Problem

Upstream syncs #27 and #28 resolved files wholesale to Silo and dropped Prairie wiring while the Prairie code behind it kept compiling, so nothing failed:

  • Live TV was unreachable. Phone had LiveTvScreen/LiveTvPlayerScreen and DI, but no route, NavHost destination or profile-menu entry. TV had the TvMainRoute.LiveTv* routes but no shell destination or dropdown row.
  • Server-list-first connect with LAN discovery (feat(connect): server-list-first UX with LAN discovery #7): first run went back to manual URL entry on both apps. The TV list lost its Discovered section entirely.
  • Phone Prairie Dusk palette tokens reverted to the Silo OLED values (TV and XML colors survived).
  • Artwork format cascade: ThumbhashImage and startup warmup stopped using ArtworkUrl (the X-Prairie-Image-Formats header survived).
  • App update status rows (feat(settings): show app version and update status on phone and TV #14) vanished from phone and TV settings; the checker was still bound in DI.
  • Labels: "Quick Connect" reverted to "Pair device"/"Pair Device"; "Stats for nerds" reverted to "Playback stats".
  • Rebrand: 21 user-visible "Silo" strings (settings copy, diagnostics, TV setup/sign-up, TV settings header "Silo 1.0.0"), and the README reverted to "Silo Android", including a trademark paragraph that attributed the Silo marks to "Prairie L.L.C." and release links under Silo-Server/prairie-android.

Fix

  • Live TV (phone): Route.LiveTv/Route.LiveTvPlayer (JVM-safe encoding), NavHost destinations (recordings open the library item), LiveTvFeatureStore reset/refresh in MainScreen, and a "Live TV" item in ProfileMenu. The action reaches the menu through LocalLiveTvMenuAction instead of a parameter threaded through Home/Libraries/Calendar/top bar, so the Prairie wiring lives in two files an upstream menu refactor is unlikely to touch.
  • Live TV (TV): shell destinations for the channel list and player, feature-gate refresh, and the "Live TV" profile dropdown row. TvMainRoute.LiveTvPlayer now uses the JVM-safe encoder so it is unit-testable.
  • LAN discovery: with an empty registry both apps start on the server list, with no Back, and scan once. The TV list gets Scan network, scan status/errors and Discovered rows again, on top of upstream's current focus handling.
  • Restored the phone Dusk tokens, the artwork cascade (skipped when a cacheKey marks a signed avatar URL, since a rewritten path would only 403), self-contained update-status rows (checker from Koin, no ViewModel plumbing), the two labels, the Prairie strings and the README.
  • Regression guard: scripts/check-prairie-invariants.sh + scripts/prairie-invariants.txt (75 anchors, same tab-separated format as prairie-server; supports directory paths and absent for forbidden patterns such as user-visible "…Silo…" literals) and a Prairie invariants CI job. Run against current main, 35 anchors fail, which is exactly the loss list above. docs/upstream-sync.md documents the sync procedure; AGENTS.md notes the Live TV exposure.

Intentionally not restored: the TV X-Prairie-Platform value androidtv from 63055d1. Upstream now keys client family and diagnostics on android-tv, so reverting it would break TV settings scoping.

Validation

  • ./scripts/check-prairie-invariants.sh: all 75 hold on this branch; 35 fail on origin/main.
  • New unit tests: LiveTvRouteTest (phone) and TvLiveTvRouteTest (TV) cover route strings, argument encoding and route patterns.
  • Gradle build/tests/lint run in CI only (host memory limits); see checks.

Risks / follow-up

  • Needs on-device checks: the Live TV menu entry on a server with channels, the first-run server list on phone and TV, and the Dusk palette on phone screens that upstream built against OLED black.
  • android-shared/src/androidMain/res/raw/startup_splash_lottie.json came from upstream's "Rebuild the startup splash from the vector brand assets" (Rebuild the startup splash from the vector brand assets Silo-Server/silo-android#229), and its metadata still names Silo. The animation may show the Silo mark and needs a Prairie brand-asset pass. I did not regenerate it here.
  • Icons on text-only buttons (1a3701d) are partly gone where upstream rewrote those screens. This is cosmetic and was not restored.

…syncs

Upstream syncs #27 and #28 resolved files wholesale to Silo and dropped
Prairie wiring while the code behind it kept compiling:

- Live TV: phone and TV screens existed but no route, destination or
  profile-menu entry reached them. Restore the phone routes, NavHost
  destinations and ProfileMenu item (provided via LocalLiveTvMenuAction so
  future menu refactors cannot drop it), and the TV shell destinations and
  profile dropdown row. Feature-gated by LiveTvFeatureStore as before.
- LAN discovery: first run lands on the server list again (phone and TV),
  scans once, and the TV list shows Discovered servers and Scan network.
- Phone Prairie Dusk palette tokens, the AVIF/WebP/PNG artwork cascade in
  ThumbhashImage and startup warmup, the app update status rows (phone and
  TV), the Quick Connect and Stats for nerds labels.
- User-visible "Silo" strings in app code and the README (including a
  trademark paragraph that attributed the Silo marks to the wrong owner).

Add scripts/check-prairie-invariants.sh + scripts/prairie-invariants.txt
and a "Prairie invariants" CI job so the next sync that drops any of this
fails CI, plus docs/upstream-sync.md. Route unit tests cover the Live TV
route contract on both apps.

Merge Risk: 🟡 Moderate · up to 19074

Fix the TV first-run back-stack behavior and the D-pad Up handling on the Live TV player before merging. The invariant checker can also report success after a failed search, which is a smaller issue that should be fixed too.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 19074

Credential isolation remains in place in the inspected flows. However, newly reachable Live TV playback does not coordinate pending session creation with stop and navigation teardown. Interrupted playback may leave shared server resources without a confirmed release; server-side expiry and resource limits are not established.

Retained concerns

  • Medium · reliability · inferred: The restored player destinations expose a session lifecycle without pending-start fencing or assured release ownership. stop reads only an already-published session ID, so stopping during creation does not invalidate the pending operation. For an established session, release is launched asynchronously in the view-model scope that navigation teardown can cancel. Shared tuner or streaming resources may therefore outlive the client screen; server expiry and allocation bounds remain unknown. The controller predates this PR, but the restored callers expand its effective exposure.
Security review details

Security Blast Radius

  • inferred — The newly reachable playback lifecycle can affect session resources on the selected media server, potentially shared with other viewers. LAN discovery also exposes server names and candidate endpoints to a local hostile responder, but selection remains a user action. Cross-server credential inheritance was not supported by the inspected token-scoping controls.

Security Findings and Attack Paths

  • inferred — Leaving playback during session creation can prevent the client from learning the allocated session ID, while release after stop can race view-model cancellation. This is a resource-cleanup uncertainty exposed by restored navigation. Persistent exhaustion, privilege escalation, and unauthorized session access were not verified.

Trust Boundaries and Controls

  • observed — Health and candidate setup probes explicitly omit authentication. The shared request interceptor removes credentials on skipped-auth and cross-origin requests, and checks cleartext approval even for skipped-auth POSTs that carry login or setup credentials in their bodies. Thus discovery selection does not itself demonstrate credential disclosure.
  • observed — Discovery accepts successful health responses reporting ok, healthy, or up. The selected advertised name is persisted, while the discovery serverId is not used to authenticate the selected registry identity. The underlying discovery behavior predates this PR; restored TV rows and first-run routing increase its visibility. Production authenticity expectations remain unavailable.

Resilience and Maintainability Implications

  • observed — The player invokes stop on Back and disposal, releases the local media player on disposal, and releases a returned session when its stream URL is blank. These are meaningful cleanup controls, but stop launches server release asynchronously and onCleared does not provide an independent release path.

Hardening Proposals

  • proposed — Bind session creation and release to an explicit owner and generation. Invalidate pending starts on stop, release any late allocation under its originating identity, and provide bounded cleanup that survives screen teardown. Establish server-side expiry and allocation limits for requests whose responses are lost.

- Line 28: Update the grep count logic used by the invariant checks to treat
grep status 1 as zero matches while propagating other errors instead of masking
them with `|| true`. Ensure the callers on lines 28 and 30, including the call
near line 47, exit or record a failed invariant if counting fails.

…-pad Up

- With the server list as the first-run root, Add Server pushed setup on
  top of it and the auth chain's popUpTo(ServerSetup) left the list under
  Home/Main, so Back returned to the connect screen. Hand the root to
  setup on first run (phone and TV).
- The TV shell's preview handler consumed D-pad Up on every route; skip
  it on the Live TV player so the PlayerView controls receive it.
- check-prairie-invariants.sh: propagate grep errors (status > 1) instead
  of treating them as zero matches, so an invalid regex on an "absent"
  invariant cannot pass.
