The dev Vite proxy rewrites the request Host to 127.0.0.1:8000, so the
backend's absolute signed file URLs pointed at a different origin than the
SPA (localhost:5173). Images tolerated it, but the auth'd fetch that reads
the staging blob for IQDB was blocked ('Cross-Origin Request Blocked') and
every similarity check died before reaching e621.
apiUrl() now keeps API-built absolute URLs on the page's origin whenever the
SPA is in same-origin mode (dev proxy, deploy nginx) and leaves them
absolute when an explicit backend URL is configured. All consumers use it:
staging previews and the bulk modal, library cards, optimizer (range sniff +
worker), IQDB card, delete page, similar page.
e621 identification now follows the documented 'App/version (developer)'
form: server-side requests send 'J621/<hash> (JakeBreath)' and the browser
_client gets the same string, with the hash baked into the frontend image
(GIT_HASH build arg; guarded at runtime so the dev server still works).
IQDB stalls: requests now time out after 20s (a hung fetch used to block the
serialized e621 queue forever), and all checks run through one serial drain
so repeated 'Check similarity' clicks can no longer start overlapping runs
that re-download the same staging blobs. Auth/rate-limit/timeout/network
failures stop the queue with the reason and a retry button instead of
grinding through the rest.
Verified live: staged file URL is same-origin through the proxy and fetches
200 through it.
DESIGN.md asks for metadata panels to slide up from the bottom under
768px. A BottomSheet component provides the trigger pill and the sheet
(backdrop blur, scroll lock, Escape to close) and ResponsivePanel swaps
between it and the existing desktop <aside>, so panel content is mounted
once either way.
Applied to the Library/Online/Similar detail asides and to long pool
descriptions. Upload needed nothing: its metadata editor is already a
full-screen modal that stacks cleanly on small screens.
Inline banners and per-row status text reported action results all over
the app; they are replaced by a small toast stack (bottom-right, Level 3
floating well styling) that only speaks for actions: successes fade,
errors stay until dismissed, and form-field validation stays inline.
Destructive actions no longer use bespoke inline confirm steps (the
library detail's Confirm delete button) or fire immediately (duplicate
copies/items, delete page selections, temp cleanup, upload discard, job
cancellation): they all go through one promise-based confirm dialog
(confirmAction) with a danger variant, Escape/backdrop to cancel.
- /similar (nav: Similar): drop a file to get the exact MD5 match, the
perceptual matches against the library, and e621 IQDB candidates
(auto-run for images when credentials are configured). Read-only —
nothing enters the library.
- SimilarityCheck model + /api/similarity/ (create/list/retrieve/delete)
with signed preview URLs and an expires_at timestamp.
- Temp files are wiped on startup (AppConfig.ready, file-only so no
database access during initialization), lazily past
SIMILARITY_TTL_MINUTES (default 30, env-overridable), on delete, and
by manage.py cleanup_similarity.
- uploadFile() takes a target path; .env.example documents the TTL.
