Environment

gRPC Endpoint

n/a

Fakenet Command

model

Positive proof of the forfeit-roulette fairness invariants over a resolved European red/black round.

Peek surface is commitment-only (no seed); revealed seeds hash to their commitments; nonce strictly increases.

The house edge is the single green zero (1/37); the wheel itself is unbiased and the pocket is recomputable from public reveals.

Honest limit: this proves the MODEL and that the invariants are well-formed, not the compiled Hoon (the compile-gate covers that). Real-VM poke/peek awaits generic-cause nockapp-run.

Next Actions

  1. Replace mock poke and peek execution with local fakenet adapter calls.
  2. Replace command-backed fakenet metadata probes with stable gRPC-native probes once node surfaces are available.
  3. Persist generated reports under a project workspace.
  4. Add app-specific invariant packs as the NockApp interface stabilizes.

No invariant packs referenced.

Run Steps

Peek the commitment-only surface

peek

pass

Invariant Results

Peek surface never exposes an unrevealed seed

critical

pass

Observed peek surface clean: 6 field(s), no unrevealed secret; expected no unrevealed seed/secret in the peek surface at peekSurface.

Revealed seeds hash to their commitments (provable fairness)

critical

pass

Observed all 2 revealed seed(s) hash to their commitment; expected sha256(seed) == commit for every revealed pair under reveals.

Nonce strictly increases (replay safety)

high

pass

Observed [0,1,2,3,4]; expected nonceSequence is a strictly-increasing numeric sequence (replay/nonce safety).
