# When an agent follows the repository ids, version names and sample counts printed in the 1X cards and README, which of them have drifted (renamed ids, v1.1 vs v2.0, 450 vs 250 test samples) and what must be pinned?

At observation, the ids printed in the cards (1x-technologies/worldmodel and worldmodel_raw_data) answer with HTTP 307 to world_model_tokenized_data and world_model_raw_data, so a pin should use the sha, not the name. The GENIE cards and the README leaderboard refer to challenge v1.1 and data/val_v1.1, while the tokenised-data repository (sha 42e3e12f..., lastModified 2025-04-20) describes v2.0 as replacing v1.1 and still lists the v1.1 folders. The two dataset cards give different test-set sizes (450 vs 250 samples). These are observations of text and listings, not a history of changes.

Curator qualifications: Card counts disagree (450 vs 250); printed ids redirect to renamed repos; pin by repo sha.
