Readiness Report

Forfeit Flip carries a passing two-sided commit-reveal fairness report with a commitment-only peek surface.

Proves the fairness model and that the invariants are well-formed; the standalone verifier reproduces the coin-flip seed-leak contrast (100% vs ~50%).

Required Checks

lab-report-linked

Lab fairness report linked

pass

The forfeit-flip-fairness lab report (hash + snapshot root) is attached to the case.

fairness-invariants

Provable-fairness invariants

pass

Commitment-only peek, seed-hashlock (sha256(seed)==commit), and strictly increasing nonce all pass.

secret-redaction

Secret redaction

pass

Peek surface and evidence reference no server seed, client seed, or signing material.

Recommended Checks

badge-ready

Badge ready

pass

Eligible for a public trust badge; badge-forfeit-flip-verified is issued and signed.

settlement-residual

Settlement residual disclosed

warn

Fairness is fully trustless; settlement is bonded-cooperative + timeout-forfeit (HTLC-grade), not contract-grade forced payout — consensus cannot gate a payout on the game outcome.
