Provenance
Every row carries Tülu-style lineage:
content_hash— sha256 over (system, user, assistant, site, is_noop, sha256(image bytes)); stable content identity (oversampled duplicate rows share it).source—<collection>/<site>, collection ∈ {webarena, liveweb}, inferred per trajectory (a trajectory touching the WebArena instance host iswebarena).
Decontamination (report-only; no rows removed)
Checked at revision 6c6f8ad64fa67bf08353e7de703a42ec22636f5a: 8-gram word overlap of train prompts vs val_in/val_out prompts (GOAL/CURRENT URL/ACTION lines only), plus val_out site- and goal-template-identity (docs/plan/05-evals.md).
- removal rate (flagged, not removed): 9.9% (47/476 train rows)
- breakdown: ngram∩val_in 22, ngram∩val_out 6, exact prompt 0, val_out site 0, val_out template family 25
- trajectories straddling train/val_out (site-wise split cuts multi-site trajectories row-wise): 5
Changelog

4ea38deac64c3932e0fedc5eb4111b78814d1bec): decontamination removal per PR #12 review sign-off — drop the 5 train/val_out-straddling trajectories' rows from val_out (48 → 33). train and val_in unchanged.
