Status

Memory heartbeat is healthy (2026-09-07T16:10:57Z, restore ok=true, 7,528 entries; semantic_changed=true).
Model heartbeat returned rc=0/acpx_rc=0, but only via deterministic fallback: no UPDATED/NO_CHANGE sentinel was observed. Treat curator health as degraded, not fully verified.
Preferred model conversation log is stable at 6,394 rows, latest user activity 2026-09-05T10:13:16Z: Hamburg/Ghost Town and a counter-service coffee/food search near Hauptbahnhof. This is transient and must be re-verified live.

Material findings

Curator follow-up backlog is open. The latest curator journal records 13 open memory candidates and 1 semantic candidate; the semantic candidate is needs_more_evidence (a one-off cultural-events request). Review candidates before any promotion. The current semantic change does not establish a new durable user fact.
Scheduled-worker model drift remains unresolved. continuity-summary.txt still says obsolete kimi-for-coding/k2p6, while the active heartbeat context is GPT-5.6 Terra. Green/fallback heartbeats do not prove source configuration repair; require source inspection and two clean runs.
Control-plane verification remains unavailable. Timer, subagent, approval, turns/backlog, observability, and provider-ceiling status surfaces were not exposed to this worker. Do not infer synchronization backlog from canonical/model log count differences.
Persistent engineering backlog remains material: stale decision-state.json (last updated 2026-05-27), semantic-memory quality audit, directed-index notice re-inflation hardening, provider-ceiling/handoff proof, and the isolated durable polling control plane.

Hypotheses

The fallback/no-sentinel result is likely a wrapper or ACP completion-contract issue rather than evidence that memory restore failed; verify the next model-heartbeat outcome.
semantic_changed=true likely reflects candidate lifecycle or metadata maintenance, not a curated-memory promotion; curator-owned status is authoritative.

Actions for main agent / infrastructure

Review the 13 open memory candidates and the one needs_more_evidence semantic candidate in the next model-heartbeat; promote only durable, corroborated signals.
Repair scheduled-worker model selection at source/configuration level and verify two consecutive clean runs.
Expose read-only timer/subagent/turns/backlog/observability/provider-ceiling diagnostics, recording explicit backlog fields.
Stage the polling control plane separately in shadow mode with durable watches, queueing, dedupe/debounce, retries/backoff, deadlines, wake budgets, and lifecycle visibility; keep legacy ACP-coupled timers unchanged.

Curated-memory proposal

None. Hamburg travel recommendations and the latest cultural-events request are transient; no new durable fact is supported.

Blockers / missing tools

Native Matrix-lite timer/subagent status tools were not exposed.
Independent reads of turns, timers, approvals, observability, and worker source/configuration were unavailable in this cycle.
No native or async subagent was spawned; exploration used read-only state artifacts only.

Operational risk

Main risk is false confidence from a nominally green heartbeat when sentinel validation and worker model selection remain unproven. Notice-source re-inflation and non-atomic durable-memory writes remain robustness risks. Keep generated state source-driven and use atomic, backup-safe writes.

# Operational Synthesis — 2026-09-07T16:11:08Z ## Status - Memory heartbeat is healthy (`2026-09-07T16:10:57Z`, restore `ok=true`, 7,528 entries; `semantic_changed=true`). - Model heartbeat returned `rc=0/acpx_rc=0`, but only via deterministic fallback: no `UPDATED`/`NO_CHANGE` sentinel was observed. Treat curator health as degraded, not fully verified. - Preferred model conversation log is stable at 6,394 rows, latest user activity `2026-09-05T10:13:16Z`: Hamburg/Ghost Town and a counter-service coffee/food search near Hauptbahnhof. This is transient and must be re-verified live. ## Material findings 1. **Curator follow-up backlog is open.** The latest curator journal records 13 open memory candidates and 1 semantic candidate; the semantic candidate is `needs_more_evidence` (a one-off cultural-events request). Review candidates before any promotion. The current semantic change does not establish a new durable user fact. 2. **Scheduled-worker model drift remains unresolved.** `continuity-summary.txt` still says obsolete `kimi-for-coding/k2p6`, while the active heartbeat context is GPT-5.6 Terra.
