Let members post pictures, and back them up
Phase B. Images on threads and comments, stored in /data/uploads —
inside the volume that already holds board.db, so there is one directory
to back up rather than two and no second mount to remember.

Not in the site repository, which is the distinction that matters: the
content editor uploads by committing, and a private photo committed
there would go through the build pipeline and out onto vienalatina.com.

The type is decided by the first bytes, not the filename. content.py
trusts the extension, which is tolerable where Hugo serves the result;
here we serve it back, so an HTML file called gato.png would be a script
running on our own origin. Five magic-number checks, no new dependency.
The uploaded name is kept only as text to show a person; the name on
disk is generated. Staging is separate from saving so a refused picture
cannot leave a half-made thread behind.

Threads and comments are soft-deleted, so the serving route checks the
parent is still live. Without it, taking a post down leaves its photo
readable by anyone who noted the URL.

And the hole this phase existed to close: backup-board.sh archived
board.db and nothing else, so the first upload would have made the
nightly backup silently incomplete while still reporting success. It now
archives the uploads directory too, verifies the archive, and names the
directory when it is empty rather than passing over it in silence.
Tested by restoring: destroyed the directory, restored from the archive,
compared bytes.

IMAGE_EXTENSIONS moves to uploads.py and content.py imports it, so the
editor and the board cannot drift apart about what counts as a picture.

46 new tests, 176 in total.

Let members get a password of their own
Until now an admin created an account, the password appeared once on screen,
and that was the only copy. Gitea's Forgot password answers "Account recovery
is disabled because no email is set up", because this server has never been
able to send mail. Every route a member had to a password of their own was
closed, which made the members area unusable by anyone not standing next to the
owner.

Now: the admin enters a username and an email, the server creates the Gitea
account with a random password nobody ever sees — the admin included — and the
member is emailed a link to a Viena Latina page where they choose their own.
The same mechanism gives "¿Olvidaste tu contraseña?" that works, replacing
Gitea's dead page. Nobody leaves the site for either, which is possible because
PATCH /admin/users/{username} accepts a password.

A link is enough to take an account, so it is treated as a credential: single
use, short-lived, stored only as a SHA-256, and invalidated when a newer one is
issued so an older email stops working. SHA-256 rather than a password hash
because these are 32 random bytes, not something a person chose — there is no
dictionary to slow down. Recovery answers identically for a known and an
unknown address, or the form becomes a way to enumerate members one address at
a time, and stops after three tries so it cannot be used to mail-bomb somebody
using this server's reputation.

Rejecting a password deliberately does not spend the token. A typo must not
lock somebody out of an account they have never reached.

If the mail fails the admin is shown the link instead. The account exists
either way, so the difference is between a delayed invitation and a person who
simply never gets in.

Found while testing: the rate limit did not work at all. created_at is written
by SQLite as "2026-09-25 15:00:00" and I compared it against Python's
"2026-09-25T15:00:00+00:00"; a space sorts before T, so every row looked older
than any threshold and the limit silently never fired. It is now compared
inside SQLite, where the format and the clock are the same one.

Also drops two tabs from the sign-in page: OpenID, which nobody here will use,
and Register, which contradicted DISABLE_REGISTRATION and invited people to try
something the server then refused.

Verified: 126 checks. Tokens are hashed at rest, work once, expire, die when
reissued, and are refused for a suspended member; a short password and a Gitea
rejection both leave the link usable; recovery is indistinguishable for known
and unknown addresses and stops at three; creating a member emails them and
shows no password; a failed send surfaces the link.

Add a members area: roles and an internal board
Everything on this site so far has been a file built from git. This is the
first component that runs code to answer a request and the first whose data
git does not hold, so the trade is stated in the README and the backup script
is not optional.

Roles are owner, admin and user. The owner is seeded once from BOARD_OWNER and
cannot be seeded again, because otherwise editing a compose file would be a
quieter way to take the top role than asking for it; ownership moves only by
transfer, inside the app. There is exactly one owner and a partial unique index
enforces it, so the invariant holds even when a handler is wrong. The owner is
beyond suspension and demotion by everyone, themselves included. Only the owner
makes admins; admins make users.

Sign-in goes through Gitea as a confidential OAuth client — the opposite of
Decap, which has to be public because it runs in the browser. The rule the
whole thing rests on is that a Gitea account is not a membership: entry needs
an active row in `members`, or every account on the instance is a member,
starting with the translations bot.

Admins can delete any post; nobody can edit anyone else's, admins included.
Taking a post down is visible to its author. Quietly rewriting it is not, and
an admin who could do that could leave a sentence attributed to someone who
never wrote it. The plan said admins could do both; this is the one place the
implementation departs from it.

Markdown renders with raw HTML disabled, which is the entire XSS defence and
the reason there is no sanitiser: the renderer emits only its own tags and
escapes the rest. The CSP carries no 'unsafe-inline', which makes an inline
onsubmit silently inert rather than broken, so the confirmation dialogs live in
a static file and a test fails any template that grows an inline handler.

GDPR is in scope rather than deferred: erasure removes the member row and moves
their authorship to a tombstone so the conversations around them still read,
and any member can download their own writing.

Verified: 63 checks pass, covering the membership gate, every role predicate, a
direct insert of a second owner being refused by the index, atomic ownership
transfer, CSRF, an offsite login redirect, script tags rendering as text, soft
deletes leaving both listings and exports, and the member screens rendering for
each role. Smoke-tested live: headers, both static assets, and the bare
/comunidad redirect that the Caddy matcher has to cover.
