feat(discovery): identify servers across addresses for TV handoff - #1271
Merged
Merged
Conversation
A phone and a TV can reach one deployment through different addresses (public URL, LAN, overlay origin from a network access provider), but clients derive server identity from the URL and companion pairing hands the TV the phone's address whether or not the TV can reach it. Add a stable per-deployment server ID (internal/serveridentity, stored in server_settings, seeded with insert-if-absent so API processes converge) and two additive /api/v2 operations: the public getServerIdentity, linked from system/info as links.identity, and the authenticated getServerConnections capability document listing the public URL and each installed provider with its API-host state and overlay origin when connected. Node addresses, enrollment URLs and admin status stay private. The ID is self-asserted and authorizes nothing; device-login approval remains the proof that two addresses share one backend.

- Around line 35473-35475: The source contract must model ServerAccessPath and
ServerEndpoint as mutually exclusive tagged-union variants instead of requiring
only kind. Update their Schema methods using the existing OneOf pattern: require
provider for provider paths, url for public endpoints, and provider plus state
for provider endpoints while rejecting fields belonging to the other variant;
keep endpoint url optional for connected providers, then regenerate the OpenAPI
artifact.
In `@docs/architecture/server-identity.md`:
- Around line 25-28: Clarify the documented semantics of server_id so a cloned
database intentionally represents the same deployment, including that clients
may group the clone with the original and discover its addresses. Update the
surrounding server identity explanation to explicitly state this behavior and
retain the existing authorization caveat; do not introduce clone initialization
unless the implementation supports minting a new ID.

Review feedback on #1271: ServerEndpoint and ServerAccessPath required only kind, so a validator accepted a public endpoint without a url or a provider endpoint without its slug and state. Both are now OneOf unions of per-kind variants, following the ProgressSyncResult pattern. The wire shape is unchanged. The identity doc now states what a database clone means and how an operator separates one. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

…outing (#342) Consume the server identity contract (Silo-Server/silo-server#1271) so a phone on a network-plugin address and a TV on the public address recognize one deployment, and fix a cluster of SiloRemote playback bugs found while testing it. Identity (#341): - Registry entries learn a verified deployment identity; matching accepts equal identities alongside the existing origin rule. Registry keys and credential slots are unchanged. - SiloControl hello, TXT record, and handoff offer carry the identity and the deployment's other addresses. The TV probes candidates and uses the first that answers with the expected identity; a different identity is refused. - Companion pairing pushes identity and endpoints. The TV probes the pushed address, and on failure shows provider help with an explicit public fallback. Frames echo the pushed URL; the TV saves the address that worked. Failures now carry typed codes. SiloRemote routing and playback: - One "engaged" predicate drives the mode button, mini-bar, and routing. - Every streaming play goes through the router, so an engaged TV (including mid-reconnect) always takes it; offline plays prompt. - Playing a different title asks before replacing what the TV is showing. - The phone accepts a reused handoff_ready without a challenge, and the TV hands the identity generation to a replacing player. - The remote scrubber commits on value settle, so a missed end-of-edit callback no longer pins the slider and swallows later drags. - Connecting to a server from the Change Server flow pops the stack.

Problem
Related issue: #1268
A phone and a TV can reach the same deployment through different addresses: the configured public URL, a LAN address, or the overlay origin a network access provider exposes (#1096). The Apple and Android clients derive a server's identity from its URL, so the two addresses look like two servers and the remote-only picker hides the TV. Companion pairing sends the phone's saved URL to the TV, which may be unreachable from there. The server offered nothing a client could use to recognize one deployment across addresses or to find an address the TV can reach.
Approach
Two additive
/api/v2operations and one new package.internal/serveridentitymints one random UUID per deployment on first read and stores it inserver_settingsasserver.identity_id. Seeding uses insert-if-absent, so concurrent API processes converge on one value. Each process caches it. The row is plaintext on purpose: aSECRET_KEYrotation must not change who a server is. It survives restarts, hostname and URL changes, and database restores. A cloned database carries the same ID to the clone; that is accepted because the ID authorizes nothing, and no regenerate operation is added.GET /api/v2/system/identityis public and returnsserver_id. The system info document links to it aslinks.identity, so the build-wide discovery document stays fixed and the per-deployment value sits next to it.GET /api/v2/system/connectionsis authenticated (account, no profile) and is the capability document for the feature. It returns the server ID, the access path the request arrived on (defaultorproviderwith the slug, read from the ingress middleware), and the endpoints: the public URL askind: publicwhen configured, then each installed provider with display name and API-host state, carrying aurlonly while connected. Node backend addresses, enrollment URLs and admin error text are not included. A missing public URL is a missing endpoint; nothing is derived from the requestHost.The ID is deliberately unsigned. The proof that two addresses share one backend remains device-login approval: the TV opens a pairing request at the candidate address, the phone approves it through its own connection, and tokens are issued only if both landed in the same store. A matching ID or display name authorizes nothing by itself.
docs/architecture/server-identity.mdrecords this and the client flow.The diagnostics installation ID and the Jellyfin-compat server ID were not reused. The first keys upload manifests and import receipts; the second is a configurable compat setting. jellycompat is unchanged.
Client follow-ups: Silo-Server/silo-apple#341 and Silo-Server/silo-android#352.
Validation
internal/serveridentity(mint once, 32 concurrent processes converge on one write, non-conditional store fallback, cached reads) andinternal/apiv2(both handlers, public access,links.identity, ETag revalidation, provider state coercion, disconnected provider loses its URL, absent and malformed public URL, provider access path, dependency and read failures). All pass.golangci-lint --new-from-revon the touched packages reports no issues.TestAdminResourceCapabilitiesAndScopeininternal/apiv2fails on this branch and identically on a pristine checkout ofmain; it is unrelated.Risks
Additive contract only; no migration and no schema change. The identity is a new public field, but a UUID with no key material discloses nothing about the deployment. The connections document is authenticated and exposes only the public URL and provider origins on the API host, both of which a signed-in client could already observe by being connected. A cloned database shares its ID with the source until a regenerate action exists.
