Runtime memory restore is healthy, but the latest model-heartbeat is degraded: ACP completed without the required sentinel and recorded deterministic fallback NO_CHANGE. The semantic state changed, so this is not a clean no-op. No direct user activity is present after 2026-08-17; the preferred model log ends with Google interview-talk preparation.
• `memory-heartbeat.json` at 04:07Z: restore `ok=true`, 7,476 entries, `semantic_changed=true`.
• `model-heartbeat.json` at 03:47Z: `rc=0`, `acpx_rc=0`, but `outcome=degraded`, `action=fallback-no-change`, because the model turn ended without sentinel. Curated memory was not changed; reflection journal was touched.
• Direct ACP context is normal at 184,658 provider tokens (17.6%), with no reload recommended; configured model is `openai/gpt-5.6-terra`.
• Model conversation log has 6,342 filtered rows and latest direct user turn at 2026-08-17T16:13:27Z. This does not imply missing conversations; canonical/model logs are intentionally filtered/deduplicated.
• Open maintenance remains material: scheduled-worker repair still cites obsolete `kimi-for-coding/k2p6`; decision-state and generated model identity are stale; provider-ceiling/control-plane verification and notice-source hardening remain unverified/open.
• The current heartbeat issue is likely completion-contract/sentinel handling rather than an ACP transport failure, because ACP returned zero and deterministic fallback wrote state. Verify the next two heartbeat runs and inspect sentinel validation if degradation repeats.
• `semantic_changed=true` with no curated-memory change may be candidate/semantic housekeeping rather than durable user signal; do not promote anything without curator review.
1. Repair the scheduled worker’s model/config selection and prove two consecutive successful runs; do not accept NO_CHANGE fallback as healthy.
2. Review provider ceiling, timer/subagent status, and turns.jsonl/observability/backlog status when control-plane access is available. Do not infer backlog from line counts.
3. Fix generated-state source for stale model identity and refresh decision-state.json; do not edit generated summaries directly.
4. Preserve housing safety boundary: authenticated session first, draft-only external replies unless the user confirms.
recent-topics.md was prepended with this cycle’s runtime status and open risks. No curated-memory proposal is warranted from the quiet user interval.
• Timer/subagent status tools were not available through the provided tool surface.
• `turns.jsonl`, `observability.jsonl`, and `persistent_chat_log_backlog_status` were not independently verified here. These are verification gaps, not evidence of backlog.
• No approvals were requested; no subagents were spawned.
The heartbeat can appear successful (rc=0) while silently falling back when its sentinel contract fails. The wrapper should distinguish transport success, model completion, sentinel validity, and durable-file change as separate health dimensions, and alert on repeated degraded fallbacks.
