Every PR paid twice: the hand-enumerated matrix (18 test files, 22.6 min, ~$21 API measured on run 33263204465) ran serialized AHEAD of the strictly superior sliced lane via 'needs: evals' — 35.5 min wall and ~2x paid spend for the same diff. 14 of 17 rows carried no tier:, so periodic Opus benchmarks leaked into every PR (the e2e-plan row alone: 12/12 tests, 21.7 min, $7.28 — the wall-clock bound of ALL of CI). Parity receipt (static, pre-deletion): the sliced lane's gate census (49 files, derived from the runner itself) strictly contains all 18 matrix test files, plus 31 files the matrix never ran. Pure deletion — one revert restores it. The PR comment moved into slices-report (same '## E2E Evals' upsert marker, now sourced from slice artifacts + carrying the fail-closed reconciliation verdict). plan-slices loses the needs edge; the dead workflow-level EVALS_TIER env goes with it. test/evals-workflow-matrix.test.ts (and its KNOWN_MATRIX_GAPS / KNOWN_TIER_UNSET burn-down ratchets — retired: the sliced census makes 'every gate file runs' true by construction) is rewritten as test/evals-workflow-wiring.test.ts: matrix stays deleted, planner/executor/ report tier + slice-count agreement, both surviving lanes on the shared register-skills composite with its fail-fast verification loop, PR comment survival. Expected: PR eval wall 35.5 -> ~13 min, per-PR paid spend ~halved. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
