Reported: tapping Review due could sit for many seconds with no loading
screen. The flow itself is local and fast (counts are hydrated on the
library; <1.5s even at 6x CPU throttle with 3,000 answers), so the
visible fault was missing feedback: /review is a dynamic route and
until its payload arrived nothing on screen changed.
- LinkLoadingScreen: the review card links render a full-screen
loading screen from the link's own useLinkStatus pending state, the
instant the tap happens (measured 58 ms with the route request held
open). The links also prefetch their payload.
- Route loading boundaries (loading.tsx) for /review, /stats and
/exam, sharing a RouteLoading screen (app icon + spinner +
localized message); ReviewClient's bare skeleton replaced with it.
- Health probes: per-key 30s cache + in-flight sharing in use-health.ts
(every page mounts its own gate; a session now fires one probe
instead of one per navigation). Manual re-check still forces.
- Czech fix: exam heading 'Zkouškové režim' -> 'Zkouškový režim'.
Verified by the rebuilt suites (the /tmp harness was wiped overnight):
review-loading 15/15 (stalled-request loading screen at 58 ms, session
arrival after release, fast normal path, mistakes path, end-to-end
grading, probe cache) and navigation 78/78 (tab bar, labels 360/390
EN/CS, routing, deep links, wizard loading lock). Lint + build clean.

Reported: during a loading screen (freezing a deck) the Study deck /
Make my homework switch stayed live, so the run could be swapped out
mid-flight; a request that finished afterwards could even save a deck
the user never saw and navigate them into it.
- New lib/wizard-busy.ts: a tiny store both wizards publish to while
phase === 'loading' (UploadScreen) or view.kind === 'loading'
(HomeworkScreen); WizardModeSwitch hides itself while busy.
- Both wizards abort the in-flight request on unmount, so leaving via
the header logo or the Back gesture stops the run instead of letting
it finish invisibly and save/navigate later.
- Deck Cancel keeps its long-standing behaviour (wizard + cancelled
notice + Retry), matching the freeze-loading suite.
Verified: wizard suite 92 checks (mode switch hidden during deck and
homework runs, it returns after Cancel, and a delayed reply after
leaving mid-run saves nothing and navigates nowhere) plus mobile
134/134 (also de-flaked the sheet's Escape close by waiting for
detach), regression 74/74, declutter 116/116, animation 8/8, native

freeze-loading 6/6. Lint + build clean. SW freezmo-v29.
Drawer removed (phones only; desktop rail untouched)
- MobileSidebar, sidebarOpen/useSidebarOpen, MenuIcon and the drawer's
back-gesture layer are gone; the shared nav content now serves only
the desktop rail (dead mobile branches deleted). No drawer-specific
CSS existed; the three drawer strings (header.openMenu,
sidebar.closeMenu, common.menu) and library.importAria are removed.
- The header drops the hamburger: logo + name on the left, the single
theme chip on the right.
Five-tab bottom bar
- Library / Progress / New deck (prominent centre +) / Exam / Settings,
in that order; Progress and Exam reuse the existing /stats and /exam
screens, Settings keeps opening the dialog. Sliding pill, icon bounce,
press feedback, re-tap-to-top and safe-area padding kept; every item
is >=44px (72px wide at 360px).
- New short tab.* keys (EN + CS) so all five labels stay on one line at
360px — 'Zkouškový režim' became 'Zkouška'. No ellipsis anywhere.
- The bar is mounted once in AppHeader so library, progress, exam and
share get it; the wizards keep their own bottom action bar and the
tab bar steps aside there, exactly as before.
Re-homed drawer destinations
- Smart Review card loses the Exam link (it is a tab now); Review due
and Mistakes stay.
- New deck screen (and /homework) get a Study deck / Make my homework
segmented switch; the library's homework empty-state button stays.
- The phone import icon becomes a ... button opening a sheet with
Import JSON and New folder (back-gesture and Escape close it); folder
chips still appear only once at least one folder exists, and folder
creation stays in the New deck options step.
Verified: mobile suite 134 checks (no hamburger/drawer, tab order and
44px targets, label matrix at 360/390 x EN/CS x dark/light x reduced
motion, per-tab routing, deep links, Back from every tab, the ... sheet

Check my work (third homework mode)
- One model call with its own system prompt marks the student's own
attempt: verdict, what's right, each issue with why + fix, and the
corrected version that keeps everything the student got right.
Unasked-for extras are never errors. The attempt is typed/pasted
(photos of handwriting are documented as unsupported) and stored in
the record so Redo re-checks the same work.
- Server: mode "check" + solution on POST /api/homework (zod, 400
server.needSolution without one) and the same NDJSON stream; new
checkHomework() pipeline with repair-once validation.
Follow-ups
- New POST /api/homework/refine (plain JSON, RATE_LIMIT_REFINE, zod,
auth before body): shorter / more detail / explain, plain text back,
language preserved.
- Shorter + More detail + Original rewrite the finished answer and the
corrected version in place (FollowUpBar); every guide step has
Explain step N differently; failed calls say so without losing text.
Turn into a study deck
- Any result hands its content (answer, corrected version or assembled
guide) to New deck through a one-shot sessionStorage seed with the
options step pre-filled.
UI
- Phone step 2 gains the third card: tapping it reveals the solution
field + submit; desktop has three cards and the solution field shows
with the mode. Homework history labels and share/card previews cover
the new mode.
Verified: new phase-3 suite 20/20 against a stub Ollama (check payload,
missing-solution 400, refine validation, phone + desktop check flows,
shorter follow-up with restore, guide explain, deck hand-off) plus
regression 74/74, mobile 52/52, declutter 116/116, wizard 80/80,
animation 8/8, native 35/35, phase1 38/38, phase2 43/43, i18n 25/25.
Key parity 734/734. Lint + build clean. SW freezmo-v27.
Answer history and schedules
- Every answer is recorded (deck, activity, topic, correct/wrong, time)
in a versioned IndexedDB log (freezmo-learning v1, stores answers +
srs), mirrored in memory for synchronous React reads and capped at
20k answers (oldest pruned). StudyFeed records as it grades.
- Light SM-2 schedule per activity: 1 day, 3 days, then interval x
ease; wrong answers return in ten minutes with the ease nudged down.
Review, mistakes, stats
- Library 'Smart review' card: due count, mistakes count (latest
answer wrong — clears itself when answered correctly), today's goal
progress. Review sessions freeze their item list at start.
- New /review (due across decks, ?mistakes=1 global or ?deck= per
deck) built on a shared SessionFeed with the study feed's snap/keyboard
mechanics, wake lock and a results slide.
- New /stats: day streak, five-week calendar, accuracy per subject and
per deck, weakest topics (>=3 answers), daily-goal progress.
- Daily goal configurable in Settings (10/20/30/50).
Exam mode
- New /exam: pick decks, question count, optional timer; no hints
(a NoHints context hides hint rows and the self-check escape);
results with score, per-deck and per-topic breakdown; wrong answers
land in the mistakes set through the normal history.
Reminders (conditional)
- VAPID-gated: GET/POST/DELETE /api/push and POST /api/push/test with
the standard route pattern, RATE_LIMIT_PUSH, zod, auth before body.
Subscriptions stored server-side as endpoint + keys only (PUSH_DIR).
UI hidden entirely without keys; iOS install note; service worker
push/notificationclick handlers; scripts/send-reminders.mjs for a
cron/systemd timer; web-push added as the one server dependency.
Verified: new phase-2 suite 42/42 (history/SRS shapes from a real study
run, mistakes clearing, review session, stats math, exam timer and
breakdowns, VAPID-less hidden state plus the configured
subscribe/validate/test/delete path against a second instance) plus
regression 74/74, mobile 52/52, wizard 80/80, declutter 116/116,

709/709. Lint + build clean. SW freezmo-v26.
Safety net and errors, mobile-first, desktop unchanged in behaviour.
Backup and persistence
- Settings -> Data & backup: 'Export all data' writes one zod-validated
JSON (decks, folders, homework, progress, safe settings; the API key
is not part of the shape and never appears in the file).
- 'Import backup' validates, shows a preview with added/replaced
counts and offers merge or replace; invalid files get a friendly
error. Storage persistence (navigator.storage.persist) is shown and
requestable, with the result reported.
- A dismissible nudge appears after 5 new decks or 14 days without a
backup and stays snoozed for 14 days.
Opt-in encrypted sync (off by default)
- New lib/sync.ts: PBKDF2-SHA256 (310k) -> AES-GCM-256, derived key
kept as a non-extractable CryptoKey in IndexedDB (lib/sync-key.ts);
the passphrase and key never leave the browser.
- New POST/GET/DELETE /api/sync following the route pattern (locale,
cross-origin guard, body cap, rate limit RATE_LIMIT_SYNC, auth
before body parsing, zod validation). One atomic JSON file per
random 128-bit sync ID under SYNC_DIR; server-stamped updatedAt is
the conflict clock; SYNC_MAX_BYTES and SYNC_TOTAL_BYTES enforced
(413 / 507). The server only ever sees an opaque envelope.
- Settings -> Sync: enable with a passphrase, copy the sync ID, sync
now, last-synced time, explicit keep-this-device / use-synced-copy
conflict choice, join from another device (ID + passphrase, wrong
passphrase rejected), unlock after the key is gone, delete the
synced copy (works even on a locked device). Every data store marks
sync dirty on write; pulled payloads are applied without marking
dirty again.
Monthly usage vs short-term throttling
- lib/ollama.ts classifies the real 429 body (monthly/quota/upgrade
vs burst) into new 'usage_limit' and 'throttled' kinds, mapped in
every route and in the health probe.
- The client renders the same localized message in the deck flow,
homework, grading and the Settings banner: the required
upgrade/new-key copy with 'Open Settings' (jumps to and focuses the
key field) and 'Open Ollama'. Input and wizard drafts are kept so
Retry works right after swapping the key. No model fallback.
Verified: new phase-1 suite 38/38 (backup content + no key, import
preview/merge/replace, junk file, persistence row, nudge + snooze,
sync enable/upload/opaque blob/push/join/wrong passphrase/delete,
server validation 400/401, usage-limit copy and key focus, and the
real route mapping against a stub Ollama for both 429 variants) plus
regression 74/74, mobile 52/52, wizard 80/80, declutter 116/116,
animation 8/8, native 35/35, i18n 25/25. Key parity 638/638. Lint +

The wizard-polish restructure put the phone branch before the loading
check, so 'Freeze my deck' left the wizard on screen (looking like
nothing happened) until the router landed on the finished deck. The
loading state is now checked before the phone flow, for both layouts.
New freeze-loading suite (6 checks): the staged loading screen appears
immediately after Freeze, shows the stage message and Cancel, unmounts
the wizard bar, and Cancel returns to the wizard with the cancelled
notice instead of getting stuck.
Regression 74/74, mobile 52/52, wizard 80/80, declutter 116/116,

System integration
- Manifest: id, display_override, monochrome icon, Make my homework
shortcut and a share target (text/URL via GET, files via POST).
iOS startup images for the common iPhone sizes. Pinch-zoom is allowed
again (double-tap zoom is disabled via touch-action instead).
- Share target: /share chooser with New deck / Make my homework; POSTed
files wait in a 10-minute in-memory store, reach the wizard through
sessionStorage and never touch disk.
- Web Share: Share rows for decks (JSON file where supported) and the
homework result, with a clipboard fallback and a toast.
- Offline: a quiet pill appears and Freeze / mode cards are disabled
with a clear reason; input is never lost (error cards keep Retry).
- State: wizard drafts (text, options, photos up to a size budget)
survive reloads and OS kills and are cleared on success; re-tapping
the active tab scrolls to the top; the deck page shows a skeleton
instead of a spinner.
Navigation and gestures
- System Back closes the topmost layer first: a small history-entry
stack (lib/use-back-close.ts) covers the drawer, Settings sheet,
install sheet, deck actions panel and one wizard step; navigations
are never rewound and stale entries are skipped.
- Destructive-but-reversible actions use Undo toasts: deleting a deck
(no confirm) and removing a file in the wizard. Irreversible ones
keep their confirm.
Input and feedback
- Every phone input got inputmode / enterkeyhint / autocomplete /
autocapitalize / spellcheck; Enter on the last field advances the
wizard; a clipboard-paste button appears where the API exists.
- Haptics behind a Settings toggle (on by default): tab switches,
toggles, correct/wrong, completion; Vibration API + the iOS hidden
switch tick, throttled and silent everywhere else.
- Wake lock during the study feed and homework guide, released on
leave and re-acquired when the tab returns.
Verified: new native suite 35/35 (manifest/head/viewport, offline,

Needs a real device (documented in the README): iOS haptic tick,

Mobile only (<=639px); desktop markup untouched.
Bug fix: the Back/Next bar was fixed-positioned inside the screen
entrance animation's transformed wrapper, so it painted under the content
and jumped to the viewport bottom about a second in. It is now portalled
to <body> and only fades in, pinned to the bottom from the first frame.
The other fixed/sticky elements (tab bar, drawer, sheets, install sheet)
were checked and live outside the animated wrappers.
- The step name is now the large headline with a one-line description;
the repeated page title is dropped on phones. Thin progress bar + 1/3.
- Step 1: formats/limits hint, one big dashed Add photos or files area
(plus icon), Camera and Paste text instead as secondaries, and a
'nothing added yet' placeholder that becomes the thumbnail/chip list.
- Next is disabled until a photo, file or pasted text exists; step 3 can
never be reached empty.
- Step 1 shows Cancel (back to the Library) instead of a dead Back.
- Step 3 is a real summary: thumbnail/chip strip plus Files, Difficulty,
Activities and Folder rows, each with an Edit link to its step; Freeze
is the single primary action.
- Step 2 got a visible Difficulty label and a helper line under every
group, defaults still preselected.
- Bottom chrome: flat full-width Back/Next bar above the safe area, and
the tab bar hides inside both wizards. The lower-right orb is hidden on
phones so it can never glow behind the bar.
- Make my homework matches: headline, hint, big add area, placeholder,
Cancel, gated Next, flat bar.
Verified: new wizard suite 80/80 (bar position sampled at 5 frames during
the entrance from tab bar/drawer/empty state; 360 + 390, dark + light,

Mobile only (<=639px / coarse pointers); desktop keeps its behaviour.
Foundation
- lib/motion.ts owns the spring presets (snappy/gentle/sheet), durations,
easings and variants (screens, tabs, wizard steps, list stagger).
- Native-feel CSS: press feedback scales every button, card, chip, tab,
row and summary to 0.96 with a spring-like cubic-bezier on transform
(scoped to phones/coarse pointers), tap-highlight off, touch-action
manipulation, chrome text non-selectable, reduced motion drops it.
- App shell fades in once on launch; the study feed fades in on phones.
Applied
- Tab bar: sliding active pill (shared layoutId) + icon bounce.
- Study Decks/Homework, language toggle, difficulty and size pickers:
the same gliding highlight, gated so desktop keeps the old styling.
- Route content enters direction-aware (deeper = from the right, back =
from the left, same-depth = crossfade) via RouteTransition on the
library/create/homework content columns; library tab switches
crossfade; wizard steps slide forward/backward (reduced motion safe).
- Library: cards fade up in a capped stagger on first load, glide with
layout animations and shrink away on delete (AnimatePresence).
- Study feed: correct feedback pulses, wrong shakes, the progress bar
settles with a spring curve, score and XP count up on the results.
- Settings sheet uses the sheet spring; the drawer now follows the
finger and closes on release velocity, like the sheet.
- Generation progress: the stage message fades/slides between stages;
the icon keeps its gentle wobble; the feed fades in on hand-off.
Skipped, on purpose: LazyMotion (the sliding highlights need layout
animations = domMax, same features the current import already has);
route exit animations (the App Router unmounts the outgoing page —
exits are handled by in-page AnimatePresence); replacing the study
feed's native scroll-snap with finger-follow drag (would fight the
platform scroller); finger-follow height animation for native <details>
expanders.
Verified: animation suite 8/8 (reduced motion + 4x-CPU-throttled trace:

Phones only (<=639px); desktop markup is untouched.
- New deck is a 3-step flow: progress (1/3 + bar) and a fixed Back/Next
bar above the tab bar. Step 1 = Add photos or files / Camera / Paste
text instead (no drop zone or paste copy on touch), step 2 = folder,
difficulty and count with defaults plus one collapsed focus/notes row,
step 3 = one summary line (photos/docs/text · difficulty · count ·
folder) with Freeze. Going Back keeps every input; step transitions
respect prefers-reduced-motion.
- Make my homework is a 2-step flow sharing the same pattern; tapping a
mode card starts it (no separate CTA on phones), with a short preview
of the assignment on step 2. The hero is now 'Make my homework' /
'Udělej mi úkol' everywhere ('Solve your homework' is gone) and the
intro is one line.
- Library: stats line removed, folder row and 'Unorganized' heading
hidden until folders exist (New folder lives in the drawer), Import is
a small icon button beside the tabs. Deck and homework cards are
compact on phones: title, one meta line (activities · difficulty ·
best), a one-line description that expands on tap, the whole card
tappable and a small Study/Open pill instead of the full-width button.
- Settings sheet on phones: no .env.local subtitle; Language stays first;
one Connection card (status dot + 'Connected · 2 models ready', key
field with the eye inside, Save only when edited, auto re-check on
save, refresh icon instead of Test connection); privacy one-liner with
a More expander (daemon tip inside); raw health rows behind one
collapsed Details list; Remove key as a small danger button at the very
bottom (same confirmation).
- Decorative orbs on phones moved further off the screen edges so they
never glow under cards or primary buttons.
- Shared markup for folder/difficulty/count and mode cards keeps one
source of state; new lib/use-phone.ts gates the layouts.
Verified: new declutter suite 116/116 (360 + 390, EN + CS, photo + PDF +
pasted text, Back keeps input, summaries, settings flow), regression

Retrying the missed items could leave the feed on a stale position: the
retry swaps the queue (8 slides -> 3) and resets the scroll on the OLD
element, while the browser was still finishing a smooth scroll or snap.
Depending on the engine that could strand the viewport past the new
content (blank feed with the header still showing the old counter), and
the results slide kept its inner scroll because it has no key.
- The scroller now carries key={runId}, so every run mounts a brand-new
element: scroll position 0, fresh snap state, no inherited inner
scrolls in any slide.
- The scroll listener re-attaches to the new element (deps [runId]).
New retry suite 12/12: plain retry (fresh element, slide 1, header
Retry 1/N, missed item answerable again), retry fired mid smooth-scroll,
double-tap retry, and retry -> answer -> results -> retry again — all
land on slide 0 with content visible. Regression 74/74, mobile 51/51,

A short-answer case: "Why was Kryštof Harant executed?" with the student
answering "because he took part in the anti-Habsburg uprising" was failed
for not naming the year 1621 — a detail only present in the reference
answer, never asked by the question. The generator had put the date into
keyPoints, and the grader treated every key point as mandatory.
- Grading prompt: the QUESTION defines what is required. A key point
counts only when the question asks for it or the answer is wrong or
incomplete without it; extra detail in the reference answer (dates,
places, names, numbers) is a bonus — never listed as missing, never a
reason to fail. An accepted answer must return an empty "missing"
array.
- Generation spec: short_answer keyPoints must contain only the ideas
the question asks for (a "why" question requires the reason, not the
year).
- gradeShortAnswer drops any stray "missing" entries when correct is
true, so the UI can never show a gap on an accepted answer.
Verified: mock-Ollama integration test 9/9 through the real /api/grade
route (new rules sent upstream, incorrect answers keep their missing
point, accepted answers normalise to missing: []), regression 74/74,

The staged loading screen still rendered the pre-redesign logo — a white
snowflake in a blue rounded square — while every other surface (header,
sidebar, empty states, key gate, install sheet) uses the app icon.
- LoadingState now shows /icons/icon-512.png at size-28 with the same
gentle wobble animation; 512px keeps the 112px render crisp on hi-DPI
phones.

The last visible difference between the two CTAs was the container: the
deck button lived in a full-bleed sticky strip (translucent background,
hairline top border, its own padding), which also tinted the disabled chip
differently. The homework button sits plainly in the page flow.
- The CTA block is now a plain space-y-2 stack at the end of the form:
full-width button + centred helper line, exactly like /homework.
- /create's page padding switches from the sticky-era .pb-cta (9rem, phone
override 4.6rem) to .pb-tabbar, and lg:pb-20 to lg:pb-16 — identical to
the homework page. The now-unused .pb-cta rules are gone.
- Result: same button width (358px @390 / 688px @1280), height, radius,
helper placement and trailing space on both pages; neither has a sticky
ancestor any more.

Correcting the previous change: instead of stripping the snowflake from
"Freeze my deck", "Make my homework" now carries the homework flow's own
sparkles icon, and the snowflake is back on the deck button.
Both CTAs are now identical in shape — feature icon + label, full-width,

The two CTAs already shared the same Button size="lg" shape (full-width,

the last visible difference was the snowflake icon on "Freeze my deck".
Dropped it so the button is text-only exactly like "Make my homework" —
the snowflake stays on the hero, the drop zone and the tab bar.

- "Freeze my deck" is now a full-width (w-full) button in its sticky bar,
like "Make my homework", instead of a compact left-aligned button in a
flex row.
- The status/validation line ("Add a photo or a document (or some text) to
start.") moved from above the button to centred directly underneath it,
with the same 12px muted styling the homework flow uses.
- Both flows now share the Button size="lg" shape (44px tall, 14px radius,
same muted disabled chip, centred text); hover/disabled behaviour comes
from the same .btn-primary/.btn-disabled classes.

Header & action bar
- Import JSON no longer disappears on the Homework tab: it sits directly
under the "Your icebox" header/subtitle, above the tab switcher, on every
tab — so switching pools no longer shifts the layout or hides actions. It
is one secondary button at all sizes now, not a quiet link when empty.
- The decks-only "Homework Solver" header action is gone; the homework tab's
empty-state CTA and the drawer cover starting a new solve.
Empty states
- Dropped the "Using your own Ollama models — check the connection in
Settings." line (and its two dictionary keys) everywhere.
- Both tabs share one structure: ice icon -> heading -> short description ->
primary CTA button, starting at the same height:
Study Decks: "No decks yet" -> "Freeze a page of notes into flashcards
and quizzes." -> "Create study deck"
Homework: "No homework yet" -> "Solved assignments and step-by-step
guides show up here." -> "Solve homework"
- CTA labels read as actions on the standardized nouns; removed the now
unused actionStudyDeck/actionHomework keys.
Tabs
- Link segments are 44px tall at every breakpoint (min-height in the base

Verified: library-consistency suite 49/49 (Import visible with a fixed
position on both tabs, no Ollama text, empty states at the same y, primary
ice CTA buttons >=44px, deep links, deletion, redirects, desktop, 360px, axe
en+cs light+dark), mobile 51/51, i18n 27/27, desktop regression 74/74.
Lint + build clean.
Library ("Your icebox")
- Two tabs, never mixed: Study Decks (the folder + card library) and Homework
(saved solutions and step-by-step guides). The active tab lives in the URL
(/?tab=homework), so the sections are linkable and survive a reload.
- Decks tab keeps Import, the folder bar, stats and its own empty state — now
a single decks-only CTA.
- Homework tab lists saved results as cards (mode icon, date, step count,
preview) with Open and delete-with-confirm; its empty state has its own CTA
("Homework Solver") that opens the solver directly. Opening a card
deep-links to /homework?open=<id>, which the screen opens on arrival.
- .segmented now also styles link segments (same control as settings).
/create
- The redundant "Study Deck | Homework Solver" toggle is gone: /create is the
deck uploader only, and the bottom bar's + goes straight to it. Homework has
its own screen, reached from the library tab, the drawer and CTAs.
Copy
- New keys (en + cs): tabDecks, tabHomework, homeworkHeroTitle, plus homework
empty-state/open/step-count strings. The homework hero is now "Solve your
homework" / "Vyřeš svůj úkol" — no study-deck text in the homework flow.
- Removed the now-unused ModeSwitch component and homework.title key.
Service worker: freezmo-v10.
Verified: library-tabs suite 37/37 (tab switching, context empty states,
deep-link opening, deletion, no switch on /create, heroes, redirects, desktop
grid, 360px + 44px targets, axe contrast en+cs light+dark), mobile 49/49,
i18n 27/27, desktop regression 74/74. Lint + build clean.
Terminology (lib/i18n-dict.ts)
- One name per mode everywhere: "Study Deck" / "Studijní balíček" and
"Homework Solver" / "Řešitel úkolů". The library empty-state cards and the
/create switcher now read the same, so the choice no longer changes name
between screens.
Deep links
- Library quick actions carry the mode: /create?mode=deck and
/homework?mode=homework.
- Both pages canonicalize: /create?mode=homework redirects to the homework
flow and /homework?mode=deck redirects to /create, so a mode link always
opens that mode directly.
/create
- The two bulky square cards (106px tall, wrapping/clipping "Study Deck &
Qu…" on phones) are replaced by a compact segmented control (52px) placed
directly above "1. Add your notes": ice pill, snowflake/sparkles icons,
44px segments and one-line labels at 360px. The pill slides to the chosen
segment and the route follows ~190ms later, so toggling reads as one smooth
transition (immediate under prefers-reduced-motion).
Service worker: freezmo-v9.
Verified: mode-switch suite 26/26 (deep links, cross-mode redirects, 52px
control, 44px segments, no clipping/wrapping at 360px, "1. Add your notes" at
y=394 of 740 with the upload controls above the fold, pill slide, axe contrast,
en+cs, phone+desktop), mobile 49/49, i18n 27/27, desktop regression 73/73.
Lint + build clean.
Library empty state ("Your icebox")
- Replace the single "Make your first deck" button with two quick-action
cards: "Create interactive test" (primary, ice-gradient icon + subtle
accent border) and "Help me with my homework" (glass card, sparkles
icon). Stacked on phones, side by side from 640px up; both >=44px tall.
/create
- Replace the "Got homework instead of notes?" banner with a two-card mode
switcher above "1. Add your notes": "Study Deck & Quizzes" (the current
view — aria-current, accent tint, ice icon) and "Homework Solver" (a
shortcut to /homework). Icon-on-top tiles on phones, inline rows from
640px up; glass tokens + backdrop blur in both themes.
Strings
- New keys in both dictionaries: emptyStateCreateDeck, emptyStateHomework,
actionStudyDeck, actionHomework. Drop the now-unused homework.entry and
library.makeFirst keys.
Drive-by AA fix (light mode, /create only)
- The "New folder" dashed button and the difficulty blurbs move from
frost-500 to frost-600 (4.0:1 -> ~6:1). Dark mode is unchanged.
Service worker: freezmo-v8.
Verified: redesign suite 32/32 (stacked/side-by-side layouts, 360/390/1280,
dark+light, en+cs, >=44px targets, both cards navigate, no overflow, axe
contrast), mobile 49/49, i18n 27/27, desktop regression 73/73. Lint + build
clean.
On phones the "Freeze my deck" strip floats one tab-bar height (4.6rem)
above the viewport bottom, but the page reserved env + 9rem of trailing
room — so at the end of the scroll the strip docked ~70px higher than where
it had been floating, leaving a visible cavity above the tab bar.
Phones now get exactly the sticky offset (env + 4.6rem) as trailing space:
the strip settles where it was floating and the bar is never double-counted.
Tablet/desktop (>=640px) keep the roomier 9rem — unchanged.
Verified at 360/390px: gap CTA-to-bar 70.3px -> 0.3px, ~70px less dead
scroll; tablet 800px and desktop 1280px measurements identical to before.
Service worker: freezmo-v7.
Homework (/homework — entry points in the drawer and on the create screen)
- Assignment intake reuses the study pipeline: pasted text, photos
(camera/picker, compressed in the browser) and documents (PDF/DOCX/PPTX/
ODT/text) through lib/image + lib/documents, the same vision step and the
same language guard. Raw files never leave the device — only text and JPEG
data URLs reach the server.
- Two large choice cards: “Just make it” returns the finished homework
(answer only, plain text, copy + make it again); “Explain how to make this
homework” builds an interactive guide.
- The guide is one step per screen in the study-feed snap layout:
explanation, three progressive hints (nudge -> hint -> the answer) and an
optional checkpoint rendered by the existing activity components (graded
through /api/grade). The last screen assembles the solution from the step
answers, with a copy button. Checkpoints carry xp 0 so the guide stays free
of XP/streak chrome.
- Results live in freezmo.homework.v1 with a small history (open/delete);
“Make it again” re-runs from the stored assignment text (the vision
transcription when photos were used) — no original files are stored.
- The answer and the guide are written in the assignment's language, never
translated into the UI language.
Server
- POST /api/homework: NDJSON stage events like /api/generate, the same
http-guard, auth checked before parsing, and its own RATE_LIMIT_HOMEWORK
(documented in .env.example + the README table).
- New prompts in lib/prompts.ts and zod schemas in lib/schemas.ts with the
same single repair retry; TEXT_MODEL for content, VISION_MODEL only for
photos. New shared client pieces: useNotesIntake, lib/homework store,
lib/clipboard, and a shared NDJSON reader in lib/client-api.
Also finishing the mobile polish pass from the previous request
- Phone ice scene: the top-left orb moved behind the glass header (it sat
behind the page heading/subtitle). The settings sheet's scroll cue is now a
bare chevron inside a content fade (mask) instead of a chip over the status
banner, and the API key card's note/disclosure/actions are tightened.
- theme-color now follows the in-app theme (SSR metas still fall back to the
OS preference); apple-mobile-web-app-status-bar-style stays “default”
because iOS fixes the status-bar text colour at launch.
Verified: 78/78 homework checks (text/photo/PDF, both modes, EN+CS, dark+light,
360/390px, copy, history persistence, storage privacy, API language, axe), plus
the existing suites re-run (mobile 47/47, pixel contrast 0 below AA, i18n 27/27,
desktop regression 72/72). Lint + build clean; service worker freezmo-v6.
Phones (<=639px) only for layout/gestures; the theme-level fixes apply
everywhere, as they are token/design changes.
Settings sheet
- Swipe-to-dismiss reusing the InstallSheet gesture: the sheet follows the
finger, closes past ~90px or on a fast flick, snaps back otherwise. Drag
starts only from the handle/header and only while the body is scrolled to
the top. Backdrop tap still closes.
- Fixed header + scrollable body: pb-safe + spacer, so nothing is clipped;
a scroll cue (chevron) fades in while more content is below and out at
the end.
- Show/Save stack under the field at 44px on phones; close, Test connection
and Remove key are 44px too. Remove key is now a rose destructive action
with a confirmation that the full-screen key setup comes back.
- API key note split into a short privacy line plus a collapsible
'Using the local daemon?' tip (OLLAMA_AUTH=local / .env.local / signin).
- Fixed the missing space in the English tip ('ollama signin instead.').
- Health: kept the auto-check and banner; added a loading row and a
'Checked just now' / 'Checked at HH:MM' freshness label (also for errors).
Ice scene / readability
- Verified the orbs were never above content (fixed z-index:-1 layer,
pointer-events:none); they were just shining through the glass. Phones get
lower blob/orb opacity and orbs tucked to the edges; the bottom-right orb
is moved out from under the tab bar and the tab bar paints a more opaque
surface so its labels hold contrast.
Contrast / themes
- Dark --text-subtle raised to #9db1d0 (8.6:1 page, 7.2:1 glass); helper
text now uses the tokens.
- Disabled buttons are a visible muted chip (.btn-disabled) instead of a
40%-opacity ghost.
- One ice primary gradient in both themes; danger/success now actually show
their colour (bg-none strips the primary background-image that used to
paint over !bg-rose-600).
- Light mode: cool card rims instead of white-on-white, stronger shadow.
Redundancy / touch
- Removed only the header gear; the hamburger drawer (folders, Settings,
theme) and the tab-bar Settings stay.
- Theme toggle is a bordered chip with an action aria-label (drawer row too).
- Empty library hides the folder pills, demotes Import to a quiet link and
keeps a single primary CTA. 44px targets for nav rows, segmented control
and folder pills on phones.
- Fixed a pre-existing 16px horizontal overflow (header -mx-4 vs a
padding-less parent) and let info values wrap instead of truncating.
Verified: mobile suite 47/47 (EN+CS, 360/390px), pixel-sampled contrast
audit 0 runs below WCAG AA (8 runs, both themes/locales; axe marks the glass
'incomplete'), i18n 27/27, desktop regression 72/72, lint + build clean.
Service worker cache bumped to freezmo-v5.
English stays the default; Czech is a full translation. Only the app chrome
is translated - notes and generated decks keep their own language, which is a
core feature, not a setting.
i18n
- lib/i18n-dict.ts: flat en/cs dictionaries (441 keys each), translate() and
translatePlural() with real Czech plural rules (1 sada / 2-4 sady / 5+ sad).
English is the default and the fallback for a missing key.
- lib/i18n.ts: browser store (freezmo.locale.v1), useI18n() hook, and the
x-freezmo-locale header. The hook's t/plural are bound to the locale React
is rendering with, so the first client render matches the server HTML and
then re-renders in the stored language; module-level t is only for event
handlers and non-React helpers.
- <html lang> follows the choice (inline script + setLocale).
UI
- Settings -> Language segmented control (English / Cestina), plus an EN/CS
button on the key gate for first run.
- Every screen translated: sidebar, header, tab bar, library, deck cards,
folder bar, create flow, all seven activities, study chrome, results,
settings + health panel, API-key gate and help, install sheet, offline and
the deck-not-found page.
- Plural-aware counts everywhere (decks, folders, activities, runs, photos,
documents, pages, words, wrong attempts).
Server
- API routes and guards (generate, grade, health, http-guard, rate-limit,
ollama error mapping) answer in the request's language, so error cards and
the health panel never fall back to English mid-sentence.
Fixes
- A hydration mismatch when a non-default locale was stored silently dropped
the .dark class after hydration; render-time t() is now bound to the
hook's locale (UploadScreen.describeExtraction, ResultsScreen.answerFor,
DeckCard's folder fallback).
- Bumped the service worker cache to freezmo-v4 for this deploy.
Tests: i18n 27/27 (gate toggle, persistence, html lang, Czech plurals,
settings switch) and a rebuilt regression suite 72/72 (English default,
library, create, all 7 activity types, results, settings, install sheet,
offline, PWA, security, Czech smoke).
Source artwork committed as assets/app-icon-source.jpeg (1024x1024 navy
rounded square) and scripts/make-icons.mjs rewritten to render every icon
from it with headless Chromium:
- The master is masked at full resolution first (a rounded rect 4px inside
the artwork's own radius), so the JPEG's anti-aliased white edge never
survives and small sizes downscale with clean alpha.
- PWA icons (192/512) and favicon-32 keep the rounded square with
transparent corners; apple-touch 180/167/152 are full-bleed (iOS paints
transparency black) with the artwork zoomed 20% to crop its corners;
maskable-512 keeps the artwork inside the 80% safe circle on a matching
navy field.
- iOS splash screens regenerated with the new mark.
- app/favicon.ico regenerated (PNG payload in an ICO container); the old
app/icon.svg removed so the browser tab can't fall back to it.
- Install sheet's app card now shows the real icon, so the home-screen
icon is recognisable.
- Service worker CACHE_VERSION bumped to freezmo-v3 so installed clients
pick up the new assets.
- README updated (source artwork + script description).
Verified: pwa 16/16, install sheet 64/64, final ux 12/12, key gate 49/49,
zoom 6/6; every icon route serves 200 and the manifest/head reference the
new files.
Next.js 15 app that turns photos, PDFs, DOCX/PPTX and text into a swipeable
feed of AI-generated activities (flashcards, multiple choice, true/false,
fill-in-the-blank, matching, ordering, short answer) using the user's own
Ollama models.
Highlights:
- All AI calls run in server route handlers; the browser never talks to Ollama.
- Bring-your-own-key mode (default): the key lives only in the browser and is
sent per-request; server, local-daemon and shared-key modes also supported.
- Client-side document extraction (pdf.js, mammoth, jszip) with scanned-PDF
page rendering for the vision model; notes stay in their original language.
- ChatGPT-style shell: collapsible sidebar / mobile drawer, neutral token-based
light + dark themes, folder organisation, PWA (manifest, SW, offline page).
- Strict JSON validation with zod + auto-repair, rate limiting, and request
guards (cross-origin, body-size, API-key sanitising).
- setup.sh bootstraps deps, .env.local and a production build.
Gitignore excludes .env*, the generated pdf.js worker and local scratch files.
