Putting it at the top of README.md worked, but it diverged a shared file: a
probe showed main editing the adjacent line conflicts on every merge. The
warning survived the conflict, so nothing was ever silently lost, but a file
that only exists on this branch has no such cost at all.
TOOLING.md carries the warning plus what CLAUDE.md would have said if it could
— the commands, the remote policy, and the two guards, which are local and
unversioned and so are absent from every fresh clone.
Shared files are byte-identical to main again: CLAUDE.md, README.md and
package.json. The divergence is now only files main has never had.
Trade-off worth knowing: gitea renders README.md on the branch page and does
not render TOOLING.md, so this warning is one click less visible than it was.
The pre-push hook, not the documentation, remains the guard that actually
stops a mistake.
