Scottish Gaelic stemmer benchmarks
Benchmark-only dictionary — not distributed
gd-gb-default is privately retained for reproducible measurement only. Radixor does not distribute, install, publish, register, or support this dictionary because file-applicable redistribution rights are unresolved. It has no Maven coordinates, BOM/catalog entry, standard-package membership, or Python package.
Evidence: Selected data file lacks file-applicable license evidence. Benchmarking these private bytes does not assert a right to redistribute them.
Dictionary size: . The exact count is 265 distinct usable word forms after parser-compatible filtering and exact case-preserved deduplication. Stars rank size among all 167 benchmarked dictionaries; they do not measure linguistic quality, availability, or benchmark accuracy.
The corpus, quality, generalization, and speed evidence below belongs to the private 2026-09-11 Radixor/Java 4.4.0 documentation snapshot. It is never placed on a production or release classpath.

Pairwise linguistic quality
OI and UI report over-stemming and under-stemming with raw numerators and denominators. A zero denominator is n/a.

Dictionary-family generalization
This frozen five-seed curve measures transfer to withheld lexical families; it does not establish redistribution or support status.

Runtime timing
JMH average time uses 3 one-second warmup iterations, 5 one-second measurement iterations, 3 independent forks, and 1 thread.
