Laravel consent lifecycle policy simulator
A Laravel engineering simulator for versioned notices, purpose-specific consent, explainable processing decisions, withdrawal, erasure, retention, and audit evidence using synthetic data.
Project definition
Problem statement
A single consent checkbox does not represent which notice was shown, which purposes were accepted, when permission expires, what happens after withdrawal, or whether downstream processing stops.
The engineering problem is to model the lifecycle as versioned state and executable policy, enforce purpose-specific access, propagate changes to dependent work, and explain each decision without presenting a classroom prototype as legal compliance software.
Project objectives
- Create versioned notices and purpose-specific consent receipts.
- Evaluate whether a synthetic processing action is permitted at a given time.
- Stop prepared pending work when consent is withdrawn and make retries idempotent.
- Model access and erasure requests with erased and restricted retention outcomes.
- Measure exact decision accuracy, deterministic repetition, tests, coverage, and full-stack integration.
Project structure
Project components
Notice registry
Stores versioned notices, purposes, data categories, processors, retention rules, and effective dates.
Consent receipt service
Records a synthetic person decision against the exact notice and purpose versions shown.
Purpose gateway
Evaluates proposed processing against consent state, purpose, data category, actor, time, and documented exceptions.
Withdrawal service
Changes the receipt once, cancels prepared pending tasks transactionally, and remains safe under retries.
Rights workflow
Models access and erasure requests with due dates and separate erased and restricted record counts.
Audit explainer
Stores append-only policy events and reconstructs why a processing action was allowed, denied, stopped, or retained.
Methodology
Project workflow
- 01Load the synthetic study
The prepared notice, purposes, receipt, task, and retention record are seeded for controlled review.
- 02Record a decision
A synthetic person accepts or declines individual purposes and receives a versioned consent receipt.
- 03Evaluate processing
A proposed action is checked against the current receipt, purpose, actor, data category, and time.
- 04Change lifecycle state
Consent expires or is withdrawn, or an erasure request changes records to erased or restricted.
- 05Retain evidence
Processing, withdrawal, rights, and retention outcomes remain reviewable through structured records and audit events.
Demonstration scenario
A synthetic student accepts service delivery but declines optional analytics. A declared service action is allowed and analytics is denied with an explicit reason. Withdrawal then changes the receipt once and cancels the prepared pending processor task. An erasure request classifies ordinary data as erased and the declared classroom exception as restricted.
Engineering
Tools and method
- Application core
- Laravel models the versioned domain, authorisation, policy decisions, workflow transitions, and append-only audit events.
- Policy representation
- Explicit tables and evaluators represent purpose, data category, actor, time, receipt version, and exception conditions.
- Lifecycle services
- Database transactions implement processing, idempotent withdrawal, pending-task cancellation, erasure, restriction, and audit events.
- Review interface
- Vue presents the synthetic study, a processing-action form, the prepared receipt, and returned decision evidence.
- Data layer
- PostgreSQL stores synthetic records, versioned policies, receipts, requests, job effects, and audit history.
- Scenario testing
- Twenty time-controlled cases cover every policy branch, exact boundaries, actor and category scope, and decision precedence.
Testing
Evaluation
Evaluation measures
- Twenty exact decision and reason matches across the labelled scenario set
- Twenty deterministic scenarios across 2,020 total evaluations
- Correct idempotent withdrawal and one-time pending-task cancellation
- Correct separation of erased and restricted synthetic records
- Twenty-six passing tests, 101 assertions, and 98.3 percent application coverage
- Successful Laravel, PostgreSQL 18.6, Redis, HTTP, and persistence integration run
Project boundaries
- The project uses only synthetic people and data and is not a production consent-management platform.
- The policy model is an engineering interpretation for controlled experiments, not legal advice or a compliance certificate.
- Authentication, identity verification, and connections to real processors are outside the prepared laboratory.
- Every retention exception must be configured explicitly and remains visible in the audit explanation.
