ask self-cancels in ~30ms: jiti reload recaptures PromptBus wrappers as ctx.ui originals

[joeshull]

Summary

Follow-up to #115 / #116. After the WeakMap originals cache, ask still self-cancels in ~30ms on a TUI session with no user dismiss. #116 stores pristineUiMap as a module WeakMap. Jiti module-cache invalidation (already called out for BRIDGE_KEY on process in bridge.ts) creates a new empty map, then getOrCreatePristineOriginals recaptures PromptBus wrappers as "natives".

The TUI adapter re-enters the bus. selectWrapper maps { cancelled: false, error } / missing answer to undefined. Dashboard ask-tool.ts treats any undefined as a user cancel (User cancelled ask.).

Observed 2026-08-13 on live ~/.omp-dashboard 0.5.4 with #116 already present, OMP 17.3.0, session source: tui.

Evidence (this session)

ask	start → end
1	21:52:25.605 → .638 (33ms)
2	22:10:06.998 → .027 (29ms)

Session: ~/.omp/agent/sessions/-code-zge-workspace/2026-08-13T21-52-14-327Z_019ffd1c-8bf7-7000-9129-177229e74139.jsonl

Tool result text is unique to packages/extension/src/ask-tool.ts (User cancelled ask.\nsample: []). Core OMP AskTool says User cancelled the selection.

Not the 300s PromptBus timeout. User did not dismiss.

Mechanism

1. ctx-ui-originals.ts const pristineUiMap = new WeakMap(...) dies on jiti reload.
2. Next session_start cache-misses and binds current ctx.ui.select (already __isPromptBusWrapper).
3. TUI adapter originals.select → wrapper → bus.request → TUI adapter → recurse.
4. Adapter error path from fix: stop ctx.ui re-patch nesting on session_start #116 (cancelled: false, error: ...) is still rendered as user cancel:
   • selectWrapper: r.cancelled ? undefined : r.answer
   • selectedFromAnswer(undefined) → cancelled: true

Repro (unit)

vi.resetModules() then re-import getOrCreatePristineOriginals and recapture the same ctx.ui after patching. Current main recaptures the wrapper (native select call count 0).

Suggested fix

Store the WeakMap on process (same pattern as BRIDGE_KEY / __pi_dashboard_bridge__), e.g. __pi_dashboard_pristine_ui__.

Also stop mapping adapter error / missing answer to user cancel in selectWrapper / ask-tool.ts.

Worktree with the process-map + failing-then-passing jiti test:
~/code/zge-workspace/worktrees/omp-dashboard/ask-prompt-jiti-originals (fix/ask-prompt-jiti-originals). Not shipped to ~/.omp-dashboard yet.
