## Summary
- **Bug fix**: EPL Elo/odds fallback was gated on \`dbEloMap.size === 0\` — if any team had a direct \`sourceElo\`, teams with only \`sourceOdds\` were never populated and the simulator threw "Missing Elo" instead of using their odds data
- **Iterations**: WorldCupSimulator default 50k→10k; manifest \`defaultConfig\` for \`world_cup\` and \`epl_standings\` now explicitly override \`BASE_CONFIG\` with 10k so the production fallback matches; test iterations reduced (WorldCup 500→100, EPL 10k→500) to fix timeout failures on slower CI
- **Cleanup**: Extracted \`runKnockoutRound\` out of the 10k-iteration simulation loop; replaced two hot-loop \`toSorted()\` calls on 2-element arrays with a conditional string comparison; removed local \`normalizeProbabilities\` in favour of the shared \`normalizeSimulationResultColumns\`
## Test plan
- [ ] \`npm run test:run\` — all simulator unit tests pass without timeout
- [ ] Typecheck passes (\`npm run typecheck\`)
- [ ] EPL simulate with mixed Elo+odds data no longer throws
