Four new verb engines, each 100% against a single kaikki/UniMorph oracle
(Beta tier), taking the live count 59 → 63:
- Esperanto (epo): pure suffixation off the -i stem, zero irregulars.
139,993/139,993 forms, 2,891 lemmas, 100% rule-derived.
- Scottish Gaelic (gla): broad/slender synthetic core (future/past/
conditional/imperative/relative/passive), lenition normalisation, ~10
suppletives mined; no synthetic present (periphrastic, out of scope).
5,396/5,396 forms, 794 lemmas.
- Guaraní (grn): areal/aireal/stative classes + nasal harmony read from
the kaikki gug-conj template names; 5 voices. 4,964/4,964 forms, 68
lemmas, ~99.75% rule-derived (16 soro coactive overrides).
- Hawaiian (haw): derivational engine — hoʻo- causative (onset-driven
allomorphy), full reduplication, -ʻia passive — verified against kaikki
lemma-linked derived terms. Periphrastic TAM (ua/ke…nei/e…ana) is
syntax, out of scope. 316/316 forms, 252 lemmas, 94.9% rule-derived.
Navajo (nav): parked (docs/nav/oracles.md). A measured build attempt found
only 13.9% of forms rule-derivable from UniMorph's surface data — templatic
position-class polysynthesis with cross-slot morphophonemic fusion is a
different architecture (Athabaskan FST + segmented lexicon) than ablaut's
principal-parts-plus-rules model. High Valyrian/Klingon (constructed) skipped.
Registration: Lang::{Epo,Gla,Grn,Haw} at ordinals 59–62, reverse.rs arrays
→63, from_code aliases, Conjugation variants + build dispatch, PyO3 + wasm,
Cargo includes, correctness.py NAMES, CI golden gates. Verified in main:
4 gates 100%, 376 lib tests, clippy -D warnings clean, fmt clean, wasm +
python features compile.

Version bump for the four new Beta engines (Esperanto, Scottish Gaelic, Guaraní, Hawaiian) landing in #159 — live engine count 59 → 63. Minor bump per new-language additions. pyproject inherits the version from Cargo (dynamic); pkg/pkg-node versions are set at wasm build time.
