- status: completed
- focus: Permission validation + operational synthesis update.

Summary
- ✅ Confirmed read access to
/home/matrix-lite/state/persistent-chat/model-heartbeat.json.
- 🔄 Model heartbeat (curation) recovered: The 18:33Z run succeeded (
rc=0, acpx_rc=0, action=updated) after ~3 days of acpx_rc=5 failures.
- ⚠️ Curator-journal discrepancy: Last entry (18:32:55Z) still records deterministic fallback /
rc=5; file mtime is 18:32:55Z and has not yet reflected the 18:33Z success.
- ❌ Operational synthesis agent remains fragile: failures at 18:33Z (report not written), 18:51Z (
SIGTERM/timeout), and 19:01Z (SIGTERM).
- 🟢 No new user messages since ~May 25 09:54Z. Session stable.

| actions.jsonl | 25 open items | Includes heartbeat diagnosis, semantic cleanup, candidate review |
Findings
- Heartbeat recovery — The 18:33Z model-heartbeat run is the first successful curation since ~May 23.
curated_changed=true and reflection_changed=true confirm actual file updates occurred.
- Curator-journal lag — The journal's last paragraph (18:32:55Z) describes a failure, and its mtime matches that timestamp. It may catch up on the next cycle, or there may be a race between journal write and file-modify detection.
- Synthesis fragility persists — Three additional synthesis failures occurred after the 17:13Z success. Root cause appears to be
SIGTERM (timeout) or validation race, not model-heartbeat failure.
Actions
| # | Action | Owner | Status |
|---|--------|-------|--------|
| 1 | Monitor heartbeat stability: verify next run (~19:26Z) succeeds | operational_synthesis | monitoring |
| 2 | Investigate synthesis failure root cause (SIGTERM/timeout) | assistant | open |
| 3 | Clean stale notices (entries 12-15, 16-19, 33-34 are resolved/obsolete) | assistant | open |
| 4 | If next heartbeat fails, re-open acpx_rc=5 diagnosis | assistant | deferred |
Blockers
- None new. Bash wildcards remain denied; read/write native tools work.
Backlog Plan
- If the 19:26Z heartbeat also succeeds, mark the acpx_rc=5 issue as resolved and shift focus to semantic-memory cleanup and candidate review.
- If synthesis continues failing, escalate to daemon timeout/validation logic review.

## Summary
- ✅ Confirmed read access to `/home/matrix-lite/state/persistent-chat/model-heartbeat.json`.
- 🔄 **Model heartbeat (curation) recovered**: The 18:33Z run succeeded (`rc=0`, `acpx_rc=0`, `action=updated`) after ~3 days of `acpx_rc=5` failures.
- ⚠️ **Curator-journal discrepancy**: Last entry (18:32:55Z) still records deterministic fallback / `rc=5`; file mtime is 18:32:55Z and has not yet reflected the 18:33Z success.
- ❌ **Operational synthesis agent remains fragile**: failures at 18:33Z (report not written), 18:51Z (`SIGTERM`/timeout), and 19:01Z (`SIGTERM`).
- 🟢 No new user messages since ~May 25 09:54Z. Session stable.
