- tools/extract_all.py: recursive extraction of all archives (incl.
nested) into a plain-file tree; nested archives are deleted after
successful extraction, plain files are hardlinked, failures go to
.broken/, extract_manifest.jsonl records archive->dest->unit.
- sorter --provenance: classify each extraction directory once under
the archive's name (files of one archive are one unit; inner
structure kept), so loose STLs sort with their model set.
- matching discipline: a fuzzy match never leaves the file's system;
system-less files need CROSS_SYSTEM_MIN (0.75) for a catalog unit,
and a same-system faction jump below 0.75 is rejected. Fixes 40k
files landing in Middle-earth/Blood Bowl/AoS buckets.
- speed for big trees: lru_cache on keyword matchers and pair scores,
quick_ratio pruning; keywords: night lord, csm.
