Working documents in which the decision rules of the paper were fixed, archived as they now stand, in the language in which they were written (Chinese), with original file dates preserved in the zip (times stored in UTC). The documents were written on the dates listed in README_preregistration_1106.md; one of them is a working note rather than a formal registration. This deposit was made after most of the registered outcomes were known; it is therefore the first third-party timestamp of these files, not evidence that any rule preceded its data. That evidence rests on the file dates, on the export and download dates reported in the paper and on the material in evidence/: screenshots of file properties and extracts from the logs of the AI-assisted working sessions (Claude, Anthropic) in which the documents were drafted. The folder superseded/ holds one file as it stood before three additions were moved out of it. Changes made to a file after its registration date are listed in the README.
