User corrected: papers that use AI but DON'T clearly document which model or how it was used are EXACTLY the kind of papers this study needs. The vague AI acknowledgment pattern (scoring 0 on A1 Model Named) is itself the phenomenon the TRACE paper studies. Inclusion criteria should be: if the paper appears to use AI/LLM as a tool in environmental science, include it even if the specific model isn't named - the poor documentation is a data point, not an exclusion reason. This reframes the screening: the question is 'did they use AI for env sci?' not 'can I confirm they used an LLM specifically?'",

Case is kept where it carries meaning (Mt is megatonnes, kt is kilotonnes, Gt is gigatonnes); case is ignored only in spelled-out words (\"Metric Tons\", \"Million\", \"tonnes\"). [...]\nRationale: Lowercasing was there so that formatting differences (\"Tonnes\" against \"tonnes\") would not count as wrong answers, a problem the toy runs ran into. For units, though, case is part of the meaning: in standard SI prefixes, M is mega and m is milli. Folding case makes megatonnes and metric tons look alike, so magnitude errors can neither be caught nor counted. [...]\nHuman accepted: Operator: \"i accept this revision. implement this.\"",

No absolute cosine cutoff separates relevant from irrelevant for any model (best reachable F1 0.10 to 0.16), and random-pair baselines differ by model (0.21 to 0.68), so a per-provider constant would still be wrong on realistic queries.

Dropping the parent produces a record that reports itself complete while omitting lineage the log states, which is exactly the fail-open behaviour removed from the producer in pull request #19 for unrecognised snapshot directories; reintroducing the same class of silent omission one day later, in the lineage the record exists to carry, would undercut the fail-loud discipline the repository is built on.
