 ## How it's built
 
 Examples were systematically filtered from CommitPackFT to ensure high quality:
 
-- **Scope**: Single-file changes only, excluding binary files, vendor directories, and generated code
-- **Quality**: Removed trivial changes (whitespace-only) and likely test files
-- **Size**: Required 40+ lines in at least one version of the code (old or new); excluded very large files (1000+ lines)
-- **Sampling**:
-    - Target 50/50 split between single-hunk and multi-hunk edits (hunks counted via `@@` markers in the unified diff).
-    - Within each hunk group, stratify by change size (lines added + removed) using the 40th/80th percentiles of that
-      group, targeting ≈40% small, 40% medium, 20% large.
-    - Cap examples to ≤5 per repository per language.
