//
// Proves the full stack works as a *system*, not as isolated parts. A custom
// MEDIUM-tier agent:
//   1. is registered + started through the consolidated AgentRegistry
//   2. receives untrusted input over the EventBus (subscribe channel ACL)
//   3. runs it through the real injection-sanitization pipeline
//   4. performs an observable side effect (writes a file to disk)
//   5. emits a result via act() — enforces the publish channel ACL AND
//      records a tamper-evident DecisionLedger entry
//   6. the driver independently verifies that ledger entry + the chain
//
// No mocks. Every layer is the real one. If any layer is broken or
// unimplemented this script names the failing layer and exits non-zero.
//
// Run:  npm run e2e:proof   (or: npx tsx examples/e2e-proof.ts)
