- PracticeDock (components/practice-dock.tsx): the active problem
replaces the composer — statement (markdown+LaTeX) above, the 'Your
thinking' composer-twin below with the two submit lanes (Nudge =
thinking without a commit; Commit = answer commit; ⌘/Ctrl+Enter
commits). Dictation claims the thinking field.
- Transcript cards (practice-cards.tsx + the artifact registry): the
problem card (compact-expandable statement — the commitment NEVER
renders), the conclude card (outcome + verdict + reveal; the
dismissal synthesis is one muted line), and the user-side thinking
register cards (Your thinking / Your solution).
- view.ts: the problem pose joins the placeholder fork (the ack never
flips the part); practice-thinking markers project as data parts;
problem-dismissed markers project nothing.
- chat.tsx: activeProblemOf drives the dock branch (question > problem
> composer), the esc layering gains the problem rung (below question,
above turn) with its discard confirm + the silent marker route; the
thinking submissions POST through the session's optimistic appends.
Esc over a mermaid focus, the plan popup, or the setup dialog opened the
question-dismiss confirm underneath — KeyboardShortcuts' window listener
registers first, so the overlays' own self-closing Esc listeners could
never outrun the lh:kbd-abort-turn dispatch. The state gate in ChatView
is the defense (the architecture's own pattern from the abort dialog):
escAbortTarget, exported pure, rules priority by stacking order — abort
confirm (claimed by its dialog) > mermaid (paints above plan) > plan >
setup (self-closing) > question > turn. The gate closes the overlay; the
overlays' own listeners stay (idempotent). Pinned in esc-layering.test.
