# Data provenance: CodeMixCheck v2.2.1

## Provenance classes

| `provenance_class` | meaning | rows in v2.2.1 project corpus | in this release |
|---|---|---|---|
| `template_generated` | produced by the dataset author's template pipeline; templates and entity pools written by the author with Claude / ChatGPT as writing helpers (tool not recorded per row) | 6,917 | 6,910 (7 held back, see G06) |
| `llm_assisted_human_curated` | claims selected by the author from news and reference material and rephrased in his own Tanglish wording, with LLM help | 344 | 344 |
| `social_media_derived_third_party_human_authored` | comments written by third parties on public Instagram posts and collected manually | 341 | 0 (not released) |

How these map to common provenance categories:

| category | in this release? | where |
|---|---|---|
| original human-authored third-party content | no | not released |
| human-paraphrased content | yes | `test_curated`: author-rephrased claims |
| AI-assisted content | yes. LLM help went into templates and curated claims, but this is not separable per row | all configs |
| template-generated content | yes | train / validation / test_synthetic, sentiment, abuse |
| news- / reference-derived content | yes, as paraphrased claims (no article text) | `test_curated` |
| social-media-derived content | no | not released |

## Attestation

The dataset author (Prajjit Basu) states that:
- he created the templates, entity pools and generated records himself, using Claude and ChatGPT as writing helpers;
- no text was copied from articles, websites or other datasets;
- the `@` handles in synthetic text are invented placeholders;
- he selected the 344 curated claims himself and rephrased them in his own wording where needed.

A release audit supports the curated-claim statement: no curated row contains more than 8 consecutive common-English words, and the texts read as short generic claims rather than article sentences.

## Missing provenance (not filled in)

- `source_reference = not_recorded` for curated rows. The specific articles and the reference document behind `tang_pdf_facts` were not recorded. **No URLs, publishers, dates or citations have been invented.**
- `generator = not_recorded`. Which assistant helped with which batch was not logged.
- 782 IDs were retired before v2.1, and no per-row reasons survive.
