Two removals the user asked for.
No deck from a PDF section. A card should be written from an article —
text a person has read, edited and published — not from whatever
happened to be on pages 40-58 of a source document. POST /flashcards/
and the generate_flashcard_deck task are gone, with the Create Cards
button on the document page. What remains: POST /articles/{id}/ai-cards,
and POST /flashcards/manual for writing a deck by hand.
And no Nextcloud. It was a per-person cloud integration for a corpus one
person loads: a settings panel asking every educator for an app
password, a second tab on the upload page, and three endpoints. The
upload page now has one way in, which is the one anybody used.

Opening any shared deck answered 500 — ResponseValidationError, "Input
should be a valid integer" for user_id. The ownership migration made
those columns nullable and the response models still declared
`user_id: int`, so the first read of a deck after it was a crash rather
than a page. A learner hit it on Cards.
FlashcardDeckResponse, DocumentResponse and QuizResponse now allow None,
with a test that walks the three and fails if any of them promises an
owner again. The grant-input schemas were left alone on purpose: their
user_id names the person a grant is for, and a grant with nobody in it
is not a thing.
Also gone: send_login_code_email, forty-eight lines of email template
for a feature that no longer exists.

571 categories, 21 uploaded documents, 14 articles, 8 card decks, 30
shared tests and 2 questions carried somebody's name — mostly
daniel@danvics.com, which is not even the working administrator any
more. So "who may edit this" partly depended on who happened to create
it, and handing the site to somebody else would have meant rewriting
every one of those rows.
Migration q6a7b8c9d0e1 empties those owner columns and makes them
nullable, because ownerless is now a legitimate state and a NOT NULL
owner is exactly what forced a name onto every row. Nothing is deleted
and nothing moves. What keeps its owner, deliberately: attempts, notes,
favourites, collections, folders, study-plan progress, and the quizzes
that are somebody's own sittings rather than shared bank tests.
study_plans needed nothing — it never had an owner column.
Then the code, so it cannot grow back. Authorship is no longer a way in
anywhere: may_edit_question and can_edit_article ask the role and the
grants and nothing else; the article draft, status and delete paths lost
their "or you wrote it" arm; decks are the bank's, so an educator
reaches any of them and a learner reaches the shared ones; documents are
the corpus, so they are editors-only rather than "mine"; and every
creation path writes user_id NULL. The bank listing's "mine" facet went
with it — it counted nothing and could only ever count nothing.
Verified against production as a real learner account: every bank write
403s, admin settings 403, documents empty. As an admin, everything
opens.
Also: a category grant no longer offers Editorial in the menu. It offers
Questions and Images, which is what a grant covers; Editorial is the
whole library's review queue and its route is moderator-only, so the
entry was a door that answered "Not yours to open".
Six tests changed rather than deleted — they asserted the old model, and
each now asserts the new one: writing an article does not make it yours,
writing a question does not make it yours, an answer image is not opened
by authorship, the tutor is not opened by authorship.

Four things a deck got wrong.
The category. Every deck written from an article is filed where the
article is filed — and the list drew all of them "Uncategorized",
because the router defines its own FlashcardDeckResponse that shadows
the one in schemas/, and that one has no category_id. So the field was
set on the row, returned by nothing, and an educator refiled by hand
what the system had already filed correctly. The shared schema was
imported by no module at all, so it is gone rather than left as a
second definition to read past next time.
The size. Fifteen cards is the per-chunk default, and an article is one
chunk however long it is — a ten-section piece and a two-paragraph stub
both asked for fifteen. Now roughly a card per 150 words, floored at 12
so a short article still makes a deck and capped at 30 so one call stays
inside the model's output.
The card. Set at list-item size inside a frame that fills the window, so
a two-line question sat in the middle of an acre of white. The face
scales with the window and stops at a comfortable measure; the back is
set smaller than the front, as prose rather than a headline.
And the contract snapshot, which still owed the jobs endpoint from the
last commit.

**Two sources an AI draft can draw on**, both off until an administrator turns
them on, both appended to the prompt as extra material rather than woven into
it — so a draft with nothing to draw on is byte-for-byte the draft that has
been working well.
- *The clinical library.* The indexed shelf the clinical assistant already
searches, over MCP on the internal network. Ported from ped-ai: sessions are
reused, a dead one is reopened once, and a library that cannot be reached
never fails the article — it just means the educator is writing without it,
and the progress line says so.
- *PubMed.* NCBI's E-utilities, no key required. Ported whole, including the
two lessons that cost somebody an afternoon over there: PubMed ANDs every
term, so "bronchiolitis management in infants" can find nothing where
"bronchiolitis management" finds six — hence the query ladder — and three
esearch calls in a row will trip the rate limit, hence the spacing. The
reference list is written from the records rather than by the model, so every
line is a paper that exists with a PMID somebody can look up.
Measured on the live stack: 24 excerpts, 6 papers, 6 references, 6 in-text
citations, in one draft.
**The card system, which turned out to be half-built:**
- There was no way to make a deck by hand, and no way to edit a card at all —
you could browse, view and delete. Both are there now, the editor taking
front, back and a picture.
- Filing, writing, sharing and deleting are all educator work now, behind one
named gate rather than four scattered checks. A learner studies.
- A deck generated from an article inherits that article's category instead of
landing in Uncategorized for somebody to file by hand.
- A link inside a card previewed instead of going. A card is a box a few lines
tall, often inside a flipping panel, and a hover card anchored in one is
clipped by it — so the link read as broken because clicking it did nothing.
Where there is no room to preview, the honest behaviour is to take you there.
**An AI draft belonged to no editorial queue.** Nothing set `generated_by`, so
a drafted article was neither "generated, unread" nor anything else: the tile
counted it and there was nowhere to click. Drafts are stamped with the model
that wrote them, and there is now a plain Drafts queue that cannot be fallen
through.
**The sign-in code email** is laid out rather than written: the code is the
biggest thing on the screen, then which account it signs into, then a way back
to the page, then permission to ignore the whole thing.
Also: a back link out of a deck, in the same words as the rest of the app.

**Cross-references can name a section.** `[[264#workup|the workup]]` opens the
reader at that heading, which is what a sentence about one part of a long
article actually means. Whole-article `[[264|label]]` is unchanged, and a
section renamed since is not a broken link — it lands at the top of the right
article, which is a mild disappointment rather than a dead end.
**A picker that writes the marker for you.** 🔗 Link an article, in the editor:
type a few words, click the article — or one of its sections — and the marker
is on the clipboard with the right title as its label. Getting an id used to
mean opening the library in another tab, finding the article and reading the
number out of the address bar, which is four steps and a chance to mistype,
every time. Its own small endpoint, because the listing deliberately does not
carry sections and this needs nothing else.
**Three things about cards that were built but never drawn:**
- A card can carry an image. The column is there, the API returns it, the
editor accepts one — and no view in the app rendered it, so every picture
anybody attached to a card was stored and never seen. Both card views show it
now, small until clicked like every other figure.
- The deck browser printed `[[331|Epiglottitis]]` as brackets and a number. The
study view has rendered them as links for a while; now both do.
- There was no way to make a deck by hand. Every deck came out of a model —
generated from a document section or an article — so an educator who wanted
to write six cards had nowhere to put them, and the add-a-card route could
only add to a deck that did not exist yet. `+ New deck` on the cards page.
**Generate cards ran in silence.** It starts a real job, and the only place its
progress was drawn was inside the refine panel — which lives in the editor and
is shut. Pressing it on the reading page did nothing visible for ninety
seconds. It now says what it is doing where it was pressed.
**Overlays were invisible to learners.** A stored width is a fraction of the
image, and the stroke is drawn with `non-scaling-stroke`, which makes
`stroke-width` a count of screen pixels — so 0.006 meant six thousandths of a
pixel. The editor has always multiplied by its rendered width; the viewer now
does the same sum. Every region an educator has ever marked was invisible to
everyone who was not editing it.
Also: the figure viewer no longer scrolls, at any width, and the page behind it
is pinned properly (`overflow: hidden` on the body does nothing on iOS, so a
figure opened half-way down an article drifted while it was read). Options are
full width on a phone. The question toolbar's seven glyphs are four, with the
rest folded into the ⋯ that was already there, spelled out in words. The jobs
popover closes on a click anywhere outside it. And the editor has a way back to
Editorial — "back to the article", from an article you opened to edit, is a
loop.
The contract snapshot caught both new routes on the way through, which is what
it is for.

Three things the card system did not have.
**Spaced repetition.** There was none. "Known" and "to review" were React state
that vanished on reload, so a deck of two hundred was two hundred cards every
time and the only spacing was whichever cards a learner remembered to skip.
Verdicts are now kept, and the deck comes back in the order the learner's own
history calls for: due first, most decayed first, then never seen, then the
rest — because somebody who has met the whole deck recently should still get a
deck rather than a screen saying come back on Thursday.
It borrows the question player's arithmetic rather than choosing its own.
`recall_probability`, `DUE_RECALL`, the thirty-day half-life: two schedulers
with two ideas of "due", in one product that shows a learner one readiness
number, is how the number stops meaning anything. Two outcomes and no
four-point scale — a scale asks a learner to rate their own recall in units
they have never calibrated, and the extra resolution is noise.
**Cards are prose.** Both faces go through the same renderer as everything
else, so a card can carry `[[264|respiratory failure]]`, a `==key point==`, a
teaching tip or a figure. That is most of what "link cards to things" turns out
to mean.
**A deck is reachable from the question.** Beside the topic-reading chip under
the correct answer, one chip per linked deck. Read from the question's end
only, deliberately: a card that listed the questions it belongs to would hand a
learner revising the deck the shape of the exam, and the answer with it.

Retrieval generalised beyond questions
`_text_for_question`, `embed_question` and `hybrid_question_ids` all hardcoded
the questions table, so there was nothing to call for an article or a card. That
layer is now corpus-agnostic:
- `Embeddable` mixin gives articles and flashcards the same embedding,
embedding_model and embedded_at columns questions have, plus a weighted
full-text vector (migration u3a4b5c6d7e8).
- `embed_record(row, kind)` is one code path for all three — they share an
embedding space, so they must share the model and provenance rules too.
- `hybrid_ids(db, query, kind)` ranks any corpus; `hybrid_question_ids` stays as
a thin alias for existing callers.
- Article and flashcard search moved off `ILIKE '%term%'`, which could not find
a jaundice article from "yellow newborn".
- The retry task and full regeneration now sweep every corpus, and the health
report breaks down current/stale/missing per kind.
- Articles embed on create and on edit, with failures left to the retry task.
Quoted phrases replace the keyword-only mode
`websearch_to_tsquery` already gives "absence seizure" exact-phrase semantics,
and the semantic ranker sits out a quoted query. That covers the one case a
keyword-only toggle was for — exact lookup — per query rather than as a sticky
setting whose every position returns a subset of the default.
Full-page question editor (/questions/new, /questions/:id)
Editing happened in a cramped modal. There is now a page with room for the stem,
per-option explanations, a searchable category picker with primary plus extras,
difficulty, and images. It shows the question's id with a copy button, and
Duplicate creates a variant without retyping the stem. `GET /questions/detail/{id}`
backs it, pathed under /detail/ so it cannot shadow the static routes.
Question bank filter bar restyled — the toggle and count read as one control
instead of two grey pills crowding the result count.
Tests: 101 backend green.

Questions and articles both pointed at `question_categories`; decks had no
category at all, so the three content types could not be filtered together and a
topic's cards were unreachable from its category.
- `flashcard_decks.category_id` references the same tree (migration
t2f3a4b5c697), so one category now spans questions, articles and cards.
- `GET /flashcards/` takes `category_id` and includes descendants, so a parent
category picks up everything filed beneath it.
- `PATCH /flashcards/{id}` files or unfiles a deck, refusing a category id that
does not exist rather than storing a dangling reference.
- The cards page shows each deck's category as a selector.
Tests: 5 new backend (all three types resolve to the same id, descendant
filtering, file and unfile, unknown category refused, renaming leaves the
category alone) and 1 new frontend. Full suites green: 101 backend,
136 frontend, build clean.

Escape raw HTML in article markdown, honor section deep links, filter card link listings by bank visibility and publication status, validate source sections. 44 backend and 77 frontend tests pass.
ai_decide now samples 4 points across the section (start, 1/3, 2/3, end)
instead of just the first 30 + last 20 pages. This gives accurate strategy
detection on large documents where the answer format might be deeper in.
New ai_answer extraction mode:
- Extracts questions from Q&A-format PDFs that have no answer key
- AI picks the correct option from each question's choices
- Generates explanation using document context + medical knowledge
- Useful for PDFs like practice tests where answers were never included
- Available manually and as an ai_decide strategy
Flashcard decks can now be renamed:
- PATCH /flashcards/{deck_id} updates title
- Inline edit on FlashcardsPage with responsive layout (input full-width,
buttons wrap under it so Cancel never overflows the card)
- Title truncates with ellipsis when not editing
Note: generate mode (textbook -> MCQs) is unchanged per user request.
