# Data directory

All intermediate data and outputs are written here by the pipeline.

Subdirectories (auto-created):

- `models/`         — Hugging Face weights (Qwen3-30B-A3B-Thinking-2507)
- `cots/`           — Generated CoTs + test problem lists
- `routing/`        — Sharded router dumps from Stage 1
- `activations/`    — Decision-point residual stream tensors
- `checkpoints/`    — Direction vectors, top-expert lists
- `logs/`           — Per-script log files
- `results/`        — Final outputs (plots, JSON, report)

To override the default location, set env:
    export DATA_ROOT=/some/other/path

To start fresh:
    rm -rf data/routing data/activations data/checkpoints data/results data/logs

(Do NOT delete `models/` unless you want to re-download ~60GB.)
