HANKAN_TUTOR_BACKEND=openai talks to anything serving
/chat/completions -- LM Studio, Ollama, llama.cpp, vLLM, LiteLLM,
OpenRouter, OpenAI. The TutorBackend seam already existed for this, so the
model becomes a config line rather than a code change.
Written against fetch rather than the openai package. The Anthropic SDK
alone is 14MB in the image, this backend uses one endpoint with no tools
and no retries, and local servers are the ones most likely to deviate from
an SDK's expectations. The real risk in hand-rolling it is SSE reassembly,
so that is where the tests are: a JSON payload split across two TCP reads,
an event whose blank-line terminator lands in the next read, heartbeat
comments, CRLF framing, and a stream that ends without [DONE]. The two
split cases both fail against a naive per-read parser, which is what makes
them worth having.
<think> blocks are stripped from the stream, tags split across chunks
included. Reasoning models served locally often emit chain-of-thought
inline in `content` rather than in a separate field, and left in it lands
in the lesson transcript where the block parser reads it as prose.
WHAT THIS COSTS: prompt caching. The Anthropic backend marks the ~12k
character gate as a cached prefix, so every turn after the first reads it
at a fraction of the input price. There is no portable equivalent, so
against a paid hosted endpoint the system prompt is re-billed every turn --
the biggest cost lever in the design, gone.
Against a local model it costs nothing, and the shape still pays: llama.cpp
and LM Studio reuse their KV cache for an unchanged prefix. Measured on a
6,948-character prompt against gpt-oss-20b, first token 1,563ms cold and
324ms warm, so the system prompt goes first and stays put here too.
Verified against LM Studio running openai/gpt-oss-20b, not only a fake: a
turn streams from the browser through this server to the model and back,
rendered in the chat, no page errors.
Also makes test/server/http.test.ts backend-agnostic. It asserted the echo
backend's wording and so failed the moment the server was pointed at a real
model -- precisely the case a transport test should survive.

The Android build always talks to the Pi cross-origin -- a Capacitor
webview serves the app from http://localhost, not from your domain -- so
the browser sends a preflight OPTIONS first. It is not permitted to attach
an Authorization header to that. Auth ran before anything else, so the
preflight came back 401 and the real request was never attempted.
There were no Access-Control-Allow-* headers either, so even a successful
preflight would not have helped. Verified from an actual page before the
fix: GET /api/sync and POST /api/tutor both "Failed to fetch" -- an opaque
network error that points at the network rather than at middleware order.
CORS now runs first and answers OPTIONS itself. Any origin is allowed by
default, which is not a hole: the gate is a bearer token rather than a
cookie, so a hostile page gains nothing from being allowed to send a
request it cannot authenticate. HANKAN_ALLOWED_ORIGINS narrows it.
backends/echo.ts is a keyless backend that reflects the request back in
chunks. Deploying involves a container, a reverse proxy, a token, CORS and
an SSE stream that has to survive compression -- five things that break
independently, none of which involve Anthropic. HANKAN_TUTOR_BACKEND=echo
proves all five from the phone before a key exists and before anything is
billed. CI now runs the server that way, so the tutor endpoint is
exercised over real HTTP rather than only against an injected mock.
test/server/http.test.ts covers the preflight, the allow-origin header on
real responses, Vary: Origin, that a bad token is still refused, and that
the SSE stream parses and terminates with a done event.
Verified end to end in a browser: the Pi configured through the settings
panel, sync pushing 2 rows and a second sync moving 0 (the pushedAt
watermark holding), the header switching from "local stand-in" to
"connected", and a turn streaming back over SSE with the 8,859-character
system prompt intact.

The previous pass measured with a 50ms timer and reported zero. A
MutationObserver plus the Layout Shift API disagreed: three log-height
shrinks per turn and two places where the reply's text went backwards.
Timer sampling had simply missed the frames.
Raw markup was flashing. A directive line arrives before the block it
opens is complete, and until then parse() has no reason to treat it as
anything but prose -- so "::task match" and "::words" rendered as visible
text for one frame and then vanished when the next line closed the block.
The streaming preview now drops :: lines outright, since blocks are not
rendered until the turn commits. It also trims the blank line that
preceded the directive, which MessageBody renders as a 9px gap: that gap
opened and closed on every block boundary.
The answered exercise no longer collapses. It was replaced by a one-line
"exercise answered" the instant Send was pressed -- around 170px out of
the log in a single frame, the largest jump in the view, and it threw away
what the learner had typed. It now stays rendered read-only, dimmed, with
the answers still legible.
Autoscroll never worked on a phone. Below 900px tutor.css sets the log's
max-height to none, so it has no internal scroll and setting scrollTop did
nothing -- a new reply just landed below the fold. It now scrolls whichever
element is actually the scroller. In the page-flow case the target is the
composer, not the bottom of the document: the word rail renders below the
chat, so following the document would scroll past the whole rail on every
turn. A reader who has scrolled up is still left alone.
Measured per turn, desktop: text regressions 2 -> 0, log-height shrinks
3 -> 0, DOM mutations 9 -> 5, CLS 0.0026 (only the word rail's own footer,
which is real content changing). Mobile: the composer stays in view and
the newest message is on screen; scrolled-up reader unmoved at y=200.

TaskHost.tsx used a literal NUL as the delimiter in its drag-and-drop
payload, and tools/dict/build.mjs used one to join headword and part of
speech. Both work at runtime. Both also make the file *binary* to every
text tool: git shows "Bin 12259 bytes" instead of a diff, and grep prints
nothing at all for a match.
That is not hypothetical. Searching TaskHost.tsx for "<input" came back
empty three times while reviewing it, which is how its four exercise
inputs came to be reported as absent -- and why the accessibility defect
in them went unseen. Written as the escape \u0000 the value is identical
and the file stays text.
test/source-hygiene.test.ts fails on any control byte in a source file, so
this cannot come back quietly.
With the files readable again, the sweep the NUL had been hiding: eleven
form controls had no accessible name. The exercise blanks announced only
an ellipsis, and the part-of-speech select announced nothing. A
placeholder is not a label -- it disappears the moment you type. All
eleven now carry one, named after the thing they answer.
`npm run lint` gains --max-warnings 0. exhaustive-deps is configured as a
warning, so a hooks-dependency bug would have passed CI silently.

Three separate causes, all measurable with a MutationObserver over a turn.
The reply vanished and came back. On completion the code cleared
`streaming` and only then wrote the turn, trimmed the transcript and read
it back -- three awaits during which the message was unmounted, the typing
dots took its place, and the log jumped by the message's height. The write
now happens first and the placeholder is swapped for the committed turn in
one render.
The dots blinked again underneath the finished reply, because `busy`
stayed set until the finally block: one render with the turn committed and
the pending slot still mounted with `streaming` back to null. All three
state changes are now in the same batch.
The log shook while streaming. scrollIntoView() scrolls every scrollable
ancestor, so each token nudged the page as well as the log, and it fired
unconditionally, so scrolling up to re-read something was undone by the
next token. It now writes scrollTop on the log alone, once per animation
frame, and only when the reader is already within 80px of the bottom.
Also: the pending bubble is one keyed node rather than two sibling
conditionals, so waiting-to-streaming no longer remounts; and the
transcript is parsed once per change instead of on every render -- every
keystroke in the composer was re-parsing up to 26 messages of blocks.
Measured before: 1 bubble-count drop, 2 log-height shrinks, page scrolled
per token. After: 0, 0, and the page never moves.

The text-entry rule was an allowlist of type= values, which fails twice.
An <input> with no type attribute is a text field but matches no
[type=...] selector at all, and any type nobody listed falls through
silently. Both had happened: the add-a-word fields carry no type, and the
server URL and token are url and password. All four rendered as white UA
boxes on a dark page.
A denylist of the controls that must keep native rendering — checkbox,
radio, range, colour, file, the button-like ones — cannot rot the same way.
color-scheme now sits on :root per theme rather than nowhere. It is what
tells the browser to paint the parts CSS cannot reach: the select dropdown
list, spinner arrows, scrollbars, the autofill wash.
Separately, .tiles draws its hairlines with its own background, so as a
stretched grid item it filled the rest of the hero's height with a solid
block of line colour. align-self: start.

The seed pre-marked the artifact's 30 headwords secure on first run. Two
reasons it is gone rather than merely disabled:
It was never 30 cards. The match was on headword, and homographs each
carry their own lemma, so 그 as pronoun and as determiner both matched —
47 rows for a 30-word list.
Worse, "Reset everything" deleted the cards and then deleted the
'seed.known' guard along with the other meta keys, so the next boot
re-seeded and the deck looked untouched. The one thing a wipe exists for,
undone by the wipe itself.
Migration 5 clears the seed from installs that already have it. seedCard()
is the only writer that leaves updated_at = 0 on a card and the seed was
its only caller, so `DELETE FROM card WHERE updated_at = 0` removes exactly
the seeded rows and nothing the learner graded — the timestamp rule paying
for itself a second time.
test/domain/reset.test.ts pins both scopes: what a full wipe must leave
empty, what a roadmap reset must keep, that the deletions are tombstoned
so a sync cannot restore them, and that migration 5 really runs against a
schema-4 database rather than the test performing the delete itself.

CI starts postgres:16-alpine and the sync server before npm test, so the
round-trip runs for real instead of skipping. A fake would not exercise
the change_seq trigger, the last-write-wins upsert or cursor paging, which
is exactly where sync goes wrong.
Also corrects the stale advisory count in the validate.mjs comment: the
updated export bundle carries data/gloss-extra.json, and the baseline has
been 0 blocking, 0 advisory since it landed.

compose.yaml joins the Pi's existing network as external and reaches the
Postgres and Caddy already there by name; nothing is published to the
host. The schema applies itself on boot, so there is no migration step to
run by hand.
The Caddy snippet in the README is the part worth reading. Excluding
/api/tutor from `encode` matters more than flush_interval: compression
delays the header flush until body bytes arrive and holds already-flushed
events inside an unfinished frame, which presents as a stream that hangs
rather than as an error.
Untested against the actual Pi — written from PORT.md and verified only
as far as building the image and running it against a local Postgres.

POST /api/tutor takes the assembled system prompt, the transcript the
client owns, and the new message, and streams tokens back. It holds
nothing between requests, so a dropped connection costs one turn rather
than the conversation.
The seam moved first: Sample took the assembled prompt as messages[0] with
role user. It now has an explicit system field, which is what lets the
backend put it in the API's system parameter as a cached block. The gate
is ~12k characters and is byte-identical for as long as the learner stays
in one unit, so every turn after the first reads the prefix at a fraction
of the input price. That is the single biggest cost lever in the design,
and it was unreachable through the old shape.
prompt/tutor-system.md still ships unchanged; only where the string is
placed changed.
SSE has three rules that are silent when broken, and all three are
handled: every event ends with a blank line, payloads are JSON-encoded
because a raw newline in Korean text would break the framing, and a `:`
heartbeat every 15s keeps intermediaries from timing the stream out.
Cache-Control is set on the returned Response rather than inside
streamSSE, which writes its own and would overwrite it; `no-transform` is
there because compression, not buffering, is what usually makes SSE look
like it hangs behind a proxy.
The client uses fetch + getReader, not EventSource — EventSource cannot
POST, and the body is {system, history, message}. Aborting closes the
connection, the server aborts upstream, and a cancelled turn stops
billing. With no server configured the app falls back to the stub, so the
offline build is untouched.
backends/anthropic.ts is the default. backends/agent-sdk.ts is deliberately
unimplemented and documents why the plain API was chosen over PORT.md's
Agent SDK — chiefly that its prompt accepts only user-role messages, so
the transcript would have to be flattened into a single turn.
The endpoint's own tests use a mock backend and need no API key.

Hono and pg, run under --experimental-strip-types, so the deployed thing
is the source. GET /api/sync?cursor=N pages rows above the cursor;
POST /api/sync upserts last-write-wins. Bearer token on everything under
/api; /health is open, for the container healthcheck.
Rows are stored generically — primary key as text, body as JSONB —
because the server never reads inside a row. It stores and orders them and
the client interprets them, which keeps the two schemas from having to
move in lockstep.
change_seq is bumped by a BEFORE UPDATE trigger rather than by the write
path. A row edited after a client last pulled would otherwise keep its old
sequence, sit below that client's cursor, and never be delivered; putting
it in the database means no future write path can forget.
The last-write-wins comparison is in the ON CONFLICT clause itself, so a
losing row is not written at all and does not bump change_seq — a
conflict does not become traffic for every other device.
test/sync/roundtrip.test.ts runs two clients against a real Postgres and
asserts what actually goes wrong in sync: that a fresh client's seeded rows
cannot overwrite the server's history (the artifact's bug, as an executable
test), that a delete propagates, and that dict.loadedBands never crosses
the wire. It skips without HANKAN_TEST_SERVER, so npm test still runs
anywhere.
POST /api/test/reset exists only when HANKAN_TEST_MODE=1, so it cannot be
reached on the Pi even if the token leaks.

Row-level last-write-wins on updated_at, cursor-based on a server-assigned
change_seq. The schema was built for this in step 1, so the work here is
the three things it did not yet have.
Tombstones (migration 4). Row-level sync cannot express a delete: with the
row gone there is nothing to compare timestamps against, so the other
device pushes its still-live copy back and the row silently returns. Every
delete path now writes a tombstone inside the same transaction.
The wire format lives in shared/sync-protocol.mjs and is imported by both
sides, so there is one definition rather than two that drift. It carries
the syncable-meta allowlist, which is the load-bearing part: meta mixes the
learner's preferences with bookkeeping that describes one install, and
replicating dict.loadedBands would tell a phone that had loaded bands 0-2
it holds every row the desktop has — the word rail would then fail to find
words it believes are present.
The sync loop pushes first, then pages the pull. Two details it would be
easy to get wrong, both commented at their site:
- The pull cursor advances only as rows are applied, never from the push
response. The server's newest change_seq includes rows this device has
not seen; adopting it skips them permanently, and nothing ever asks for
that range again.
- Pulled rows advance sync.pushedAt too, bounded by the instant the sync
started. Otherwise they look like local edits and get pushed straight
back, and an edit made during the sync is not swept up with them.
Seeded rows carry updated_at = 0, so a fresh device is never dirty and can
never win a conflict — the artifact's clobbering bug stays unrepresentable.

Six gaps the last review named, closed.
FOCUS SELECTOR. FOCUS_MODES and focusLine() already existed and already fed
{{FOCUS}}; nothing in the UI ever set prefs.focus, so it was permanently
"auto". Now a seven-mode picker in the chat header, with a compile-time
check that every listed mode exists in FOCUS_MODES — a typo would otherwise
render an empty {{FOCUS}} silently.
ADD YOUR OWN WORD. Custom words live in `lemma` beside the dictionary, with
ids from a reserved range starting at 10,000,000. The build assigns ids
sequentially from 1, so a custom word placed in that range would be
overwritten the next time the band files reloaded.
`lemma` is UNIQUE on (headword, pos) and the shipped dictionary is large, so
"add a word" collides with an existing entry regularly — 각성 already being
there is the normal case, not the exceptional one. Adding an existing word
now gives it a card and says so, rather than throwing an unhandled UNIQUE
violation into the console, which is what the first cut did. Its curated
gloss is kept; overwriting one from a text field would be a poor trade.
Only custom rows can be deleted outright.
GRAMMAR NOTES. Per-point textarea, saved on blur. Shares one JSON-in-meta
helper with the learned flags and the trainer score.
SEEDED KNOWN WORDS. The artifact's 30-word SEED_KNOWN list, applied once
after the bands load — they have to exist as lemmas to be matched. Applied
through seedCard(), so updated_at stays 0: it matches the artifact's own
stampInit() behaviour, and it keeps the seed invisible to sync when that
lands. 47 cards, because several headwords appear as both a curated word
and a sentence chunk, and he knows both.
FULL RESET. Two scopes, each spelled out before the second press. Neither
touches the dictionary — it is reference data, rebuildable from the assets,
and wiping it would leave the app unable to gloss anything.
ABOUT PANEL. lexicon.stats() was written and unused. It now reports what is
loaded here against what shipped, the storage driver, and the attribution —
which is a licence obligation, not decoration.
Verified in a browser: focus persists across reload, notes persist, a
colliding word is adopted, a new word round-trips through add and delete,
and 47 cards seed secure on first run.

The PWA manifest declared icon-192.png, icon-512.png and favicon.svg. None
of the three existed, so install-to-home-screen and the browser tab both
resolved to nothing. That was a defect in what the last pass claimed as
done.
Drawn procedurally with Pillow rather than authored as SVG: there is no
dependable SVG rasteriser here to convert from, and ImageMagick falls back
to its MSVG renderer, which cannot be trusted with text. Pillow's
FreeType + RAQM stack shapes Hangul correctly, which is the only hard
requirement. The mark uses the app's own register — the serif face already
used for 한칸 on the boot screen, in --jade on --bg.
Two glyphs read well at 180px and up; at favicon sizes 한칸 turns to mush,
so the small sizes carry 한 alone.
icon-192 · icon-512 · apple-touch-icon (180) 한칸
icon-512-maskable 한칸 at 56%, inside
Android's circular crop
favicon.ico (16/32/48) · favicon-32 한
Sizing is a binary search on the drawn ink extent, and centring uses the ink
bounds rather than the font's line box — CJK metrics leave asymmetric space
above and below, which would otherwise sit the mark visibly high.
Re-running the generator writes byte-identical files.
Android launcher icons are untouched; Android work is out of scope.

npx cap add android, plus the SQLite and Keyboard plugins and
android:windowSoftInputMode="adjustResize" so the on-screen 한글 keyboard is
not covered by the system one.
npx cap sync copies dist/ — including the dictionary band files — into the
APK's assets, so the phone build is as offline as the web one.
Build output is gitignored; the project itself is committed. No APK has been
built: this machine has no Android SDK, so sqlite.native.ts has never

React + Vite + TypeScript, PWA, offline-first. Six tabs: 수업 오늘 단어 문장
문법 한글, plus the full-screen SRS review overlay, the reading drill, the
conjugation trainer and the 두벌식 keyboard.
The visual language is carried over deliberately: two hand-tuned palettes,
three type stacks, about a dozen component classes, zero border-radius and
no icons anywhere — Korean glyphs do the work icons would.
THE GATE is the reason this app exists. buildGate() already took a
vocabQuery hook; filling it with a band query is what turns 371 hand-typed
words into something that scales. Three refinements sit inside that hook,
all of them narrowing:
1. words a not-yet-finished unit is the first to introduce are excluded,
so a frequency ceiling cannot smuggle 3.4's material into 2.1;
2. Phase 1 is filtered by the phonological ladder;
3. the list is capped at 800 by frequency, because renderGate() inlines
it into the prompt — strictly more restrictive than the band, so it
cannot leak.
prompt/tutor-system.md ships unchanged with {{GATE}} filled by renderGate().
Confidence is clamped per turn. The artifact wrote the model's ::progress
number straight into the sole gate on advancement, so one hallucinated 95
skipped a unit.
stub-tutor.ts stands in for the model on the artifact's exact contract —
onText receives cumulative text, an aborted turn keeps what it streamed —
so the real endpoint drops in without touching the UI. It rotates all four
task types and climbs progress gradually, which makes every render path
reachable with no server.
Two artifact bugs are not ported: task state lived in the full-page
re-render, so anything arriving mid-answer wiped typed text and placed
chips; and the day number was computed once at module load, so a session
left open overnight scheduled against yesterday.
Verified in a browser: all six tabs work, and after a hard reload with the
network cut every tab still works — including dictionary search out of OPFS.

Closes REVIEW.md §2. 167 of 371 roadmap words had no lexicon entry, so the
word rail silently showed nothing. Now:
Roadmap words: 371/371 resolve
Spiral targets: 35/35 resolve
Deck words: 386/386 resolve
and npm run dict:assert makes it a blocking build failure, not a silent
empty rail.
No runtime morphological analyser ships. lib/conjugation.js surfaceForms()
runs at BUILD time over every verb and adjective, so looking up a conjugated
form is an index hit on the surface table.
The frequency join had to be inverted. A subtitle frequency list holds
surface forms; a dictionary holds lemmas whose -다 citation form barely
occurs in running text, so joining on headword gives verbs a frequency of
roughly zero. Expanding each lemma into the forms it plausibly takes and
summing recovers 하다 from 118 to 89,041. Forms claimed by more than one
lemma are dropped rather than split, so homographs don't inherit each
other's mass. Those expansions score frequency only — the surface table
itself stays strictly surfaceForms() output plus the headword.
Bands are one per curriculum phase. Phase 1 admits no frequency band at
all: during the writing-system phase every word must be phonologically
legal for the unit reached, and a rank ceiling would hand the learner a
겹받침 during unit 1.4. shared/phonology.mjs lifts validate.mjs's own
feature ladder to enforce that; it agrees with the validator on all 371
words.
Sources are chosen automatically — KRDICT when vendored, otherwise the
kaikki.org extract. KRDICT's download is a JS form behind anti-bot
protection, so it cannot be fetched by CI; the derived band files are
committed instead, which the app needs offline regardless. Attribution and
the share-alike terms are in NOTICE.md.

Nothing above db/ knows which driver it got. sqlite.web.ts runs
@sqlite.org/sqlite-wasm in a dedicated Worker; sqlite.native.ts uses the
Capacitor plugin. Both apply the same migration array.
The web driver uses the OPFS SAHPool VFS rather than the plain opfs VFS:
the latter needs COOP/COEP cross-origin isolation headers, which neither a
static host nor the Capacitor webview reliably provides. Same storage,
fewer deployment constraints.
THE TIMESTAMP RULE. The artifact had a sync bug where a fresh device
stamped its own empty defaults as newer than the server's real history and
clobbered it. Three layers make that unrepresentable rather than merely
avoided:
1. updated_at INTEGER NOT NULL DEFAULT 0 on every syncable table, so
forgetting the column is the SAFE failure — a row that loses every
last-write-wins comparison, not one that wins them all.
2. writes.ts splits every mutation into seedX() (never stamps) and
editX() (always stamps), and is the only file allowed to read the clock.
3. An ESLint rule enforces that, and the conformance suite asserts a
freshly seeded database has no non-zero updated_at anywhere.
Two batching limits are sized for the platform we cannot test here: Android
links the system SQLite, historically capped at 999 bound parameters, while
sqlite-wasm allows 32766. A multi-row insert sized for the browser would
fail only on the phone, at first launch, loading the dictionary. Both the
band insert and the word-rail lookup batch under the smaller ceiling, and
test/db/limits.test.ts fails at 3600 if that regresses.

lib/ ships unchanged, so its types live in types/lib/ and are wired up by a
tsconfig path mapping. Adding types costs nothing; reimplementing the logic
would cost the two things that make this port possible.
The tests exist so a later refactor cannot silently drift them:
hangul the nine Composer cases named in the export README —
먹어 · 왔어 · 읽어 · 괜찮아 · 값 · 의사 · 뭐야 and backspace
conjugation all seven irregular classes, and every form in
IRREGULAR_FORMS reachable through haeche()
srs the SM-2 transitions, ease and interval clamps
blocks parse → answerText round-trip for all four task types
101 tests.
One is a pinned defect rather than a guarantee. blocks.parse() never closes
a ::gloss block on its "=" line, so a multi-sentence gloss — which the tutor
prompt explicitly invites — collapses into one run-on line keeping only the
last translation. lib/ ships unchanged, so the test records the real
behaviour and the app works around it at the call site.

The export bundle is the input to this port, not a sketch: the curriculum,
the tutor prompt and the five logic modules are finished and tested. They
land here byte-identical and stay that way.
diff -r export/data data && diff -r export/lib lib
diff -r export/prompt prompt && diff export/validate.mjs validate.mjs
data/, lib/, prompt/ and validate.mjs sit at the repo root so validate.mjs
runs verbatim with no path edits. All four are excluded from lint and
formatting — they are not ours to restyle. Types for lib/ live alongside in
types/ rather than as sibling .d.ts files, so the verbatim check stays a
plain directory diff.
CI runs the curriculum gate first, before anything else can pass:
node validate.mjs PASS — 0 blocking, 0 advisory
