"The model selection in teach it back is kinda broken at least on desktop":
the desktop panels were position:absolute children of whatever container held
their chip. In chat that is the composer at the bottom of the column, which
works, but Teach it back keeps its chips inside a scrolling form card — so the
panel opened upward out of the card and its top rows (including the selected
model) were cut off. The probe measured top: -66px and no way to reach the
first rows by scrolling the list.
- New components/chat/PickerPopover.tsx: the desktop surface for both pickers,
portalled to <body> and position:fixed, anchored to the opening chip
([data-picker-trigger][aria-expanded="true"]), opening on the side with room
and capped to the viewport so the panel scrolls as a whole with its heading
and note attached. It closes on an outside press, Escape, resize or a page
scroll — but not on scrolling its own list.
- ContextPicker and ModelPicker use it on desktop; the phone sheets and their
inner list caps are unchanged (the list max-height became a parameter: the
sheet caps it, the desktop panel scrolls instead).
- teach-test pins it: the panel's rect is fully inside the viewport,
elementFromPoint over it lands on the panel, it is not a descendant of the
scrolling card, and picking a model updates the chip + freezmo.chat.model.v1
(46 checks). Chat and the phone sheets re-verified unchanged (110 + 128).
Version 0.8.3, SW v105.
"Terribly high CPU usage, the MacBook gets really hot" - a fanless MacBook
Air on a 144Hz screen. Measured on that machine with headed engines
(process CPU plus the per-process GPU time macOS keeps): an idle Aero
library cost LibreWolf ~110% CPU and ~230ms/s of GPU, the study feed ~130%,
Chromium up to ~57% CPU and ~350ms/s of GPU, Safari ~220-250ms/s of
WindowServer GPU. Priced one by one:
- the gradient mask on .ice-floats re-rendered the animated layer offscreen
on every frame (~75 points of Gecko CPU). The floats now rise through a
plain rectangular band clear of the header, the bottom chrome and the
rail, and fade in and out inside it, so the clip never cuts a visible one;
- the overlay grain forced a backdrop readback per frame for a texture that
measured a mean <=0.11/255 difference: removed;
- the invisible blob drift made every frame a full-screen redraw: the blobs
are painted once;
- static glass (answer tiles, feedback panel, chips, inputs, dropzones,
lists, segmented controls, Aero hint chips) re-blurred the moving scene
every frame: only floating glass blurs now, and Aero's baked chat chrome
drops a live blur that never showed under the bake;
- the scene also parks while the window has no focus and under any dialog
or sheet scrim (.scene-pause); the loading icon is a compositor-run CSS
animation instead of a framer-motion main-thread loop.
After, focused and animating: LibreWolf library 109% -> 33% CPU, study
134% -> 34%, chat 130% -> 42%; Chromium GPU 2.5-4.4x lower with 7-22 points
less CPU; Safari's WindowServer GPU -20-26% in Aero, about half in dark.
Unfocused or under a sheet: nothing. bubbles-test sweeps every float through
41 phases against the band and pins the parking and the cost contract;
tests/heat-probe.mjs (macOS) repeats the measurement; the suites find
Playwright's Chromium on macOS.
All 15 suites pass, lint clean, the contrast scan lost a finding. Version
0.6.7, SW v89.

The header and composer were full-bleed bands (flush to the top/right/bottom
viewport edges, composer corners off-screen) next to a rail that floats with a
12px margin. The new --layout-gutter (12px) spaces the rail, header, empty-state
card and composer identically on every side; --radius-panel/-control/-chip
(-pill) replace the ad-hoc radii across the shared classes, so every panel is
rounded on all four corners and shared controls match in every theme. The
desktop-only ::after hairlines and the left-corner-only radius are gone.
Aero: the rail and the chat chrome (answers included) share one even recipe -
the wallpaper extra-blurred into a hue-free wash (background-glass.webp) under a
uniform ~50% white veil and a whisper of gloss. Measured within ~10 RGB units
across the rail top->bottom and the card/composer left->right; the blue->green
smear and the teal composer are gone. The composer's field is a clean even tile
with no wallpaper gradient inside it.
Chat fixes: send is a filled primary tile shaped exactly like attach (dimmed
while the input is empty), suggestion/context chips use the shared .chip token
(40/44px target, visible rim, full-contrast text, raw model id in the tooltip),
the AI note reads at 12px --text-muted (.ai-disclaimer), the selected sidebar
row carries the accent border + accent icon, the theme toggle is back in Aero
(the moon flips to Dark; Settings brings Aero back), and the empty state is
centered exactly between header and composer.
Outside CSS: the wallpaper's top-left HUD-circle decoration (it peeked through
the 12px gutters on wide windows) was healed out of background.webp and
background-blur.webp; the orbs/bubbles ride one masked .ice-floats layer that
fades them under the chrome bands and the rail strip, so none is sliced by a
panel edge (still parked under reduced motion).
Version 0.6.0, SW -> freezmo-v82. Tests: chat suite pins the new geometry (12px
gutter, 24px corners, even wash on all four panels, send-vs-attach shape,
chips/input radii); mobile pins the phone chrome and the Aero toggle; bubbles
pins the floats layer + its reduced-motion opt-out.
Buttons: the recipe's thin veils let btn-secondary/btn-ghost/glass-pill
blend into the grass and sky - they now carry a stronger pale-glass veil
(the Ask-pill look) over the blurred scene, ghosts plus a rim and
full-contrast text. Homework make/check results gained the same red "!"
report control as the feeds and the guide (a synthetic short-answer
activity maps into the report flow; pinned in phase3).
Reduced motion: the manual toggle only fed framer's MotionConfig, which
strips transform animations - while components branched on the OS-only
useReducedMotion - so translucent sheets still spring-faded their opacity
in over the page (the "ugly visual glitch with the settings panel"). All
16 components now read useAppReducedMotion() (OS or toggle), and the
settings sheet/scrim and the library's phone sheet go instant. Verified
frame by frame: opacity 1.00 from the first frame.

- Aero: blue gradients back on the active segment and every primary
(Review due, the card's Study button, the composer's send button); a
frosted backing behind the page heading and the All decks label; a
bottom-weighted rail tint; chat header/composer/welcome panels; calmer
orbs; stronger card veil + a stronger blur bake.
- Dark/Light: a dedicated --track token makes progress bars read (the
first attempt shifted --surface-sunken and the pixel scan caught the
sheet-contrast regression); brighter dark secondary text; darker light
segmented labels and difficulty tints; stronger light card border and
shadow.
- Chat UI: friendly model chip ("Gemma 4 31B") with the raw name in a
tooltip, larger chips, plain centered disclaimer, vertically centered
welcome panel, distinct chat-plus icon for new chat.
- Chat models: every chat-capable model from the server's /api/tags is
selectable (favourites first, search field when long, live-list
validation in the route); default CHAT_MODEL_DEFAULT or gemma4:31b.
- Reduce motion: Settings toggle (default off) that parks the scene,
collapses CSS animations and drives framer-motion's calm mode.
- Folders hint, "New" badge on fresh decks.

Version 0.4.6, SW -> freezmo-v71.
Frutiger Aero (Settings -> Theme): a third theme, not a dark/light variant.
A sky gradient with a strip of grass, the glacier blobs become clouds, the
orbs soap bubbles, glass gets the classic horizon gloss and the buttons a
glossy aqua. The light/dark toggles (header, rail, chat header) hide while it
is on and the picker says why; the pre-paint script applies the class before
first paint and the PWA status bar follows (#3fa3e0). Its muted/frost text is
darker than Light's because those labels sit directly on the sky.
Contrast, measured on real pixels (tests/contrast.mjs, now covering aero):
- The light settings sheet was translucent over a dark scrim, so its muted
text measured ~2.8:1. Sheets and dialogs now use --glass-sheet-bg (a more
opaque surface), and Light's --text-muted is a touch darker.
- Result: 0 below-minimum findings and 0 axe violations across every screen,
all three themes, phone and desktop.
Also: the suites now seed the cookie notice as already dismissed (they run as
a returning user); the regression suite opts out to test the notice itself —
the previous deploy failed its gate because the notice blocked a chat chip
click. The notice also hides during immersive sessions (overlay-open), so it
can never cover a study feed.
Version 0.1.8, SW -> freezmo-v54.
UI batch from feedback:
- The study/review/exam/homework chrome is now a single 58px pill: round
close button, title + position over the progress bar, chips (or the exam
timer) at the far end — everything on the centre line, so nothing crowds
the rounded corners any more. Homework guide gets the same recipe.
- The immersive feeds carry z-[45] so they paint over the app chrome (on
/exam the header used to cover the top of the chrome), and the page chrome
behind an open overlay (.app-header, .segmented, .tabbar) is hidden while
the transparent overlay is up, so it can no longer ghost through the glass.
The guide's disclaimer moved inside the overlay with it.
- Chat: the context and model chips toggle their own popover (pressed state,
aria-expanded), opening one closes the other, a press outside closes it —
no more being forced to pick something to get out.
- Homework: the model's plain-text step explanations/hints/verdicts keep
their line breaks (whitespace-pre-wrap) — a step used to collapse into one
run-on paragraph with the whole solution inside it; the guide prompt now
says the explanation is coaching, 2-4 sentences.
- The four glacier blobs are at 25% of their old opacity (0.045 light,
0.1 dark).
Tests: phase-2 chrome geometry + exam layering checks (62), chat desktop
picker checks (101), the standing suites all green. README: decisions 54-56,
decision 23 updated. SW -> freezmo-v44.
- Conversations in a versioned IndexedDB store (freezmo-chat v1, zod
validated with the same schema backup/sync use, capped at 100 x 300).
Settled turns persist (question always; answer when produced, partial
stops included); ?c=<id> keeps reloads on the conversation via
history.replaceState (no router round-trip mid-chat).
- History UI: desktop column, phone sheet (spring, backdrop, Escape),
auto titles from the first question, inline rename, delete with an
Undo toast, diacritic-folding search over titles and message text.
Scope and model are remembered per conversation; history is readable
offline.
- Assistant actions: Turn into flashcards (New deck with the answer as
notes, landing on the options step - deck seed gained step) and Save
to notes (appends to the single scoped deck, trimmed at 40k).
- Chats travel in the backup export (preview counts them) and in the
encrypted sync payload; still never the key.
- Motion from lib/motion.ts: message fade-up, sheet springs for the
model/context/history sheets, 150ms composer height transition, all
skipped under reduced motion.
- Tests: chat suite 63 -> 89 checks (history, reload, rename/search/
delete/undo, actions, export, two-device sync round-trip, offline,
desktop panel). Full set: 12/12 suites, 513 checks. SW -> freezmo-v33.
Also: tests/model-compare.mjs benchmark (diagnostic) for deciding the
default text model on numbers; defaults unchanged.
Entry points (no sixth tab): Ask in the Library header (desktop button,
phone icon), Ask about this deck in the deck menu, Ask a question on
study/homework results (compact result travels as context), and a Chat
row in the desktop sidebar. Phones get a full-screen route with back +
New chat; the tab bar steps aside.
- Client-side retrieval: chunk scoped decks (~800 tokens), BM25 against
the question + recent turns, top chunks under ~7k tokens, each
labelled with deck + section. Notes come from the deck's stored
sourceText (already kept for Regenerate); decks without it fall back
to generated content and the UI says so.
- Stateless server: /api/chat validates against the CHAT_MODELS
allowlist, trims the history to ~6k tokens, caps context at ~9k and
streams token/thinking/done/error NDJSON. /api/chat/extract reduces
attachments to text through the existing vision step.
- UI: user bubbles + full-width assistant text, streaming with stop,
auto-scroll that pauses with a jump-to-bottom button, safe markdown
(React nodes, no HTML injection; KaTeX dynamically imported only when
a message has math), Thinking row for reasoning, copy/regenerate/
edit-and-resend, model + context pickers (last model remembered),
composer with visualViewport keyboard handling, safe-area, 16px
textarea, Enter-to-send on desktop.
- Usage-limit failures keep the draft and show the shared message with
Settings/Ollama actions; stopping maps the reader abort to a clean
stopped state; offline disables sending with a reason.
- Settings: Keep notes text for chat toggle; deck menu: Delete notes
text. RATE_LIMIT_CHAT + CHAT_MODELS in .env.example and README.
- Tests: chat suite (63 checks, stub Ollama) wired into run-all.
Full set: 12/12 suites, 487 checks. SW -> freezmo-v32.
Also: tests/model-compare.mjs (diagnostic) benchmarks two models on the
same notes (latency, repair rounds, activity types) so the gpt-oss vs
gemma default can be decided on numbers; defaults unchanged.
