A Seerr instance behind forward-auth (Authelia, Authentik, Cloudflare
Access) or HTTP Basic failed setup with "No Seerr instance at … (HTTP
200)": the probe followed the proxy's redirect to its login page and
decoded the HTML as "not JSON". A live session that later hit the same
wall took the proxy's 401 as Seerr's, re-authed through the wall, failed,
and unlinked a perfectly good stored session.
Seerr's API never redirects and always answers with JSON, so a 3xx or a
non-JSON 401/403 is the proxy talking. Seerr requests no longer follow
redirects, that shape maps to a SeerrProxyException with a message that
says what to do, the probe reports it in place of "no instance", and the
client neither re-auths nor unlinks on it.

Several pairs of near-identical code paths differ in one load-bearing
line. Each site now carries a comment naming the invariant that forces it
apart, backed by a characterization test so a future deduplication fails
loudly instead of silently changing behaviour.
Pinned: focusable wrapper vs. chip D-pad activation policy, profile
connection cleanup's raw-id vs. ServerId-typed server projections, live TV
tab loaders, video player display matching and playback service wiring,
track selection container ordering, tracker HTTP client status ladder, and
the MediaServerHttpClient shutdown/cancellation contract versus
ManagedHttpClient's closing guard.
