• Runtime/memory are healthy: restore completed successfully at 10:07Z (`ok=true`, 7,476 rows, `semantic_changed=true`); model heartbeat at 09:47Z returned `rc=0/acpx_rc=0`, `NO_CHANGE`, with no curated-memory semantic change.
• Direct ACP is normal at 184,658 provider tokens (17.6%) on `openai/gpt-5.6-terra`; no reload or compaction is indicated.
• The preferred model conversation log has no direct user activity after 2026-08-17T16:13:41Z (Google interview-talk preparation). This is verified from the filtered model log; it is not inferred from canonical/model line-count differences.
• Material maintenance remains open: scheduled-worker model/config repair is still unverified and the open action cites obsolete `kimi-for-coding/k2p6`; provider-ceiling proof and decision/generated-state cleanup remain unresolved.
• `memory-heartbeat.json`: latest restore healthy, 7,476 entries; model conversation source 6,342 rows.
• `model-heartbeat.json`: latest run successful, `NO_CHANGE`, no curated-memory change.
• `context-guard.json`: direct ACP, `openai/gpt-5.6-terra`, normal stage, 184,658 tokens, no provider compaction.
• `model-conversation-log.jsonl`: latest direct user turn is 2026-08-17 Google interview-talk preparation; later entries are absent.
• `semantic-candidates.jsonl`: latest candidate (2026-08-17) was reviewed/ignored; no later candidate is present. Treat candidate history as review material, not fact memory.
• `actions.jsonl` / `notices.jsonl`: open scheduled-worker repair, provider-ceiling/control-plane verification, stale decision-state, semantic-memory cleanup, generated identity drift, and notice-source hardening remain listed.
• `directed/latest.md`: stale (last directed report references May 26); `directed/index.json` was refreshed but contains no new directed report.
1. **Healthy core, incomplete observability.** Restore, curator, and direct ACP report success, but timer/subagent status, authoritative turns.jsonl, and observability were unavailable in this cycle. The missing observability.jsonl is explicit; turns.jsonl access was denied. Therefore backlog health and scheduled-worker configuration cannot be independently proved.
2. **Scheduled-worker risk persists.** Repeated historical notices and the current open action identify kimi-for-coding/k2p6 as obsolete. Do not declare repair complete merely because this synthesis report exists or because the main session is healthy.
3. **No curation proposal.** The last user signal is a transient status update about preparing a Google interview talk and was already ignored by the curator. No durable memory proposal is warranted.
4. **Stale operational state is itself material.** decision-state.json remains dated 2026-05-27 and the open notices retain older generated-model identity and cleanup tasks. This cycle should not be classified as a pure no-op.
• Main agent/infrastructure: inspect scheduled-worker source/config, replace obsolete model selection, then verify two consecutive scheduled successes through the control plane.
• Main agent/infrastructure: obtain `persistent_chat_log_backlog_status`, timer/subagent status, and observability records when permissions/tools return; never use raw canonical-vs-model line counts as backlog evidence.
• Main agent/curator: refresh `decision-state.json` and fix generated model identity at its source; do not edit generated summaries directly.
• Infrastructure: harden notice regeneration to exclude resolved/obsolete reports and add atomic/rollback-safe writes for curated-memory metadata updates (the July truncation incident remains an unresolved risk).
• Matrix-lite timer/subagent status tools were not available through the provided tool surface.
• Native read of `/home/matrix-lite/state/turns.jsonl` was denied.
• `/home/matrix-lite/state/persistent-chat/observability.jsonl` was not found.
• No approvals were requested; no subagents were used.
• No curated-memory edit or proposal.
• Warm memory updated only with this cycle's operational summary in `recent-topics.md`; no new user topic was added.
The main session can appear healthy while the scheduled synthesis worker remains misconfigured and while generated/notice state drifts. A single control-plane health surface that reports worker model, last result, backlog status, timer state, and source freshness would materially reduce this blind spot.
