Answers the two questions owed: the readiness shrinkage, the three
groupings, the priority ranking, and the four steps of adaptive
selection — including where it is weaker than it looks.
Writing it up surfaced two defects, both fixed here:
* adaptive_select took the first 2,000 candidate rows. The bank is
2,948, so about a third of it could never be selected, and which
third depended on database order. The cap is gone; two integer
columns per question is not a size worth protecting against.
* category lookup was a linear scan through every candidate for every
recorded answer — O(answers x candidates), the slowest part of
building a session. It is a dict now.
Left alone and documented instead, because changing them changes which
questions a learner is given and that is not a silent decision: adaptive
ordering uses raw category accuracy rather than the shrunk readiness the
recommendations page uses, and difficulty is a filter rather than
something the session moves along.

An unsuspended exam keeps running. When its clock runs out it is
submitted with what was answered and the score counts — a learner who
ran out of time sat an exam, which is a result and not an accident to
hide. Previously it was graded, flagged expired=1, excluded from every
statistic, and the client was told the opposite ("submit manually").
- attempt_expiry.settle_if_expired: one path, used by resume and by the
sessions list, so an exam left open elsewhere shows its score rather
than "in progress" forever. Suspended attempts hold their clock and
never expire.
- resume returns {expired_submitted, attempt_id}; the client opens the
analysis. The suspend dialog and the leave warning now say what
actually happens.
- delete: saved progress and device lock cleared; a study-plan block
whose only completed attempt is deleted goes back to unfinished.
- POST /attempts/reset-all: typed RESET, removes attempts, answers,
in-progress state, plan progress, reading marks, saved questions and
question notes; leaves the account, authored content and AI chats.
Settings → Your data, with the counts reported afterwards.
Also fixed on the way: the first version of the sessions-list change
mutated the dict it was iterating; the test only passed because it had
one attempt. Now two.

The linking was the gap
The marker system was built weeks ago — resolves by id, survives a rename, shows
a preview on hover — and not one of 333 articles used it. Every article was
written in isolation, so a piece on croup named stridor and epiglottitis and
offered no way to reach either. `scripts/link_articles.py` reads what is written
and links it: 3,718 cross-references across 307 articles, by id, so a later
rename cannot break them.
Conservative on purpose, because a wrong link is worse than a missing one: only
the first mention in a section, whole words, longest title first so "Otitis media
with effusion" beats "Otitis media", never inside an existing link, marker,
heading, code span or table, and never an article to itself.
That exposed a second thing: the reading view had its own Markdown pipeline with
its own cross-reference regex, and it only understood the old slug form. It would
have printed every one of those 3,718 links as literal brackets. Article prose
now goes through the same renderer as the rest of the site.
Short and Clinical looked empty
Both are usually a single section, and everything starts collapsed, so the tab
showed one heading over blank space. A view of one section is not a contents
page; it opens.
Removed
Quiz reminders — emailed nudges to retake anything under 75%, with a scheduler
that existed solely to send them: the model, the service, the scheduler, the
email, the table. Article comments. The dashboard's in-progress list and its
stat cards, both of which the analysis page now answers better.
One mistake worth recording: the first pass at removing the reminder cleanup used
a regex that took 109 lines with it, including an unrelated endpoint. The test
suite caught it (`/attempts/quiz/{id}/in-progress` returning 404 instead of 403),
and the file was restored and edited by exact match instead.

Every link from the history went to /quizzes/:id, which auto-started. Clicking
"Board Review IX" out of curiosity began a 243-question exam, clock running.
That is why the links looked broken: they worked exactly as built, and what they
did was wrong.
Landing on a session now shows it — mode, length, and what the clock does — and
starts when asked. The session rows and the analysis rail open the session's own
analysis rather than the raw answer list, which is what a rail of past sessions
is for.
Sessions carry no category, so the row no longer prints one; that field was
still showing the retired "PREP" label.
Twenty tests asserted the old behaviour by mounting the player and waiting for
the stem. They now start the session the way a person does, which is the point:
the assertion was encoding a bug.
Settings is on the list. Before restyling it, the question is what belongs there
at all — several things have drifted in because there was nowhere else to put
them.

Figures
A question could carry exactly one stem image and one explanation image, each a
bare path with no title, no legend, and no way for the prose to refer to it.
`question_media` makes a figure a row: it points at an image already in the bank,
carries a role, a label the text can name ("Figure 1"), a caption and an order,
and there can be as many as the question needs. The same radiograph can serve two
questions without being stored twice.
The 346 existing paths were backfilled into figure records and retitled —
`page_339_img_0.png` says where a file came from and nothing about what it shows,
so the filename moved into the caption where it is still searchable, and the
title became something a person can read.
On the editor question: no new platform needed. Milkdown is already installed —
ProseMirror-based, MIT, GFM tables, code blocks, LaTeX — and already used for
articles, courses and the quick question modal. Only the question *page* still
has plain textareas, and that swap is written down rather than rushed, because
the stem carries manual-highlight offsets and a WYSIWYG rewrite would move them.
Fewer hints during a quiz
The category trail and the difficulty pill were shown beside every stem. Being
told a question is filed under Neonatology, or that it is "hard", narrows the
answer before the stem has been read. Both now wait until the answer is in,
where the trail becomes a way to more of the same topic.
The dashboard is about questions
Quizzes and attempts describe how the material happens to be packaged. What a
learner is working through is questions: how many of the bank they have seen,
how many they have answered correctly, and their average. The old per-quiz
performance card — which needed two attempts before it showed anything — is
gone, superseded by the session analysis. The greeting sits above "continue your
study" rather than below it, where it read as a heading for the wrong section.

The results page showed a score and a wall of explanations. What a learner needs
afterwards is where the time went and what to go back to, so
/analysis/session/:attemptId gives them: a rail of recent sessions, the four
figures they act on — correct, completed, time per question, total time — a
donut, the weakest topics, and a paginated table of every question with its
status, difficulty, time and how peers did on it.
Time per question was not recorded at all, so it could not be reported. It is
now (`attempt_answers.seconds_spent`), banked when you leave a question and
including the one still open at submission — without that the last question of
every session would show nothing. Answers from before this read "—" rather than
claiming zero, and a question nobody else has answered has no peer rate rather
than 0%, which would read as everyone having failed it.
Also in this pass, from the review:
* quiz categories are gone from the library — a second taxonomy beside the
real one, putting a heading above every test;
* the board review sets are numbered rather than dated, in both the quizzes
and the study plans built from the same material, so a learner does not meet
2019 in one place and VII in another;
* the footer's standing note is one clause, and the gap above it no longer
looks like the page ended early.
Everything else asked for today is written down in docs/TODO.md rather than
half-built: resume instead of restart, an unsuspended exam that keeps running,
deleting a session's data, reset-all-data with a warning, recommendations split
by article/discipline/system, and the adaptive session. Two questions I owe
answers to are in there too.

The design settled earlier, built as described: retrieval decides what may be
cited, and the server enforces it.
The model is handed a shortlist of at most fourteen sources from the learner's
own library and told to cite them by marker. Afterwards every citation it wrote
is checked against that shortlist and anything else is deleted before it is
stored or shown. A hallucinated citation is not unlikely here, it is impossible
— surviving is not a decision the model gets to make. A URL it invents is not a
citation either: only the marker form counts, so a plausible-looking link stays
in the prose citing nothing.
Retrieval reuses the hybrid search already in place, and each corpus keeps its
own visibility rules — the bank predicate and exam scope for questions, the
draft rule for articles, deck ownership for cards. A question source carries the
stem only: a chat that printed the answer would hand away the practice it exists
to prepare you for.
Curated links do the job they were built for. A retrieved row an educator tied
to another retrieved row is boosted, because two things somebody already linked
surfacing for one query is evidence rather than coincidence. Nothing is stored
for this; the boost lives only in that ordering, and the answer marks those
sources so the reader knows which claim rests on an educator's judgement rather
than on a ranking.
Citations are stored with the answer as filtered, so reopening a thread shows
the links it showed at the time rather than a fresh retrieval that may now rank
differently. In the page the markers become numbers and each number opens its
source; a section citation deep-links into that section.
Two smaller decisions worth naming: a question appears in the thread the moment
you send it and is handed back to the input if the answer fails, because typed
words are not something to lose on a 502; and someone else's thread returns 404
rather than 403, since whether it exists is not your business either.

Thirteen plans were seeded with an API to serve them and nothing that called it,
so the whole feature existed only in the database. Two pages and the editing
endpoints it was missing.
/study-plans lists the plans with progress stated in blocks — "3 of 6 blocks"
is something you can act on, where "50%" only tells you how you feel about it.
/study-plans/:id is one plan: each block shows Articles, then Sessions, in that
order, because that is the order the block is meant to be done in.
Reading is now part of a block (migration f4a5b6c7d8e9). "Mark as read" is the
learner's own claim and reversible — someone who ticks the wrong row should be
able to fix it without an educator, and progress nobody can correct stops being
trusted and then stops being used. It is a separate table from `article_views`
on purpose: opening an article is not the same claim as having finished with it.
A draft article attached to a block is listed for the educator who can open it
and left out for everyone else, rather than offered as a dead link.
Editing is inline on the learner's own page rather than a separate builder, so
the thing being changed and the thing a learner sees are the same object.
Moderators create (as a draft — an empty plan is not something to put in front
of anyone), rename, publish, delete; add, rename, reorder and remove blocks;
move questions between blocks of one plan; attach reading found by searching
rather than by id.
Two places where the obvious implementation leaves the data wrong, both tested:
deleting a block out of the middle shuffles the survivors down, or the next
insert collides with a position nothing occupies; and reordering parks every row
outside the range before writing the real positions, because (plan_id, position)
is unique and the first move would otherwise collide with a position still held.
A partial order is refused rather than half-applied.

The media API has existed since the image-libraries work with nothing to call
it, so images could be uploaded but never described, tagged, or found again. Two
screens close that.
/media browses the bank by library, searches by what an image shows, and edits
title, caption, alt text, tags and library in place. The id sits on every
thumbnail rather than appearing on hover, because the id is what a question
refers to and you should not have to go looking for it. An image with no caption
says so — captions are what the search index is built from, so an undescribed
image is one nobody will find, and that is worth saying on the card rather than
in documentation.
The question editor asked for a filename typed from memory, which meant keeping
a second tab open or guessing. It now opens a picker over the same bank, showing
caption and tags on every result: two chest films are identical at thumbnail
size and the caption is the only thing that tells them apart. An image uploaded
from the picker goes straight onto the question — coming here to add a picture
and then having to find it again is a step that exists for nobody's benefit. The
"Browse image bank" link pointed at /images, a route that does not exist.
Permissions follow the API rather than reimplementing it: library creation and
deletion stay with moderators, describing an image does not, and an upload goes
into the library being browsed because a non-moderator must name one.

Five corpora were each searchable from their own page, which meant knowing which
of five pages held the thing you were looking for before you could look for it.
`GET /search` runs them together.
Visibility is never re-implemented here. Questions go through the same bank
predicate and exam scope as the question bank, articles through the same draft
rule, cards through deck ownership, images through library grants. A search page
with its own idea of who may see what is how private content leaks, so the tests
that matter are the boundary ones: a peer's search reaches neither another
user's unshared question nor their deck, and a draft is invisible to everyone
but the educator who wrote it.
A section hit is reported under its article, not beside it — ten sections of one
article are one result with ten places to start reading, not ten results burying
everything else. This is what the section index was backfilled for; each one
links straight to that section.
Results are grouped by kind rather than interleaved by score. A question and an
article are different kinds of answer, and a single ranked list makes you read
every row to work out which kind each one is. Snippets show the window around
the match rather than the opening of the document, because every document's
opening looks the same. A question found only by the semantic ranker says so.
The header box has two ways out: pick a suggestion and go straight to that
article, or press Enter and search everything. Suggestions are lexical and
prefix-first — a typeahead is finishing the word you are typing, and a semantic
neighbour of half a word is noise — and debounced 180ms so typing is not a
request per keystroke. One corpus failing is logged and returned as a gap in the
answer rather than a failed page.

Three things, all from how AMBOSS actually behaves rather than from a
description of it.
Row by row, two menus
The articles page is now the column browser itself rather than a grid behind a
"▼ All categories" toggle. Opening a topic opens its contents in the next
column, so the trail you took stays on screen and you can step back a level
without losing your place. Topics and the articles filed under them share a
column, because to a reader those are the same list — things this heading
contains — and only the icon separates a folder you can open from a page you can
read. Articles filed nowhere sit in the root column instead of being unreachable
for want of a heading. Under 720px it is one column plus a back button. Search
is a different question from browsing — you already know the name — so it still
answers with a flat list of matches.
Sections that collapse
An article is a reference you consult, so it opens as a contents page: headings
only, each expanding where it sits. A section may now sit under an earlier
top-level one (`parent_id` on the section JSON, absent on every article written
before this), which is how "ROS questionnaire" belongs to "Review of systems"
rather than standing alongside it. The contents rail nests the same way. Nesting
is refused where it could not render: its own parent, a parent later in the
article, a parent outside it, or a sub-section of a sub-section. A deep link
opens the target section and its parent — landing on a collapsed heading looks
like the link went nowhere. References are pinned last however they were
written; a reader scrolling for content should not hit the bibliography halfway
down.
Links that show where they go
`[[febrile-seizures]]` or `[[Febrile seizures|febrile-seizures]]` in article
prose becomes an in-app link that previews the target on hover: title, a couple
of sentences of actual prose with the markup taken out, and how much is there.
Following a link to find out whether it was worth following is the thing that
breaks a train of thought. Slugs, not ids, because that is what an educator
writes and it outlives a renumbering. One fetch per article for the life of the
page, a 350ms delay so crossing a link summons nothing, and no card at all on
touch, where a card would sit between the finger and the link.
Dead CSS for the old section modal and the always-open section block is gone —
nothing rendered those class names any more, and stale rules winning on source
order has bitten this page before.

Storage
Media now goes through `storage_service`, which has two backends: the container
volume, and S3/MinIO. A volume can only be mounted by one host, has no presigned
URLs and no lifecycle rules, none of which suits ~860 MB of media. Reads fall
back to the volume when an object is missing, so the existing uploads keep
working and files can migrate gradually rather than in one risky pass.
A row stores the object key, never a URL: a URL embeds the backend, so a row
holding `http://minio:9000/...` breaks the moment the backend changes.
MinIO publishes no host ports — the backend reaches it over the compose network,
and 9000/9001 are already taken on this host by other stacks.
Image libraries (migration d2e3f4a5b6c7)
An image belongs to a library, and a person is granted a library the way they are
granted a category, so access can be given to some images without giving away all
of them. Tags reuse the shared `question_tags` vocabulary rather than inventing a
media-only one. Uploads are type- and size-checked, stored through the service,
and embedded so an image can be found by what it shows.
Classification finished
The 316 questions the chooser had declined are now filed with `--force`, which
takes the nearest candidate from the same shortlist the chooser saw. 306 were
forced, 10 the chooser accepted on this pass. No question sits on a bare system
any more:
system only 2,730 -> 0
condition/subsystem 214 -> 1,782
full depth 4 -> 1,166
A forced match is a weaker signal than a chosen one, so expect more errors among
those 306 — but the original system stays as a cross-link, so nothing is lost and
they can be corrected by hand.
Tests: 8 new backend covering library scoping, edit confinement, shared-vocabulary
tags, storage indirection on upload, and type/size limits. 131 backend green.

1,486 questions had a top-level system as their primary category with no
condition to promote — General Pediatrics alone held 396 and has no
subcategories at all, so its questions are almost always about something that
already exists elsewhere in the tree.
Two stages, same discipline as the AI-mode citation contract: retrieval ranks
existing categories against the question's stored embedding and keeps the nearest
eight; a chooser picks one of those or says NONE. The model never sees the whole
tree, never writes a category name, and anything not on the shortlist is
discarded — so a category it invents cannot survive. Nothing new is created:
questions are filed into categories an educator already has.
1,170 filed, 301 declined by the chooser, 15 with no candidate above the
similarity floor. Filing depth across the bank:
system only 2,730 -> 316
condition/subsystem 214 -> 1,596
full depth 4 -> 1,036
A spot check found roughly three in four correct — a question about an ADHD
medication refill was filed under Obesity. That is acceptable only because the
original system is kept as a cross-link on every moved question, so a wrong pick
narrows nothing and never loses a question. Recorded in the TODO for an
editorial pass.

93% of questions had a top-level system as their primary category, so the
condition tree was reached almost entirely through cross-links: every deep node's
count was a link count, and a question about Tetralogy of Fallot read as
"Cardiology" rather than as what it is about.
Where a question already linked to a condition inside its own system, that link
was the specific classification, so it becomes the primary and the system is kept
as a cross-link — nothing narrows. 1,244 promoted, leaving 1,486 at system level
rather than 2,730. Destinations check out: VSD under Congenital Heart Disease
under Cardiology, Pertussis under Bacterial Infections under Infectious Disease.
Where several candidates existed the deepest won, breaking a tie on question
count; 31 that tie on both are left alone rather than resolved arbitrarily.
1,455 questions have no condition inside their own system at all, so there is
nothing to promote — they are genuinely unclassified below the system, worst in
General Pediatrics (396, which has no subcategories at all), Emergency Medicine
and Adolescent Medicine. That needs classification work, not a data move, and is
recorded in the TODO rather than guessed at.
The one uncategorised question was the seeded febrile-seizure demo; it is filed
now, so all 2,948 resolve to a system.

Nesting (scripts/nest_systems.py)
The tree was 27 systems and ~1,050 conditions, one level deep — a flat
alphabetical wall in the Systems picker. It is now System → Subsystem →
Condition: 69 subsystems, 305 conditions nested, 564 left directly under their
system because forcing an approximate bucket is worse than leaving them.
Subsystem names are standard textbook divisions, each matched by an explicit
pattern so a dry run shows exactly what moves. Three false positives the dry run
caught were fixed before writing: "erythema" was pulling Systemic Lupus
Erythematosus into dermatology, and a bare "meconium"/"aspiration" was filing
Meconium Ileus as respiratory and Meconium Aspiration as foreign-body.
One home per condition (scripts/merge_duplicate_conditions.py)
The tag→category conversion made each question's subject tag a parent, so a
question tagged Pulmonology and Emergency Medicine produced an "Asthma" row under
each. 330 of 618 condition names lived in several systems — Sepsis in seven,
Failure To Thrive in eight — so no filter ever added them up.
216 names are now folded into the row holding the most questions, and the other
systems survive as `question_category_links` on each moved question: a link is
how "this matters to nephrology *and* emergency medicine" is meant to be said,
duplicate rows are not. 347 rows removed, 1075 → 786, all 2,948 questions intact.
114 names are an even split across systems. Those are reported, not merged —
picking a home for Pneumonia between Pulmonology and Infectious Disease is a
medical call, and an arbitrary tie-break would bury it.
Both scripts are idempotent and were applied after table backups.

Category duplicates
The tag→category conversion appended a parent name to keep labels globally
unique, so the tree was full of rows like "Cellulitis (Emergency Medicine)"
filed under Emergency Medicine. The breadcrumb already shows the parent, so the
suffix was noise in every picker. scripts/sanitize_categories.py strips it,
then merges siblings that collapse to the same name — including the
"Absence Seizure" / "Absence Seizures" pair. Applied to production after a
table backup: 491 renamed, 3 merged, 1078 → 1075, and a second run is a no-op.
Merging repoints questions, additional-category links, articles, decks, child
categories and grants before deleting the losing row.
Newly created categories not appearing
`/api/question-categories` (no trailing slash) 307-redirects to **http://**,
which the browser blocks as mixed content on an https page. Three callers used
the bare path, so the request failed silently into a catch and the list stayed
stale. Trailing slash added.
Category page
Rows now show questions filed directly here, the roll-up including everything
beneath, subcategory count, and an Empty badge for a leaf holding nothing — so
the shape of the tree is visible rather than inferred. On small screens it says
plainly that editing is easier on a desktop.

A discipline may now belong to one exam. `question_tags.exam_id` NULL keeps a tag
shared — Cardiology means the same thing whichever exam you sit — while a set
exam_id scopes it. Boards Pediatrics and a future Step 1 Pediatrics are therefore
separate rows over genuinely different bodies of content, not one label stretched
across both. Uniqueness moves from (name, type) to (name, type, exam) to allow it
(migration b0c1d2e3f4a5).
`scripts/bind_exam_tags.py` binds Pediatrics to Pediatrics Boards and tags the
884 questions in that exam that were missing it — the whole bank is paediatrics,
so it now reads 2,948.
Facet counts are computed within the learner's active exam, and a tag scoped to a
different exam is left out: an unscoped list offered disciplines that could not
match anything they were studying. With no exam chosen, everything is offered as
before.

Editing a question now snapshots its previous state. The last 5 are kept — the
value is undoing a recent mistake, not an audit trail, and an uncapped history of
full question bodies grows without bound (migration a9b0c1d2e3f4).
A restore snapshots the current state first, so the restore is itself undoable.
History is gated by the same per-category grant that gates editing, so it cannot
be read by someone who could not have made the edit. The question editor shows
the versions with their dates and a Restore action.
Also added docs/TODO.md tracking everything requested and not yet delivered:
AI Mode and its citation contract, global search, study-plan editing and
articles-in-blocks, admin settings revamp, image libraries and question folders,
media management, nested article sections with references and per-section notes

Create/bank pages use AMBOSS-style facets: Exams, Disciplines, Symptoms, Systems, Articles, Saved. Personal question libraries with add-to-library in study modal. Adaptive session shortcuts from performance (including weakest topics). Quiz restart with fresh attempt. Category counts computed with two grouped queries. Migration n7a8b9c0d142. 63 backend and 97 frontend tests pass.
Tutor questions require owned selected attempts; similarity context filters eligibility before ranking. Uploads move to a permission-aware boundary with reference ACLs, canonical legacy aliases, pre-mutation attachment checks and card-aware moderator rules. Nginx stops caching media and supplies native byte ranges. Verified 37 deployed-image backend tests, 69 frontend tests/build, real pgvector/Nginx/browser checks, and two independent reviews.
Remove the challenge from standalone and landing login plus backend verification; retain registration/contact protection and existing password, email verification, SSO and login rate-limit checks. Verified 18 backend tests in deployed image and 17 frontend tests plus build.
