Your Vault (Zcash P2SH t-addr)
├── Path 1 (Normal):  you + NEXUS co-sign — used for instant withdrawals
├── Path 2 (Renewal): renewal key + NEXUS — for key rotation
└── Path 3 (Escape):  you alone, after 16,128 blocks (~2 weeks)
    → Broadcast your pre-signed exit tx — no permission required

// Returns: { success, txid, status, path, confirmed? }

  { waitForConfirmation: true }
);
