Promotes Bifrost (@maximhq/bifrost — Go AI-gateway) from an env-only relay
sidecar to a first-class embedded/supervised service, matching the existing
cliproxy/9router model. Implements item #2 of #5670; the broader RouterBackend
contract (items #1, #3-#5) stays out of scope.
- Installer (npm-style, ninerouter model): install/update/getInstalledVersion/
getLatestVersion (1h cache)/resolveSpawnArgs (Go single-dash flags, pinned
BIFROST_TRANSPORT_VERSION), needsApiKey=false
- Bootstrap SERVICES entry (healthPath /v1/models) + spawn-args factory branch
- Migration 113 seeds the version_manager row (not_installed, port 8080,
auto_update=1, provider_expose=1)
- 7 lifecycle API routes under /api/services/bifrost/ (verbatim from cliproxy,
errors sanitized) — loopback-only via existing LOCAL_ONLY_API_PREFIXES
- Shared [name]/logs branch for bifrost
- Dashboard tab + registration in the services page shell
- Relay auto-wiring: getBifrostRoutingConfig defaults BIFROST_BASE_URL to the
supervised port when the instance is running; explicit env still wins; the
env-only relay path (/v1/relay/.../bifrost) stays unchanged (compat layer)
- Docs (EMBEDDED-SERVICES, openapi) + unit tests (installer/route-guard/routing,
19 tests) + RUN_SERVICES_INT-gated integration lifecycle
Note: the actual Go-binary install/start/health path requires a documented VPS
live-test before merge (Hard Rule #18 / spec section 7); the gated integration
harness is the vehicle for that run.
