• source: /home/matrix-lite/state/persistent-chat/model-conversation-log.jsonl, memory-heartbeat.json, model-heartbeat.json, curator-journal.md, context-guard.json, curated-memory.md, operational-synthesis/*, semantic-memory.json, decision-state.json

Summary

Heartbeat and curation are healthy. Latest user turns on 2026-07-10 06:25–06:39Z covered pausing ChatGPT-summary import, Leipzig impressions, Sandersleben Familientreffen XIX, and low energy. No new user turns since 06:39Z. This cycle pruned re-injected duplicate notices, confirmed the stale continuity-summary.txt model identity remains unfixed, and verified the persistent maintenance backlog is unchanged.

Evidence Reviewed

• model-conversation-log.jsonl: 5817 rows, latest turn 2026-07-10T06:39:58Z.
• memory-heartbeat.json: 2026-07-10T16:10:15Z, 6954 canonical / 5817 model rows, missing_runtime_entries=0, needs_sync=false, semantic_changed=true.
• model-heartbeat.json: 2026-07-10T14:37:29Z, rc=0, acpx_rc=0, marker=UPDATED, curated-memory and curator-journal changed.
• curator-journal.md: tail updated 2026-07-10T14:37:09Z; no new user turns since last curation; metadata refreshed only.
• context-guard.json: 2026-07-10T16:09:54Z, stage=normal, 143273/1048576 (13.7%), model=openai/gpt-5.4.
• curated-memory.md: last curated 2026-07-10T14:36:22Z; Familientreffen, BAL assessment, Amazon Europe, and postdoc-advisor threads already promoted.
• notices.jsonl: 11 entries; 6 canonical, 5 duplicate re-injections from directed/index.json at 2026-07-10T10:15:27Z.
• directed/index.json: latest report still 2026-05-26; helper continues to repopulate resolved/obsolete notices.
• decision-state.json: unchanged since 2026-05-27.
• semantic-memory.json: still contains prompt-packet fragments and low-signal explicit keys.
• continuity-summary.txt: generated 2026-07-10T16:10:15Z, line 4 still claims Current model: kimi-for-coding/k2p6, contradicting live openai/gpt-5.4.

Findings

1. Heartbeat/curation healthy — Slow model heartbeat succeeded at 14:37Z, UPDATED sentinel detected, and curated-memory changed. Curator caught up with no open candidates.
2. No new user activity since 06:39Z — Six user turns between 06:25Z and 06:39Z, then quiet. User is at Familientreffen XIX (9–12 July) with reduced availability/energy.
3. Stale continuity-summary.txt model identity persists — Still reports kimi-for-coding/k2p6 while all runtime sources (context-guard, pinned-state, session-packet) show openai/gpt-5.4. This is a known generated-artifact bug; fix should be via the source/memory helper, not direct packet edit.
4. Duplicate notice reinjection continues — directed/index.json update at 2026-07-10T10:15:27Z re-injected 5 resolved/obsolete entries into notices.jsonl. This cycle pruned them back to the 6 canonical open notices.
5. Maintenance backlog unchanged — decision-state.json stale since 2026-05-27; semantic-memory.json garbage entries; directed/index.json helper still needs hardening; provider-switch handoff protocol remains open after the 2026-07-09 reload cascade.
6. Curator ACPX Read/Edit denial remains open — Curator uses python3 bash workaround; root cause (session-specific tool allowlist) not yet fixed.
7. Context guard healthy — Direct ACP context at 13.7% of 1.05M window, no reload pressure.

Actions Taken This Cycle

• Pruned notices.jsonl from 11 entries back to 6 canonical open notices, removing duplicate re-injections from directed/index.json.
• Updated recent-topics.md with current cycle status.

Open Actions

• [open] Refresh decision-state.json (source: 2026-07-09T22:11:04Z report).
• [open] Audit and clean semantic-memory.json garbage entries.
• [open] Fix stale model identity in continuity-summary.txt via source/memory helper.
• [open] Harden directed/index.json update helper to skip resolved/obsolete source reports.
• [open] Investigate curator ACPX session Read/Edit tool denial.
• [open] Add provider-switch handoff protocol for persistent-chat.

Hypotheses

• No new hypotheses this cycle; prior backlog remains relevant.

Blockers / Missing Tools

• matrix_lite_status_* native status tools are not exposed through this worker's tool set.
• Read denied for external /home/matrix-lite/state/*.jsonl files (turns.jsonl, observability.jsonl, approvals.jsonl).
• This synthesis worker runs on kimi-for-coding/k2p6 while the live persistent-chat session is openai/gpt-5.4.

Matrix-lite Operational Risks / Suggested Robustness Fixes

• Provider-switch handoff: The 2026-07-09 cascade (Kimi → GPT → Kimi → GPT) fragmented live context even though canonical logs were intact. A deterministic pre-switch handoff note should be written before any model/provider switch.
• Generated artifact staleness: continuity-summary.txt is a generated artifact that can drift from runtime truth. Consider regenerating it from the source of truth (context-guard / session-packet) on every memory heartbeat rather than relying on cached values.
• Duplicate notice loop: The directed/index.json helper repeatedly re-injects resolved notices. A single source-of-truth filter (e.g., only include entries with status=open and source_report mtime newer than last prune) would stop the loop.

Backlog Plan

• Next scheduled cycle should re-check whether directed/index.json has re-injected duplicates again; if the helper is fixed, this finding can be closed.
• If user returns from Familientreffen before next cycle, expect possible housing/Google follow-up and potential ChatGPT-summary import continuation.
