- needsContinuation: a persisted problem-pose ack (terminate:true ended
the turn deliberately) owes no continuation — reloads after a pose no
longer wake a phantom turn; error results stay owed like any
interrupted tool.
- Chat header: practice sessions swap the phase chip for a quiet
Practice tag (no probe→teach arc applies) and hide the coverage ring
(practice never extracts — an ever-filling ring would lie).
- ChatSummary gains pendingProblem (activeProblemOf at projection); the
sidebar meta says 'Problem waiting' for a practice row with a posed
problem. Kind threads through Chat/[id] page.
- Home picker chip gains Clear (picks were otherwise irremovable).
The native shapes beneath the practice tools (owner design 2026-10-04):
- activeProblemOf — the conclude-before-next-problem gate's fold (a
conclude call OR a dismissal marker deactivates; the pose-time ack
never does — nudges keep the card up).
- The thinking input: {problemCallId, commit, text} → practice-thinking
marker; the label (THINKING_HINT/COMMIT_LABEL, single-sourced in
contracts) is the only register difference the model sees.
- Ask-style problem dismissal: silent route appends the UI-only marker;
the user's NEXT input prepends the synthesized conclude pair (call
outcome:'dismissed' + shared ack) so the agent reads the discard in
its own vocabulary and the slot frees.
- toLlmMessages: dismissal marker filtered; pair passes natively.
