The governed on-chain registry (AereCryptoRegistry) maps every registered
post-quantum algorithm to a live verifier: measured 2026-08-15, all 5
algorithms (Falcon-512, Falcon-1024, ML-DSA-44, SLH-DSA-128s, SHAKE256)
resolve to the live NIST precompiles 0x0AE1..0x0AE5, status active, and the
registry contract itself bears code. So 'crypto agility' is not a slide: adding
a scheme or retiring one is a governed registry write, not a hard fork.
Negative control: a planted fake verifier address is caught. Read-only,
eth_call and eth_getCode only. Building this caught two of my own decode bugs
(wrong selector, wrong tuple word) before they became a false public claim,
which is what verification-before-publication is for.
