Executive summary

Runtime and memory restoration are healthy, but maintenance is not no-op: the scheduled-worker model selection remains unverified and generated continuity state still advertises obsolete kimi-for-coding/k2p6. The preferred model log has no user turn after 2026-08-17; the last durable user context is preparation for a Google interview talk.

Evidence

• memory-heartbeat.json 04:10Z: restore ok=true, 7,476 entries; model-conversation log 6,342 rows / 3,664 runtime rows; semantic state changed.
• model-heartbeat.json 03:51Z: rc=0, acpx_rc=0, NO_CHANGE; no curated-memory or reflection change.
• context-guard.json 04:09Z: direct ACP normal, 184,658 provider tokens (17.6%), no compaction, live/configured model openai/gpt-5.6-terra.
• model-conversation-log.jsonl ends 2026-08-17T16:13:41Z: user is away preparing the Google interview talk. This is verified from the preferred model log, not inferred from line-count differences.
• semantic-memory.json remains broad/low-quality in places (old prompt fragments); semantic candidates are review material and no promotion is proposed.

Findings and hypotheses

1. Healthy main path, stale generated identity (high confidence). Live context/pinned state say GPT-5.6 Terra, while continuity-summary.txt line 4 says kimi-for-coding/k2p6. This is source/generator drift, not a live-model failure.
2. Scheduled worker remains at risk (high confidence). Open action and notice from 2026-08-17 still require replacing the obsolete worker model and proving two consecutive scheduled successes. No control-plane evidence was available this cycle to close it.
3. Operational state is stale beyond model identity. decision-state.json last changed 2026-05-27; pinned fresh notices still contain old 2026-08-13/08-14 failures. Existing cleanup/hardening actions remain relevant.
4. No new curation proposal. The Aug-17 Google-talk context is already represented in current continuity state; do not promote transient activity or stale candidate records.

Open actions / recommended next checks

• Repair scheduled-worker source/config to use an available current model; verify two consecutive unattended scheduled runs and update the 2026-08-17 action only after proof.
• Repair the generator/source of continuity-summary.txt; do not edit generated output directly.
• Verify provider ceiling and independent timer/subagent/backlog status when control-plane surfaces return. Do not infer backlog from canonical/model log count differences.
• Refresh decision-state.json, prune obsolete notices, and audit semantic-memory garbage through the owning curator/main-agent workflow.
• Housing inbox retry remains confirmation-gated/authenticate-first; YouTube archive continuation remains local/user-driven. These are old open tasks, not current user requests.

Missing tools / blockers

• /home/matrix-lite/state/turns.jsonl read was denied by policy.
• observability.jsonl is absent.
• Timer/subagent status tools were not exposed in the available tool surface; timers and active jobs therefore could not be independently verified.
• No approvals requested; no subagents spawned. No files outside operational-synthesis/recent-topics were modified.

Risk / robustness note

The recurring split between live model identity and generated continuity output can misroute future maintenance workers. Add a single authoritative model-identity source plus a freshness/consistency check that fails closed (or emits a prominent notice) when generated packets disagree with context-guard.json.
