Fakenet Command

model

Positive proof of the forfeit-dice fairness invariants over a resolved round.

Peek surface is commitment-only (no seed); revealed seeds hash to their commitments; nonce strictly increases; the published roll lives in the unbiased [0,9999] band (rejection-sampled shax(jam[server client nonce]) mod 10000).

Honest limit: this proves the MODEL and that the invariants are well-formed, not the compiled Hoon (the compile-gate fixture covers that). The standalone forfeit-dice verifier proves the chi-square uniformity + rejection-sampling debias separately. 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.

Run Steps

Peek the commitment-only surface

Invariant Results

Peek surface never exposes an unrevealed seed

critical

pass

Observed peek surface clean: 7 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]; expected nonceSequence is a strictly-increasing numeric sequence (replay/nonce safety).

Published roll lives in the unbiased [0,9999] band (modulo-bias removed by rejection sampling)

high

pass

Observed 4217; expected 0 <= peekSurface.roll <= 9999.
