specVersion is 0.15 and testdata is synced with datekeys-go at 3c3e737
(branch v0.15): every file changes its spec field, mutations.json gains the
field source and four cases, and vectors/release.json and releases/ are new
(142 files).
release.dart, as provider of Go at 2eeca40, with its texts: encodeRelease
and decodeRelease of the release object (spec v0.15, 47.1) with the CBOR
profile of the library, its size first, then its type and version, then its
schema; parseRelease, which also reads drand's JSON with the rules of
encoding/json of Go for its three fields; verifyRelease checks the chain hash
a release names, ERR_PROFILE_MISMATCH, before its round and its signature;
ReleaseSupplier, EncodedRelease and supplyRelease, a release in the caller's
hand; and ReleaseArchive, the lookup of a local release archive (50), whose
failures are ERR_RELEASE_UNAVAILABLE at step 9.
open: OpenOptions.release takes a release in hand, exclusive with source. It
is not compared with the clock (step 9.c); Opened.clockBehind reports a clock
behind it, and the step 9 detail is Go's. Step 10 starts with the layers of
the object. A network source keeps its behaviour. Opened.release carries the
chain hash of the pinned profile.
Vectors: mutation_texts.json is regenerated with tool/mutation_go_texts.go,
which now replays each case with its source as testkit does: 149 cases
change only the detail of step 9 ("release supplied by the caller"), the
case "round not reached yet" now opens, and the four new cases are added.
release_vectors.json, the open vectors, and the formats, locator, security
and seal vectors come out the same at 3c3e737 but for their spec field.
tool/release_archive_go_texts.go writes the texts of provider.Archive on
edited archives; tool/release_copy.dart copies release.json, releases/ and
those texts to release.g.dart for the tests compiled to JavaScript.
errors_spec_test reads the spec at the commit of testdata/SOURCE.json rather
than at its tag.

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.

testdata/ is synced with datekeys-go at c531e93, the head of the branch
v0.12, whose testdata is that of 601e6d2, the copy of datekeys-ts. Every
file keeps "spec": "0.11": the draft v0.12 is not approved yet. From the
tag spec-v0.11 it brings the fixtures format3_unsigned and format3_note,
format3_seal_unsupported with seal_type 4294967295, the records of
format3_sealed and format3_signed_cms, the mutation corpus of 218 cases,
note.json, security.json with a context and lines, security_cms.json of
135 cases and locator.json.
The vectors that the generators of tool/ make from the testdata are
written again by Go at c531e93: mutation_texts.json, open_cases.json,
formats_*.json with formats_vectors.g.dart, ibe_vectors.json and
age_fixtures.json; release_vectors.json, primitives.json and the views
of open_vectors.g.dart come out the same. age.json does not read the
testdata, and stays frozen: age draws its keys from crypto/rand. The
tests count 26 fixtures and 218 cases, and the inspection of
format3_note gives the note of its record. No difference with Go.

A fault injected in the order of the layers of PUBLIC_HEADER, parsing the
DateKey before the rule across the extension arrays, passed the tests: no
random case had a DateKey of layer 4 and a fault of layer 3 together. The
generator now builds, for PUBLIC_HEADER, CONTROL_CBOR of the three
formats, the Provider Profile and the .dkk, each fault of a list alone and
each pair of them on a valid object, with Go's code and text: 153, 360,
153 and 181 cases, the .dkk sometimes with FLAGS 1 too. The cases use no
random value, so the other sections are the same as before.

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.
