# Complete FABLE.5 Traces 2M
<strong>Full FABLE.5 / Mythos corpus restored, with session-limit answer rows removed.</strong>
[`Dataset Viewer`](https://huggingface.co/datasets/Crownelius/Complete-FABLE.5-traces-2M/viewer/default/train) | [`Parquet`](data/train.parquet) | [`Raw JSONL.gz`](raw/fable5_mythos_dedup.jsonl.gz)
</div>
This dataset is a post-closure compilation of all available FABLE.5 / Mythos trace datasets found on Hugging Face during the curation pass after the closure of Fable and Mythos. It is deduplicated at the normalized-row level and keeps row-level provenance through `first_source_dataset`, `first_source_config`, `first_source_split`, and `first_source_row_index`.

## What Changed
The full corpus export has been restored. Rows containing the session-limit assistant-answer pattern were removed from both downloadable files:
| File | Rows | Purpose |
| --- | ---: | --- |
| `data/train.parquet` | 2,006,487 | Viewer-friendly canonical Parquet split. |
| `raw/fable5_mythos_dedup.jsonl.gz` | 2,006,487 | Gzip-compressed canonical JSONL mirror of the Parquet schema with provenance fields plus original row JSON. |
The Parquet file is smaller because it is compressed columnar storage. The raw JSONL is gzip-compressed so the repository keeps the complete raw export without exposing sparse event fields as top-level blanks or storing redundant uncompressed text.
The repository is intentionally compact:
- `README.md`
- `data/train.parquet`
- `raw/fable5_mythos_dedup.jsonl.gz`
## Schema
| Column | Type | Description |
| --- | --- | --- |
| `row_hash` | string | SHA256 of the normalized original row JSON. |
| `first_source_dataset` | string | First dataset where this canonical row was observed. |
| `first_source_config` | string | First observed config or loader surface. |
| `first_source_split` | string | First observed split, file, or local extraction label. |
| `first_source_row_index` | int64 | Row index within the first observed source surface. |
| `seen_count` | int64 | Number of times this canonical row was seen during the pass. |
| `row_json` | string | Preserved original row as canonical JSON. Parse this for source-specific fields. |
## Source Citations
Every row can be traced back to the dataset where that canonical row was first observed. For rows with `seen_count` greater than `1`, the same canonical row appeared more than once during curation; the preserved `first_source_*` fields identify the citation source used for that row.
