Daily Log: /btw Overhaul, /insights, /refresh all

/refresh all

Added /refresh all command — hard-restarts all non-human agents. Follows the same pattern as /sleep all and /suspend all. Extracted hardRefreshDir() from the existing hardRefresh() method.

Doctor hints updated to prefer /refresh over /cpr. Updated greetings (en/zh/wen), tutorial, and all i18n files.

/btw Inquiry Overhaul

The old /btw was fragile: wrote a .inquiry signal file, hoped the agent heartbeat picked it up, no feedback, no result display. Fixed with:

• IsAlive guard — refuses if agent is dead, shows “try /refresh”
• .inquiry → .inquiry.taken handshake — kernel renames on pickup, deletes after LLM call completes. TUI shows “thinking…” in status bar while .inquiry.taken exists.
• Result display — TUI tails soul_inquiry.jsonl, filters for source: "human", renders with markdown in a unified box (subtle bars, gold label, esc to dismiss).
• Source field — soul_inquiry.jsonl entries now tagged human/insight/agent. Migration m004 backfills source: "agent" on old entries.
• WriteInquiry guard — refuses to write if .inquiry or .inquiry.taken already exists. Prevents duplicate inquiries.
• Kernel threading — _run_inquiry() now runs in a daemon thread so the heartbeat loop isn’t blocked during LLM calls (was causing agent to appear “suspended” during inquiry).
• No-tools prompt — soul_inquiry() system prompt explicitly says “no tools, plain text only” to prevent MiniMax from hallucinating tool call XML.

.inquiry file format

First line is source, rest is question:

human
你还能干啥？

/insights Command

• /insights — manual one-shot trigger. Writes .inquiry with source: "insight" and the canned insight question.
• Auto-insights — toggle in /settings (off by default). Fires once per idle cycle (5s delay after active→idle transition). .insight.done sentinel prevents re-firing until human sends a new message.
• Rendering — same box style as /btw but with ★ insight label instead of /btw ›.
• Dismiss — press Esc to hide insights from default view. They reappear in ctrl+o verbose mode.

Settings Descriptions

Each settings field now shows a description line below when selected (en/zh/wen). “Insights” renamed to “Auto Insights”.

Kernel (lingtai-kernel)

• Thread-safe inquiry processing
• _persist_soul_entry accepts source parameter
• .inquiry file format with source line
• No-tools system prompt for soul_inquiry
• Bumped to 0.5.12, published to PyPI

Releases

• TUI: v0.4.32
• Kernel: 0.5.12 (PyPI)

Key Design Decisions

1. Inquiry stays inside agent process — considered lingtai inquiry as standalone CLI subprocess, but soul_inquiry needs the live agent’s conversation clone. Can’t construct a second agent instance (lock prevents it). Keeping it in the heartbeat was the right call, just needed threading to not block heartbeat writes.

2. .inquiry.taken handshake — provides three-state feedback (sent → taken → done) and crash safety. Kernel renames atomically, processes in thread, deletes when done. No retry logic — if crash happens, human re-triggers.

3. File-based guards over in-memory flags — WriteInquiry checks file existence, .insight.done sentinel on disk. Survives TUI restarts and avoids the cascading-insight bug that plagued in-memory state tracking.
