Every sentence of prompts/REPO_POLICIES.md is rewritten against the
sentence rules: one idea per sentence, about 30 words at most, lists as
bulleted lists, subject and verb early, the main rule before any
exception. No rule's meaning changed: nothing is added, removed,
loosened or tightened, every reason stays, and code blocks, digests,
URLs, file names, commands and quoted strings are unchanged. Both repo
checklists carry the same rewrite of the sentences they quote word for
word.
