| # verdigris-d2d8b9d2 |
|
|
| Cleaned SFT corpus for Bittensor **SN120 (Affine)**, Reason v4 |
| (`weight_version_key=7`). 17,655 rows, TRL prompt-completion format. |
|
|
| Format is exactly `</think> |
| THOUGHT: {z} |
|
|
| {y}` on every row. |
|
|
| ## How it was cleaned |
|
|
| Derived from [`iamPi/tessera-77d11909`](https://huggingface.co/datasets/iamPi/tessera-77d11909). |
| Prompts and actions are byte-identical to the source; only the thought |
| channel changed, and 483 rows (2.66%) were removed. |
|
|
| ### Repaired in place (40.08% of rows had at least one defect) |
|
|
| | defect | rows | |
| |---|---| |
| | stray `<think>` / `</think>` / `<thinking>` / `</thinking>` in the thought | 7,124 | |
| | corrupted THOUGHT label (`THO`, `THOTH:`, `THOFTWARE:`, `THOTHought:`, `THOURLY Thought:`, `THOproperly` …) | 218 | |
| | duplicated leading `THOUGHT:` / `THOUGHT` | 188 | |
| | a second THOUGHT label mid-thought | 72 | |
| | in-thought ` ```bash ` fence retagged to ` ```sh ` | 114 | |
|
|
| The retag matters: the validator's `BASH_RE` matches only ` ```bash `, and |
| `split_rollout` takes the **last** match as the action. A thought that quotes |
| a bash fence could therefore be mistaken for the command whenever a model's |
| real fence came out malformed. |
|
|
| ### Removed (483 rows) |
|
|
| | reason | rows | |
| |---|---| |
| | thought shorter than the 80-char crown floor | 444 | |
| | completion longer than the 1,792-token rollout budget | 34 | |
| | harness output (`<returncode>` / `<output>`) leaked into the thought | 5 | |
|
|
| Those last five were collapsed multi-turn transcripts: the "thought" |
| contained the result of a command that had not been run yet, which would |
| train the model to hallucinate observations. |
|
|
| Two-channel thoughts — latent analysis followed by a visible summary — were |
| **kept**. That is the contract's own shape: `split_rollout` joins the latent |
| and visible halves on purpose, and 57 of the 61 such rows carry genuinely |
| distinct text in each half. |
|
|
| ## Guarantees |
|
|
| Every row was checked after rewriting: it round-trips through the validator's |
| own `split_rollout`, is byte-identical to the `force_text()` rendering, has no |
| think tag / THOUGHT label / bash fence / harness tag in its thought, clears |
| the 80-char floor, and fits the rollout budget. |
|
|
| ## Variants |
|
|
| A cue-appended build with an identical row set exists for A/B testing. |
