| 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.) | |
