• status: completed
• focus: scheduled full synthesis
• material_digest: 4caf1325b3ba4880a02b9a1319850d56c6bf2e9f921274a58b98ea1fa95634b3

Summary

Quiet, healthy cycle. No new user activity. The 9-run scheduled-synthesis failure cascade (2026-06-18T22:11Z through 2026-06-23T04:11Z) is now considered resolved after three consecutive successful runs (2026-06-23 10:11Z, 22:11Z, and this 2026-06-24 04:11Z turn). Heartbeat, context pressure, and log sync all remain healthy. The only material work is the usual maintenance backlog.

Evidence Reviewed

• model-conversation-log.jsonl (5582 lines, unchanged since 2026-06-23T22:11Z synthesis)
• memory-heartbeat.json (2026-06-24T04:08:04Z; entries=6717, semantic_changed=true)
• model-heartbeat.json (2026-06-24T02:19:54Z; rc=0, acpx_rc=0, marker=UPDATED, curated_changed=true, reflection_changed=true)
• context-guard.json (2026-06-24T04:12:54Z; stage=normal, metric=488,814 / 46.6%, session_turn_count=384)
• curator-journal.md tail (no new durable promotions since prior cycle)
• curator-log.jsonl tail (healthy UPDATED runs)
• operational-synthesis/actions.jsonl, findings.jsonl, hypotheses.jsonl, notices.jsonl
• decision-state.json (still stale since 2026-05-27)
• semantic-memory.json (still contains prompt-packet garbage entry at line 306)
• continuity-summary.txt (still declares model kimi-for-coding/k2p6 despite configured openai/gpt-5.4)
• recent-topics.md (previous cycle 2026-06-23T22:11Z)
• semantic-candidates.jsonl (0 open candidates; all visible entries stale)
• memory-candidates.jsonl (0 open review backlog)

Findings

• 🟢 No new user messages: Last user message remains 2026-06-18T07:53:16Z. ~5.8 days quiet.
• 🟢 Synthesis failure cascade resolved: Previous run (2026-06-23T22:11Z) and current run both produced normal output. Combined with 2026-06-23T10:11Z, that is three consecutive successes after the 9-run cascade of zero-usage end_turn + SIGTERM failures. Root cause remains best explained as provider/runtime transient; no code changes were required for recovery.
• 🟢 Heartbeat healthy: Latest model-heartbeat 2026-06-24T02:19:54Z: rc=0, acpx_rc=0, marker=UPDATED, curated_changed=true, reflection_changed=true.
• 🟢 Context pressure normal: context-guard 2026-06-24T04:12:54Z: stage=normal, metric=488,814 (~46.6%), session_turn_count=384, no reload since 2026-05-29T20:43Z.
• 🟢 Log sync healthy: canonical 6717 lines, model-conversation 5582 lines, missing_runtime_entries=0, needs_sync=false.
• 🟢 Candidate backlogs cleared: 0 open memory candidates, 0 open semantic candidates.
• 🔴 Maintenance backlog still open:

- decision-state.json refresh (stale since 2026-05-27)

- semantic-memory.json garbage entry at line 306 (system-prompt packet fragment)

- Model identity mismatch: continuity-summary.txt and system prompt declare kimi-for-coding/k2p6; configured/serving model is openai/gpt-5.4

- Verify interrupted ImmoScout application to Unterschleißheim listing 168589262 (assistant turn interrupted by direct-ACP runtime at 2026-06-18T08:23:52Z)

• 🟡 Tool restrictions this turn: Read denied for /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 due to external_directory policy. bash denied entirely. Native matrix_lite_status_* tools are not exposed in the current tool set. Core file-based synthesis was sufficient.

Actions

• Mark the 2026-06-18T22:11Z–2026-06-23T04:11Z synthesis failure cascade as resolved.
• Continue monitoring next 1–2 synthesis cycles for stability.
• When user returns, verify ImmoScout 168589262 send/captcha state before any new outreach.
• Refresh decision-state.json with current resolved/open threads.
• Audit and remove the prompt-packet garbage entry in semantic-memory.json line 306.
• Fix model identity source so continuity-summary.txt and system prompt match configured model (openai/gpt-5.4).

Hypotheses

• None new. Prior hypothesis that the synthesis cascade was a provider/runtime transient continues to hold; sustained success without code changes supports it.

Blockers / Missing Tools

• bash denied entirely in this synthesis route.
• Read access denied for /home/matrix-lite/state/*.jsonl and /home/matrix-lite/workspace/state/timers/* under external_directory policy.
• Native matrix_lite_status_timer_list, matrix_lite_status_subagent_list, etc. are not exposed in the synthesis worker tool set.
• These restrictions are non-fatal for file-based synthesis but prevent live timer/subagent/approval diagnostics.

Matrix-lite Operational Risks / Suggested Robustness Fixes

1. Synthesis-route reliability: While the cascade resolved, the root cause (zero-usage end_turn + SIGTERM) was never pinpointed. Consider adding lightweight per-run telemetry (model/provider/backend id, exact failure timestamp, route label) so future cascades can be correlated with provider events.
2. Model identity drift: The continuity summary and system prompt still claim the wrong model. This is cosmetic until a reload occurs, but it could confuse the curator, subagents, or user. Align the prompt builder with context-guard.configured_model_context.
3. Stale decision state: decision-state.json has not been refreshed in ~4 weeks. Several threads (truncation fix, native backend migration, ImmoScout workflow, tarot, research anchors, WOLTE) are resolved or changed. A refresh would reduce stale guidance in heartbeat/context packets.
4. Semantic memory garbage: The line-306 system-prompt fragment continues to be injected into semantic memory. It should be removed to prevent it from surfacing in search results.
