# 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.
