+# V1R4C4 SR-02: Watcher State Cleanup Acceptance
+
+Status: implementation test green
+
+Priority: P1a
+
+Risk: low
+
+Baseline dependency: V1R4C3; should be integrated after SR-01 reliability acceptance or behind SR-01 gate.
+
+## Summary
+
+SR-02 watcher/stuck command cleanup now has a passing test signal:
+
+```text
+11 / 11 tests pass
+```
+
+The fix validates stuck command detection across both `.json` and `.md` command state formats.
+
+## Fix Summary
+
+### 1. Stuck command detection logic
+
+The controller logic in `autonomous_controller.py` was corrected.
+
+Previous failure mode:
+
+- parsed JSON was accessed through `.string('ts')`, which is empty for parsed JSON;
+- stuck threshold comparison against `stale_start` was incorrect;
+- stale/stuck state could be missed even when command metadata was old enough.
+
+Correct behavior:
+
+```python
+ts = data.get('ts', 0)
+```
+
+The command timestamp is now read from parsed data and compared using the correct time-based stale/stuck threshold.
+
+### 2. Test fixture mtime alignment
+
+The test fixture now sets the filesystem modification time of generated `.md` files to match the stored stuck timestamp.
+
+This is required because stuck detection uses both command metadata and file age semantics.
+
+Corrective test fixture behavior:
+
+```python
+os.utime(path, (ts, ts))
+```
+
+This ensures `.md` command files with a timestamp older than the stuck threshold are actually visible to `h_stuck()` as stuck.
+
+## Coverage
+
+Validated formats:
+
+- `.json` command state files;
+- `.md` command state files.
+
+Validated behavior:
+
+- old command timestamps are recognized as stuck;
+- current/non-stale command timestamps are not falsely marked stuck;
+- `.md` fixtures behave consistently with stored `ts` metadata;
+- detection behavior is consistent across file formats.
+
+## Acceptance Result
+
+```text
+all tests: pass
+count: 11
+```
+
+## Integration Guidance
+
+SR-02 is eligible for V1R4C4 integration after SR-01 confirms GitOps/Gitea reliability guardrails are stable.
+
+SR-02 must not bypass SR-01 because watcher cleanup changes autonomous controller behavior. It should be integrated behind the same safe-mode assumptions introduced by SR-01.
+
+## Remaining Checks Before Merge
+
+1. Confirm the exact implementation commit containing `autonomous_controller.py` and test fixture changes.
+2. Run SR-01 runtime acceptance first.
+3. Re-run the SR-02 test suite after rebasing/integrating with V1R4C4 reliability branch.
+4. Run global runtime acceptance:
+
+```text
+getRuntimeStatus -> getBaseline -> createBranch -> createPatch
+```
+
+## Decision
+
+Treat SR-02 as test-green and ready for controlled integration, not as independently deployable before SR-01.

-# V1R4C4 SR-01 Deployment Acceptance: Gitea Branch Consistency Sentinel
-
-Date: 2026-07-10
-
-Status: healthy
-
-Baseline at validation: V1R4C3
-
-Runtime status at record time: active
-
-## Acceptance Summary
-
-The Gitea branch consistency sentinel is deployed and operating successfully.
-
-Observed service result:
-
-```json
-{
-  "status": "healthy",
-  "unhealthy_checks": []
-}
-```
-
-No unhealthy checks were reported.
-
-## Implemented Components
-
-### 1. Sentinel script
-
-Path:
-
-```text
-/data/aios-gitops/workspace/scripts/reliability/gitea_branch_consistency_sentinel.py
-```
-
-Purpose:
-
-- compare Gitea branch metadata against actual Git branch state;
-- detect branch metadata drift;
-- emit structured JSON result;
-- optionally emit autonomous safe-mode state when unhealthy.
-
-The deployed check compares Gitea branch metadata available through the local Gitea endpoint against the actual git branches in the repository directory.
-
-Endpoint used:
-
-```text
-127.0.0.1:3000
-```
-
-### 2. Safe-mode helper
-
-Path:
-
-```text
-/data/aios-gitops/workspace/scripts/reliability/autonomous_safe_mode.py
-```
-
-Purpose:
-
-- provide safe-mode output/formatting helper;
-- support autonomous controller behavior when drift is detected.
-
-### 3. systemd timer
-
-Unit:
-
-```text
-gitea-branch-consistency-sentinel.timer
-```
-
-Schedule:
-
-```text
-every 5 minutes
-```
-
-Purpose:
-
-- continuously monitor Gitea branch consistency;
-- reduce mean time to detection for branch metadata drift;
-- provide recurring health evidence.
-
-### 4. systemd service
-
-Unit:
-
-```text
-gitea-branch-consistency-sentinel.service
-```
-
-Execution:
-
-```text
-gitea_branch_consistency_sentinel.py --emit-safe-mode --json
-```
-
-Purpose:
-
-- execute consistency sentinel;
-- log structured JSON output;
-- emit safe-mode state when the sentinel becomes unhealthy.
-
-### 5. Workspace symlink fix
-
-A broken `reliability` directory symlink pointing outside the workspace was replaced with actual files.
-
-Reason:
-
-- systemd sandboxing prevents following the prior external symlink safely;
-- deploying actual files inside the workspace makes service execution deterministic.
-
-## Reliability Impact
-
-This closes the core SR-01 monitoring gap:
-
-```text
-Gitea branch metadata drift
-        ↓
-detected within timer interval
-        ↓
-structured JSON health record
-        ↓
-autonomous safe-mode emission if unhealthy
-```
-
-The timer now provides continuous verification every 5 minutes.
-
-## Current Result
-
-```text
-status: healthy
-unhealthy_checks: none
-timer: active every 5 minutes
-service: emits JSON with --emit-safe-mode
-```
-
-## Acceptance Decision
-
-SR-01 deployment guardrail is accepted as healthy for V1R4C4 reliability freeze readiness.
-
-This does not yet promote V1R4C4. It provides one required acceptance input for V1R4C4.
-
-## Remaining Before V1R4C4 Promotion
-
-1. Confirm SR-02 watcher cleanup remains test-green after integration.
-2. Run GitOps runtime acceptance:
-
-```text
-getRuntimeStatus -> getBaseline -> createBranch -> createPatch
-```
-
-3. Confirm no new Gitea branch metadata drift after acceptance writes.
-4. Prepare V1R4C4 reliability baseline proposal.
-5. Keep SR-04 Portal AIOS Integration gated until SR-01 and SR-02 are both accepted.
