Third-party evaluation
The AI Accountability Lab scores published summaries against the Commission's template and publishes the result. These are captures of their assessment, archived here because they are revised over time and a score is otherwise unrecoverable once changed. It is AIAL's research judgement, not a legal determination, and not the provider's document. Their assessment is archived here but not served on this site or in the dataset: each capture below proves what was published and when, and points to AIAL for the content. Attribution: aial.ie.

Captures of superseded target URLs
Locations this ledger previously tracked for this source (per-row notes give the reason each was superseded) — kept as faithful records of what those URLs served at capture time.

The pre-rename path is a leftover directory in their repository: their site writes one directory per evaluation file, and no file carries the old name any more. |
