Operational Synthesis

Summary
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.
Verified findings
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.
Hypotheses
- 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.
Actions for main agent/infrastructure
- Repair the scheduled worker’s model/config selection and prove two consecutive successful runs; do not accept
NO_CHANGE fallback as healthy.
- 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.
- Fix generated-state source for stale model identity and refresh
decision-state.json; do not edit generated summaries directly.
- Preserve housing safety boundary: authenticated session first, draft-only external replies unless the user confirms.
Warm-memory update
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.
Blockers and missing checks
- 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.
Operational risk
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.

## Summary
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.
## Verified findings
- `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.
## Hypotheses
- 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.
## Actions for main agent/infrastructure
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.
