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 2 (2026-10-05), Slice G: 'Solved' alone over unlabeled prose
didn't read as the model solution. The hero now carries its own 'Model
solution' section label (the quiz cards' register), and the verdict
section mirrors it — label muted, text at the same 50% register as quiz
explanations.
Owner round (2026-10-05), Slice D — the dock mechanics:
- INTENT-GATED FOLD: a ResizeObserver on the scroller's content stamps
the existing 400ms mute whenever the transcript GROWS — growth frames
(a live turn streaming under stick-to-bottom's chase) can never fold
the dock; and a fold now needs the distance AND stick-to-bottom's
isAtBottom agreeing the learner left. Fixes the generation churn
(dock disappearing and reappearing while the agent works). Shrinks
stamp nothing (the fold's own morph must not self-mute re-expand).
- MEASURED HEIGHT CAPS: the question (55dvh) and problem (40vh) areas
now cap at the available column (scroller clientHeight − 2rem,
re-measured on resize) via --dock-max-h — questions stretch to the
top bar with sensible padding and scroll internally only when
genuinely huge.
- The practice dock's statement area carries the 'Problem' eyebrow —
the quiz cards' label row, mirrored (dock and transcript card read
identically).
- The fold's CONTENT fade: a 160ms WAAPI fade/rise on the bar↔form
toggle — no remount, so the question form's state survives; the
shell height morph was already animated.
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 map picks no longer glue into the opening prompt as seed text
(owner, 2026-10-04 late). POST /api/chats accepts graphContext
{propositions}; the route resolves the picks against the live graph,
derives the reasoning chains among them (chainsForSelection →
formatChainLine), and writes a graph-context custom marker as
message[0] — before the learner's first user message, in either mode.
- Core: newGraphContextMessage (model-facing content = the
contextualization framing + proposition lines + chain lines;
details = the structured pick); toLlmMessages flattens it to a user
message like every marker, so the model reads it for free.
- View: projects to a user-side data-graph-context part.
- UI: GraphContextCard — minimal, muted, dashed, collapsed by default
(counts only); expand reveals name — statement rows and the chain
lines. Same compact-expandable pattern as the practice cards.
- Home: sends graphContext with the creation whenever picks exist;
the prompt param carries the learner's own words only.
- 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.
