The parity-phase re-platform: evals.yml gains a second, sliced lane driven by scripts/test-paid-shards.ts — the SAME engine local eval:bg:gate uses, so CI and local share one selection engine. - plan-slices: ONE planner (fetch-depth 0 — the only job needing history) emits the manifest; selection fails open to run-all, never per-slice (the divergence class is structurally dead) - eval-slices: 6-way matrix consuming the manifest; PTY seed + skill-registration steps run unconditionally (idempotent — a sliced lane cannot key them on suite names); aggregate spawn budget 6 x EVALS_JOBS=2 x EVALS_CONCURRENCY=2 = 24 lane-wide (the matrix's 40-way per row queued session startup behind 39 siblings — the timeout-flake family root); slice results + spooled shard logs uploaded as artifacts - slices-report: reconciles slice artifacts against the manifest FAIL-CLOSED via --report — a slice whose artifact never landed, or a planned shard nobody reported, is a failure, not an absence - sequenced needs: evals so provider concurrency never doubles while both lanes coexist; the matrix + its ratchets are deleted after demonstrated parity (intersection + expected-additions comparison) - workflow_dispatch gains evals_all (default true) for parity runs and post-merge smokes — a dispatch can never silently select zero Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
