Executive state

Runtime healthy: memory-heartbeat.json at 16:09Z reports restore ok=true, 7,476 entries, and semantic_changed=true. model-heartbeat.json reports the latest curator run successful (rc=0, acpx_rc=0, NO_CHANGE) at 15:50Z.
Direct ACP healthy and below pressure: context-guard.json is normal, 184,658 provider tokens / 17.6%, no compaction, on openai/gpt-5.6-terra; no reload is recommended.
No newer user conversation: model-conversation-log.jsonl ends at 2026-08-17T16:13:41Z. The durable latest context remains the user's Google interview-talk preparation and temporary absence.
Material backlog remains: the scheduled-worker model/config repair is still open and continues to cite obsolete kimi-for-coding/k2p6; generated continuity-summary.txt also still claims that model despite live GPT-5.6 Terra.

Findings

Scheduled-worker health is not proven. The healthy model heartbeat is a separate path and does not validate operational-synthesis worker selection. The open 2026-08-17 action should remain high priority until source/config inspection and two consecutive verified scheduled successes.
Candidate lifecycle is uneven. semantic-candidates.jsonl has reviewed statuses through 2026-08-17 and no visible current open semantic candidate. memory-candidates.jsonl still contains roughly eleven late-July/early-August records with status=candidate (including housing workflow, income, archive, and compaction items). They are review material, not facts; the model curator should process them in a bounded batch.
Source/generated drift persists. continuity-summary.txt is generated and must not be edited directly. Fix the model identity source/helper, then regenerate. decision-state.json is stale since 2026-05-27 and still omits several later resolved/open threads.
Canonical log interpretation is healthy. The preferred model log is explicitly filtered/deduplicated (6,342 rows; 3,664 runtime-turn rows). No backlog conclusion is drawn from its difference from the canonical log. The 2026-08-17 user turn is present and the memory restore reports no missing runtime entries in its available metadata.

Actions / recommendations

Repair scheduled-worker model selection and verify two consecutive scheduled successes; do not infer this from model-heartbeat success.
Have the curator review the remaining memory-candidates.jsonl candidate-status rows using the deterministic lifecycle helper; do not promote them from this worker.
Refresh decision-state.json and repair the generator for continuity-summary.txt when a main-agent/curator source-edit turn is available.
Preserve the existing user follow-ups: ImmoScout inbox retry is authenticate-first, draft-only, and confirmation-gated; YouTube archive continuation is local/user-driven (40/55 remained after server cookie rotation).

Hypotheses

The recurring stale k2p6 worker failures are most likely a separate hardcoded/configured worker path, not a current direct-ACP provider outage. This remains unverified until the worker source/config and live timer path are inspected.
The absence of post-2026-08-17 user turns is likely intentional (interview preparation), not evidence of missing conversation data; current model log and memory metadata agree on the latest activity.

Blockers and missing checks

Matrix-lite timer/subagent status tools were not exposed through the available tool surface this cycle.
Independent reads of /home/matrix-lite/state/turns.jsonl, observability.jsonl, and workspace timers were not performed/available here. Do not infer timer, subagent, or backlog state from that absence or from line counts.
No native or async subagent was used; no approvals were requested.

Memory boundaries

No edit to curated-memory.md, semantic-memory.json, or canonical logs.
No curated-memory proposal was necessary beyond the existing pending candidate-review action; the Google-talk status is transient and already represented in curated context.
Warm memory was updated in recent-topics.md with this cycle's runtime/backlog summary.

Robustness risks

High: scheduled worker can remain silently broken while the main heartbeat appears healthy. Derive worker model from live config and add an unattended smoke check.
Medium: generated identity drift can mislead recovery/curation prompts. Add source-of-truth validation during packet generation.
Medium: recurring directed-index notice re-inflation and the known curated-memory truncation incident remain open hardening concerns; prefer atomic writes, pre/post size checks, and source-level deduplication.
