# 017 — HMMM Adapter Wiring and Tests in BZZZ

- Area: `pkg/hmmm_adapter/`, `pubsub/`, coordinator
- Priority: Medium

## Background
We need a minimal adapter that lets HMMM publish raw JSON to per‑issue topics using BZZZ pub/sub, plus tests. This enables per‑issue rooms without imposing BZZZ envelopes.

## Scope / Deliverables
- Adapter:
  - Implement a small bridge with hooks to `JoinDynamicTopic(topic)` and a `PublishRaw(topic, payload)` helper.
  - Path: `pkg/hmmm_adapter/adapter_stub.go` (scaffold added).
- PubSub:
  - Add a `PublishRaw(topic, payload []byte) error` helper that publishes bytes without BZZZ `Message` envelope.
  - Ensure `JoinDynamicTopic` idempotently joins per‑issue topics.
- Tests:
  - Adapter unit tests (scaffold added) verifying join and publish calls.
  - Optional pubsub integration test with a loopback topic.
- Integration:
  - Initialize the adapter + HMMM Router in main and/or coordinator; start using `router.Publish` for HMMM messages.

## Acceptance Criteria / Tests
- `go test ./...` passes, including adapter tests.
- Per‑issue publish path works in a development run (seed message appears on `bzzz/meta/issue/<id>`).

## Notes
- Next issues: persistence/indexing (HMMM 004), SLURP wiring (HMMM 005).
