Summary

Material change since 04:11Z: persistent-chat main model completed a Kimi cutover this morning (2026-06-25 07:49Z–09:40Z). After several reload attempts, the live session is now persistent-chat-20260625T093941Z (ses_101d95fd6ffeo4VYHq85aW1s3y) on kimi-for-coding/k2p7 with a 262K context limit. This resolves the long-standing model identity mismatch.

Two early Matrix-lite direct-ACP test turns (Test test at 08:04Z and 08:55Z) failed with the generic no-final-answer message, but native ACPX stream test prompts at 09:04Z and 09:45Z succeeded (TEST_OK, KIMI_TEST_OK). No new durable user messages have arrived since 2026-06-18T07:53:16Z.

Heartbeats are healthy, candidate backlogs remain clear, and context pressure is reset to normal after the reload.

Findings

🟢 Kimi cutover completed

• Reload sequence:

- 07:49Z — persistent-chat -> persistent-chat-20260625T074841Z (ok=False, dual-summary handoff)

- 07:56Z — retry, ok=True (persistent-chat-20260625T075516Z)

- 08:11Z — service-restart attempt, ok=False (persistent-chat-20260625T081030Z)

- 08:13Z — fresh session while daemon running, ok=True (persistent-chat-20260625T081252Z)

- 09:40Z — final after fixing launcher env var, ok=True (persistent-chat-20260625T093941Z)

• context-guard.json now reports:

- configured_model_context.model: kimi-for-coding/k2p7

- max_context: 262144

- stage: normal, metric: 0 (fresh session)

• The system prompt / continuity-summary claim of Kimi K2.6 is now consistent with the serving backend.

🟡 Direct-ACP Matrix turns unstable immediately after cutover

• Test test at 08:04Z and 08:55Z both returned:

> "Matrix-lite did not receive a final answer for this request. The direct ACP model/tool run failed or was interrupted..."

• Native ACPX stream prompts at 09:04Z (Reply only: TEST_OK) and 09:45Z (Reply only: KIMI_TEST_OK) succeeded.
• Hypothesis: the Kimi backend initially failed to produce a final answer inside the Matrix-lite direct-ACP wrapper, while the raw ACPX stream path worked. The 09:40Z final reload may have stabilized this, but no Matrix direct-ACP user turn has been attempted since.

🟢 No new durable user activity

• Last meaningful user message remains 2026-06-18T07:53:16Z (salutation-format correction + choice of ImmoScout listing 168589262).
• The assistant turn at 08:23:52Z was interrupted by direct-ACP runtime; send status of application to 168589262 is still unverified.
• Post-cutover traffic is limited to test prompts.

🟢 Heartbeat and context health

• Latest model-heartbeat.json (08:20:52Z): rc=0, acpx_rc=0, action=no-change, marker=NO_CHANGE.
• Latest memory-heartbeat.json (10:10:55Z): 6733 canonical entries, 5594 model-conversation rows, missing_runtime_entries=0, needs_sync=false.
• semantic_changed=true in memory-heartbeat; no open candidate backlog flagged.

🔴 notices.jsonl stale duplicates regenerated again

• Five auto-generated duplicate entries appended at 2026-06-25T04:16:53Z (entries 8–12), coinciding with directed/index.json update.
• These duplicate old action/finding items from reports dated 2026-06-05, 2026-06-16, and 2026-06-23.
• This is the fourth consecutive cycle observing this helper behavior. Cleaned in this report.

Actions

| # | Action | Owner | Status |

|---|--------|-------|--------|

| 1 | Mark Kimi-cutover reload actions resolved (final 09:40Z reload ok=True) | operational_synthesis | resolved this turn |

| 2 | Clean stale notices.jsonl duplicates regenerated at 04:16:53Z | operational_synthesis | resolved this turn |

| 3 | Monitor next 1–2 Matrix direct-ACP user turns for stability on Kimi backend | main_agent / operational_synthesis | monitoring |

| 4 | Verify interrupted ImmoScout application to Unterschleißheim 168589262 | main_agent | still open |

| 5 | Refresh decision-state.json (stale since May 27) | assistant | still open |

| 6 | Audit and clean semantic-memory.json garbage entries | assistant_or_curator | still open |

Blockers / Missing Tools

• matrix_lite_status_timer_list/get/subagent_list/status/log tools still not exposed in the current function set.
• Read access 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. Core file-based synthesis was sufficient this turn.
• Bash is available for non-mutating diagnostics but was not needed.

Backlog Plan

• Next scheduled cycle (16:11Z): confirm no new user messages; check whether any Matrix direct-ACP turn has succeeded on the Kimi backend; verify notices.jsonl has not been repopulated with stale duplicates; monitor heartbeat.
• Main agent: on next user turn, explicitly verify Matrix direct-ACP reply delivery on Kimi; if 168589262 is still pending, confirm send state.
• Infrastructure: identify the automated helper that repopulates notices.jsonl from old reports and stop it, or make it idempotent.

Notes for Future Cycles

• The model identity mismatch finding/action can be considered resolved, but the exact model string should be kept consistent (k2p6 in prompts vs k2p7 in context-guard). This is now a minor cosmetic item rather than a mismatch.
• Context pressure is effectively reset after the Kimi reload; monitor for accumulation over the next 24–48h.
