Owner ask (2026-10-06): reveal everything the agent filled in when
writing the problem and concluding it, at the very bottom of the
conclude card, collapsible, arriving collapsed.
The fields, both calls:
- problem: mode (recall/discrimination/composition), target
proposition ids, statement, modelSolution (the last two ARE the
visible card — the drawer shows the metadata only)
- conclude: outcome, hint rung (R0–R5/null), miss class
(cue/discrimination/execution/careless/structural/null), retest.
Seams: problemInputForConclude (native-messages) walks the reveal's
walk and folds the WHOLE problem-call input onto the conclude part
(projectView join; same refused-pose law — an unacked pose folds
nothing); ArtifactPartProps grows problemInput. Targets resolve to
proposition NAMES at render (one lazy module-cached /api/graph fetch;
failure degrades to raw ids — observability never breaks the card).
The drawer: divider + chevron 'AGENT'S DATA' toggle (mono-caps
eyebrow register), definition rows with mono values, 'untagged'/
'none' honest empties, absent entirely when the calls filled nothing
(the dismissal line, legacy bare records).
Owner ruling (2026-10-06): every concluded problem opens a pause. The
agent may speak its closing words about the learner's last thinking
after the conclude result, then ENDS ITS TURN — a system-prompt law
deliberately, per owner correction, NOT tool-level terminate. The next
problem is never posed until the learner explicitly moves on; the pause
is the session's teaching space (repairs, clarifications, follow-ups —
still surgical, never re-teaching).
The move-on signal is a first-class input: { type: "next" } appends a
practice-next marker (content = single-sourced NEXT_PROBLEM_TEXT — the
model's unambiguous go-ahead: pose per the selection rules or wrap if
the arc is complete). Honest 400s: practice sessions only, nothing
active (mid-problem input rides the dock), riding after any pending
dismissal synthesis exactly like text.
The fast path (owner approved: composer-band chip + Enter-on-empty):
- Composer.enterAction gains "next" — Enter on an EMPTY composer in
the pause fires the signal; typing anything makes Enter a send again;
busy (steer/stop) outranks the pause.
- The Next chip hovers at the composer band's top-right (pick-pill
chrome register) whenever the pause is live and a problem has ever
been posed; the placeholder becomes the hint ("Ask about this
problem — or press Enter for the next one…", exact);
- the transcript renders the signal as a compact centered NEXT PROBLEM
line (mono-caps chrome); session-core appends it optimistically.
CONCLUDE_ACK_TEXT rewritten to carry the law; doctrine §VIII gains the
pause law (owner-sanctioned edit #3); 00-base's conclude/dismissal
bullets rewritten + the between-problems section added.
Owner round 2 (2026-10-05), Slice H: the Nudge/Commit two-lane buttons
are gone. One Send; Enter sends, Shift+Enter is a newline. Whether a
submission claims an answer is apparent from the thinking itself — the
agent reads it (hint ladder for traces, moves+verdict for claims).
- The thinking input loses the commit field end-to-end: ChatInput,
parseChatInput, newThinkingMessage (details and the model-facing label
both collapse to the single 'Your thinking'), the optimistic marker.
- Legacy records' commit flags are deliberately unread.
- Doctrine: the two labeled channels become one read instruction; 'answer
commits' section retitled 'Claimed answers' — a claim is not a
progress signal.
- ThinkingCard: one label, collapsed arrival (the unified row).
- The dock placeholder no longer explains lanes that no longer exist.
Owner round (2026-10-05), Slice C:
- ProblemCard: ALWAYS OPEN — the answered card's container + eyebrow
discipline ('Problem' label, lh-prose statement), no chevron, no
collapsed bar. The dock mirrors it in Slice D.
- ConcludeCard: the reveal is the modelSolution committed at POSE time,
shown verbatim as the hero — never re-authored (the slim schema's
law). The verdict rides below in the quiz-explanation register
(small, muted 'Verdict:' row). Nothing collapsible. Legacy inputs
with their own solutionReveal fall back to it.
- The reveal join: modelSolutionForConclude (native-messages.ts) — the
newest cleanly-posed problem before the conclude call; refused poses
reveal nothing. projectView enriches tool-conclude parts with
part.reveal at projection; ArtifactPartProps carries the field
(contracts/chat.ts).
Pinned: always-open problem card; hero-first conclude layout with the
verdict after it; legacy fallback; the join (clean pose, refused pose,
multi-problem records) and the view enrichment.
The bkt-practice record showed ONE turn in which the model concluded
(clean ack) and then every pose died on 'a problem is already active'
until it gave up ('the problem slot is stuck — the conclude calls report
success'). Two flaws, both fixed:
1. GATES READ A FROZEN RECORD. problem/conclude gates re-read the stored
record per execute — but the record freezes at the turn's write-ahead
(persistTurn lands only at turn END), so a mid-turn conclude → pose
pair could never see each other. practiceTools now builds ONE
turn-scoped gate (createPracticeGate) seeded once from the record;
the executes flip it. Fresh closure per turn (the agent is built per
request) — no cross-turn leakage.
2. PHANTOM ACTIVATION. activeProblemOf ignored tool RESULTS, so the
composer mounted from a pose the gate itself had refused (owner
ruling: 'either it goes through or it doesn't'). Honest activation:
a problem activates only on its clean ack; a conclude frees only on
its clean ack; errored and dangling calls are skipped. Retroactively
heals the BKT record (all its poses errored, all concludes clean →
no active problem). pendingProblemDismissalOf follows the same law
via the shared cleanToolCallIds helper.
Pinned: the mid-turn conclude→pose pair works in one toolset; the gate
re-arms after a successful pose; lone errored/dangling poses activate
nothing; a clean pose under a rejection stays active; an errored
conclude frees nothing.
- 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.
