- extension: data is an opaque []byte; New takes []byte and rejects empty
data; key 2 must be a non-empty shortest-form bstr; at most 64 extensions
per array; extension_version <= 2^32-1; CheckDisjoint is a linear merge;
optional DataValidator with ERR_EXTENSION_DATA_INVALID for known critical
extensions and Unusable reports for known noncritical ones.
- capsule, accesskey: frame limits on encode and decode with ERR_INTEGRITY;
Encrypt and MarshalBody decode their own output before sealing or
returning it; unusable extensions are reported.
- profile: period and genesis_time bounded to 2^53-1, genesis decoded as
unsigned.
- codec: Valid removed; empty values never encode as null.
- Regression tests for the nested-data seal/open asymmetry, the
nondeterministic verdict on NaN-keyed data and the quadratic disjointness
check; three new §64 mutations and five more.
- Fixtures: time_only_extensions regenerated with opaque data, new
time_and_key_portable_extension.dkk; genfixtures gains -only.

Extension data becomes a non-empty opaque bstr bounded by the frame of its
container; the base protocol never decodes or validates it. Arrays hold at
most 64 extensions, extension_version is bounded to 2^32-1 and the profile's
period and genesis_time to 2^53-1. The multiplicity exception is removed,
ERR_EXTENSION_DATA_INVALID is added, the §57 limits become MUST with an
explicit error mapping, §58 names the protocol's CBOR profile and §72 sets
the registration rules. §76 records the six reproducible cases behind the
change. The implementation follows in the next commit.

The Gitea server has no Actions, so scripts/check.sh is the gate. A
versioned .githooks/pre-push runs it; CONTRIBUTING explains how to
enable it per clone and when it may be skipped.

The module is imported as g.activething.com/go/DateKeys, the path the
project's Gitea advertises. The .github directory is gone: workflows
now live in .gitea/workflows, use the gitea.com action mirrors and
install every tool from its Go module; releases go to this Gitea with
goreleaser and a key-based cosign signature; Dependabot is replaced by
a nightly report of available updates. scripts/check.sh runs the same
checks on any machine and is the gate while the server has no runner.
SECURITY.md, README and CONTRIBUTING no longer refer to GitHub.

go.mod required go 1.26.0, whose standard library has known
vulnerabilities reachable from this module according to govulncheck.
Raise the minimum to the latest 1.26 patch release.

Reference implementation in Go, built from the implementation plan
(milestones M0 to M5): datekey, profile, provider, codec, agewrap,
extension, capsule, accesskey, the datekeys CLI, official vectors and
fixtures, the mutation corpus, fuzz targets, interop and live tests,
CI workflows, traceability and policy documents.
