Garry TanandClaude Fable 5 056bc61a26 feat(ci): sliced paid lane (planner -> 6 executors -> fail-closed report)
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
