The real leak vectors ranked, the non-negotiables at any size, a three-rung maturity ladder that mostly stops at rung two, and rotation as a rehearsed muscle with two-key overlap.
The honest three algorithms, layered key design including the abuse limits everyone forgets (per victim, not per attacker), the 429 contract, and operational rules — fail open, shadow mode, degrade before deny.
