An experimental protocol that distributes erasure-coded data shards across an n-dimensional hypercube topology and periodically rotates their placement using automorphisms of the cube. Each rotation is committed to a verifiable, blockchain-anchorable epoch ledger — combining fault tolerance, continuous cryptographic auditability, and moving target defense in one storage substrate. Integrates with Project Looking Glass self-healing architecture and Dual-Layer Digital Permanence anchoring. (draft-reilly-hdrp-00)
