/**
 * C8 `lanes` selection and the mechanical preflight checks, pinned on tokens,
 * exit codes and the pregate.json contract. Fixture repos live under
 * os.tmpdir() (test/helpers/pregate-fixture.ts). Incident replays named in
 * the plan's P0-4 section, each caught locally before any remote gate:
 *   p0-4-stale-goldens          regen: a changed input, an unchanged output
 *   p0-4-scratch-script         strays: zz-probe.sh at the repository root
 *   p0-4-heavy-old-constant     literals: a nightly-only test keeps the old number
 *   p0-4-windows-lane-unrun     lanes: a Windows-only test file changes on Linux
 *   p0-4-pipe-hidden-failure    lanes: `false | tail` under pipefail is red
