The five-day group-call outage from the deleted mrtc A record had no management
record at all - the fix, the diagnosis path, and the lesson lived only in the
session. The AAR records why nothing alarmed (DNS-01 certs and pods stay green
without an A record), the exact dating via token-vs-join counts, and the
countermeasure that already shipped (notfallhandbuch dns-soll.md + pruefe-dns.sh).
gruppenpruefung's nine real-timestamp findings join #0053's history pass -
same class, same decision, recorded so the next session repairs nothing
unilaterally.
