QP09 God Files / Spaghetti Code

What this means

SiteShadow flagged very large, tangled files/modules where many responsibilities are mixed together. These "god files" make it hard to spot security issues and easy to introduce regressions.

Why it matters

Large, tangled files are harder to review, test, and secure.

• Hidden security boundaries: validation/auth checks get lost in noise.
• Higher bug density: changes have unintended side effects.
• Slower remediation because refactoring is risky and time-consuming.

Safer examples

1) Split by responsibility

Separate routing, auth, data access, and business logic into distinct modules.

2) Add tests before refactoring

Lock in behavior, especially for auth and access control, then safely break code apart.

3) Reduce coupling and shared state

Shared globals and cross-module side effects are a common source of security bypasses.

How SiteShadow detects it (high level)

• Uses structural heuristics (file length, number of exports, dependency fan-in/out) as maintainability risk signals.
• Flags oversized modules that tend to hide security boundaries.
