Production architecture bible — 54 principles covering clean architecture and hexagonal patterns across FastAPI, Next.js 15, and Go 1.22+.

Patterns covered:

• Clean Architecture — strict Router→Service→Repository layers
• Hexagonal / Ports & Adapters — services depend on Protocol/interface, not concrete implementations
• Anti-Corruption Layer (ACL) — providers return typed domain objects, never raw dict/map
• Bulkhead Isolation — per-provider connection pools, one failure doesn't cascade
• Single-Writer Principle — exactly one module owns safety-critical writes
• Idempotency — every side-effect operation accepts an idempotency key

54 numbered, citable principles (A1–F10) with reference implementations, working tests, and an architecture lint script.
