The destination is an OIDC subject id, which the app cannot know — it
belongs to the identity provider — so this runs deliberately, with Petal
stopped and a backup taken, rather than as a startup migration. documents,
tags, vocab_words and images carry user_id directly; versions, suggestions
and tag assignments hang off their parents and follow, which is why it has
to be one transaction with foreign keys off. Sessions for the old identity
are deleted rather than moved: a session is proof someone signed in, and
nobody ever signed in as 'local'.
Dry run by default, VACUUM INTO backup first, and it verifies every row it
expected to move actually moved — and that the source is left owning
nothing — before committing.
The 'is the app stopped?' guard took two attempts. BEGIN EXCLUSIVE, the
obvious check, sails past a running-but-idle Petal because in WAL mode it
only conflicts with another writer, which is precisely the case worth
catching. PRAGMA locking_mode = EXCLUSIVE conflicts with any connection at
all, since it locks the shared-memory index every WAL reader maps.
Sequencing this also turned up a crash waiting to happen: the image
backfill claims unowned files for 'local', which no longer exists after a
migration, and the resulting foreign-key error is fatal inside images.New.
Petal would have crash-looped the first time it started on a migrated
database. It now skips a missing owner, which costs nothing — the
migration moves the image rows itself.

Petal is now an OIDC client in its own right rather than trusting a header
from the proxy. The Phase-0 Resolver seam was the only integration point:
main.go picks the session store when Authentik is configured and the static
local user otherwise, and no handler or query moved for either.
internal/auth gains three pieces. session.go issues an opaque cookie token
and stores only its SHA-256, so a database copy yields nothing usable; the
30-day expiry slides on every request, throttled to one write an hour, and
logout deletes the row rather than just the cookie. oidc.go runs the
authorization-code flow with state, nonce and PKCE, and discovers the
provider lazily and on retry — an Authentik outage should block new logins
without stopping Petal booting or invalidating live sessions. users.go
provisions accounts from the token's claims and gates them on an allowlist
that matches emails as well as subject ids, since a subject is an opaque
uuid that doesn't exist until someone has already logged in once.
Migration 0010 lands sessions, images and users.pair_lang together. The
images table closes the capability-URL hole the Phase-0 audit flagged: a
hash was previously enough to fetch anyone's picture. Rows are keyed
(name, user_id) so one file can have several owners and deduplication
survives; a stranger gets 404 rather than 403, the cache header drops to
private, and files already on disk are claimed at startup or every image
already pasted into a document would 404.
On the frontend a single 401 interceptor feeds a warm bilingual sign-in
overlay, drawn over a still-visible editor because nothing has been taken
away. Behind it is the part that matters: a save that comes back 401
stashes its body to localStorage before anything else and stops the
auto-save loop, and reopening that document after signing in merges the
draft back and saves it. An expired session must not cost writing.
Writing the round-trip test against a stub identity provider turned up a
real bug: the one-shot state/nonce/PKCE cookies were cleared in a defer,
which runs after the redirect has written the response header, so the
clearing Set-Cookie was silently dropped and they lingered for their full
ten minutes.
Also swaps the emoji favicon for a drawn sakura, which renders as Petal's
own rose palette everywhere instead of whatever each platform's font
decides, and doubles as the app tile in Authentik.
Migration 0010 verified against a VACUUM INTO copy of the live millenia
database: counts intact, FTS still matching, the one existing image
claimed.

Two editor features that were in flight alongside the sound work:
- FontSize TipTap extension (rides on textStyle) with Small/Normal/Large/
Title presets in the toolbar; StatusBar + CSS support
- Image handling: internal/images handler, upload route + config, client
API, EditorCore wiring, and md/html/docx export support for images
