Cryptographic Chain of Custody
To guarantee that critical HR actions are never tampered with or retroactively altered, AI SoloHR implements a mathematical chain of custody for all audit logs. Every log entry is cryptographically linked to its predecessor using a SHA-256 hash value.
How the chain is built
Each audit log entry contains a mathematical proof.
Neon Database-Level Write-Lock Protection
Under the Compliance Plus plan, database-level triggers (pg_trigger) prevent any UPDATE or DELETE operations on the AuditLog table. Even with raw database access, records are strictly append-only and cannot be altered or removed without raising exceptions.
Running the Integrity Verification Flow
Platform administrators can verify the mathematical integrity of the audit chain directly from the Admin Portal. The system performs a live verification by recalculating the hash sequence starting from the root entry.
Verification Steps
Perform the chain check within the administrative interface.
What to do before and after this step
Most product help actions are easier when the right context is already in place. Before taking the step on this page, make sure the related case, facts, and people are clear. After finishing it, the next move is usually another workflow step such as checking documents, assigning follow-up, or reviewing a draft.
- Use the help article while working inside a real case or workflow
- Keep the surrounding facts, dates, and documents organized first
- If the result affects sensitive communication, review it before sending or sharing it
Support boundary
This help content explains publicly available product workflows. It does not promise hidden features, custom integrations, legal review, or automated compliance outcomes beyond what the product already does today.
AI SoloHR is designed to support case records, tasks, documents, timelines, and reviewed AI drafts inside one workflow. It is not a substitute for legal, medical, benefits, or policy review where those are needed.

Frequently asked questions
Can an administrator bypass the database trigger?
No. The prevent_audit_log_mutation database trigger blocks all update and delete queries at the database engine level, ensuring raw immutability.
What happens if a log entry is manually modified?
If a log entry is modified or deleted, the next log's previousEntryHash will no longer match the recalculated hash. The integrity check will immediately fail and pinpoint the exact ID where the break occurred.
