Software Engineering Philosophy & Development Protocol

1. Global Integrity & Topology

• System Awareness: Before implementation, map the dependency graph and system topology. Ensure local changes preserve global invariants and do not trigger "Shotgun Surgery."
• Orthogonality: Design for independence. Ensure that changes in one module do not leak side effects into others. Minimize coupling and maximize cohesion.

2. Intent & Abstraction Hierarchy

• Intent-Revealing Design: Prioritize human readability and intent over machine cleverness. Use naming that explains "Why" rather than "How."
• Single Level of Abstraction (SLA): Adhere strictly to the Single Responsibility Principle (SRP). Each function must operate at a consistent level of abstraction and have exactly one reason to change.
