* POST /api/relay/issue-token — issue a relay registration token (G-005, Wave D Task 1).
|

*
|
||||
* Admin-only. Issues the per-tenant registration token defined in
|
||||
* @coreci/secrets (signRelayToken / issueRelayToken): a signed JWT (HS256) with
|
||||
* claims { tenantId, scope: "relay.register", iat, exp }, 24h lifetime. The
|
||||
* signing key is a platform bootstrap signing key (G-010 tier (a), infra) — NOT
|
||||
* a tenant secret. In dev it comes from RELAY_TOKEN_SIGNING_KEY; in prod it is
|
||||
* KMS-derived. The token is consumed by the Go Relay Agent to authenticate its
|
||||
* first WebSocket connection (Wave D Task 3).
|
||||
*
|
||||
* Returns: { token, expiresAt }.
|
||||
*
|
||||
* The dashboard's /dashboard/relay page (Wave E) embeds this token in the
|
||||
* curl|bash install command so the Platform Lead can copy-paste it onto a

* target host without manual editing (REQ-010).

|

*
|

* Next.js App Router route handlers are HTTP-only (no native WebSocket
|

* upgrade), so for M1 the relay WebSocket server runs as a small standalone
|

* HTTP server alongside Next.js. It binds 0.0.0.0:${CORECI_WS_PORT:-3001} and
|
||||
* upgrades requests to /api/relay/ws.
|
||||
*
|
||||
* Lifecycle per connection:
|
||||
* 1. On upgrade: read Authorization: Bearer <token>, verify the JWT relay
|
||||
* token via @coreci/secrets verifyRelayToken (G-005). If invalid → close
|
||||
* with code 4001 (REQ-012 Edge 12).
|
||||
* 2. On {type:"register"} message: INSERT into targets
|
||||
* (tenant_id, hostname, os_name, os_version, ip_address, agent_version,
|
||||
* last_seen_at=now()) under withTenant + audit append (provision event).
|
||||
* Respond {type:"registered", targetId}.
|
||||
* 3. On {type:"ping"} message: UPDATE targets SET last_seen_at=now() WHERE
|
||||
* id=targetId under withTenant. Respond {type:"pong", ts}.
|
||||
*
|
||||
* Connected agents are tracked in-memory for the dashboard (Wave E consumes
|
||||
* this via `getConnectedAgents()`).
|
||||
*
|

* Run standalone: `tsx ws-server.ts` (next to `next dev`/`next start`).
