Audit Metadata¶

Audit Information:

• Date: 2025-10-05 04:05 UTC
• Auditor: AI Assistant
• Audit Version: 2.0 (Follow-up audit)
• Project: Dashtam
• Branch/Commit: development

Scope:

• Total Items Reviewed: 41 API endpoints across 5 routers
• Coverage: Complete REST API (all v1 endpoints)
• Focus Areas: RESTful compliance, schema organization, code quality

Status:

• Current/Historical: Historical record (point-in-time snapshot)
• Follow-up Required: No (perfect score achieved)

Audit Objectives¶

Evaluate Dashtam REST API compliance with RESTful architectural principles and identify any deviations from best practices.

Primary Objectives:

1. RESTful Compliance: Verify all endpoints follow REST principles (resource-based URLs, proper HTTP methods, status codes)
2. Code Organization: Ensure complete separation of concerns (schemas separated from routers, no inline models)
3. Architecture Quality: Validate router independence, clean dependencies, no duplicates
4. Production Readiness: Assess test coverage, documentation, security features

Success Criteria:

• All endpoints use resource-based URLs (not action-based)
• Proper HTTP methods (GET, POST, PATCH, DELETE) used correctly
• All Pydantic schemas separated into dedicated schema files
• Zero inline models in router files
• No duplicate or conflicting router implementations
• Comprehensive test coverage (>70%)

Scope and Methodology¶

Audit Scope¶

Included:

• All API v1 endpoints (/api/v1/*)
• Router architecture and organization (src/api/v1/)
• Schema organization (src/schemas/)
• Cross-router dependencies
• Test coverage and quality
• Security implementations

Excluded:

• Internal service logic (covered by separate audits)
• Database models (separate scope)
• Frontend/UI considerations

Methodology¶

Approach:

1. Automated Scanning: Search for inline schemas using regex class.*\(BaseModel\) in router files
2. Manual Review: Examine each router file for RESTful compliance
3. Testing Verification: Run full test suite (make test)
4. Code Quality: Verify linting and formatting pass (make lint, make format)

Tools Used:

• grep/ripgrep - Pattern searching for inline schemas
• pytest - Test execution and coverage reporting
• ruff - Linting and code formatting
• Manual inspection - Architectural review

Criteria:

• REST API Standards: HTTP/1.1 specification, REST architectural constraints
• Code Organization: FastAPI best practices, separation of concerns
• Security Best Practices: OWASP API Security Top 10
• Testing Standards: >70% code coverage, all tests passing
