Summary

Memory/runtime maintenance is healthy, but the operational backlog is still material. The preferred model conversation log is current through 2026-09-05 10:13Z, with the latest user thread being Hamburg coffee/food near Hauptbahnhof. The durable polling/control-plane design remains the main engineering action.

Evidence Reviewed

• `memory-heartbeat.json`: 7,528 entries, restore `ok=true`, no generated-state changes.

• `model-heartbeat.json`: latest run `rc=0`, `acpx_rc=0`, `NO_CHANGE`; no current heartbeat failure.

• `model-conversation-log.jsonl`: 6,394 rows, current through 2026-09-05; latest user refinement allows a 5–15 minute walk from Hamburg Hbf.

• `actions.jsonl`, `notices.jsonl`, `decision-state.json`, semantic-candidate sample, directed index, and prior synthesis reports.

Findings

1. **Runtime healthy:** restore and model heartbeat succeeded. Do not interpret the 7,528 canonical/filtered entries as a sync backlog; no independent missing_runtime_entries/needs_sync check was available this cycle.

2. **Current user context:** Hamburg trip and high-rated counter/self-service coffee/food search remain the most recent durable conversational context. Business hours, ratings, terminal availability, and walking times are transient and must be re-verified live before reuse.

3. **Open architecture work:** the isolated polling control plane action remains open: arbitrary per-watch timing, durable queue, dedupe/debounce, retry/backoff, deadlines, wake budgets, shadow mode, and visible subagent lifecycle. Transitional ACP resume is still distinct from the planned prompt-builder/native backend.

4. **Persistent maintenance debt:** scheduled-worker model/configuration repair is still open; prior generated-state reports repeatedly identify obsolete kimi-for-coding/k2p6. decision-state.json is stale (updated 2026-05-27). Existing notices also retain semantic-memory audit, notice-source hardening, and provider/control-plane verification work.

5. **Candidate lifecycle:** semantic-candidates contains a large historical review pool; this worker did not perform status transitions, consistent with curator ownership. No new high-confidence durable user fact was identified for promotion.

Actions

• Main agent/infrastructure: repair scheduled-worker source/configuration and prove two consecutive clean runs without obsolete model selection.

• Main agent/infrastructure: stage the isolated polling control plane in shadow mode before any ACP dispatch integration; use the existing open action rather than creating a duplicate.

• Main agent/curator: refresh stale `decision-state.json` and audit semantic-memory only through the owning workflow; do not edit generated summaries directly.

Blockers / Missing Checks

• Matrix-lite timer/subagent status tools were not exposed in this worker invocation.

• Reads of `/home/matrix-lite/state/turns.jsonl`, timers, approvals, and observability were not independently verified; `observability.jsonl` has historically been absent.

• No native backlog-status surface was available, so backlog health remains unverified rather than inferred from log counts.

Backlog Plan

• Keep current open notices/actions visible to the main agent; avoid duplicate append records.

• Re-check worker model selection and control-plane status in a future cycle with the native status surface available.

• Re-verify Hamburg recommendations live only when the user resumes that topic.

Curated-memory Proposal

None. The Hamburg outing is useful warm context but transient; no direct edit to curated-memory.md is warranted.

Operational Risk

The largest risk is silent divergence between successful fast/model heartbeats and the still-unrepaired scheduled-worker configuration. A second risk is repeated notice re-inflation from directed-index helpers. Prefer source/configuration fixes and idempotent notice reconciliation over editing generated artifacts.
