jedarden	d43cf83471	feat(evolver): island cross-pollination every 50 generations per §10.2 ... Adds cross-pollination logic that copies the top program from each island to a random other island every 50 generations. When source and target islands use different languages, the LLM translates the code. Generation boundaries are tracked per-island to prevent duplicate events. - New crosspoll package with boundary detection, migration, and LLM translation - Added MaxGenerationByIsland DB query for generation counter tracking - Integrated into RunEvolutionLoop with observability logging - Tests for boundary logic, translation prompts, and target selection Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-04-22 15:13:27 -04:00
jedarden	4ba39e3aa8	feat(evolver): complete Phase 7 LLM-driven evolution implementation ... - Complete autonomous evolution pipeline with island model (4 islands) - MAP-Elites behavior grid integration for diversity - LLM ensemble integration (fast + strong model tiers) - 3-stage validation pipeline (syntax → schema → sandbox smoke test) - Evaluation arena (10-match mini-tournament per candidate) - Promotion gate (Nash equilibrium PSRO + MAP-Elites niche fill) - Retirement policy (auto-retire low-rated bots, population cap) - Live export to R2 for evolution dashboard - Enhanced replay viewer with commentary and win probability - Added series, seasons, and predictions pages All tests passing. Phase 7 exit criteria met. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-04-08 16:38:48 -04:00
