- Around line 220-225: Update mediaAuthModeForReplanV3 so detecting
streamtoken.Header in currentPlan.Stream.Headers sets mode.headerAuth = true
alongside the existing capability and proxy settings. Add a replan test that
removes header authentication from req.ClientFeatures and verifies the
replacement plan uses X-Silo-Stream-Token without a signed token in the media
URL.
In `@internal/api/router.go`:
- Around line 2075-2079: Update the stream route group around
RequireTransportAuth and HandleStream so account-auth fallback requests also
pass viewerAccessMiddleware.RequireViewerAccess, while valid X-Silo-Stream-Token
requests bypass the viewer gate and remain usable without bearer authentication.
Add coverage for both the regular-auth/profile-authorization path and the
stream-token path.

Problem
Related issue: N/A, narrow fix
I traced a separate Apple playback authorization problem that could leave media playing from its buffer while later range requests or an internal reload used an expired bearer and entered a loading or recovery state.
The affected build uses Aether, which snapshots HTTP request headers when it loads an item. Silo's API client can refresh its access token independently, but the already-loaded player continues using the original bearer for subsequent media requests. When that bearer expires, a valid playback session can receive a
401even though its direct-play, remux, or transcode decision is still valid.This is separate from the Apple black-picture autoplay bug. The companion Apple PR fixes the native renderer handoff: Silo-Server/silo-apple#202
Approach
I kept the current tokenless
header_authenticated_media_v1behavior for every unaffected client. For iOS, tvOS, and macOS build 31 clients that advertise the affected capabilities, the playback plan now also returns a signed, session-bound stream capability inX-Silo-Stream-Token.The media URL remains credential-free. The compatibility capability is accepted before bearer fallback only on playback byte-delivery
GETandHEADroutes. It is bound to the playback session, user, profile, file, expiry, and permitted playback recipe. It cannot authorize progress, replan, stop, download, administration, or unrelated API operations.The same mode remains sticky across replans and can reconstruct the existing direct, remux, or transcode recipe after a server runtime restart. Proxy egress is disabled for this affected client path so the private header remains at the Silo origin and is not forwarded to a third-party media origin.
Regular bearer and API-key fallback requests still pass through the normal profile authorization gate. Valid signed stream capabilities use their session-bound profile identity without requiring the stale bearer. The transport rate limiter runs before profile resolution on both paths.
This does not alter route selection or force transcoding. The server still chooses direct play, remux, or transcode from the same playback plan and serves the same media bytes.
Validation

The focused handler and middleware packages also include regressions for an attempted replan feature downgrade, profile rejection on ordinary bearer fallback, capability bypass of the redundant viewer lookup, and the
rate -> viewer -> handlermiddleware order.Review findings
CodeRabbit rated the initial revision high risk and raised two valid issues:
headerAuth, which could allow a future caller outside the existing sticky-feature path to produce a credential-bearing URL or re-enable proxy routing. The current plan's capability header now pins header authentication, with start-to-replan coverage.The first Codex follow-up review then found that my initial viewer-gate composition performed profile resolution before rate limiting. I changed the middleware order and added an explicit ordering test. The second Codex review reported no remaining actionable correctness issues.
Risks
The compatibility path is deliberately limited to the affected Apple platforms and build 31. Other clients retain the existing behavior. The exception can be removed after a released Apple build refreshes player media authorization safely. Device validation is still required with the companion Apple build.
