Codex and other coding subagents have been creating branches like
experiments/foo and feature/bar without being asked. This fragments
review, hides work from the user, and requires manual cleanup. The
project intentionally develops on main with frequent small commits.
AGENTS.md adds an explicit "Git Branching Policy" section: no
checkout -b, switch -c, branch <name>, or PR-from-new-branch unless
the user asks for it in the current task. Includes a pass-through
clause so this propagates to subagents the main agent spawns.
CLAUDE.md adds a one-line pointer with the same pass-through note,
since CLAUDE.md mandates AGENTS.md is read at session start.

The avg-strategy 1000iter file (with the recent +traversals/+LR/+LCFR
changes) is the canonical "best-known" config. Renamed it to
default.yaml so users start from a single, obvious entry point and
override one field per ablation via --set. Other 12 configs moved to
configs/archive/ — kept for historical reproduction, not for active use.
- configs/deep_cfr/{default.yaml, smoke.yaml} are the only active configs
- experiment_name shortened to "deep-cfr-default" (was a long mouthful)
- AGENTS.md examples and Project Layout section rewritten around
default.yaml; ablation example shows the override-one-field pattern
- Tests pointed at the archived slot-playability config for the legacy
reproduction assertions

Default is one baseline + one treatment, sequential, same seed, with a
shared --wandb-tag hypothesis label for W&B Compare Runs filtering.
Multi-seed only on explicit request; never run two trainings on the same
GPU.

Brief guidance on roles (notes = purpose, tags = filter categories)
plus three anti-patterns to avoid. Otherwise free-form.

- AGENTS.md: add Weights & Biases section covering install (extra),
online/offline modes, per-run wandb/ layout, sync command, and the
source-of-truth note (metrics.jsonl, not W&B).
- CLAUDE.md: replace soft "before making changes" wording with a
mandatory session-start instruction to read AGENTS.md in full.

Drop checkpoint.directory from config — config defines what an experiment
is, not where its outputs go. The CLI now computes the run directory from
run.experiment_name plus a timestamp, defaulting to runs/tmp/ for
throwaway runs and runs/ when --keep is passed.
- Remove CheckpointConfig.directory and DeepCFRConfig.checkpoint_path
- DeepCFRTrainer takes run_dir: Path explicitly
- CLI: add --keep boolean; --resume requires an explicit path (no shortcut)
- Auto path: runs/[tmp/]<YYYY-MM-DD_HHMMSS>_<experiment_name-kebab>/
- Rename 13 configs to kebab-case; strip directory: lines; kebab their
experiment_name values
- Rewrite AGENTS.md training/run sections; document
archive/tmp/<flat> layout, --keep, kebab-case scope
- Update tests for new run_dir flow and dropped --resume shortcut

Remove legacy aliases, rename max_hours to max_minutes, collapse the
four checkpoint save flags into save_every + save_latest, and change
defaults to safer values (opponent_policy=self_play_league,
device=auto, eval_every=50, max_depth=null). Migrate all archived
yaml configs and tests to the new schema.
