aion_verify 3.8.0

A pure-Rust proof stack with no dependencies and no external solver. Tier 4 exhaustively checks a predicate over a bounded domain; tier 5 proves properties over UNBOUNDED, multi-variable domains via interval abstract interpretation, branch-and-bound refinement, and affine relational reasoning, with function contracts. Also finds faults you never wrote a predicate for -- index-out-of-bounds, overflow, unwrap, division by zero -- by exhaustive execution (std) or symbolically (profile-independent). Plus a tamper-evident SHA-512 hash-chain ledger and post-quantum (hash-based WOTS/Merkle) signatures. no_std, no unsafe.
