- requiresReveal gates on pending.tool === 'quiz' (owner: only graded quizzes
arrive collapsed; ask/explain always open)
- ESC-abort chain opens AbortTurnDialog everywhere (owner ruling); from a
pending question abort IS dismissal — dismissedAnswer rides the answer
path, the teacher acknowledges the skip in its next turn; popup-Esc is
claimed via the state gate (two window listeners fire per Esc)
- 25-confidence.md: stripped the slider/JSON/calibration mechanics — pure
reading doctrine remains
- toolQuestionKind named once in core (dock parity), dock switched to it
Two owner rulings, 2026-10-01 ('nothing gets lost' round):
1. SUBMIT FINISHES DICTATION FIRST. Every submit path — the dock's
answer (Enter/Cmd+Enter/button) and the composer's send — stops any
live run and lets Deepgram's last finals land in the target field
BEFORE building the payload. Dictation.finish() resolves at cleanup,
post-flush; a module finisher registry (same pattern as the question
target) hands it to the dock without a prop bridge. Field values are
read from REF MIRRORS (thinkingTextRef/answerTextRef, the composer's
textRef): the flush lands via setState after an await, invisible to
the closure. The quiz flow the owner described now holds: dictate
reasoning → pick answer → pick confidence → Enter → dictation ends,
reasoning saved into the thinking field, THEN the answer submits.
The composer stays sendable while a run is live (its spoken text is
deferred in the run's buffer) so Enter can trigger the finish-first
send at all; nothing said → the send no-ops.
2. RUN END FOCUSES THE BARE COMPOSER. The falling edge of
dictation.active focuses the composer's textarea — only when the
composer is mounted: a pending question unmounts it (ref null, no
focus), so the thinking field is deliberately left alone. Composer
gains an optional inputRef for the page's focus handle.
The rail paint is extracted to components/confidence-rail.tsx (ramp,
tick stack, geometry laws) and shared by both surfaces so they cannot
drift: the dock's live slider paints the rail under its disc, the
answered card renders it disc-less — the missing handle itself says
'record, not control'. Same look otherwise: thin rail, stop color,
solid ticks, % read-out on the right, dock-mirrored placement (below
the options, above the thinking).
Renders only where a confidence exists: quiz answers with one sent;
never on 'I don't know' (none was sent), never on explain/ask, never
on pre-feature records (optional field, absent).
Round-4 regression, root-caused:
- The rail overlay (position:absolute) painted above the in-flow input
no matter the DOM order — CSS paints positioned elements after
in-flow ones — so the bar sliced across the disc ('disc behind the
bar').
- The wrapper's height was unpinned: the rail's top-1/2 centered
against a stretched box while the disc rode the input at the top —
vertical drift, which also exaggerated the disc's overhang and made
the original-size 16px disc read oversized.
Fix: the input is absolute inset-0 too (DOM order now governs — the
disc rides above the rail), and the wrapper is pinned to h-4 so rail
center and disc track share one box. Geometry otherwise unchanged from
round 4: rail spans the thumb-center range, 0/100 flush at the very
ends, solid ticks, no rim.
- 0/100 at the very edges: the paint moved off the input onto a rail
overlay spanning exactly the thumb-CENTER range (inset 8px = half
the 16px disc per side) — the disc rests flush against the rail's
ends, no bare stub poking past it. The input is now pure interaction:
full width, transparent, 16px-tall hit area, native drag.
- Ticks solid, not dashed; plain p% positions (the overlay IS the
center range), still background layers under the fill.
- Typing guard (owner): a range input is NOT a typing field — after a
click or drag on the slider the ↑/↓ option walk and ←/→ confidence
cycling keep working. Only real text fields (thinking, answer,
search, renames) own their keys. The slider's own keydown is gone —
the global machine owns arrows, and its preventDefault cancels the
native 1% step.
- Disc rim reverted: plain bg-current disc again.
Owner refinements 2026-10-01:
- Bar back to the original h-1.5 rail (colors unchanged).
- Disc bleeds into its own fill no more: 2px #141414 rim on the thumb
reads as a gap wherever it sits.
- Dashed stop ticks rebuilt as BACKGROUND LAYERS on the input itself:
#141414 base color, four dashed tick gradients (30/50/70/90 only —
the rail's ends already say 0 and 100) sized 1px x 100% at the
thumb-center inset, and the fill gradient now TRANSPARENT past the
thumb and painted on top — ticks live inside the bar, top to bottom,
visible only on the empty side, never over the filled portion.
Root-cause find: the sidebar 'highlighting' on ←/→ was :focus-visible —
pointer-clicked elements match it only after a keypress, so any key in
the quiz lit the still-focused session row. The arrows never moved
focus. Fix: the no-ring law (owner) — *:focus/:focus-visible outlines
removed app-wide in globals.css; surfaces keep their own affordances
and the dock's keyboard walk keeps its ring utilities.
Slider repairs:
- mousedown-preventDefault had killed click + drag in Chromium —
removed (with tabIndex -1); the slider is natively interactive again,
and the ring law makes its focus invisible anyway.
- Focused arrows step the STOP index on the input itself (native would
step 1% and snap straight back — dead keys); the global handler
skips INPUT targets, so no double-step. Enter still submits.
- Empty side: var(--muted) matched the card and vanished — now #141414
(the owner's main-background pick), and the pill carries a border
again (border-border).
- Dashed tick per snap stop below the bar, inset by the thumb's
half-width so each tick sits under the thumb's center at that stop.
Owner UI round 2026-10-01, three rulings on the slider plus one en-route
bug:
- GLOBAL ←/→, the ↑/↓ pattern: confidence adjusts wherever focus sits
(window keydown, typing-guarded), no click-in, no focus ring. The
slider itself takes NO focus — tabIndex -1, mousedown prevented,
removed from the Tab chain (rows → thinking directly again).
- Position = fraction: the thumb's scale is 0-100 with the rendered
value the stop's own percent, so 50 sits halfway; onChange snaps to
the nearest stop (magnet feel while dragged).
- Six-step ramp (owner pick over three bands): 0 red, 30 orange,
50 yellow (the coin flip), 70 lime, 90 green, 100 emerald — fill AND
handle wear the stop's color; taller 10px pill bar, custom track/thumb
(webkit + moz), muted remainder via --muted.
- Plan-flank phantom: gating the marginalia button on a JSX element
(always truthy) mounted an invisible clickable button in the
bottom-right whenever a question was pending with no plan.
planExists() now gates it (pinned in plan-window tests).
Owner design round 2026-10-01: every multiple-choice quiz answer now
carries the learner's stated probability that his selected answer is
correct — calibration data for the prober and teacher, the flow itself
unchanged.
Definition (owner ruling, after weighing chance-normalization): RAW
probability. Sub-chance reports are diagnostic gold, not dead space —
'picked an option, believes it wrong' is a real state. The agents get
the sophistication: new shared/25-confidence.md composes for both
agents (chance level, sub-chance = distrusts the pick, correct+low =
fragile, wrong+high = committed misconception, IDK = genuine gap).
- question-core: AnswerRequest/QuestionAnswerData.confidence (quiz
only, optional — old records valid), buildAnswer clamps and drops it
on dontKnow, formatAnswerMessage states the line, CONFIDENCE_STOPS +
DEFAULT_CONFIDENCE_INDEX exported.
- question-dock: snapped slider below 'I don't know', above 'Your
thinking' — native range over the stop INDEX so ←/→ step the uneven
grid cleanly, Tab chain rows → slider → thinking, Enter submits from
the slider too. Rests at 50 and always sends (owner: 50 must mean a
real coin flip, never 'untouched'). 'I don't know' GRAYS it out —
layout holds, no value sent.
Deliberately untouched: explain free-recall card (quiz-only scope),
answered-card rendering of confidence, ask flow.
Two follow-up rulings on the explain tool:
1. No 'I don't know' row — not needed in free recall. If he doesn't
know, he says so in his own words; his text is the only answer
channel. Dock: text mode is rowless again (the composer IS the
surface); doctrine and the shared prompt chunk updated; the format
branch and card revert to quiz-only dontKnow.
2. explanation + correctAnswer collapse into ONE field — the separate
explanation was quiz remnant (MC needs the why outside its options;
a free-text commitment carries its own reasoning). Schema is now
{question, correctAnswer, details?}; the reveal shows the single
committed answer; no explanation snapshots anywhere on the explain
path.
1047/1047 tests, typecheck/lint/build green.
Sycophancy mitigation as a structural commitment: the model writes its
full correctAnswer (plus explanation, in that order) BEFORE the learner
sees the question; the commitment rides the persisted call args, is
revealed on submit, and grades his free text in the model's next reply —
the client never grades free recall.
- tools.explain setting (segmented 'Quizzing — Multiple choice | Free
recall' in Agent settings' Tools group): free arms explain and drops
quiz for BOTH agents (prober variant carries no nodeId, same pattern
as the probe quiz); mechanics keys never pass filterEnabledTools —
quiz stays unwritable (the 2026-09-19 wedge ruling stands)
- doctrine lives pi-natively in the tool descriptions (owner ruling —
no conditional system-prompt chunks): explain carries the commitment
rule; the MC option-building craft moved out of the prompt into the
quiz description; shared/20-question-tools.md slims to the
quiz-agnostic core
- display seams: parseExplainInput (LaTeX-debris restoration included),
dock text-mode with an 'I don't know' row (kbd row 0), AnsweredCard
reveal (The answer / Why, no verdict chips), [Explain answer] format
- phases/plan seams recognize both quizzing tools' nodeId tags; explain
answers deliberately feed no ledger evidence (no client grading to
key on — a future ruling can parse the model's grade)
1049/1049 tests, typecheck/lint/build green.
Three owner rulings from the gradient-descent session
(chat_muhskq6p_e8c3600b — 7 failed quiz calls, answers leaked in
option descriptions, planning divider floating at the transcript top):
1. RETRYING LINES (general): any tool call that errors back to the
agent (validation failure, malformed args — the retry loop) renders
one quiet "Retrying…" SystemLine instead of silence. Question tools
previously rendered null, so a flailing quiz loop read as a stall.
Aborts are terminal ("Operation aborted") and stay silent. Verified
live: exactly 7 lines render at the 7 failure sites of the session.
2. QUIZ OPTION DESCRIPTIONS: NUKED. The model used them to telegraph
correctness in every quiz of the session ("that moves uphill — it
climbs f instead of descending it") — answerable by elimination.
The field is gone from BOTH quiz schemas (probe + teach); ask keeps
it (ungraded — nothing to leak). The dock additionally suppresses
descriptions for quiz kind, so pre-fix records stop leaking too.
Verified live: the session's pending quiz renders bare labels.
Plus the diagnosed failure-mode fixes: GLM sometimes emits `options`
as a JSON-encoded string (6 of 7 failures). prepareArguments hooks
on all three question tools coerce it BEFORE pi's validation (the
call lands instead of bouncing); the client coerces again in
normalizeOptions (pi persists raw call args). Schema descriptions
hardened ("REQUIRED ... never a JSON-encoded string").
3. DIVIDERS AT THE MARKERS: the probe-handoff SystemLine
("Preparing your plan…") IS NOW the Planning divider; the accepted
verdict IS NOW the Teaching divider ("✓ Plan accepted" line gone) —
one signal per seam, not two. The fold-based divider block is
DELETED: Wave D grouping merged the whole probe into one giant
assistant group, so the inclusive-fold comparison floated the
divider to the transcript top (reproduced against the real record:
6 view messages, phase flipped at the giant group). The markers
render in the right spot by record construction. A DECLINED verdict
is not a seam — it keeps the "↻ Plan revision requested" line.
Verified live: plan divider after the probe concluded, teach
divider after the plan presentation, nothing at the top.
Tests: 1004/1004 — string-coercion pins (normalizeOptions + the
prepareArguments hooks on all three tools, identity fast path),
quiz-schema-has-no-description pin (ask keeps it).
Two owner fixes (refinement round 2, 2026-09-24) in the question
dock's ask questions (quiz untouched):
1. ESC ESCAPES THE OTHER TYPING: the ask's "Type your own answer…"
row auto-focuses its input on selection, and once in it there was
no way out — arrows moved the caret (the typing-surface guard), so
keyboard navigation was stranded. Esc in that input now blurs it
(focus falls to the page) and pins kbdIdx to the Other row, so:
the row STAYS selected (deselection is a deliberate act, never a
side effect), the typed text survives, the arrow walk resumes
immediately, and the row stays the walked row. stopPropagation
keeps the window chain from reading this Esc as abort-turn.
2. SPACE DESELECTS A SELECTED OTHER: the walk's Space on the Other
row selected it; now Space on an already-selected Other CLEARS
the pick — focus never drops back into the typing field (the
core's toggleOther has no single-select off-path; the off-path
lives in kbdAct, keeping `selected` intact in multi). Re-selecting
— walking back and Space, or a click — is the way back into the
field. Clicking the selected row keeps its old meaning (choose
Other); only the walk's Space gained the off-path, per spec.
3. MULTISELECT CHECK GLYPH BIGGER: the ✓ inside the multiselect
checkboxes drew at the 11px text-xs rung — small next to the 16px
box. Now text-base (14px on this app's ladder) + leading-none.
The single-select dot and the quiz's rows are unchanged. (Pinned
live: 14px computed in the 16px box; the span only mounts on a
checked row, so no static pin — noted in the render test.)
Live-verified on :3001 (fabricated ask chats, keyboard-only flows):
select via Space focuses the input; type; Esc → focus BODY, row
still selected, text kept; Space → deselected, focus stays out;
re-select → input focused again; listed option displaces in
single-select. Multi: Other coexists with checked options through
the whole sequence. 901/901.
Tab/arrow focus on quiz/question option buttons and the don't-know row
showed Chromium's default focus ring — the abandoned look. outline-none
on the row buttons keeps the walk ring (bg-accent/40) as the only focus
indicator, so the appearance is identical before and after Tab.
Owner live-test rounds on waves A/B:
- Alt+arrows no longer ALSO walk the question rows (dock ignores
alt/meta/ctrl combos; session cycling keeps them exclusively)
- question walk clamps at the ends — no wrap (faster to navigate)
- plain Tab toggles focus between the thinking field and the answer
rows (walked row by default); focus follows the walk while in the
rows; Shift+Tab stays the global thinking-level cycle
- Esc in the sessions search blurs back to normal (claims the key so
the window Esc chain does not fire)
- cheat sheet gains the Tab-in-question display entry
The shortcut architecture (owner-approved plan, 2026-09-17):
- src/keyboard.ts: pure action registry (id, label, scope, default
binding) + lh:keymap localStorage overrides + event normalization.
The settings milestone renders this same registry as its editor.
- components/keyboard-shortcuts.tsx: the single document-level keydown
listener (window level, bubble) owning the pieces no surface owns:
- Tab is DEAD (owner decision): browser tab-focus navigation is
abandoned; Tab is suppressed everywhere, Shift+Tab cycles the
thinking level.
- Esc is a layered dismiss: topmost popover first (popovers
stopPropagation their own Esc — usePopoverDismiss + ModelControl),
then dictation stop (lh:kbd-stop-dictation), then abort of an
in-flight turn (lh:kbd-abort-turn; server-side wake turns are
honestly non-stoppable — the seam only stops local streams).
- Global actions dispatch lh:kbd-<action> window events (the
lh:chat-renamed pattern); surfaces that aren't mounted simply
don't listen.
- The input guard: inside a typing surface only mod/alt combos (and
Tab) fire; bare keys pass through to the field.
- Cheat sheet overlay (?) renders from the registry, grouped by scope.
Bindings wired this wave: cmd+d dictation toggle, cmd+k model picker,
shift+tab thinking cycle, cmd+b sidebar, cmd+shift+f sessions search,
alt+up/down + alt+enter session cycling, cmd+g graph view, cmd+n new
session, f2 rename (chat), ? cheat sheet. Wave B adds the question
keyboard machine; wave C the per-surface bindings (find, import).
Verified live in the dev shell (CDP): all of the above via
Input.dispatchKeyEvent.

Owner's first live mic test (2026-09-17) drove four changes:
- ONE primary transcription input at all times: while a quiz/ask
question waits, finals land in its field (text mode → 'Your answer',
select modes → 'Your thinking') via a module-level claim registry
(useDictationTarget in dictation.tsx); the composer is the fallback.
Esc in a question field also stops dictation (threaded through
DockOverlay → QuestionDock).
- No interim results: live words were distracting and shifted the meter.
Params now match the pi dictate extension exactly (no interim_results,
endpointing=300, no utterance_end_ms); the meter's width stays fixed.
- Optimistic meter: the click enters the meter view immediately (Stop
pill + meter within one frame, verified at 150ms in the dev shell);
token mint and mic acquisition run concurrently behind it.
- Wide idle button: the stats-bar middle is one full-width affordance —
a quiet bordered 'Dictate' button when idle (failure text replaces the
label), Stop pill + fixed meter while live.
Live-verified in the Electron dev shell: wide button renders on home
(167px) and chat (358px), meter + Stop appear at 150ms after click,
flat 2px bars in silence, clean return to 'Dictate' on stop.
The system: the ladder is the truth, everything snaps to it.
- Prose snaps to the ladder's 16px rung (--lh-prose-size 16.5→16; the
half-pixel was a reskin-era hand-tune with no visible payoff and a
system cost). lh-prose, lh-input, and the session titles all read the
one variable — one reading size, now a ladder citizen. @theme inline
inlines literals without emitting runtime vars, so the variable can't
var()-link to --text-lg: documented as the one deliberate duplication
(change one, change both).
- The 10px rung merges into 11px: one pixel apart was a distinction with
no visible difference, and 10px sits at the mono legibility floor —
quiet labels (Sessions, Background agents, dock hints, model-picker
footers) get their quiet from color + tracking, not a notch of size.
All 13 text-xxs uses → text-xs; --text-xxs token removed.
- Derived constant follows: TEXT_CAP_SCALE 16.5/12.5 → 16/12.5 (1.32 →
1.28; test pin 232.32px → 225.28px) — the plan-graph text cap now
tracks the snapped prose size.
Live: title 16px, Sessions/Background-agents labels 11px, composer 16px
with the 20px lh-input line box. Gates: typecheck, lint, 469/469.
Lane note: components/graph-context-marker.tsx (graph-stream file) had a
mechanical text-xxs → text-xs swap — required: the token removal
otherwise leaves a dead class in their file.
- lh-input: lh-prose's 1.5 reading leading made typing carets tower
(~25px box on 16.5px text, ~2.1× the glyphs — the caret fills the line
box in Chromium). Inputs are not paragraphs: 1.25 leading drops the
caret to ~21px, the font-metric floor (as close to the glyphs as
Chromium will draw). Swapped on every typing surface — composer
(chat + home), the thinking field, answer + editable-Other inputs, the
model search; rendered prose (message.tsx container, option
descriptions, chat.tsx pre-wrap) keeps lh-prose 1.5. Same family and
size as prose; only leading differs.
- Session titles: 14px (text-base) — Source Sans at 12.5px read as
small as the 11px mono meta under them; the title now holds its rank.
Live: title "Source Sans 3" 14px vs meta "JetBrains Mono" 11px, row
52px; composer line box 20.625px (was 24.75px).
Gates: typecheck, lint, 469/469.
- ✓/✗ in the answered card: replaced literal glyphs with lucide CheckIcon/
XIcon (strokeWidth 2.5) inside a fixed size-4 flex box — text elements
never carried the right size/vertical alignment, vectors do. Test pins
updated (lucide-check/lucide-x classes).
- All user-typed INPUT text now matches markdown output: lh-prose class
replaces the earlier font-prose (family-only) band-aid on the composer,
question-dock text/thinking/Other fields, home topic input, model search
box, and answered-card 'your thinking'/free-text records. lh-prose sets
family+size (16.5px) so placeholders inherit correctly.
- Home view: StatsBar under the composer (model+thinking control) — the
DOCK geometry matches the chat view (max-w-[46rem] px-4) so nothing
shifts when a session starts; pre-chat selection persists via deferred
save (ModelControl chatId-empty) + PUT after POST /api/chats.
- Answer marks (✓/✗): same visual size as row text, vertically centered;
colored green-500/red-500 matching the verdict chips.
- All user-typed inputs (composer, question-dock text/thinking/Other,
answered-card 'your thinking' and free-text records) now render
Source Sans 3 via the font-prose utility. Placeholders inherit the
family via the element.
- Answered-card explanation: markdown wrapper made truly inline so the
'Why:' label + the paragraph sit on one line — removes the oversized
leading gap.
- New session: literal '+' glyph removed — one lucide PlusIcon (the
duplicated glyph was PlusIcon + text '+').
- Top bar: a small pointer-events-none gradient under the header eases
the scroller into the bar exactly like the dock's bottom fade.
- Option subtext (opt.description): .lh-prose — Source Sans 3; 'I don't
know' copy stays JetBrains Mono.
- 'I don't know': now layout-matched with a radio circle; dashed border
preserved as the deliberate non-answer.
- Separator spacing: options group pb-1 → pb-2 so the gap before the
divider equals the 8px inter-option gap.
--text-xxs (10px) joins the ladder; every component-level text-[9|10|11px]
literal in owned components now pulls from the ladder (graph-view.tsx and
home.tsx untouched — graph stream). Cosmetic pins updated where touched.
The architectural answer to the validation-crash question: validation IS
first at the model-facing boundary (pi validates arguments before
execute; failures return to the model same-turn — all three live
incidents retried successfully). But the same bytes also exist UNVALIDATED
by design in two other places: the live wire streams raw tool-input
deltas DURING generation, and the transcript keeps the raw input of
REJECTED calls (honesty + the replay invariant). The consumers were
supposed to trust part STATES — but that trust was enforced by
TypeScript casts ('part.input as X'), which are compile-time lies with
no runtime check behind them. That is the hole both crashes came
through, and it should not have been possible.
The structural rule now: model-authored INPUT is consumed only through
parsers running the SAME zod schema the model faced — boundary-valid ⇔
consumer-parseable, mechanically. Server/learner-authored OUTPUT stays
trusted (our code authors it).
- src/core/tool-parts.ts (new): parseQuizInput (display parse over the
shared quizInputBase — strips the teacher-only nodeId, accepts both
prober and teacher boundary shapes), parseAskInput, parseProbeDoneInput.
- contracts/probe.ts: probeDoneInputSchema is now core-owned zod — the
probe_done tool declares it (single source of truth), the seam runs
the literal same schema.
- question-dock.tsx: the dock parses its input at entry; unparsable
renders the quiet malformed-question fallback, never a crash.
- probe-done-card.tsx: the input preview goes through the parse; the
old state reasoning and shape guards collapse into it.
Pinned in tests/tool-parts.test.ts: both exact live crash shapes
(stringified quiz options, stringified assessment), boundary-parity
cases for all three schemas, nodeId stripping, mid-stream partials;
render-cards pins the dock fallback markup.
Gates: tsc, lint, build, 328/328.
Two live bugs from the modal-realism stress runs:
1. Multi-select ask: picking the custom 'Other…' row cleared every
already-picked option, and picking any option cleared a typed custom
answer — single-select displacement logic applied to both modes. The
dock's selection is now a pure state machine in question-core
(toggleOption/toggleOther over DockSelection, unit-tested): single
displaces (unchanged), multi coexists — neither channel clears the
other; the typed text always survives.
2. ProbeDoneCard crashed on a REJECTED probe_done call: the model
stringified 'assessment' (the same double-encoding habit as the
options bug), zod rejected the call, the model retried — but the
card's input-preview fallback trusted the errored part's unvalidated
input shape and died on assessment.strands.map. The preview now reads
input only while the call is pending or streaming (guarded with
Array.isArray); an output-error part renders a quiet
malformed-and-retried note instead of the garbage.
Pinned: question-core.test.ts (3 dock-selection machine cases),
render-cards.test.tsx (4 probe-done card cases incl. the exact live
stringified shape, plus the multi-select ask markup pin).
Gates: tsc, lint, build, 315/315.
Key-convention policy, settled: every field accepts ⌘/Ctrl+Enter
(metaKey || ctrlKey — Mac gets ⌘↵, Windows/Linux Ctrl↵, the Gmail
convention); plain Enter stays matched to the field's species —
sends in message fields (chat composer, free-text answers — the
universal chat convention, Shift+Enter still a newline), newline in
the thinking field (composition, for dumping).
- The learner's own typed Other answer now renders INSIDE the options
container in the answered card, styled exactly like its selected
siblings (border-primary bg-accent) — it is an option, not a loose
quote floating outside the list. Quotes keep the learner's words.
- The thinking field submits with ⌘↵ on macOS, Ctrl↵ elsewhere
(metaKey || ctrlKey — the Gmail convention, same handler on every
platform). Plain Enter stays a newline: the field is for dumping.
A quiet "⌘/Ctrl + ↵ submits" hint sits next to Submit for
discoverability (text mode keeps Enter-to-submit, no hint).
The note was the transfer channel of the whole product presented as an
afterthought: an unlabeled one-line slot whispering "optional". Now:
- A labeled composer-TWIN field ("Your thinking") between the options
and Submit, docked with the submit button inside it exactly like the
chat composer's send. The placeholder invites dumping ("Why this
answer? What are you unsure about? Say as much as you like — the
teacher reads all of this."); the word "optional" is banished.
- Enter makes a NEWLINE in the thinking field (it is for dumping, soon
dictated); the button submits. Text-mode answers keep Enter-to-submit.
- Phase-scaled prominence: teaching = a generous dump area, probing =
one quick row (threaded from the session phase via DockOverlay).
- "Other…" (ask questions) is now an editable OPTION ROW — radio circle
that fills on selection + inline input, styled like its siblings — so
picking Other never displaces the thinking field; typed text survives
deselection.
- The answered card promotes the thinking to a quoted first-class
block above the verdict, labeled "Your thinking" — the transcript
reads as a dialogue of thinking, not a buried "Note:" footnote.
The frozen core is untouched (the teacher-facing "Note:" transcript
line in question-core.ts is protocol text, flagged to master).
Compared the port against the original pi setup
(vault/π/learn/.pi: quiz.ts, ask-user-question.ts, teach SKILL.md) —
the pi version never produced invalid correctAnswer values. Root cause
of the port's validation failures: the pi options schema's 'Give each
option a stable value; you reference the correct one by that value in
correctAnswer' sentence was dropped in the port. Without it the model
omits values and must copy a long natural-language label verbatim into
correctAnswer — and instead slugifies it ('cultural-diagnosis' for
'A cultural diagnosis') every turn.
Now matched to pi:
- quiz schema: pi's field order (question, details, options,
multiSelect, correctAnswer, explanation) and descriptions — options
carry the stable-value instruction, correctAnswer is phrased as a
value reference ('the value field of the option you intend'), not a
copy-exact-or-fail threat. nodeId (lh-only, graph) stays.
- ask schema: dropped the redundant 'mode' param (pi has none; the dock
already infers from options presence), pi's descriptions.
- quiz tool description: pi's full text (ask contrast, note field,
dontKnow semantics) minus terminal-only details, plus lh's turn
protocol sentence.
- system-prompt: fixed the stale 'exactly two tools' line (plan/research/
demo/visual tools have their own sections).
Not matched, deliberately: tool results stay JSON (pi sends curated
text; formatAnswerMessage exists if we want it later), shuffle param
(lh always shuffles seeded), pi's ask '(Recommended)' label hint.
The shell now imports through exactly two barrels, enforced by
import/no-restricted-paths (npm run lint):
components/** -> "@/src/core" (pure core API, browser-safe)
app/** -> "@/src/core" + "@/src/server" (server entries)
Zone violations are lint errors with architecture-pointer messages; the
pure-core modules (contracts, question-core, plan-tree, phases, pending,
math-delims, ui-message) may never import agent/server/store.
Supporting moves (direction: IO layers -> core):
- core/index.ts: the core public API barrel
- core/ui-message.ts: moved from src/agent (it was shell-facing all along)
- quiz/ask input zod schemas moved agent/tools -> core/question-core
(the question contract, alongside the grading logic)
- ChatRecord/ChatSummary moved store/chats -> core/contracts (single schema)
- GraphSnapshot/NodeStateClass moved core/graph -> core/contracts (the
/api/graph payload IS a contract; the pure renderer needs only these)
- src/server/{chats,graph,jobs}.ts + index.ts: thin server entries for the
transport layer; GET /api/graph's fold side-effect now lives behind
graphView() instead of inline in the route
Gates: tsc clean, 190/190 tests, eslint clean (law verified to fire on
store/agent/subpath violations), production build clean.
(Repo repair en route: a git object (app/chat/[id] tree) was missing from
the object store — reconstructed byte-exactly via mktree from its blob;
the broken node_modules that stalled the build was cleanly reinstalled.)
- Animation: the blob's shell morphs height (WAAPI, 180ms) on every
variant change — chat ↔ question ↔ collapsed bar — plus a quick
fade/rise (160ms) on the swapped content. Gotcha pinned in code: never
measure the shell while a morph is in flight (getBoundingClientRect
reads the ANIMATED value and corrupts the next morph's start height);
cancel running morphs before measuring, refresh settled height only
when no morph is running.
- Gradient-over-scrollbar fixed structurally: the dock is no longer an
absolute overlay on the conversation root — it's sticky bottom-0 INSIDE
the scroller (in flow). The transcript scrolls fully clear of the dock,
the fade never touches the scrollbar lane, and the pb-hack clearances
are gone.
- New question while at the bottom scrolls to reveal the dock; scrolled
up → collapsed bar, no yank.
- Thin dark native scrollbar app-wide (8px webkit + scrollbar-width:thin,
dark thumb, transparent track). Note: use-stick-to-bottom sets
scrollbar-gutter: stable both-edges on its scroller — the lane is
outside the content flow by design.
- 'Writing a question…' transcript shimmer while a tool call streams its
input (same slot as 'Thinking…'). Protocol pinned by a test asserting
tool-input-start precedes tool-input-available; scripted mock now
streams tool input as deltas like real providers do. (OpenRouter/
Anthropic often delivers the whole input in ONE delta — then the dock
appears instantly and no indicator is needed or shown.)
Verified live: grow 54→349px and shrink 349→54px fire with correct
from/to; collapse/expand intact; gradient stops before the gutter;
Thinking… observed in-page; 58/58 tests.
- A pending quiz/ask now REPLACES the chat composer: one persistent
rounded-2xl shell in the transcript overlay swaps contents (composer ↔
question ↔ collapsed bar), never remounting — the structure a future
grow-morph animation needs.
- Unified bottom row inside the question: the note field (select modes),
the answer field (text-mode asks), or the Other text — one field, one
'Submit answer' button, Enter submits.
- Collapse on scroll: uses useStickToBottomContext — scroll up and the
dock folds to a slim bar (kind chip + LaTeX-flattened question teaser +
'tap to answer'); click scrolls to bottom and re-expands. The expanded
form stays mounted-hidden so a half-made selection survives.
- Pending/streaming tool parts no longer render inline; answered parts
land in the transcript as graded cards on submit. Question generation
shows a shimmer in the shell.
- Composer back to pure chat (no mode machinery); quiz-card.tsx and the
pendingText/registerSubmit bridge deleted; render tests re-pointed at
the dock (wrapped in StickToBottom).
Verified live: docked quiz submit (note+selection), ask-text Enter
submit, collapse/expand with selection survival, bar teaser text.
