Closes #638.

The defect

SimulationDataSeeder.SeedAsync called DailyEntryLockSweep.RunAsync once. That sweep is built for the DurableJobWorker poll: it takes .Take(BatchSize) with BatchSize = 200 per account, locks that batch and returns, and the poll 30s later takes the next one. A run-then-exit seed verb has no poll behind it.

ExpectedLockedEntryCount mirrors the sweep's cutoff rule, so it expects every eligible entry locked. The two agree only while FlockTopologyCount(2) × (HistoryDays − LockAfterDays(7)) ≤ 200 — i.e. HistoryDays ≤ 107. Above that the completion check could not be satisfied on any database, however clean, and the failure is post-commit: rows written, no manifest, exit 1.

The fix

• DailyEntryLockSweep.RunAsync now returns how many entries the pass actually locked, and documents the drain contract. BatchSize becomes public because the caller derives its bound from it.
• SimulationDataSeeder.DrainLockSweepAsync re-invokes until a pass reports no progress, under a bound derived from the fixture's own size.
• BatchSize stays 200, per the issue: it is sized for the serving-path worker, and raising it moves the ceiling rather than removing it.

The terminator is the locked count, not the due count. A batch that came back due but locked nothing — every Lock() failed, or a concurrent adjust won every Version race — has made no progress. Treating it as progress would spin forever; reporting zero stops the drain and lets the completion check fail loudly, which is the correct outcome for a genuinely stuck batch. The per-account catch contributes 0 for the same reason.

await lockSweep.RunAsync(ct) in DurableJobWorker and in DailyEntryAdjustTests is source-compatible with the Task<int> return; no caller changed.

The test

SimulationDeepSeedDrainTests seeds its own container at HistoryDays=112 and asserts two separate things:

1. the seed validates (the guarantee);
2. more than one BatchSize worth of entries ended up Locked, read back off the database (the reason — so the class cannot pass on a fixture too shallow to prove anything), plus nothing eligible left Submitted.

Depth 112, not the issue's 120 or the true minimum 108: 108 can land on exactly 200 eligible depending on how farm-local "today" skews against the UTC seed anchor, which would make the class pass vacuously. 112 yields 208–210 either way. It costs ~12s wall clock including container start.

Verification

• Full suite green at dotnet test Cluckwork.sln: 365 + 10 + 234 + 1645 = 2254 passed, 0 failed.
• Mutation check (green baseline first, then the mutant, then restore-and-rebuild before re-running):
  • baseline with the fix — both new tests pass;
  • mutant await DrainLockSweepAsync(sim, ct); → await lockSweep.RunAsync(ct); — both fail, on their own named assertions, with the exact symptom the issue reports:

    Deep simulation seed failed (Failed): … dailyEntries.submitted: expected 12, got 20; dailyEntries.locked: expected 208, got 200
    Expected more than one sweep pass worth of locked entries (> 200) at HistoryDays=112, got 200.
    

  • fix restored, rebuilt, re-run — green.

Docs

docs/runbooks/simulation-fixture-on-a-dev-database.md loses the ceiling box, the depth-ramping loop, the overshoot-recovery paragraph and the pass-count arithmetic; the "If it fails" row now reads the symptom as a drain regression rather than an expected limit; drill steps 5–6 collapse into one deep-seed step that would have gone red before this change. What replaces the ceiling is the honest remaining constraint: depth costs time, because the history loop is O(HistoryDays × flocks) real round-trips.

The class-header "depth-robust by construction" claim is annotated rather than widened — it was true of the expectations and false of the seeding, and #638 is exactly that gap.

Merge note

Touches the same runbook as #643 (k6 preparation steps), in different sections. Whichever lands second may need a trivial conflict resolution near the ## Drill heading.

Summary by CodeRabbit

• New Features

  • Simulation data seeding now supports unrestricted history depth and automatically processes all required lock-sweep batches in a single run.
  • Seeding reports the total number of entries locked and continues processing other accounts when an individual account encounters an error.

• Bug Fixes

  • Prevented partial simulation results by ensuring all eligible due entries are locked, including scenarios requiring multiple batches.

• Documentation

  • Updated simulation runbooks with current depth limits, cleanup guidance, failure behavior, and validation steps.

📝 Walkthrough

Walkthrough

The lock sweep now reports per-pass progress. The simulation seeder drains repeated passes with a calculated safeguard. Documentation removes the depth ceiling, and integration tests validate deep-history seeding and complete locking.

Changes

Simulation seed drain

Layer / File(s)	Summary
Lock sweep progress reporting src/Cluckwork.Infrastructure/Jobs/DailyEntryLockSweep.cs	RunAsync returns the number of entries locked in each pass. Account failures contribute zero and do not stop later accounts.
Seeder lock-sweep draining src/Cluckwork.Infrastructure/Persistence/SimulationDataSeeder.cs, docs/runbooks/simulation-fixture-on-a-dev-database.md	The seeder repeats lock-sweep passes until no progress occurs, with a maximum-pass safeguard. The runbook documents unrestricted depth and successful deep runs.
Deep-seed integration validation tests/Cluckwork.Api.IntegrationTests/SimulationDeepSeedDrainTests.cs	A 112-day simulation fixture verifies successful seeding, multiple batches, and no due submitted entries left unlocked.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to e49dc

The simulation seeding fix is mergeable with documentation follow-up: stale runbook references could mislead developers about supported fixture depth and omit the new deep-seed validation step.

CodeQL

The first run reported "3 new alerts including 3 high severity security vulnerabilities" — cs/cleartext-storage-of-sensitive-information at DailyEntryLockSweep.cs:76,125,128. None of them is new. They are alerts #1, #2 and #114, already open on main at lines 55, 102 and 105 of the same file; the statements are byte-identical to origin/main and this branch adds 23 lines above them, so CodeQL's diff attribution re-reported them against this PR.

All three flag the same thing: AccountId — a tenant Guid carried in the JWT account_id claim — appearing in a log message. That is not a credential, a secret or PII; it is the tenant correlator, and a background sweep has no request scope to carry it implicitly. CodeQL matches on its sensitive-name heuristic for "account".

Dismissed as false positives on the owner's instruction, together with the two siblings the same rule had open elsewhere:

Alert	Location	Reason
#1, #2	DailyEntryLockSweep.cs	false positive — tenant Guid, not a credential
#114	DailyEntryLockSweep.cs	false positive — same
#113	TenantResolutionMiddleware.cs	false positive — same
#116, #117	LogRedactionTests.cs	used in tests — the test logs a Guid.NewGuid() fake password to prove redaction strips it; the next line asserts DoesNotContain(password, rendered)

The CodeQL check on this PR now passes. Two unrelated medium alerts stay open on main and were not touched: #123 (js/file-access-to-http) and #118 (cs/exposure-of-sensitive-information).
