Spec v0.8.2: corrections from the formal review
A formal review of the whole v0.8.2 text found it approvable after
these corrections, recorded in §76 ("Correcciones de la revisión
formal"):
- §27 no longer calls header_binding the authenticity of PUBLIC_HEADER:
it binds the header to the opened control, never authorship or date
(§55.1); the age MAC only protects against whoever lacks the file key.
- §63 steps 9 and 10: a network source (relay, Release API, cache) MUST
verify every response and gives ERR_RELEASE_UNAVAILABLE at step 9 when
none verifies; the step-10 codes are for a directly supplied release.
The reference already behaved so; TestReleaseFromANetworkSource pins
both paths.
- §54 and §72: registrations declare the objects and arrays where an
extension may appear, and a known extension out of place counts as
unknown there. The reference gains the optional extension.Placement
interface, used at steps 4, 9.a and 14.
- §63 step 11 fixes the GT serialization hashed by H2 (kilic/kyber order)
with the frozen vector H2(e(G1, G2))[:16] = cb87319f..., shared as
testdata/vectors/tlock_ibe.json; H2-H4 are cited to drand/kyber.
- Step 5 makes the SEALED_CONTROL read mandatory, step 15 names
ERR_HEADER_BINDING, §21 makes capsule_id 16 CSPRNG bytes a MUST, §76
is made accurate (four dk1.json vectors, the §36 time_only rule, two
cases rewritten against the texts that really existed), and editorial
fixes in §5, §36, §55.1, §69.1 and §77. §73 lists the three new
decisions.

Spec v0.11 approved: the text of the review, SpecVersion 0.11 and its SHA-256
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.
