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/formats_go_vectors.go runs in the module of datekeys-go at c531e93,
without changing anything there, and writes test/vectors/formats_*.json:
the result, the normative code and the text of Go on inputs of a fixed
seed, valid and broken in every layer of spec §69.1, and on the fixtures
of testdata/, edited:
- the PRELUDE (229 cases), the steps 1 to 3 of capsule.Inspect on cut and
edited fixtures (492) and whole .dkk files (268);
- PUBLIC_HEADER (660) and CONTROL_CBOR of the three formats (618);
- Provider Profiles decoded (163) and validated as values (60);
- extension arrays (260), Canonical (80), CheckDisjoint (50), the
registries with places (120) and CheckWrite with Standard (60);
- dk1_ strings (466);
- RFC 3339 parsed (434) and formatted (80), Resolve (320), RoundTime (64),
Validate (128) and MaxRound (8), on profiles of other genesis times and
periods;
- PaddedLength and PayloadAgeLength at the boundaries up to L_MAX (474),
and the check of the padding of capsule.Open at step 17 on fixtures whose
PAYLOAD_AGE is encrypted again with an edited plaintext (56);
- the encoders on values and the decoders at the limits of spec §57 (90);
- the frame of BODY (260) and the zeros of the area (60).
The output is the same on every run. formats_vectors.g.dart holds every
eighth case as Dart constants, so that the differential runs compiled to
JavaScript too, on Node.js; a test on the VM checks that they are those of
the files. Every file is under 310 KB.
