• **status**: completed
• **material_digest**: 8a88cfad7f18f30db96a14e8824e9b5e522579719141c58b978fb26a60908df8
• **focus**: scheduled full synthesis
• **Scheduled synthesis recovered**: This is the first successful scheduled synthesis since 2026-06-18T16:11Z. Every 22:11Z and 04:11Z run from 2026-06-18T22:11Z through 2026-06-23T04:11Z failed with `OpenCode ACP prompt returned end_turn with no assistant text and zero usage`, then SIGTERM. The main persistent-chat session and model heartbeat were unaffected.
• **User activity unchanged since 2026-06-18T08:23:52Z**: The last user message (2026-06-18T07:53:16Z) chose listing **168589262** (Unterschleißheim) and corrected the salutation format. The assistant turn at 08:23:52Z was interrupted by direct-ACP runtime while beginning to apply to #1; send status is **unconfirmed**.
• **Heartbeat and context healthy**: Model heartbeat 08:15:51Z succeeded (`rc=0`, `acpx_rc=0`, `marker=UPDATED`), and curated memory was updated at 08:14:25Z. Context-guard is `stage=normal`, ~46.6% of 1.05M tokens, no reload since 2026-05-29T20:43Z.
• `model-conversation-log.jsonl` lines 5520–5582 and `perpetual-log.jsonl` lines 6660–6717 (latest user/assistant turns and direct-ACP interrupt marker).
• `memory-heartbeat.json`, `model-heartbeat.json`, `context-guard.json`, `pinned-state.md`, `session-packet.md`, `memory-context-manifest.json`.
• `operational-synthesis/{actions,findings,hypotheses,notices}.jsonl`, `latest.md`, `directed/index.json`.
• `curated-memory.md` tail (salutation directive confirmed promoted), `recent-topics.md`, `curator-journal.md` head/tail, `semantic-candidates.jsonl` tail.
1. **Synthesis failure cascade resolved (this turn)** — notices.jsonl entries 14–31 document nine consecutive blocked runs with the same zero-usage end_turn + SIGTERM signature. The current 10:11Z run produced normal output.
2. **Open ImmoScout action: listing 168589262 send status unknown** — The assistant partial response at 2026-06-18T08:23:52Z begins "I’m applying to #1 = 168589262 now" but carries a direct-ACP interrupt warning. No later log lines confirm inbox/captcha/submit state.
3. **Heartbeat/curation is healthy** — model-heartbeat.json 2026-06-23T08:15:51Z: rc=0, acpx_rc=0, marker=UPDATED, curated_changed=true, reflection_changed=true. The salutation-format correction from 2026-06-18 is already present in curated-memory.md (line 204).
4. **Session context stable** — context-guard.json: stage=normal, metric=488814 (46.6%), session_turn_count=384, context_epoch_turn_count=98, last provider compaction 2026-06-11. No reload since 2026-05-29T20:43Z.
5. **Model identity mismatch still open** — continuity-summary.txt line 4 declares Current model: kimi-for-coding/k2p6, while context-guard.json configured_model_context.model is openai/gpt-5.4. The system prompt injected into this session also declares kimi-for-coding/k2p6.
6. **Maintenance backlogs unchanged** — decision-state.json last updated 2026-05-27; semantic-memory.json still contains prompt-fragment garbage entries; notices.jsonl had accumulated 31 entries, many obsolete.
7. **Candidate backlogs remain cleared** — Grep found zero "status": "candidate" or "needs_more_evidence" entries in memory-candidates.jsonl and semantic-candidates.jsonl.
| # | Action | Owner | Status |
|---|--------|-------|--------|
| 1 | Monitor next 22:11Z synthesis cycle to confirm the failure cascade is over | operational_synthesis | monitoring |
| 2 | Verify interrupted ImmoScout application to **168589262** (check inbox / captcha / send state) | main_agent | open |
| 3 | Compact notices.jsonl by removing obsolete context-guard and resolved synthesis entries | operational_synthesis | done this turn |
| 4 | Refresh decision-state.json (stale since 2026-05-27) | main_agent | open |
| 5 | Audit/clean semantic-memory.json garbage entries | main_agent / curator | open |
| 6 | Fix source of model identity mismatch (continuity-summary.txt / session-packet generator) | main_agent / infrastructure | open |
• **Synthesis failures are provider/runtime transient** — Same signature as the 2026-06-13–06-16 cascade. Recovery without code changes supports this. Confirm by observing the next 1–2 cycles.
• **The 2026-06-18T08:23:52Z direct-ACP interrupt is the same runtime class** that killed synthesis runs; it left a user-facing action dangling because there is no automatic resume artifact.
• `bash` is denied entirely in this worker route.
• `matrix_lite_status_*` native tools are not exposed in the current tool set.
• Read access to `/home/matrix-lite/state/turns.jsonl`, `/home/matrix-lite/state/observability.jsonl`, `/home/matrix-lite/state/approvals.json`, and `/home/matrix-lite/workspace/state/timers/timers.json` is denied by `external_directory` policy (consistent with previous cycles).
• **Background-agent reliability**: The synthesis route has now failed twice in multi-run cascades (2026-06-13–16 and 2026-06-18–23). Consider writing a checkpoint stub to the report path *before* invoking the model so a failed run still leaves an artifact instead of a stale pre-created checkpoint.
• **Interrupted action tracking**: The Unterschleißheim 168589262 application shows that a direct-ACP interrupt can leave an action half-started. A small pending-action artifact (e.g., `pending-actions.jsonl`) consumed by the main session on its next turn would reduce dropped tasks.
• **Model identity drift**: The mismatch between configured model (`openai/gpt-5.4`) and injected prompt model (`kimi-for-coding/k2p6`) risks wrong capability/context assumptions. Root cause likely lies in the prompt builder reading a stale character/model source; worth a targeted fix.
