Fixed in commit 4f8b1de. The fallback logic now only applies when a valid agent-task issue exists (selectedIssue is present). If there's no issue, the fallbacks to manifest/PR body/PR author are not used, ensuring that PRs without linked issues will still receive missing_linked_issue errors as expected by the evaluator.

Fixed in commit 4f8b1de. The scheduledContractIdentity function now mirrors the same fallback logic as the collector: it extracts the manifest from PR body, uses legacyRunId to parse PR body for run ID, and falls back to PR author for agent login when the issue body fields are missing. This ensures the identity projection stabilizes across scans.

Fixed in commit 4f8b1de. Added knownAgents set check to the synthetic event creation condition. The synthetic artifact_ready event is now only created when pr.user.login is in both eventAuthors AND knownAgents, preventing non-agent human PRs from bypassing the explicit result-event requirement.

Added four focused workflow-adapter tests in tests/unit/test_agent_completion_gate.py (commit test: add workflow-adapter tests for PR-body fallback and extractRunId parser):
-
test_extract_run_id_duplicate_parser_matches_legacy— extractsextractRunIdand runs it through the same node.js assertion table aslegacyRunId, includingnull/undefinedinputs, confirming the duplicate parser behaves identically. -
test_pr_body_fallback_populates_identity_when_issue_fields_absent— string-asserts the collector step has the correct fallback chain (legacyRunId(prBody)/manifest.agent_login/pr.user.login), then proves via node.js that issue-body fields take priority, fallbacks activate when absent, and the resultingrun_id/loginvalues are structurally valid. -
test_mismatch_errors_require_manifest_match— string-asserts that bothagent_run_id_mismatchandagent_login_mismatchbranches are guarded bymanifestMatch, preventing spurious mismatch errors when no manifest is present. -
test_synthetic_artifact_ready_event_excluded_for_non_agent_author— string-asserts theeventAuthors.has(pr.user.login)guard, then proves via node.js that the event is emitted for a matching agent login, absent for a human or empty login, and that the emitted payload fields (kind,sequence,comment_id,author,head_sha) are valid.

You make this not a test and real code instead

I need clarification on your request. The original review comment asked to "Add focused workflow-adapter tests for the new PR-body fallback" - which I did by adding four test methods to tests/unit/test_agent_completion_gate.py.
Are you asking me to:
- Remove the tests and implement validation logic directly in the workflow file (
.github/workflows/pr-checks.yml)? - Move the test validation logic into production code somewhere (e.g.,
scripts/ci/agent_completion_gate.py)? - Something else?
The tests currently verify:
extractRunIdparser behavior- PR body fallback populating identity when issue fields are absent
- Mismatch errors requiring manifest match
- Synthetic artifact_ready event creation for agent authors only
What would you like converted from test code to "real code"?
…n scheduler - Narrow fallback to only PRs with valid agent-task issues (fixes #3631451991) - Mirror PR body/manifest/author fallback in scheduledContractIdentity (fixes #3631452040) - Restrict synthetic event creation to knownAgents (fixes #3631452069)

Keep this PR draft. Do not approve, merge, or port its bypass. Any legitimate compatibility improvement must retain explicit focused-issue identity, immutable run binding, an independently published exact-head event, and fail-closed mismatch handling, and must be implemented on the canonical #899 branch after explicit repository/security authorization.
