/**
 * Timeout policy for paid tests — five tiers instead of hand-tuned sprawl.
 *
 * Before this module the paid suite carried 46×300s, 46×120s, 44×360s,
 * 44×180s, 27×240s, 19×150s, 13×420s, 12×600s, 7×700s… hand-ratcheted
 * per test, several inflated to paper over the old 40-way in-shard
 * concurrency (session startup queued behind 39 siblings and ate the
 * budget before turn one — dead with the sharded runner's 1-file-per-shard
 * model). Pick the tier that matches the test's SHAPE; escape-hatch raw
 * literals stay legal with a justification comment (count-ratcheted by
 * test/eval-budgets-policy.test.ts).
 *
 * Every tier must fit inside the lane walls — pinned by the fit test in
 * test/eval-budgets-policy.test.ts against the sharded runner's
 * DEFAULT_SHARD_TIMEOUT_MS. Budget above the wall is fiction, not headroom.
