Compose random-word dispatch, reference mapping, compression and the block update into one complete active-cell implementation. Prove the represented matrix becomes exactly
Spec.Argon2.fillBlock's matrix and retain the filling allocation, public pointers, callee-saved registers, permissions and MXCSR within the derive memory frame.Prove the independent-address cache survives the cell update, including its cached block at scratch offset 6144. Connect trace equality to the reviewed filling step's reference log: Argon2i requires no secret equality, and Argon2d/id require only equality of the specified data-dependent reference indices.
Builds on #502. Inline implementation and proofs only; no specification, TCB, public API or generated assembly changes.
Validation: targeted Lean correctness and trace builds, standard-axiom and compiler-override audits, specification-origin audit, Lean import/proof-speed checks, and
git diff --check. Full checks run in CI.
