History
mrwulf f544b64e95 THE SIGNATURE APEX on the risc0 fork: verify_accepts_iff, button-enforced 
Replicates dalek's apex with this fork's sha2-0.10 adaptation: the hash
oracle is the single monomorphic sha512_hash3(R, A, m) call (no foreign
types in its signature — the 0.10 Sha512 alias cannot be declared opaque),
and extraction runs --no-default-features so the error path avoids boxed
dyn-Error.

- gen/CurveSig: the extracted verify glue, definitionally welded to the
  proven model (TypesExternal/FunsExternal import CurveField; every curve
  and scalar call is a certified definition).
- Proofs/SigApexSpec.lean (unchanged from dalek): verify_loop_full (the
  32-byte comparison = array equality; axiom cone exactly the standard
  three) and verify_accepts_iff — accept IFF compress([s]B - [k]A) = R
  byte-for-byte, SHA-512 opaque.
- check.sh Phase 3b: the apex axiom cone is enforced to be EXACTLY
  [propext, Classical.choice, Quot.sound, ed25519.Signature,
   verifying.sha512_hash3, ed25519.Signature.to_bytes,
   signature.error.Error, signature.error.Error.new]
  - zero curve, scalar, or backend axioms.

Full check.sh green: 17 standard certificates + the apex audit.
