Task: Diagnose in-app Coding session stall

Identity

Diagnose whether the visible Makelore Code run in project 肉鸽小游戏, Agent 小小明, Conversation 新对话 is still doing useful work or is stuck.
Correlate the supplied screenshot with the live Electron/Pi process, Main log, project metadata, and persisted Pi session timeline.
Make no product-code change and do not abort, recover, or otherwise mutate the user's live Conversation.

Treat the screenshot's earlier Token Point failures separately from the latest 继续 turn; do not infer that a historical error is the current terminal cause.
Preserve Main ownership of runtime state and the rule that accepted work is not automatically replayed.
Use only read-only runtime diagnostics. Do not expose credentials, raw upstream request details, or unrelated Conversation content.

Confirmed that the visible run is stuck in its terminal-settlement path rather than continuing model or tool work.
The latest turn began at 11:50:10 local time. All observed upstream requests for that turn returned HTTP 200, its tools completed, and Pi persisted a final assistant message with stopReason: stop at 11:55:38.
The screenshot was captured at 12:02:14 while the UI still displayed 处理中 12 分 3 秒 and the stop control. At 12:10:08 the Pi session and Main log were still unchanged, the shared Agent Server remained alive but idle at 0% CPU, and it held no TCP connection.
The earlier 词元点数余额不足 rows are historical failed branches and did not cause the latest run to wait. The effective failure boundary is after final message_end: the run did not become idle, so agent_settled was either not emitted/delivered or did not take effect in Main projection.
No live run, process, project file, or product source was changed.

Correlated project/Agent/Conversation IDs from the local schema-v2 metadata.
Compared screenshot mtime, Pi JSONL mtime, Main log mtime, and wall-clock time.
Inspected the final persisted Pi message and the preceding completed tool results.
Checked the shared Agent Server process state, CPU time, and open TCP sockets.
Checked ADR-006 and the current event projector: message_end completes the assistant node, while authoritative agent_settled is required to set the run idle and release run ownership.

If a fix is requested, reproduce a long real tool-use turn whose final assistant message is persisted but settlement is missing, then harden the Agent Server/Main terminal handshake without replaying the accepted prompt.
Add regression coverage for final message_end followed by missing/delayed agent_settled, including safe recovery and release of run/background ownership.

None. This task records a live diagnosis only; any product behavior change needs a separate implementation task and verification.
