sdivi-patterns 0.2.47

//! Fixture-level integration test: `testing` bucket population vs. `scope_exclude`.
//!
//! Verifies the design choice documented in `testing.rs`:
//! > `patterns.scope_exclude` removes files from the pattern catalog only
//! > (files remain in the graph). The `testing` bucket is non-empty only
//! > when test files are in the pattern scope.
//!
//! The milestone spec (M42) required: "Integration: a fixture with tests
//! in-scope vs excluded, asserting the bucket populates/empties accordingly."
