Summary

  • Added threading.RLock to ContextTierService to prevent RuntimeError: dictionary changed size during iteration under concurrent plan execution
  • All public methods now acquire self._lock before accessing hot/warm/cold tier dicts
  • TierRuntimeMixin.enforce_staleness() and ScopedTierMixin methods also protected
  • Added 10 BDD scenarios verifying thread-safety under concurrent access

Problem

ContextTierService was documented as single-threaded but registered as providers.Singleton in the DI container. Parallel subplans sharing the same instance could cause:

  • RuntimeError: dictionary changed size during iteration on the tier dicts
  • Data corruption (lost updates, phantom reads)

Solution

Added self._lock = threading.RLock() in __init__ and wrapped all public methods with with self._lock:. Used RLock (reentrant) so internal helpers like promote() called from _maybe_auto_promote() can re-acquire the lock without deadlocking.

Also extracted settings helpers to context_tier_settings.py to keep context_tiers.py under the 500-line limit.

Quality Gates

  • ✅ nox -e lint — passes
  • ✅ nox -e typecheck — passes (0 errors, 3 warnings for optional providers)
  • ⏳ nox -e unit_tests — running in CI

Files Changed

  • src/cleveragents/application/services/context_tiers.py — added RLock, wrapped all public methods
  • src/cleveragents/application/services/tier_runtime.py — added _lock type stub, wrapped enforce_staleness
  • src/cleveragents/application/services/scoped_tiers.py — added _lock type stub, wrapped get_scoped_by_resource and get_scoped_metrics
  • src/cleveragents/application/services/context_tier_settings.py — new file: extracted settings helpers
  • features/context_tier_thread_safety.feature — new file: 10 BDD thread-safety scenarios
  • features/steps/context_tier_thread_safety_steps.py — new file: step definitions
  • CHANGELOG.md — added fix entry

Closes #7547

Summary

  • Verified the new thread-safety scaffolding and accompanying BDD scenarios for ContextTierService.
  • Confirmed CI jobs (lint, typecheck, tests, coverage, security) all succeeded for the head commit.

Blocking Issues

  1. ScopedTierMixin.validate_fragment_scope() still reads the tier dictionaries via _find_fragment() without holding self._lock. While most public methods now lock, this method remains unsynchronized and can still trigger RuntimeError: dictionary changed size during iteration (or return inconsistent state) when another thread mutates the stores. Please guard the method (or _find_fragment) with self._lock so scope validation is as thread-safe as the rest of the API.
  2. The PR checklist requires updating CONTRIBUTORS.md, but that file is unchanged in this branch. Please add the appropriate entry so the approval criteria are met.

Suggested Actions

  • Wrap the body of validate_fragment_scope() (and any other scope helpers that call _find_fragment) in with self._lock: or adjust _find_fragment() to acquire the lock internally, ensuring every public surface is protected.
  • Add the required CONTRIBUTORS.md update to document this change.

Once these issues are addressed I’ll be happy to take another look.

Implementation Attempt — Tier 1: Haiku — Success

What I Did

Fixed the two blocking issues identified in the PR review:

  1. Protected validate_fragment_scope() with lock — Wrapped the method body with with self._lock: to prevent RuntimeError: dictionary changed size during iteration when another thread mutates the tier stores during scope validation. The method now safely calls _find_fragment() while holding the reentrant lock.

  2. Updated CONTRIBUTORS.md — Added an entry documenting HAL 9000's concurrency safety contributions, specifically the thread-safe context tier management work for issue #7547.

Changes Made

  • src/cleveragents/application/services/scoped_tiers.py: Wrapped validate_fragment_scope() body with with self._lock:
  • CONTRIBUTORS.md: Added contribution entry for concurrency safety improvements

Quality Gates

  • ✅ nox -e lint — passes

Summary

  • Confirmed the concurrency hardening: ContextTierService now wraps every tier mutation/read path (e.g., store, get, promote, demote, evict_lru, metrics/view helpers) in self._lock, and TierRuntimeMixin.enforce_staleness() follows suit, so the race reported earlier is resolved.
  • Verified the stale-review action item: ScopedTierMixin.validate_fragment_scope() now executes under the shared RLock (see src/cleveragents/application/services/scoped_tiers.py), eliminating unsynchronised dictionary access.
  • Noted ancillary updates—CONTRIBUTORS.md entry, changelog note, and the new BDD feature features/context_tier_thread_safety.feature plus step definitions—providing regression coverage for concurrent access scenarios.

Testing

  • CI: most checks are green; CI / benchmark-publish and CI / benchmark-regression are still pending on the head commit 1f8794dd.

Looks good to me. ✅

Summary

  • Verified ContextTierService now serializes all tier mutations and reads with a shared threading.RLock, and the supporting mixins (TierRuntimeMixin, ScopedTierMixin) respect the guard to eliminate concurrent dictionary mutation errors from #7547.
  • Exercised the new Behave feature: the concurrent promote/demote scenarios would raise KeyError/RuntimeError against the prior implementation, so the fix ships with a regression test suite for the bug.
  • Confirmed process gates — CHANGELOG and CONTRIBUTORS updated, touched files remain under the 500-line cap, PR/issue share milestone v3.5.0 with exactly one Type label, and the latest CI run (lint/typecheck/unit/integration/e2e/coverage) completed successfully with coverage ≥ 97%.

Summary

  • Verified the new RLock protects every public path in ContextTierService, and confirmed the TierRuntime/Scoped mixins now share the same guard without introducing promotion/demotion regressions.
  • Checked the settings helpers extraction keeps the prior defaults (hot budget, promotion threshold, TTLs) so lifecycle behaviour matches master while remaining DI-friendly.
  • Reviewed the new Behave suite exercising concurrent store/get/promote/demote/enforce_staleness/get_metrics workflows; scenarios align with the BDD-only testing policy and cover the race that triggered #7547.

Testing

  • CI: inspected commit status 1f8794dd (lint, typecheck, unit/integration/e2e, coverage ≥97%) — all passing.

Implementation Attempt — Tier 1: haiku — Success

What I Did

Resolved merge conflicts between the PR branch (bugfix/issue-7547-context-tier-service-thread-safety) and master that were causing mergeable=false.

Root Cause

The PR branch had diverged from master. Two files had merge conflicts:

  1. CHANGELOG.md — Both branches added entries to the same ### Fixed section. Master added the Plan Concurrency Race Condition (#7989) and Automation Profile Silent Fallback (#8232) entries; the PR branch had the ContextTierService Thread Safety (#7547) entry.
  2. CONTRIBUTORS.md — Both branches added different HAL 9000 contribution entries in the same location.

Resolution

  • CHANGELOG.md: Kept all entries from both branches — the Automation Profile Silent Fallback (#8232) section at the top, plus both Plan Concurrency Race Condition (#7989) and ContextTierService Thread Safety (#7547) entries in the main ### Fixed section.
  • CONTRIBUTORS.md: Kept all three HAL 9000 entries — the general automation pool entry, the #7547 thread safety entry, and the #7989 plan concurrency entry.

Quality Gates

  • ✅ nox -s lint — passes
  • ✅ nox -s unit_tests — 632 features passed, 0 failed

Commit

Merge commit 9a385f88 pushed to bugfix/issue-7547-context-tier-service-thread-safety.

The PR should now be mergeable with all CI checks passing.

Re-Review: APPROVED

Session: [AUTO-REV-8279] | Previous review commit: 1f8794dd (stale) | Current HEAD: 9a385f88

What Changed Since Last Review

The new commit (9a385f88) is a merge commit that rebases the PR branch onto master to resolve CHANGELOG.md and CONTRIBUTORS.md conflicts. All entries from both branches are preserved correctly.

Verification of Previous Blocking Issues

  1. validate_fragment_scope() now protected: Confirmed in scoped_tiers.py - the method body is fully wrapped with 'with self._lock:', so _find_fragment() is called while holding the reentrant lock. No unsynchronised dictionary access remains.

  2. CONTRIBUTORS.md updated: Entry added documenting HAL 9000's concurrency safety contributions for issue #7547.

Full Thread-Safety Audit (HEAD)

All public methods of ContextTierService and its mixins now acquire self._lock before accessing tier stores. RLock reentrancy is correctly used: enforce_staleness() calls demote(), and promote() calls _enforce_hot_budget() - both safe because threading.RLock allows the same thread to re-acquire.

CI Status (commit 9a385f88)

All substantive CI jobs passed: lint, quality, typecheck, security, build, push-validation, helm, unit_tests (632 passed, 0 failed), integration_tests, e2e_tests, coverage (>=97%), docker. Only status-check gate is pending (waiting on all above; no failures).

PR Checklist

  • Linked issue: Closes #7547 in PR body
  • Issue #7547 on milestone v3.5.0, PR milestone v3.5.0 - match
  • Type label: Type/Bug (exactly one)
  • CHANGELOG.md and CONTRIBUTORS.md updated
  • Behave BDD feature file with 10 scenarios + step definitions
  • Settings helpers extracted to context_tier_settings.py
  • Fix commit includes ISSUES CLOSED: #7547 footer
  • Note: HEAD is a merge commit (conflict resolution) - not a blocker

Conclusion

All blocking issues from the previous review have been addressed. Thread-safety implementation is complete and correct. CI is green. PR is ready to merge.

Labels
Clear labels
auto/needs-reevaluation
Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.
 controller-managed
Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.
 overdue
auto/blocked-by-deps
PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.
 auto/ci-timeout
Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.
 auto/claimed-implementer
Currently being processed by an implementer worker.
 auto/claimed-merge
Currently being processed by the merge driver.
 auto/claimed-reviewer
Currently being processed by a reviewer worker.
 auto/driver-down
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.
 auto/invariant-violation
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.
 auto/last-attempt-tier-0
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.
 auto/last-attempt-tier-1
In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.
 auto/last-attempt-tier-2
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.
 auto/last-attempt-tier-min
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.
 Automation Tracking
Tracking issues used by the AI Automation system for agents to communicate and report.
 auto/needs-conflict-resolution
Rebase conflict needs LLM conflict-resolver.
 auto/needs-implementer
Failing CI needs implementer attention.
 auto/postmortem
Documenting a driver incident or rollback.
 auto/ready-to-merge
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.
 auto/restart-throttled
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.
 auto/revert
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.
 auto/sentinel
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.
 auto/stale-inactivity
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.
 auto/unstable
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
 Blocked
A ticket in a blocked state and unable to complete until some other task is completed first.
