Operational Synthesis — 2026-09-01T16:11:09Z

Summary

Memory/heartbeat: restore is healthy (ok=true, 7,476 rows); latest model-heartbeat completed successfully (rc=0, acpx_rc=0, NO_CHANGE) and semantic state changed without curated-memory content change.
Conversation activity: preferred model log ends at 2026-08-17T16:13Z, with the latest durable user context being Google interview-talk preparation. This is an observed quiet period, not evidence of missing conversations or backlog.
Persistent drift remains confirmed: generated continuity-summary.txt says kimi-for-coding/k2p6, while recent operational context identifies the live session as openai/gpt-5.6-terra. The successful heartbeat does not prove the scheduled worker is selecting the correct model; source/configuration repair and two clean runs remain required.
Open maintenance backlog remains material: stale decision-state.json (last updated 2026-05-27), semantic-memory quality audit, provider-ceiling proof, independent control-plane visibility, directed notice-source hardening, provider-switch handoff protocol, curated-memory write-safety investigation, housing inbox retry, and local YouTube archive follow-up.

Evidence reviewed

memory-heartbeat.json generated 2026-09-01T16:08Z: restore healthy, 7,476 entries, 6,342 model-log rows, semantic_changed=true.
model-heartbeat.json generated 2026-09-01T15:58Z: rc=0, acpx_rc=0, marker NO_CHANGE; no direct model identity field available.
model-conversation-log.jsonl: latest visible activity is 2026-08-17; recent rows document Google interview-talk preparation and temporary OpenAI-auth recovery.
continuity-summary.txt generated 2026-09-01T16:08Z still contains the obsolete kimi-for-coding/k2p6 identity.
actions.jsonl and notices.jsonl: the model-selection repair remains open, alongside the older runtime/curation actions listed above.
semantic-candidates.jsonl: sampled lifecycle entries are reviewed as stale; they remain review material, not authoritative memory. No new promotion is proposed.

Hypotheses

Scheduled-worker model selection is still stale or its generator is stale (high confidence): repeated generated-summary mismatch plus the open repair action. Confirm by inspecting worker source/config and observing two subsequent clean runs with matching identity.
Control-plane observability is incomplete for this worker (confirmed limitation): direct read of /home/matrix-lite/state/turns.jsonl was denied and observability.jsonl is absent; timer/subagent/backlog status APIs were not exposed in this cycle.

Actions for main agent/infrastructure

Repair the scheduled worker’s model/config source; do not hand-edit generated continuity-summary.txt; then verify two consecutive runs.
When control-plane status is available, check missing_runtime_entries/needs_sync, timers, subagents, and observability independently; never use canonical-vs-model line-count differences as a backlog signal.
Refresh decision-state.json and audit semantic-memory garbage in a dedicated main/curator turn.
Harden directed-index notice regeneration against resolved/obsolete reports; currently notices remain a mix of canonical and historical duplicates.
Preserve the existing no-reload policy: this synthesis found no context-pressure reason to replace the live backend.

Curated-memory proposal

None. The current quiet period and already-reviewed candidate material do not justify a new durable fact. The stale model identity is an operational/generated-state issue, not a memory fact.

Blockers and risks

Missing/denied checks: turns.jsonl read denied; observability.jsonl not found; Matrix-lite timer/subagent/backlog status tools were unavailable to this worker. No approvals were requested.
Operational risk: a successful NO_CHANGE heartbeat can mask an obsolete scheduled-worker model selection; health reporting should expose configured and effective model IDs separately.
Durability risk: prior curated-memory truncation incident and unresolved write-path action remain relevant even though the current file is not being changed.

Worker usage

No native or async subagents used. This was a bounded read-only synthesis followed by this report and warm-memory update.

# Operational Synthesis — 2026-09-01T16:11:09Z ## Summary - **Memory/heartbeat:** restore is healthy (`ok=true`, 7,476 rows); latest model-heartbeat completed successfully (`rc=0`, `acpx_rc=0`, `NO_CHANGE`) and semantic state changed without curated-memory content change. - **Conversation activity:** preferred model log ends at **2026-08-17T16:13Z**, with the latest durable user context being Google interview-talk preparation. This is an observed quiet period, not evidence of missing conversations or backlog. - **Persistent drift remains confirmed:** generated `continuity-summary.txt` says `kimi-for-coding/k2p6`, while recent operational context identifies the live session as `openai/gpt-5.6-terra`.
