Core Principles
01
TDD First
Every feature starts with failing tests. No exceptions.
- Write tests before implementation
- Red → Green → Refactor cycle
- 90%+ code coverage on critical paths
02
Privacy by Default
Zero personal data collection. Mode A compliance from day one.
- No cookies, no tracking pixels
- Client-side compute only
- Transparent data handling
03
Strict CSP
Content Security Policy enforced with nonce-based scripts.
- No inline scripts or eval
- Rotating nonces via middleware
- Mozilla Observatory A+ rating
Constitution-Driven Development
v2.3.1Every feature traces back to constitutional requirements
