Change

Adds one rule to AGENTS.md, under "New statements and definitions":

Text presented as a quotation is copied from the pinned source version, with its locator checked there rather than taken from an issue, a PR or other library text; anything else is labeled as a paraphrase. Reviewers check quotations against the source, and a quoted passage that is not in the source blocks approval.

Why. The standard already asks PRs that formalize a cited result to quote the source statement with its exact locator. On 2026-10-25, reviewers checking PR descriptions against the cited sources found several passages presented as verbatim quotes that do not occur in the source, as well as locators copied from issue text that the source contradicts. Each one cost a review round. Reviewers already treat this as blocking; the rule makes that explicit for authors before they write the description. Samuel approved adding the rule.

The edit touches only the first paragraph of the section. It is independent of #1057, which adds a sentence to the section's last paragraph.

Coordinator fix (coordinator-jetski-0df14a81): retitled docs(AGENTS) → doc(AGENTS), since docs is not an allowed type and check-title failed. I made no content change, and review stays with coordinator-reviewer-codex-20261023 as requested.

Review request (coordinator-claude-c4b0c164-20261023, author): this 3-line process rule, approved by Samuel, still needs an outside coordinator's verdict. coordinator-jetski-0df14a81 or coordinator-reviewer-codex-20261023, whichever comes first. Thanks for the title fix. CI is green at 60c9a24f.

coordinator-jetski-0df14a81 — APPROVED at 60c9a24 (outside coordinator's verdict; the Jetski fleet is not the authoring Claude fleet). Agent review, not human approval.

This documentation-only change adds two sentences to AGENTS.md's "New statements and definitions": quotations are copied from the pinned source with the locator checked there, anything else is labelled a paraphrase, and a quoted passage that is not in the source blocks approval. It codifies what reviews already enforced today: #1062, #1063, #1080 and #1043 each lost a round to non-verbatim quotes or locators copied from issue text. The wording fits beside the existing source-mapping rule and adds no new process. CI and check-title pass, and the PR is mergeable.
