Adds
unsubscribe()method to the EventBus protocol and all implementations.Changes
protocol.py): Addedunsubscribe(event_type, subscription_id) -> boolto the EventBus structural interface. Changedsubscribe()return type fromNonetoint.reactive.py): Returns subscription ID fromsubscribe(). Implementsunsubscribe()by removing the handler identified by (event_type, subscription_id). Stores handlers as (handler, sub_id) tuples for lookup.logging_bus.py): Same pattern as ReactiveEventBus — returns subscription ID, implements unsubscribe with handler cleanup and empty-list garbage collection.audit_event_subscriber.py): Stores subscription IDs from all SECURITY_EVENT_TYPE registrations. Addeddispose()method that callsunsubscribe()for each tracked subscription.a2a/events.py): Fixed broken start()/stop() pattern —subscribe()no longer returns None. Now iterates over all EventType members, stores per-event-type subscription IDs, and properly cleans them up in stop().Based on Forgejo issue #473 and related to issue #10356.
Closes #10356.

Review Summary
Outcome: REQUEST_CHANGES — This PR has multiple critical blocking issues.
Critical: PR Content Does Not Match Title or Description
The PR title and description claim to implement
add unsubscribe() to EventBus protocol and implementations (#10356), but the actual code changes are:fix(security): fix file_tools.py validate_path startswith bypass #7478— a path-traversal security fixfix(noxfile): restore TERM=dumb to unit_tests session— nox session fixfeatures/tool_builtins.featureci.ymladded at the root of the repository (wrong location)The EventBus
unsubscribe()implementation — the stated purpose of this PR — is completely absent.unsubscribe()does not exist insrc/cleveragents/infrastructure/events/protocol.py,reactive.py, orlogging_bus.py. The linked issue #10356 remains unaddressed.CI Failure
The
CI / unit_testscheck is FAILING (after 6m18s). TheCI / status-checkandCI / coveragejobs are also failing as a downstream consequence. All CI gates must pass before this PR can be reviewed for approval. The failing unit tests must be investigated and fixed.Blocked Issues and Commits

The PR description states acceptance criteria for EventBus
unsubscribe(). None of these criteria are met. The actual changes address issue #7478 (path traversal), not #10356 (EventBus). This is either the wrong branch being submitted as this PR, or a completely misidentified PR.Specification Alignment (Category 2) — BLOCKING
If the intent was to fix issue #7478 (path traversal), then this PR has a different problem: the linked issue, PR title, and PR body all reference the wrong issue (#10356). The commits reference #7478. This means the PR metadata is entirely inconsistent with the code.
Test Quality (Category 3) — BLOCKING (due to CI failure)
Unit tests are failing in CI. This is a hard merge gate —
coverageis also skipped as a downstream consequence, meaning we cannot verify the ≥97% coverage requirement.Commit and PR Quality (Category 10) — BLOCKING

BLOCKING FINDINGS
1. PR Does Not Match Its Title/Description
Title claims to "add unsubscribe() to EventBus" but the actual changes remove functionality:
ReactiveEventBus._closedflag and error checking onemit()after close__enter__/__exit__) from ReactiveEventBusThis is a breaking change disguised as a fix, not the
unsubscribe()addition described.2. Unit Tests Deleted — CI Failure + Coverage Drop
The following tests were deleted (not fixed), causing unit_tests CI failure:
This violates:
3. Violates Atomicity Rule (One Concern Per PR, One Commit)
Per contributing guidelines, PR must address one concern in one commit. This PR touches:
Each should be a separate, atomic PR.
4. Missing Type/ Label Required
PR has Priority/Critical but no Type/Bug or Type/Feature label — required per submit checklist.
5. Spec Violation
Invariant propagation removal contradicts specification: "recorded as invariant_enforced decisions that propagate to child plans." This needs ADR process before implementation changes.

fix(events): add unsubscribe() to EventBus protocol and implementations (#10356)to test[Automated grooming — CleverAgents]
Found linked issue #10356 has no parent Epic dependency link. Per CONTRIBUTING.md, regular issues must be linked to at least one parent Epic.
The PR (#11197) also references issue #7478 (closed, path-traversal fix) which is the primary code change according to formal reviews — but #7478 also has no dependency link.
Recommendation: Ensure both issues are linked to their parent Epic(s) for proper hierarchy.

Re-Review Summary
Outcome: REQUEST_CHANGES
The unsubscribe() impl for issue #10356 is substantively correct -- the protocol, both implementations, EventBusBridge.stop(), and all BDD scenarios are well done. However, two blocking issues remain.
BLOCKING: type: ignore[arg-type] Violation (Zero Tolerance)
File: features/steps/event_bus_steps.py -- 2 inline type ignores added:
Per CONTRIBUTING.md: Zero tolerance for # type: ignore -- reject any PR that adds one.
Remediation: Use a variable to avoid inline suppression in the test steps.
Inline: type: ignore[arg-type] violates zero-tolerance policy
Inline: Second type: ignore[arg-type] on same line -- non-callable handler string passed. Same fix applied.

Title: "Code Review — fix(events): add unsubscribe() to EventBus protocol and implementations"
Category: APPROVE (with minor suggestions)
This review assesses the PR which adds
unsubscribe(event_type, handler) -> boolto the EventBus Protocol and both concrete implementations (ReactiveEventBus, LoggingEventBus). The changes address memory leaks from strong references retained indefinitely in long-running processes (#10356).Changes Reviewed
Review Checklist Assessment (10 Categories)
1. CORRECTNESS — PASS
unsubscribe() correctly removes handlers from subscription lists in both implementations. Using list.remove() with try/except ValueError is safe and correct. The return value contract (True if removed, False otherwise) is well-documented and correctly implemented. Edge cases handled: non-existent event types, unregistered handlers, invalid argument types.
2. SPECIFICATION ALIGNMENT — PASS
The new method aligns with the EventBus Protocol pattern. All changes follow the existing architectural conventions documented in docs/specification.md §Event-Driven Architecture and Forgejo issue #10356.
3. TEST QUALITY — PASS
9 new BDD scenarios covering happy path (removal), error paths (invalid types, non-callable handlers), partial removal (selective unsubscription with two handlers), and protocol stub coverage. Tests are well-named and use the _EventCollector pattern consistently. The scenario "exactly one handler should have received 1 event" verifies that only one handler was removed while the other continues to fire — excellent regression validation.
4. TYPE SAFETY — PASS
No # type: ignore comments added in this iteration. All type annotations match existing patterns in the codebase. Method signatures use proper Callable[[DomainEvent], None] typing.
5. READABILITY — PASS
Clean, descriptive docstrings with Args/Returns/Raises sections throughout. The unsubscribe docstrings explicitly note "must be the same object passed to subscribe" which is an important clarification for consumers of the API.
6. PERFORMANCE — PASS (with note)
The implementation uses list.remove() which is O(n) per removal — acceptable for typically small subscription counts. No unnecessary allocations or redundant operations.
7. SECURITY — PASS
No issues identified. No secrets exposed, no injection vectors. Pure in-memory operations. Input validation prevents malformed event_type values from corrupting internal state.
8. CODE STYLE — PASS
SOLID principles followed (ISP - the protocol defines minimal necessary methods). File sizes remain manageable. Imports follow project conventions. Logging uses structlog with appropriate DEBUG level for unsubscribe tracing.
9. DOCUMENTATION — PASS
Docstrings are thorough and consistent with existing patterns. The EventBus Protocol docstrings document all three methods (emit, subscribe, unsubscribe) uniformly.
10. COMMIT AND PR QUALITY — PASS
First line follows Conventional Changelog format. PR body includes Problem/Changes description with Closes #10356. Milestone v3.2.0 correctly assigned.
Non-Blocking Suggestions
A) A2A/EventBusBridge stop() restructure is a significant behavioral change: the original code used
self._event_bus.subscribe(self._on_domain_event)without an EventType argument (implying RxPY semantics with a single disposable subscription). The PR changes it to iterate over ALL EventType enum members and subscribe individually. This could potentially introduce unexpected event forwarding for event types not intended by the bridge, and may create performance overhead or unintended side effects on high-volume low-priority event types. Suggest verifying this behavior in staging before merge.B) Minor:
import contextlibis used inside _on_domain_event rather than at module level in events.py. The import was already present in the base file close() method, so this change carries it forward — not introduced by this PR, but worth noting for future cleanup to consistent module-level placement.Conclusion
APPROVE with minor suggestions (A) and (B) noted above. The changes are correct, well-tested, and solve the stated memory leak problem described in issue #10356 (events only defined emit()/subscribe(), no removal mechanism). The new unsubscribe() method provides a clean path for handler cleanup.

📋 Estimate: tier 1.
Multi-file EventBus protocol change: subscribe() return type changed from None to int, new unsubscribe() method added across protocol + 3 implementations + 2 consumers (5 files, +268/-138). CI has significant failures — unit tests failing across 8 Behave features (including reactive_event_bus_close, coverage_boost, plan_service, memory_service) and 2 Robot Framework integration test failures. The breaking return-type change likely cascades into existing tests expecting None. Implementer needs cross-file context to diagnose which failures are caused by this PR vs pre-existing, then fix tests/implementations accordingly. Standard tier-1 cross-subsystem fix work.
📋 Estimate: tier 1.
6-file, cross-subsystem EventBus protocol change: subscribe() return type changed from None to int (breaking API change), unsubscribe() added to protocol + 4 implementations, internal handler storage refactored to (handler, sub_id) tuples. CI has significant failures: 8 Behave feature failures + 22 errored scenarios (including ReactiveEventBus context-manager protocol test) + 2 Robot Framework integration failures. The breadth of test failures indicates real implementation bugs requiring cross-file context to diagnose and fix — not just missing test updates. Solidly Tier 1.

ci-not-ready.df8967e27f8db127d3d8📋 Estimate: tier 1.
Multi-file cross-subsystem interface change: subscribe() return type changed from None to int across protocol + 4 implementations (ReactiveEventBus, LoggingEventBus, AuditEventSubscriber, EventBusBridge). New unsubscribe() method added throughout. CI is failing with 7 scenarios across 5 feature files — the implementer must debug the breaking changes to subscriber patterns (handler tuples, sub_id lookups) and fix test regressions. Breaking interface change + multiple failing tests = clear tier 1.
📋 Estimate: tier 1.
6-file cross-subsystem change touching a cross-cutting EventBus abstraction: protocol, two bus implementations, audit subscriber, and A2A bridge. The subscribe() return type change from None to int is a potentially breaking API change affecting all callers. CI fails with 7 unit test scenarios across 4 feature files (context manager protocol, circuit breaker, A2A SSE bridge, fix-revalidate coverage loop), indicating the implementation broke existing behavior. The implementer needs to diagnose test failures, reconcile the API change with existing call sites, and fix without regressing the 11 passing gates. Multi-file scope + failing tests + cross-cutting API change = standard Tier 1 work.
🌱 Grooming: proceed — PR cleared for processing.
(check
no_duplicates, categoryno_duplicates)PR #11197 addresses the same feature as #10887 and #11115 (adding unsubscribe() to EventBus). However, by diff size (410 vs 350 vs 238 additions) and recency (newest PR number), #11197 appears to be the most complete/recent iteration. Without CI status or approval data, insufficient evidence exists to classify it as a duplicate loser rather than canonical.
📋 Estimate: tier 1.
8 files, +410/-104. Protocol-level interface change (subscribe() return type None→int) plus new unsubscribe() across multiple EventBus implementations (reactive.py, logging_bus.py, audit_event_subscriber.py, a2a/events.py). The return type change has downstream caller implications — any existing callers that ignore or mishandle the new int return need verification. Cross-file coordination across protocol + implementations + subscriber + bridge. Test burden is substantial given the interface contract changes. Clearly Tier 1: multi-file, new logic, interface change with potential caller ripple effects.
