Summary

Implements a comprehensive emergency pause mechanism for the PrivacyLayer privacy pool contract.

Changes

Contract Layer

  • pause() - Updated to accept pause_reason parameter for audit trail
  • unpause() - Updated to emit timestamp
  • is_paused() - New function returning pause state with PauseInfo
  • emergency_withdraw() - New function for admin fund recovery during security incidents

Storage

  • Added PauseInfo struct with:
    • pause_timestamp: u64 - When pool was paused
    • pause_reason: String - Reason for audit trail
    • paused_by: Address - Admin who initiated pause
  • Added DataKey::PauseInfo for persistent storage
  • Added pause info storage functions in storage/config.rs

Events

  • Updated PoolPausedEvent with pause_reason and imestamp
  • Updated PoolUnpausedEvent with imestamp
  • Added EmergencyWithdrawEvent for transparency

Errors

  • PoolNotPaused - Emergency withdraw requires paused pool
  • EmergencyWithdrawExceedsBalance - Amount > contract balance
  • InvalidEmergencyAmount - Amount must be > 0

Tests

  • est_is_paused_returns_false_initially
  • est_is_paused_returns_true_after_pause
  • est_pause_is_idempotent
  • est_unpause_is_idempotent
  • est_emergency_withdraw_requires_paused_pool
  • est_emergency_withdraw_requires_admin
  • est_emergency_withdraw_rejects_zero_amount
  • est_emergency_withdraw_rejects_excessive_amount
  • est_emergency_withdraw_succeeds

Security Considerations

  • Emergency withdraw bypasses privacy guarantees (intentional for security incidents)
  • Pool MUST be paused before emergency withdrawal
  • All operations emit events for audit trail
  • Non-admin cannot perform any admin operations

Acceptance Criteria

  • Pause/unpause functions implemented
  • Access control enforced
  • All operations respect pause state
  • Events emitted correctly
  • Tests added for all new functionality
  • Documentation via code comments

Closes #15
