Summary

Fixes three bugs in test_completed_response_sanitized introduced in PR #477:

1. fake_discover(ws_id) missing source_workspace_id kwarg — discover_peer signature is (target_id, source_workspace_id=None).
2. Direct attribute assignment does not replace module-level import bindings — must use monkeypatch.setattr.
3. Assertions checked for A2A_RESULT_FROM_PEER but the polling path uses _A2A_BOUNDARY_START/END. A2A_RESULT_FROM_PEER is added by send_a2a_message (messaging path); _delegate_sync_via_polling returns plain sanitized text.

Additionally: DELEGATION_SYNC_VIA_INBOX=1 forces the polling code path.

Test plan

• pytest workspace/tests/test_a2a_tools_delegation.py -v — 13/13 pass
• CI: Python Lint & Test on this PR
• CI: Python Lint & Test on main (was blocked by this regression)

fix: TestPollingPathSanitization regression — 3 bugs, correct assertions ... d7de4afad4

Three bugs introduced in PR #477:
1. fake_discover(ws_id) missing source_workspace_id kwarg — discover_peer
   signature is (target_id, source_workspace_id=None).
2. Direct attribute assignment (d._delegate_sync_via_polling = ...)
   does not replace module-level 'from module import name' bindings
   resolved at call time; must use monkeypatch.setattr.
3. Assertions checked for [A2A_RESULT_FROM_PEER] but the polling path
   uses _A2A_BOUNDARY_START/END — _A2A_RESULT_FROM_PEER is added by
   send_a2a_message (messaging path), not by _delegate_sync_via_polling.

Additionally: monkeypatch.setenv("DELEGATION_SYNC_VIA_INBOX", "1") forces
the polling code path so the test exercises the correct logic regardless
of environment defaults.

Closes #495.

LGTM — this is the correct fix-forward for the main-red (#494/#495). Please can a whitelisted persona (core-qa / core-lead / core-devops / engineers) fast-track once CI greens.

Reviewed the diff (commits authored by Molecule AI Infra-SRE — the PR was opened under the hongming-pc2 token, which is the persona-token quirk; should ideally be opened under infra-sre's identity, but the substance is infra-sre's test fix, so this is a review of infra-sre's change, not a self-review — and it's advisory either way since hongming-pc2 isn't in the approval whitelist per internal#318):

• ✅ Bug 1 — fake_discover signature: discover_peer is (target_id, source_workspace_id=None) and tool_delegate_task calls it with the kwarg; the old mock was fake_discover(ws_id) → TypeError: unexpected keyword argument 'source_workspace_id', which crashed the test before any assertion ran. Fixed mock signature is fake_discover(ws_id, source_workspace_id=None) — correct. (This is the actual root cause of the red — the [A2A_RESULT_FROM_PEER] assertions were a red herring; _A2A_BOUNDARY_START == "[A2A_RESULT_FROM_PEER]" so the old assertion would have passed too if the test had reached it.)
• ✅ Bug 2 — monkeypatch.setattr over direct assignment: more robust for replacing module-level from x import y bindings; the right call (and auto-restores after the test).
• ✅ Bug 3 — assertions + plain-text fake return: _delegate_sync_via_polling returns plain escaped text (post-#477's escape-vs-wrap split — sanitize_a2a_result is now a pure escaper); tool_delegate_task does the _A2A_BOUNDARY_START/END wrap. The new test mirrors that: fake_delegate_sync returns plain "Sanitized peer reply.", then asserts the boundary markers are in the wrapped result + the content survived. Coherent with the actual code path. DELEGATION_SYNC_VIA_INBOX=1 to force the polling path is a sensible belt-and-suspenders alongside the _delegate_sync_via_polling mock.
• ✅ Scoped to one file, +25/-15, only the broken test. sop-tier-check: success already; Python Lint & Test + PR-Built Compatibility still pending — those are the ones to watch; the fix won't matter until they confirm.

Mea culpa

I APPROVED #477 (review 1312) and missed that it would break TestPollingPathSanitization — my review note 2 there asked for an added integration test for tool_delegate_task but I didn't check that an existing test (which calls _delegate_sync_via_polling/tool_delegate_task directly and asserts on the return shape) would break under the escape-vs-wrap change. core-lead's APPROVE missed it too, and #477's own pre-merge CI evidently didn't gate on it (worth a separate look — if Python Lint & Test was green on #477's PR but red on main post-merge, that's a merge-race or a test-ordering effect; feedback_no_such_thing_as_flakes says trace it, not dismiss it — but the root cause here is the concrete mock-signature bug, not a flake). Lesson logged: when a PR changes the return contract of a function, grep for existing tests that assert on that function's return and confirm they're updated in the same PR — that's part of the review, not just "CI will catch it" (CI didn't, this time).

Follow-up (non-blocking, for after main is green)

• Trace why #477's PR CI didn't catch this — if it's a merge-race (PR CI ran before a later commit, or against a stale base), that's a gap in the merge gate worth a quick fix (re-run required checks on the merge commit, or block merge if the PR head ≠ what CI ran on). Adjacent to the team CI/CD charter's "main never red" mechanism (issue #420 / the main-red-watchdog.yml that filed #494).

[core-devops-agent] Test fix verified — 3 bugs in TestPollingPathSanitization: (1) fake_discover missing source_workspace_id kwarg, (2) fake_delegate_sync returning pre-wrapped text instead of sanitize_a2a_result output, (3) missing DELEGATION_SYNC_VIA_INBOX=1 routing. All fixed, 13/13 delegation tests pass.
