Four model surfaces parsed, coerced, and re-serialized data with zero readers: PlayQueueResponse's selectedItemIndex/offset/sourceURI/version (version stays as a parse-time validity gate), PlexUserProfile's seven non-track-selection account fields, MediaSubscriptionCreateRequest's hints/params/providers, and the whole CatalogPlayState pipeline (parsed by the Plex catalog source, merged and round-tripped on every CatalogItem, read by nobody).
Around July 3 plex.tv started returning the profile language-list fields
(defaultAudioLanguages, defaultSubtitleLanguages, mediaReviewsLanguages)
as comma-separated strings instead of arrays. The generated cast threw on
the successful 201 /switch response, dropping the freshly minted Home
user token: every rebind failed, the binder retried a /switch mint every
1-2s, and the app sat permanently in offline mode even after re-signing
in. Accounts without language prefs set were unaffected, which is why
the breakage looked sporadic.
Parse the language lists with a CSV-aware coercion, and make
UserSwitchResponse.fromJson strict only about authToken: decorative
fields now coerce tolerantly and a broken profile blob falls back to
defaults, so account-API drift can never brick token minting again.
