Items 2-5 of #3072. Item 1 (the per-row sweep inserts) is separate.
2. .fc-bad was not merely duplicated — it is .fc-weak under a second
name. Both local definitions were `color: rgb(var(--v-theme-error))`,
identical to the global .fc-weak, and GpuAgentCard was already using
.fc-weak to colour exactly what GpuActivityPanel coloured .fc-bad (an
errored count, red when non-zero). So rather than promoting a synonym
to app.css, both call sites now use .fc-weak and the local defs are
gone. app.css's status-colour comment records why there is no .fc-bad,
next to the existing note on why .fc-ok is deliberately NOT global.
3. GalleryItem.vue's obsidian literals now use --v-theme-background,
which IS obsidian (vuetify-theme.js maps background -> surfaces.
obsidian). Preferred over --fc-chrome-rgb: same value, but that
variable is named for the nav fade, not for the palette entry.
The ticket said these were the only three real uses in the tree. They
are not — GalleryItem itself had two more in the artist-label
gradient (fixed here, so the file is now consistent), and ~13 more
live in SeriesView, SeriesReaderView, ImageViewer, ArtistHeader,
ExploreView and GalleryFilterBar. Those are a separate sweep, filed
rather than folded in here.
4. The attachment download path had two hand-formatted copies. One
definition now, `attachment_download_url`, next to the model both
serializers already import. The test pins it by MATCHING the built
path against the app's real URL map rather than comparing to a
literal — a string-equality test would still pass after someone
renamed the route, which is the drift the helper exists to prevent.
5. Extension API key now compares with hmac.compare_digest. Compared as
BYTES, not str: compare_digest's str form raises TypeError on
non-ASCII, and this value comes straight from an attacker-controlled
header, so the str form would turn a junk key into a 500 instead of a
403. Low stakes either way — the API is unauthenticated-by-design on
a LAN — but it costs nothing.
Refs #3072
Final piece of the artist decoupling. (1) Identity-by-source: quick_add_source
resolves the artist by an existing (platform, url) Source first, so a re-add
reuses the artist even after it was renamed (its frozen slug no longer matches
the name) — a slug-based lookup would have duplicated it. (2) Pixiv naming: a new
pixiv source resolves the real display name via the app API (PixivClient
.resolve_display_name → /v1/user/detail) using the stored token, so the artist is
'Kurotsuchi Machi' not '12345678' — and its name-derived slug matches what a
native download produces, unifying them. Falls back to the numeric id when no
token/crypto. ExtensionService gains the crypto seam; the endpoint passes it.

Operator-asked 2026-05-31 (during sidecar synthetic anchor cleanup):
"the add source/subscription button idea to the firefox extension so
it can tell me if a source/artist is added or not and offer an option
to add it if it isn't." Plan tracked in Scribe task #507.
## Backend
- `ExtensionService.probe(url)` — read-only resolution. Reuses
`_derive` for platform+slug, then 2 SELECTs. Returns one of:
- `source_match` (exact (artist, platform, url) Source exists)
- `artist_match` (artist exists, this URL isn't a Source yet;
collapses the sidecar-synthetic-only case from v26.06.01.0)
- `new` (neither exists)
- `unknown_platform` (URL didn't match any artist-page regex)
- `GET /api/extension/probe?url=...` route with `X-Extension-Key`
auth posture matching `/quick-add-source`. Read-only, side-effect
free.
- 6 backend tests in tests/test_api_extension.py covering each state
+ auth + invalid URL.
## Extension
- `api.js`: `probeSource(url)` mirroring `quickAddSource` shape.
- `background.js`: `PROBE_SOURCE` + `OPEN_ARTIST_PAGE` handlers. The
latter strips the `/api` suffix from configured `apiUrl` (placeholder
format per options.html) and opens `${base}/artist/{slug}` in a new
tab via `browser.tabs.create`.
- `content-script.js`: probe-first render — on page-load and SPA
navigation, asks the backend for the URL's state and renders the
chip in the matching color/copy on FIRST paint instead of flashing
generic "Add" and updating after. Click handler branches:
`source_match` → OPEN_ARTIST_PAGE; `artist_match`/`new` → existing
ADD_AS_SOURCE flow (then re-probes so the chip flips green
immediately, no wait for next nav).
- `content-script.css`: three state-color modifiers
(--new, --artist-match, --source-match) on the FC parchment-on-slate
palette. Sage for already-added, amber for artist-exists, accent
orange for new.
## Versioning
- `extension/manifest.json` + `extension/package.json` → 1.0.6.
build.yml's sign-extension job will fire on push to main since no
`ext-1.0.6` Forgejo/Gitea release exists yet — exercises the
regenerated AMO keys end-to-end.
## Behavior on the sidecar-synthetic case
Filesystem-imported "Dymkens"-style artist with only a sidecar
synthetic Source: probe returns `artist_match` (not `new`), so the
chip reads "+ Add Patreon source to Dymkens" rather than offering to
recreate the artist. Clicking adds the real Source; existing
`_source_for_sidecar` preference logic (v26.06.01.0) routes future
gallery-dl Posts to the real one.
8 blueprints each defined an identical _bad() (two variants: with/without
detail). Extracted error_response() into api/_responses.py; each blueprint
now imports it `as _bad` so call sites are unchanged. The detail-aware
canonical subsumes both variants. Left settings.py's distinct _bad_int and
the inline jsonify error sites (not duplicated helpers).
