Each CPU now thinks with one of four engines, each backed by a different published library (pinned versions): - montecarlo (@pokertools/evaluator): the existing balanced Monte Carlo equity player, moved to server/bots/montecarlo.js. - calculator (poker-calculations): the library's decideAction over the table state; push/fold below 12BB via its jam breakeven equity. Skipped automatically if the native addon cannot load. - range (poker-utils): tight player; preflop by hand-strength percentile, postflop equity vs an estimated opponent range, bluffs only when alpha/bluffEV say they pay. - madehand (pokersolver): loose, sticky player that only looks at the made hand and draws. server/ai.js assigns a mix of engines per table (makeStyles), falls back to the Monte Carlo engine on errors, and legalizes every decision. The engine and its parameters stay server-side; players cannot tell which library a CPU uses. Tests cover every engine and the no-leak rule. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
