Module clones 

Clone detection.

Identifies Type 1 (exact) and Type 2 (renamed/parameterized) clones via AST structural hashing on tree-sitter parses. The fingerprint walks the AST in pre-order emitting (kind_name, child_count) pairs while skipping identifier, literal, and comment nodes — this normalization is what makes the hash Type 2-aware.

Optional Type 3 (near-miss) support via MinHash + LSH is not yet implemented.

The clone-coupling intersection — clone families that ALSO co-change at Fisher-significant rates — is the differentiating signal CodeScene calls “X-Ray”, with our published-formula transparency wedge applied.
