A read-only drift detector compares your code against the specification file SPEC.md. It finds places where the code has changed but the spec hasn't or vice versa. The results are grouped by severity so you can see what is most urgent.
The tool never writes anything. It only reports violations and gives hints for fixing them. You decide whether to fix the code or update the spec. This helps you catch drift early before it causes bigger problems.
Use it after each build and before each release. It checks invariants, interfaces, and task status. Each item is binary: it holds or it drifts. No scores, just clear findings.
