● v3.8 Changelog

1. Commands.kt Full Bilingual (~112 strings)

• All 22 command handler functions now support English via Lang.t()
• Labels: Species, Level, Friendship, Weather, Ability, Types, Status
• Relationship types: BEST FRIENDS, FRIENDS, ACQUAINTANCES, NEUTRAL, DISLIKE, RIVALS
• Time of day: Morning, Day, Sunset, Night, Dawn
• Weather: Storm, Rain, Clear
• All help text, error messages, admin commands, friendship bonuses, battle sync, world context

2. RL Action Key Fix (CRITICAL BUG)

• trackAction() was storing literal string "response" as action key since v2.4
• All policies had only 1 action entry → RL scoring in SRG used part.take(40).lowercase() as lookup key → never matched "response" → getActionSuccessProbability() always returned default 0.5f
• The entire RL scoring boost was non-functional since inception
• Fix: now stores finalResponse.take(40).lowercase() as action key, matching what scoring looks up

3. RL-Driven Response Generation (NEW)

• New generation path using chooseBestAction() to produce response parts from learned policies
• Guards: 30+ episodes (no cold start), action 5-150 chars, not old "response" key, success probability > 60%, budget-gated at 15%
• Tracked as "rl_response" feature source for feedback loop

4. Context Quality Threshold Lowered

• SRG threshold: 0.5f → 0.35f (0.5 was blocking learning context for new/young Pokemon)
• LCI: added enhancementScale — at quality 0.35 → 30% enhancement strength, at 0.5+ → 100%
• New Pokemon now benefit from learning data much earlier

5. LanguageGrowth Catchphrase Getter

• Added public getCatchphrase(pokemonId): String? method
• Catchphrases were already used internally in enrichResponse() at 5% chance, but now accessible externally

6. ExternalAI Diversity Penalty Fix

• Old: sqrt(excess) * 0.03 subtracted — response used 100 times still had ~70% quality
• New: ln(1 + excess) * 0.06 multiplicative — 10 excess: ×0.86, 50: ×0.76, 100: ×0.72, 500: ×0.63
• Floor at 5% prevents total data loss

7. TPS Optimizations

• Cache TTL: CACHE_TTL_TICKS 10 → 40 (0.5s → 2s) — event-based invalidation handles fast updates, TTL is just a fallback
• GlobalKN flatMap: flatMap { listOf() + list }.toSet() → mutableSetOf() + forEach { addAll } — eliminates intermediate List allocation
• GlobalKN eviction: sorts lightweight Pair<String, Float> instead of full Map.Entry objects
