Approved refinements, each recorded with its reproducible case in the
§76 v0.8.2 subsection:
- §69.1: layered error model with normative precedence (frame, type tag
and version, CBOR profile and CDDL, then fields with their own code in
ascending key order; across steps the §63 order decides), with a scope
paragraph for the optional steps 5, 6 and 8.
- §55.1: normative trust table per section (who can write it, from which
step it is bound, what it never proves); §72: security-relevant claims
go in CONTROL_CBOR or under a signature, .dkk data is advisory.
- §31/§54: extension arrays in strictly ascending unsigned byte order of
extension_id (one rule for order and uniqueness).
- Gaps a second implementation needed: §28.1 malformed age headers,
§15/§19 latest unlock time and dk1_ reading rules, §22/§23/§57 length
lower bounds, §63 step 8 tlock argument comparison and step 9 order,
§12.1 profile validation with the drand chain-hash formula, §74 table
of implementation limits.
Reference alignment: .dkk errors only at step 9.a (new
OpenOptions.AccessKeyFile, used by the CLI), CR/LF in dk1_ is
ERR_DATEKEY_INVALID, BODY_LEN 0 is ERR_INTEGRITY, nil identities are not
credentials, and AccessIdentity tries every identity on every stanza so
its verdict does not depend on their order. dk1.json gains three
vectors; every other testdata file is byte-identical.
