Operational Synthesis — 2026-09-07T10:11:11Z

Status

• Memory heartbeat is healthy at 2026-09-07T10:09:37Z: restore ok=true, 7,528 source entries, 6,487 visible entries, and missing_runtime_entries/needs_sync were not reported as problematic.
• Model heartbeat is healthy at 2026-09-07T10:06:14Z: rc=0, acpx_rc=0, outcome success, marker NO_CHANGE.
• Preferred model conversation log is current through 2026-09-05T10:13:16Z (6,394 rows). The latest user thread was Hamburg/Ghost Town followed by a 5–15 minute walk search for counter-service coffee and food near Hauptbahnhof. This is transient travel context and should be re-verified live before reuse.
• Semantic memory changed during the latest memory heartbeat, but no new durable user fact is evident from the available recent conversation tail. Do not promote the Hamburg recommendations into curated memory.

Material findings

1. Runtime continuity is currently healthy, but independent control-plane verification remains unavailable. The scheduled status/timer/subagent/observability surfaces were not exposed in this worker, so timer execution, subagent backlog, and provider ceiling remain unverified. The memory heartbeat's source counts must not be compared as a raw canonical-vs-filtered backlog signal.
2. The long-standing scheduled-worker model drift remains unresolved. Recent operational notes and open action 2026-08-17 still identify generated continuity state claiming obsolete kimi-for-coding/k2p6, while the live/main context has been openai/gpt-5.6-terra. Current heartbeat success does not prove the worker source/configuration is repaired; require source repair plus two clean runs.
3. Open maintenance work is still material despite no new user turn: stale decision-state.json (last updated 2026-05-27), semantic-memory quality audit, directed-index notice re-inflation hardening, provider-ceiling proof, and the isolated durable polling-control-plane design remain open. The polling design should stay before the native backend, with shadow mode and a narrow ACP-resume adapter first.
4. Notice hygiene remains fragile. notices.jsonl contains 56 historical rows and the current actionable rows still include stale/duplicate-prone items. Do not rewrite history from this worker; the helper should filter resolved/obsolete directed reports before repopulation.

Hypotheses / interpretation

• The successful heartbeat likely reflects the current worker path being usable, not resolution of the obsolete-model source drift; this should be treated as unproven until the worker configuration is inspected and two consecutive runs are verified.
• semantic_changed=true with model heartbeat NO_CHANGE may reflect candidate/semantic maintenance rather than a curated-memory promotion. Curator-owned lifecycle review is required before treating any candidate as fact.

Actions for main agent / infrastructure

• Repair scheduled-worker model selection at the source/configuration layer; then verify two consecutive scheduled runs and refresh generated packets through the normal helper.
• Expose or authorize read-only control-plane diagnostics for timers, subagents, turns/backlog, observability, and provider ceiling; record explicit missing_runtime_entries/needs_sync rather than inferring from line counts.
• Stage the isolated polling control plane as a separate service/state/queue in shadow mode. Preserve arbitrary per-watch schedules, retries/backoff, deadlines, dedupe/debounce, wake budgets, and visible subagent lifecycle; do not extend the ACP-coupled legacy timer dispatcher.
• Have the curator review semantic candidates and audit low-signal entries in semantic-memory.json; this worker makes no direct curated-memory edit.

Curated-memory proposal

None. The latest Hamburg travel and food recommendations are transient, and no new durable preference or commitment is supported by the current evidence.

Blockers / missing tools

• Matrix-lite timer/subagent status tools were not available in the exposed tool surface.
• Direct reads of turns, timers, approvals, observability, and worker source/configuration were not independently verified in this cycle. No approvals were requested.
• No native or async subagent was spawned; exploration was limited to read-only state artifacts.

Operational risk

The main risk is false confidence from a green heartbeat while scheduled-worker model drift and control-plane visibility remain unproven. A second risk is notice-source re-inflation, which can bury genuinely actionable blockers under repeated obsolete entries. Keep generated summaries source-driven and add atomic/backup-safe writes for durable memory files.
