10. Quality Requirements

10.1 Quality Tree

Quality Goal	Scenario	Measure
Correctness	Given valid input, output matches the expected minesweeper format exactly.	All kata test cases pass.
Simplicity	A new developer can understand the full codebase in under 10 minutes.	Three focused components, no external dependencies.
Testability	Each component can be tested without running the full application.	Parser, processor, and formatter accept stream/struct arguments directly.
Portability	The binary compiles and runs on Linux, macOS, and Windows.	Standard C++17, no platform-specific APIs.
