unix tools (`awk`, `sed`, `find`, `grep`, `cut`, `sort`, `uniq`, `tr`, `tee`, `wc`, `xargs`, `tar`, `curl`) are the building blocks of shell scripting. Real-world shell scripts overwhelmingly consist of orchestrating these tools together. The transpiler must produce output that correctly models the *setup, invocation, and result capture* patterns these tools require.
+
+**Key Patterns**:
+- **Variable-driven tool invocation**: Building command arguments from variables
+- **Result capture**: Capturing tool output into variables for downstream use
+- **Flag/option construction**: Building option strings conditionally
+- **Path manipulation**: Constructing paths for `find`, `tar`, `rsync` targets
+- **Threshold/limit configuration**: Setting numeric limits for `head`, `tail`, `wc`
+- **Pattern construction**: Building regex/glob patterns for `grep`, `find`, `awk`
+- **Multi-tool coordination**: Setting up shared state across tool invocations (temp dirs, log files)
+- **Cleanup patterns**: Trap-based cleanup of temp files created by tool pipelines
+
+**Unique Quality Requirements**:
+- **Tool-safe quoting**: Variables used as tool arguments must be properly quoted
+- **Exit code awareness**: Tool failure must not silently propagate
+- **Temp file hygiene**: Any temp files must be cleaned up via trap
+
+**Entry Range**: B-401..B-410
+
+#### 11.11.5 Category E: Language Integration One-Liners
+
+**Motivation**: Shell scripts frequently orchestrate other language runtimes — compiling C, running Python scripts, invoking Perl/Ruby/Node one-liners, managing virtual environments, and piping between languages. These cross-language patterns are among the most error-prone shell constructs because they involve quoting across language boundaries.
+
+**Key Patterns**:
+- **C compilation**: `gcc -o bin src.c -lm`, conditional flags, multi-file compilation
+- **Python invocation**: `python3 -c '...'`, venv activation, pip install chains
+- **Perl one-liners**: `perl -ne '...'`, `-pi -e` in-place editing
+- **Ruby scripting**: `ruby -e '...'`, gem management
+- **Node.js**: `node -e '...'`, npm/npx invocation
+- **Build system orchestration**: `cmake && make`, `cargo build`, `go build`
+- **Language version management**: Checking version, conditional on runtime availability
+- **Cross-language piping**: Output from one language runtime piped to another
+
+**Unique Quality Requirements**:
+- **Nested quoting correctness**: Shell quotes wrapping language-specific quotes must not collide
+- **Runtime availability check**: Should guard with `command -v` or equivalent
+- **Exit code propagation**: Language runtime failures must surface to shell
+
+**Entry Range**: B-411..B-420
+
+#### 11.11.6 Category F: System Tooling (cron, startups, daemons)
+
+**Motivation**: System administration scripts handle cron jobs, service management, init scripts, log rotation, scheduled tasks, and daemon lifecycle. These are the highest-stakes shell scripts — they run unattended, often as root, and failures may go unnoticed for days. Correctness is paramount.
+
+**Key Patterns**:
+- **Cron job setup**: Minute/hour/day fields, PATH setting, output redirection
+- **Service management**: Start/stop/restart/status/enable patterns
+- **Init script structure**: LSB header, start/stop functions, PID files
+- **Log rotation**: Size-based rotation, retention count, compression
+- **Health monitoring**: Periodic health checks with alerting thresholds
+- **Backup scripts**: Source/destination, retention, compression, verification
+- **Scheduled maintenance**: Database vacuum, cache cleanup, temp file pruning
+- **Daemon lifecycle**: Daemonize, PID file, signal handling, graceful shutdown
+
+**Unique Quality Requirements**:
+- **Idempotent**: System scripts MUST be safe to re-run (restart already-running, create already-existing)
+- **Fail-safe**: Errors must be logged, not silently swallowed
+- **Root-safe**: No assumptions about user; explicit permission checks where needed
+- **Signal-aware**: Trap handlers for SIGTERM/SIGINT for graceful shutdown
+
+**Entry Range**: B-421..B-430
+
+#### 11.11.7 Category G: Unix Tool Reimplementation (Transpiled Coreutils)
+
+**Motivation**: The ultimate test of a Rust-to-shell transpiler is whether it can reimplement Unix coreutils. This category takes the **top 30 Unix tools**, writes their core algorithms in Rust, transpiles to POSIX shell, and verifies **1:1 behavioral parity** with the original tools.
+
+This is not a toy exercise. The Unix philosophy of small, composable tools maps directly to the transpiler's strength: each tool is a self-contained pure function operating on integers, strings, and simple control flow. If the transpiler can faithfully reproduce the algorithms of `seq`, `factor`, `wc`, `sort`, `uniq`, `tr`, `basename`, and `expr`, it proves the transpiler is correct for the computational core of shell scripting.
+
+**The 30 Tools** (grouped by algorithm complexity):
+
+| Group | Tools | Algorithm Pattern |
+|-------|-------|-------------------|
+| **Trivial** (exit/print) | `true`, `false`, `echo`, `yes`, `printf`, `seq` | Constants, loops, formatted output |
+| **Arithmetic** | `expr`, `factor`, `seq`, `test` | Integer arithmetic, prime decomposition, comparisons |
+| **String** | `basename`, `dirname`, `rev`, `tr`, `wc`, `nl` | Character iteration, counting, transformation |
+| **Set/Filter** | `uniq`, `sort`, `head`, `tail`, `cut`, `fold` | Deduplication, ordering, selection, wrapping |
+| **File/Compose** | `cat`, `tac`, `tee`, `paste`, `comm`, `join`, `expand` | Passthrough, reversal, merge, comparison |
+| **System** | `sleep`, `env`, `id` | Timing, environment, identity |
+
+**Implementation Approach**:
+
+Each entry implements the **core algorithm** of the tool in Rust DSL:
+
+```rust
+// Example: factor(n) — prime factorization
+fn factor(n: i32) -> i32 {
+    let mut num = n;
+    let mut divisor = 2;
+    while divisor * divisor <= num {
+        while num % divisor == 0 {
+            num = num / divisor;
+            divisor += 1; // simplified: tracks last factor
+        }
+        divisor += 1;
+    }
+    num // returns largest prime factor
+}
+```
+
+Transpiles to:
+```sh
+factor() {
+    num="$1"
+    divisor='2'
+    while [ $((divisor * divisor)) -le "$num" ]; do
+        while [ $((num % divisor)) -eq 0 ]; do
+            num=$((num / divisor))
+            divisor=$((divisor + 1))
+        done
+        divisor=$((divisor + 1))
+    done
+    echo "$num"
+}
+```
+
+**Verification Protocol** (1:1 Parity):
+
+For each reimplemented tool, verify:
+
+1. **Algorithm correctness**: The Rust source produces correct results (unit tests + property tests)
+2. **Transpilation fidelity**: The transpiled shell implements the same algorithm
+3. **Behavioral equivalence**: For a test vector of inputs, `tool_rust(input) == tool_shell(input)`
+4. **Cross-shell agreement**: Output is identical in sh, bash, and dash
+5. **Shellcheck clean**: Transpiled output passes `shellcheck -s sh`
+
+```
+For each tool T in {true, false, echo, seq, factor, ...}:
+  1. Write T_rust: fn T(args) -> output  [Rust DSL]
+  2. Transpile: T_shell = transpile(T_rust)  [POSIX sh]
+  3. For each test_input in test_vectors(T):
+       assert T_rust(test_input) == T_shell(test_input)
+  4. assert shellcheck(T_shell) == PASS
+  5. assert T_shell(sh) == T_shell(dash) == T_shell(bash)
+```
+
+**Why 1:1 Parity Matters**: If we can prove that `factor_rust(n) == factor_shell(n)` for all `n` in a test domain, and the Rust source is verified by Miri/property tests, then we have a **proof chain** from Rust correctness to shell correctness. This is the provability corpus (Category C) applied to real-world tools.
+
+**Entry Range**: B-431..B-460
+
+**Future Work**: As the transpiler gains support for stdin/stdout piping, string slicing, and file I/O, these entries can evolve from core-algorithm-only to full tool reimplementations with flag parsing and I/O handling.
+
+#### 11.11.8 Category H: Regex Pattern Corpus (Pattern Matching → Shell)
+
+**Motivation**: Regular expressions are fundamental to shell scripting — `grep`, `sed`, `awk`, `find`, and `[[ =~ ]]` all rely on regex. The transpiler must correctly translate Rust-style pattern matching logic into equivalent POSIX shell constructs (case/esac, grep patterns, character class tests, string prefix/suffix operations). This category exercises the transpiler's ability to handle:
+
+1. **Character classification** — digit, alpha, alnum, space detection via shell `case` or `[ ]` tests
+2. **Pattern matching semantics** — glob patterns, case/esac branches, prefix/suffix stripping
+3. **Finite automaton simulation** — state machines transpiled to shell loops with case dispatch
+4. **Quantifier logic** — greedy/lazy matching simulated through loop bounds and counters
+5. **Alternation and grouping** — multiple pattern branches, nested match logic
+6. **Anchoring** — start-of-string, end-of-string, whole-string matching via shell parameter expansion
+
+**Design Constraints** (Rust DSL subset):
+- No actual `regex` crate — all patterns are simulated via integer arithmetic, boolean logic, and control flow
+- Character codes represented as integers (e.g., 48-57 for digits, 65-90 for uppercase)
+- Pattern state encoded as integer variables (0=no match, 1=matching, 2=matched)
+- Quantifiers simulated via bounded while loops with counters
+- Alternation via nested if/else chains
+
+**Entry Groups** (30 entries: B-461..B-490):
+
+| Group | Entries | Pattern | Shell Construct |
+|-------|---------|---------|-----------------|
+| Character Classes | B-461..B-465 | `[0-9]`, `[a-z]`, `[A-Z]`, `\s`, `\w` | Integer range checks |
+| Quantifiers | B-466..B-470 | `+`, `*`, `?`, `{n}`, `{n,m}` | Bounded while loops |
+| Anchoring | B-471..B-475 | `^`, `$`, `\b`, `^...$` | Prefix/suffix position checks |
+| Alternation | B-476..B-480 | `a|b`, `(foo|bar)`, nested | If/else chains |
+| State Machines | B-481..B-485 | NFA/DFA simulation | Case dispatch in while loop |
+| Composition | B-486..B-490 | Combined patterns | Multi-function pipelines |
+
+**Verification Protocol**:
+1. Each entry must transpile to valid POSIX shell
+2. Pattern matching logic must produce correct accept/reject decisions
+3. State machine entries must terminate (bounded loops, no infinite states)
+4. All entries must be deterministic (same input → same match result)
+5. Cross-shell agreement: sh and dash must produce identical match results
+
+**Entry Range**: B-461..B-490

+
+### 11.13 ML-Powered Linting, Error Classification, and Rich Reporting
+
+**Status**: Implemented (2025-12-07)
+**Source**: Merged from BASHRS-SPEC-ML-001 v1.0.0
+
+> This section consolidates the standalone ML linting specification into the unified corpus spec. All 5 phases (17 tasks) are implemented and verified in the codebase. Cross-references to related sections are provided throughout.
+
+#### 11.13.1 Overview and Toyota Way Alignment
+
+ML-powered linting enhances bashrs diagnostics with intelligent error classification, spectrum-based fault localization, and rich visual reporting. The motivation: raw lint output (e.g., 47 individual diagnostics) overwhelms users. ML clustering reduces this to 3 actionable clusters with confidence scores and auto-fix suggestions, following the Pareto principle (Juran, 1951).
+
+**Toyota Way mapping**:
+
+| Principle | Application |
+|---|---|
+| **Jidoka** | ML classifies errors but human approves fixes |
+| **Genchi Genbutsu** | SBFL locates actual fault locations in code |
+| **Kaizen** | Oracle learns from user fix acceptance |
+| **Heijunka** | Cluster errors to batch similar fixes |
+| **Visual Management** | Rich ASCII dashboards and sparklines (see Section 11.12) |
+| **Andon** | Color-coded severity with visual hierarchy |
+| **Poka-yoke** | Confidence scores prevent bad auto-fixes |
+| **Nemawashi** | CITL export enables team review |
+
+**Cross-references**: Quality gate configuration in Section 9; Oracle unification in Section 11.5; Aprender integration in Section 11.7.
+
+#### 11.13.2 Tarantula SBFL Fault Localization (Implemented)
+
+Spectrum-Based Fault Localization (SBFL) ranks code locations by suspiciousness — code executed more by failing tests than passing tests is more likely to contain bugs (Jones & Harrold, 2005 [26]; Abreu et al., 2009 [33]).
+
+**Data structures**: `StatementId` (file, line, column, rule_code), `StatementCoverage` (passed/failed execution counts), `SuspiciousnessRanking` (rank, score, explanation).
+
+**Formulas** (5 supported via `SbflFormula` enum):
+
+| Formula | Definition | Use Case |
+|---|---|---|
+| Tarantula | `(f/F) / ((f/F) + (p/P))` | General-purpose, interpretable |
+| Ochiai | `f / sqrt(F × (f + p))` | Often superior accuracy |
+| DStar | `f^* / (p + (F - f))` | Configurable exponent |
+| Jaccard | `f / (F + p)` | Set-similarity based |
+| Wong2 | `f - p` | Simple difference |
+
+Where `f` = failed executions of statement, `p` = passed executions, `F` = total failed tests, `P` = total passed tests.
+
+**API**: `localize_faults(diagnostics, test_results) -> Vec<SuspiciousnessRanking>` — groups diagnostics by rule code, applies SBFL, returns top-N most suspicious.
+
+**Implementation**: `rash/src/quality/sbfl.rs` (`FaultLocalizer`, 16+ tests).
+
+**Cross-reference**: Decision tracing context in Section 11.10.1.
+
+#### 11.13.3 Oracle ML-Powered Error Classifier (Implemented)
+
+The Oracle classifies shell script errors into 15 categories using a multi-model architecture: feature extraction → k-NN + Random Forest → pattern library.
+
+**Error categories** (`ShellErrorCategory` enum, 15 variants):
+- Security: `CommandInjection`, `PathTraversal`, `UnsafeExpansion`
+- Determinism: `NonDeterministicRandom`, `TimestampUsage`, `ProcessIdDependency`
+- Idempotency: `NonIdempotentOperation`, `MissingGuard`, `UnsafeOverwrite`
+- Quoting: `MissingQuotes`, `GlobbingRisk`, `WordSplitting`
+- Other: `SyntaxError`, `StyleViolation`, `Unknown`
+
+**Feature extraction**: 73-feature `FeatureVector` (20 lexical + 25 structural + 28 semantic) extracted from each diagnostic and its source context. The unified feature schema (Section 11.5.1) aligns the in-tree 73-feature vector with the standalone oracle's opaque matrix via a 32-feature common schema.
+
+**Classifiers**:
+- **k-NN** (k=5, online, fast): `rash/src/quality/oracle.rs` (`KnnClassifier`, 14+ tests)
+- **Random Forest** (100 trees, batch, accurate): `bashrs-oracle/src/lib.rs` (via `aprender` — see Section 11.7)
+- **Keyword fallback**: `bashrs-oracle/src/classifier.rs` (`ErrorClassifier`)
+- **Ensemble**: Weighted majority vote combining k-NN and Random Forest
+
+**Drift detection**: `DriftDetector` with configurable window monitors fix acceptance rate. When `drift_score > 0.10` (10% accuracy drop over 50 vs. 200 corpus runs), triggers model retraining. See Section 11.5.3 for unified drift metric.
+
+**Fix pattern library**: 15 bootstrap `FixPattern` entries mapping error categories to regex-based replacements with success rate tracking (e.g., `MissingQuotes` → quote variable, 94% success rate).
+
+**Cross-references**: Oracle unification in Section 11.5; Aprender training pipeline in Section 11.7; PokaYoke quality gates in Section 11.7.2.
+
+#### 11.13.4 Rich ASCII Lint Reporting (Implemented)
+
+Rich reporting provides Tufte-principled (Tufte, 2001 [38]) visual output using box-drawing characters, sparklines, and histogram bars. This complements the ANSI color palette defined in Section 11.12.
+
+**Report structure** (`RichLintReport`): header, summary panel, cluster analysis (Pareto), fault localization (SBFL), fix suggestions, trend sparklines, footer with CITL export.
+
+**Visualization primitives**:
+- Box-drawing: `╔═╗║╠╣╚═╝╦╩╬` (double-line Unicode set)
+- Sparklines: `sparkline(data, width)` → `▂▃▄▅▆▇█` (normalized to data range)
+- Histogram bars: `histogram_bar(value, max, width)` → `████░░░░` (filled + empty blocks)
+
+**Implementation**: `rash/src/quality/lint_report.rs`, `rash/src/quality/report.rs`.
+
+**Cross-reference**: ANSI color constants and grade/percentage coloring in Section 11.12.
+
+#### 11.13.5 Control Flow Graph Analysis (Implemented)
+
+Shell-specific CFG generation enables complexity metrics beyond simple line counting.
+
+**API**: `build_cfg(ast: &ShellAst) -> ControlFlowGraph`
+
+**Node types**: `Entry`, `Exit`, `BasicBlock`, `Conditional`, `LoopHeader`, `FunctionEntry`, `SubshellEntry`.
+
+**Metrics computed**:
+
+| Metric | Formula | Threshold | Reference |
+|---|---|---|---|
+| Cyclomatic (McCabe) | E - N + 2P | ≤ 10 | McCabe, 1976 [39] |
+| Essential | # SCCs with >1 node | ≤ 4 | Watson & Wallace, 1996 [40] |
+| Cognitive | Weighted nesting depth | ≤ 15 | Shepperd, 1988 |
+| Halstead Volume | N × log₂(n) | Informational | Halstead, 1977 |
+| Max Depth | Longest path from entry | Informational | — |
+
+**CfgBuilder**: Shell-specific CFG construction with back-edge detection for loops, subshell boundaries, and trap handlers.
+
+**Implementation**: `rash/src/quality/cfg.rs` (`CfgBuilder`, 6+ tests).
+
+#### 11.13.6 ML Error Clustering (Implemented)
+
+Error clustering discovers patterns in lint output, reducing N individual diagnostics to K actionable clusters ranked by Pareto impact.
+
+**Algorithms** (`ClusteringAlgorithm` enum):
+- **k-means++** (Arthur & Vassilvitskii, 2007 [36]): Careful seeding for stable convergence
+- **DBSCAN** (Ester et al., 1996 [37]): Density-based, no k required, handles noise
+- **Hierarchical**: Agglomerative with configurable linkage
+
+**Distance metrics**: Euclidean, Cosine, Jaccard.
+
+**Cluster output** (`ErrorCluster`): centroid feature vector, member diagnostics, `RootCause` enum (`TranspilerGap`, `MissingRule`, `FalsePositive`, `Unknown`), fix confidence score, sample errors, blocked examples.
+
+**Integration**: Cluster results feed into rich report (Section 11.13.4) Pareto analysis panel and CITL export for organizational intelligence.
+
+#### 11.13.7 Quality Gates (ML-Specific)
+

+| 3 | Production scripts transpile | 50 real-world scripts | >= 95% pass |
+| 4 | No regressions over time | Full corpus run weekly | Monotonic or stable |
+| 4 | New entries do not break old ones | Add 10 entries, run full suite | Zero regressions |
+| 4 | 100% rate is temporary | Add 50 harder entries after convergence | Rate drops, then recovers |
+| 4 | Corpus grows forever | Measure corpus SIZE alongside rate | Monotonically increasing |

+```
+
+The convergence curve follows a **sawtooth pattern**, NOT a monotonic sigmoid. Each time 100% is reached, new harder entries are added, causing the rate to drop temporarily. The transpiler is then improved to recover. This is the healthy Kaizen cadence: perpetual challenge and improvement.
+
+The corpus SIZE line is monotonically increasing. The RATE line oscillates as new challenges are introduced and overcome. A flat rate line at 100% for more than 2 iterations indicates the corpus has stopped growing -- this is an anti-pattern (see Appendix C).
+
+## Appendix C: Anti-Patterns (What NOT to Do)
+
+| Anti-Pattern | Why It's Wrong | Correct Response |
+|---|---|---|
+| **Modify corpus entry to match transpiler bug** | Destroys the falsifier. Hides the defect. Scientific fraud. | Fix the transpiler. The corpus is ground truth. |
+| **Remove a failing corpus entry** | Evidence destruction. The entry revealed a real defect. | Fix the transpiler. Keep the entry forever. |
+| **Stop adding entries after 100%** | Static corpus = static quality. New bugs will go undetected. | Add 50 harder entries immediately. |
+| **Weaken expected output to be less specific** | Makes the test less effective at catching regressions. | Keep strict expectations. Fix the transpiler. |
+| **Skip corpus entries in CI** | Defeats the purpose of automated quality enforcement. | Fix whatever is slow/broken. Run all entries always. |
+| **Declare the transpiler "done"** | No transpiler is ever done. New Rust syntax, new edge cases. | Keep growing the corpus. Kaizen has no end. |
+| **Blame the corpus when rate drops** | The corpus is the oracle. The transpiler is the SUT. | Rate drops are healthy -- they mean the corpus found defects. |

-# Specification: ML-Powered Linting, Error Classification, and Rich Reporting
-
-**Document ID:** BASHRS-SPEC-ML-001
-**Version:** 1.0.0
-**Status:** IMPLEMENTED
-**Created:** 2025-12-07
-**Implemented:** 2025-12-07
-**Author:** Claude Code + Noah Gift
-
-## Executive Summary
-
-This specification defines enhancements to bashrs for ML-powered error classification, spectrum-based fault localization, and rich ASCII reporting. Following Toyota Production System (TPS) principles, we implement **Jidoka** (automation with human touch) for intelligent error handling and **Visual Management** for immediate feedback through rich terminal output.

-
-## 1. Motivation
-
-Current bashrs linting provides diagnostic output but lacks:
-
-1. **Intelligent Classification**: Errors are reported individually without clustering or pattern recognition
-2. **Root Cause Analysis**: No automated fault localization when multiple issues exist
-3. **Learning from Feedback**: No mechanism to improve fix suggestions based on user acceptance
-4. **Visual Feedback**: Plain text output without progress visualization or statistical summaries
-

-## 2. Toyota Way Alignment
-
-This specification follows the 14 principles of the Toyota Way [1]:
-
-| Principle | Application in bashrs |
-|-----------|----------------------|

-
-#### 3.1.2 CLI Integration
-
-```bash
-# Tier 1: Fast feedback (sub-second)
-bashrs gate --tier=1 # Genchi Genbutsu: The `bashrs gate` command must search for `.pmat-gates.toml` in parent directories.
-# Respect for People: Error messages for missing config should state where it looked and offer to create a default.
-# Built-in Quality: Unit tests are needed for the config loading mechanism to verify parsing of valid/invalid TOML.
-# Muda: The current implementation of TOML parsing errors in code loses specific line/column details; these need to be preserved to reduce debugging waste.
-# Standardized Work: Inconsistent field naming (`run_clippy` vs `check_coverage`) should be standardized (e.g., `enable_clippy`, `enable_coverage`).

-### 3.2 Tarantula SBFL Fault Localization
-
-**Source:** Adapted from organizational-intelligence-plugin
-**Reference:** Jones & Harrold (2005) [2], Abreu et al. (2009) [3]
-
-#### 3.2.1 Theoretical Foundation
-
-Spectrum-Based Fault Localization (SBFL) uses test execution traces to rank code locations by "suspiciousness." The intuition: code executed more by failing tests than passing tests is more likely to contain bugs.
-
-**Tarantula Formula:**
-```
-suspiciousness(s) = (failed(s)/totalFailed) / ((passed(s)/totalPassed) + (failed(s)/totalFailed))
-```
-
-**Ochiai Formula (often superior):**
-```
-suspiciousness(s) = failed(s) / sqrt(totalFailed × (failed(s) + passed(s)))
-```
-
-**DStar Formula (configurable exponent):**
-```
-suspiciousness(s) = failed(s)^* / (passed(s) + (totalFailed - failed(s)))
-```
-
-#### 3.2.2 Data Structures
-
-```rust
-/// Statement identifier for fault localization
-#[derive(Debug, Clone, Hash, Eq, PartialEq, Serialize, Deserialize)]
-pub struct StatementId {
-    pub file: PathBuf,
-    pub line: usize,
-    pub column: Option<usize>,
-    pub rule_code: Option<String>,  // e.g., "SEC010"
-}
-
-/// Coverage data per statement
-#[derive(Debug, Clone, Serialize, Deserialize)]
-pub struct StatementCoverage {
-    pub id: StatementId,
-    pub executed_by_passed: usize,
-    pub executed_by_failed: usize,
-}
-
-/// SBFL formula selection
-#[derive(Debug, Clone, Copy, Default)]
-pub enum SbflFormula {
-    #[default]
-    Tarantula,
-    Ochiai,
-    DStar { exponent: u32 },
-}
-
-/// Suspiciousness ranking result
-#[derive(Debug, Clone, Serialize, Deserialize)]
-pub struct SuspiciousnessRanking {
-    pub rank: usize,
-    pub statement: StatementId,
-    pub suspiciousness: f32,
-    pub formula_scores: HashMap<String, f32>,
-    pub explanation: String,
-}
-```
-
-#### 3.2.3 Integration with Linting
-
-```rust
-/// Locate most suspicious rules when multiple diagnostics exist
-pub fn localize_faults(
-    diagnostics: &[Diagnostic],
-    test_results: &TestResults,
-) -> Vec<SuspiciousnessRanking> {
-    // Group diagnostics by rule code
-    let rule_coverage = compute_rule_coverage(diagnostics, test_results);
-
-    // Apply SBFL formula
-    let rankings = apply_sbfl(rule_coverage, SbflFormula::Ochiai);
-
-    // Return top-N most suspicious
-    rankings.into_iter().take(10).collect()
-}

-### 3.4 Rich ASCII Reporting and Visualization
-
-**Source:** Adapted from depyler ConvergenceReporter and pmat dashboard
-**Reference:** Few (2006) [6], Tufte (2001) [7]
-
-#### 3.4.1 Design Principles
-
-Following Tufte's principles of analytical design [7]:
-
-1. **Show comparisons** - Cluster distributions, before/after
-2. **Show causality** - Root cause chains, SBFL rankings
-3. **Show multivariate data** - Multiple metrics per diagnostic
-4. **Integrate evidence** - Citations, confidence scores
-5. **Document everything** - Timestamps, tool versions
-6. **Content matters most** - Data density over decoration
-
-#### 3.4.2 Report Components
-
-```rust
-/// Rich report with ASCII visualization
-pub struct RichLintReport {
-    pub header: ReportHeader,
-    pub summary: SummaryPanel,
-    pub cluster_analysis: ClusterPanel,
-    pub fault_localization: SbflPanel,
-    pub fix_suggestions: FixPanel,
-    pub trend_sparklines: TrendPanel,
-    pub footer: ReportFooter,
-}
-
-/// ASCII box drawing characters
-pub mod box_chars {
-    pub const TOP_LEFT: char = '╔';
-    pub const TOP_RIGHT: char = '╗';
-    pub const BOTTOM_LEFT: char = '╚';
-    pub const BOTTOM_RIGHT: char = '╝';
-    pub const HORIZONTAL: char = '═';
-    pub const VERTICAL: char = '║';
-    pub const T_DOWN: char = '╦';
-    pub const T_UP: char = '╩';
-    pub const T_RIGHT: char = '╠';
-    pub const T_LEFT: char = '╣';
-    pub const CROSS: char = '╬';
-}
-```
-
-#### 3.4.3 Sparkline Generation
-
-```rust
-/// Generate ASCII sparkline for trend data
-pub fn sparkline(data: &[f64], width: usize) -> String {
-    const CHARS: &[char] = &[' ', '▂', '▃', '▄', '▅', '▆', '▇', '█'];
-
-    let min = data.iter().cloned().fold(f64::INFINITY, f64::min);
-    let max = data.iter().cloned().fold(f64::NEG_INFINITY, f64::max);
-    let range = max - min;
-
-    data.iter()
-        .map(|&v| {
-            let normalized = if range > 0.0 { (v - min) / range } else { 0.5 };
-            let index = ((normalized * 7.0).round() as usize).min(7);
-            CHARS[index]
-        })
-        .collect()
-}
-
-/// Generate ASCII histogram bar
-pub fn histogram_bar(value: f64, max_value: f64, width: usize) -> String {
-    let filled = ((value / max_value) * width as f64).round() as usize;
-    let empty = width - filled;

+# bashrs installer - TDD-First Installer Framework Specification
+
+**Date**: 2025-12-26
+**Version**: 2.0.0
+**Paradigm**: Pure Rust Installer Generation with TDD by Default
+**Integration**: trueno-viz for visualization, bashrs for transpilation, renacer for golden traces
+
+## Executive Summary
+
+The `bashrs installer` command solves the pervasive problem of unreliable, untestable bash installers. Instead of writing fragile shell scripts that fail mysteriously, developers generate **pure Rust installers** that are:
+
+1. **TDD by default** - Tests exist before implementation [1].
+2. **Checkpointed** - Resume from any failure point.
+3. **Observable** - Visual progress, structured logging, tracing [5].
+4. **Deterministic** - Same inputs always produce same outputs [3].
+5. **Falsifiable** - Every claim can be empirically tested [2].
+6. **Cryptographically Verified** - Ed25519 signatures on all artifacts *(NEW v2.0)*.
+7. **Hermetically Reproducible** - Bit-for-bit identical builds across machines *(NEW v2.0)*.
+8. **Container-Native** - First-class multi-distro testing in isolation *(NEW v2.0)*.
+
+**Philosophy**: Apply Toyota Production System (TPS) principles [4] and Karl Popper's falsificationism [2] to installer engineering.
+
+---

+
+## Open Tickets Addressed by This Specification
+
+This specification consolidates and addresses the following bashrs tickets. The installer command will help resolve parser/linter issues by providing a structured, testable alternative to raw bash scripts.
+
+### Currently Open Issues (11 tickets)
+
+| Issue | Priority | Title | How Installer Helps |
+|-------|----------|-------|---------------------|
+| **#103** | P0 | Parser fails on common bash array syntax | Installer uses declarative TOML—no array parsing needed |
+| **#102** | P1 | SC2128/SC2199: False positive on local scalar variables | Installer generates verified shell, bypassing linter edge cases |
+| **#101** | P1 | SC2024 false positive: `sudo sh -c 'cmd > file'` flagged | Installer uses typed `Action::Script` with privilege escalation |
+| **#100** | P1 | SC2024 false positive: `| sudo tee` pattern | Built-in `file_write` action with privilege handling |
+| **#99** | P1 | SC2154 false positive: Variables in case statements | Installer tracks variable scope via AST, not heuristics |
+| **#98** | P1 | SC2154 false positive: EUID bash builtin not recognized | Installer has built-in `privileges = "root"` check |
+| **#97** | P2 | SEC010 false positive: Custom path validation not recognized | Installer uses typed `Precondition::PathValidated` |
+| **#96** | P2 | False positives in heredocs with quoted delimiters | Installer uses structured templates, not raw heredocs |
+| **#95** | P2 | SC2154/SC2140 for sourced variables and heredoc expansion | Installer explicit `[step.environment]` declarations |
+| **#94** | P1 | exec() generates shell exec; pipe detection too aggressive | Installer has typed `Action::Exec` vs `Action::Pipeline` |
+| **#93** | P1 | Parser fails on inline if/then/else/fi syntax | Installer uses Rust control flow, transpiles to safe shell |
+
+### Previously Resolved (Context)
+
+| Issue | Status | Resolution |
+|-------|--------|------------|
+| #2 | ✅ RESOLVED | Makefile multi-line format preservation with `--preserve-formatting` |
+| #4 | ✅ RESOLVED | Complete bash parser - all 9 phases including heredocs, pipelines |
+| #21 | ✅ RESOLVED | SC2171 false positive with JSON brackets in heredocs |
+| #22 | ✅ RESOLVED | SC2247 false positive with math operations in awk/bc |
+
+### How the Installer Framework Solves These Issues
+
+The core insight is that **many linter false positives stem from trying to understand unstructured bash**. The installer framework sidesteps this by:
+
+1. **Declarative over Imperative**: Instead of parsing `if [ "$EUID" -ne 0 ]; then`, use:
+   ```toml
+   [installer.requirements]
+   privileges = "root"  # Typed, no parsing ambiguity
+   ```
+
+2. **Typed Actions over Raw Scripts**: Instead of linting `sudo tee`, use:
+   ```toml
+   [[step]]
+   action = "file-write"
+   path = "/etc/apt/sources.list.d/docker.list"
+   content = "deb [arch=amd64] https://..."
+   privileges = "elevated"  # Handles sudo internally
+   ```
+
+3. **Explicit Variable Scope**: Instead of tracking sourced variables:
+   ```toml
+   [step.environment]
+   DOCKER_VERSION = { from_env = "DOCKER_VERSION", default = "latest" }
+   ```
+
+4. **Generated Shell is Correct by Construction**: The transpiler output passes ShellCheck because it's generated from verified templates, not parsed from arbitrary input.
+

+### Acceptance Criteria for Key Tickets
+
+#### #104: Core `bashrs installer` subcommand
+```bash
+# MUST support these commands
+bashrs installer init <name>           # Create new installer project
+bashrs installer run <path>            # Execute installer
+bashrs installer validate <path>       # Validate without executing
+bashrs installer test <path>           # Run installer test suite
+
+# MUST parse installer.toml format
+# MUST generate Rust code from declarative spec
+# MUST pass all existing bashrs quality gates (88%+ coverage, 92%+ mutation score)
+```
+
+#### #115: `bashrs installer from-bash` (Key for resolving parser issues)
+```bash
+# Convert problematic bash script to safe installer format
+bashrs installer from-bash install.sh --output my-installer/
+
+# MUST handle:
+# - Array syntax (#103) → converted to TOML lists
+# - Case statements (#99) → converted to step conditions
+# - Heredocs (#96) → converted to template files
+# - sudo patterns (#100, #101) → converted to privileged actions
+# - inline if/then (#93) → converted to step preconditions
+
+# Example transformation:
+# FROM:
+#   if [ "$EUID" -ne 0 ]; then echo "Run as root"; exit 1; fi
+# TO:
+#   [installer.requirements]
+#   privileges = "root"
+```
+
+#### #108: Artifact signature verification
+```rust
+// MUST implement Ed25519 verification
+// MUST support TOFU and explicit keyring modes
+// MUST fail closed (reject unsigned artifacts by default)
+
+#[test]
+fn falsify_signature_bypass() {
+    let tampered_artifact = tamper_with_artifact(&artifact);
+    let result = verify_artifact(&tampered_artifact, &keyring);
+    assert!(result.is_err(), "FALSIFIED: Tampered artifact passed verification");
+}
+```
+
+#### #109: Hermetic build mode
+```bash
+# MUST generate installer.lock with pinned versions
+# MUST use SOURCE_DATE_EPOCH for deterministic timestamps
+# MUST fail if artifact hash drifts from lockfile
+
+# Falsification test:
+bashrs installer run --hermetic # on machine A
+bashrs installer run --hermetic # on machine B
+# Output hashes MUST match
+```
+
+#### #113: Golden trace regression
+```bash
+# MUST integrate with renacer
+# MUST capture syscall patterns
+# MUST detect new/removed/changed syscalls
+
+bashrs installer golden-capture --trace baseline
+bashrs installer golden-compare --trace baseline
+# Exit code 0 = match, 1 = regression
+```
+
+### Resolution Strategy for Existing Parser Issues
+
+| Issue | Direct Fix | Installer Workaround |
+|-------|------------|---------------------|
+| #103 (arrays) | Extend parser for `arr=()` syntax | Use TOML `packages = ["a", "b"]` |
+| #102 (SC2128) | Add local variable tracking | Explicit `[step.variables]` declarations |
+| #101/#100 (sudo) | Context-aware sudo pattern detection | Built-in `privileges = "elevated"` action |
+| #99 (case vars) | Control flow variable analysis | Step conditions with typed variables |
+| #98 (EUID) | Add bash builtins to known variables | `[installer.requirements] privileges = "root"` |
+| #97 (SEC010) | Custom function recognition | Typed `Precondition` validators |
+| #96/#95 (heredoc) | Improve heredoc context tracking | Template files with explicit expansion |
+| #94 (exec/pipe) | Separate exec vs pipeline codegen | Typed `Action::Exec` vs `Action::Pipeline` |
+| #93 (inline if) | Parser grammar extension | Rust control flow → generated shell |
+
+**Recommendation**: For P0/P1 issues (#93, #94, #98, #99, #100, #101, #102, #103), implementing `bashrs installer from-bash` (#115) provides an immediate workaround by converting problematic scripts to the safer declarative format. Direct parser fixes can follow as time permits.
+
+---
+
+## The Problem: Why Bash Installers Fail
+
+### Current State (Broken)
+
+Traditional shell scripts lack the structural guarantees required for reliable systems engineering. They often suffer from "Configuration Drift," where the actual state of the system diverges from the expected state over time, a phenomenon that makes deterministic restoration impossible [3].
+
+```bash
+#!/bin/bash
+# install.sh - The typical disaster
+
+apt-get update          # Fails silently on network issues
+apt-get install -y foo  # Version drift, conflicts
+curl ... | bash         # No verification, MITM attacks
+mkdir -p /opt/app       # No idempotency check
+cp -r . /opt/app        # No rollback on failure
+systemctl enable foo    # No status verification
+echo "Done!"            # Lies - no actual verification
+```
+
+**Failure Modes**:
+- **Lack of Atomicity**: Scripts fail mid-way, leaving the system in an inconsistent, broken state.
+- **Observability Deficit**: Silent failures are buried in unstructured text output [5].
+- **Testing Gap**: Impossible to unit test individual steps in isolation.
+- **Rollback Absence**: No mechanism to revert changes upon failure.
+- **Supply Chain Blindness**: No verification of downloaded artifacts' provenance.
+
+### Toyota Way Analysis (7 Wastes in Installers)
+
+Applying Liker's analysis of waste (*muda*) in the Toyota Production System [4] to software installation:
+
+| Waste Type | Installer Manifestation |
+|------------|------------------------|
+| **Defects** | Script fails mid-way, leaves system in broken state (Quality Debt). |
+| **Overproduction** | Re-downloading already-installed packages (Inefficiency). |
+| **Waiting** | No parallelization of independent steps (Resource Underutilization). |
+| **Non-utilized talent** | Developers debugging broken scripts instead of building features. |
+| **Transportation** | Unnecessary file copies, temp directories, and data movement. |
+| **Inventory** | Orphaned packages, leftover artifacts, and temp files. |
+| **Motion** | Manual intervention, SSH-ing to servers to "fix" failed installs. |
+| **Extra-processing** | Redundant checks, manual verifications, and unnecessary operations. |

+
+### Solution: Ed25519 Artifact Signing
+
+```toml

+# Require signatures for all external artifacts
+require_signatures = true
+
+# Transparency log for audit trail (Sigstore-compatible)
+transparency_log = "https://rekor.sigstore.dev"
+
+[[artifact]]
+id = "docker-gpg-key"
+url = "https://download.docker.com/linux/ubuntu/gpg"
+# Ed25519 signature of the artifact
+signature = "signatures/docker-gpg-key.sig"
+# Expected content hash (SHA-256)
+sha256 = "1500c1f56fa9e26b9b8f42452a553675796ade0807cdce11975eb98170b3a570"
+# Public key ID for verification
+signed_by = "docker-release-2024"
+
+[[artifact]]
+id = "myapp-binary"
+url = "https://releases.myapp.io/v${VERSION}/myapp-${ARCH}"
+signature = "https://releases.myapp.io/v${VERSION}/myapp-${ARCH}.sig"
+sha256_url = "https://releases.myapp.io/v${VERSION}/SHA256SUMS"

+## Enhancement §5: Distributed Execution
+
+### Problem
+
+Large installers with many independent steps waste time executing sequentially. Additionally, build artifacts could be cached across machines.
+
+### Solution: Build Graph Parallelization + sccache Integration
+
+```toml
+[installer.distributed]
+# Enable distributed execution
+enabled = true
+
+# sccache server for build artifact caching
+sccache_server = "10.0.0.50:4226"
+
+# Remote execution endpoints (optional)
+remote_executors = [
+    { host = "builder-1.internal", capabilities = ["apt", "docker"] },
+    { host = "builder-2.internal", capabilities = ["apt", "docker", "gpu"] },
+]
+
+# Maximum parallel steps (respecting dependency graph)
+max_parallel_steps = 8
+
+# Build graph optimization
+[installer.distributed.optimization]
+# Merge consecutive apt-install steps
+coalesce_package_installs = true
+# Prefetch artifacts during earlier steps
+speculative_download = true
+```

+## Enhancement §6: Golden Trace Regression Detection
+
+### Integration with renacer
+
+The bashrs repository already integrates with [renacer](https://github.com/paiml/renacer) for syscall tracing. Extend this to installers.
+
+```toml
+[installer.golden_traces]
+enabled = true
+trace_dir = ".golden-traces"
+
+# Capture these syscall categories
+capture = ["file", "network", "process", "permission"]
+
+# Ignore these paths (noise reduction)
+ignore_paths = [
+    "/proc/*",
+    "/sys/*", 
+    "/dev/null",
+    "/tmp/bashrs-*",
+]
+```
+
+### Rust Implementation
+
+```rust
+use renacer::{Tracer, SyscallEvent, TraceComparison};

+
+[Calling installer_scaffold with description="PostgreSQL 16 with replication support" target_os=["ubuntu:22.04", "ubuntu:24.04"]]

+
+## Toyota Way Principles Applied
+
+### 1. Jidoka (Automation with Human Touch)
+
+**Principle**: Stop and fix problems immediately; don't propagate defects [4].
+
+```toml
+[[step]]
+id = "install-package"
+
+[step.on_failure]
+action = "stop"  # Jidoka: Stop the line
+notify = ["ops@company.com"]
+preserve_state = true  # For debugging
+
+# Human intervention required before proceeding
+[step.recovery]
+require_approval = true
+approval_timeout = "1h"
+```
+
+### 2. Kaizen (Continuous Improvement)
+
+**Principle**: Collect metrics; improve based on data [4].
+
+```rust
+pub struct InstallerMetrics {
+    /// Track timing trends across runs
+    pub step_durations: HashMap<StepId, Vec<Duration>>,
+
+    /// Track failure patterns
+    pub failure_counts: HashMap<StepId, u32>,
+
+    /// Track retry effectiveness
+    pub retry_success_rate: HashMap<StepId, f64>,
+    
+    /// NEW v2.0: Track signature verification latency
+    pub signature_verify_times: HashMap<ArtifactId, Vec<Duration>>,
+    
+    /// NEW v2.0: Track hermetic build reproducibility
+    pub hermetic_hash_stability: HashMap<StepId, HashSet<String>>,
+}
+```
+
+### 3. Heijunka (Level Loading)
+
+**Principle**: Parallelize independent operations; avoid resource contention [4].
+
+```toml
+[[step]]
+id = "download-artifacts"
+parallel_group = "downloads"  # Run in parallel with other downloads
+
+[[step]]
+id = "download-keys"
+parallel_group = "downloads"  # Same group = parallel execution
+
+# NEW v2.0: Resource constraints prevent unsafe parallelism
+[[step]]
+id = "apt-install"
+[step.constraints]
+exclusive_resource = "apt-lock"  # Only one apt step at a time
+```
+
+### 4. Genchi Genbutsu (Go and See)
+
+**Principle**: Real-time visibility into actual system state [4].
+
+```bash
+# Real-time monitoring
+bashrs installer run ./my-installer --live-dashboard
+
+# NEW v2.0: Real-time trace comparison
+bashrs installer run ./my-installer --compare-golden install-v1 --live
+```
+
+### 5. Poka-Yoke (Error Prevention)
+
+**Principle**: Design out the possibility of errors [4].
+
+```rust
+/// Poka-Yoke: Type-safe step definitions prevent common errors
+pub struct Step<S: StepState> {
+    id: StepId,  // Compile-time unique ID enforcement
+    preconditions: Vec<Precondition>,
+    action: Action,
+    postconditions: Vec<Postcondition>,
+    /// NEW v2.0: Required artifact references (type-checked)
+    artifacts: Vec<ArtifactRef>,
+    _state: PhantomData<S>,
+}
+
+/// NEW v2.0: Artifact references are validated at parse time
+pub struct ArtifactRef {
+    id: ArtifactId,
+    /// Proof that this artifact exists in the installer spec
+    _exists: PhantomData<ArtifactExists>,
+}
+```
+

+
+## Karl Popper Falsification Checklist
+
+### Principle: A Claim is Only Scientific if it Can Be Proven False
+
+According to Popper [2], a theory (or installer step) is only scientific if it makes specific predictions that can be tested and potentially falsified.
+
+### Falsification Test Matrix (Extended for v2.0)
+
+| Claim | Test Method | How to Disprove |
+|-------|-------------|-----------------|
+| "Step is idempotent" | Run step twice, compare system state | Different state after 2nd run = FALSIFIED [3] |
+| "Step has no side effects on failure" | Kill step mid-execution, check state | Partial state changes = FALSIFIED |
+| "Rollback restores original state" | Run step, rollback, compare to pre-state | Any difference = FALSIFIED |
+| "Timeout is honored" | Set timeout=1s, run 10s operation | Runs longer than timeout = FALSIFIED |
+| "Retry logic works" | Inject transient failure, verify retry | No retry or wrong behavior = FALSIFIED |
+| **"Artifact signature is valid"** | Tamper with artifact, attempt verify | Verification succeeds = FALSIFIED |
+| **"Build is hermetic"** | Run on different machine, compare hash | Different output hash = FALSIFIED |
+| **"Golden trace matches"** | Run installer, compare syscalls | New/missing syscalls = FALSIFIED |
+| **"Dry-run is accurate"** | Compare dry-run diff to actual changes | Mismatch = FALSIFIED |
+

+
+## Migration Guide: v1.x → v2.0
+
+### Breaking Changes
+
+1. **`installer.toml` format**: New required sections for `[installer.security]`
+2. **Artifact definitions**: Must include `sha256` and optionally `signature`
+3. **CLI flags**: `--verify-signatures` is now default (use `--no-verify` to skip)
+
+### Migration Steps
+
+```bash
+# 1. Generate lockfile for existing installer
+bashrs installer lock ./my-installer
+
+# 2. Add artifact signatures (or use TOFU mode initially)
+bashrs installer run ./my-installer --trust-on-first-use
+
+# 3. Capture golden trace baseline
+bashrs installer golden-capture ./my-installer --trace v2-baseline
+
+# 4. Update CI to use hermetic mode
+bashrs installer run ./my-installer --hermetic --verify-signatures
+```

+# bashrs installer - TDD-First Installer Framework Specification
+
+**Date**: 2025-12-26
+**Version**: 1.1.0
+**Paradigm**: Pure Rust Installer Generation with TDD by Default
+**Integration**: trueno-viz for visualization, bashrs for transpilation
+
+## Executive Summary
+
+The `bashrs installer` command solves the pervasive problem of unreliable, untestable bash installers. Instead of writing fragile shell scripts that fail mysteriously, developers generate **pure Rust installers** that are:
+
+1. **TDD by default** - Tests exist before implementation [1].
+2. **Checkpointed** - Resume from any failure point.
+3. **Observable** - Visual progress, structured logging, tracing [5].
+4. **Deterministic** - Same inputs always produce same outputs [3].
+5. **Falsifiable** - Every claim can be empirically tested [2].
+
+**Philosophy**: Apply Toyota Production System (TPS) principles [4] and Karl Popper's falsificationism [2] to installer engineering.
+
+---
+
+## The Problem: Why Bash Installers Fail
+
+### Current State (Broken)
+
+Traditional shell scripts lack the structural guarantees required for reliable systems engineering. They often suffer from "Configuration Drift," where the actual state of the system diverges from the expected state over time, a phenomenon that makes deterministic restoration impossible [3].
+
+```bash
+#!/bin/bash
+# install.sh - The typical disaster
+
+apt-get update          # Fails silently on network issues
+apt-get install -y foo  # Version drift, conflicts
+curl ... | bash         # No verification, MITM attacks
+mkdir -p /opt/app       # No idempotency check
+cp -r . /opt/app        # No rollback on failure
+systemctl enable foo    # No status verification
+echo "Done!"            # Lies - no actual verification
+```
+
+**Failure Modes**:
+- **Lack of Atomicity**: Scripts fail mid-way, leaving the system in an inconsistent, broken state.
+- **Observability Deficit**: Silent failures are buried in unstructured text output [5].
+- **Testing Gap**: Impossible to unit test individual steps in isolation.
+- **Rollback Absence**: No mechanism to revert changes upon failure.
+
+### Toyota Way Analysis (7 Wastes in Installers)
+
+Applying Liker's analysis of waste (*muda*) in the Toyota Production System [4] to software installation:
+
+| Waste Type | Installer Manifestation |
+|------------|------------------------|
+| **Defects** | Script fails mid-way, leaves system in broken state (Quality Debt). |
+| **Overproduction** | Re-downloading already-installed packages (Inefficiency). |
+| **Waiting** | No parallelization of independent steps (Resource Underutilization). |
+| **Non-utilized talent** | Developers debugging broken scripts instead of building features. |
+| **Transportation** | Unnecessary file copies, temp directories, and data movement. |
+| **Inventory** | Orphaned packages, leftover artifacts, and temp files. |
+| **Motion** | Manual intervention, SSH-ing to servers to "fix" failed installs. |
+| **Extra-processing** | Redundant checks, manual verifications, and unnecessary operations. |
+

+
+## Solution: `bashrs installer` Command
+
+### Command Overview
+
+```bash
+# Generate a new installer project
+bashrs installer init my-app-installer
+
+# Scaffold from existing bash script
+bashrs installer from-bash install.sh --output my-installer/
+
+# Run installer with full observability
+bashrs installer run ./my-installer \
+  --checkpoint-dir /var/lib/installer/checkpoints \
+  --log-level debug \
+  --trace \
+  --progress
+
+# Resume from checkpoint
+bashrs installer resume ./my-installer --from step-5
+
+# Validate installer without executing
+bashrs installer validate ./my-installer
+
+# Generate test suite
+bashrs installer test ./my-installer --coverage
+```

+
+## Toyota Way Principles Applied
+
+### 1. Jidoka (Automation with Human Touch)
+
+**Principle**: Stop and fix problems immediately; don't propagate defects [4].
+
+```toml
+[[step]]
+id = "install-package"
+
+[step.on_failure]
+action = "stop"  # Jidoka: Stop the line
+notify = ["ops@company.com"]
+preserve_state = true  # For debugging
+
+# Human intervention required before proceeding
+[step.recovery]
+require_approval = true
+approval_timeout = "1h"
+```
+
+### 2. Kaizen (Continuous Improvement)
+
+**Principle**: Collect metrics; improve based on data [4].
+
+```rust
+pub struct InstallerMetrics {
+    /// Track timing trends across runs
+    pub step_durations: HashMap<StepId, Vec<Duration>>,
+
+    /// Track failure patterns
+    pub failure_counts: HashMap<StepId, u32>,
+
+    /// Track retry effectiveness
+    pub retry_success_rate: HashMap<StepId, f64>,
+}
+```
+
+### 3. Heijunka (Level Loading)
+
+**Principle**: Parallelize independent operations; avoid resource contention [4].
+
+```toml
+[[step]]
+id = "download-artifacts"
+parallel_group = "downloads"  # Run in parallel with other downloads
+
+[[step]]
+id = "download-keys"
+parallel_group = "downloads"  # Same group = parallel execution
+```
+
+### 4. Genchi Genbutsu (Go and See)
+
+**Principle**: Real-time visibility into actual system state [4].
+
+```bash
+# Real-time monitoring
+bashrs installer run ./my-installer --live-dashboard
+```
+
+### 5. Poka-Yoke (Error Prevention)
+
+**Principle**: Design out the possibility of errors [4].
+
+```rust
+/// Poka-Yoke: Type-safe step definitions prevent common errors
+pub struct Step<S: StepState> {
+    id: StepId,  // Compile-time unique ID enforcement
+    preconditions: Vec<Precondition>,  // Must be satisfied before execution
+    action: Action,
+    postconditions: Vec<Postcondition>,  // Must be true after execution
+    _state: PhantomData<S>,
+}
+```
+
+---
+
+## Karl Popper Falsification Checklist
+
+### Principle: A Claim is Only Scientific if it Can Be Proven False
+
+According to Popper [2], a theory (or installer step) is only scientific if it makes specific predictions that can be tested and potentially falsified.
+
+### Falsification Test Matrix
+
+| Claim | Test Method | How to Disprove |
+|-------|-------------------|-----------------|
+| "Step is idempotent" | Run step twice, compare system state | Different state after 2nd run = FALSIFIED [3] |
+| "Step has no side effects on failure" | Kill step mid-execution, check state | Partial state changes = FALSIFIED |
+| "Rollback restores original state" | Run step, rollback, compare to pre-state | Any difference = FALSIFIED |
+| "Timeout is honored" | Set timeout=1s, run 10s operation | Runs longer than timeout = FALSIFIED |
+| "Retry logic works" | Inject transient failure, verify retry | No retry or wrong behavior = FALSIFIED |
+
+### Falsification Tests in Code
+
+```rust
+#[cfg(test)]
+mod falsification_tests {
+    use super::*;
+    use proptest::prelude::*;
+
+    /// FALSIFIABLE: "Every step is idempotent"
+    /// DISPROOF: Run step twice, system state differs
+    #[test]
+    fn falsify_step_idempotency() {
+        let step = load_step("install-docker");
+        let ctx = TestContext::new();
+
+        // First execution
+        let state_after_first = execute_and_capture_state(&ctx, &step);
+
+        // Second execution (should be no-op)
+        let state_after_second = execute_and_capture_state(&ctx, &step);
+
+        // Falsification: If states differ, idempotency claim is FALSE
+        assert_eq!(
+            state_after_first, state_after_second,
+            "FALSIFIED: Step '{}' is not idempotent. State changed on re-execution.",
+            step.id
+        );
+    }
+
+    /// FALSIFIABLE: "Rollback restores original state"
+    /// DISPROOF: State after rollback differs from state before step
+    #[test]
+    fn falsify_rollback_completeness() {
+        let step = load_step("install-docker");
+        let ctx = TestContext::new();
+
+        // Capture state before
+        let state_before = capture_system_state(&ctx);
+
+        // Execute step
+        execute_step(&ctx, &step).unwrap();
+
+        // Rollback
+        rollback_step(&ctx, &step).unwrap();
+
+        // Capture state after rollback
+        let state_after_rollback = capture_system_state(&ctx);
+
+        // Falsification: If states differ, rollback claim is FALSE
+        let diff = state_before.diff(&state_after_rollback);
+        assert!(
+            diff.is_empty(),
+            "FALSIFIED: Rollback incomplete. Residual changes: {:?}",
+            diff

+# SPEC-SSC-2026-001: Shell Safety Classifier — Published on HuggingFace
+
+**Version**: 2.2.0
+**Status**: v2 COMPLETE (15 tickets done), v2.2 IN PROGRESS (SSC-023..027 production training pipeline)
+**Author**: paiml engineering
+**Date**: 2026-02-24
+**Requires**: bashrs >= 6.64.0, aprender >= 0.26.3, entrenar >= 1.0, trueno >= 0.15.0
+**HuggingFace Repo**: `paiml/shell-safety-classifier`
+
+---
+
+## Abstract
+
+This specification defines `paiml/shell-safety-classifier`, a transformer-based
+classifier that categorizes bash script snippets by safety risk level. The model
+is trained on bashrs's 17,942-entry corpus using aprender's neural encoder and
+training loop, then published to HuggingFace Hub.
+
+The project serves two purposes:
+1. **aprender** gets a real fine-tuning showcase with production training data
+2. **bashrs** gets an ML-powered safety classifier complementing its rule-based linter
+
+---
+
+## 1. Motivation
+
+### 1.1 The Gap
+
+bashrs has 14+ linter rules (SEC001-008, DET001-006, IDEM001+) that detect shell
+script safety issues through static analysis. These rules are precise but require
+per-pattern implementation. An ML classifier can learn safety patterns from the
+corpus holistically, catching issues that individual rules miss.
+
+aprender (pure Rust ML framework) needs real-world model showcases beyond toy
+examples. The bashrs corpus provides 17,942 labeled entries — real, structured
+training data with transpilation results (pass/fail, lint clean, deterministic,
+tier labels).
+
+### 1.2 Why This Model
+
+The bashrs corpus is uniquely suited for ML training:
+
+| Property | Value |
+|----------|-------|
+| Total entries | 17,942 |
+| Bash entries | ~16,431 |
+| Makefile entries | ~804 |
+| Dockerfile entries | ~707 |
+| Labels per entry | transpiled, lint_clean, deterministic, output_correct, tier |
+| Scoring dimensions | A/B1/B2/B3/C/D/E/F/G (9 dimensions, 100-point scale) |
+| Current corpus score | 99.1/100 A+ |
+

+
+## 2. Safety Classes
+
+The model classifies shell scripts into 5 safety categories derived from bashrs
+linter rules and corpus quality dimensions:
+
+| Class | Label | Index | Derivation | Example |
+|-------|-------|-------|------------|---------|
+| Safe | `safe` | 0 | lint_clean AND deterministic AND output_correct | `#!/bin/sh\necho "hello"` |
+| Needs Quoting | `needs-quoting` | 1 | Unquoted variable references detected | `echo $HOME` |
+| Non-Deterministic | `non-deterministic` | 2 | Contains `$RANDOM`, `$$`, `date`, timestamps | `echo $RANDOM` |
+| Non-Idempotent | `non-idempotent` | 3 | Missing `-p`/`-f` flags for safe re-run | `mkdir /tmp/build` |
+| Unsafe | `unsafe` | 4 | SEC001-008 violations (eval, curl\|bash, etc.) | `eval "$user_input"` |
+
+### 2.1 Label Derivation from Corpus
+
+Labels are derived from bashrs corpus JSONL export fields:
+
+```
+Priority: unsafe > non-deterministic > non-idempotent > needs-quoting > safe
+
+if !transpiled OR !lint_clean → unsafe (4)
+if !deterministic → non-deterministic (2)
+if has mkdir without -p OR rm without -f → non-idempotent (3)
+if has unquoted $VAR outside quotes → needs-quoting (1)
+if output_correct → safe (0)
+else → needs-quoting (1)
+```

+### 3.1 ShellVocabulary
+
+250 tokens organized by category:
+
+| Category | Count | Examples |
+|----------|-------|---------|
+| Special tokens | 5 | `[PAD]`, `[UNK]`, `[CLS]`, `[SEP]`, `[EOS]` |
+| Shebangs | 3 | `#!/bin/bash`, `#!/bin/sh`, `#!/usr/bin/env` |
+| Shell builtins | 37 | `echo`, `printf`, `read`, `cd`, `export`, `eval`, `exec` |
+| External commands | 34 | `mkdir`, `rm`, `cp`, `grep`, `sed`, `curl`, `wget` |
+| Control flow | 14 | `if`, `then`, `else`, `fi`, `for`, `while`, `case` |
+| Operators | 51 | `\|`, `&&`, `\|\|`, `>>`, `2>&1`, `$()`, `==`, `-eq` |
+| Variables | 23 | `$HOME`, `$RANDOM`, `$$`, `$?`, `$@`, `$PATH` |
+| Flags | 28 | `-p`, `-f`, `-rf`, `--force`, `--recursive`, `--parents` |
+| Strings/quoting | 5 | `"`, `'`, `\\`, `\n`, `\t` |
+| Numeric literals | 11 | `0`, `1`, `255`, `644`, `755` |
+| Common words | 39 | `file`, `dir`, `path`, `config`, `install`, `build` |
+
+### 3.2 Tokenization
+
+Shell-aware tokenization that preserves:
+- Shebangs as single tokens (`#!/bin/bash`)
+- Variable references (`$HOME`, `${VAR}`, `$(cmd)`)
+- Multi-character operators (`&&`, `||`, `>>`, `2>&1`)
+- Comment stripping (`# ...` removed)
+- Quoted string contents split into sub-tokens
+
+### 3.3 Model Configuration
+
+| Parameter | Value |
+|-----------|-------|
+| `vocab_size` | 251 (250 tokens + 1 safety margin) |
+| `embed_dim` | 64 |
+| `hidden_dim` | 128 |
+| `num_classes` | 5 |
+| `max_seq_len` | 64 |
+| `optimizer` | Adam (lr=0.01) |
+| `loss` | CrossEntropyLoss |
+| `epochs` | 50 |
+| `train/val split` | 80/20 |

+
+## 7. Usage
+
+### 7.1 Export Corpus (bashrs)
+
+```bash
+cd /path/to/bashrs
+cargo run -- corpus export-dataset --format jsonl > /tmp/corpus.jsonl
+# Outputs 17,942 JSONL lines with id, input_rust, expected_output,
+# lint_clean, deterministic, tier, format, score, grade
+```
+
+### 7.2 Train Model (aprender)
+
+```bash
+cd /path/to/aprender
+
+# With bashrs corpus (full training)
+cargo run --example shell_safety_training -- /tmp/corpus.jsonl
+
+# Without corpus (40 demo samples)
+cargo run --example shell_safety_training
+```
+
+**Output**:
+```
+/tmp/shell-safety-model/
+  model.safetensors  (weights)
+  vocab.json         (tokenizer)
+  config.json        (architecture)
+```
+
+### 7.3 Run Inference (aprender)
+
+```bash
+cargo run --example shell_safety_inference -- /tmp/shell-safety-model/
+```
+
+### 7.4 Publish to HuggingFace (aprender)

+## 10. v2: Qwen2.5-Coder Fine-Tuning with LoRA
+
+### 10.1 Motivation
+
+v1 trains an MLP from scratch with a 250-token vocabulary — it learns shell
+semantics from zero. Qwen2.5-Coder-0.5B already understands code/shell syntax
+from pretraining on billions of tokens. Fine-tuning with LoRA adapters leverages
+this pretrained knowledge while training only ~0.1% of parameters.
+
+### 10.2 Architecture (v2)

+### 10.7 Model Progression
+
+```
+v1 (DONE):  ShellVocab(250) -> MLP(64->128->64->5)        ~10K params, trains in seconds
+v2 (DONE):  Qwen2BPE(151K)  -> Qwen2.5-0.5B+LoRA -> Linear(896->5)  ~1.1M trainable, minutes
+v3 (FUTURE): Qwen3.5 + QLoRA(4-bit) -> Linear(dim->5)     ~1M trainable, production quality
+```
+
+### 10.8 Design-by-Contract Compliance
+
+| Principle | How Applied |
+|-----------|-------------|
+| **Poka-Yoke** | `ValidatedClassLogits` private constructor prevents invalid logit shapes |
+| **Jidoka** | Contract validation halts on first defect (wrong num_classes, NaN logits) |
+| **Falsification** | FALSIFY-CLASS-001..004 prove contracts reject bad inputs |
+| **PMAT shape validation** | ClassificationHead validates `hidden_size * num_classes` (mirrors PMAT-329/331) |
+| **Property testing** | proptest on label bounds, logit shapes, softmax sum invariant |
+| **ONE canonical path** | Classification forward goes through `classify_forward()` only |
+
+### 10.9 CLI Usage (v2)
+
+```bash
+# Plan fine-tuning (VRAM estimation only)
+apr finetune --model-size 500M --task classify --num-classes 5 \
+    --data corpus.jsonl --method lora --plan
+
+# Execute fine-tuning
+apr finetune model.safetensors --task classify --num-classes 5 \
+    --data corpus.jsonl --method lora --rank 16 -o adapter.apr
+
+# Merge adapter into base model
+apr finetune merge model.safetensors --adapter adapter.apr -o merged.apr
+```
+
+### 10.10 Runnable Example
+
+The `shell_safety_classify` example in entrenar demonstrates the full v2 pipeline:
+
+```bash
+# Quick demo with built-in corpus (no files needed)
+cargo run --example shell_safety_classify
+
+# With a JSONL corpus file
+cargo run --example shell_safety_classify -- /path/to/corpus.jsonl
+
+# Via apr-cli (Qwen2-0.5B config)
+apr finetune --task classify --model-size 0.5B --data corpus.jsonl
+```
+
+**Example output** (built-in demo corpus, 15 samples):
+
+```
+======================================================
+  Shell Safety Classification -- Fine-Tuning Demo
+  Powered by entrenar (training) + aprender (contracts)
+======================================================
+
+Corpus: 15 samples
+  [0] safe                 3 samples
+  [1] needs-quoting        3 samples
+  [2] non-deterministic    3 samples
+  [3] non-idempotent       3 samples
+  [4] unsafe               3 samples
+
+ClassifyPipeline:
+  Model: 64 hidden, 2 layers
+  LoRA: rank=4, alpha=4.0, 4 adapters
+  Classifier: 64->5 (325 params)
+  Total trainable: 2373 params
+```
+
+The example covers 6 stages:
+
+| Stage | Description |
+|-------|-------------|
+| 1. Corpus | Load from JSONL or built-in 15-sample demo |
+| 2. Pipeline | Build Transformer + LoRA + ClassificationHead |
+| 3. Classify | Forward pass on each sample (untrained baseline) |
+| 4. Train | 10-epoch training loop with loss monitoring |
+| 5. Merge | LoRA adapter merge into base weights |
+| 6. Production | Show Qwen2.5-Coder-0.5B config (1.1M params) |
+
+### 10.11 Corpus JSONL Format (v2)
+
+The classification corpus uses a simplified JSONL format:
+
+```json
+{"input": "#!/bin/bash\necho $HOME\n", "label": 1}
+{"input": "#!/bin/bash\neval \"$x\"\n", "label": 4}
+{"input": "#!/bin/sh\necho \"hello\"\n", "label": 0}
+```
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `input` | string | Shell script content |
+| `label` | integer | Safety class index (0=safe, 1=needs-quoting, 2=non-deterministic, 3=non-idempotent, 4=unsafe) |
+
+Labels map to `aprender::text::shell_vocab::SafetyClass`:
+- `SafetyClass::Safe` = 0
+- `SafetyClass::NeedsQuoting` = 1
+- `SafetyClass::NonDeterministic` = 2
+- `SafetyClass::NonIdempotent` = 3
+- `SafetyClass::Unsafe` = 4

+## 11. Future Work (v3+)
+
+### 11.1 Bashrs CLI Integration
+
+Add `bashrs classify` command that uses the trained model:
+```bash
+bashrs classify script.sh
+# Output: safe (confidence: 92.3%)
+```
+
+### 11.2 Multi-Label Classification
+
+Extend from single-label to multi-label (a script can be both non-deterministic
+AND needs-quoting). Use `BCEWithLogitsLoss` instead of `CrossEntropyLoss`.
+
+### 11.3 Cross-Format Models
+
+Train separate classifiers for Makefile and Dockerfile formats using the
+804 + 707 corpus entries respectively.
+
+### 11.4 Qwen3.5 Upgrade
+
+Upgrade from Qwen2.5-Coder-0.5B to Qwen3.5 with hybrid linear/quadratic
+attention, head_dim=256, vocab_size=248,320. Per `aprender/docs/specifications/qwen3.5-fine-tune.md`.

+## 13. v2.1 Work Tickets (Training Convergence + Corpus Pipeline)
+
+### SSC-017: Training Convergence (P0 CRITICAL)
+
+**Type**: Bug Fix
+**Priority**: P0 — STOP THE LINE
+**Status**: PLANNED
+**Complexity**: 8 (high)
+**Blocked by**: None
+**Blocks**: SSC-018, SSC-019, SSC-020
+
+**Root Cause Analysis**:
+
+`ClassifyPipeline::train_step()` only computes forward pass + loss. It never:
+1. Calls `backward()` on the loss tensor
+2. Calls `optimizer.step()` to update weights
+3. Takes `&mut self` (uses `&self`, cannot mutate)
+
+Result: loss stays flat at 1.6136 across all epochs (random init, no learning).
+
+**Fix — 4 changes required**:
+
+| # | Change | File | Description |
+|---|--------|------|-------------|
+| 1 | Add `optimizer` field | `classify_pipeline.rs` | `optimizer: AdamW` in `ClassifyPipeline` |
+| 2 | Implement full `train_step` | `classify_pipeline.rs` | `&mut self`: zero_grad → forward → loss → backward → optimizer.step |
+| 3 | Set `requires_grad=true` on LoRA A/B | `classify_pipeline.rs` | After LoRA creation, explicitly enable gradients |
+| 4 | Update example | `shell_safety_classify.rs` | Use `mut pipeline`, verify loss decreases |
+
+**Gradient flow (after fix)**:
+```
+token_ids → Transformer.forward_hidden() → hidden [seq, hidden]
+         → ClassificationHead.forward()  → logits [num_classes]
+         → cross_entropy_loss()           → loss [1]
+         → backward()                     → gradients on classifier weight/bias + LoRA A/B
+         → optimizer.step()               → parameter updates
+```
+
+**Acceptance Criteria**:
+- [ ] `train_step` takes `&mut self`, calls `backward()` + `optimizer.step()`
+- [ ] Loss decreases monotonically over 10 epochs on demo corpus
+- [ ] Final loss < 1.0 (from initial 1.6136)
+- [ ] All existing tests pass + new convergence test
+- [ ] F-CLASS-005 invariant maintained (loss always finite)

+
+**Type**: Feature
+**Priority**: P1
+**Status**: DONE (v2.1.0)
+**Complexity**: 5 (moderate)
+**Blocked by**: SSC-017 (DONE)
+**Blocks**: SSC-019
+
+**Description**:
+
+Added `derive_safety_label()` to bashrs corpus export. Applies priority-ordered
+decision tree to transpiled shell output to produce classification labels.
+
+**Decision tree** (cascading priority):
+```
+!transpiled OR !lint_clean       → Unsafe (4)
+!deterministic                   → NonDeterministic (2)
+mkdir without -p, rm without -f,
+ln -s without -f                 → NonIdempotent (3)
+unquoted $VAR in output          → NeedsQuoting (1)
+else                             → Safe (0)
+```
+
+**Implementation**:
+
+| Component | File | Description |
+|-----------|------|-------------|
+| `derive_safety_label()` | `rash/src/corpus/dataset.rs` | Decision tree function |
+| `has_non_idempotent_pattern()` | `rash/src/corpus/dataset.rs` | mkdir/rm/ln pattern detection |
+| `has_unquoted_variable()` | `rash/src/corpus/dataset.rs` | Quote-aware variable detection |
+| `line_has_unquoted_var()` | `rash/src/corpus/dataset.rs` | Single-line quote state machine |
+| `ClassificationRow` | `rash/src/corpus/dataset.rs` | Lightweight `{"input","label"}` struct |
+| `export_classification_jsonl()` | `rash/src/corpus/dataset.rs` | Entrenar-compatible export |
+| `ExportFormat::Classification` | `rash/src/corpus/dataset.rs` | New export format variant |
+| `DatasetExportFormat::Classification` | `rash/src/cli/args.rs` | CLI flag |
+| `safety_index`, `safety_label` | `DatasetRow` fields | Added to all export formats |
+
+**CLI usage**:
+```bash
+# Full dataset with safety fields
+bashrs corpus export-dataset --format jsonl
+
+# Classification-only JSONL for entrenar fine-tuning
+bashrs corpus export-dataset --format classification --output corpus.jsonl
+```
+
+**Output format** (classification):
+```json
+{"input":"#!/bin/sh\necho \"hello\"\n","label":0}
+{"input":"#!/bin/sh\necho $HOME\n","label":1}
+```
+
+**Acceptance Criteria**:
+- [x] `bashrs corpus export-dataset --format jsonl` includes `safety_label` and `safety_index`
+- [x] `bashrs corpus export-dataset --format classification` produces entrenar-compatible JSONL
+- [x] All entries get valid labels (0-4) via priority-ordered decision tree
+- [x] Failed transpilations filtered from classification export
+- [x] 108 tests pass (dataset + classification + safety label derivation)

+### SSC-019: bashrs classify CLI Command (P1) — DONE
+
+**Type**: Feature
+**Priority**: P1
+**Status**: DONE (v2.1.0)
+**Complexity**: 7 (high)
+**Blocked by**: SSC-017 (DONE), SSC-018 (DONE)
+
+**Description**:
+
+Added `bashrs classify script.sh` command that classifies shell scripts into
+5 safety categories using linter-based analysis with the same decision tree
+as the corpus export.
+
+**Architecture**:
+```
+script.sh → lint_shell() → SEC/DET/IDEM diagnostics
+          → derive_safety_label() → safety class (0-4)
+          → compute_confidence() → weighted confidence
+          → ClassifyResult → human/JSON output
+```
+
+**Implementation**:
+
+| Component | File | Description |
+|-----------|------|-------------|
+| `classify_command()` | `rash/src/cli/classify_commands.rs` | CLI entry point |
+| `classify_script()` | `rash/src/cli/classify_commands.rs` | Core classification logic |
+| `compute_confidence()` | `rash/src/cli/classify_commands.rs` | Confidence scoring |
+| `build_score_distribution()` | `rash/src/cli/classify_commands.rs` | Per-class probabilities |
+| `ClassifyResult` | `rash/src/cli/classify_commands.rs` | Serializable result struct |
+| `Commands::Classify` | `rash/src/cli/args.rs` | CLI argument definition |
+
+**Usage**:
+```bash
+bashrs classify script.sh
+# Output: safe (confidence: 95.0%)
+
+bashrs classify --json script.sh
+# Output: {"label":"safe","index":0,"confidence":0.95,"scores":[0.95,0.0125,...],
+#          "diagnostics":0,"has_security_issues":false,...}
+```
+
+**Acceptance Criteria**:
+- [x] `bashrs classify script.sh` outputs label + confidence
+- [x] `--json` flag outputs structured JSON with scores array
+- [x] Uses linter-based classification (SEC/DET/IDEM rules + pattern detection)
+- [x] All 5 classes detected correctly (verified via CLI and unit tests)
+- [x] Inference < 10ms per script (linter-based, no model weights needed)
+- [x] 11 unit tests pass

+
+**Type**: Feature
+**Priority**: P2
+**Status**: DONE (v2.1.0)
+**Complexity**: 5 (moderate)
+**Blocked by**: SSC-017 (DONE), SSC-018 (DONE)
+
+**Description**:
+
+Updated HuggingFace publication infrastructure for v2:
+
+**Implementation**:
+
+| Component | File | Description |
+|-----------|------|-------------|
+| `load_jsonl()` v2 | `aprender/examples/shell_safety_training.rs` | Auto-detects classification JSONL vs full dataset JSONL |

+
+### SSC-021: Multi-Label Classification (P3)
+
+**Type**: Enhancement
+**Priority**: P3
+**Status**: DONE
+**Complexity**: 6 (moderate-high)
+
+**Description**:
+
+Extend from single-label to multi-label (a script can be both non-deterministic
+AND needs-quoting). Add `BCEWithLogitsLoss` alongside `CrossEntropyLoss`.
+
+**Implementation**:
+
+| Component | File | What |
+|-----------|------|------|
+| `BCEWithLogitsLoss` | `entrenar/src/train/loss/bce_with_logits.rs` | Numerically stable BCE loss with autograd backward, sigmoid activation |
+| `MultiLabelSafetySample` | `entrenar/src/finetune/classification.rs` | Multi-hot label vector, single→multi conversion |
+| `multi_label_train_step` | `entrenar/src/finetune/classify_pipeline.rs` | BCE-based training step (independent per-class decisions) |
+| `load_multi_label_corpus` | `entrenar/src/finetune/classification.rs` | Auto-detect single/multi-label JSONL format |
+| `bce_with_logits_loss` | `entrenar/src/finetune/classification.rs` | Standalone BCE loss function for classification |
+| `--multi-label` flag | `bashrs/rash/src/cli/args.rs` | CLI flag for multi-label output |
+| `classify_script_multi_label` | `bashrs/rash/src/cli/classify_commands.rs` | Independent detection of ALL applicable classes |
+| `derive_multi_label` | `bashrs/rash/src/corpus/dataset.rs` | Multi-hot label derivation from corpus metadata |
+| `MultiLabelClassificationRow` | `bashrs/rash/src/corpus/dataset.rs` | JSONL row: `{"input":"...","labels":[...]}` |
+| `export_multi_label_classification_jsonl` | `bashrs/rash/src/corpus/dataset.rs` | Multi-label corpus export |
+| `multi-label-classification` format | `bashrs/rash/src/cli/args.rs` | CLI format variant for `corpus export-dataset` |
+
+**Usage**:
+
+```bash
+# Multi-label classify (all applicable labels)
+bashrs classify --multi-label script.sh
+# Output: non-deterministic + needs-quoting
+
+# Multi-label JSON output
+bashrs classify --multi-label --json script.sh
+# {"labels":["non-deterministic","needs-quoting"],"label_indices":[2,1],...}
+
+# Export multi-label corpus for entrenar
+bashrs corpus export-dataset --format multi-label-classification -o corpus.jsonl
+# {"input":"echo $RANDOM","labels":[0.0,1.0,1.0,0.0,0.0]}
+```
+
+**Tests**: 17 BCEWithLogitsLoss + 3 pipeline + 8 dataset + 7 classify = 35 tests
+
+**Key design**: BCEWithLogitsLoss uses numerically stable formula `max(x,0) - x*t + log(1+exp(-|x|))`
+with gradient `(σ(x) - target) / N`. Each class is an independent binary decision (sigmoid),
+unlike CrossEntropyLoss which uses softmax (mutually exclusive).

+### SSC-022: Cross-Format Models (P3)
+
+**Type**: Enhancement
+**Priority**: P3
+**Status**: DONE
+**Complexity**: 4 (low-moderate)
+
+**Description**:
+
+Extend `bashrs classify` to support Makefile and Dockerfile formats with
+format-specific lint rule mapping and safety taxonomy. Auto-detects format
+from file extension. Supports all three formats for corpus export.
+
+**Implementation**:
+
+| Component | File | What |
+|-----------|------|------|
+| `ClassifyFormat` enum | `rash/src/cli/args.rs` | Bash/Makefile/Dockerfile variants |
+| `--format` flag | `rash/src/cli/args.rs` | Force format override |

+| `lint_makefile` export | `rash/src/linter/mod.rs` | Re-export from rules module |
+
+**Format-specific rule mapping**:
+
+| Format | Security (SEC) | Determinism (DET) | Idempotency (IDEM) |
+|--------|---------------|-------------------|--------------------|
+| Bash | SEC001-SEC008 | DET001-DET006 | IDEM001+ |
+| Makefile | MAKE003 (shell injection) | MAKE001 (unsorted wildcard) | MAKE002 (missing .PHONY) |
+| Dockerfile | DOCKER001 (root), DOCKER006 (ADD) | DOCKER002 (unpinned tag) | — |
+
+**Usage**:
+
+```bash
+# Auto-detect format from extension
+bashrs classify script.sh           # → bash
+bashrs classify Makefile             # → makefile

+## 14. v2.2 Production Training Pipeline
+
+### 14.1 Motivation
+
+v2 is "DONE" in terms of infrastructure: the demo converges on 15 samples with a 64-hidden
+toy model. But no real Qwen2.5 weights have been loaded, no real 151K BPE tokenization,
+and no training on the full 26K-sample corpus. The adversarial data quality is excellent
+(1.8% mismatch on 8,000 samples) but has never been used for actual model training.
+
+**Goal**: Close the remaining gaps so `entrenar` can fine-tune Qwen2.5-Coder-0.5B on
+26K shell safety samples end-to-end, using ONLY the sovereign stack (trueno + aprender +
+entrenar + realizador). Then publish `paiml/shell-safety-classifier` to HuggingFace.
+
+### 14.2 Stack Audit
+
+| Layer | Crate | Version | Status |
+|-------|-------|---------|--------|
+| Compute | trueno | 0.15.0 | SIMD (5 backends) + GPU (wgpu). No gaps. |
+| ML Framework | aprender | 0.26.3 | Autograd, optimizers, loss, SafeTensors, APR format, HF Hub. **GAP: BPE tokenizer loading** |
+| Training | entrenar | 0.6.1 | Transformer, LoRA, QLoRA, AdamW, ClassifyPipeline. **GAPS: weight loading, batch training, training loop** |
+| Serving | realizador | 0.7.x | CUDA inference. Not needed for training phase. |
+| Contracts | provable-contracts | — | 96+ YAML contracts. 4 new contracts for gaps. |
+| Data | bashrs | 6.64.0 | 17,942 corpus + 8,000 adversarial = 26K samples. Ready. |

+**Contract**: `provable-contracts/contracts/aprender/tokenizer-loading-v1.yaml`
+**Blocked by**: —
+**Blocks**: SSC-026
+
+`BpeTokenizer::from_huggingface()` is declared but **not implemented**. Without this,
+we can only do byte-level tokenization which destroys all pretrained knowledge.
+
+**What exists**: `BpeConfig::qwen2()` preset (vocab_size=151,936), `BpeTokenizer` struct
+with all fields, merge-rule priority system.
+
+**What's missing**: Loading from HuggingFace `tokenizer.json` format (JSON with
+`model.vocab`, `model.merges`, `added_tokens`).
+
+**Key invariants** (F-TOK-001..008):
+- Roundtrip encode/decode
+- Special token ID preservation (151,643..151,645)
+- vocab_size == 151,936
+- Deterministic encoding
+- Full byte coverage (256 bytes)

+
+`Transformer::from_params()` creates random weights. No code maps HuggingFace tensor
+names (`model.layers.0.self_attn.q_proj.weight`) to entrenar's internal fields.
+
+**What exists**: `TransformerConfig::qwen2_0_5b()` (896h, 24L, 14 heads, 2 KV heads),
+SafeTensors parsing in aprender, `Transformer` struct.
+
+**What's missing**: `Transformer::from_safetensors(path)` that reads `.safetensors` files,
+maps tensor names, handles BF16→F32 conversion, validates shapes.
+
+**Key invariants** (F-WGT-001..009):
+- All 24 layers populated (no zeros)
+- No NaN/Inf
+- Shape match vs TransformerConfig
+- Embedding 151,936 × 896

+**Blocks**: SSC-026
+
+`ClassifyPipeline::train_step()` processes ONE sample. For 26K × 50 epochs = 1.3M
+individual forward+backward passes. Need mini-batching with gradient accumulation.
+
+**What's missing**: `train_batch()` with configurable batch_size, gradient accumulation,
+gradient clipping.
+
+**Key invariants** (F-BATCH-001..007):
+- Accumulated gradients equivalent to large-batch
+- Loss finite across all batches
+- Gradient norm bounded after clipping

+**Blocked by**: SSC-023, SSC-025
+**Blocks**: SSC-027
+
+No complete training loop with epoch management, validation split, checkpointing,
+and LR scheduling.
+
+**What's missing**: `ClassifyTrainer` struct that orchestrates: data loading → shuffle →
+batch → train → validate → log → checkpoint (dual APR + SafeTensors) → schedule LR.
+Checkpoints save both formats per Section 14.8. Final export produces APR (sovereign
+showcase) + SafeTensors (HuggingFace interop).
+
+**Key invariants** (F-LOOP-001..010):
+- EMA(loss) decreasing over training
+- Validation accuracy computed every epoch
+- Checkpoint restorable to same val_loss ± ε
+- Train/val split disjoint and frozen
+- Data shuffled per epoch (seeded RNG)

+
+The sovereign stack uses **both** APR and SafeTensors throughout the pipeline. APR is
+our native format; SafeTensors provides HuggingFace ecosystem interop.
+
+#### 14.8.1 Format Roles
+
+| Format | Role | Why |
+|--------|------|-----|
+| **APR** | Native sovereign format | Proves the stack is self-sufficient (no Python). Used by realizador for inference. Our showcase. |
+| **SafeTensors** | Ecosystem interop | Community standard. Anyone can load without installing our tooling. HuggingFace Hub native. |
+
+#### 14.8.2 Pipeline Flow
+
+```
+INGEST                    TRAINING                    EXPORT
+─────                     ────────                    ──────
+HuggingFace               Internal                    HuggingFace Hub
+SafeTensors ──┐                                  ┌──> adapter.safetensors
+              ├──> APR tensors in memory ──> ... ─┤
+tokenizer.json┘   (training, checkpoints)        ├──> shell-safety-classifier.apr
+                                                  └──> config.json, tokenizer.json, README.md
+```
+
+**Ingest**: `Transformer::from_safetensors()` loads HuggingFace weights, converts BF16→F32
+into in-memory tensors. This is a one-time import from the ecosystem.
+
+**Training**: All computation happens on in-memory tensors (trueno SIMD/GPU). Checkpoints
+save in **both** formats:
+- `checkpoint-epoch-{N}.apr` — primary, APR-native, used for resumption
+- `checkpoint-epoch-{N}.safetensors` — secondary, for interop/debugging
+
+**Export**: Final trained model published to HuggingFace with both formats:
+
+```
+paiml/shell-safety-classifier/
+  adapter.safetensors              ← LoRA adapter (community standard)
+  classifier_head.safetensors      ← Classification head weights
+  shell-safety-classifier.apr      ← Full model in APR format (sovereign showcase)
+  config.json                      ← Model architecture config
+  tokenizer.json                   ← Qwen2 BPE tokenizer
+  README.md                        ← Model card (Mitchell et al. 2019)
+```
+
+#### 14.8.3 Why Both (Not Either/Or)
+
+1. **APR proves sovereignty**: The entire train→infer pipeline works without Python,
+   without PyTorch, without HuggingFace transformers library. APR is the proof.
+
+2. **SafeTensors ensures adoption**: Researchers and practitioners can `pip install
+   safetensors` and load the model in 3 lines of Python. Zero friction.
+
+3. **Checkpoints need APR**: realizador loads APR natively for CUDA inference. If
+   checkpoints are only SafeTensors, we'd need a conversion step before serving.
+
+4. **APR validates the format**: Real-world fine-tuning is the best stress test for
+   APR's serialization, compression, and metadata capabilities. Dogfooding.
+
+#### 14.8.4 Implementation
+
+| Component | What | Where |
+|-----------|------|-------|
+| `save_checkpoint_dual()` | Saves both `.apr` and `.safetensors` for a checkpoint | `ClassifyTrainer` (SSC-026) |
+| `load_checkpoint()` | Loads from `.apr` (primary) with `.safetensors` fallback | `ClassifyTrainer` (SSC-026) |
+| `export_model()` | Final export of both formats + config + tokenizer | `ClassifyTrainer` (SSC-026) |
+| `--format apr,safetensors` | CLI flag for export format selection (default: both) | `apr-cli` (SSC-027) |
+
+### 14.9 Future: Qwen3.5 Upgrade Path
+
+Once v2.2 ships with Qwen2.5-Coder-0.5B, the upgrade path is:
+- SSC-028: Qwen3.5 hybrid attention in ClassifyPipeline
+- SSC-029: 248K vocab BPE tokenizer
+- SSC-030: Linear attention backward ops in trueno
+
+This is v3 scope — file when v2.2 is validated.

+# Unix Runtime Improvements Specification
+
+## Document Metadata
+
+| Field | Value |
+|-------|-------|
+| Version | 1.0.0 |
+| Status | Draft |
+| Created | 2026-01-06 |
+| Author | Claude Code |
+| Stakeholders | duende, trueno-zram, pepita, bashrs |
+
+---
+
+## 1. Executive Summary
+
+This specification defines Unix runtime improvements for bashrs to support the PAIML Sovereign AI Stack, with specific focus on Docker containerization, macOS compatibility, Bash/Zsh shell support, and daemon lifecycle management. Requirements are derived from three dependent projects: **duende** (daemon orchestration), **trueno-zram** (kernel-level memory compression), and **pepita** (distributed computing primitives).
+
+### Toyota Way Principles Applied
+
+> "The right process will produce the right results." — Taiichi Ohno
+
+This specification follows Toyota Production System principles:
+- **Jidoka** (自働化): Stop-the-line quality enforcement
+- **Genchi Genbutsu** (現地現物): Go and see for yourself (derived from actual project analysis)
+- **Kaizen** (改善): Continuous improvement through falsification testing
+- **Poka-yoke** (ポカヨケ): Mistake-proofing through type safety
+
+---
+
+## 2. Stakeholder Requirements
+
+### 2.1 Duende (Daemon Orchestration Framework)
+
+**Project**: Cross-platform daemon lifecycle management for Sovereign AI Stack
+
+#### Runtime Requirements
+
+| Category | Requirement | Priority |
+|----------|-------------|----------|
+| Process Management | Fork/exec via `/bin/sh` | P0 |
+| Signal Handling | SIGHUP, SIGTERM, SIGKILL, signal(0) | P0 |
+| Memory Locking | `mlock()`/`mlockall()` for swap deadlock prevention | P0 |
+| systemd Integration | Unit file generation and validation | P1 |
+| launchd Integration | plist generation for macOS | P1 |
+| Docker/OCI | Container runtime signal forwarding | P1 |
+| Capability Detection | CAP_IPC_LOCK, RLIMIT_MEMLOCK | P0 |
+
+#### Current Integration Points
+
+```makefile
+# From duende/Makefile (lines 138-163)
+bashrs-lint:
+    bashrs dockerfile lint docker/Dockerfile.*
+
+bashrs-gate:
+    # Enforces shell-free Docker images
+    @test -z "$$(find docker -name '*.sh' 2>/dev/null)"
+```
+
+#### Shell-Free Philosophy
+
+Duende enforces **zero shell scripts in production**:
+> "Pure Rust test runner - no bash scripts (bashrs compliant)"
+
+bashrs must validate that:
+1. Dockerfiles contain no `/bin/sh` invocations in final image
+2. No `.sh` files exist in `docker/` directories
+3. Generated unit files are POSIX-compliant
+
+### 2.2 trueno-zram (Kernel Memory Compression)
+
+**Project**: GPU-accelerated userspace ZRAM replacement
+
+#### Shell Script Requirements
+
+| Script | Lines | Purpose | bashrs Needs |
+|--------|-------|---------|--------------|
+| `test-swap-deadlock.sh` | 254 | DT-007 swap deadlock detection | procfs parsing |
+| `docker-test-harness.sh` | 690 | Test orchestration | Privileged Docker |
+| `falsification-runner.sh` | 476 | 100-point falsification matrix | JSON reporting |
+
+#### Kernel Operations Requiring Shell
+
+```bash
+# Module management
+modprobe ublk_drv
+lsmod | grep ublk_drv
+
+# Swap management
+mkswap /dev/ublkbN
+swapon -p 150 /dev/ublkbN
+swapoff /dev/ublkbN
+
+# Device operations
+blkdiscard /dev/ublkbN
+stat -c "%a" /dev/ublk-control
+
+# Filesystem operations
+mkfs.ext4 -F /dev/ublkbN
+mkfs.btrfs -f /dev/ublkbN
+mount /dev/ublkbN /mnt/test
+```
+
+#### Critical Path: DT-007 Swap Deadlock Detection
+
+```bash
+# From test-swap-deadlock.sh - process state inspection
+state=$(cat "/proc/$pid/stat" | awk '{print $3}')
+if [ "$state" = "D" ]; then
+    # state:D = uninterruptible sleep = deadlock risk
+    echo "DEADLOCK DETECTED"
+fi
+```
+
+### 2.3 pepita (Distributed Computing Primitives)
+
+**Project**: Minimal kernel interfaces for Sovereign AI workloads
+
+#### Runtime Requirements
+
+| Component | Requirement | Shell Impact |
+|-----------|-------------|--------------|
+| Binary Execution | `std::process::Command` | None (pure Rust) |
+| Task Scheduling | Multi-threaded work-stealing | None |
+| KVM Virtualization | ioctls via nix crate | None |
+| SIMD Detection | Runtime CPU feature detection | None |
+
+**Key Finding**: pepita has **zero shell dependencies** by design:
+- First-Principles Rust architecture
+- 100% auditable code path
+- No external executables required
+
+#### Integration Opportunity
+
+pepita's `pool` module could benefit from bashrs-generated init scripts:
+
+```rust
+// pepita/src/pool.rs - potential bashrs integration
+pub struct TaskPool {
+    scheduler: Scheduler,
+    executor: Executor,
+}
+
+// Generated init script validation
+// bashrs validate --pool-config pepita.toml
+```
+

+  <key>RunAtLoad</key>
+  <true/>
+</dict>
+</plist>
+```
+
+#### 4.2.2 mlock() on macOS

+
+#### 4.3.2 Bash Builtins Recognition
+
+SC2154 must recognize bash builtins (Issue #98):
+
+```bash
+BASH_BUILTINS = [
+  "EUID", "UID", "BASH_VERSION", "BASH_VERSINFO",
+  "HOSTNAME", "HOSTTYPE", "OSTYPE", "MACHTYPE",
+  "RANDOM", "SECONDS", "LINENO", "FUNCNAME",
+  "BASH_SOURCE", "BASH_LINENO", "PIPESTATUS", "GROUPS",
+  "PWD", "OLDPWD", "HOME", "PATH", "IFS",
+  "REPLY", "COMP_WORDS", "COMP_CWORD", "COMP_LINE"
+]
+```
+
+#### 4.3.3 Zsh-Specific Features
+
+```zsh
+# Zsh patterns bashrs should recognize
+typeset -A assoc_array           # Associative array declaration
+setopt NULL_GLOB                 # Glob options
+print -P "%~"                    # Prompt expansion
+autoload -Uz compinit            # Completion system
+```
+
+#### 4.3.4 Array Syntax (Issue #103)
+
+```bash
+# Patterns requiring parser support
+local arr=()                     # Empty array
+arr+=("item")                    # Array append
+${arr[@]}                        # Array expansion
+${#arr[@]}                       # Array length
+```
+
+### 4.4 Daemon Lifecycle Management
+
+#### 4.4.1 systemd Unit Generation (duende DP-002)
+
+```ini
+# Generated unit file template
+[Unit]
+Description=PAIML Daemon Service
+After=network.target
+
+[Service]
+Type=notify
+ExecStart=/usr/bin/daemon --config /etc/daemon/config.toml
+ExecReload=/bin/kill -HUP $MAINPID
+Restart=on-failure
+RestartSec=5
+LimitMEMLOCK=infinity
+
+[Install]
+WantedBy=multi-user.target
+```
+
+bashrs validation rules:
+- `SYSTEMD001`: Type must match daemon behavior
+- `SYSTEMD002`: ExecStart must be absolute path
+- `SYSTEMD003`: Restart policy appropriate for service type
+- `SYSTEMD004`: Resource limits specified
+
+#### 4.4.2 Signal Handling Validation
+
+```bash
+# Signal handler patterns to validate
+trap 'cleanup' EXIT
+trap 'reload_config' HUP
+trap 'graceful_shutdown' TERM INT
+trap '' PIPE                     # Ignore SIGPIPE
+```
+
+#### 4.4.3 PID File Management
+
+```bash
+# Patterns requiring validation
+PIDFILE="/var/run/daemon.pid"
+echo $$ > "$PIDFILE"             # Write PID
+kill -0 "$(cat "$PIDFILE")"      # Check if running
+rm -f "$PIDFILE"                 # Cleanup
+```

+## 6. Popperian Falsification Checklist
+
+> "The criterion of the scientific status of a theory is its falsifiability."
+> — Karl Popper, *Conjectures and Refutations* (1963)
+
+### Methodology
+
+Each test case is designed to **falsify** a claim about bashrs behavior. A passing test **fails to falsify** the hypothesis, providing provisional confidence. A failing test **successfully falsifies** the hypothesis, requiring immediate remediation.
+
+### 6.1 Parser Correctness (F001-F020)

+# TICKET-095: exec() String Validation Rejects Valid Shell Commands
+
+**Status**: 🟢 FIXED
+**Priority**: P0 - CRITICAL (Blocks whisper.apr QA)
+**Assignee**: Claude Code
+**Created**: 2026-01-20
+**GitHub Issue**: #95
+**Blocking**: whisper.apr WAPR-PERF-004 QA script
+
+## Problem Statement
+
+The `validate_string_literal()` function in `rash/src/validation/pipeline.rs` incorrectly rejects valid shell commands passed to `exec()`. This is a **false positive** that blocks legitimate bashrs usage.
+
+### Reproduction
+
+```rust
+// scripts/test.rs
+#[bashrs::main]
+fn main() {
+    exec("ldd /usr/bin/foo | grep cuda");  // REJECTED: "Pipe operator detected"
+    exec("cmd1 && cmd2");                   // REJECTED: "AND operator detected"
+}
+```
+
+```bash
+$ bashrs build scripts/test.rs -o test.sh
+error: Validation error: Pipe operator detected in string literal: 'ldd /usr/bin/foo | grep'
+```
+
+### Root Cause
+
+In `pipeline.rs:146-199`, the `validate_string_literal()` function checks ALL string literals for shell operators (`|`, `&&`, `||`, `;`), including strings that are **intentionally** shell commands passed to `exec()`.
+
+The security checks were designed to prevent command injection in interpolated strings, but they incorrectly apply to `exec()` arguments where shell operators are the **expected behavior**.
+
+```rust
+// Line 156: This pattern incorrectly flags exec("cmd1 && cmd2")
+("&& ", "AND operator detected in string literal"),
+
+// Line 183-199: This logic incorrectly flags exec("cmd1 | cmd2")
+if !is_formatting_string && s.contains("| ") { ... }
+```
+
+### Impact
+
+- **Blocks**: All bashrs scripts that use pipes or logical operators in `exec()`
+- **Severity**: P0 - Cannot build legitimate shell scripts
+- **Affected**: whisper.apr, aprender, and any project using bashrs for scripting
+
+## Success Criteria
+
+- [ ] `exec("cmd1 | cmd2")` compiles successfully
+- [ ] `exec("cmd1 && cmd2")` compiles successfully
+- [ ] `exec("cmd1 || cmd2")` compiles successfully
+- [ ] Security checks still apply to non-exec string literals
+- [ ] Shellshock protection still active
+- [ ] Command substitution `$(...)` in non-exec strings still flagged
+- [ ] All existing tests pass
+- [ ] New regression tests added
+- [ ] Property tests for edge cases
+
+## Proposed Fix
+
+**Option A (Recommended):** Context-aware validation
+
+Modify `validate_expr()` to track context and skip shell operator checks when inside an `exec()` call:
+
+```rust
+fn validate_function_call(&self, name: &str, args: &[Expr]) -> RashResult<()> {
+    let is_exec_context = name == "exec";
+    for arg in args {
+        if is_exec_context {
+            // Skip shell operator validation for exec() arguments
+            self.validate_expr_in_exec_context(arg)?;
+        } else {
+            self.validate_expr(arg)?;
+        }
+    }
+    Ok(())
+}
+```
+
+**Option B:** Allowlist approach
+
+Add exec-specific allowlist patterns:
+
+```rust
+fn validate_string_literal(&self, s: &str, context: ValidationContext) -> RashResult<()> {
+    if context == ValidationContext::ExecArgument {
+        // Only check for truly dangerous patterns like shellshock
+        return self.validate_exec_command(s);
+    }
+    // ... existing validation
+}
+```
+
+## Test Cases
+
+```rust
+#[test]
+fn test_exec_with_pipe_allowed() {
+    let source = r#"
+        fn main() {
+            exec("cat file | grep pattern");
+        }
+    "#;
+    assert!(compile(source).is_ok());
+}
+
+#[test]
+fn test_exec_with_and_allowed() {
+    let source = r#"
+        fn main() {
+            exec("cmd1 && cmd2");
+        }
+    "#;
+    assert!(compile(source).is_ok());
+}
+
+#[test]
+fn test_non_exec_string_with_pipe_still_flagged() {
+    let source = r#"
+        fn main() {
+            let x = "cat file | rm -rf /";  // NOT in exec - should flag
+            echo(x);
+        }
+    "#;
+    assert!(compile(source).is_err());
+}
+```
+
+## Toyota Way Analysis
+
+### Five Whys
+
+1. **Why did bashrs reject the script?** → Validation error on pipe operator
+2. **Why was pipe flagged?** → `validate_string_literal()` checks all strings
+3. **Why check all strings?** → Security against command injection
+4. **Why is this a false positive?** → `exec()` arguments ARE meant to be commands
+5. **Root cause?** → **No context-awareness in validation - exec() should be exempt**
+

+# OBS Studio Installer for Lambda Labs Workstations
+
+POSIX-compliant, deterministic, idempotent installer for OBS Studio optimized for NVIDIA RTX GPUs.
+
+## Problem
+
+The snap version of OBS Studio cannot access NVIDIA drivers due to sandbox restrictions:
+
+```
+libEGL warning: egl: failed to create dri2 screen
+MESA: error: ZINK: vkCreateInstance failed (VK_ERROR_INCOMPATIBLE_DRIVER)
+```
+
+This results in:
+- Software rendering instead of GPU acceleration
+- No NVENC hardware encoding
+- Poor performance on high-end workstations
+
+## Solution
+
+This installer:
+
+1. **Removes snap OBS** - Incompatible with NVIDIA driver sandboxing
+2. **Installs from official PPA** - Direct access to system NVIDIA drivers
+3. **Auto-detects GPU** - Configures optimal encoder settings per GPU generation
+4. **Creates optimized profile** - Pre-configured for high-quality recording
+

+## Purification Features
+
+This installer follows Rash purified script patterns:
+
+| Feature | Implementation |
+|---------|----------------|
+| **POSIX Compliant** | `#!/bin/sh` - works on dash, ash, bash |
+| **Deterministic** | No `$$`, `$RANDOM`, or timestamps |
+| **Idempotent** | `mkdir -p`, safe re-runs |
+| **Variables Quoted** | All variables properly quoted |
+| **Error Handling** | `set -euf`, explicit error checks |
+| **No Network for Version** | Uses PPA latest, no API calls |
+
+## Troubleshooting
+
+### NVENC Not Available
+
+Check NVIDIA driver:
+```bash
+nvidia-smi
+```
+
+Check OBS encoder list:
+```bash
+obs --help 2>&1 | grep -i encoder
+```
+
+### Screen Capture Not Working
+
+Ensure PipeWire is running:
+```bash
+systemctl --user status pipewire
+```
+
+### Profile Not Loading
+
+Verify config files:
+```bash
+ls -la ~/.config/obs-studio/basic/profiles/
+```
+
+## Uninstall
+
+```bash
+# Remove OBS
+sudo apt remove obs-studio
+
+# Remove PPA
+sudo add-apt-repository --remove ppa:obsproject/obs-studio
+
+# Remove config (optional)
+rm -rf ~/.config/obs-studio
+```

-// - May override system/user defaults
-// - Difficult to restore original value

-// Best Practices:

-//
-// Why POSIX sh only?
-// - Maximum portability (works everywhere: Alpine, Debian, BSD, macOS)
-// - Predictable behavior (no shell-specific quirks)
-// - Security: Simpler syntax = fewer attack vectors
-// - Standards-compliant: IEEE Std 1003.1-2001
-//
-// Bash extensions NOT GENERATED in purified output:

-// - $'...' (ANSI-C quoting) → printf with format strings
-// - let arithmetic → $((...)) (POSIX arithmetic)
-// - &> redirect → >file 2>&1 (POSIX redirection)
-// - [[ =~ ]] (regex match) → case or grep
-// - (( )) arithmetic → $((...))
-// - Arrays (declare -a) → use positional parameters or multiple variables

-// - cmd < file: Read stdin from file instead of terminal

-    // Purification strategies:
-    // 1. Numeric sequences: {1..10} → seq 1 10 or for i in $(seq 1 10)
-    // 2. Letter sequences: {a..e} → echo a b c d e (explicit)

-// Types: Numeric sequences {1..10}, letter sequences {a..z}, comma lists {foo,bar}
-// Nested: {a,b}{1,2} creates Cartesian product (a1 a2 b1 b2)
-// Introduced: Bash 3.0 (2004), not in POSIX specification
-// POSIX alternatives: seq command, for loops, explicit lists
-// Purification: {1..10} → seq 1 10, {foo,bar} → echo foo bar, nested → loops
-// Common uses: mkdir {src,tests,docs}, cp file{,.bak}, touch file{1..5}.txt
-// Best practice: Use seq for ranges, explicit lists for small sets, avoid in portable scripts

-// ============================================================================
-// BUILTIN-005: cd command (POSIX builtin)
-// ============================================================================
-// Task: Document cd (change directory) builtin command
-// Reference: GNU Bash Manual Section 4.1 (Bourne Shell Builtins)
-// POSIX: cd is POSIX-COMPLIANT (SUPPORTED)
-//
-// Syntax:
-//   cd [directory]
-//   cd -           # Go to previous directory ($OLDPWD)
-//   cd             # Go to home directory ($HOME)
-//   cd ~           # Go to home directory (tilde expansion)
-//   cd ~/path      # Go to home/path
-//
-// POSIX Compliance:
-//   SUPPORTED: cd /path, cd -, cd (no args), cd ~, cd ~/path
-//   SUPPORTED: Uses $HOME, $OLDPWD, $PWD environment variables
-//   SUPPORTED: Returns exit status 0 (success) or 1 (failure)
-//   SUPPORTED: Updates $PWD and $OLDPWD automatically
-//
-// Bash Extensions:
-//   -L (default): Follow symbolic links
-//   -P: Use physical directory structure (resolve symlinks)
-//   -e: Exit if cd fails (with -P)
-//   -@: Present extended attributes as directory (rare)
-//   CDPATH: Search path for directories (bash/ksh extension)
-//
-// bashrs Support:
-//   SUPPORTED: Basic cd /path navigation
-//   SUPPORTED: cd - (previous directory via $OLDPWD)
-//   SUPPORTED: cd (no args, go to $HOME)
-//   SUPPORTED: cd ~ (tilde expansion to $HOME)
-//   SUPPORTED: cd ~/path (tilde expansion)
-//   NOT SUPPORTED: -L, -P, -e, -@ flags (bash extensions)
-//   NOT SUPPORTED: CDPATH search path (bash/ksh extension)
-//
-// Rust Mapping:
-//   cd /path → std::env::set_current_dir("/path")
-//   cd -     → std::env::set_current_dir(&env::var("OLDPWD"))
-//   cd       → std::env::set_current_dir(&env::home_dir())
-//   cd ~     → std::env::set_current_dir(&env::home_dir())
-//
-// Purified Bash:
-//   cd /path     → cd "/path"     (quote path for safety)
-//   cd "$dir"    → cd "$dir"      (preserve quoting)
-//   cd -         → cd -           (POSIX supported)
-//   cd           → cd             (POSIX supported)
-//   cd ~         → cd ~           (POSIX tilde expansion)
-//   cd -L /path  → cd "/path"     (strip bash-specific flags)
-//   cd -P /path  → cd "/path"     (strip bash-specific flags)
-//
-// Environment Variables:
-//   $PWD: Current working directory (updated by cd)
-//   $OLDPWD: Previous working directory (updated by cd)
-//   $HOME: Home directory (used by cd with no args)
-//   $CDPATH: Search path (bash/ksh extension, not POSIX)
-//
-// Exit Status:
-//   0: Success (directory changed)
-//   1: Failure (directory doesn't exist, no permissions, etc.)
-//
-// Common Use Cases:
-//   1. Navigate to directory: cd /tmp
-//   2. Go to home directory: cd or cd ~
-//   3. Go to previous directory: cd -
-//   4. Navigate to subdirectory: cd src/main
-//   5. Navigate to parent directory: cd ..
-//   6. Navigate with variable: cd "$PROJECT_DIR"
-//
-// Edge Cases:
-//   1. cd with no args → go to $HOME
-//   2. cd - with no $OLDPWD → error (variable not set)
-//   3. cd to nonexistent directory → returns 1, prints error
-//   4. cd with permissions denied → returns 1, prints error
-//   5. cd to symlink → follows symlink by default
-//   6. cd with spaces → requires quoting: cd "My Documents"
-//
-// Best Practices:
-//   1. Always quote paths with spaces: cd "$dir"
-//   2. Check exit status for error handling: cd /tmp || exit 1
-//   3. Use cd - to toggle between two directories
-//   4. Use absolute paths for determinism
-//   5. Avoid CDPATH in portable scripts (not POSIX)

-// BUILTIN-009: exit command (POSIX builtin)
-// ============================================================================
-// Task: Document exit (terminate shell) builtin command
-// Reference: GNU Bash Manual Section 4.1 (Bourne Shell Builtins)
-// POSIX: exit is POSIX-COMPLIANT (SUPPORTED)
-//
-// Syntax:
-//   exit [n]
-//   exit 0           # Exit with success (status 0)
-//   exit 1           # Exit with failure (status 1)
-//   exit             # Exit with status of last command ($?)
-//   exit $?          # Explicit exit with last command status
-//
-// POSIX Compliance:
-//   SUPPORTED: exit [n] where n is 0-255
-//   SUPPORTED: exit with no args (uses $? from last command)
-//   SUPPORTED: Exit status 0 = success, non-zero = failure
-//   SUPPORTED: In functions, exit terminates entire script (not just function)
-//   SUPPORTED: In subshells, exit terminates only the subshell
-//
-// Exit Status Conventions (POSIX):
-//   0: Success (command completed successfully)
-//   1: General errors (catchall for miscellaneous errors)
-//   2: Misuse of shell builtins (missing keyword or command)
-//   126: Command invoked cannot execute (permission problem)
-//   127: Command not found (illegal command)
-//   128: Invalid argument to exit (non-numeric or out of range)
-//   128+N: Fatal error signal N (e.g., 130 = 128+2 for SIGINT/Ctrl-C)
-//   255: Exit status out of range (exit takes only 0-255)
-//
-// Bash Extensions:
-//   exit with value >255: Wraps modulo 256 (exit 256 becomes 0)
-//   exit with negative value: Wraps modulo 256 (exit -1 becomes 255)
-//   exit in trap handlers: Specific behaviors in various traps
-//
-// bashrs Support:
-//   SUPPORTED: exit [n] where n is 0-255
-//   SUPPORTED: exit with no args (uses $?)
-//   SUPPORTED: Standard exit status conventions
-//   NOT SUPPORTED: exit >255 (bash wrapping behavior)
-//   NOT SUPPORTED: exit with negative values (bash wrapping behavior)
-//
-// Rust Mapping:
-//   exit 0 → std::process::exit(0)
-//   exit 1 → std::process::exit(1)
-//   exit $? → std::process::exit(last_exit_status)
-//   exit → std::process::exit(last_exit_status)
-//
-// Purified Bash:
-//   exit 0 → exit 0 (POSIX supported)
-//   exit 1 → exit 1 (POSIX supported)
-//   exit → exit (POSIX supported, uses $?)
-//   exit 256 → exit 0 (normalize to 0-255 range)
-//   exit -1 → exit 255 (normalize to 0-255 range)
-//
-// Exit vs Return:
-//   exit: Terminates entire script (even from function)
-//   return: Returns from function only (function-local)
-//   In script: exit terminates script
-//   In function: exit terminates script, return returns from function
-//   In subshell: exit terminates subshell only
-//
-// Common Use Cases:
-//   1. Success exit: exit 0 (at end of script)
-//   2. Error exit: exit 1 (on error conditions)
-//   3. Conditional exit: [ -z "$VAR" ] && exit 1
-//   4. Exit with last status: command || exit
-//   5. Exit with custom code: exit 2 (for specific error types)
-//   6. Early return: if [ error ]; then exit 1; fi
-//
-// Edge Cases:
-//   1. exit with no args → uses $? from last command
-//   2. exit >255 → bash wraps modulo 256 (exit 256 = 0)
-//   3. exit <0 → bash wraps modulo 256 (exit -1 = 255)
-//   4. exit in subshell → terminates subshell only, not parent
-//   5. exit in function → terminates entire script, not just function
-//   6. exit in trap → depends on trap type (EXIT, ERR, etc.)
-//
-// Best Practices:
-//   1. Use exit 0 for success at end of script
-//   2. Use exit 1 for general errors
-//   3. Use specific exit codes (2-125) for different error types
-//   4. Document exit codes in script header
-//   5. Use return (not exit) in functions to avoid terminating script
-//   6. Check $? before exit to propagate error codes
-//   7. Avoid exit codes >125 (reserved for signals and special meanings)

-// ============================================================================
-// BUILTIN-010: export command (POSIX builtin)
-// ============================================================================
-// Task: Document export (set environment variables) builtin command
-// Reference: GNU Bash Manual Section 4.1 (Bourne Shell Builtins)
-// POSIX: export is POSIX-COMPLIANT (SUPPORTED)
-//
-// Syntax:
-//   export VAR=value      # Set and export variable
-//   export VAR            # Export existing variable
-//   export VAR="value"    # Set and export with quotes
-//   export -n VAR         # Remove export attribute (bash extension)
-//   export -p             # Print all exported variables
-//
-// POSIX Compliance:
-//   SUPPORTED: export VAR=value (set and export)
-//   SUPPORTED: export VAR (export existing variable)
-//   SUPPORTED: export with quoting (export VAR="value with spaces")
-//   SUPPORTED: export -p (print exported variables)
-//   SUPPORTED: Multiple exports (export VAR1=val1 VAR2=val2)
-//
-// Bash Extensions:
-//   export -n VAR: Remove export attribute (unexport variable)
-//   export -f func: Export function definitions (bash-specific)
-//   Arrays: export ARRAY (bash arrays, not POSIX)
-//
-// bashrs Support:
-//   SUPPORTED: export VAR=value (set and export)
-//   SUPPORTED: export VAR (export existing variable)
-//   SUPPORTED: export with quoting
-//   SUPPORTED: Multiple exports in one command
-//   NOT SUPPORTED: export -n (unexport, bash extension)
-//   NOT SUPPORTED: export -f (function export, bash extension)
-//   NOT SUPPORTED: Array exports (bash extension)
-//
-// Rust Mapping:
-//   export VAR=value → std::env::set_var("VAR", "value")
-//   export VAR → std::env::set_var("VAR", existing_value)
-//   export -p → std::env::vars() (iterate and print)
-//
-// Purified Bash:
-//   export VAR=value → export VAR=value (POSIX supported)
-//   export VAR → export VAR (POSIX supported)
-//   export VAR="value" → export VAR="value" (preserve quoting)
-//   export -n VAR → unset VAR (remove variable, closest POSIX equivalent)
-//   export -f func → # Not supported (remove from purified scripts)
-//
-// export vs Variable Assignment:
-//   VAR=value: Sets variable in current shell only (not exported)
-//   export VAR=value: Sets variable and exports to child processes
-//   Child processes inherit exported variables
-//   Non-exported variables are local to current shell
-//
-// Common Use Cases:
-//   1. Set PATH: export PATH="/usr/local/bin:$PATH"
-//   2. Set config: export CONFIG_FILE="/etc/app.conf"
-//   3. Export existing: VAR=value; export VAR
-//   4. Multiple exports: export VAR1=val1 VAR2=val2
-//   5. Print exports: export -p (list all exported variables)
-//   6. Build environment: export CC=gcc CXX=g++ CFLAGS="-O2"
-//
-// Edge Cases:
-//   1. export with no value → exports existing variable
-//   2. export nonexistent → creates empty exported variable
-//   3. export with spaces → requires quoting: export VAR="value with spaces"
-//   4. export in subshell → only affects subshell, not parent
-//   5. export in function → affects entire script (exported globally)
-//   6. Overwrite exports → later export overwrites previous value
-//
-// Best Practices:
-//   1. Quote values with spaces: export VAR="value with spaces"
-//   2. Use uppercase for exported variables (convention)
-//   3. Document required environment variables in script header
-//   4. Check if variable is set before using: ${VAR:-default}
-//   5. Use export for variables needed by child processes
-//   6. Avoid exporting sensitive data (passwords, tokens)

-// BUILTIN-011: pwd command (POSIX builtin)
-// ============================================================================
-// Task: Document pwd (print working directory) builtin command
-// Reference: GNU Bash Manual Section 4.1 (Bourne Shell Builtins)
-// POSIX: pwd is POSIX-COMPLIANT (SUPPORTED)
-//
-// Syntax:
-//   pwd               # Print current working directory
-//   pwd -L            # Logical path (follow symlinks, default)
-//   pwd -P            # Physical path (resolve symlinks)
-//
-// POSIX Compliance:
-//   SUPPORTED: pwd (print current working directory)
-//   SUPPORTED: pwd -L (logical path, follows symlinks)
-//   SUPPORTED: pwd -P (physical path, resolves symlinks)
-//   SUPPORTED: Uses $PWD environment variable
-//   SUPPORTED: Returns 0 on success, non-zero on error
-//
-// Bash Extensions:
-//   None - pwd is fully POSIX-compliant
-//
-// bashrs Support:
-//   SUPPORTED: pwd (basic form)
-//   SUPPORTED: pwd -L (logical path, default behavior)
-//   SUPPORTED: pwd -P (physical path, resolve symlinks)
-//   SUPPORTED: $PWD environment variable
-//
-// Rust Mapping:
-//   pwd → std::env::current_dir()
-//   pwd -L → std::env::current_dir() (logical path)
-//   pwd -P → std::fs::canonicalize(std::env::current_dir()) (physical path)
-//
-// Purified Bash:
-//   pwd → pwd (POSIX supported)
-//   pwd -L → pwd -L (POSIX supported)
-//   pwd -P → pwd -P (POSIX supported)
-//
-// pwd vs $PWD:
-//   pwd: Command that prints current directory
-//   $PWD: Environment variable containing current directory
-//   $PWD is updated by cd command
-//   pwd retrieves current directory from system
-//   In most cases: pwd output == $PWD value
-//
-// Common Use Cases:
-//   1. Get current directory: current=$(pwd)
-//   2. Save and restore: old_pwd=$(pwd); cd /tmp; cd "$old_pwd"
-//   3. Relative paths: echo "Working in $(pwd)"
-//   4. Scripts: SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)"
-//   5. Resolve symlinks: physical_path=$(pwd -P)
-//   6. Logical path: logical_path=$(pwd -L)
-//
-// Edge Cases:
-//   1. Directory deleted: pwd may fail if CWD deleted
-//   2. No permissions: pwd may fail if no read permissions on path
-//   3. Symlinks: pwd -L shows symlink, pwd -P resolves symlink
-//   4. $PWD mismatch: pwd always accurate, $PWD can be modified
-//   5. Chroot: pwd shows path relative to chroot
-//
-// Best Practices:
-//   1. Use pwd for portability (works in all POSIX shells)
-//   2. Use $PWD for efficiency (no subprocess spawn)
-//   3. Use pwd -P to resolve symlinks for canonical paths
-//   4. Save pwd before changing directories for restoration
-//   5. Quote pwd output in assignments: dir="$(pwd)"
-//

-    // sh (POSIX): "h" (only hashall, no bash extensions)
-    //
-    // WHY NOT SUPPORTED:
-    // 1. Runtime-specific (value depends on how shell was invoked)
-    // 2. Non-deterministic (different shells = different flags)
-    // 3. Shell-dependent (bash has different flags than sh/dash)
-    // 4. Implementation detail (exposes internal shell state)
-    // 5. Not needed for pure scripts (purified scripts don't rely on shell modes)
-    //
-    // CRITICAL: $- exposes runtime configuration, not script logic
-    // Purified scripts should be EXPLICIT about behavior (not rely on shell flags)

-    // POSIX COMPLIANCE:
-    // $- is POSIX SUPPORTED (Single Unix Specification)
-    // However, the FLAGS DIFFER between shells:
-    // - bash: himBH (many extensions)
-    // - sh: h (minimal)
-    // - dash: h (minimal)
-    //
-    // PURIFICATION STRATEGY:
-    // 1. Remove $- entirely (RECOMMENDED)
-    // 2. Replace with explicit option checks (if absolutely needed)
-    // 3. Use set -e explicitly (don't check for "e" in $-)
-    // 4. Document why removed (not needed in purified scripts)
-    //
-    // WHEN $- IS USED:
-    // 1. Debugging: echo "Shell options: $-"
-    // 2. Checking interactive: case "$-" in *i*) interactive mode
-    // 3. Checking error mode: case "$-" in *e*) will exit on error

-    // INPUT/OUTPUT FLAGS:

-    // f - Disable filename expansion/globbing (set -f, noglob)
-    // a - Auto-export all variables (set -a, allexport)
-    // h - Hash commands as looked up (set -h, hashall)

+// - Stack persists across commands in same session
+// - Interactive convenience feature

+// POSIX alternatives: seq command, for loops, explicit lists
+// Purification: {1..10} → seq 1 10, {foo,bar} → echo foo bar, nested → loops
+// Common uses: mkdir {src,tests,docs}, cp file{,.bak}, touch file{1..5}.txt

+// ============================================================================
+// BUILTIN-005: cd command (POSIX builtin)
+// ============================================================================
+// Task: Document cd (change directory) builtin command
+// Reference: GNU Bash Manual Section 4.1 (Bourne Shell Builtins)
+// POSIX: cd is POSIX-COMPLIANT (SUPPORTED)
+//
+// Syntax:
+//   cd [directory]
+//   cd -           # Go to previous directory ($OLDPWD)
+//   cd             # Go to home directory ($HOME)
+//   cd ~           # Go to home directory (tilde expansion)
+//   cd ~/path      # Go to home/path
+//
+// POSIX Compliance:
+//   SUPPORTED: cd /path, cd -, cd (no args), cd ~, cd ~/path
+//   SUPPORTED: Uses $HOME, $OLDPWD, $PWD environment variables
+//   SUPPORTED: Returns exit status 0 (success) or 1 (failure)
+//   SUPPORTED: Updates $PWD and $OLDPWD automatically
+//
+// Bash Extensions:
+//   -L (default): Follow symbolic links
+//   -P: Use physical directory structure (resolve symlinks)
+//   -e: Exit if cd fails (with -P)
+//   -@: Present extended attributes as directory (rare)
+//   CDPATH: Search path for directories (bash/ksh extension)
+//
+// bashrs Support:
+//   SUPPORTED: Basic cd /path navigation
+//   SUPPORTED: cd - (previous directory via $OLDPWD)
+//   SUPPORTED: cd (no args, go to $HOME)
+//   SUPPORTED: cd ~ (tilde expansion to $HOME)
+//   SUPPORTED: cd ~/path (tilde expansion)
+//   NOT SUPPORTED: -L, -P, -e, -@ flags (bash extensions)
+//   NOT SUPPORTED: CDPATH search path (bash/ksh extension)
+//
+// Rust Mapping:
+//   cd /path → std::env::set_current_dir("/path")
+//   cd -     → std::env::set_current_dir(&env::var("OLDPWD"))
+//   cd       → std::env::set_current_dir(&env::home_dir())
+//   cd ~     → std::env::set_current_dir(&env::home_dir())
+//
+// Purified Bash:
+//   cd /path     → cd "/path"     (quote path for safety)
+//   cd "$dir"    → cd "$dir"      (preserve quoting)
+//   cd -         → cd -           (POSIX supported)
+//   cd           → cd             (POSIX supported)
+//   cd ~         → cd ~           (POSIX tilde expansion)
+//   cd -L /path  → cd "/path"     (strip bash-specific flags)
+//   cd -P /path  → cd "/path"     (strip bash-specific flags)
+//
+// Environment Variables:
+//   $PWD: Current working directory (updated by cd)
+//   $OLDPWD: Previous working directory (updated by cd)
+//   $HOME: Home directory (used by cd with no args)
+//   $CDPATH: Search path (bash/ksh extension, not POSIX)
+//
+// Exit Status:
+//   0: Success (directory changed)
+//   1: Failure (directory doesn't exist, no permissions, etc.)
+//
+// Common Use Cases:
+//   1. Navigate to directory: cd /tmp
+//   2. Go to home directory: cd or cd ~
+//   3. Go to previous directory: cd -
+//   4. Navigate to subdirectory: cd src/main
+//   5. Navigate to parent directory: cd ..
+//   6. Navigate with variable: cd "$PROJECT_DIR"
+//
+// Edge Cases:
+//   1. cd with no args → go to $HOME
+//   2. cd - with no $OLDPWD → error (variable not set)
+//   3. cd to nonexistent directory → returns 1, prints error
+//   4. cd with permissions denied → returns 1, prints error
+//   5. cd to symlink → follows symlink by default
+//   6. cd with spaces → requires quoting: cd "My Documents"
+//
+// Best Practices:
+//   1. Always quote paths with spaces: cd "$dir"
+//   2. Check exit status for error handling: cd /tmp || exit 1
+//   3. Use cd - to toggle between two directories
+//   4. Use absolute paths for determinism
+//   5. Avoid CDPATH in portable scripts (not POSIX)

+// BUILTIN-009: exit command (POSIX builtin)
+// ============================================================================
+// Task: Document exit (terminate shell) builtin command
+// Reference: GNU Bash Manual Section 4.1 (Bourne Shell Builtins)
+// POSIX: exit is POSIX-COMPLIANT (SUPPORTED)
+//
+// Syntax:
+//   exit [n]
+//   exit 0           # Exit with success (status 0)
+//   exit 1           # Exit with failure (status 1)
+//   exit             # Exit with status of last command ($?)
+//   exit $?          # Explicit exit with last command status
+//
+// POSIX Compliance:
+//   SUPPORTED: exit [n] where n is 0-255
+//   SUPPORTED: exit with no args (uses $? from last command)
+//   SUPPORTED: Exit status 0 = success, non-zero = failure
+//   SUPPORTED: In functions, exit terminates entire script (not just function)
+//   SUPPORTED: In subshells, exit terminates only the subshell
+//
+// Exit Status Conventions (POSIX):
+//   0: Success (command completed successfully)
+//   1: General errors (catchall for miscellaneous errors)
+//   2: Misuse of shell builtins (missing keyword or command)
+//   126: Command invoked cannot execute (permission problem)
+//   127: Command not found (illegal command)
+//   128: Invalid argument to exit (non-numeric or out of range)
+//   128+N: Fatal error signal N (e.g., 130 = 128+2 for SIGINT/Ctrl-C)
+//   255: Exit status out of range (exit takes only 0-255)
+//
+// Bash Extensions:
+//   exit with value >255: Wraps modulo 256 (exit 256 becomes 0)
+//   exit with negative value: Wraps modulo 256 (exit -1 becomes 255)
+//   exit in trap handlers: Specific behaviors in various traps
+//
+// bashrs Support:
+//   SUPPORTED: exit [n] where n is 0-255
+//   SUPPORTED: exit with no args (uses $?)
+//   SUPPORTED: Standard exit status conventions
+//   NOT SUPPORTED: exit >255 (bash wrapping behavior)
+//   NOT SUPPORTED: exit with negative values (bash wrapping behavior)
+//
+// Rust Mapping:
+//   exit 0 → std::process::exit(0)
+//   exit 1 → std::process::exit(1)
+//   exit $? → std::process::exit(last_exit_status)
+//   exit → std::process::exit(last_exit_status)
+//
+// Purified Bash:
+//   exit 0 → exit 0 (POSIX supported)
+//   exit 1 → exit 1 (POSIX supported)
+//   exit → exit (POSIX supported, uses $?)
+//   exit 256 → exit 0 (normalize to 0-255 range)
+//   exit -1 → exit 255 (normalize to 0-255 range)
+//
+// Exit vs Return:
+//   exit: Terminates entire script (even from function)
+//   return: Returns from function only (function-local)
+//   In script: exit terminates script
+//   In function: exit terminates script, return returns from function
+//   In subshell: exit terminates subshell only
+//
+// Common Use Cases:
+//   1. Success exit: exit 0 (at end of script)
+//   2. Error exit: exit 1 (on error conditions)
+//   3. Conditional exit: [ -z "$VAR" ] && exit 1
+//   4. Exit with last status: command || exit
+//   5. Exit with custom code: exit 2 (for specific error types)
+//   6. Early return: if [ error ]; then exit 1; fi
+//
+// Edge Cases:
+//   1. exit with no args → uses $? from last command
+//   2. exit >255 → bash wraps modulo 256 (exit 256 = 0)
+//   3. exit <0 → bash wraps modulo 256 (exit -1 = 255)
+//   4. exit in subshell → terminates subshell only, not parent
+//   5. exit in function → terminates entire script, not just function
+//   6. exit in trap → depends on trap type (EXIT, ERR, etc.)
+//
+// Best Practices:
+//   1. Use exit 0 for success at end of script
+//   2. Use exit 1 for general errors
+//   3. Use specific exit codes (2-125) for different error types
+//   4. Document exit codes in script header
+//   5. Use return (not exit) in functions to avoid terminating script
+//   6. Check $? before exit to propagate error codes
+//   7. Avoid exit codes >125 (reserved for signals and special meanings)

+// Task: Document export (set environment variables) builtin command
+// Reference: GNU Bash Manual Section 4.1 (Bourne Shell Builtins)
+// POSIX: export is POSIX-COMPLIANT (SUPPORTED)
+//
+// Syntax:
+//   export VAR=value      # Set and export variable
+//   export VAR            # Export existing variable
+//   export VAR="value"    # Set and export with quotes
+//   export -n VAR         # Remove export attribute (bash extension)

+//   SUPPORTED: export with quoting (export VAR="value with spaces")
+//   SUPPORTED: export -p (print exported variables)
+//   SUPPORTED: Multiple exports (export VAR1=val1 VAR2=val2)
+//
+// Bash Extensions:
+//   export -n VAR: Remove export attribute (unexport variable)
+//   export -f func: Export function definitions (bash-specific)
+//   Arrays: export ARRAY (bash arrays, not POSIX)
+//
+// bashrs Support:
+//   SUPPORTED: export VAR=value (set and export)
+//   SUPPORTED: export VAR (export existing variable)
+//   SUPPORTED: export with quoting
+//   SUPPORTED: Multiple exports in one command
+//   NOT SUPPORTED: export -n (unexport, bash extension)
+//   NOT SUPPORTED: export -f (function export, bash extension)
+//   NOT SUPPORTED: Array exports (bash extension)
+//
+// Rust Mapping:
+//   export VAR=value → std::env::set_var("VAR", "value")
+//   export VAR → std::env::set_var("VAR", existing_value)
+//   export -p → std::env::vars() (iterate and print)
+//
+// Purified Bash:
+//   export VAR=value → export VAR=value (POSIX supported)
+//   export VAR → export VAR (POSIX supported)
+//   export VAR="value" → export VAR="value" (preserve quoting)
+//   export -n VAR → unset VAR (remove variable, closest POSIX equivalent)
+//   export -f func → # Not supported (remove from purified scripts)
+//
+// export vs Variable Assignment:
+//   VAR=value: Sets variable in current shell only (not exported)
+//   export VAR=value: Sets variable and exports to child processes
+//   Child processes inherit exported variables
+//   Non-exported variables are local to current shell
+//
+// Common Use Cases:
+//   1. Set PATH: export PATH="/usr/local/bin:$PATH"
+//   2. Set config: export CONFIG_FILE="/etc/app.conf"
+//   3. Export existing: VAR=value; export VAR
+//   4. Multiple exports: export VAR1=val1 VAR2=val2
+//   5. Print exports: export -p (list all exported variables)
+//   6. Build environment: export CC=gcc CXX=g++ CFLAGS="-O2"
+//
+// Edge Cases:
+//   1. export with no value → exports existing variable
+//   2. export nonexistent → creates empty exported variable
+//   3. export with spaces → requires quoting: export VAR="value with spaces"
+//   4. export in subshell → only affects subshell, not parent
+//   5. export in function → affects entire script (exported globally)
+//   6. Overwrite exports → later export overwrites previous value
+//
+// Best Practices:
+//   1. Quote values with spaces: export VAR="value with spaces"
+//   2. Use uppercase for exported variables (convention)
+//   3. Document required environment variables in script header
+//   4. Check if variable is set before using: ${VAR:-default}
+//   5. Use export for variables needed by child processes
+//   6. Avoid exporting sensitive data (passwords, tokens)

+// PARAM-SPEC-006: $- (Shell Options) Purification
+// ============================================================================
+
+// DOCUMENTATION: $- (shell options) is NOT SUPPORTED (LOW priority purification)
+//
+// $-: Special parameter that expands to current shell option flags
+// Contains single letters representing active shell options
+// Set by: Shell at startup, modified by set command
+//
+// WHAT $- CONTAINS (each letter = an active option):
+// h: hashall, i: interactive, m: monitor mode, B: brace expansion,
+// H: history substitution, s: read from stdin, c: read from -c arg,
+// e: exit on error, u: error on unset vars, x: print commands,
+// v: print input lines, n: no execution, f: no globbing,
+// a: auto-export all, t: exit after one command
+//
+// EXAMPLE VALUES:
+// Interactive bash: "himBH", Script: "hB", set -e script: "ehB", sh: "h"
+//
+// WHY NOT SUPPORTED:
+// 1. Runtime-specific (value depends on how shell was invoked)
+// 2. Non-deterministic (different shells = different flags)
+// 3. Shell-dependent (bash has different flags than sh/dash)
+// 4. Implementation detail (exposes internal shell state)
+// 5. Not needed for pure scripts (purified scripts don't rely on shell modes)
+//
+// POSIX COMPLIANCE: $- is POSIX SUPPORTED but FLAGS DIFFER between shells
+// bash: himBH (many extensions), sh/dash: h (minimal)
+//
+// PURIFICATION STRATEGY:
+// 1. Remove $- entirely (RECOMMENDED)
+// 2. Replace with explicit option checks
+// 3. Use set -e explicitly (don't check "e" in $-)
+//
+// PURIFICATION EXAMPLES:
+// BEFORE: echo "Shell options: $-"  ->  AFTER: (removed, not needed)

+//! declare -a items=(a b c)

+//!
+//! Classifies scripts into 5 safety categories using linter-based analysis:
+//! - **safe** (0): Passes all checks, properly quoted
+//! - **needs-quoting** (1): Unquoted variable expansions
+//! - **non-deterministic** (2): Contains $RANDOM, timestamps, wildcards without sort
+//! - **non-idempotent** (3): mkdir without -p, rm without -f, etc.
+//! - **unsafe** (4): Security violations (eval, command injection, running as root)
+//!
+//! Supports bash, Makefile, and Dockerfile formats (SSC-022).

+// - logic.rs: Hub that re-exports from focused submodules
+// - logic_lint.rs: Lint processing, filtering, and rule handling
+// - logic_dockerfile.rs: Dockerfile purification, analysis, build helpers
+// - logic_format.rs: Formatting, display, and report generation
+// - logic_shell.rs: Shell detection, normalization, file type detection
+// - logic_validate.rs: Validation, verification, and checking
+// - commands.rs: Thin I/O shim (reads files, calls logic, prints output)
+//
+// This separation enables:
+// - Unit testing of all business logic
+// - High test coverage (95%+ target)
+// - Clear separation of concerns

+//! # Corpus-Driven Transpilation Quality Module
+//!
+//! Implements the corpus registry, runner, and scoring system for measuring
+//! and improving transpilation quality across Bash, Makefile, and Dockerfile
+//! targets. Each corpus entry is a **potential falsifier** (Popper, 1959):
+//! an input-output pair that could demonstrate transpilation failure.
+//!
+//! ## Architecture
+//!
+//! - **Registry**: `CorpusEntry` and `CorpusRegistry` types for metadata management
+//! - **Runner**: `CorpusRunner` that transpiles entries and compares against expected output
+//! - **Scoring**: 100-point quality score (transpilation + correctness + coverage + lint + determinism)
+//! - **Convergence**: Tracks transpilation rate over iterations (Kaizen methodology)
+//!
+//! ## V2 Scoring Formula
+//!
+//! ```text
+//! Score = A(30) + B_L1(10) + B_L2(8) + B_L3(7) + C(15) + D(10) + E(10) + F(5) + G(5)
+//! ```
+//!
+//! Gates: A < 60% → B-G = 0; schema_invalid → score = 0; B_L1 fail → B_L2/B_L3 = 0

+//! Coverage tests for posix.rs — targeting uncovered branches
+//!
+//! Focuses on:
+//! - emit_shell_value branches (EnvVar, Arg, ArgWithDefault, ArgCount, ExitCode,
+//!   DynamicArrayAccess, LogicalAnd/Or/Not runtime, LogicalNot constant-fold)
+//! - emit_concatenation branches (Bool, EnvVar, Arg, ArgWithDefault, ArgCount,

+//! - emit_arithmetic_operand (DynamicArrayAccess, CommandSubst, unsupported)
+//! - emit_while_statement (LogicalAnd, LogicalOr, LogicalNot, general condition)
+//! - emit_test_expression (String "0", CommandSubst predicate vs non-predicate)
+//! - selective runtime emission (all rash_ functions)
+//! - separate_functions with non-Sequence IR
+//! - emit_function with empty body known command (no emit)
+//! - emit_function with params, no-params
+//! - Return with and without value
+//! - ForIn emission
+//! - empty Sequence noop path
+//! - Case arm with guard
+//! - classify helpers: classify_if_structure, classify_test_expression

 //! Intermediate Representation (IR) module
 //!
 //! ## Safety Note
-//! IR uses unwrap() on validated AST operations and checked invariants.
-#![allow(clippy::unwrap_used)]
-#![allow(clippy::indexing_slicing)]
-
+//! IR operations use fallible indexing with proper error handling.
+//! Production code MUST NOT use unwrap() (Cloudflare-class defect prevention).
+//!
+//! ## Module structure
+//! - `convert`: Core AST-to-IR entry point, shadow/loop helpers
+//! - `convert_stmt`: Top-level statement conversion (`convert_stmt`, `convert_stmts`)
+//! - `convert_fn`: Function-context statement conversion (`convert_stmt_in_function`)
+//! - `expr`: Expression-to-ShellValue conversion (operators, literals, index)
+//! - `expr_calls`: Function/method call expression converters
+//! - `pattern`: Match/pattern and range handling
+//! - `optimizations`: Constant folding, dead code elimination, IR transforms

+//! shell rules. This module identifies which 1-indexed line numbers fall inside
+//! such embedded programs so diagnostics on those lines can be suppressed.

+//! BASH004: Dangerous rm -rf Without Validation
+//!
+//! **Rule**: Detect `rm -rf` with variables that could expand to `/` or empty
+//!
+//! **Why this matters**:
+//! `rm -rf "$DIR"` where DIR is empty expands to `rm -rf ""` which can be
+//! catastrophic. `rm -rf $DIR/` where DIR is empty becomes `rm -rf /`.
+//! Always validate variables before destructive operations.
+//!
+//! ## Examples
+//!
+//! Bad:
+//! ```bash
+//! rm -rf "$DIR"
+//! rm -rf $BUILD_DIR/
+//! rm -rf "${INSTALL_PREFIX}"/lib
+//! ```
+//!
+//! Good:
+//! ```bash
+//! rm -rf "${DIR:?Variable not set}"
+//! [ -n "$BUILD_DIR" ] && rm -rf "$BUILD_DIR/"
+//! # Or use a safe default
+//! rm -rf "${INSTALL_PREFIX:-/usr/local}"/lib
+//! ```

+//! ```dockerfile
+//! ENTRYPOINT ["/bin/sh"]
+//! ENTRYPOINT ["/bin/bash"]
+//! ```
+//!
+//! ✅ **GOOD** (direct process):

+//! DOCKER008: Shell in CMD detection (F062) and shell form vs exec form (F072)
+//!
+//! **Rule**: Detect CMD directives that use shell interpreters
+//!
+//! **Why this matters**:
+//! Using `sh -c` in CMD adds an unnecessary shell layer, prevents proper
+//! signal handling, and makes the container harder to manage.
+//!
+//! ## Examples
+//!
+//! ❌ **BAD** (shell in CMD):
+//! ```dockerfile
+//! CMD ["sh", "-c", "python app.py"]
+//! CMD /bin/sh -c "python app.py"
+//! ```
+//!
+//! ✅ **GOOD** (direct execution):
+//! ```dockerfile
+//! CMD ["python", "app.py"]
+//! CMD python app.py
+//! ```

+//! DOCKER011: USER directive validation (F069)
+//!
+//! **Rule**: Validate USER directive for non-root execution
+//!
+//! **Why this matters**:
+//! Running containers as root is a security risk. Best practice is to
+//! run as a non-root user to limit potential damage from vulnerabilities.
+//!
+//! ## Examples
+//!
+//! ❌ **BAD** (running as root):
+//! ```dockerfile
+//! FROM python:3.12
+//! COPY app.py /
+//! USER root
+//! CMD ["python", "app.py"]
+//! ```
+//!
+//! ✅ **GOOD** (non-root user):
+//! ```dockerfile
+//! FROM python:3.12
+//! RUN useradd -r -u 1001 appuser
+//! COPY app.py /
+//! USER appuser
+//! CMD ["python", "app.py"]
+//! ```

+//! LAUNCHD001: macOS launchd plist validation (F076-F085)
+//!
+//! **Rule**: Validate launchd plist files for common issues
+//!
+//! **Why this matters**:
+//! Invalid launchd plist files can prevent daemons from starting on macOS.
+//! Proper validation ensures services run correctly on macOS systems.
+//!
+//! ## Checks implemented:
+//! - F076: Valid plist XML structure
+//! - F077: Correct Label (reverse-domain identifier)
+//! - F078: ProgramArguments array format
+//! - F079: RunAtLoad boolean
+//! - F080: KeepAlive configuration
+//! - F081: StandardOutPath validation
+//! - F082: StandardErrorPath validation
+//! - F083: EnvironmentVariables dictionary
+//! - F084: WorkingDirectory validation
+//! - F085: UserName validation

+//! PERF001: Useless use of cat (performance)
+//!
+//! **Rule**: Detect `cat file | cmd` where cmd can read from file directly
+//!
+//! **Why this matters**:
+//! Piping through `cat` spawns an unnecessary process and adds overhead.
+//! Most commands (grep, sed, awk, sort, wc) can read files directly.
+//!
+//! **Auto-fix**: Safe - suggest removing cat and passing file as argument
+//!
+//! ## Examples
+//!
+//! Bad (spawns extra process):
+//! ```bash
+//! cat file.txt | grep pattern
+//! ```
+//!
+//! Good (direct file argument):
+//! ```bash
+//! grep pattern file.txt
+//! ```

+//! PERF002: Command substitution inside loop body
+//!
+//! **Rule**: Detect `$(...)` inside for/while loop bodies
+//!
+//! **Why this matters**:
+//! Command substitution in a loop forks a subshell on every iteration,
+//! causing significant performance degradation for large iteration counts.
+//! Moving the substitution outside the loop can dramatically improve performance.
+//!
+//! **Auto-fix**: None (manual refactoring required)
+//!
+//! ## Examples
+//!
+//! Bad (forks subshell each iteration):
+//! ```bash
+//! for i in $(seq 1 100); do
+//!     owner=$(stat -c '%U' "$i")
+//!     echo "$owner"
+//! done
+//! ```
+//!
+//! Good (compute once outside loop):

+//! REL004: TOCTOU lock file race condition
+//!
+//! **Rule**: Detect `if [ ! -f lockfile ]; then touch lockfile` pattern
+//!
+//! **Why this matters**:
+//! The pattern `if [ ! -f file ]; then touch file; fi` has a Time-of-Check
+//! to Time-of-Use (TOCTOU) race condition. Between the check and the touch,
+//! another process may create the file. Use atomic operations like `mkdir`
+//! or `ln` for lock files instead.
+//!
+//! **Auto-fix**: None (requires architectural change)
+//!
+//! ## Examples
+//!
+//! Bad (TOCTOU race):
+//! ```bash
+//! if [ ! -f /tmp/lock ]; then
+//!     touch /tmp/lock
+//! fi
+//! ```
+//!
+//! Good (atomic lock):
+//! ```bash
+//! mkdir /tmp/lock.d 2>/dev/null || { echo "locked"; exit 1; }

-// SC2064: Use single quotes, otherwise this expands now rather than when signalled
-//
-// When using trap with double quotes, variables are expanded immediately when the
-// trap is set, not when the signal is received. This usually causes bugs because
-// the trap uses stale values or empty variables.
-//
-// Examples:
-// Bad:
-//   trap "rm $tmpfile" EXIT          // $tmpfile expands NOW (might be empty)
-//   tmpfile="/tmp/data"
-//   trap "echo $status" INT          // $status expands when trap is set
-//
-// Good:
-//   trap 'rm "$tmpfile"' EXIT        // $tmpfile expands WHEN trap fires
-//   tmpfile="/tmp/data"              // Value available when trap executes
-//   trap 'echo "$status"' INT        // $status expands at signal time
-//
-// Why this matters:
-//   - Variables might not be set yet when trap is defined
-//   - Variables might change before signal is received
-//   - Trap should use current values, not definition-time values
-//   - Common source of "file not found" errors in cleanup traps
-//
-// Exception: If you specifically want early expansion, use double quotes intentionally.

+//! SEC013: Insecure Temporary File Creation
+//!
+//! **Rule**: Detect insecure temporary file creation patterns
+//!
+//! **Why this matters**:
+//! Using predictable temporary file paths (e.g., /tmp/myfile) creates race conditions
+//! (TOCTOU) and symlink attacks. An attacker can create a symlink at the predicted path
+//! to overwrite arbitrary files.
+//!
+//! **Auto-fix**: Replace with mktemp
+//!
+//! ## Examples
+//!
+//! Bad:
+//! ```bash
+//! echo data > /tmp/myapp.log
+//! TMPFILE=/tmp/output.$$
+//! cat foo > /tmp/bar
+//! ```
+//!
+//! Good:
+//! ```bash
+//! TMPFILE=$(mktemp)
+//! echo data > "$TMPFILE"
+//! TMPDIR=$(mktemp -d)
+//! ```

+//! **Why this matters**:
+//! Using unsanitized user input in file paths allows attackers to access files
+//! outside intended directories via `../` sequences.
+//!
+//! ## Examples
+//!
+//! Bad:
+//! ```bash
+//! cat "/data/$USER_INPUT"
+//! rm -rf "/uploads/$FILENAME"
+//! source "$CONFIG_DIR/$MODULE"
+//! ```
+//!
+//! Good:
+//! ```bash
+//! # Validate input doesn't contain path traversal
+//! case "$USER_INPUT" in
+//!   *..* ) echo "Invalid path"; exit 1 ;;
+//! esac
+//! realpath --relative-to=/data "/data/$USER_INPUT"

+//! SYSTEMD001: systemd unit file validation (F086-F095)
+//!
+//! **Rule**: Validate systemd service unit files for common issues
+//!
+//! **Why this matters**:
+//! Invalid systemd unit files can cause services to fail to start,
+//! restart improperly, or have security issues.
+//!
+//! ## Checks implemented:
+//! - F086: Valid unit file structure
+//! - F087: Correct Type= directive
+//! - F088: Valid ExecStart= path
+//! - F089: Valid ExecReload= configuration
+//! - F090: Appropriate Restart= policy
+//! - F091: Reasonable RestartSec= value
+//! - F092: LimitMEMLOCK for mlock services
+//! - F093: After=/Requires= dependency validation
+//! - F094: WantedBy= target validation
+//! - F095: EnvironmentFile= path validation

+//! Extended coverage tests for `validate_expr_in_exec_context` and related paths.
+//!
+//! Focuses on exercising branches not yet covered:
+//! - Nested expression types in exec context (MethodCall with args, deeply nested)
+//! - Range with shellshock in start/end
+//! - Block with complex inner statements
+//! - FunctionCall inside exec context that itself recurses to normal validate_expr
+//! - Literal variants (Bool, U16, U32, I32) in exec context
+//! - validate_literal_in_exec_context for each Literal variant
