- The setup pickers opened invisible: React attaches a host element's ref
AFTER descendants' layout effects, so MenuShell's mount-time place()
measured a null anchor and gave up — the menu stayed hidden until a
window resize re-ran place(). The stage-2 slot and thinking menus now
anchor by anchorTestid (querySelector at place time, the settings-menu
pattern) instead of the conditionally-attached triggerRef.
- Saving models NEVER auto-sends the queued message (owner ruling,
2026-10-09): the draft waits in the composer and the learner sends it.
The replay/draft-send calls removed from onDone in new-session, home,
and chat; the dead force machinery removed from send/start/begin.
- The setup CTA pills get the app-wide hover language (hover:bg-accent +
cursor-pointer) — hover:bg-muted was invisible because --muted and
--card are the same #1c1c1c.
The smoke found it: Tab from body on home preventDefault'd but never
focused — home does not render the shared Composer component; its
composer is the bespoke topic textarea, and the selector matched
nothing. The chain is now topicInputRef itself.
Also verified live this round: the one-Esc law on plan/chains/settings
(exactly one action, nothing stacked), Enter-submits from the Other
input (a real session filed the custom answer immediately), and
Shift+Tab staying the thinking-level cycle everywhere.
1427 tests, tsc, lint, build green.
Plain Tab now navigates instead of being pure dead weight: the global
handler dispatches lh:kbd-cycle-fields and each composer-bearing
surface answers with its own chain, gathered from live DOM at event
time (the docks mount and unmount — refs would go stale):
- chat: reading-thinking → the active dock's field → the composer,
visual order, wrap; Tab from anywhere else focuses the first live
field (navigate in)
- new-session + home: the composer is the whole chain — Tab navigates
into it
Shift+Tab is untouched (the thinking-level cycle keeps it — owner
ruling); the quiz dock's rows↔thinking Tab claim stops propagation at
document level, so a claimed Tab never reaches the dispatch — no
double act.
1427 tests, tsc, lint, build green.
The chains-as-home experiment is retired (owner, 2026-10-06): dragging
the table out of its overlay home caused every mess we saw — checkboxes
by default, the bar/pill collision, the clearance band. The eventual
plan is the DATA VIEW as home; until that is designed and built, the
rendering-off home is deliberately minimal:
- The SAME composer blob home already floats — teach/practice switcher
and pick pill untouched.
- The graph chrome's survivors in the graph view's OWN places: the
top-right column — actions row (Chains + Import, the same 36px band
pills) with the cost pill BELOW it. Import always renders (the
entry-point law). No node search, no render gear (canvas things).
- A quiet centered summary (KnowledgeSummary, a pure body — pinned by
the render suite): propositions · chains, teaching · practice session
counts, the imported-sources list as truncated muted rows; the empty
knowledge base says so and names the import entry point. Biased up
off the composer (pb-40), pointer-events-none.
- NO recent sessions (the sidebar owns that, owner ruling).
The chain table returns to overlay-only duty: ChainTableBody's
onClose-optional and topBarExtra experiment hooks are reverted, and
components/chains-home.tsx is deleted. MinimalHome renders the STANDARD
ChainTableOverlay behind its Chains button — the pick flow mirrors
GraphView's contract verbatim (chainSelectOpen raises the overlay in
select mode; Done reports the lifted pick set down).
Smoke-verified live, twice: the summary shows real counts (262 props ·
160 chains, 195 teaching · 17 practice, 4 source paths); overlay
open/close via button + X; pick flow — cluster check → bar "23 nodes →
17 chains · Clear · Done" → uncheck 2 props → Done → chip "21
propositions selected"; practice session starts from the composer;
settings restore returns the canvas home. (First run's "select mode
missing" was a tester artifact: the bar is selection-gated and prop
checkboxes render only when expanded — both confirmed working.)
1417 tests (new KnowledgeSummary pins); tsc, lint, build green.
The settings Graph section splits into two switches (owner, 2026-10-06):
- EXTRACTION (was the lone "Graph" row): the DATA channel — pipeline,
auditor, prober graph tools. Key unchanged (graph.enabled), label now
names its job; off = the graph stops growing, nothing is deleted.
- GRAPH RENDERING (new, graph.rendering, default on): display-only.
Off = the home's main view is the CHAINS VIEW instead of the canvas;
data, reasoning-chain model, and the pipeline keep working untouched.
The chains home (components/chains-home.tsx): ChainTableBody in flow —
same body as the overlay, same powers (query + sort, selection, the
delete fence with its confirm dialog), but onClose is absent so the
top-bar X does not render (the table IS the page; ChainTableBody now
takes onClose optionally). The chrome survivors float top-right below
the top bar: Import notes (ALWAYS — the entry-point law) + the cost
pill (GraphCostControl, now exported). The composer blob persists over
everything; the table scrolls CLEAR of it via a fixed pb-40 band (text
under a floating box is noise — unlike the canvas, which runs under).
Pick flow mirrors the overlay contract exactly (home lifts the pick
set; selectMode swaps the bar's confirm to Done). The chip relabels to
"Pick propositions" (no "from the map" — there is no map); while
picking, the chip row hides so the floating bar above the composer is
the one voice. Settings resolve rendering through the one core
resolver + renderingEnabled(); read server-side per navigation, so the
switch applies on the next visit home.
Smoke-verified live (headless browser): chains home renders without the
X, import + search + composer clearance confirmed, pick flow checked 2
propositions -> Done -> chip count -> practice session started with the
graph context carried (2 props, 2 chains), settings restored.
Known follow-ups (flagged, not built): after Done the bar morphs to the
table's Clear/Delete management bar while the chip also shows the count
(two voices, same set — the table's own editor law); /chat/new's pick
chip still says "from the map".
Tests: rendering in factory/sanitize/parse/resolve pins, the GraphSection
render pins (Extraction label + rendering row), the home-variant
chain-table pin (no close X). 1414 pass; tsc, lint, build green.
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.
Root cause of 'doesn't register': the slice-6 floating-bar edit never
landed (a silent no-match replace) — the Body accepted selectMode but
the bar ignored it, so the picker showed Clear + Delete and nothing
ever confirmed. Found by re-reading; the test suite never pinned the
select-mode bar.
The owner vision instead: the chain table's selection is PERSISTENT
and caller-owned.
- ChainTableOverlay gains controlledSelection/onSelectionChange (every
check, clear, and delete-prune reports up immediately; uncontrolled
fallback keeps the delete flow self-contained).
- Select mode's floating bar: Done (closes; the pick already
registered) — the delete fence never renders while picking.
- GraphView threads the lifted set through, resolving ids → nodes
against the live snapshot.
- Home: the pick bar above the composer shows 'N propositions
selected' + Clear in EITHER mode (dashed 'Pick propositions from the
map' hint only in practice mode with nothing picked); visible hover
(bg-accent) so the chip reads clickable. Practice sends still seed
from the pick set.
- 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).
- Sidebar: the three-way kind filter (Teaching/All/Practice, persisted
in localStorage) above the search; two new-session doors (Teaching →
/chat/new, Practice → /chat/new?mode=practice); practice rows carry
the dumbbell badge and 'Practicing…' busy meta.
- Draft: ?mode=practice swaps the copy (title, empty state, 'What do
you want to practice?') and startDraftSession posts kind:'practice'.
- Graph entry (home composer): teach|practice switch on the stats row's
left edge (StatsBar leadingSlot); practice mode shows the propositions
chip that opens the chain table as a picker (its floating bar becomes
'Practice these' — no delete fence); the picks seed the opening prompt
('Propositions from the map:…') while the title stays the typed text.
Consistency ruling (owner, 2026-10-01): the finish-first send and the
run-end focus are properties of the COMPOSER, not of one page.
- home (graph view, raw textarea): topicRef mirror; start() finishes
dictation first (before the setup/key guards, so an intercepted draft
is the complete one) then reads the mirror; the start square stays
live while a run holds deferred speech; run end focuses the topic
input.
- new-session: the shell owns the dictation instance — handleSend wraps
the parent's send with finish-first, the composer stays sendable
during a run, and run end focuses it via the Composer's inputRef. The
parent's send reads a textRef mirror (applyText at every write): the
flush lands via setState after the shell's await, and the parent's
closure must not read a stale draft.
The reported bug (2026-09-28): every chat ran glm-5.3-flash regardless of
any pick, while composer and settings UIs agreed with each other and lied
about the run. Root cause: a fossil default-settings record (settings.json
chat section, frozen pre-slots-wave) was stamped verbatim into every new
chat at birth by the new-session flow, and resolveConversationSpec prefers
the per-chat record over the strong slot forever.
Owner redesign — models are per session, always; the strong slot is the
new-session default:
- POST /api/chats stamps the newborn verbatim from the strong slot
(model + thinking level); no client settings PUT on create anymore
- the composer control is dual-bound: in-session it reads/writes the
session's own record (GET /api/chats/:id, PUT .../settings); on the
draft surfaces it binds the strong slot (picking there = changing the
default)
- thinking levels follow the identical mechanics (confirmed by owner)
- the zombie default-settings system dies whole: useDefaultSettings,
/api/settings/defaults, src/store/default-settings.ts, the chat
section of UserSettings (sanitizer strips fossil copies), the legacy
default-settings.json fold, and DEFAULT_SETTINGS_FILE
- catalogDefaultsFor collapses to the strong slot alone
- thinking display for a legacy unstamped session resolves exactly like
the engine (session ?? strong ?? model ladder)
Tests: new chat-birth-stamp suite pins the stamp, the unconfigured boot,
the unset level, and the copy-not-live-view regression; defaults pins
rewritten strong-only; legacy-migration suite deleted.
Owner round 2026-09-25, over 09c0f6e. The wave's tooltips read as
distracting; this round makes them quiet:
- Delay: TOOLTIP_DELAY_MS = 500 in the primitive — tooltips appear when
you pause on a control, never in passing (Radix focus-opens stay
instant by design; keyboard users don't wait).
- Vanish on leave: disableHoverableContent — the chip is un-hoverable,
so the instant the cursor leaves the trigger it's gone, even mid-move
onto the chip's own pixels.
- Look: bg-accent (#2a2a2a, the hover-chip tone) instead of the white
bg-foreground slab; 11px; px-2 py-1; arrow culled (nothing purely
decorative); text-foreground/85.
- Suffix: parentheses, not em-dash — "Dictate (⌘D)"; the registry
source unchanged (still override-aware).
- Drops (owner-selected): send square, start square, stats summary —
the icons/numbers describe themselves.
- Home logo kept but to the RIGHT with its real shortcut "Home (⌘G)"
(jump-graph routes to /, the same destination).
- Trims: "Model selector (⌘K)", "Thinking level", "Graph costs —
click for details", "How much of this session isn't mapped yet".
- Added: Import Notes gets "Import notes into the graph" — the one
button whose destination wasn't obvious.
Pins: TOOLTIP_DELAY_MS=500; hintText parens expectations updated.
Live-verified on :3001 — 508ms hover delay measured, close within 10ms
of pointerout, chip styles probed (rgb(42,42,42), 11px, 4px/8px), arrow
gone, all new labels + sides confirmed, drops carry no tooltip and no
aria-describedby.
Owner-approved full pass (tooltip wave, 2026-09-25). Mechanism: icon/pill
controls ride the styled Radix tooltip via a new Hint composition
(components/ui/hint.tsx) — the shared primitive adopted as-is, no
restyling; the shortcut appends as an em-dash suffix off the LIVE registry
(a rebind in Settings → Keyboard changes the suffix): "Dictate — ⌘D".
Surface-owned keys (Esc closes, Enter submits) ride a raw binding prop.
Native title= stays only for truncation-reveals (dock spans, the rename
field) and menu-interior abbreviations (MenuShell untouched). One
em-dash pattern; per-state truth on the send square (busy = "Stop the
reply — Esc", idle = "Send — ↵"), Enter on the plan verdict's accept,
"Stop dictation (Esc)" kept verbatim per the owner's flag.
Copy: the dev-speak cull — no pipeline/prober/tier/wave vocabulary
anywhere a user reads. New pins in tests/tooltip-mechanism.test.tsx
(hintText composition, asChild no-wrapper-DOM, the auto-update hint
constant); dock truncation titles pinned native; graph-chrome + settings
pins updated to the new copy.
Live-verified on :3001 — 12.6ms hover appearance (no native 1s lag);
glyphs render on every suffixed surface (⌘D, ⌘K, ⌘⇧F, ⌘,, ⌘B, F2, ↵,
Esc); per-page probes confirm Settings entry, Home logo, session search,
Start session, Close sidebar, model + thinking pills, stats summary,
rename title, plan chip, coverage ring, send square, cost button, node
search (⌘F), graph gear, settings close (Close — Esc), keyboard section
"Fixed — part of this screen", auto-update hint, light-mode "Coming
soon", the three slot rosters, graph-tools hint. Esc still closes the
settings dialog.
The owner's asymmetry find (interlude over the zero-keys wave): the
models-unconfigured case guards BEFORE send — no request, no chat
created, setup opens — but the key cases only reacted to the 503 after
POST /api/chats had already created the record, leaving orphan error-shell
chats in the sidebar. The guards now twin the models mechanism on BOTH
creation paths (home start(), /chat/new send()):
- Zero keys (useZeroKeys reuse): no provider key present -> skip creation
and send entirely, open SetupDialog (stage 1 first-key screen).
- Strong-provider key missing (owner-approved extension): keys exist
generally but the strong slot's pinned provider has none — the original
deleted-key scenario. New pure strongKeyless(catalog) in setup-cta.tsx:
slots.strong resolved pin + providers[] (present-key only, the catalog's
own federation surface), false when unconfigured (the models guard owns
that case) or catalog not loaded (the server 503 gate remains the belt).
useStrongKeyless rides useModelCatalog, re-reading on the 'keys' AND
'models' signals (a deleted key or a re-pinned slot flips it live).
Both guards run after the configured check, same
skip-everything-and-open-setup treatment; 'force' (setup's onDone replay)
bypasses both — completing setup implies a keyed provider. /chat/[id]
sessions keep the 503 revert-draft interception unchanged: those chats
legitimately exist.
Pins: strongKeyless fires on a keyless strong pin (keys elsewhere or
none), never fires with the pin's key present (incl. the keyPresent=false
belt), false on unset pin / unloaded catalog. Normal-path pins ride the
existing startDraftSession contract suite. Live-verified on :3001 under
LH_IGNORE_ENV_KEYS=1 with a file-key anthropic + openrouter-pinned strong:
both guards on both pages (setup opens stage-1 / stage-2 respectively,
draft preserved, 154 chats unchanged, zero sidebar entries), normal path
with a keyed strong provider still creates and lands the prompt redirect.
929/929, tsc/lint/build green.
Over Platform's 66dbea9 key-presence seam, the five owner-locked tasks:
1. Zero-keys pill — components/setup-cta.tsx: pure hasProviderKey
(classifyKeys reuse — tool keys like Deepgram never count), useZeroKeys
(GET /api/keys, re-read on the new lh:settings-saved 'keys' signal),
ZeroKeysPill (testid setup-cta-keys) taking PRECEDENCE over the models
CTA on chat/home/new-session. SettingsSection gains 'keys'; keys-section
dispatches after save AND delete.
2. Setup stage 1 is self-contained: provider picker (MenuShell +
ProviderMenuList) + key paste + Save via PUT /api/keys/:id — the dialog
STAYS MOUNTED; its own save dispatches the keys signal, the fetch effect
re-runs on it, and the stage flips to the pickers on its own.
onOpenKeys + setup-open-keys die. SetupKeysBody exported for SSR pins.
3. parseProviderKeyRefusal (chat.tsx, envelope-verbatim twin of
parseModelsRefusal) joins the revert-draft-and-open-setup interception;
activity-dock reads 'needs a provider key'; dispatch-card shows
'Add a key' — both deep-link setup, which lands on stage 1 by itself.
4. Dictation trio: the token route's only 503 (missing Deepgram key)
becomes the client-authored DICTATION_KEYLESS short line; the errored
idle click clears the error and deep-links Settings -> Keys ->
DEEPGRAM_API_KEY via the new open(section, row) seam (dialog landOnRow
-> SettingsDialogBody initialRow -> KeysSection openRow follow-effect).
Live-verified on :3001 under LH_IGNORE_ENV_KEYS=1 (the fresh-user switch):
pill on all three surfaces + precedence over the CTA, stage-1 save ->
auto-advance with dialog mounted, real 503 send refusal reverting the
draft and opening setup, dictation 503 -> short line -> Settings lands on
the unfolded Deepgram row with the error cleared, keys-section save and
delete both flipping the pill live, and a fabricated refused research job
rendering the 'Add a key' dispatch card. 926/926, tsc/lint/build green.
Part 1 — the surface:
- Settings ▸ Agent ▸ Tools gains the prober GRAPH-TOOLS row as its FIRST
row (owner ruling: in the Tools section, not the tool-toggles list —
its subject is the map, its mechanism is agent capability). Writes
agent.graphTools {enabled} (absent = on, the toggle discipline) via
the section PUT; composeGraphTools pure seam. Its own key in the agent
contract — never in the tools map.
- The row carries the search-row hint discipline: "Connects prior
sessions' knowledge into new ones — the prober reads the knowledge
map" (owner wording). The honest interplay composes both: when
graph.enabled is off the row dims + disables with a "Graph is
disabled" hint (the effective gate itself is server-side, per-turn
fresh). AgentSection reads the graph section (record.graph, passed by
the dialog) — read-only.
- Cluster labels wrap: wave 7 made labels session names and FILE PATHS,
which the old single-line fillText could not bound. wrapRegionLabel
(pure, exported): word-wrap first, char-split long paths (the
node-label discipline), capped at 3 lines, overflow folded into an
ellipsized last line (owner: wrap, cap 2–3, ellipsize). Pre-wrapped
once per geometry build at the SCREEN-fixed size (viewer-relative
labels — the wrap never goes stale mid-camera-move), drawn centered
line-by-line at the centroid. Deleted-session clusters keep their
hull-only honest silence (label null → no lines).
- The orphan sweep: StatsBar's leftSlot prop is dead (its one consumer,
the knowledge-context slider, died in c690181) — removed, and pre-chat
views now render NOTHING on the left (owner ruling this round: a
"— · —" summary over an empty popover is pure noise) — the dictation
middle just widens. Stale knowledge-context comments swept in
chat.tsx (adoption-window + activity-nudge docs), activity-dock.tsx
(useActivity ground rules), dictation.tsx (×2 adaptive-meter docs),
home.tsx (pre-chat dock comment).
Part 2 — Teacher's c690181 review: clean. Imports, KIND_ICON/KIND_LABEL
entries, render branches and event seams all excised whole; the probe-
handoff branch re-indented intact and merge-adopted; tests updated in
lockstep (merge-adopted, record-adapter, render-new-session retired).
Platform's 4b60e0f roster-string fixes (labeler dropped from both
SLOT_META blocks) reviewed — consistent across agent-section +
setup-dialog.
Gates: tsc clean, 854/854 (8 new: wrapRegionLabel cases, graphTools
SSR rows ×3; stats-bar + ladder fixtures updated to the new rulings),
lint 0, build ok. Live on :3001: graphTools row first-in-group with
hint, off→{enabled:false}→on round-trip, graph-off dimming + hint +
disabled toggle, pre-chat rows summary-free, chat view keeps its
summary, long-title cluster label wrapped without console errors
(visual read unavailable this session — pure wrap is unit-pinned).
The owner's zero-configuration ruling (2026-09-23): nothing configures
the graph beyond chat models. The prior-knowledge injection — its budget
dial, its runner, its marker part, its dock/dispatch entries — is
removed across all bands; the prober now reads the learner's persistent
knowledge map on demand through two gated tools instead:
- list_sessions: every birth session, names + kinds + counts + dates
(graphSessionIndex, Platform's core seam)
- list_propositions(session): what was born there + the session's own
latest understanding level + that evaluation's date
(graphSessionPropositions) — names/levels/dating ONLY, no statement
text (owner ruling: the map's organization is the prober's business,
its prose is not)
Registered via createProberTools when chat-handler passes graphStore
(the graphToolsEnabled gate decided server-side, per-turn fresh); the
prober doctrine gains the map-review nudge at session start.
Also: runner's JobKind special-casing collapses (KIND_ROLE/KIND_RUNNERS
are plain records again), semantic-clusters.ts dies with its test, the
embedder dep's doc tells the wave-7 stub story, and ports.ts's
readClusterLabels/readNamingRuns surface stays untouched for Platform's
ledger-port interlude.
848/848 tests, typecheck/lint/build green.
Item 1 — no Default in the slot selectors (owner, fix wave): a
"default" model is not a thing in this app. Picking Default used to
delete the slot and re-arm the first-run gate — incoherent. Now the
model menus carry NO clear row at all (a slot holds a pick or reads
"—"), the thinking menus carry a "—" row (menu-none) that clears only
the thinking pin, and the hint line is the roster only — the resolved
factory pin is never named. Master's amendment confirmed: the
factory-pin hint is SUPERSEDED entirely (Platform removes the pins).
Item 2 — the composer control IS the strong slot (owner: "one and the
same"): ModelControl (model-picker.tsx) reads the raw models section
(GET /api/settings) and the federated catalog, and writes
PUT /api/settings/models via composeSlotModel — the same seam the
settings Agent section and SetupDialog use. Props retired: chatId,
settings, onSaved, fallbackModelId, noDefaultModel — the control is
self-sufficient and identical on every surface (composer, home dock,
/chat/new). The per-chat model PUT is gone from the UI; legacy
per-chat overrides keep resolving server-side. StatsBar/DockOverlay
plumbing slimmed accordingly; chat.tsx drops its per-chat settings
state and initialSettings prop.
Item 3 — the composer catalog cache no longer freezes per page load:
fetchCatalog(force) invalidates, and every model-menu open revalidates
in the background (stale-while-revalidate — cached list shows
instantly, the fresh federation swaps in). Owner's repro verified live:
a key saved mid-session widens the menu without a reload.
Item 4 — stale doc comments fixed: model-catalog.ts's "OpenRouter
catalog"/"multi-provider future" (Platform's file — mechanical,
flagged for review) and model-picker's retired "config-pinned"/
per-chat-PUT narrative.
Live-verified on 3001: unpicked slots read "—" everywhere; model
menus have no clear row; the "—" thinking row clears the pin but
keeps the model; composer pick writes strong and preserves cheap/
vision siblings; thinking pill writes strong.thinkingLevel; groq key
added mid-session appears in the open menu without reload. Caught in
live verification: the record fetch was mapping the WHOLE settings
record into the models section (picks never wrote) — fixed to read
body.settings.models.
Gates: typecheck, lint, 807/807, build.
Chunk B (owner-designed, model-slots wave) on the merged engine surface
(main 1d66a17):
AGENT SECTION — SLOTS ONLY (owner ruling)
- The six per-role model rows are GONE; three slot rows instead:
Strong (Prober + Teacher), Cheap (five workhorse roles), Vision
(visual maker + PDF reader), roster + resolved-default in every hint.
- Slot dropdowns share the app's menu language over the FEDERATED
catalog (/api/models = keyed providers only, fresh per call — saving
a key in Keys immediately widens the picker); the vision slot
filters to image-capable models (Model.input); the menu's highlight
now matches provider+id (ids can collide across providers).
- Slots write the new models section (PUT /api/settings/models) through
the dialog's write seam; per-role overrides stay schema-only.
- ModelMenuList rows read 'provider · id' — federation makes the
provider bookkeeping-relevant. Usage stamps render provider-qualified
(prettyModel(qualified): 'Glm 5.3 Flash · openrouter') in the stats
bar's turn lines.
SEARCH ENGINE (search wave: no default, owner)
- A row in Tools: Tavily/Brave via the shared-menu look, Automatic =
the pin removed (auto-activation). The live reason line comes from
/api/search; no engine key at all grays the whole row + disables the
trigger (a keyless choice would only block auto-activation).
FIRST-RUN SETUP FLOW (owner design A: composer CTA + send interception)
- Chats cannot start until all three slots are picked — no defaults
for 33 providers (slotsConfigured: all three slot models required).
- The graph view's new-session dock (home) shows a 'Set up your models'
CTA while unconfigured; submitting a topic opens the SetupDialog WITH
THE DRAFT PRESERVED; Save stores the models section and the queued
message sends. Same interception on /chat/new sends.
- STAGED BY DEPENDENCY (owner: keys first, models after): no keyed
provider → stage 1 deep-links the settings dialog on Keys (open now
takes a section); a saved key reopens at stage 2 on the next submit.
- Stage 2: Strong → Cheap → Vision pickers (federated, vision-filtered,
all three required). Closable without configuring — browsing stays
possible; the gate is the send, not the dialog. Layered Esc: an open
slot menu eats Esc before the dialog.
- Two closure bugs caught live: onDone→start/send captured the stale
pre-save 'configured' (the flow now forces the replayed send); menu-Esc
used to close the whole dialog.
Settings-dialog provider: open(section?) lands on a section (stage 1
deep-link). Tests: composeSlotModel/composeSearchEngine pure, slot SSR
replacing role rows, slotsConfigured/setupStage first-run gates,
provider-qualified prettyModel. Gates: typecheck, lint, 792/792, build.
Owner reframe (2026-09-18): the model + thinking + context controls on
the home graph view and /chat/new are not a draft overlay on a baked-in
default — they ARE the settings page for the default model, and the
user's last choice IS the default. BYOK first boot has no keys and
possibly no OpenRouter, so there is NO default to show: the controls
render 'no model' ('—') until the first pick.
The flash was the deeper symptom: the surfaces rendered from client
state that started empty and fetched truth afterward, so every visit
flashed the config pin (GLM/low — a dev artifact) for a few frames.
Fix at the root: both pages are now force-dynamic server components
that read the record (readDefaultSettings → initialSettings) and hand
it to the client — the first frame shows truth. Dynamic routes aren't
cached client-side (staleTimes.dynamic = 0), so every navigation
re-reads the record; the useDefaultSettings hook keeps only save-side
state (optimistic set + PUT). The GET-on-mount and its touch-guard are
gone.
ModelControl gains noDefaultModel (the default surfaces only): unset
settings render no model/level, never the catalog pin; the thinking
menu no-ops until a model exists. Chat surfaces keep the catalog
fallback — the engine runs the config pin when a session record has no
override, so the control keeps showing what will actually run.
Renamed draft→default throughout: data/default-settings.json,
GET/PUT /api/settings/defaults, useDefaultSettings. New sessions
still inherit the default on creation exactly as before.
Live-verified: first-boot 'no model' with zero flash, picker +
Shift+Tab cycle, values held across session→/chat/new→home roundtrips
and a reload (10×100ms samples, never the old default), zero console
errors.
Both new-session pages (the home graph view's topic dock and /chat/new)
held their model + thinking + knowledge-context choices in plain
useState(undefined) — every navigation reset them to config defaults.
Now both surfaces read/write ONE server-side record
(data/draft-settings.json via GET/PUT /api/settings/draft, the
render-settings pattern): whatever the learner last left the controls on
is what every later visit shows. useDraftSettings loads on mount with a
touch-guard (a slow GET never clobbers a fast choice), saves
optimistically. Session creation still carries the choice into the new
chat exactly as before; per-session settings are untouched.
The PUT validation is the exact per-chat contract — parseSettingsBody
extracted verbatim from app/api/chats/[id]/settings and shared by both
routes (unknown model/level → 400 with the supported list, never a
silent clamp). 400s on garbage, {} = the clear-overrides write.
Live-verified: Cmd+K+Enter model pick, Shift+Tab thinking cycle, context
slider — all held across home → session → home → /chat/new, and carried
into a created session's record.
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.

Two-band architecture from docs/research/stt.md: renderer captures mic
audio in an AudioWorklet (linear16 16kHz mono, ~128ms frames, per-quantum
RMS for the meter) and streams it directly to Deepgram over WebSocket —
audio never loops through our server. The real key stays server-side;
/api/stt/token mints a short-lived grant token (TTL 300s) per run.
Patterns ported from the owner's pi dictate extension (tuned in real
use): generation counter guarding every async handler, the
latest-RMS-never-resets meter (-50..-10dB window, 60ms tick), mic-first
stop + CloseStream + 3s safety net, endpointing=300 with the
utterance_end_ms=1000 backstop.
UI (owner placement): mic button in the stats bar's middle slot on all
three surfaces (home graph-view, chat, draft); while recording the meter
unfurls to fill the row's free width with the interim ghost at its
flank. Esc ends dictation from the composer. Token mint comes before
getUserMedia so a keyless app fails fast without a TCC prompt; one
automatic reconnect on abnormal socket close, errors surface inline.
Live-smoked the full error path in the dev shell (bar renders on all
three pages, 403 grant failure shows inline, mic untouched). The full
audio path needs a Deepgram key with Member permission to mint tokens.
The home header carried -webkit-app-region: drag after <main> in the
tree, re-adding drag over the graph chrome row's no-drag carve-out —
Electron's mask applies carve-outs only to regions added EARLIER in the
DOM walk, so the gear/search/coverage/import buttons dragged the window.
Fix: a dedicated 52px drag-mask div placed FIRST in the home page DOM;
every carved control (chrome row, node detail card, toggle) comes later
and subtracts correctly. The header loses its app-region entirely — the
mask routes the pixels, the header stays a pure pointer-events container.
Retires the .lh-float-drag CSS class.
Verified live in the Electron dev shell by the owner: chrome row,
sidebar close button, logo, and window drag all work.
The system title bar disappears (titleBarStyle hiddenInset +
trafficLightPosition {16,24}): the app's own 60px header bands become the
window's drag surface, and the traffic lights float over the sidebar's
mark band, vertically centered on the same line as the chat header's
phase pill (pixel-verified: circle centers y 24–36.5pt, pill box center
30pt).
- electron/main.cjs: hiddenInset chrome; dev shell (LH_DEV_URL) gets its
own userData (-dev suffix) so it never fights the packaged app's
single-instance lock — verified: the lock silently killed the dev
shell while the packaged app was open (that also proved the lock works
across separately-launched builds).
- app/globals.css: .lh-electron-gated utilities — drag/no-drag bands,
92px traffic-light gutter (.lh-lights-gutter / .lh-closed-toggle:
lights end ~75pt + the lights' own 16px edge inset as the gap),
home's floating strip becomes a drag surface only in the shell.
Everything is inert in the plain browser.
- sidebar.tsx: SidebarProvider sets <html class=lh-electron> post-mount
(UA detection; no hydration mismatch, absent in browser); LH wordmark
text replaced by the owner's mark (components/lh-mark.tsx, inlined
icon-no-padding.svg, 24px, home link kept); SidebarToggle gains the
92px margin when closed so it never slides under the static lights.
- chat.tsx: the rename hit-box shrinks to the title text itself —
flex-1 spanned the whole bar, so every click started a rename and the
window lost its grip. Shrink-to-fit + a flex-1 drag spacer (chips stay
right) + hover:bg-accent affordance (clear when hover renames vs
drags; -mx/px cancel for zero shift). The renaming input keeps flex-1
for edit room.
- home.tsx / new-session.tsx / phase-divider.tsx: drag bands + carve-outs.
Live-verified in the dev shell (pixel analysis) and headless browser:
lights/pill/mark centered, 17pt lights→mark gap, rename click→select-all
→Escape roundtrip, browser layout untouched.
Gates: typecheck, eslint, 500/500 tests, build.
- 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.
The original vision, restored (owner, 2026-09-15): pre-chat the session-
data side of the under-composer stats bar is free real estate ("—" only),
so the budget slider mounts exactly where session data will sit once a
session exists — via a new StatsBar leftSlot — vertically centered with
the model + thinking pills by the row's own geometry. Short 96px slider
instead of a full-width one; readout abbreviates "1k tok" so >1k budgets
stay on one line ("4.1k tokens" wrapped). Home and /chat/new both.
One shot per chat, fired at the first turn's onFinish: the session's
topic (its only typed message) is embedded as an EmbeddingGemma retrieval
query; the semantically closest graph propositions are selected under the
session's token budget (pure budget, no similarity threshold — the
decided doctrine) and delivered as a marker-only steer through the wake
pipeline, queuing behind pending questions like every sub-agent result.
- contracts: ChatSettings.graphContextTokens (default 1024, max 4096,
step 128, 0 = off); GraphContextData + graphContextText; the
graph-context JobKind + buildGraphContextSteer (id steer_ctx_<chatId>)
- core/graph-context.ts: brute-force cosine top-K, greedy chars/4 fill
under budget, most-recent UnderstandingLevel fold, count cap 64,
parse-don't-cast at the marker seam
- server: embedQuery (role-asymmetric query format, same warm singleton
— vector-space parity by construction); the runner (startGraphContext-
Injection one-shot gates; runGraphContextJob validates ledger parity);
wake branches (chatIdOf/jobIdOf, finalizeJob done, recoverStaleJobs
re-deliver or contextRespawn); abortJob kills context jobs SILENTLY
(nothing was promised in the lesson); turn-service trigger seam
- adapter: data-graph-context flattens to the canonical block (malformed
parts have no model face)
- UI: the budget slider (home dock + /chat/new draft, the session-data
strip); the quiet SystemLine "~537 · 10 propositions"; dock kind
"Knowledge context"; model-picker PUT now spreads settings (a model
pick can no longer clear the sibling override)
Live-smoked end to end on the real embedder + real GLM: seeded ledger
(10 propositions), session on "modal logic: possible worlds and the
necessity box" — job in the dock, queued behind the prober's question,
delivered on the answer, SystemLine in the transcript, wake turn reads
the block and continues the probe. Gates: tsc, lint, 459/459, build.
The rhythm agreed with the owner: the stats/controls row hugs the
composer (8px — reads as the card's metadata, one object), and the
whole cluster floats with deliberate air above the screen bottom
(20px). The 8px straight-edge gap optically matches the 6px pill-to-
pill gap: two rounded pills' corridor reads wider than geometric, so
rounded-rounded gaps run ~2px tighter than straight-edge gaps.
- stats-bar.tsx: pt-4 -> pt-2 (8px under the composer) — shared by
chat and home automatically
- chat.tsx dock block + home.tsx composer wrapper: pb-4 -> pb-5
The dock's reserve auto-measures the block, so the spacer/fold
machinery adapts on its own.
The home graph view had breathing room on every side (main px-4 py-2,
the composer docked below in flow, the header above). Per the owner:
- The canvas now owns the whole column — absolute inset-0, from the
sidebar to the right edge of the screen, bottom to top, zero padding.
- The header floats over the graph (pointer-events-none except the
sidebar toggle, so the canvas stays draggable around it).
- The new-session blob + stats bar dock OVER the graph at the bottom,
no gradient scrims anywhere — the graph runs clean under everything
to the very edges.
- The renderer itself is untouched: same canvas, same data, same fit
logic — only its container grew. The composer keeps chat's DOCK
geometry (max-w-[46rem] px-4) so nothing shifts when a session starts.
Verified live in headless chromium (1280×800, sidebar open): canvas
spans x 288→1280 (sidebar edge → right edge), y 0→800 (bottom to top);
the header overlays the top; the dock overlays the bottom with its
content ending 16px above the viewport edge.
- ✓/✗ 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.
Sidebar (replaces the modal drawer):
- Inline, toggleable, no backdrop/focus theft — can stay open while working
- Open state persists across pages (provider in root layout) and reloads
(localStorage; starts closed server-side to avoid hydration mismatch,
stored value applied post-mount; default open on first run)
- Hamburger in page headers only when closed; close button in sidebar header
Floating composer blob (per reference screenshot):
- Floats over the transcript (absolute overlay), persists at bottom while
scrolling, content fades behind it (gradient mask); pb-44 scroll clearance
- Concentric corner radii: blob rounded-2xl(16px) − p-1.5(6px) = send
rounded-[10px] = 25% of the 40px button; CornerDownLeft icon per reference
- Stop moved from header into the blob (busy → square icon)
- prompt-input.tsx + 7 orphan ui files pruned (attachments/command palette
unused); hand-rolled Composer is ~100 lines and render-tested
Pending-question morph (one text field on screen, never two):
- Quiz/ask-select pending → blob becomes the note field (send hidden, hint
line above); card's internal note input removed; Submit consumes it
- Ask free-text pending → blob becomes the answer field; its send submits
via the card's registered submit api (ref bridge); Enter works
- Chat owns the single text state; card clears it on submit
- canSend for answer mode mirrors the card predicate directly — reading the
ref during render lagged one commit (found in browser testing)
Widths: one shared column (max-w-3xl + px-4) for transcript, cards, and
composer — all three measured pixel-identical (left 416, width 736).
Assistant Message max-w-full/MessageContent w-full (was max-w-[95%]/w-fit —
the 'cards are a bit shorter' bug).
User messages render plain text again — no math pipeline on learner-authored
text (currency hazard accepted for the model only, guarded by the prompt).
Tests: 58 pass (5 new composer pins; card tests updated to controlled
props). Verified live: note flow, answer flow, sidebar persistence, float,
fade, zero console errors — plus the live model spontaneously honoring the
$ currency escape contract in a continuation.
Layout:
- Home = knowledge-graph placeholder (main view) with new-session input
docked below; session list moved out of home into a hamburger drawer
- SessionDrawer: slide-over session navigation (backdrop/ESC close, active
highlight, fetches /api/chats on open) on both home and chat headers
- Chat header loses the back button — the drawer is the navigation
Math (inline $ was silently not rendering):
- @streamdown/math defaults singleDollarTextMath:false — now
createMathPlugin({ singleDollarTextMath: true }) in message + reasoning
- katex.min.css imported in layout (streamdown does not inject plugin
styles; display math only looked right via browser MathML fallback)
- QuizCard/AnsweredCard route question/options/explanation through
MessageResponse; user chat bubbles render markdown+math too
- Currency hazard: micromark-extension-math@3.1 lacks pandoc's
closing-digit rule, so bare '$5 and $10' parses as math — defense is at
the source: system prompt now instructs escaped \$5 / 'USD' for money
Hydration fix (React #418):
- QuizCard shuffled options with Math.random() — server/client orders
diverged. shuffleOptions now takes an injectable RNG; QuizCard passes
seededRandom(toolCallId) (mulberry32/FNV-1a in question-core). Same
question → same stable order across reloads; still varies per question.
Tests: 53 pass (5 new math-rendering pins incl. fenced-vs-one-line $$
behavior and the escaped-currency contract). tsc + next build clean.
Verified live in browser: inline/display math in text + cards, drawer
open/navigate/active-highlight/ESC, no console errors, no font 404s.
The teaching agent no longer runs on pi. Stack:
- ToolLoopAgent (ai@7) + OpenRouter (OPENROUTER_API_KEY), model via LH_MODEL,
default anthropic/claude-sonnet-4.5 with reasoning tokens
- quiz/ask_user_question = client-side tools (no server execute): the call
lands as a typed tool part in input-available state; the card grades via
src/core/question-core.ts; addToolOutput sends the verdict; the teacher's
reaction continues the same assistant message
- resume-mid-quiz is free: the pending tool part persists in the transcript
- persistence: one JSON per chat (data/chats/), full UIMessage transcripts,
saved onFinish (also on abort)
- UI: AI Elements (owned copy-paste components, pruned to the five in use)
+ button-based QuizCard/AnsweredCard (ask answers never graded)
- pi fully removed: TUI, extensions, Fastify+WS server, bridge, custom
protocol all deleted (recoverable from git history)
- tests: question-core units carry over; chat-flow integration drives
handleChatRequest with MockLanguageModelV4 (48 tests, zero tokens);
render smoke tests guard the cards (renderToStaticMarkup)
Carried over unchanged: teacher system prompt, question-core, schema/
ledger/derive/extract pipeline, data model.
