Build Pack §4, §13 — Promotion Gate: A challenger cannot become active without: (1) stored promotion decision, (2) minimum sample window, (3) required Chaos tests, (4) zero unresolved critical violations, and (5) rollback record. The prior worker is never deleted — the rollback pointer is retained indefinitely.
