Declaration Audit Logger
Component Detail
Description
Records a tamper-evident audit trail for all declaration lifecycle events including creation, delivery, reading, acknowledgement, and revocation. Provides compliance evidence for legally required confidentiality agreements.

Summaries
The Declaration Audit Logger creates a legally defensible, tamper-evident record of every significant event in a confidentiality declaration's lifecycle — from creation and delivery through to acknowledgement or revocation. In the event of a legal dispute, HR investigation, or regulatory audit, this component provides irrefutable evidence of when a declaration was sent, when it was read, and when it was signed. For organizations operating in regulated industries or managing large driver workforces, this audit capability is not optional — it is a compliance requirement. It directly reduces legal risk and positions the platform as enterprise-ready for organizations with strict governance obligations.
The Declaration Audit Logger is a medium-complexity backend component with no external service dependencies, which simplifies its delivery timeline. However, it is a cross-cutting concern that must be integrated by every other declaration lifecycle component — creation, delivery, acknowledgement, and revocation flows all must invoke the logger at the appropriate moment.
This creates coordination overhead: integration points must be defined and agreed upon with the teams building those features before logging can be wired in. Test coverage must validate immutability guarantees — audit entries must not be updatable or deletable via normal application paths. The `exportAuditLog` function adds reporting complexity and should be scoped carefully to avoid scope creep.
Declaration Audit Logger persists `declaration_audit_event` records for each lifecycle transition, providing a chronological event stream per declaration. Each log entry should capture: `declarationId`, `eventType` (enum: created/sent/read/acknowledged/revoked), `actorId`, `actorRole`, and `timestamp`. Immutability must be enforced at the database level — consider an append-only table with no UPDATE/DELETE grants for the application role, or a check constraint that prevents status overwrites. `getAuditLog(declarationId)` returns the ordered event list for a single declaration.
`exportAuditLog(orgId, dateRange)` performs a bulk query filtered by org and timestamp range, suitable for CSV or JSON export. All writes should be transactional with the triggering domain operation to avoid partial state where an action succeeds but its audit entry is missing.
Responsibilities
- Log all declaration state transitions with timestamps
- Record actor identity (coordinator or driver) for each event
- Persist audit entries immutably to prevent tampering
- Support audit log export for compliance review
