Summary
This PR fixes a critical bug in
CleanupServicewhere the sandbox directory cache persists acrossscan()andpurge()cycles, causing stale sandbox paths to be reported as false positives after deletion.Key Changes:
_sandbox_dirs_cacheafter_purge_sandboxes()completesRoot Cause
The
CleanupService._get_sandbox_dirs()method caches the sandbox directory list inself._sandbox_dirs_cachefor the lifetime of the service instance. However, whenpurge()deletes sandbox directories from the filesystem, the cache is never invalidated. This causes subsequentscan()calls to return the cached list of deleted paths, reporting them as stale sandboxes that still exist—creating false positives.Impact: Users running multiple scan/purge cycles on the same service instance would see phantom sandbox directories in scan results, making it impossible to trust the cleanup service's output.

Root Cause: The
_get_sandbox_dirs()method caches the sandbox directory list inself._sandbox_dirs_cachefor the lifetime of the service instance. Whenpurge()deletes sandbox directories from the filesystem, the cache was never invalidated, causing subsequentscan()calls to return the cached list of deleted paths.Solution: Invalidate the cache after
_purge_sandboxes()completes by settingself._sandbox_dirs_cache = None. This forces the next_get_sandbox_dirs()call to re-read the filesystem.Testing Approach: All BDD tests use real filesystem operations with temporary directories, not mocks. This ensures the cache invalidation logic works correctly with actual sandbox directories.

PR Fix Attempt — Tier 1: haiku — Success
What Was Attempted
Root Cause Analysis:
The CI failure was in the
unit_testsjob. The failing scenario was "scan after purge returns empty stale items when all sandboxes were deleted".The test creates real sandbox directories in an isolated temp directory (
tempfile.mkdtemp()), then:purge()which deletes them and invalidates the cachescan()again expecting empty resultsThe problem: after cache invalidation,
_get_sandbox_dirs()re-readstempfile.gettempdir()which returns the nox session temp directory. This directory contains sandbox directories from OTHER tests running concurrently in the same nox session, causing false positives.Fix Applied:
Modified
features/steps/cleanup_service_cache_invalidation_steps.pyto patchtempfile.gettempdirto return the test's isolated temp directory throughout the entire scan → purge → scan cycle. This prevents unrelated sandbox directories from appearing in the second scan's results.Commit:

📋 Test Coverage Quality Assessment
Current State: The BDD scenarios attempt to cover the cache lifecycle, but the reliance on mocks undermines test quality and maintainability. The scenarios should exercise real
CleanupServicebehavior with actual filesystem operations, not mocked internals.Recommendation: Redesign the step definitions to use real temporary directory fixtures. This will improve test maintainability, prevent mock brittleness, and align with project testing standards.

1. CI is Failing on Head Commit
538b7c77(Hard Gate)Workflow run #18508 for the head commit shows the following failures:
Per CONTRIBUTING rule 15, every check must pass before a PR can be approved. The lint format failure must be fixed (run
nox -e formatlocally and commit the result). The e2e test failure must also be investigated and resolved.Because the coverage job was skipped, the ≥97% coverage requirement cannot be confirmed for this commit.
Action Required: Fix the format violations, investigate and fix the e2e test failures, push a green build.
⚠️ Security / Input-Validation Observations (Non-Blocking, FYI)
These are observations from the security-focused review pass. None are introduced by this PR — they are pre-existing patterns — but noted for awareness:
object.__setattr__bypasses Pydantic validation in test helpers —_make_settings(**overrides)usesobject.__setattr__(s, key, value)to set fields directly, bypassing Pydantic validators. The current usage setscleanup_sandbox_max_age_hours=1(the minimum valid value perge=1constraint), so this is not a current problem, but the pattern is fragile. Consider usingSettings.model_validate({...})or a proper factory for future robustness.No path-containment check before
shutil.rmtree(pre-existing) —_purge_sandboxes()callsshutil.rmtree(d)on paths filtered by prefix (ca-sandbox-,ca-cow-sandbox-) but there is no assertion that the resolved path is actually withintempfile.gettempdir(). A symlink namedca-sandbox-evilpointing outside/tmpcould be followed. This is a pre-existing concern unrelated to this PR, but worth a follow-up issue.No access-control changes — The fix does not alter who can invoke

Root Cause Analysis
The
unit_testsCI job was failing on the head commite0dd9f1ddue to two issues:@regressiontag causing DB setup overhead: The feature filecleanup_service_cache_invalidation.featurewas tagged@unit @regression. The@regressiontag triggers database setup (temp DB file creation, migration runner initialization) inbefore_scenario. This overhead is unnecessary for these tests since they only exercise filesystem operations and don't need a database. Under parallel CI execution, this DB setup can cause flaky failures._make_settings()usingobject.__setattr__: The helper function bypassed Pydantic validation by usingobject.__setattr__to set field values. While this worked for thecleanup_sandbox_max_age_hours=1case (which is the minimum valid value perge=1constraint), it's fragile and violates the project's code quality standards.Changes Made

Root Cause Analysis (Updated)
The previous fix (

_purge_sandboxes()method reads ALLca-sandbox-*directories fromtempfile.gettempdir()(the system-wide/tmp). In CI with parallel test execution, multiple scenarios from different feature files create staleca-sandbox-*dirs in/tmp. When our Scenario 2 callssvc.purge(), it deletes ALL staleca-sandbox-*dirs in/tmp— including dirs created by OTHER concurrently-running scenarios. This causes those other tests to fail, and their failures cascade back to make our scenarios appear flaky.Fix Applied (commit

Addressed all three blocking issues from review #7671 (HAL9001):
1. CHANGELOG.md — Restored Missing Entries (✅ FIXED)
The branch had a rebase artifact that deleted changelog entries for other merged PRs:
Fix: Replaced the branch-snapshot with master-synchronized CHANGELOG.md, preserving our new #7527 entry at the top of the Unreleased
### Fixedsection.2. CONTRIBUTORS.md — Restored Deleted History (✅ FIXED)
The branch removed multiple pre-existing HAL 9000 contribution entries for:
Fix: Replaced with master-synchronized CONTRIBUTORS.md, preserving all entries + our new #8257 entry.
3. unit_tests CI Failure — Race Condition Fix (✅ FIXED)
The
Settings._instance = Noneline in_make_settings()caused a race condition inbehave-parallel/ CI: concurrent scenario workers could read stale singleton state between the reset and Settings construction. Since Pydantic BaseSettings creates fresh instances per call, the singleton reset was unnecessary and actively harmful in parallel execution.Fix: Removed
Settings._instance = None, keeping only themodel_copy(update=...)pattern which is thread-safe.Quality Gates

Re-Review Summary
Thank you for addressing all three blocking issues from review #7671. Substantial progress has been made — the CHANGELOG.md and CONTRIBUTORS.md rebase artifacts have been restored, and the test design remains solid. However, two blocking issues remain on the current head commit
28ff4d68that prevent approval.✅ Prior Feedback — Status Check

1. CORRECTNESS ✅
self._sandbox_dirs_cache = Noneis placed at the correct location — unconditionally at the end of_purge_sandboxes(), after all deletions complete. This ensures every scan/purge/scan cycle works correctly regardless of how many stale dirs were deleted.2. SPECIFICATION ALIGNMENT ✅
CleanupService. No spec changes needed.3. TEST QUALITY ✅
_IsolatedCleanupServicesubclass overrides_get_sandbox_dirs()to scan a private tmpdir — excellent isolation strategy preventing cross-scenario pollution in parallel Behave runs._make_settings()usesmodel_copy(update=...)— thread-safe, Pydantic-validated, no environment variable mutation.@unit @mock_onlytags are correct: no DB setup required for filesystem-only tests.unit_testsCI is green.4. TYPE SAFETY ✅
# type: ignoreintroduced.typecheckCI is green.5. READABILITY ✅
_IsolatedCleanupService,_make_private_tmp,_make_real_stale_sandbox,_unique_sandbox_name.# Invalidate the cache so...) is clear and references the issue number.6. PERFORMANCE ✅
/tmpis appropriate after a purge cycle.7. SECURITY ✅
shutil.rmtreein_purge_sandboxes()does not validate that resolved paths remain withintempfile.gettempdir()before deleting (a symlink attack vector). This was first noted in review #6101 and is a pre-existing concern unrelated to this PR; a follow-up issue should track it.8. CODE STYLE ✅

Non-Blocking Observations
Branch name convention — Per CONTRIBUTING.md, bug fix branches should use the
bugfix/mN-prefix (for this PR:bugfix/m5-cleanup-service-sandbox-cache-invalidation). The current branch namefix/cleanup-service-sandbox-cache-invalidationis non-standard but is not a merge blocker. Please use the correct prefix on future bug fix branches.CONTRIBUTORS.md trailing newline — The file ends without a trailing newline (the new entry is the last line with no newline after it). This is a minor style issue; consider adding a trailing newline for consistency.
Pre-existing
shutil.rmtreepath containment — As noted in prior reviews,_purge_sandboxes()does not validate that symlink-resolved paths remain within the temp directory before deletion. This is not introduced by this PR and should be tracked in a follow-up issue.Summary

(check
no_duplicates, categoryno_duplicates)Anchor PR #8257 shares identical title and issue reference (#7527) with three other open PRs (#10989, #11010, #11040), all fixing sandbox_dirs_cache invalidation in CleanupService. However, #8257 is unambiguously the canonical: largest diff (383 additions vs 155/109/0), earliest creation (lowest PR number), and only one with explicit comprehensive BDD test coverage mentioned. The others are reattempts/retries, with #11010 being an abandoned placeholder (0 changes). Anchor is not a duplicate; it is the canonical version.
📋 Estimate: tier 1.
Core fix is trivial (one line:
self._sandbox_dirs_cache = None), but the PR adds +383 lines of new BDD feature file and step definitions across 6 files, making this multi-file with format-sensitive test content. All 13 CI gates are failing — likely stale-head rebase conflict causing widespread failures (a known pattern in this repo where old branches lack master patches). Implementer needs cross-file context to diagnose CI failures, understand the BDD test structure, and potentially rebase to pick up master changes. Not mechanical tier-0 work.(attempt #28, tier 1)
