The author approved the text and the six open decisions on 1 October 2026.
The spec says now what the review left open: the form of the CMS signature
and of the TSTInfo field by field, the ESSCertIDv2 with SHA-256 written, the
padding of the locator at its boundaries, base32 CIDs, the addresses read
without decoding, the issuer shown by the rules of the holder, and the area
decided after the signatures. SpecVersion is 0.11, the records of fixtures
and vectors say so, and decrypt shows an mtime later than a valid seal as an
inconsistency, which 29.7 asks as a SHOULD.

The vector files of spec 67 for format 3, generated with the result
each case is written for, so that the generator fails when the
implementation or the tables change:
- paths.json: 83 paths with the result of the rules of one entry, the
violation worded as every implementation must word it, and 16 trees,
the paths of a head and the result of decoding it: U+00A0, accepted,
and U+3000, R6c, at both ends of a segment; best-fit, full-width
forms, U+00B4 of cp1253; 8.3 aliases with ~1; Cn; U+206A to U+206F,
tags and other ignorables; a dot and ZWJ, and ZWJ alone; 127 and 85
times U+0390; U+F03A; .datekeys-x at two levels; U+FF5E and U+1F600
in both orders; ab with and without ZWNJ; U+00BF, U+00A7 and U+2665,
accepted; VS16 after U+2764 and after a; ZWJ at the start, at the end
and twice; the rainbow flag and the flag of Scotland; b/.. and a.
- path_fold.json: 22 segments with their NFD and their key of R7,
among them the entries F of CaseFolding, the dotless i, the Kelvin
and Angstrom signs, Cherokee, Hangul and the whitelist dropped
before NFD.
- head_schema.json: 63 heads through layers 2, 3 and 4, in key order,
with the violation of each ERR_HEAD_INVALID; they add comments with
tags and with loose variation selectors.
- security.json: 21 areas with their verdicts, X, F0, F1, S0, S1 and
S2, among them key 2 that is not a byte string, a key 4, a byte more,
alg 0, an empty key with the seal intact, and a seal that breaks its
schema with an unknown seal_type.
- cbor.json gains the control of schema version 3.
A test replays every committed vector through the implementation, and
another checks that the files are current.
