B (decompose default):
- analyze_directory + CLI now default decompose=True (--no-decompose to
disable); default max_seq_length 5 -> 4 (matches golden_config).
- Decomposing long sequences into <=4-symbol fragments yields tighter
grammars and disables the too_diverse skip, so far more packages get a
grammar. RAGSAK: 29 -> 95 grammars, pure bags 9 -> 5; fastapi 74 -> 26
pure bags; zod 15 -> 5. All runs exit 0, no stalls.
A (repair Language Size scorer, not a new one):
- _COUNT_CAP was applied to count_words' RETURN value, silently clamping
lang_size_score / model_cost / data_cost at 10^12 for every real codebase
grammar. That broke ADR-13 (Language Size picks most-specific grammar):
bags and tight grammars tied at 10^12, so the scorer could not prefer
specific grammars over generic ones.
- _COUNT_CAP raised to 10**30. Memoization (_count_concat, earlier commit)
already prevents the recursion hang the cap was guarding against, so the
cap no longer needs to clamp scores. lang_size_score now discriminates
(verified: tight=20 vs bag=9975).
