 * signal from the healthy specs. Quarantining them keeps the rest of the
 * suite as a live per-push gate while each file is re-pinned to the

/**
 * PROBATION (2026-07-20): specs that run on every push but do NOT gate the
 * Core E2E verdict. CI runs the suite in two passes per shard, selected by
 * PULSE_E2E_TIER: "stable" (everything not listed here — gating) and
 * "probation" (this list — reported, continue-on-error). Locally, with
 * PULSE_E2E_TIER unset, both tiers run together exactly as before.
 *
 * Seeded from per-spec failure data mined out of the "Core E2E Tests"
 * workflow's failed-shard logs for the 31 completed main runs between the
 * 2026-07-18 quarantine delist and 2026-07-20: every spec that failed or
 * retry-flaked within the 10 most recent completed runs starts here; specs
 * whose last incident is older already satisfy the promotion rule below.
 *
 * Promotion rule — a spec earns its way OUT of this list (into the gating
 * stable tier) after 10 consecutive Core E2E runs on main in which it
 * neither failed nor went flaky (a retry-pass reported as "flaky" counts as
 * an incident — the retry hid it from the verdict, not from this ledger).
 * Demotion rule — one flake on main demotes a stable spec back to this
 * list, restarting its count. A spec leaves the suite only via QUARANTINE
 * (still-rotted, doesn't run) or deliberate deletion; probation is for
 * specs that run green sometimes but haven't yet proven they always do.
