# Legacy research stacks

The supported project path is the JAX rules engine and JAX PPO tooling exposed
by `lost-cities-jax-ppo`. The historical Deep CFR and ISMCTS implementations
are preserved for research reproduction, but they are not current training
recipes and no longer have public console-script entry points.

## What is preserved

- Deep CFR sources: `src/coolrl_lost_cities/games/classic/deep_cfr/`
- ISMCTS sources: `src/coolrl_lost_cities/games/classic/ismcts/`
- Their retired configurations: `legacy/deep-cfr/configs/` and
  `legacy/ismcts/configs/`
- Earlier plans and dated findings: `docs/plans/archive/`, `docs/archive/`,
  and `docs/research/`

These files remain in the repository so a historical experiment can be read or
reproduced against its original commit. They should not be chosen for new
models, benchmarks, or product work.

## Current workflow

Start from `configs/jax_ppo/`, run `lost-cities-jax-ppo`, and use the browser
client in `web/`. The root [README](../README.md) contains the short training,
evaluation, and static-web recipes.
