feat: frequency threshold sweep — 0.01-0.20 across 4 codebases
...
Sweet spot: 0.01-0.05. At 0.01 RAGSAK gets 61 SOREs (26.1% cov) with
real conventions like warn.status.body.ErrorResponse. At 0.05 coverage
jumps to 45.4% but that pattern disappears. Flask dies at 0.15+.
Current default min_coverage=0.2 is too aggressive for most codebases.

feat: 4-codebase evaluation — conventions vs completions tradeoff
...
Added kotlinx.coroutines (1040 .kt files) and FastAPI (1129 .py files).
Key findings across 4 codebases:
- Coarsening trades per-package coverage for cross-package reach
- FastAPI: coverage IMPROVES (12.4% -> 20.7%), cross-pkg +15
- Coroutines: cross-pkg +15, real exception-handling patterns
- RAGSAK: cross-pkg +18, null-check conventions across 8 packages
- Flask: slight cross-pkg loss, rendering conventions still visible
The conventions vs completions tradeoff is real and measurable.

feat: structural coarsening experiment — keeps function names raw, coarsens keywords
...
- coarsen_token() maps tree-sitter captures to categories (RETURN, IF, LOOP, etc.)
- Function calls kept as raw text (they ARE the behavioral content)
- Only ~5% structural tokens coarsened
- Results: Flask coverage 17.5% -> 28.8% (+11.3%), RAGSAK unchanged (95% calls)
- Cross-package shapes emerge: ('IF', 'KW', 'RETURN') in 4 Flask packages

...
- Full experiment history: context strategies, Reduce, scoring, GBNF, cross-package
- Documented failures: per-package sparsity, Reduce at wrong level, exact match rarity
- Designed next experiment: structural coarsening via tree-sitter categories
- Updated RESULTS.md with Round 5 findings and summary table
