Security governance layer

VaaS uses a security governance layer to reduce operational and key-person risk.

The governance layer include:

3-of-5 Multisig	Prevents single-key compromise for sensitive governance actions.
Execution Timelock	Gives LPs and monitoring systems time to observe high-impact changes before they take effect.
NAV Signer Quorum	Requires multiple authorized parties to validate NAV updates.
Strategy Whitelisting	Restricts capital deployment to approved strategies and venues.
Emergency Pause	Allows deposits, withdrawals, allocation, or redemption to halt during extreme market or security events.
Role-Based Permissions	Assigns limited privileges to curators, strategy managers, signers, guardians, and operators.

These controls create a more professionally managed vault environment than an unrestricted contract or discretionary offchain account.
