Declaration Acknowledgement Service
Component Detail
Description
Handles the lightweight e-signature acknowledgement flow, recording a checkbox confirmation and exact UTC timestamp when a driver confirms they have read the confidentiality declaration. Writes a tamper-evident acknowledgement record to the database.

Summaries
The Declaration Acknowledgement Service provides the legal and operational foundation for confirming that each driver has genuinely read and accepted their confidentiality agreement. By capturing a timestamped checkbox-based e-signature stored as a tamper-evident database record, the organization gains a defensible proof of informed consent that can be produced in legal disputes, audits, or regulatory inspections — offering substantially stronger protection than manual or paper-based processes. The service's requirement that drivers scroll through the complete document before acknowledging ensures that acknowledgement represents genuine engagement rather than a click-through formality, significantly strengthening the legal standing of each recorded consent and reducing the organization's exposure to confidentiality breach claims.
The Declaration Acknowledgement Service is a medium-complexity backend component with two dependencies: declaration-repository and declaration-audit-logger. Its delivery is sequentially gated by the declaration-management-service, as declarations must exist and be delivered before acknowledgements can be recorded — plan this dependency explicitly in the sprint schedule. Testing scope includes valid acknowledgement recording, eligibility validation enforcing full-scroll completion, duplicate acknowledgement prevention, immutability verification of post-write records, and audit event emission with correct schema. The tamper-evident record requirement adds a dedicated QA step to confirm that no update path exists on acknowledgement records.
Timeline risk is low given the focused scope, but schema alignment with the declaration-audit-logger team must be completed before integration testing to avoid a late-breaking contract mismatch.
The Declaration Acknowledgement Service is a focused backend service managing the e-signature step of the declaration workflow through four interfaces: recordAcknowledgement(declarationId, driverId, timestamp) writes a tamper-evident declaration_acknowledgement record with exact UTC timestamp; validateAcknowledgementEligibility(declarationId) enforces the full-scroll precondition before acknowledgement is permitted; getAcknowledgementRecord(declarationId) retrieves the stored record; isAcknowledged(declarationId) provides a fast boolean status check. It depends on declaration-repository for persistence and declaration-audit-logger for event emission. The tamper-evident constraint is critical: acknowledgement records must be implemented as insert-only with no update path whatsoever — any mutation after write should be rejected at the service layer, not just the database layer. Audit events must include declarationId, driverId, and UTC timestamp to satisfy traceability requirements.
isAcknowledged should be implemented as a lightweight indexed query to support high-frequency status checks from the declaration management service.
Responsibilities
- Record driver acknowledgement with UTC timestamp
- Validate that declaration was fully scrolled before acknowledgement
- Update declaration status to acknowledged in the repository
