- Backend create/can validation paths emit machine-readable error codes
(slug_taken, slug_invalid, content_empty, content_too_large,
expiry_invalid, rate_limited, ...) alongside the human message
- new.html JS maps codes to plain-language guidance with generic fallback
- Result card colored via --ok/--err/--warn left border (result-ok/err/warn)
- docs/API.md error section documents the code field
- Tests assert the code on every validation path
- DELETE now demands the create-time deletion token (Authorization
header: Bearer/Token/bare, or ?token= query param), compared with
the constant-time store.DeletionTokenEqual. 403 otherwise.
- Creator-browser deletes via the /mine button (matching vwr cookie,
#37) remain allowed; other browsers and plain API clients get 403.
- Regression tests: no token, wrong token (header+query), correct
token (header+query), creator-cookie path, token extraction.
- Adapted TestSoftDelete to pass the deletion token.
- docs/API.md delete section updated.
- Based on #58's SoftDelete (bool, error) signature.
- attachments: filesystem-on-PVC recommended, blob interface keeps MinIO
as a later drop-in; size limits via admin setting; sniffed-mime +
nosniff/sandbox serving rules
- storage backend: stay SQLite-only (WAL, modernc); no Postgres/Redis and
no backend abstraction until documented trigger conditions fire
- Three new light [data-preset] blocks alongside midnight (default) and smooth
- --ok/--warn/--err semantic tokens with 4.5:1 contrast per preset
- .toast success/error variants wired in new.html
- ?theme= query param preview hook in layout head (screenshots only)
- Preview screenshots in docs/palette-previews/
Closes#16
