The author approved the draft v0.14 with the recommendation of each of its
ten decisions; datekeys-go closes it with the tag spec-v0.14 (39b2033).
specVersion is 0.14 and testdata is synced with that commit: every file
changes its spec field, and vectors/tlock_steps.json is new (136 files).
Decision 8: validateProfile admits only bls-unchained-g1-rfc9380, with its
public key in G2, as validateDrand of Go since c041fa3, in its order and
with its text. formats_profile.json and its part of formats_vectors.g.dart
are regenerated with tool/formats_go_vectors.go on 39b2033: only the
thirteen cases of another drand scheme change. The other Go-generated
vectors change only their spec field.
tlock_steps_vm_test.dart walks tlock_steps.json value by value with the
code of the library, and tlock_steps_test.dart walks its copy,
tlock_steps.g.dart from tool/tlock_steps_copy.dart, compiled to JavaScript.
The comment of h3 in ibe.dart now says what the code does: it shifts the
first byte one bit to the right, as kyber does.

tool/mutation_go_texts.go ports scripts/mutation-go-texts.go of
datekeys-ts over the synced testdata of this repository, the tag
spec-v0.11: it replays every case of the mutation corpus as the testkit of
the reference does and writes the text of capsule.Open and its checks,
with the detail of each step, in mutation_texts.json. Where Go and the
corpus disagree on a code or a step it would say so in the case; Go at
c531e93 and at the tag spec-v0.11 agree with all 210 cases, and give the
same file, byte for byte.
tool/open_go_vectors.go runs in an export of datekeys-go, since it uses
internal/testkit, internal/cbortest and internal/inspectview, and writes:
- open_cases.json: capsule.Open on every fixture with each of its
credentials, and 117 openings of edited fixtures or with other options
at each step that the corpus does not reach: the frame, the fields, the
extensions and the bindings of a .dkk at step 9.a, the clock and the
failures of the release source, the age headers of steps 11 and 17, a
malformed X25519 stanza in INNER_ACCESS_AGE, CONTROL_CBOR and the BODY
of format 3 sealed again, the sinks and the output that fail, the
refusal of Accept and the unusable extensions of each object, with the
text, the step, the checks, the release requests, the state of the
sink and the content or the files;
- open_heads.json: capsule.DecodeHead and EncodeHead of heads of a fixed
seed, valid and broken in each layer of spec §69.1;
- open_notes.json: extension.CheckNote, Note, Header.UnusableNote and
extension.Standard with a note;
- open_inspect.json: the text of capsule.Inspect for each of the 5110
mutations of inspect_differential.json, where Go and the file also
agree, and the exact output of datekeys inspect -json with public notes;
- open_vectors.g.dart: seven small fixtures, their records and a part of
each file, for the tests that run compiled to JavaScript.
The edited capsules are sealed again with the file keys and the nonces of
the fixtures, as the testkit does, so the output is the same on every run.
