Summary

Cherry-pick of PR #6 review fixes from closed molecule-ai-workspace-runtime PR:

  1. serverInfo.name — stdio returns "molecule"; HTTP transport returned "a2a-delegation". Both now use "molecule" for consistency across transport modes.

  2. Full UUID for connection IDs — conn_id = str(uuid.uuid4())[:8] truncates to 8 chars, increasing collision risk across concurrent SSE connections. Use the full UUID instead.

  3. Fix heartbeat data format — data: {} emits a Python dict repr, not valid JSON. Change to data: null (SSE event data field) which is correct JSON and semantically meaningful (no payload, just keepalive).

  4. Remove dead code — _sse_broadcaster was defined but never called. The POST handler pushes directly via the lock; this function only confused the reader.

Test plan

  • pytest -v — 129/129 pass
  • Gitea CI — pending (CI currently down per memory context)

Four corrections to PR #5 (fix/hermes-mcp-platform-tools):

1. **Remove dead code** — `_sse_broadcaster` was defined but never
   called. The POST handler pushes directly via the lock; this function
   only confused the reader.

2. **Full UUID for connection IDs** — `conn_id = str(uuid.uuid4())[:8]`
   truncates to 8 chars, increasing collision risk across concurrent
   connections. Use the full UUID instead; the logger/telemetry can
   still truncate if needed.

3. **Fix heartbeat data format** — `data: {}` emits a Python dict repr,
   not valid JSON. Change to `data: null` (SSE event data field) which is
   correct JSON and semantically meaningful (no payload, just keepalive).

4. **Unify serverInfo.name** — HTTP transport returned
   `"a2a-delegation"` while stdio returns `"molecule"`. Both now use
   `"molecule"` for consistency across transport modes.

Closing — wrong repo per mirror-guard policy.

Same story as #9: molecule_runtime/a2a_mcp_server.py is regenerated here from workspace/molecule_runtime/a2a_mcp_server.py in molecule-core. The 4 review fixes (serverInfo.name, full UUID, heartbeat JSON, dead-code removal) are correct fixes; they just need to go through molecule-core.

Please re-file against molecule-ai/molecule-core:

  • branch off molecule-core's staging
  • edit workspace/molecule_runtime/a2a_mcp_server.py
  • PR into molecule-core; publish-runtime workflow republishes here automatically

Closing as wontfix (architectural redirect, not a code rejection). Infra-Runtime-BE pinged.
