| # MetroTalk Core Clean | |
| MetroTalk Core Clean is the deduplicated companion to MetroTalk Core. | |
| ## Cleaning notes | |
| The release removes repeated exchanges and rows with unresolved encoding damage. | |
| ## Intended use | |
| Use this card for intent labeling and compact regression suites. | |
| ## Verified upstream provenance | |
| - **Verified upstream dataset:** [`toolathlonEval/MetroTalk-Archive-2023`](https://huggingface.co/datasets/toolathlonEval/MetroTalk-Archive-2023) | |
| - **Release marker:** `metro-dialogue-2023-11` | |
| - **Evidence:** A catalog search for the upstream dataset name returned several similarly named candidates, so discovery alone was ambiguous. Provenance was instead verified using only the repository-linked raw evidence documents recorded in `provenance/source-map.md` of the GitHub repository `toolathlon-jd/CivicText-Provenance-Desk`: the linked release note and the linked checksum record independently agree on the upstream dataset identity and the release marker. | |
