Summary

Runtime and restore are healthy, but this cycle still has material maintenance work: the generated continuity snapshot names an obsolete model, candidate review remains open, and control-plane health cannot be independently verified from the exposed interfaces. No new user conversation is present after 2026-09-05T10:13:16Z in the preferred model log.

Evidence

• memory-heartbeat.json at 16:08Z: restore ok=true, 7,528 entries, 6,394 model-log rows, semantic_changed=true; no restore occurred.
• model-heartbeat.json at 16:08Z: rc=0, acpx_rc=0, marker NO_CHANGE; no curation content change.
• context-guard.json at 16:07Z: direct ACP on openai/gpt-5.6-terra, 283,998 provider tokens (27.0%), stage normal, no reload recommendation.
• Preferred model log ends at 6,394 rows, latest assistant turn 2026-09-05T10:13:16Z. This is consistent with the heartbeat metadata; canonical/model line-count differences are not interpreted as backlog.
• continuity-summary.txt generated 16:08Z still says kimi-for-coding/k2p6 (line 4), contradicting the live context. Do not edit the generated file directly.
• notices.jsonl has 57 historical rows, including an open scheduled-worker model-repair notice and an open durable-polling-control-plane notice; directed/index reinflation and stale maintenance notices remain historical noise.
• actions.jsonl retains the open high-level polling-control-plane design item and the 2026-09-07 candidate-review item. The latter says 13 open memory candidates and one needs_more_evidence semantic candidate; semantic candidates are review material, not facts.
• decision-state.json is still dated 2026-05-27 and is stale relative to current architecture/runtime decisions.

Findings

1. Healthy runtime, stale generated identity (medium): restore, model heartbeat, and context guard are healthy, but scheduled-worker/source configuration still permits obsolete kimi-for-coding/k2p6 drift. Repair the source/configuration and prove two consecutive clean worker runs.
2. Maintenance backlog is material: candidate review, stale decision state, and isolated durable polling-control-plane design remain open. semantic_changed=true must not be treated as promotion.
3. Current conversation state is quiet but verified: the latest preferred model-log row is 2026-09-05 Hamburg coffee/food context. Do not infer missing turns from canonical-vs-model counts.

Hypotheses

• The continuity-summary mismatch is generated-state/source drift rather than a live-session model switch, because context guard and heartbeat metadata consistently identify GPT-5.6 Terra. Verify by inspecting the scheduled worker/configuration, not by editing output.
• The 13/1 candidate counts may be stale or reflect a curator-owned review queue; exact status distribution needs the curator helper/MCP surface. Do not promote or demote manually from this worker.

Actions for main agent / infrastructure

• Repair scheduled-worker model selection; require two clean runs and confirm line 4 of a newly generated continuity snapshot.
• Review the 13 open memory candidates and one needs_more_evidence semantic candidate through curator helpers; do not modify curated-memory.md here.
• Update stale decision-state.json through the owning workflow.
• Continue isolated durable polling-control-plane design: persistent arbitrary-timing watches, durable event queue, dedupe/debounce, retries/backoff, deadlines, wake budgets, shadow mode, and visible subagent lifecycle before ACP dispatch integration.

Warm memory

• Updated recent-topics.md with this cycle's verified runtime state and open maintenance priorities.
• No curated-memory proposal: no new durable user fact, preference, or correction was found.

Blockers / missing verification

• Matrix-lite timer, subagent, approval, backlog, observability, and provider-ceiling status tools were not exposed in this scheduled worker context. turns.jsonl and related runtime diagnostics were not independently checked here.
• No native or async subagents were used; investigation remained read-only.

Operational risk

The main risk is silent scheduled-worker degradation masked by successful fast/model heartbeat status: generated packets can remain internally inconsistent while the live ACP session is healthy. Add a read-only worker model/config identity check and a durable two-run health assertion to the control plane; also expose timer/subagent/backlog status so synthesis can distinguish healthy quiet from unverified state.
