The skip list now matches `license`, `licence`, `copying` only with no extension or md/txt/rst, so src/license.rs and Copying.cs stay indexed. CHUNKER_VERSION is back to 1: a bump rebuilds the live collection; the already-indexed noise paths go by a one-time delete_by sweep instead (work/sweep/sweep-sources-noise.py, same rule).
