Add PDC World Darts Championship simulator with Elo-based bracket (#248) Fixes #123 * Add PDC World Darts Championship simulator (128-player bracket) - New DartsSimulator: 128-player single-elimination, 7 rounds with PDC-accurate best-of-sets formats (bo3/bo5/bo5/bo7/bo7/bo11/bo13). ELO_DIVISOR=500 via set-level Bernoulli model. Two simulation paths: Path A (bracket drawn) simulates from actual DB matches; Path B (pre-bracket) seeds top 32 by world ranking in fixed positions and randomly draws the remaining 96 per simulation run (50,000 iterations). - darts_bracket added to simulatorTypeEnum and simulator registry. - world_ranking nullable integer column added to participant_expected_values (migration 0067); batchSaveSourceElos now accepts and persists it. - Admin route /admin/sports-seasons/:id/darts-elo: bulk import with format "Player Name, 2099, 1" (name, Elo, optional world ranking), fuzzy name matching, auto-runs simulation and updates EV/snapshots on save. - DARTS_128 bracket template added (scoring starts at Quarterfinals). - 30 unit tests: math helpers, bracket seeding structure, Path A/B integration. https://claude.ai/code/session_01WZ6FjMmC2eBeZ1564M9Ruz * Review fixes: pre-compute hot-loop invariants, import normalizeName - Pre-compute seededSlots and getSeededMatchOrder(32) before the 50k simulation loop — was being recomputed every iteration - Pad unseeded pool to 96 once before the loop instead of inside it - Inline bracket-building in the hot loop using pre-computed seededSlots; removes the per-iteration call to buildR1Bracket/getSeededMatchOrder - Remove dead SEEDED_R1_PAIRS constant (was never referenced) - Import normalizeName from ~/lib/fuzzy-match instead of redefining it locally https://claude.ai/code/session_01WZ6FjMmC2eBeZ1564M9Ruz * Fix lint failures: unused vars, eqeqeq, toSorted - Remove unused seededSet/unseededSet variables in test - Replace != null with !== null && !== undefined (eqeqeq rule) - Replace .sort() with .toSorted() in simulator and route (unicorn/no-array-sort) https://claude.ai/code/session_01WZ6FjMmC2eBeZ1564M9Ruz * Fix TS2552: restore seededSet declaration removed during lint fix https://claude.ai/code/session_01WZ6FjMmC2eBeZ1564M9Ruz --------- Co-authored-by: Claude <noreply@anthropic.com> 2026-03-31 15:37:28 -07:00			`ALTER TYPE "public"."simulator_type" ADD VALUE 'darts_bracket';--> statement-breakpoint`
