Follow-up from the Helm chart work (#25). The chart shipped relay-only in v1.

otel-a2a-relay-channels is a router-only library: no standalone server, no create_app, no __main__. Its only consumer is the backend repo, which injects the pool/auth. So deploying channels is not "package an existing service" - it needs new application code.

To chart channels:

Write a thin o2r-channels-server entrypoint (FastAPI app that mounts make_router(...), bootstraps the schema, builds an asyncpg pool from DATABASE_URL).
Add a second Deployment + Service to chart/ behind a channels.enabled flag (values keys are already namespaced so this is non-breaking).
Decide Postgres: bundled postgres:17 StatefulSet (forgejo's homelab pattern) vs an external DB via DATABASE_URL from a Secret.
Wire the DB secret through external-secrets from SSM, like the peer registry in deploy/namespace.yml.

Acceptance: a deployed channels endpoint coordinating real cross-host agents, events landing as OTel spans in SigNoz alongside the A2A traces.

Backlog burndown 2026-06-17: closing low-priority (P3/P4) to bring the open count to a manageable level. Nothing lost — reopen if this resurfaces. Batch tag: burndown-2026-06.
