A1 — Principle-Driven Design Review

Task

Select a non-trivial module (roughly 500–3000 LOC, or an equivalent design slice). Produce a technical design review based on explicit principles.

Required analysis

• module responsibilities and likely reasons for change;
• dependency graph;
• information-hiding assessment;
• cohesion/coupling observations;
• at least two SOLID/GRASP/component-principle arguments;
• three change scenarios;
• two alternative redesigns;
• final recommendation with trade-offs.

Constraint

Do not score the design by counting principle “violations.” The goal is to explain consequences under concrete changes.
