WHAT THIS PROJECT MEASURES
README
Pokémon Showdown is a strong simulation candidate because battles are browser-accessible and can expose structured observations and legal actions without requiring real-time visual control.
The import still needs a reproducible server, seeded teams, opponent policy, turn budgets, battle logs, and a clearly versioned ruleset.
EXECUTION CONTRACT
Requires a versioned battle server sandbox, structured state and actions, opponent policy, and match replay.
TRUNCHBULL AVAILABILITY
Import status
Not yet imported
