molecule-ai-workspace-templ.../tests/test_executor_plugin_path.py
Hongming Wang f8ee17e2e3 hotfix(adapter): default MOLECULE_A2A_PLATFORM_ENABLED=false 
Staging E2E for PR #32 surfaced a workspace boot failure: the deployed
image's hermes gateway never bound :8645, so adapter.setup()'s
/a2a/health probe got httpx.ConnectError and the workspace went
status=failed at ~498s.

Root cause is image-side install/discovery of the molecule-a2a plugin,
NOT the executor wire shape. Local scripts/e2e_full_chain.py runs
against a venv where I'd already installed the plugin manually — it
didn't catch the deployment-shape divergence.

Flip the default off to restore the legacy /v1/chat/completions
fallback (no session continuity, but works). Plugin path stays
opt-in via MOLECULE_A2A_PLATFORM_ENABLED=true so debugging can
continue per-workspace without rolling the whole image again.

Re-enabling will require:
  - An image-build smoke test that verifies pip show
    hermes-platform-molecule-a2a + hermes config show inside the
    built container (filed separately)
  - Verifying the molecule-a2a config stanza actually lands in
    ~/.hermes/config.yaml inside the running container

Tests updated: 37 pass. Plugin-path tests now opt-in via the helper's
default; default-detection test asserts the new chat_completions
fallback.

"""Tests for the hermes plugin transport in executor.py.
Coverage targets:
- Lifecycle: start() boots reply server; stop() tears it down and
fails any in-flight pending Futures.
- Inbound: execute() POSTs to a stub /a2a/inbound, registers a
Future keyed by message_id, awaits it.
- Outbound: a stub plugin POSTs to our reply server with reply_to
matching the inbound message_id; the awaiting execute() resolves
and emits on the event_queue.
- Auth: shared_secret is sent on outbound POST and required on
inbound reply POST.
- Error paths: empty prompt, hermes-side POST failure, reply timeout,
late/duplicate replies for unknown message_id.
- Fallback: when MOLECULE_A2A_PLATFORM_ENABLED=false the executor
falls through to the chat_completions transport.
