Changed: Refactors Gram determinant calculation with LDLT#167acgetchell merged 6 commits intomainfrom
Conversation
Refactors the Gram determinant calculation to use LDLT factorization from the `la-stack` crate for improved efficiency and numerical stability by exploiting symmetry. Also, updates the `la-stack` dependency version.
WalkthroughAdds LDLT-based Gram determinant computation, tightens cavity-boundary extraction with ridge incidence/connectivity checks and new ConflictError variants, temporarily hardens validation during insertion, renames SimplexCounts→FVector across topology APIs, updates tests/examples/tooling, and bumps la-stack dependency.

527-557: spell-check rename handling is incorrect withgit status --porcelain -zWith
--porcelain -z, Git does not emit the"oldname -> newname"textual form; instead, renames are reported as two NUL-separated paths. In this loop:while IFS= read -r -d '' status_line; do if [[ "$status_line" =~ ^..[[:space:]](.*)$ ]]; then filename="${BASH_REMATCH[1]}" if [[ "$filename" == *" -> "* ]]; then filename="${filename#* -> }" fi files+=("$filename") fi done < <(git status --porcelain -z --ignored=no)rename entries will only contribute the old path (and the
*" -> "*branch is never hit), so:
- cspell may be invoked on paths that no longer exist after a
git mv, and- the renamed-to path is never spell-checked.
It would be better to either:
- switch to a NUL-safe command that directly lists changed file paths (e.g.,
git diff --name-only -zplusgit ls-files --othersfor untracked), or- explicitly handle the two-path rename format in
--porcelain -zand always enqueue the final/new path.As-is, this is a functional bug for rename workflows.

17-21: Tooling, setup, and lint/fix workflow refactor is coherent and extensibleThis is a substantial but well-structured upgrade of the developer workflow:
_ensure-*helpers foractionlint, Prettier/npx,shfmt,taplo,uv,yamllintare consistent and provide clear remediation messages.fixnow composestoml-fmt, Rustfmt, Python fixes, shell formatting, markdown-fix, and yaml-fix into a single “apply auto-fixes” entrypoint, which matches the help text.markdown-fixandmarkdown-lintwrapmarkdownlint(via npx) in a way that scales to many files and keeps config centralized.python-check/python-lint/python-typecheckgive a clear separation of format, lint, and type checks underuv, andlint-codenow routes through them.shell-checkvsshell-fmtcleanly split validation from mutation with appropriateshfmtandshellcheckusage.setupdelegating tosetup-toolsand then runninguv sync --group devpluscargo buildmakes onboarding much smoother.validate-jsonviajq emptyand the YAMLyaml-fix/yaml-lintpair round out config validation nicely.test-integrationusingcargo test --tests --verbosebetter matches the description (“all integration tests”).Two minor refinements to consider:
- On non-macOS systems without Homebrew,
setup-toolscurrently exits early once it discoversbrewis missing, without running the later “Verifying required commands are available…” section. If a Linux developer has already installeduv,jq, etc. by other means, it would be useful to still run the verification loop instead of hard-failing oncebrewis absent.- For
yaml-fix, you’re already guarding Prettier vs npx carefully; if you ever add more Prettier-based formatters, consider centralizing that logic into a shared helper to avoid subtle drift.Overall, the structure and messaging look solid.
Because this wiring depends on external tools (
uv,ruff,mypy,prettier,yamllint,jq, etc.), please:
- Verify
just setup-toolsbehaves sensibly on at least one non-Homebrew Linux environment (e.g., tools preinstalled via distro packages).- Run

71-71: Allowing LDLT identifiers in spell-check config is appropriateAdding
LDLT/ldltkeeps cspell from flagging the new linear-algebra API and tests; this is consistent with how other technical acronyms are handled here.
Based on learnings, this matches the existing approach of whitelisting domain-specific terms in cspell.json.Also applies to: 254-254

13-25: LDLT-based Gram determinant integration and clamping look consistentThe new
gram_determinant_ldlthelper and imports cleanly centralize LDLT usage:
ldlt(DEFAULT_SINGULAR_TOL)→det()/0.0(singular) /NaN(non-finite), withclamp_gram_determinantconverting those into clearCircumcenterErrors.- simplex and facet Gram-based volume paths now share this helper, keeping determinant handling symmetric and PSD-aware.
- Updated clamp docs correctly describe the “non-finite or (near-)negative ⇒ error; zero ⇒ degenerate simplex error” behavior, which matches the implementation.
- Tests (
gram_det_from_edges,test_gram_determinant_ldlt_known_spd, and the existing Gram-matrix volume tests) exercise the new path appropriately.I don’t see correctness or stability regressions in these changes.
Given the reliance on la-stack’s LDLT implementation and
DEFAULT_SINGULAR_TOL, please confirm that:
- Near-singular but valid Gram matrices in
test_gram_matrix_debugstill succeed instead of being classified as singular.- The new SPD test passes across your supported platforms and toolchains.

464-473: Verifycargo-tarpaulinbinary detection.The check
have cargo-tarpaulinlooks for a binary namedcargo-tarpaulinon PATH. Cargo subcommands installed viacargo installtypically create binaries with the crate name (e.g.,cargo-tarpaulin), so this should work. However, the later verification loop (line 478) doesn't includecargo-tarpaulinin the checked commands, creating an inconsistency.Consider either adding
cargo-tarpaulinto the verification loop for Linux systems, or documenting that coverage commands require manual verification.
519-533: Minor: Consider batching shfmt invocations.

655-667: LGTM!Correct use of

167-176: LGTM!The triple clippy run (no-default-features, default, all-features) is intentional and necessary to catch warnings in feature-gated code paths. Based on learnings, this covers the

itional,retriable, andretryableare preserved as expected.tests/delaunay_edge_cases.rs (1)
107-192: 4D Euler-regression test is well targetedThe new 4D regression test exercises construction, basic size bounds, and full Level 1–3 validation on the previously failing configuration, which is exactly what you want to guard against the χ=0 shell regression. No issues spotted.
src/core/triangulation.rs (7)
31-37: Level‑3 topology docs correctly reflect new boundary checksThe updated Level‑3 documentation (codimension‑1 manifoldness and codimension‑2 closed boundary) matches the implemented validation steps and clarifies the invariants enforced by
is_valid().
104-106: New imports are appropriate for boundary and adjacency validationAdding
VertexKeyBuffer,VertexToCellsMap, fast hash helpers, andAllFacetsIter/BoundaryFacetsIter/FacetHandle/facet_key_from_verticesis consistent with the new boundary-closure and adjacency APIs. No issues with visibility or coupling here.Also applies to: 108-113
246-258: BoundaryRidgeMultiplicity error type is well-structuredThe new
TriangulationValidationError::BoundaryRidgeMultiplicitycleanly encapsulates codimension‑2 boundary failures with a canonical ridge key and multiplicity count, giving useful diagnostics without exposing internal data structures.
1458-1476: is_valid() integration of closed-boundary check is soundPlumbing
validate_closed_boundary_with_mapimmediately after manifold facet validation ensures codimension‑2 boundary issues are caught early, before global connectedness and Euler checks. The reuse of a singlefacet_to_cellsmap keeps the cost reasonable and matches the documented Level‑3 guarantees.Also applies to: 1501-1529
1745-1843: Closed-boundary validator correctly enforces “no boundary of boundary”
validate_closed_boundary_with_map:
- Skips irrelevant cases (D<2, no boundary facets).
- Derives each boundary facet’s vertex set from the owning cell and facet_index with robust consistency checks.
- Enumerates all boundary ridges and requires each to have incidence 2, flagging any 1- or >2‑incidence ridge as
BoundaryRidgeMultiplicity.The logic is dimension-agnostic, doesn’t rely on neighbor pointers, and aligns with the new tests, so manifold-with-boundary semantics are enforced as intended.
2371-2382: Debug logging now only fires for genuinely suspicious operationsConditioning
log_validation_trigger_if_enabledon bothshould_validate()andsuspicion.is_suspicious()avoids debug-log spam for Always/DebugOnly policies while still logging when a suspicious insertion actually triggers Level‑3 validation. Behavior of validation itself is unchanged.
3778-3897: New closed-boundary tests cover core OK and error pathsThe added tests:
- Validate the happy path for a single tetrahedron.
- Confirm the 2D closed surface (tetra boundary as S²) is a no-op for boundary-closure checks.
- Construct a 3D configuration with an edge shared by four boundary facets and verify both the direct
validate_closed_boundary_with_maperror and thatis_valid()surfacesBoundaryRidgeMultiplicitybefore connectedness.This gives good coverage of the new codimension‑2 invariant.
src/core/algorithms/locate.rs (5)
79-126: ConflictError extensions capture new boundary-degeneracy modesAdding
DisconnectedBoundaryandOpenBoundary(plus the existingRidgeFan) provides clear, structured error cases for non-ball cavity boundaries and open boundary surfaces during conflict extraction. The messages strongly indicate “retryable degeneracy” semantics, which fits with the perturbation-based insertion strategy.Please ensure wherever
ConflictErroris wrapped intoInsertionError(e.g., inInsertionError::is_retryableor similar helpers) these new variants are treated consistently with other degeneracy cases so that they participate correctly in the perturbation retry path, not as hard structural failures.Also applies to: 127-156
158-165: RidgeInfo is a minimal, effective container for ridge incidence
RidgeInfocompactly records per-ridge vertex count, facet incidence count, and up to two incident boundary facets. This is exactly what’s needed to both detect fans/open ridges and build a boundary-facet adjacency graph without extra passes.
616-625: Facet-incidence–based cavity boundary classification is robustThe reworked
extract_cavity_boundary:
- Avoids relying on neighbor pointers (which may be inconsistent during local updates), instead computing boundary facets purely from facet incidence within
conflict_cells.- Uses a conflict-set hash set and a facet-hash →
FacetHandlemap to determine which facets are internal vs. on the cavity boundary.- Caches canonical facet vertex sets for later ridge analysis, avoiding redundant cell vertex lookups.
This is a solid foundation for the new topology checks and makes boundary extraction more resilient to transient TDS states.
Also applies to: 631-690
694-767: Ridge counting for boundary facets correctly detects non-manifold ridgesThe ridge enumeration code:
- Derives ridges (D‑2 simplices) by omitting each facet vertex in turn.
- Hashes each ridge via the sorted vertex keys and accumulates
facet_countplus association back to the boundary-facet indices.- Leaves internal facets untouched, focusing solely on the cavity boundary.
This aligns with the global BoundaryRidgeMultiplicity logic and prepares the adjacency graph for connectivity checks.
768-838: Boundary adjacency and connectivity checks match intended topology invariantThe final phase of
extract_cavity_boundary:
- Rejects ridges with
facet_count == 1asOpenBoundaryandfacet_count >= 3asRidgeFan.- Builds a symmetric adjacency list between boundary facets for all ridges with exactly two incident facets.
- Performs a simple DFS to assert that all boundary facets lie in one connected component, otherwise returning
DisconnectedBoundary.This ensures the cavity boundary is a single closed manifold component before insertion proceeds, which directly addresses the previous shell/Euler issues. Implementation is straightforward and dimension-independent.
src/core/algorithms/incremental_insertion.rs (1)
241-250: LGTM! Logical extension of retry logic for boundary topology issues.The addition of
DisconnectedBoundaryandOpenBoundaryto the retryable conflict errors is consistent with the existing pattern—these represent topological degeneracies (disconnected cavity boundaries, unclosed boundaries) that may be resolved via coordinate perturbation, similar to howNonManifoldFacetandRidgeFanare handled. The updated comment accurately reflects the expanded scope.docs/validation.md (3)
42-48: Excellent clarification of automatic Level 3 validation scope.The expanded enumeration makes it immediately clear what checks are included in automatic validation (codimension-1/2 manifoldness, connectedness, isolated vertices, Euler characteristic) versus what is excluded (Level 4 Delaunay property). This helps users understand exactly what
ValidationPolicycontrols.
251-265: Outstanding breakdown of Level 3 validation checks.The numbered list with detailed explanations for each check (facet degree, boundary neighbor consistency, closed boundary, connectedness, isolated vertices, Euler characteristic) significantly improves the documentation. The distinction between codimension-1 and codimension-2 manifoldness is mathematically precise, and the explanatory notes (e.g., "no boundary of boundary," "interior ridges can have higher degree") provide helpful context without overwhelming the reader.
482-487: Troubleshooting section properly updated to match new validation checks.The expanded problem description now covers boundary closure issues, boundary ridge degree requirements, and isolated vertices, which aligns with the enhanced Level 3 checks described earlier in the document. This ensures users encountering these new validation failures will have guidance on how to address them.
Renames the `SimplexCounts` struct to `FVector` to better reflect its mathematical meaning as the f-vector in topology, representing the counts of simplices of different dimensions. This change improves code readability and aligns the naming convention with standard topological terminology. (Internal refactoring, no API change.)

403-509: Consider splitting setup-tools for better maintainability.The
setup-toolsrecipe is comprehensive and functional, providing excellent developer experience with OS detection, Homebrew integration, and clear error messages. However, at ~106 lines, it's quite long and handles multiple concerns (package manager detection, tool installation, verification).Consider optionally refactoring into smaller helper recipes for easier maintenance, though this works well as-is.
543-586: Good handling of git status edge cases.The spell-check recipe now properly handles renames, copies, and deletions when parsing
git status --porcelain -z. The logic is correct, and the existing comments help explain the approach.One optional improvement: The comment could more explicitly show the git status format for renames (
R old_path\0new_path\0) to make the two-token read pattern clearer.src/topology/characteristics/euler.rs (1)
281-321: Consider documenting the combination generation algorithm.The implementation is correct and uses the standard lexicographic combination generation algorithm. However, the pivot-based logic (lines 305-320) is subtle and may not be immediately clear to maintainers.
Optional: Add explanatory comment
Consider adding a brief comment explaining the algorithm, such as:
fn insert_simplices_of_size( vertex_keys: &[VertexKey], simplex_size: usize, simplex_set: &mut FastHashSet<SmallBuffer<VertexKey, MAX_PRACTICAL_DIMENSION_SIZE>>, ) { let n = vertex_keys.len(); if n < simplex_size { return; } - // Generate all C(n, simplex_size) combinations of vertex keys using indices. + // Generate all C(n, simplex_size) combinations using the standard lexicographic algorithm. + // We maintain indices[0..simplex_size] representing positions in vertex_keys. + // To get the next combination, find the rightmost index that can be incremented, + // increment it, and reset all subsequent indices to consecutive values. let mut indices: SmallBuffer<usize, MAX_PRACTICAL_DIMENSION_SIZE> = (0..simplex_size).collect();

290-305: LGTM! Clean markdown formatting integration.The markdown-fix recipe properly handles file enumeration and provides clear feedback. The use of
git ls-filesensures only tracked files are formatted.
372-386: LGTM! Well-structured Python quality checks.The Python recipes follow the established pattern:
python-checkfor non-mutating validation (ruff + type checking)python-fixfor auto-fixes- Clear separation of concerns
510-541: LGTM! Comprehensive shell script quality checks.The shell script recipes properly combine shellcheck (linting) and shfmt (formatting) with appropriate guards for tool availability and empty file lists. The note about justfiles is helpful.
604-607: LGTM! Clear test organization.The new
test-integrationrecipe provides explicit separation between fast unit/doc tests and slower integration tests, improving CI efficiency and developer workflow.
661-673: LGTM! Simple and effective JSON validation.Using
jq emptyis a clean approach to validate JSON syntax. The recipe follows the established pattern for file enumeration and error handling.
688-733: LGTM! Robust YAML formatting and linting.The YAML recipes handle multiple tool scenarios gracefully:
yaml-fixintelligently detects prettier/npx availability and the--yesflag supportyaml-lintuses yamllint with strict checking- The comment explaining the CLI-flag-only approach (line 715) is helpful
The defensive programming for npx version differences is good practice.
187-193: LGTM! Proper use of centralized coverage configuration.Both coverage recipes correctly use the
_coverage_base_argsvariable with appropriate output formats (HTML for local development, XML for CI).

justfile (2)
402-511: Well-structured tooling setup with good OS awareness.The
setup-toolsrecipe is comprehensive and properly handles platform differences. The verification step (lines 479-508) ensures all required tools are available before proceeding.Minor optional suggestion: Consider extracting the Homebrew installation logic (lines 417-425) into a separate function if you plan to add more package managers in the future.
546-592: Complex but correct git status parsing for spell-check.The refactored spell-check recipe properly handles git renames and copies (lines 567-571). The logic correctly reads two NUL-delimited tokens for renamed/copied files and uses the destination path.
The fallback from
cspelltonpx(lines 581-589) provides good flexibility.Optional: Consider adding a comment explaining the R/C status handling
The git status rename/copy parsing is subtle. Consider adding a brief inline comment for future maintainers:
# For renames/copies, consume the destination path (the next NUL-delimited token). + # Git emits: "R old_path\0new_path\0" for renames if [[ "$status" == *"R"* || "$status" == *"C"* ]]; thensrc/topology/characteristics/euler.rs (2)
281-328: Lexicographic combination generation is correct.The algorithm correctly generates all C(n, simplex_size) combinations using the standard lexicographic approach. The pivot-finding logic (lines 313-321) properly identifies the rightmost position that can be incremented and handles loop termination when all combinations are exhausted.
Optional: Consider pre-sorting vertex_keys to eliminate per-combination sorting
If
vertex_keyswere provided in sorted order (or sorted once at the start ofinsert_simplices_of_size), line 307's per-combination sort could be eliminated. The lexicographic generation would then naturally produce combinations in canonical order. This micro-optimization may be beneficial if profiling shows sorting overhead in high-dimensional cases.fn insert_simplices_of_size( vertex_keys: &[VertexKey], simplex_size: usize, simplex_set: &mut FastHashSet<SmallBuffer<VertexKey, MAX_PRACTICAL_DIMENSION_SIZE>>, ) { let n = vertex_keys.len(); if n < simplex_size { return; } + + // Sort once to ensure canonical order + let mut sorted_keys: SmallBuffer<VertexKey, MAX_PRACTICAL_DIMENSION_SIZE> = + vertex_keys.iter().copied().collect(); + sorted_keys.sort(); - let mut indices: SmallBuffer<usize, MAX_PRACTICAL_DIMENSION_SIZE> = (0..simplex_size).collect(); + let mut indices: SmallBuffer<usize, MAX_PRACTICAL_DIMENSION_SIZE> = + (0..simplex_size).collect(); 'outer: loop { let mut simplex_vertices: SmallBuffer<VertexKey, MAX_PRACTICAL_DIMENSION_SIZE> = SmallBuffer::new(); for &vertex_index in &indices { - simplex_vertices.push(vertex_keys[vertex_index]); + simplex_vertices.push(sorted_keys[vertex_index]); } - simplex_vertices.sort(); simplex_set.insert(simplex_vertices); // ... rest unchanged
606-659: Tests updated consistently for FVector.All unit tests have been properly updated to use
FVector. The existing test coverage validates the correctness of the type rename and the counting functionality through integration tests.Consider adding a focused unit test for
insert_simplices_of_sizeto explicitly verify the lexicographic combination generation with various edge cases (e.g., simplex_size == n, simplex_size == 1, small n values). While the function is tested indirectly throughcount_simplices, a dedicated test would make the expected behavior more explicit and aid future maintenance.Example test structure:
#[test] fn test_insert_simplices_of_size() { use crate::core::triangulation_data_structure::VertexKey; let mut set = FastHashSet::default(); // Test case: C(3, 2) = 3 combinations let keys: Vec<VertexKey> = vec![/* ... */]; insert_simplices_of_size(&keys, 2, &mut set); assert_eq!(set.len(), 3); // Verify specific combinations exist // ... }

Speeds up simplex generation within Euler characteristic calculation by pre-sorting vertex keys for cells and facets. This eliminates per-combination sorting during simplex insertion, as combinations are generated in sorted order from sorted input. Adds a test case for `insert_simplices_of_size`.

324-333: Consider clarifying the pivot-finding logic.The combination generation algorithm is correct, but the pivot-finding control flow at lines 324-333 is slightly confusing with the nested condition checking
pivot == 0inside the while loop. The logic works correctly (when all indices are maxed out, we exit), but it requires careful reading to verify.♻️ Optional refactor for clarity
Consider restructuring for more explicit intent:
- let mut pivot = simplex_size; - while pivot > 0 { - pivot -= 1; - if indices[pivot] != pivot + n - simplex_size { - break; - } - if pivot == 0 { - break 'outer; - } - } + // Find the rightmost index that can be incremented + let mut pivot = simplex_size; + loop { + if pivot == 0 { + break 'outer; // All indices at maximum values + } + pivot -= 1; + if indices[pivot] < pivot + n - simplex_size { + break; // Found index that can be incremented + } + }This makes the termination condition more explicit: we check for completion before attempting to find a pivot, making the loop invariant clearer.

43-64: LGTM! API rename improves clarity.The rename from
SimplexCountstoFVectoraligns with standard topology literature terminology. The documentation clearly explains the f-vector concept with good examples.
251-283: Excellent performance optimization!The refactoring to use a single pass over cells with per-dimension sets is a significant improvement over the previous approach that would enumerate all cells once per intermediate dimension. Pre-sorting vertex keys once per cell eliminates redundant per-combination sorting.

9-15: LGTM! Good DRY refactoring.Extracting the common tarpaulin arguments into a reusable variable improves maintainability and ensures consistent coverage settings across recipes. The inline documentation of the timeout setting is helpful.
33-43: LGTM! Flexible verification helper.The fallback logic (prettier → npx → error) provides good flexibility while maintaining clear requirements. Error messages guide users to the recommended installation method.
406-512: Comprehensive tooling setup with good platform awareness.The
setup-toolsrecipe provides thorough cross-platform tooling installation. The size (~100 lines) is acknowledged in the comments (line 404) as something that may be split later if it grows further. The conditional handling of cargo-tarpaulin (Linux-only) and brew availability is well-structured.
551-593: LGTM! Robust handling of git status edge cases.The updated spell-check recipe properly handles file renames/copies in git status output (lines 568-572) and uses NUL-delimited output for filenames with spaces. The detailed comments explaining the git status format make the parsing logic clear.
695-726: LGTM! Well-structured YAML formatting with good CI support.The recipe properly detects and uses the
--yesflag for npx in CI environments (lines 712-715). The comment at line 722 explains the rationale for using CLI flags over a config file, keeping the scope limited to YAML files only.
1-740: Well-organized expansion of development workflows.The justfile has grown significantly but maintains clear organization with consistent patterns across similar recipe groups (shell-, markdown-, yaml-*). The separation between mutating (fix/fmt) and non-mutating (check/lint) operations is consistent throughout. The updated help text (lines 216-263) effectively guides users through the expanded capabilities.
Updates the serde_json dependency from v1.0.148 to v1.0.149. Also, fixes a bug in the `insert_simplices_of_size` function in `euler.rs`, where the loop condition was incorrect, causing potential issues when generating combinations. Adds tests for classifying a closed 2D surface (sphere) and counting boundary simplices to verify correct topological classification and boundary detection.
