what

Two pages send readers to util/ paths that are not in the CRS repository. This applies to them the fixes that coreruleset/coreruleset#4888 makes to INSTALL.md and KNOWN_BUGS.md in that repository.

• content/1-getting-started/1-1-crs-installation.md, "Upgrading from CRS 2.x to CRS 3": the sentence that named util/id_renumbering/update.py and util/id_renumbering/IdNumbering.csv now names the two files as shipped with CRS 3.0.0, with a link to tree/v3.0.0/id_renumbering. It is the sentence that docs: fix dead references in rule comments and docs coreruleset#4888 puts in INSTALL.md.
• content/7-known-issues/_index.md: the "Apache 2.4 prior to 2.4.11" section is removed, as docs: fix dead references in rule comments and docs coreruleset#4888 does with the same entry in KNOWN_BUGS.md. Its workaround script, util/join-multiline-rules, was removed in chore: remove join multiline rules coreruleset#3877, and the platforms it names are end of life.

why

CodeRabbit noted on coreruleset/coreruleset#4888 that this repository carries the same two stale references (coreruleset/coreruleset#4888 (comment)), and I said there that I would open a separate pull request. The link check here does not catch them: they are paths in the text, not links.

The new sentence links to the files shipped with 3.0.0 rather than to the table on the rule ID page (content/3-about-rules/ruleid.md): that page presents it as the mapping to 3.0.0-rc1 IDs, and it differs from the file shipped with 3.0.0 (for example, 981044 maps to 912000 there and to 912120 in 3.0.0).

content/3-about-rules/creating.md (lines 268-269), on a page marked as possibly outdated, also tells rule authors to include their sources "within this util directory"; it names no path, so it is left as is here.

#222 also rewrites the known issues page and keeps this entry, with new wording that no longer names util/join-multiline-rules. If you would rather settle that entry there, I will take the known issues change out of this pull request.

Checked offline against main (ee326b0):

• the site builds with Hugo 0.164.0 extended, as in test.yml, with the same warnings as main, and english_test.sh passes;
• apart from the cache-busting timestamps and image IDs that change on every build, only these two pages change in the built site, plus the print page and the search index;
• a script that checks every util/ path and every coreruleset/coreruleset blob or tree link in content/ against the repository tree (at main, or at v3.0.0 for links to that tag) reports the three paths above on main and nothing on this branch.

refs

• docs: fix dead references in rule comments and docs coreruleset#4888 (the same fixes in INSTALL.md and KNOWN_BUGS.md)
• Rule comments and docs point to missing files; the update commands documented for 932205 and 932207 fail coreruleset#4887 (the dead references in the CRS repository)
• chore: remove join multiline rules coreruleset#3877 (removal of util/join-multiline-rules)
• docs(known-issues): document early blocking #222 (rewrites the known issues page)

ai disclosure

tools used: Claude Code (Claude Opus 5.5)

assisted with: checking the two references CodeRabbit flagged and searching content/ for others, the two edits, the checks above, and the text of this description

review performed: Claude Code ran the checks above in an offline sandbox and reverted each edit on its own to confirm that the path check fails without it; I reviewed the diff and this description before opening the pull request.
