check / check (push) Successful in 1m1s
Nameservers may answer with DNS names in any letter case. For eeqj.de, y.ns.joker.com answers in upper case while its peers answer in lower case, so the inconsistency check fired on every cycle. extractRecordValue now lower-cases CNAME, MX, SRV and NS targets, so the inconsistency check and the record-change check both compare names regardless of case. A, AAAA, TXT and CAA values are unchanged. State saved before this change can hold upper-case names, which report a one-time record change on the first check after upgrading. Model: opus-5-5
