Subject: [PATCH] migrate: report every Anope record echo cannot model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The importer silently ignored NSMiscData, SeenInfo, Stats and the third-party
YouTube caches. List each in the skipped report — per-account misc fields by
owner, the rest as a counted summary — so an operator sees exactly what will
not carry over instead of discovering it after cutover.
