fix: restore Prairie features dropped by upstream syncs and add an invariant guard - #35
Merged

Conversation
…t guard Upstream syncs left several Prairie features compiled but unreachable or unwired. Restore them: - First-run connect list (Saved + LAN discovery) is the needsServerSetup root again; manual entry and tvOS phone pairing stay behind "Add manually". - iOS Settings: Quick Connect row near the top and About update status, latest version, changelog and release links. macOS gets both too. - X-Prairie-Image-Formats on API, download and pairing requests again. - iOS scrub bubble shows server trickplay tiles (then Aether's frame, then the chapter still), matching the tvOS scrubber. - Hosted diagnostics point at diagnostics.prairieserver.org (Android parity) instead of Silo's collector. - Live TV player heartbeats its tuner session every 30 s so a paused stream is not reclaimed after the server's 90 s idle TTL. Add scripts/prairie-invariants.txt + check-prairie-invariants.sh, a "Prairie invariants" workflow on every PR, and docs/upstream-sync.md. On current main the guard reports 11 failures; on this branch all 47 hold. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Verify the collector is available before release.
The default URL does not resolve. Confirm that diagnostics.prairieserver.org resolves and that its public capabilities endpoint returns the expected collector identity before release.

Keep fallback artwork visible when the trickplay image is unavailable.
TrickplayTileImage renders only a translucent placeholder while LazyImage has no decoded image. Because MobilePlayerControls selects this view whenever scrubTrickplayTile metadata exists, it hides an available scrubPreviewImage and chapter thumbnail during loading and after a failed image request. This removes scrub artwork but does not prevent seeking or playback.
Show the fallback artwork until the trickplay image loads successfully, and keep it available if loading fails. Preserve the trickplay tile as the preferred artwork after it loads.

Problem
Upstream Silo syncs left several Prairie features compiled but unreachable or unwired. The Prairie types survived, so nothing failed to build, but no screen called them. I audited every merged Prairie PR (#1–#34) by checking that each PR's added lines still exist anywhere in the tree (accounting for renames such as
ArtworkURL→ArtworkVariantURLand Continuum → Prairie), then checked each feature's call sites.ConnectServerListViewhad no caller;needsServerSetupshowedServerSetupViewdirectlyQuickConnectViewhad no caller after the iOS settings restyle (IOSSettingsOverview)X-Prairie-Image-Formatsheader (#23)LanDiscoverysent it; HTTPClient, downloads and pairing lost ithttps://diagnostics.siloserver.org; Android usesdiagnostics.prairieserver.orgPOST …/sessions/{id}/heartbeat; the Apple player never sent heartbeats, so a paused stream lost its tunerFix

Manual entry and tvOS phone pairing stay behind Add manually.ImageFormats.apply(to:)stamps the header in HTTPClient (both auth paths),DownloadSessionDelegateandPairingDeviceAPI.diagnostics.prairieserver.org. The collector IDsilo-public-diagnostics-v1is unchanged, matching Android.LiveTVPlayerViewsends a heartbeat every 30 s while it is open. The/api/v1allowlist count forPrairieAPI+LiveTV.swiftgoes from 10 to 11.Sync-loss guard
