CRYPTOGRAPHER-SIGN-OFF.md captures the Tier A artifact review:
- APPROVED WITH GATES for F-Chain TFHE (LP-066/LP-134) and the
threshold-FHE compliance package (LP-019/LP-076/LP-167)
- Verified green: build, dudect bridges build, EC theories 0/0
admits, Lean 0 sorry, bridge map cites each axiom, Jasmin
algorithm shape correct, CT obligations correctly stated
- 4 minor findings, 2 informational
- 4 open gates:
GATE-1: dudect submission-grade run (10^9 samples)
GATE-2: jasminc -checkCT pass on production Jasmin
GATE-3: deployment runbook for F-Chain TFHE
GATE-4: Lean tactic-script transcription of EC proof
None of the gates require algorithm or code change; they are
about empirical confirmation and operational disclosure.
