Both were this app doing an identity provider's work. Sign-in and
sign-up happen at sso.pedshub.com now: it takes the address, sends the
code, checks it, and knows about second factors — none of which belongs
here, and two of which were never done here at all.
Gone: services/invites.py, services/login_codes.py,
routers/login_code.py, the two models, the three admin invite routes,
the invite_only flag and its switch, the invite field on both sign-up
forms, and the code half of the sign-in page — which was the primary way
in and is now a button that says "Sign in with PedsHub SSO". The
password form stays for a site with no provider configured.
Migration r7b8c9d0e1f2 drops invite_codes (three spent rows) and
login_codes (empty). The dump beside it has both.
585 tests, and the contract snapshot is 320 routes — five fewer, all
five named in the diff so the removal is reviewable rather than
discovered later by a client.
Also: "Make a deck" in the signed-in menu and on the landing page, going
to the scribe's My Resources at app.pedshub.com/#resources. Same
sign-in on both sides; the arrow says it leaves.

**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.

Three things landed together; the message names all of them, because a commit
that mentions one is a commit nobody finds the other two in.
**Figures.** Thirty-four JPEG 2000 files — 21 on questions, the rest unattached
in the media library — are WebP now, with `questions.image_path`,
`questions.explanation_image_path` and `media_assets.path` repointed together.
Serving already converted them on the way out, so nothing was broken; this
removes the step and makes what is stored the same thing that is served. The
originals stay: they are the only copy of what came out of the PDF, they cost a
few megabytes between them, and a conversion nobody can undo is not one to run
against a live bank. Paths are found by what the columns say rather than by
listing a bucket, because three tables record them and updating two would be
worse than none.
**The openai SDK is gone.** Ten call sites — one more than the map said, the
Celery article drafter — every one of them a POST with a JSON body, and not one
reading usage, cost, tool calls or logprobs. Every other call to the same proxy
was already plain httpx: embeddings, the ChromaDB embedding function, speech
both ways, model discovery, the vision probe. So this deletes an abstraction
rather than swapping one for another, and leaves one HTTP client instead of
two. `chat()` and `achat()` return the message content; a `ProxyError` carries
the status and the first 500 characters of the body, which is where the proxy
explains itself.
Behaviour is preserved deliberately, including a 600-second fallback timeout
for the four call sites that were running on the SDK's ten-minute default.
Lowering that is a real change and belongs in its own commit.
Proved against the live proxy on both services rather than only against mocks:
a completion, an async completion, a real 400 the vision probe still classifies
as a refusal, 407 models read from the catalogue, and a word read off an image.
**Voice.** A chosen voice is honoured whatever serves it. The prefix check only
accepted a locally served one, so a site adding a hosted voice would offer it
in Settings, save the learner's choice, and then quietly read every question in
the default voice. The list has always come from the database — adding a voice
is a row in Settings → AI models, never a code change.
And the sign-in page stops offering a locked door: `signup-policy` reports
whether registration is open at all, and the Sign up link goes when it is not.
The switch existed and the only way to discover it was to fill the form in.

The tutor is handed the correct answer and the explanation and told it
may reveal them, which is why it has never been offered during a running
exam — require_question_access already refuses that, whatever anyone
sets. What was missing is the other half: an administrator can now
withhold it from study sessions too.
Enforced on the server rather than by hiding a button, because hiding a
button does not stop a request. Reviewing a finished attempt is not
"during" and is unaffected; the answers are shown by then anyway. If
Redis is unreachable the tutor stays on — nothing is revealed that study
mode does not already show, so the permissive direction is the safe one
here.
GET /teach/prompt renders the instructions against a stand-in question,
so an educator answering "why did the tutor say that?" can read them
rather than infer them.
And a handbook at /handbook, for anyone who maintains questions or
articles whatever access they hold. It answers the things that were only
in the code: that a question links to an article three different ways —
a further-reading row, a key point carrying an article and section, and
a [[id|label]] marker in prose keyed by id so renaming does not break it
— what the tutor is told, why a blueprint shapes a paper, why deleting a
question hides it, and why changing the embedding model invalidates
every vector.

The quiz player is a box the height of the window. The question used to
scroll the whole page, which took the session rail and the navigation off
screen exactly when you wanted them; now each column scrolls on its own
and the bar — Exit session, Previous, Next, Review — stays put.
Two site-wide switches, together under Settings → Site policy because
both are the administrator's and both apply to everyone:
* Sharing can be turned off. That stops new links being made; one
already handed to somebody keeps working, since revoking it would
break something a learner has already given away.
* Sign-up can be made invite-only, with single-use codes carrying a
note of who each is for and, afterwards, who it let in. A spent code
is kept rather than deleted — that record is the point of invite-only.
The alphabet has no O/0 or I/1/l, because these get read aloud.
The registration form asks for a code only when the site needs one, via
an unauthenticated policy endpoint — it has to know before there is an
account to ask with. It never says whether a given code is valid before
the account exists, which would make it somewhere to guess them. The
first account is always allowed, or a new install would lock itself out
before an administrator existed to issue a code.
Flags fall back to their defaults when Redis is down, in the safe
direction each way: sharing keeps working, sign-up does not silently
open.
Found on the way: the registration form's three labels named nothing —
no `for`, no wrapping — so a screen reader announced unlabelled boxes.
Backend 261/261, frontend 328/328.
