A branch's local rounds can clear a sentence that states again a fact the tree already holds, and GitHub's review bot then finds it: it did on PR #472 and PR #474, each costing a push, a CI run and a bot run. This adds a question to REVIEWING.md's This repository in particular, as the maintainer chose on the issue: for each sentence the branch adds, has its key phrase been searched across every tracked file, and does its fact already live elsewhere? A second statement is a finding, under the standard's section 9, One fact in one place; a copy a rule requires is not.

The bullet gives the command: a Perl search over git ls-files with \W+ between the words, so that the phrase matches across a line break, a comment marker or a Markdown backtick. It reads names through <<>> after --, because the reviewer runs it on the tree under review: a tracked name ending in | would otherwise run as a command, and one named -i would switch on in-place editing.

Summary

Summary by CodeRabbit

• Documentation
  • Updated review guidance to check each sentence added by a diff against tracked files. The check looks for key phrases even when words are separated by non-word characters, and calls for reviewing matching files. Repeated statements of the same fact are flagged, with exceptions for copies required by the rules.

REVIEWING.md adds a repository-specific check for facts stated in sentences introduced by a diff. It describes searching tracked files for key phrases and reporting repeated facts under section 9, except for copies required by the rules.

Systems and components

• observed — REVIEWING.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in REVIEWING.md: Adds a check for whether each sentence added by a diff repeats a fact already in tracked files. The search uses \W+ between phrase words, so matches can cross whitespace, comments, or Markdown backticks; it reads each listed file. Repeating a fact is a finding under section 9, except for copies required by the rules.

ACK 35f495f

• Non-blocking, REVIEWING.md:545: the pattern [\s#]+ misses a phrase wrapped across // comment lines. The tree tracks files that use them (.markdownlint.jsonc, .vscode/*.json). Run against the tree, paragraph[\s#]+that[\s#]+lints finds no file, while [\s#/]+ finds .markdownlint.jsonc. There is an inline suggestion. This finding is left to the author.

- Line 544: Update the Perl input handling in the git ls-files check to open
each tracked filename as a literal path, rather than using -n and its
command-interpreting <> operator. Preserve NUL-delimited filename handling and
process each file’s contents through an explicit safe open or the
non-command-executing <<>> operator.
- Line 540: Update the phrase-search guidance in REVIEWING.md so searches for
multiword phrases account for Markdown delimiters between words, including
inline backticks, while retaining whitespace and heading-marker matching;
alternatively, instruct reviewers to search formatted and unformatted spellings.
- Around line 548-549: Update the section 9 “One fact in one place” finding rule
to exempt repetition required by repository standards, including copyright
notices mandated by COPYRIGHT, while retaining the rule for other duplicate
statements.

ACK 2545806

Not checked: the bullet's git ls-files -z | xargs -0 perl -0777 -e 'while (<<>>) …' -- command, and the PR's runs of it over hostile file names, were not run. No interpreter is at hand. I ran only its \W+ patterns, through ripgrep against the tree.
