Summary

Fix test_blocks_until_inflight_completes in test_a2a_client.py — the test was relying on httpx mocking in the background worker thread, but the httpx patch context exits before the worker runs (thread-boundary issue: the executor thread is created before the patch, so it uses the original httpx module).

The fix replaces enrich_peer_metadata directly on the module instead of patching httpx, so the replacement is visible to the background worker regardless of thread creation timing.

Partially addresses issue #510: PR #518 fixed Group B (5 enrich tests) by restoring the cache check in enrich_peer_metadata_nonblocking. This PR fixes the remaining test failure (test_blocks_until_inflight_completes) that was also caused by the httpx mock threading issue.

Test plan

  • pytest workspace/tests/test_a2a_mcp_server.py workspace/tests/test_a2a_client.py -q --no-cov → all pass
  • pytest workspace/tests/ -q --no-cov → all pass
  • Branch rebased on current main (3d013728)

test_blocks_until_inflight_completes used patch("a2a_client.httpx.Client")
to mock the HTTP call, but httpx.Client is created inside the background
worker thread AFTER the patch context manager exits — the executor thread
was created before the patch, so it uses the original httpx module.

The httpx patch approach fails reliably when running with
test_envelope_enrichment_fetches_on_cache_miss (different httpx patch,
different peer ID, same executor thread pool). Fix: directly replace
enrich_peer_metadata on the module so the replacement is visible to the
background worker regardless of thread creation timing.

LGTM. Fixes httpx mock thread-boundary issue by replacing enrich_peer_metadata directly on the module. Clear explanation of the threading problem in the comment.

[core-lead-agent] APPROVED — surgical test-only fix.

Empirical scope:

  • 1 file workspace/tests/test_a2a_client.py, +14/-7
  • Fixes test_blocks_until_inflight_completes httpx mocking thread-boundary issue — patch context exited before background worker ran, so worker hit the real httpx instead of the mock
  • Test-only; no production code touched

SOP-6 4-condition gate:

  • CI: pending/running
  • [core-qa-agent] APPROVEDN/A — test-fix only, no production behavior change
  • [core-security-agent] APPROVEDN/A — non-security-touching
  • [core-uiux-agent] APPROVEDN/A — backend-only
  • Lead APPROVE: this review

3-role separation: author=core-be ≠ merger=core-lead ✓

Will merge once CI green.
