Fakenet Command

model

NEGATIVE CONTROL (expectRejected=true): a cross-chain exploit that the invariant MUST catch.

Mint at 3 confirmations, below requiredConfirmations=12 (reorg double-spend risk).

expectRejected inverts a CAUGHT exploit to a green PASS (a signed proof-of-prevention).

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.

Invariant Packs

No invariant packs referenced.
