Operational Synthesis

• completed: 2026-08-26 scheduled cycle
• status: complete (material maintenance required)
• source checkpoint: this report was pre-created at 2026-08-25T22:11:01Z

Summary

Runtime and memory heartbeats are healthy, but the operational state is not clean: the preferred model log has no direct user activity after 2026-08-17, the generated continuity summary still names obsolete kimi-for-coding/k2p6, and the scheduled-worker repair remains unverified. Current direct ACP context is normal at 184,658 provider tokens (17.6%) on openai/gpt-5.6-terra; no reload is indicated.

Evidence Reviewed

• model-conversation-log.jsonl: 6,342 rows; latest direct user/assistant pair is 2026-08-17T16:13Z (Google interview-talk preparation).
• memory-heartbeat.json: 2026-08-25T22:08Z, 7,476 entries, semantic_changed=true, restore ok=true, no row changes in generated notices/actions.
• model-heartbeat.json: 2026-08-25T21:48Z, rc=0, acpx_rc=0, marker NO_CHANGE; curator succeeded without changing curated memory.
• context-guard.json: normal, direct ACP, model openai/gpt-5.6-terra, 184,658 provider tokens, no provider compaction detected.
• actions.jsonl / notices.jsonl: the open scheduled-worker repair still targets obsolete kimi-for-coding/k2p6; other durable maintenance actions include decision-state freshness, semantic-memory cleanup, provider-ceiling proof, RAG, and notice-source hardening.
• semantic-candidates.jsonl: 588 rows, overwhelmingly historical/stale review material; no candidate was promoted by this cycle.
• directed/latest.md: stale metadata (last directed report May 26); directed/index.json was refreshed Aug 25 but contains no newer directed report.

Findings

1. Healthy runtime, stale generated identity. continuity-summary.txt was generated Aug 25 but says Current model: kimi-for-coding/k2p6, contradicting the live context guard and heartbeat. Fix the generator/source, not the generated file.
2. Scheduled synthesis worker remains unproven. The live model heartbeat succeeding does not establish that the separate scheduled worker is configured correctly. The open repair action and historical notices retain the obsolete model. Require source/config inspection plus two consecutive worker successes before resolution.
3. No verified conversation backlog. The model log is intentionally filtered/deduped; no inference is made from canonical-vs-model row counts. turns.jsonl was denied and observability.jsonl is absent, so missing_runtime_entries/needs_sync could not be independently checked this cycle.
4. Semantic memory remains low precision. semantic-memory.json still contains prompt-fragment-like explicit memories. Candidates are review material only; no promotion is proposed.

Hypotheses

• The recurring k2p6 identity is generated-state/source drift, not evidence that the live direct-ACP session switched models.
• Missing control-plane visibility is an access/tooling limitation rather than evidence of a sync backlog; verify through the Matrix-lite status surface when available.

Actions / Proposals

• Main agent/infrastructure: repair scheduled-worker model/config selection and verify two consecutive successful scheduled runs.
• Main agent/infrastructure: trace continuity-summary.txt generation to the live model source and add an identity consistency check.
• Main agent/curator: refresh decision-state.json; audit prompt-fragment semantic memories using the candidate helper workflow, without treating candidates as facts.
• Infrastructure: expose read-only timer/subagent, persistent_chat_log_backlog_status, turns, and observability checks to scheduled workers; add per-worker processing cursors.

Curated-memory proposals

• None. The only current durable user signal is already represented: focus on Google interview-talk preparation and defer other work.

Warm-memory update

• recent-topics.md was updated with this cycle's runtime, stale-worker, model-identity, and verification-gap state.

Blockers / Missing Tools

• Native read of /home/matrix-lite/state/turns.jsonl denied by policy.
• /home/matrix-lite/state/persistent-chat/observability.jsonl not found.
• Matrix-lite timer/subagent status tools were not exposed in the available tool namespace; extended-tool manifest exposed search/browser/vision servers only.
• No approvals requested; no subagents spawned.

Operational risk

The primary robustness risk is silent divergence between live model identity and generated continuity artifacts, compounded by lack of independent scheduled-worker/control-plane telemetry. Add a single authoritative model-identity source and fail/report on mismatch rather than regenerating contradictory packets.
