What Language Is the Reward Written In? Data package (queries, codebooks, coded data)

Data package for the paper What Language Is the Reward Written In? Language Reporting Practices in LLM Reward Design (ICIDSMAI 2026, Springer LNNS). It contains the dated arXiv query strings with their result counts, the codebooks used for coding (in French, as written before coding), and the coded data behind the paper's figures: the 50 coded reward-design works, the two model codings of the 20-work reliability subsample, the domain codings, and the recall sample of the lexical screen. A README maps each file to the section of the paper it supports; MANIFEST.sha256 gives the checksum of every file. No full texts or PDFs are included.
