ripvec-core 4.1.15

//! Integration tests for the per-language entry-point detector
//! (4.1.0 Front X1).
//!
//! Each test feeds a synthetic source snippet to the language's detector
//! and asserts the kind + name of the emitted [`EntryPoint`]s. The tests
//! are written against the shape promised by
//! `docs/FIND_DEAD_CODE_DESIGN.md` Section 2; a future X2 will consume
//! the same contract from the dead-code analysis pass.
