The identical fixer-dedup prompt edit has now failed to land on three consecutive attempts: re-filed as feedback issue [ci-scan-feedback] Read ci-fix head.ref via list/get, not search, to close dedup gap #134305 (2026-09-19) after a failed PR push, exactly as [ci-scan-feedback] Read ci-fix head.ref via list/get, not search, to close dedup gap #134276 (2026-09-19) and [ci-scan-feedback] Read ci-fix head.ref via list/get, not search, to close dedup gap #132616 (2026-08-21) did. The failure mode it fixes keeps reproducing. [ci-scan-feedback] Read ci-fix head.ref via list/get, not search, to close dedup gap #134305

• Empirical confirmation (verified this tick). search_pull_requests result items expose no head field (confirmed against [ci-fix] Needs review: mark Apple runner interop as safe (refs #134061) #134186, [ci-fix] Mark Apple test runner LibraryImports safe (refs #134061) #134134, [ci-fix] Needs review: dual-stack accept-reset socket test fails on Windows/Linux (refs #133778) #133925, [ci-fix] Fix Android NativeAOT template for updated memory safety rules #134323 — all head.ref MISSING), whereas list_pull_requests and pull_request_read get both return head.ref. Step 3 instructed the fixer to parse head.ref from search results, so the ci-fix/<kbe>- dedup map was always empty and never matched.

Proposed edits

• .github/workflows/ci-failure-fix.md (Step 3 — Existing-artifact dedup, ~line 211) — replace the "enumerate every [ci-fix] PR ... parsing head.ref" instruction with an explicit note that search_pull_requests returns no head field, and direct the fixer to read head branches from list_pull_requests (state: open) for open candidates and pull_request_read get for merged/closed candidates. Add that an empty branch map means "not yet enumerated", not "no open PR".

Expected behavior change

The next fixer run builds the <kbe> -> [PRs] dedup map from head.ref values actually present in the response — list_pull_requests for open PRs and pull_request_read get for merged/closed ones — instead of from search_pull_requests items that never carry a head field. This closes the residual dedup gap that let help-wanted PR #134186 be filed against KBE #134061 while confident #134134 was already open: the fixer detects the open ci-fix/134061- branch and skips with open fix PR #134134 already exists rather than opening a duplicate. Landing directly (not as a re-filed feedback issue) because this identical prompt change has now orphaned three times on failed PR pushes (#132616, #134276, #134305).

Resolves #134305
