StandardExtensions checks by default the data of datekeys.capsule with
checkCapsuleData, as locator.Standard of Go: when a .dkk is opened with
it, an extension whose data does not read is unusable, with the text of
Go. With validateCapsule: null it checks only that there is data, as
Go's extension.Standard without ValidateCapsule: the writer of a .dkk
keeps that one, as Go's writer does, and so do the tests of the formats
that compare with extension.Standard. Inspection and opening give Go's
results on every fixture and vector, and the tests of the locator use the
default registry.
lib/datekeys.dart exports locator.dart. The README has the section of
part 7a, its vectors and how the generator makes them; the changelog has
its entry, with its tests and its injected faults.

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.
