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.
Owner round (2026-10-05): the same act (a human thinking in text) had two
visual languages — the quiz cards' quote block vs the practice container
with a collapsing chevron and raw pre-wrap text that read oversized.
- components/thinking-block.tsx: the quiz quote-block recipe verbatim
(rail + uppercase label + lh-prose at foreground/90) carried by a
faint user-side shell — ml-auto, max-w-[95%] mirroring the user
bubble's geometry, px-4/py-3 rhythm. Never collapsible. Rails reuse
the existing vocabulary: primary = committed register, muted =
working register.
- ThinkingCard becomes the practice adapter: 'Your solution' (primary)
/ 'Your thinking' (muted) — one component, two registers.
- The reading channel LIFTS out of the answered card: chronologically
prior to the question, it renders above it as its own user-side
block under the plain 'Your thinking' label; the in-card inset and
the 'while reading' phrasing are gone.
- lh-card-enter (globals.css): the one-shot 150ms fade+rise mount,
the app's motion register; honors reduced-motion.
- 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.
