Summary

Runtime is healthy, but this is not a no-op: the durable polling/control-plane design remains open, and generated continuity state still has a stale model identity. The preferred model log contains current activity through 2026-09-04; there is no evidence of a conversation-sync backlog.

Evidence

• memory-heartbeat.json at 2026-09-05T04:09:47Z: restore ok=true, 7,522 entries, 3,708 runtime turn rows; semantic state changed.
• model-heartbeat.json at 2026-09-05T04:03:35Z: rc=0, acpx_rc=0, successful NO_CHANGE run.
• model-conversation-log.jsonl: 6,388 rows; latest user activity 2026-09-04T18:38:47Z (Korean chicken sauce) and assistant reply immediately after.
• context-guard.json: direct ACP normal, 266,984 provider tokens / 25.4%, no compaction, no reload recommendation; configured model is openai/gpt-5.6-terra.
• continuity-summary.txt line 4 still incorrectly says kimi-for-coding/k2p6; this is generated-state drift and must be fixed at its source/generator, not by editing the snapshot.
• semantic-candidates.jsonl is review material and the visible sample is already marked stale; no promotion proposal is warranted from this cycle.
• decision-state.json remains stale (last update 2026-05-27) and does not include the later polling-control-plane thread.

Current user context

The user recently attended/planned around the sold-out NCN festival and used Leipzig cultural-event suggestions; the latest exchange was a simple food preference question. Event listings are transient and should be rechecked live before reuse. The durable engineering request is an isolated polling layer before the future sessionless native backend: arbitrary per-watch timing, durable queue, dedupe/debounce, retries/backoff, deadlines, wake budgets, shadow mode, and visible subagent lifecycle. Current ACP-resume dispatch is transitional only.

Findings

1. Memory/restore and model heartbeat are healthy; direct ACP context is comfortably below guard thresholds.
2. The preferred conversation log is current through Sep 4. Do not infer missing conversations from canonical-vs-filtered row counts; explicit backlog status was not available here.
3. The stale kimi-for-coding/k2p6 identity remains unresolved despite repeated successful heartbeats. This is the highest recurring correctness issue in generated continuity context.
4. The polling-control-plane action from 2026-09-02 remains open. A bounded read-only explorer could not inspect /home/matrix-lite/app/** or full state with its tools, so its partial verdict is non-evidence for implementation readiness. It did identify replay/double-fire, due_at/fired_at drift, JSON/lock races, and session auto-creation as risks.

Actions / next checks

• Repair scheduled-worker model/config selection and verify two consecutive clean runs; resolve the existing open action rather than appending a duplicate.
• Before implementation, inspect actual timer/ACP seams and native subagent status through an available control-plane/status surface. Then stage the poller in shadow mode with isolated state, lock, queue, and deterministic event IDs.
• Update decision-state.json in a main-agent/curator turn to capture the current polling architecture and retire stale historical threads.
• Keep generated packets, perpetual-log.jsonl, and curated-memory.md unchanged in this cycle.

Blockers and missing checks

• Native Matrix-lite timer/subagent status tools were not exposed in this worker; pending timers, jobs, approvals, observability, and explicit missing_runtime_entries/needs_sync status could not be independently queried.
• The delegated explorer lacked read access to the app repository and full state, and reached its step limit. No implementation or systemd-wiring claim should be based on that partial inspection.
• No user approval was requested and no live backend/session was replaced.

Risks / robustness suggestions

• Treat stale generated model identity as a context-integrity defect: generation should derive model identity from one authoritative runtime source and fail visibly on disagreement.
• The future poller should use atomic state transitions, durable append/ack semantics, idempotency keys, leases, and explicit outbox delivery; never equate “timer fired” with “agent reply delivered.”
• Expose timer, subagent, queue, and failure state through one read-only status surface so scheduled synthesis can verify health without privileged file access.

Curated-memory proposals

None. Recent user activity is transient and existing durable architecture directives already cover the polling request.
