The permission model being built reads the HTTP method to decide whether a
non-owner may make a call: safe methods are reads, everything else is a write.
That only works if the method tells the truth. These five read something and
returned it while announcing themselves as writes, so a member would have been
denied a read they are entitled to because of a habit in how the route was
declared.
/api/file-browser/video-info POST {url} -> GET ?url=
/api/file-browser/video-playlist POST {url} -> GET ?url=
/api/server-settings/ocr/models POST {url} -> GET ?url=
/api/transmission/_officer/port-test POST -> GET
/api/jellyfin/_config/:id/test POST|GET -> GET only
The last one already answered to both, which is worse than either: a method that
means nothing cannot be the thing authorisation reads.
Deliberately stops at five. A sweep of all 100 mutating routes found many more
reads wearing POST, and they are staying, for two reasons that are not going
away: some need a request body GET cannot carry (/stt takes multipart audio;
/tts, /ocr, /transcribe take payloads), and some carry a credential, where a
query string is the wrong place — access logs, shell history and Referer headers
all capture those, request bodies do not (/tts/voices takes an apiKey, the four
/test endpoints take connection secrets, /local-providers/probe takes auth).
So the method alone can never carry the permission model, and the registry will
need an explicit per-route classification regardless. Converting these five is
worth it because it is free; converting the rest would be a breaking change
across 117 mobile call sites that buys nothing.
Web callers updated in the same commit; the sidecar contract comments now match.
Mobile has exactly one caller to change — transmissionPortTest in
packages/core/src/services/transmission.ts — and no shim was added, because an
endpoint answering to both methods is the problem this commit exists to fix.
docs/api-method-changes-2026-08-06.md is the handoff for the mobile team: what
changed, the one line to edit, what deliberately did NOT change and why, and how
to verify.
