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.
