## What I do
I commit a Merkle proof to the AgentDB ledger to create an immutable audit trail. I hash the encrypted payload and store the transaction hash for tamper-evident logging.
## When to use me
Use this when:
- Data encryption is complete and you need to create an audit trail
- You're creating a tamper-evident record of the analysis
- You need to log the transaction for compliance requirements
## Key Concepts
- **Merkle Proof**: Cryptographic proof of data integrity
- **Transaction Hash**: SHA-256 hash of encrypted payload
- **Immutable Ledger**: Append-only storage for audit records
- **audit_logged**: State flag (goal state reached)
## Source Files
- `services/agentDB.ts`: Audit trail implementation
- `services/crypto.ts`: Hash generation
## Code Patterns
- Generate SHA-256 hash of encrypted payload
- Store transaction hash with metadata in AgentDB
- Return confirmation of audit commitment
## Operational Constraints
- Creates immutable record - ensure data is correct before committing
- Transaction hash used for future verification
- This is the final step - audit_logged: true means pipeline complete
