Fakenet Command

model

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

One Nockchain burn (id wd-001) processed on BOTH Base (8453) and Arbitrum (42161) - double mint.

expectRejected inverts a CAUGHT exploit to a green 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.

Observed XCHAIN REPLAY: wd-001 misrouted to 42161 (expected 8453); expected each message unique per (destChainId,id), carries a sourceChainId, routed to its expected chain, under xchain.routing.
