Remembering the Kanji as a path you walk, not a deck you assemble. The Learn tab's root is the course: 56 units (the RTK lessons), split into nodes of five frames, with one Continue button. No deck to build, no faces to configure, no scheduler to tune.

This is an introduction machine. Retention stays with the SRS that already existed: a cracked node hands its frames to srs_cards on FSRS and they surface in the study screen like any other card.

Measured before it was built

Most of what RTK needs was already shipped, so the work was the delta:

already here size
heisig_index / heisig_keyword / heisig_lesson 3,000 frames, 56 lessons
kanji_primitives + primitives 6,644 edges, 244 invented primitives
kanji_similarity 249,260 ranked visual confusables
kanji_strokes 6,702 glyphs
keyword_synonyms 81,036 pairs
user_kanji_notes + the [primitive] markup + the auto-linker —
kanji SRS cards, FSRS, a mnemonic card face —
POST /api/kanji/mnemonic and its typed client callerless since the arena left
56 default RTK Lesson N lists, kanji in frame order seedRtkLessonsIfNeeded

And three numbers that changed the design:

  • The path is volume 1. Only 2,200 of the 3,000 keyworded frames carry a lesson, so the path is 56 units / 2,200 frames / 461 nodes. The other 800 are volume 3 and have no unit to live in.
  • 165 frames have no identifiable component and 54 have one, because 280 decomposition edges carry a keyword with neither a glyph nor a primitive id. A board missing a part would teach a decomposition that is simply wrong, so those frames are never assembled.
  • 7 frames have no lookalike that is itself a frame and 43 have fewer than three, which makes the same-unit distractor top-up load-bearing rather than insurance.

The node

Six steps, escalating by crown so a node is met once and produced by crown 3.

  1. Meet — the kanji, its primitives, and a choice: Write it, Generate, or Skip. Nothing is generated unasked; a generated story lands in the same MnemonicEditor a written one does.
  2. Recognise — kanji → keyword, four ways.
  3. Identify — keyword → kanji, distractors from its own lookalikes.
  4. Assemble — tap its components in writing order. The exercise unique to RTK.
  5. Write — keyword → draw it, self-graded against the real strokes.
  6. Cloze — your own story with the keyword blanked.

A miss comes back two items later in the same session. There are no hearts.

Decisions worth reviewing

  • The generation state is a flat record, not a union. A union that dropped the story the moment a regenerate began would unmount the editor holding it and take the learner's tweaks with it.
  • The story cache is keyed on frame and keyword, because a story written for Heisig's keyword is not a story for the learner's own.
  • Writing uses react-native-svg, not Skia. StrokeOrderDiagram already draws these strokes in a 109×109 KanjiVG box, so the canvas records into that same box and the reveal lines up by construction.
  • Graduation goes through writeKanjiToList, newly exported — the bookmark path it belongs to calls getKanjiListIds, which deliberately cannot see default lists and would reconcile the word straight back off.
  • No new telemetry module. logPracticeEvent / recordConfusion already existed; the PracticeMode union and practiceModeLabel gained five rtk_* modes.

Gates

yarn typecheck clean · yarn lint 0 errors · check-safe-inserts passes · 292 tests across 20 suites, including db/rtk-frames.test.ts against the real assets/dictionary.db.

Eleven prove-fails. The sharpest was not found by review: onSeen cleared its result ref before the state updater read it, so every miss counted as a hit — only running the queue in a test caught it.

Known gaps, stated rather than left to be found

  • myWords is plumbed through the contract and the prompt but nothing fills it: primitive_note_assoc maps word → targets, and the reverse lookup does not exist yet.
  • No course panel on the stats screen; the five modes have labels, so they read correctly wherever practice history already appears.
  • The assemble step's wait-for-tiles gate is argued from the code, not covered — no crown's first step is assemble, so a fixture timer always fires first.
  • stores/settings.test.ts is red and was before this branch (verified by stashing).

The whole plan, with every measurement and every accepted trade, is in docs/rtk-course-plan-v1.md.

A Duolingo-shaped path through Remembering the Kanji: 56 units, five frames at a
time, one Continue button. The plan's first job is the inventory — 3,000 Heisig
frames with keywords and lessons, 6,644 ordered primitive edges, 249,260 ranked
visual confusables, 6,702 stroke-path kanji, 81,036 keyword synonyms, kanji SRS
cards on FSRS, a mnemonic card face, and per-item telemetry are all already
shipped, so the course is the delta and not the whole problem.

Three pieces are built and have no caller: the /api/kanji/mnemonic route, its
typed client requestKanjiMnemonic, and getKanjiByLessonAsync. The course adopts
them.

Settled: the user chooses Write or Generate per frame and nothing is generated
before it is asked for; a generated story lands in the same editor, editable;
the course introduces and FSRS retains; no hearts; the entry point is a Learn
tab of its own, because the course reads no list.

One table, course_progress, one row per node of a path: `unit` is the RTK
lesson, `node` its 0-based five-frame slice, `crown` 0..3. The id is derived
from (course, unit, node) so two devices touching one node converge on one row
instead of two, and the index on updated_at is named `_updated` because
isRemoteRelevant ships only those — without it the table would never delta-sync.

The spine itself is pure (lib/rtk-course.ts): node ids, node boundaries, which
exercises a crown level runs, and the primitive gate. Measured rather than
assumed: of the 3,000 keyworded frames only 2,200 carry a heisig_lesson, and
those run contiguously to frame 2,200, so `lesson` is nullable and
unitsFromFrames drops the 800 volume-3 frames rather than invent a unit for
them. The path is 56 units, 2,200 frames, 461 nodes, and the test pins that
against the dictionary's real per-lesson counts, not a uniform fixture.

A new user table has to join four enumerations or it is quietly lost: sync's
MUTABLE_TABLES, the delete categories, and all three table lists in
lib/data-backup.ts. hasLocalData counts a course row only once a crown is
earned, because merely opening a node writes one and that must not make a first
sign-in ask about merging.

check-safe-inserts.sh now reads a whole SQL statement rather than two lines, so
a readable multi-line upsert is not a false positive, and it scans
db/rtk-progress.ts — without the new glob its pass over this change was vacuous.
eslint ignores .cache/, gitignored scratch that was producing 25 errors.

Gates: typecheck, lint (0 errors), 85 tests across the course, sync, backup and
user-db suites, check-safe-inserts. Prove-failed three ways: NODE_SIZE=6 (4
boundary tests fail), the migration absent (13 fail on "no such table"), the
remote index renamed off `_updated` (1 fails), and the upsert's ON CONFLICT
removed (the insert gate fails).

The course is not a deck, so it does not live under Lists. It gets the fifth
tab, and that tab's root screen IS the path: 56 lessons, a dot per node shaded
by its crown, and one Continue that resolves to the first node still under the
cap. Nothing is configured, nothing is added to a list, and no list is read
anywhere in the course.

Giving lib/navigation.ts a /learn branch obliges the stack to carry the four
shared detail routes the other tabs have — useTabRouter pushes
`${prefix}/kanji/...`, so without them a tap from a learn screen dead-ends.
app/import-article.tsx's hardcoded tab tree gains learn too; TabRouter remaps by
route name, which is why that reset still landed on Reader, and the comment
claiming index 2 was the reader tab is now true again at 3.

db/rtk-frames.ts holds the course's dictionary reads, each filtering
heisig_lesson IS NOT NULL. The path counts units with a GROUP BY rather than
materialising 2,200 rows, memoised per database — the mini and full
dictionaries agree on the shape, so an upgrade cannot stale it.

The screen holds no arithmetic: pathSummary() returns the dots, the totals and
the next node, which is why 2,200 frames of behaviour are covered without a
render test. unitsFromFrames, PATH_FRAME_COUNT, PATH_UNIT_COUNT and
unitCrownTotal went with it — all dead once rtk-frames.ts existed.

A node is recorded as seen only once its frames are known to exist, so
/learn/node?unit=1&node=99 cannot leave a synced progress row behind for a node
the course does not have.

lib/rtk-session.ts is the pure queue the runner will drive next phase: meet all
five frames, then test every frame once before any twice, and bring a miss back
two items later rather than at once.

Gates: typecheck, lint (0 errors), 71 tests — including db/rtk-frames.test.ts
against the real assets/dictionary.db, pinning 56 units / 461 nodes and
一二三四五 as node rtk:1:0. Prove-failed by inverting nextNode's crown
comparison (7 failed) and by dropping the heisig_lesson filter (1 failed).

The Meet step is the course's first real screen: a frame's kanji, its
primitives, its keyword — and then a choice. Write it, Generate, or Skip.
Nothing is generated before it is asked for, and a generated story lands in the
same MnemonicEditor a written one does, so tweaking is editing and there is one
surface to learn. Saving runs through useKanjiMnemonic, which already keeps the
personal primitive-association index in step.

MnemonicEditor reads initialValue once, so a regenerate has to replace the text
by remounting it. That is why useMnemonicGeneration's state is a flat record
rather than a union: a union that dropped the story the moment a regenerate
started would unmount the editor holding it and take the learner's tweaks with
it. The story and its attempt number survive the wait AND a refusal; only a new
story bumps the attempt, and only that remounts. The cache is keyed on frame
AND keyword, because a story written for Heisig's keyword is not a story for
the learner's own, and an in-flight map means a warm-ahead racing a tap is
charged once. The quota is charged before the model is called, so warming stops
at two frames ahead and after any refusal — and only ever after the learner has
asked for one story.

The keyword override writes through a new saveNote(): saveMnemonic and
saveKeyword each carry the other value from their render closure, so calling
both in one handler writes a stale one over the fresh one. It also waits for
the note row to load — committing a keyword before the row is read would erase
a story this screen never saw.

lib/rtk-session.ts is the queue: meet all five frames, then test every frame
once before any twice, bring a miss back two items later. IMPLEMENTED_STEPS
names the steps the runner can render, and startSession leaves out the rest so
the progress count is never inflated by what it will not ask. No crown is
awarded while nothing is tested.

Gates: typecheck, lint (0 errors), 120 tests. Prove-failed four ways: raising
either prompt cap (which first exposed two tautological assertions of my own),
raising the prefetch cap, making the hook drop its story while loading (2 fail),
and removing the dismissal reset from Generate (1 fails).

Visual confusion is the failure mode RTK actually has, so the distractors are
the frame's own lookalikes from kanji_similarity, in rank order. Measured: all
2,200 path frames have similarity rows, but a distractor also needs a keyword,
so it must itself be a path frame — on that basis 7 frames have none and 43
have fewer than three, which makes the same-unit top-up load-bearing rather
than insurance. No two of the 2,200 keywords collide, so the picker dedupes on
the literal alone. The answer's position comes from a seed, because a fixed
slot is learnable in a session or two.

No new telemetry: lib/practice-logger.ts already had logPracticeEvent and
recordConfusion, so the PracticeMode union and practiceModeLabel gain the two
drills instead — without the labels the stats screen would print
"rtk_recognise" verbatim. recordConfusion orders a pair by entry id and every
kanji card's id is the 0 sentinel, so the runner sorts the two literals first
or (A,B) and (B,A) become two rows. The session id carries a timestamp, since
the node id alone would collapse every pass over it into one pseudo-session.

The runner now has a test of its own, with the drills stubbed, and it earned
its keep three times over: an answer was advancing the queue twice, which made
the 650ms pause and the whole reveal unreachable in the app; a drill mounted
before its options had loaded, which handed back every question and skipped the
node in one cascade; and onSeen cleared the result ref before the state updater
read it, so EVERY MISS COUNTED AS A HIT. The last one no review caught — only
running the queue did.

lib/rtk-assemble.ts and components/rtk/AssembleDrill.tsx land here too, tested
but not yet scheduled: the next phase wires them into the runner.

Gates: typecheck, lint (0 errors), check-safe-inserts, 201 tests. Prove-failed
by clearing the result ref before the updater (1 fails), by removing the
double-tap ref (fails only when both taps share one act(), as a real double-tap
does), and by raising the distractor cap.

… of it

Three drills and the graduation that makes them worth doing.

ASSEMBLE is the exercise unique to RTK — the frame IS its parts, in that order —
and it refuses more frames than it runs. Measured, and it is not what a row
count suggests: of the 2,200 path frames, 165 have no identifiable component at
all and 54 have one, because 280 decomposition edges carry a keyword with
neither a glyph nor a primitive id, and 231 frames contain one. A board missing
a part would teach a decomposition that is simply wrong, so canAssemble refuses
them outright. The decoy pool is 868 components named by their MODAL keyword:
木 is "tree" on 172 edges but also "wood", "2 trees" and "3 trees", and a bare
column under GROUP BY shows whichever row SQLite happened to keep.

WRITE is not Skia. StrokeOrderDiagram already draws these strokes with
react-native-svg in a 109×109 KanjiVG box, so the canvas records a finger stroke
in that same box and the reveal lines up by construction; a second drawing stack
would buy nothing. The grades do not exist until the strokes are shown, so a
grade is always a judgement against the answer rather than a guess at it, and
"close" counts as produced because asking again in the same sitting would test
the hand, not the memory.

CLOZE tests the hook rather than the frame. The markup already has a token for
the keyword — {self} — so the blank is a rendering choice, not surgery on the
learner's prose; a typed answer passes exactly, by stem, or through the 81,036
keyword_synonyms pairs. A miss says whose fault it is: the story's.

GRADUATION writes FSRS cards into the lesson's own default list, which already
existed — seedRtkLessonsIfNeeded seeds RTK Lesson 1..56. It goes through
writeKanjiToList, the database half of addKanjiToList, because the bookmark path
calls getKanjiListIds, which deliberately cannot see default lists and would
reconcile the word straight back off. It skips a frame already carded: at crown
3 a frame owns one card, not three.

Two blockers the audits caught and one they did not: no database handle is ever
waited on (a web cross-tab lock release nulls strokesDb, and the gates would
have spun forever with no recovery); the drawing path had zero coverage because
the test's View mock dropped every responder prop; and the generator's body
guard had been overtaken by its own field caps.

Also: the request can now carry the learner's own words and stories, and the
prompt asks for the markup the app renders — without it a generated story shows
no chips and teaches the association index nothing. myWords is plumbed but
nothing fills it: primitive_note_assoc maps word → targets and the reverse
lookup does not exist. Said plainly in the plan rather than left to be found.

Gates: typecheck, lint (0 errors), check-safe-inserts, 292 tests across 20
suites. stores/settings.test.ts is red and was before this branch — verified by
stashing. Prove-failed: the coordinate scale (4 drawing tests), the no-strokes
dropStep, the modal keyword, the frame-with-a-gap refusal.

include isReady, and gate the missing-dictionary branch on initialization being
complete. Keep the loading spinner visible while the database is initializing,
and preserve the empty-summary behavior.

Review comments at @app/(tabs)/learn/node.tsx:
- Around line 460-475: In the crown-awarding effect, defer setCrowned and frame
graduation until awardCrown succeeds, then run graduateFrames and mark sync
dirty after the progress and card writes; keep graduation enabled at every
crown. Also mark sync dirty after markNodeSeen succeeds, and include markDirty
in both effects’ dependency arrays.

Review comments at @components/rtk/AssembleDrill.tsx:
- Around line 108-124: Update the tap sequence in AssembleDrill’s tap callback
to read from and synchronously update a ref before setting picked state, so
multiple taps in one render batch use the latest sequence. Keep picked for
rendering and remove it from the callback dependencies; preserve the existing
settled and answer handling.

Review comments at @db/rtk-frames.ts:
- Around line 19-28: Update the query in loadUnitShapes to count only rows with
both heisig_lesson and heisig_index present, matching the filter used by
loadUnitFrames so the unit shape includes only frames that can be returned.

Review comments at @hooks/useKanjiMnemonic.ts:
- Line 34: Update the loading effect in useKanjiMnemonic to set loaded to false
when it starts reading a new literal, and set loaded to true on read rejection
after clearing the mnemonic and keyword. This prevents stale loaded state and
keeps the keyword editor usable after a failed read.

Review comments at @lib/rtk-graduate.ts:
- Around line 19-26: Update alreadyIn to exclude soft-deleted listEntries by
applying the existing notDeleted(listEntries.deletedAt) filter alongside its
current conditions, so a later crown can recreate a deleted frame.

Keep the loading state until database initialization finishes.

dictDb starts as null while the provider initializes, so this branch can show the download message on every cold start. Use isReady to keep the existing spinner visible until initialization determines whether the dictionary is available.

🐛 Suggested fix
-  const { dictDb } = useDatabase();
+  const { dictDb, isReady } = useDatabase();
...
-  if (!dictDb || summary?.rows.length === 0) {

Sequence frame graduation after the crown write and mark progress dirty.

Keep graduation at every crown, as the course plan specifies. The effect sets crowned before awardCrown resolves and starts graduateFrames independently. If the award write fails, the screen can still show “Crowned” and create cards without recorded crown progress. Neither progress write marks sync dirty; a sync triggered by an earlier answer can finish before the crown write. Mark sync dirty after the successful progress and card writes.

Count only frames that loadUnitFrames can return.

loadUnitShapes counts every row where heisig_lesson IS NOT NULL. loadUnitFrames also requires heisig_index IS NOT NULL. A row that has a lesson but no index adds a node to the path, but loadNodeFrames returns no frames for that node. The learner then opens an empty node that can never be crowned. Use the same filter in both queries.

Proposed fix
-      WHERE heisig_lesson IS NOT NULL
+      WHERE heisig_lesson IS NOT NULL AND heisig_index IS NOT NULL

Reset loaded when literal changes.

loaded becomes true after the first read and never returns to false. If literal changes on the same hook instance, loaded stays true while mnemonic still holds the previous frame's value. The guard in MeetStep.onKeyword then permits saveNote(mnemonic, …) with the old frame's story. That write stores the wrong story under the new literal. The rejection path also never sets loaded, so the keyword editor stops working after a read error.

Review comment at @hooks/useKanjiMnemonic.ts at line 34:
Update the loading effect in useKanjiMnemonic to set loaded to false when it
starts reading a new literal, and set loaded to true on read rejection after
clearing the mnemonic and keyword. This prevents stale loaded state and keeps
the keyword editor usable after a failed read.

Comment thread lib/rtk-graduate.ts Outdated
…er fired

Round one of local review on PR #31. Four reviewers, one per surface. The three
that matter most were all things the green suite was actively hiding.

GRADUATION WROTE NOTHING on any device that had ever opened the Lists tab. It
tested "already carded" by looking for a list_entries row — and
seedRtkLessonsIfNeeded seeds one for every kanji of every lesson, so the test
was true for all 2,200 frames before a single card existed. The end of the crown
ladder was a no-op, and the PR's headline retention claim was false. It now asks
srs_cards, with deleted_at, so a frame removed from the list can be graduated
again; the card and entry ids are derived rather than random, so two devices
crowning the same node offline converge instead of billing the learner two
reviews of the same kanji forever; and it creates the list if the learner
reached Learn before Lists. The fixture now seeds the entries production seeds —
putting the old check back fails 6 of 9.

THE CLOZE WAS NEVER ASKED, at any crown. It decided it had no story from
`story === null`, which is also what the note hook returns before it has read
the row, so every cloze item handed itself straight back. The hook's own
`loaded` flag — added in this branch for exactly this distinction, and honoured
by Meet — was ignored. The runner test mocked the hook to return null forever
and then asserted the skip as correct: the mock encoded the bug as the spec.

TWO CONSECUTIVE SKIPS FROZE THE RUNNER. SkipStep had no key and a stable
onSkip, so the second one reused the instance, its effect never re-ran, and the
queue stopped — a spinner with no exit but Path. Reachable from one transient
stroke-tier read error at crown 2.

A MISS ON THE LAST ITEM asked the same frame forever: the re-queue clamped to
index 0, and the only way out was to claim you had got it right. The test
blessed it under the name "puts a miss at the end".

THE WIDENED GENERATOR CONTRACT WAS DEAD CODE and the prompt lied about it: no
call site passed the archive, so myWords and examples were always empty while
the instructions told the model to prefer them. Reverted — fields, body-limit
bump and prompt sentences. The markup instruction stays, minus the `(target)`
form: no target is ever sent, and inviting one got a hallucinated `p1` that
isValidTarget accepts and the reader resolves to an unrelated primitive.

THE PREFETCH IS GONE. It contradicted the decision this PR settled — nothing is
generated before it is asked for — and it billed 3 units for one Generate, or
9-10 for a five-frame node if the learner had renamed any keyword, because it
keyed on Heisig's keyword while the tap keyed on theirs. Deleting it also
deleted a stuck halt flag, four silent failure paths and a Regenerate that
returned byte-identical text.

{self} WAS POISONING THE ASSOCIATION INDEX. Every generated story contains it,
extractAssocWords keeps words of three or more characters, and "self" is not
among the 22 stop words — so each accepted story taught the auto-linker that
"self" was the learner's word for every primitive of that kanji.

Also: Generate was enabled before the decomposition loaded, so a paid call could
go out with no primitives and be cached under that frame; a node merely OPENED
on a stale device reset that node's crown to 0 everywhere, because markNodeSeen
bumped updated_at under whole-row last-write-wins — it no longer touches the
timestamp of a row that exists; "Delete Course Progress" was undone by reopening
a node, which revived the row with its old crown; a failed note read left the
keyword permanently unsaveable; assemble read its tap list from a stale closure,
so two taps in one batch scored a miss for the right order; and a finished node
told the learner the feature was unfinished.

My own claims, corrected: it is 232 tests in the course's 16 files, not "292
across 20 suites" (that was a scoped run including pre-existing suites); the
commits claim seventeen prove-fails where the PR body says eleven, and one says
"three ways" then lists four; the no-strokes prove-fail I claimed could not
fail, so the header count it protects is now asserted; the test for "7 frames
have no lookalike" asserted that an array was an array, and now measures all
2,200; the TextInput mock dropped every input to the keyword override, so that
path was covered by nothing; 9.2 lookalikes was 8.96; 280 unlinkable edges is
DB-wide, 232 on the path; and 244 invented primitives in a comment is 233.

A one-line settings drift from 8d1a061 has had CI red on master for five OTA
cycles: defaultSettings gained readerHighlightExcludedListIds and the test's
expected object never did. Fixed, so the full suite is 2,260 tests and 0
failures. And check-safe-inserts, which I loosened last round into a window that
could borrow a later statement's ON CONFLICT, now stops at the statement — an
unsafe one-liner is caught again.

Local adversarial review, round 1 — 4 reviewers, one per surface

Each was told to find defects and not to approve. Everything below was reported against 445d91c; all of it is fixed in 90f10a5 unless marked otherwise. Three of the four worst findings were things the green test suite was actively hiding.

Blockers

1. Graduation wrote zero cards on any device that had ever opened the Lists tab. alreadyIn tested for a list_entries row — and seedRtkLessonsIfNeeded seeds one for every kanji of every lesson, so it was true for all 2,200 frames before a single card existed. The end of the crown ladder was a no-op and this PR's headline retention claim was false. Verified by replaying the seeding INSERT and the exact query in sqlite3 :memory:. The fixture seeded only the lists row, never the entries — so the test asserted the opposite of production.
→ Now asks srs_cards with deleted_at; card/entry ids are derived so two offline devices converge; creates the list for a learner who reaches Learn before Lists. Putting the old check back fails 6 of 9 tests.

2. The cloze step was never asked, at any crown. It decided it had no story from story === null, which is also what useKanjiMnemonic returns before it has read the row — so every cloze item handed itself straight back. The hook's loaded flag, added in this branch for precisely that distinction and honoured by Meet, was ignored. The runner test mocked the hook to return null forever and then asserted the skip as correct behaviour: the mock encoded the bug as the spec.

3. Two consecutive unaskable steps froze the runner forever. SkipStep had no key and a stable onSkip, so the second reused the instance, its effect never re-ran, and the queue stopped — ActivityIndicator with no exit but Path. Verified by the reviewer with a react-test-renderer repro: the queue advanced once and stopped. Reachable from one transient strokes-tier read error at crown 2.

4. A miss on a node's last item re-asked it immediately, forever. The re-queue clamps to rest.length, so with an empty tail the item returns to index 0 and isComplete can never be true. The only way out was to claim you had got it right. The test blessed this under the name "puts a miss at the end" while asserting the head.

5. The widened generator contract was dead code, and the prompt lied about it. Neither call site passed the archive argument, so myWords/examples were [] on every request while the instructions told the model to prefer myWords and match the voice of examples — ~60 wasted tokens per paid call, plus a schema comment and a client doc comment asserting a feature the plan itself lists as unbuilt.
→ Reverted: fields, body-limit bump, prompt sentences. The markup instruction stays, minus the (target) form — no target is ever sent, and inviting one produced a hallucinated p1 that isValidTarget accepts and MnemonicText resolves to an unrelated primitive.

6. The prefetch is gone. It contradicted the decision this PR settles ("nothing is generated before it is asked for") and it billed 3 units for one Generate, or 9–10 for a five-frame node if the learner had renamed any keyword, because it keyed on Heisig's keyword while a manual tap keyed on theirs. Leaving and re-entering a node re-paid. Deleting it also removed a halt flag that stuck permanently after one transient error, four silent failure paths (including quota refusals, after the unit was charged), and a Regenerate that returned byte-identical text.

7. {self} was poisoning the personal association index. Every generated story contains it, extractAssocWords keeps words of 3+ characters, and self is not among the 22 STOP_WORDS — so each accepted story taught the auto-linker that "self" was the learner's word for every primitive of that kanji.

8. A node merely opened on a stale device reset that node's crown to 0 everywhere. markNodeSeen bumped updated_at with crown = 0 under whole-row last-write-wins. Verified by replaying both upserts. It no longer touches the timestamp of a row that exists.

9. "Delete Course Progress" was undone by reopening a node — the upserts cleared deleted_at while leaving crown/cracked_at, so a deleted course came back fully crowned, and that resurrection pushed to the other device.

10. A test file under app/ broke the web export. expo-router's require.context bundles every .tsx under the app root as a route, so vitest→vite entered the web bundle and Metro died on import(filepath). Found by the failed Vercel deploy on this PR, confirmed in expo-router's source. Moved to test/learn-node.test.tsx.

Also fixed

  • Generate was enabled before the decomposition loaded, so a paid call could go out with primitives: [] against an instruction to weave them — and the useless story was cached under that frame's key.
  • A failed note read left loaded false forever, so the keyword override was silently discarded for the life of the mount — and the TextInput mock dropped onChangeText, onSubmitEditing and onBlur, so nothing covered it.
  • AssembleDrill built its tap list from a stale closure: two taps in one batch lost the first and scored a miss for the right order.
  • A fully crowned node told the learner the feature was unfinished.
  • check-safe-inserts.sh, which I loosened last round into a window that could borrow a later statement's ON CONFLICT, now stops at the statement. An unsafe one-liner is caught again.
  • recordConfusion never set updated_at, and confusion_pairs pushes on it — so every pair the drill wrote was invisible to the other device. Pre-existing on master; this PR added a caller and claimed the opposite in prose.

My own claims, corrected

The fourth reviewer was pointed at the commit messages and the PR body, and it was right about all of this:

  • "292 tests across 20 suites" was mislabelled. The course's own 16 files hold 232 tests. The full suite is 2,260 tests, 0 failures.
  • The prove-fail count does not add up: the commits claim seventeen where the body says eleven, and one says "three ways" then lists four.
  • One claimed prove-fail could not fail. Deleting the no-strokes dropStep left both tests green, because the only observable difference is the header count and nothing asserted it. Now asserted.
  • The test pinning "7 frames have no lookalike" asserted that an array was an array. It now measures all 2,200 frames; dropping the lesson filter fails it.
  • 9.2 lookalikes on average → 8.96. 280 unlinkable edges is DB-wide → 232 on the path, and they do not explain the whole shortfall (6 of the 165 have no decomposition rows at all). A comment said 244 invented primitives → 233. The plan claimed two deep links into a node that do not exist.

Not mine, but it was blinding the merge

stores/settings.test.ts has had CI red on master for five OTA cycles: defaultSettings gained readerHighlightExcludedListIds in 8d1a061 and the test's expected object never did. One line. Fixed here, so the suite is green and the signal on this PR means something.

Left open, deliberately

  • If the remote CREATE TABLE ever fails, that table silently never syncs again, and a later Hard Sync deletes the local rows and pulls nothing. Pre-existing in ensureRemoteSchema/ensureColumnCache (the version advances even when a statement throws; an empty column list is cached permanently); my table inherits it. Not touched here — it is a sync-engine change that deserves its own PR.
  • Foreign keys are off on device (PRAGMA foreign_keys is only set in tests), so ON DELETE SET NULL on srs_cards.list_id never fires in production. Pre-existing.
  • myWords is no longer plumbed at all, which is the honest state: primitive_note_assoc maps word → targets and the reverse lookup does not exist.

Round 2 next, on the same four surfaces.

Do not treat a failed note read as an empty note.

If the read fails for a frame with an existing story, this sets loaded to true after clearing mnemonic. A subsequent saveKeyword passes that null mnemonic to upsertOrDelete and overwrites the stored story with an empty string. Keep edits that depend on the existing note disabled until a read succeeds, or make keyword-only writes preserve the stored mnemonic.

A soft-deleted card blocks re-graduation because its deterministic ID is still in use.

The card ID is derived from the unit and the literal. A soft-deleted card still holds that primary key. alreadyCarded skips soft-deleted rows, so graduation tries a new insert. onConflictDoNothing() drops that insert without an error. The frame is still reported as added, but no active card exists.

  • lib/rtk-graduate.ts#L119-L141: When the existing row is soft-deleted, use onConflictDoUpdate to reset its scheduling fields and set deletedAt to null.
  • lib/rtk-graduate.test.ts#L104-L110: Assert cards("二") equals 1 after re-graduation.

Every suite on this branch tests one piece. None of them could make the claim
the PR actually makes — that a learner who drills a node comes away with cards
they can study — and that claim was false for the whole of this branch's
history, because the membership test and the seeding disagreed and nothing
joined the two up.

This runs the real seeding against the real dictionary, the real queue and the
real graduation: lesson 1 arrives with its 15 entries and no cards; a crown-0
pass asks meet for all five frames before anything else and twenty items in
all; finishing it awards crown 1 and leaves five studiable cards; three crowns
leave one card each and a fourth visit has nothing to ask; and a crown the
learner deleted is not handed back.

Also verified rather than argued: a pass cannot be finished by missing
everything. Two hundred consecutive misses on a one-frame node, and five
hundred on a five-frame node, leave the queue exactly as long as it started and
nothing cleared — so clearing a last-item miss (the fix for the forever-re-ask)
cannot buy a crown.

Prove-failed: putting graduation's membership test back on list_entries fails 8
of these 14.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The surviving round-2 reviewer (two died on a weekly API limit) found six, and
three of them were regressions I introduced yesterday fixing round one.

A WRONG LAST ANSWER COULD BUY A CROWN. Fixing the forever-re-ask, I cleared a
missed last item into `cleared` — which is the crown gate. The reviewer executed
the sequence: a one-frame crown-2 node with no strokes tier drops to
[identify, cloze]; miss identify, the storyless cloze skips itself, miss
identify again, and it is now the last item, so it clears. Two wrong answers,
crown 3, cards made. My own check of this missed it because I only tried
missing EVERYTHING, which never shrinks the queue. The item now goes to
`skipped`, and I have pinned the reviewer's exact sequence.

A FAILED NOTE READ DESTROYED THE SAVED STORY. Setting `loaded` in the catch —
my fix for "the keyword is permanently unsaveable" — defeated the guard it was
meant to serve: the keyword path then wrote `saveNote(mnemonic ?? "")` with a
mnemonic it had never read, blanking the story, and if the keyword matched
Heisig's it soft-deleted the whole row on every device. There is now a
keyword-only write that touches no other column, and `readFailed` says plainly
that null means unknown rather than none.

DELETING THE !strokesDb SKIPS REINTRODUCED THE DEAD END. Those branches were
the only exit when the handle is lost AFTER being present, which is exactly the
case the dropStep guard refuses to drop. Waiting is only right while the handle
is there; without it the step is handed back.

Also: a rejected save still advanced the queue and reported the frame as met,
with the learner's text gone and the Save button dead — it now stays put and
says so; the one-shot award guard was a boolean reset by a sibling effect, so a
stale session could award and then block the real pass from ever awarding, and
it is now keyed to the node it awarded; and a story arriving while the learner
was writing their own replaced it, which only Regenerate — an explicit ask from
inside the editor — is now allowed to do.

Confirmed complete by the same reviewer: the keyed SkipStep, the assemble tap
ref, the crowned-node summary, and the removal of IMPLEMENTED_STEPS.

Gates: typecheck, lint (0 errors), check-safe-inserts, 2,267 tests across 128
files, 0 failures. Prove-failed: allowing an arriving story to replace the
draft (1 fails), and the crown sequence above.

Round 2 — and I am stopping the loop here

Two of the three round-2 reviewers died at launch on a weekly API limit (resets Oct 6, 08:00 SGT), so this round is one deep review of the React/runner surface plus verification I did myself. That is the reason the loop stops, not a judgement that nothing is left.

Three of the six findings were my own round-1 fixes

1. A wrong last answer could buy a crown. Fixing the forever-re-ask, I cleared a missed last item into cleared — which is the crown gate. The reviewer executed the sequence: a one-frame crown-2 node with no strokes tier drops to [identify, cloze]; miss identify (re-queued behind cloze), the storyless cloze skips itself, miss identify again — now the last item, so it cleared. Two wrong answers, crown 3, real SRS cards made.
My own check of this missed it: I only tried missing everything, which never shrinks the queue (verified: 200 and 500 consecutive misses leave it full). The item now goes to skipped, and the reviewer's exact sequence is pinned as a test.

2. A failed note read destroyed the learner's saved story. Setting loaded in the .catch — my fix for "the keyword is permanently unsaveable" — defeated the guard it existed to serve. The keyword path then called saveNote(mnemonic ?? "", …) with a mnemonic it had never read: the story was blanked, and if the keyword happened to match Heisig's, upsertOrDelete(null, null) soft-deleted the whole row on every device. Reachable on web by a cross-tab OPFS lock release, then tapping the keyword and tapping away — blur commits.
There is now a keyword-only write that touches no other column, plus a readFailed flag so null means unknown rather than none.

3. Deleting the !strokesDb skips reintroduced the dead-end spinner. Those branches were the only exit when the strokes handle is lost after being present — exactly the case the everHadStrokes guard deliberately refuses to dropStep. Waiting is only right while the handle exists; without it the step is handed back.

The other three

  • A rejected save still advanced the queue and reported the frame as met, with the learner's text gone and the Save button permanently dead (saving was never reset, and .finally ran on rejection). It now stays on the frame and says "That did not save. Try again."
  • The one-shot award guard was a boolean reset by a sibling effect. The loader effect runs first in a flush, so a stale session could award and then block the real pass from ever awarding — a whole pass drilled for nothing, reported as "Crowned". Keyed to the node it awarded.
  • A story arriving while the learner was writing their own replaced it. Only Regenerate — an explicit ask from inside the editor — may do that now.

Confirmed complete by the same reviewer: the keyed SkipStep, the assemble tap ref, the crowned-node summary, and the removal of IMPLEMENTED_STEPS/startSession's only.

What I verified myself, since two reviewers could not

test/rtk-course-end-to-end.test.ts — no mocks, real seeding against the real dictionary, real queue, real graduation:

  • Lesson 1 arrives with its 15 entries and zero cards.
  • A crown-0 pass asks meet for all five frames before anything else, twenty items in all.
  • Finishing it awards crown 1 and leaves five studiable cards.
  • Three crowns leave one card each; a fourth visit has nothing to ask.
  • A crown the learner deleted is not handed back.
  • 461 nodes over volume 1; lesson 1 is three nodes of five.

Putting graduation's old membership test back fails 8 of those 14. So yes — a learner can finish a node, earn a crown, and study the cards today. That was the question I most wanted answered and no reviewer got to it.

Gates

yarn typecheck clean · yarn lint 0 errors · check-safe-inserts passes · 2,267 tests across 128 files, 0 failures — the whole suite, green, including the stores/settings.test.ts drift that had master red for five OTA cycles.

Still open, and deliberately not fixed here

  • If a remote CREATE TABLE ever fails, that table silently never syncs again, and a later Hard Sync deletes the local rows and pulls nothing. Pre-existing in ensureRemoteSchema/ensureColumnCache; my table inherits it. It is a sync-engine change and deserves its own PR.
  • Foreign keys are off on device — ON DELETE SET NULL on srs_cards.list_id never fires in production. Pre-existing.
  • Graduated cards can still duplicate across two devices that crown the same node while both offline, because srs_cards for default lists push but list_entries do not and there is no unique index on (list_id, kanji_literal). Mitigated by deriving the ids — two devices now write the same primary key — but not provably closed.
  • myWords is not plumbed at all, which is the honest state: primitive_note_assoc maps word → targets and the reverse lookup does not exist.
  • No course panel on the stats screen; the path screen itself has no test.

Judgement

Round 1 found 20+ defects; round 2 found six, half of them mine. That is not yet a clean convergence — but with two of three reviewers unable to run until Oct 6, another round would be me reviewing my own work, which is what the adversarial reviewers were for. Merging on round 1 + round 2 + the end-to-end verification, with the open items above recorded rather than buried.
