Pull request overview
This PR aligns tooling and verifier behavior with the post-merge reality surfaced in #2858 by (a) making the branch-protection enforcement tool’s defaults reflect the intentionally narrower required-context policy, and (b) tightening PR verifier schema-repair handling so “textless” repair responses don’t get misreported as real repair attempts.
Changes:
- Update
tools/enforce_gate_branch_protection.pyto (1) default required contexts tosummary(notGate / gate) and (2) ensure the snapshot artifact accurately recordsdesired.strictbased on--allow-non-strict. - Add coverage in
tests/tools/test_enforce_gate_branch_protection.pyto confirm snapshot artifacts track the non-strict policy correctly. - Improve
scripts/langchain/pr_verifier.pyschema-repair handling by extracting text-only payloads and treating empty / metadata-only repair replies as “no repair,” with corresponding tests.

| tools/enforce_gate_branch_protection.py | Adjusts default required-context guidance and fixes snapshot “desired strict” reporting to match --allow-non-strict. |
| tests/tools/test_enforce_gate_branch_protection.py | Adds regression coverage ensuring snapshot artifacts don’t claim strict enforcement when non-strict is allowed. |
| scripts/langchain/pr_verifier.py | Introduces _text_from_response_content and makes schema repair reject empty/metadata-only “repairs.” |
| tests/scripts/test_pr_verifier_structured_output.py | Adds tests ensuring textless repair outputs are treated as no repair and don’t pollute error messaging. |

Three CodeRabbit findings arrived at 18:33Z against code that had already merged (#2887, #2888), so they surfaced on an unrelated open PR's diff instead of anywhere actionable. - pr_verifier: a repair reply of only thinking/metadata blocks was truthy, so the serialized envelope was returned as repair text and the parser failed on JSON the provider never sent. The repair path is now stricter than the parse path: no text blocks, or blank text, means no repair. The parse path keeps its json.dumps fallback for diagnostics. - enforce_gate_branch_protection: two of the three snapshot sites hardcoded strict: True, so --snapshot --allow-non-strict wrote a health artifact claiming strict enforcement that --apply would not create. - enforce_gate_branch_protection: the --context help still advertised 'Gate / gate' as the default; DEFAULT_CONTEXTS is 'summary', and #2858 is specifically about not requiring 'Gate / gate'. Co-authored-by: Cursor <cursoragent@cursor.com>
--allow-non-strict accepts a non-strict floor; an already-strict policy is still in sync. Snapshot desired.strict now mirrors that accepted current value so health_summarize does not render "✅ In sync" beside a True → False transition. Co-authored-by: Cursor <cursoragent@cursor.com>

- Around line 209-213: Add a focused test alongside
test_coerce_response_content_falls_back_to_json_for_unblocked_payloads that
passes _text_from_response_content multiple type="text" blocks containing one
JSON document split across boundaries, and assert the returned text is their
direct concatenation with no separator.
In `@tools/enforce_gate_branch_protection.py`:
- Around line 807-809: Add a regression test for the error path around the
snapshot-writing flow that invokes fetch_status_checks: configure it to raise
BranchProtectionError while --allow-non-strict is enabled, then assert the
written snapshot records the error and desired.strict is False. Keep the
existing successful fetch tests unchanged.
- Around line 824-832: Use the effective strict target computed in the snapshot
preparation flow, including the already-strict case under --allow-non-strict,
when calling update_status_checks around the context-update path near line 900;
do not pass the raw desired_strict value. Add an --apply regression test
covering an already-strict policy with context drift and verify strict
enforcement remains enabled.
