Summary

Runtime memory processing is healthy, but scheduled-worker/config drift remains unresolved. The preferred model log has no user activity after 2026-08-17; the latest durable context is Google interview-talk preparation. This is material because the checkpoint was the only report for this cycle and the worker repair has still not been verified.

Findings

• Memory heartbeat completed at 10:10Z with entries=7476, restore ok=true, and semantic_changed=true; model-conversation-log is 6,342 rows (3,664 runtime-turn rows). No curated-memory promotion is indicated by the latest model heartbeat (rc=0, acpx_rc=0, NO_CHANGE).
• Direct ACP context is normal: 184,658 provider tokens / 17.6%, backend session persistent-chat-20260805T100658Z, no provider compaction, and no reload recommendation.
• continuity-summary.txt was regenerated at 10:10Z but still claims obsolete kimi-for-coding/k2p6; live context guard identifies openai/gpt-5.6-terra. This is generated-state drift, not evidence that the live backend changed.
• The open scheduled-worker repair action from 2026-08-17 remains the current high-priority operational item. No Aug 24–28 completed synthesis report is present beyond this checkpoint, so two consecutive repaired worker runs cannot be claimed.
• decision-state.json remains stale (updated=2026-05-27). Existing actions remain open for decision-state refresh, semantic-memory cleanup, provider-ceiling/control-plane verification, RAG/anchor retrieval, provider-switch handoff, and local YouTube archive follow-up.
• Historical semantic candidates are explicitly stale/review material; no candidate is promoted or treated as fact by this cycle. No new durable user preference requires a curation proposal.

Hypotheses

• Most likely explanation for the report gap and repeated obsolete-model failures is a stale scheduled-worker model/config source rather than main-session health. Confirm by source/config inspection and two successive scheduled runs after repair.
• Generated model identity will continue to drift until its generator/source is corrected; editing continuity-summary.txt directly would be non-durable.

Actions for main agent/infrastructure

1. Inspect and repair the scheduled synthesis worker’s model selection; remove kimi-for-coding/k2p6 from the source/config, then verify two consecutive successful scheduled runs.
2. Refresh decision-state.json when a normal main-agent/curator edit is available.
3. Fix the continuity-summary generator/source and independently verify the resulting model identity.
4. Keep ImmoScout inbox follow-up confirmation-gated and authenticate-first; the last relevant request failed on 2026-08-13. YouTube archive is user-driven/local after repeated VPS cookie invalidation.

Blockers and missing checks

• Native reads of /home/matrix-lite/state/turns.jsonl, observability.jsonl, approvals.json, and workspace timers were denied by the external-directory policy in this cycle.
• Matrix-lite timer/subagent/log-backlog status tools were not exposed in the available tool set; timer state, subagent state, missing_runtime_entries, and needs_sync were not independently verified.
• No subagents were spawned; no approvals were requested.

Operational risk

The main chat is healthy, but background synthesis can silently fail or remain unreported when its worker invokes a removed model. Add a worker health surface reporting selected model, exit code, report-path validation, and last-success age independently of the model-generated report.
