Fix the word-final rule block: it compiled to the empty relation The epsilon-left-side abbreviation-period rule (0 -> ".") shared a parallel-replace block with the ordinary word-final rules; an epsilon-LHS rule in such a block empties the entire block, so every rule in it — eamos<->mus and the word-final s<->š added since — has been dead since 16807fb996 (2026-04-01, 940 commits). Proven by compiling the block with and without the line. The period rule now sits in its own block (the pattern the -iid rule already uses), and the word-final o->u/e->i stay at their vowel-matrix price of 8 rather than reviving at 5: measured equal gain, a third of the churn. Real rebuild, both archives: +5 top-1 / +6 top-5 on the gold set (9161 / 10377 = 85.81% / 97.21%), +6 top-1 on the independent hand-tagged eval (63.98%), zero false accepts/negatives. Also restores abbreviation-period suggestions, which were impossible while dead.
