# One-Pass SV-Forms synthetic corpus (Swedish)

**This dataset is entirely synthetic.** It was generated by a script from a concept catalogue, not
collected from anyone. There is no real person in it: names are fictional, e-mail addresses use
`.invalid`, organisations are invented, and the Swedish identifier-shaped values
(`personnummer`, `organisationsnummer`, `bankgiro`, `plusgiro`, `IBAN`) are generated locally with
valid checksums and belong to nobody. It is published so the recipe behind
[`precisit/one-pass-sv-forms`](https://huggingface.co/precisit/one-pass-sv-forms) can be
reproduced and refuted, not because the data has value as data.

## What it is

Training data for a **one-pass option scorer**: a model that receives a context and a supplied list
of candidate decisions and returns one score per option, generating no text. Each line is one
decision:

```json
{"context": "UPPGIFT fyll i formuläret från dokumentet och skicka sedan in\nFORM ...\nELEMENT Edit \"Personnummer\" value=\"\"",
 "options": ["fyll Personnummer: 740721-3466", "fyll E-post: ...", "kryssa", "klicka", "hoppa över"],
 "label": 0,
 "meta": {"action": "fill", "form_signature": "adress|efternamn|fornamn|...", "role": "Edit", "seed": 2026}}
```

- `context` — the task line, the form title and the element in question, plus the entities
  extracted from an attached document. Bytes are what the model sees; there is no tokenizer.
- `options` — the label is an index into this list, so the option order *is* part of the sample.
- `meta.action` — `fill` / `check` / `click` / `skip`, the higher-level decision.
- `meta.form_signature` — the sorted field set of the form the row came from. **The splits are made
  on this value**, so a form's rows never straddle train/validation/test.

## How it was generated

```bash
git clone https://github.com/precisit/one-pass-specialists
cd one-pass-specialists && python -m onepass.synth --output data/sv --episodes 10000 --seed 2026
```

The generator is deterministic given `seed`; `manifest.json` records the episode count, the
ratios, the generator configuration and a SHA-256 per split, so a regeneration can be checked
rather than trusted. This upload was produced by that exact command, and the files here are
gzipped copies of its splits (gzip SHA-256 values are listed below and in `manifest.json`).

| Split | Episodes | Decisions | SHA-256 |
| --- | ---: | ---: | --- |
| train | 7 984 | 234 921 | in `manifest.json` |
| validation | 1 007 | 29 649 | in `manifest.json` |
| test | 1 009 | 29 839 | in `manifest.json` |
| `demo-handwritten.jsonl` | — | 50 | hand-written, not generated: three forms with gold decisions, kept outside the splits as an out-of-distribution check |

Action mix in the training split: `skip` 112 006, `fill` 108 147, `click` 7 984, `check` 6 784 (the
task is deliberately full of "leave this alone" decisions, because that is what a real form is).

## Intended use and limits

- **Use it for:** reproducing the pipeline, learning the input contract, and testing whether a
  small Swedish scorer is the right component for a bounded interface task. It is the "data leg" of
  the recipe in `precisit/one-pass-specialists`.
- **Do not use it as a benchmark of production behaviour.** It is generated from a 50-concept
  catalogue with a fixed set of form templates; real Swedish forms have vocabulary, layouts and
  edge cases it does not contain. The released model's own card states the same limit, and the
  numbers on synthetic held-out rows are not a promise about any real form.
- **Size matters more than it looks.** At 900 episodes the same pipeline and the same schedule
  score 77 % top-1; at 4 000, 98.94 %; at 10 000, 99.29 %. The corpus is published at 10 000
  episodes because that is what trained the released checkpoint, and the smaller configurations are
  one command away if you want the curve for yourself.
- **No personal data, and none may be added.** Keep any real form data out of this repository; the
  value of it is that it is unambiguously synthetic.
