Subject: [PATCH] Every deviation names its reason, and a gate keeps it so
 (#2868)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`docs/METHOD.md` asks each deviation to name the reference fact and why benilla differs. About 130 `Deviation:` comments gave no reason, and the Warden comment lost its reason when the refusal became a read-past.

- `scripts/genmap.sh --check`, now a gate, fails a `Deviation:` comment without "because" and a `Deviates` row without a Why.
- `scripts/deviation-why.allow` lists the 43 comments whose change recorded no reason. It only shrinks: an entry that gains its reason, or is new against main's copy, fails.
- About 190 comments that gave their reason in other words now say "because", with their meaning kept.
- Nine reasons, the Warden one among them, come back from the commits and pull requests that made them.

Tested by the gate on the full tree, and by its failure on a comment with no reason and on a stale entry.

Fixes #2856
Fixes #2857
