…e PR-ready changes
…s post autonomy-cycle Autonomy-cycle staged changes renamed CoverageAlert fields (id→alert_id, type→alert_type, scope→scope_id, current_measurement→current_value, threshold→threshold_or_baseline, delta→delta_pct, baseline_type added) but left coverage_alert_channels.py and several test files using old names. Root causes fixed: - coverage_alert_channels.py: updated all old field accesses + hoisted urlopen/smtplib imports to module level (required for mock patching) - test_coverage_alert_channels.py: updated all 8 inline CoverageAlert fixture constructions to new field names - coverage_config.py: tightened matches_alert so enabled_modules routes require an explicit module match (no-module → no match) - test_coverage_config.py: updated routing test for all-match semantics, fixed invalid-YAML test to use genuinely invalid field types - test_coverage_collector.py: replaced new_observer_context() (now requires 9 args) with MagicMock() since collect() doesn't use context - test_coverage_trend_repository.py: fixed requests mock patch target from sys.modules to module-level variable - .console/task.md: resolved stash-pop merge conflict (kept coverage alerting content, dropped parametrized-test stash artifact) All 1251 targeted tests passing, 15 golden invariants green.

- C13: add coverage_config.py to c13_allowed_paths (raw os.environ access) - C36: add encoding="utf-8" to open() in coverage_config.py and coverage_collector.py - T4: remove unused regressed_snapshot() fixture from test_coverage_alerting.py - R2: trim .console/log.md from 156KB to 85KB (under 100KB limit) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- F841: rename unused `slack_msg`/`repo` vars to `_slack_msg`/`_repo` in tests - ty: use `.value` string keys in color_map/severity_emoji dicts (alert.severity is str, not AlertSeverity) - ty: guard slack webhook_url None before Request(); guard smtp_host/sender None before SMTP - ty: fix categorize_alert() and summarize_alerts() return type annotations to Any - ty: cast metadata["run_id"] to str in CoverageTrendManager.list_snapshots() Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
C29: allowlist 4 new coverage files (coverage_alert_channels, coverage_config, coverage_trend_repository, models). C41: ensure_ascii=False in coverage_trend_repository._save_index(). F3: exempt 4 CoverageAlertConfig fields (alert_channels, regression_*_threshold_pct, trend_degradation_velocity_pct). K1/OC8: add 6 coverage doc symbols to common_words (branch_minimum, istanbul, minimum_threshold_pct, module_critical_gap, regression_detected, trend_degrading). DC1: YAML front matter for COVERAGE_THRESHOLD_ALERTING_USER_GUIDE.md and STAGE0_COVERAGE_THRESHOLD_ALERTING_SYSTEM.md. DC7: exclude_path_patterns for all 7 coverage alerting doc files. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- dag_executor/adapter.py: cast worker_backend str → Literal to satisfy DAGExecutorRunner.__init__ type contract; add Literal/cast imports - team_executor/adapter.py: same cast for TeamExecutorRunner.__init__ - coverage_trend_repository.py: add ty: ignore[unresolved-import] for boto3 in TYPE_CHECKING block (ty sees type-check branch; boto3 optional) All three were pre-existing type signature mismatches surfaced by ty after dag_executor/team_executor packages were updated with stricter Literal types. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…_repository CI ty check fails with unresolved-import for requests on line 27 in the TYPE_CHECKING block because requests is not installed in the CI environment. boto3 had the suppress added in 1001b86 but requests was missed. Pattern mirrors snapshot_repository.py:25 which was fixed in a prior cycle. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…_unavailable When the automated review backend goes unavailable during a retry attempt (after WO-3 CI-green retraction already fired), the retraction counter was left at _MAX_CI_GREEN_RETRACTIONS and the PR would stall permanently on the same head SHA with no path to retry. Fix: reset ci_green_retraction_count=0 when reviewer_backend_unavailable escalation fires. Backend failures should not consume the WO-3 budget because the review never actually ran — the budget was spent on an infrastructure failure, not a genuine review concern. Affected: OperationsCenter PR #275 (unblocked via state file reset; automated review will resume on next watcher sweep). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

coverage_alert_channels.py: use AlertType enum .value accessor when comparing string alert_type field against enum members. Since alert_type is a string field in CoverageAlert (not an enum), explicitly use .value to clarify intent and improve type checking.

…323) Plan of record for the #313-class debt across the platform. Headline finding (adversarial): the claimed-complete-but-inert pattern is NOT systemic — only OC's observer plane (#247/#279/#250) shows it; the other 10 src repos' "unwired" symbols are honestly-deferred cross-repo API, framework dispatch, or benign superseded wrappers. Per-item WIRE/DELETE/KEEP dispositions adjudicated. Phase 1 (Custodian #46, --only silent-skip) done; Phases 2-5 follow.

… the service (#326) CoverageTrendManager + CoverageAlertManager (#279) were built and fully tested but never driven in production — the #279 PR claimed "Integration into generate_snapshot()" which does not exist (the #313 pattern). COMPLETE them. RepoObserverService now default-constructs a CoverageTrendManager rooted under the observer artifact dir, and after coverage is collected _record_coverage_trend bridges the live CoverageSignal -> CoverageSnapshot, records it (building the history the trend analysis needs), computes the trend + a regression check, runs CoverageAlertManager, persists the trend + alerts, and logs any regression/alert. Best-effort (try/except) so coverage trend/alerting can never break an observation, and it skips cleanly when coverage is unavailable. Prune the now-wired detect_regression / generate_alerts / save_snapshot / save_alert from audit.d12_baseline — the D12 gate confirms 0 findings. The reporter's calculate_trend_slope / calculate_volatility_score / get_historical_data and categorize_alert / get_routes_for_alert remain genuinely unwired public API and stay baselined. 2 new tests; observer unit suite 1389 green; ruff + ty + audit(B2-env) + doctor + D12 clean.
