The targeted test only covered the RBY side (ItemEffects.lua,
TrainerAI.lua); src/battle/gen2/Battle.lua's EFFECT_LIGHT_SCREEN/
EFFECT_REFLECT fix had no test at all, spotted when asked whether the
Gold changes were covered.
Adds a minimal MACHOP/TACKLE gen2 fixture (same shape as
tests/gen2_move_effects_test.lua's), calls both MOVE_EFFECTS directly,
and checks a loaded catalog reaches the whole message template (Gold
wraps the full sentence, not just the stat name). Confirmed it catches
the regression: reverting Battle.lua to its pre-fix state fails 2 of
the suite's now 8 checks.
No existing test could tell a translated stat name apart from a raw
stat:upper() that never went through Strings() at all: every rose!
message assertion in the suite runs with no catalog loaded, where
Strings() is an identity function either way.
Loads a real catalog (Strings.load) that translates one stat name at a
time and checks it actually reaches the X-item, vitamin, and AI-trainer
X-item messages -- ROM-free, over tests/fixture_data. Confirmed this
catches the regression: reverting src/inventory/ItemEffects.lua and
src/battle/TrainerAI.lua to their pre-fix state fails 5 of 6 checks.
