# VS-04: Immutable Audit Trail (GDPR/Compliance)
**Status:** ✅ IMPLEMENTED
**Date:** 2026-08-07
**AGENTS.md v16.0:** 13/13 ✅
---
## Overview
Workstream I implements VS-04 — an **immutable, append-only audit trail** for all model operations, with full **GDPR right-to-be-forgotten** support via redaction (soft delete, not hard delete).
**Key Properties:**
- **Immutable:** INSERT-only, no UPDATE/DELETE on core events
- **Traced:** Every event linked via `correlation_id`
- **GDPR-Compliant:** Right-to-be-forgotten via anonymization (Article 17)
- **Regulatory:** 7-year retention (FSS/GDPR/PCI-DSS requirements)
- **Forensic:** IP address, user agent logged for investigation
---
## Database Schema
### `compliance.audit_events` (immutable)
```sql
CREATE TABLE compliance.audit_events (
id UUID PRIMARY KEY,
event_type VARCHAR(100), -- MODEL_CREATED, APPROVAL_PROPOSED, MODEL_ACTIVATED, SELL_EXECUTED, etc.
entity_type VARCHAR(50), -- MODEL, APPROVAL, SELL_DECISION, TRADE_EXECUTION
entity_id UUID,
actor_email VARCHAR(255), -- Who performed the action
actor_role VARCHAR(50), -- MAKER, CHECKER, SRE, SYSTEM

ip_address INET,
user_agent TEXT,
published_at TIMESTAMPTZ,
correlation_id UUID, -- Links related events
revision INT
);
```
**Indexes:** entity_id, event_type, actor_email, event_at, correlation_id (query performance)
### `compliance.gdpr_retention` (GDPR tracking)
```sql
CREATE TABLE compliance.gdpr_retention (

purge_status VARCHAR(50), -- PENDING, PURGED, EXCEPTION
purged_at TIMESTAMPTZ,
exception_reason TEXT,
published_at TIMESTAMPTZ,
revision INT
);
```
**Retention Policy:** 7 years from event creation (automatic calculation in handler)
---

## GDPR Compliance: Right-to-Be-Forgotten
### Redaction Process (Soft Delete, Not Hard Delete)
**API Call:**
```bash
POST /compliance/gdpr-request
{
"customerId": "customer-uuid",
"reason": "Right to be forgotten (GDPR Article 17)"
}
```
**Execution Flow:**
1. **Request Submission** (`SubmitGdprRequestEndpoint`)
- Accepts GDPR request
- Returns `202 Accepted` with tracking ID
- Queues Hangfire job for async processing
2. **Redaction Job** (`GdprRedactionJob`)
- Find all audit events linked to customer (via `gdpr_retention` table)
- Update `gdpr_retention``purge_status = 'PURGED'`
- Anonymize personal data in audit_events via JSONB update:
```sql
UPDATE compliance.audit_events
SET details = jsonb_set(details, '{actor_email}', '"<redacted>"')
WHERE event_id IN (SELECT event_id FROM gdpr_retention WHERE customer_id = $1)
```
- Log redaction completion
3. **Result**
- Audit trail remains intact (immutable, for forensics)
- Personal data anonymized (email → `<redacted>`, customer_id → `<purged>`)
- Compliance: GDPR Article 17 satisfied
- 7-year retention still enforced (FSS/regulatory)
### Data Categories Tracked
- `PII` — Personally identifiable information
- `EMAIL` — Email addresses
- `TRADING_HISTORY` — Trading decisions/history
- `PORTFOLIO_DATA` — Portfolio composition
- `PAYMENT_INFO` — Payment/billing info
---
## Code Structure (AGENTS.md v16.0 Compliant)
### Domain Entities
- **`AuditEvent.cs`** — Immutable event entity + type enums
- **`GdprRetention.cs`** — GDPR retention tracking entity
### Data Access
- **`AuditSql.cs`** — Dapper queries (INSERT, SELECT, UPDATE for redaction)
### Business Logic (Handlers)
- **`LogAuditEventHandler.cs`** — Log event (idempotent)
- **`ProcessGdprRequestHandler.cs`** — Queue GDPR redaction job
### Background Jobs
- **`GdprRedactionJob.cs`** — Execute redaction (Hangfire)
### API Endpoints (FastEndpoints)
- **`QueryAuditEventsEndpoint.cs`** — GET /audit/events (filtered queries)
- **`SubmitGdprRequestEndpoint.cs`** — POST /compliance/gdpr-request
### Tests
- **`AuditTrailTests.cs`** — Unit + integration tests (insert, query, redaction)
---
## Integration with Other Slices
### VS-03 (Approval Workflow)
- On `APPROVAL_PROPOSED`: LogAuditEventHandler queued
- On `APPROVAL_APPROVED`: LogAuditEventHandler queued
- On `MODEL_ACTIVATED`: LogAuditEventHandler queued
- Evidence links stored: PBO/DSR/OOS artifacts
### Model Operations
- On model creation: LogAuditEventHandler queued
- On model activation: LogAuditEventHandler queued
- On backtest completion: LogAuditEventHandler queued
### Sell Decision Engine
- On sell signal generation: LogAuditEventHandler queued
- On trade execution: LogAuditEventHandler queued
---
## Regulatory Compliance
### FSS (금감원) — 7-Year Retention
- Audit trail retained for 7 years from event creation
- Immutability enforced (no deletion, only redaction for GDPR)
- Model operations fully traced with correlation_id
### GDPR (EU) — Right-to-Be-Forgotten
- Article 17: Right to erasure/redaction
- Implementation: Soft delete via JSONB anonymization
- No hard deletion (forensics still available, but anonymized)
- GDPR request tracking & audit log
### PCI-DSS — Payment Card Security
- IP address logged (forensics)
- User agent logged (device tracking)
- Event trail immutable (no tampering)
---
## Testing
### Unit Tests
- Event logging (INSERT)
- Query with filters (SELECT)
- GDPR retention tracking (INSERT)
- Redaction logic (UPDATE anonymization)
### Integration Tests
- Full end-to-end event logging
- GDPR request → redaction pipeline
- Query filtering accuracy
- Pagination
### Test File
- `tests/KArtSell.Integration.Tests/Compliance/AuditTrailTests.cs`
**Run:**
```bash
dotnet test KArtSell.sln --filter "Category=Compliance" -c Release
```
---
## Observability
### Logging
- Event logged with correlation_id, entity_id, actor_email
- GDPR requests tracked with gdpr_tracking_id
- Redaction completion logged with record count
### Metrics (Future)
- Audit event volume (events/day)
- GDPR requests submitted (requests/month)
- Redaction completion time (SLA: <24 hours)
- Query response time (SLA: <1s for 1000-record range)
---
## Security & Compliance Checklist
- [x] Immutability enforced (INSERT-only via code)
- [x] Correlation_id traceability (all events linked)
- [x] GDPR redaction implemented (soft delete)
- [x] 7-year retention policy (FSS)
- [x] IP address + user agent logged (PCI-DSS)
- [x] Evidence linkage (PBO/DSR/OOS artifacts)
- [x] RBAC on query endpoints (Compliance Officer role)
- [x] Async redaction (Hangfire, no blocking)
- [x] Idempotent operations (safe replay)
- [x] Error handling & logging (audit trail never lost)
---
## Related Specifications
- **VS-00:** PIT envelope (published_at, correlation_id, revision)
- **VS-02:** Data governance foundation
- **VS-03:** Approval workflow (generates events)
- **AGENTS.md v16.0:** Governance framework

This slice implements a maker-checker approval workflow for model activation with separation of duties and immutable audit trail.
## Architecture
### State Machine
```
DRAFT (created)
PROPOSED (maker submits)
├→ APPROVED (checker approves)
│ ↓
│ ACTIVE (SRE activates)
└→ REJECTED (checker rejects)
```
### RBAC Roles
- **Maker:** Creates approval proposals (own proposals only)
- **Checker:** Reviews and approves (must be different from Maker)
- **SRE:** Activates approved proposals
### Components
1. **ApprovalProposal (Domain Entity)**
- Model approval proposals with PIT tracking
- Stores justification, effective date, approval notes
- Immutable except for status transitions
2. **ApprovalWorkflowSql (Data Access)**
- Dapper queries for INSERT/SELECT operations
- PIT tracking with correlation_id
- No UPDATE/DELETE (append-only)
3. **ApprovalWorkflowPolicy (Domain Logic)**
- State machine validation
- RBAC enforcement
- Event generation
4. **Handlers (Application Layer)**
- CreateApprovalProposalHandler
- ApproveApprovalHandler
- ActivateModelHandler
- Outbox events on each state change
5. **Endpoints (HTTP Layer)**
- POST /approvals (create proposal)
- GET /approvals (list proposals)
- POST /approvals/{id}/approve (approve proposal)
## API Contracts
### POST /approvals (Create Proposal)
Request:
```json
{
"modelId": "uuid",
"effectiveAt": "2026-09-15",
"justification": "Model passed OOS testing; PBO score 0.95"
}
```
Response (201):
```json
{
"id": "uuid",
"status": "DRAFT",
"createdAt": "2026-08-07T10:00:00Z"
}
```
### GET /approvals (List Proposals)
Query Params:
- `status=PROPOSED` (filter by status)
- `modelId=uuid` (filter by model)
- `limit=50`, `offset=0` (pagination)
Response (200):
```json
{
"items": [
{
"id": "uuid",
"modelId": "uuid",
"status": "PROPOSED",
"createdBy": "maker@company.com",
"createdAt": "2026-08-07T10:00:00Z",
"justification": "..."
}
],
"total": 1,
"pages": 1
}
```
### POST /approvals/{id}/approve (Approve Proposal)
Request:
```json
{
"approvalNotes": "PBO verified, OOS metrics acceptable",
"evidence": [
{"type": "PBO_SCORE", "url": "s3://evidence/pbo-0.95.json", "comment": "Confirmed"},
{"type": "OOS_RETURN", "url": "s3://evidence/oos-returns.csv", "comment": "Acceptable"}
]
}
```
Response (200):
```json
{
"id": "uuid",
"status": "APPROVED",
"approvedAt": "2026-08-07T11:00:00Z"
}
```
## Database Schema
### approval_proposals
```sql
CREATE TABLE model_operations.approval_proposals (
id UUID PRIMARY KEY,
model_id UUID NOT NULL,
status VARCHAR(50), -- DRAFT, PROPOSED, APPROVED, ACTIVE, REJECTED
created_by VARCHAR(255),
created_at TIMESTAMPTZ,
justification TEXT,
effective_at DATE,
proposed_at TIMESTAMPTZ,
approved_by VARCHAR(255),
approved_at TIMESTAMPTZ,
approval_notes TEXT,
activated_by VARCHAR(255),
activated_at TIMESTAMPTZ,
published_at TIMESTAMPTZ,
revision INT,
correlation_id UUID
);
```
### approval_evidence
```sql
CREATE TABLE model_operations.approval_evidence (
id UUID PRIMARY KEY,
approval_proposal_id UUID NOT NULL,
evidence_type VARCHAR(50), -- PBO_SCORE, DSR_METRIC, OOS_RETURN, BACKTEST_REPORT
evidence_url TEXT,
reviewer_comment TEXT,
published_at TIMESTAMPTZ,
correlation_id UUID
);
```
### approval_events
```sql
CREATE TABLE model_operations.approval_events (
id UUID PRIMARY KEY,
approval_proposal_id UUID NOT NULL,
event_type VARCHAR(50), -- CREATED, PROPOSED, APPROVED, REJECTED, ACTIVATED
actor_email VARCHAR(255),
event_at TIMESTAMPTZ,
details JSONB,
published_at TIMESTAMPTZ,
correlation_id UUID
);
```
## Tests
Unit tests cover:
- RBAC enforcement (Maker, Checker, SRE roles)
- Separation of duties (Checker ≠ Maker)
- State machine transitions
- RBAC violations
Run tests:
```bash
dotnet test --filter "ApprovalWorkflowPolicyTests"
```
## AGENTS.md v16.0 Compliance
-**SOLID:** Separate Endpoint/Handler/Policy/Sql per operation
-**Complexity:** Each handler ≤200 lines
-**Audit:** All state changes logged with correlation_id
-**Necessity:** Grounded in VS-03 SLICE_SPEC
-**Normalization:** 3NF schema, append-only events
-**Simplicity:** State machine clearly visible
-**Pattern:** Vertical Slice standard
-**Guardrails:** RBAC enforced, no privilege escalation
-**Traceability:** Correlation_id + evidence linking
-**Safety:** Idempotent, rollback-safe
-**Maturity:** Spec complete before code
-**Right-Way:** No shortcuts, formal approval workflow
-**Debt:** No new tech debt
## Related Specifications
- **VS-00:** PIT envelope (published_at, correlation_id, revision)
- **VS-02:** Governance foundation (data sources, policies)
- **VS-04:** Audit trail (events logged by this slice)
- **Compliance:** Maker-checker separation, evidence linkage

**Status:** ✅ IMPLEMENTATION COMPLETE
