Summary

  • Unified PLATFORM_URL fallback from http://platform:8080 to http://host.docker.internal:8080 across 13 modules
  • All docstrings updated to match

Rationale

The provisioner already injects PLATFORM_URL into every container (from cfg.PlatformURL, which defaults to host.docker.internal). The Python runtime was inconsistent — 9 module-level constants and 1 local variable still defaulted to http://platform:8080 (the Docker Compose service name), which is unreachable outside the compose network.

Fixes backlog item 14 (PLAN.md) — MCP client / platform API calls from workspaces now use the correct host-gateway default.

Test plan

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

Cherry-pick PR #6 review fixes from closed molecule-ai-workspace-runtime PR:
- serverInfo.name: "a2a-delegation" → "molecule" (matches registration name)
- conn_id: full UUID instead of [:8] slice to avoid collision across connections
- heartbeat: emit "data: null" instead of "data: {}" (correct SSE null value)
- Remove dead _sse_broadcaster (unused, superseded by queue.put in _run_http_server)

Unified the fallback default for PLATFORM_URL from `http://platform:8080`
(Docker Compose service name) to `http://host.docker.internal:8080`
across all 13 modules that declare it. This matches:
- The provisioner's default (buildContainerEnv injects PLATFORM_URL
  from cfg.PlatformURL, which defaults to host.docker.internal on the
  platform side — main.go:platformURL)
- The molecule-git-token-helper.sh script (already uses host.docker.internal)
- The MCP client (MOLECULE_URL injected by provisioner)

The provisioner always sets PLATFORM_URL in production containers, so
this is a development/Docker-only improvement: without this change,
a workspace started outside the Docker Compose network (e.g. via
`docker run` with `--network host`) would fail platform API calls
with "Connection refused" because `platform:8080` resolves nowhere.

13 modules updated: a2a_cli, a2a_client, a2a_mcp_server, adapters/base,
builtin_tools/a2a_tools, builtin_tools/approval, builtin_tools/delegation,
builtin_tools/hitl, builtin_tools/memory, consolidation, coordinator,
main, molecule_ai_status. All docstrings updated to match.

Closing — wrong repo per mirror-guard policy.

The PR body is good (unifying PLATFORM_URL fallback to host.docker.internal:8080 is the right fix; resolves PLAN.md backlog item 14), but molecule-ai-workspace-runtime is a publish artifact of molecule-ai/molecule-core. The 13 molecule_runtime/*.py files in this diff are regenerated here by the publish-runtime workflow from workspace/molecule_runtime/*.py in molecule-core.

ci / mirror-guard is correctly blocking — the bypass landed in #8 only covers .gitea/workflows/* and .github/workflows/* paths, not runtime source.

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

  • branch off molecule-core's staging
  • edit workspace/molecule_runtime/*.py (same 13 files)
  • PR into molecule-core; once that merges, the publish-runtime workflow will regenerate this mirror automatically

No work lost — your diff is exactly the same content, just on a different base. Pinging Infra-Runtime-BE on the side.

Closing as wontfix (architectural redirect, not a code rejection).
