The author approved the draft v0.12 on 6 October 2026, as it stood: only
the date of its header changes, and no normative text is added. SpecVersion
is 0.12, the records of the fixtures and the vectors say so, and the frozen
security_cms.json and locator.json change only their spec field.
spec/README.md records the SHA-256 of the text, and the READMEs, SECURITY.md,
the traceability table, testdata/README.md and the changelog name v0.12.

The text of 44.1 now says what the reference already refused and a
second implementation that followed the text would have accepted:
segments of 1 to 63 characters that neither start nor end with a hyphen,
the scheme in lower case, 0x and the local names in either case, an IPv4
without leading zeros, and a CID of at most 128 characters in canonical
base32, with minimal varints and a digest of at least one byte. A port is
written without leading zeros: the reference accepted 0443 and 00443 and
refused 000443, the same number, and now refuses the three. Change 6 of
section 76 records it, and section 64 lists the cases.
locator.json is made again with 30 more addresses, 247 in all, and
TestAddresses checks the same rules.

- uri_cases: the first and the last address of each IPv4 block of 44.1,
with the public addresses next to them; the IPv6 blocks and the
addresses that hold an IPv4 one; the local names; characters outside
RFC 3986 and broken percent signs; "." and ".." segments; base32 that
is not a CID v1.
- mixed: a locator whose http and NAT64 addresses a reader rejects, and
whose third address it uses to find the rest.
- rest_cases: the rest alone, a host with bytes after the rest, a rest
with a byte changed, an offset that is not its own, a rest cut short.
- extension_cases: a locator sealed for round 1001 with a DateKey of
round 1000, and the other data that a reader cannot use.
- plaintext_cases: change 7, the bases 4094, 4070 and 3837 completed to
4096 with an empty key 6 or a length not in its shortest form, and a
defect in each field of the map.
- padding_cases: the bases 3837, 4070, 4094 and 4095 and those of the
next multiple, checked against the rule of 44.1.
The generator checks every case against this module and moves to its
own file. The vector is frozen: delete it to make it again.

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.

Fixtures format3_signed_cms (alg 2, two certificates, each sealed, F6) and
format3_sealed (alg 1 and a seal of seal_type 2, F4 and S4), with the
certificates, SIGNERS, the commitments, SEAL_SUBJECT, the token and the
result of each signer in their records. vectors/security_cms.json has 22
frozen areas with their context and verdicts (F1, F2, F5, F6, S1 to S5), and
vectors/locator.json the extension datekeys.capsule with its envelope hidden
in a host, its locator sealed with tlock, the padding at the boundaries and
the rules of the addresses. The README of testdata describes all of it.
