Follow the draft v0.12: testdata at 601e6d2, the reader of certificates, the texts of the verdicts

Browse Source 
testdata is synced with the head of the branch v0.12 of datekeys-go
(601e6d2); SPEC_VERSION stays 0.11 until the author approves the draft.

- CMS as Go reads it at the draft v0.12 (review of 2 October, T2, T6 to T8
  and the TypeScript side of E7 to E9):
  - the certificate field by field with the profile of section 29.10, its
    errors in CertificateError with the texts of Go; one that breaks it
    decides nothing unless a SignerInfo names it, and two copies are one;
  - the text of a name only from UTF8String, PrintableString, IA5String,
    TeletexString in ASCII and BMPString without surrogates, never from an
    attribute that appears twice; the holder by givenName and surname
    before the commonName, the issuer by its commonName or its
    organizationName;
  - object identifiers by the bytes of their DER; a SET OF may repeat an
    element; RSA with NULL parameters and an odd modulus; a key of another
    scheme than its algorithm is invalid; a messageImprint of another
    length is S3; the crls of a token decide nothing;
  - DER: UTCTime and GeneralizedTime in their X.690 forms with a date that
    exists, the restricted string types as primitive, the accuracy as
    minimal INTEGERs. The test of cms.test.ts that compared a function
    with itself has an expected value of its own.
- The verdicts in the texts of the draft: names between « and », shown
  with at most 64 code points and no two spaces in a row, or their SHA-256;
  in F6 the authority of each seal and the warning that nobody checks who
  issued it; foreign signers in Spanish; times with their fraction.
- security.json in its context with lines, and the 135 cases of
  security_cms.json, compared field by field, lines included.
- The 218 cases of mutations.json, with the texts of capsule.Open
  regenerated by scripts/mutation-go-texts.go, and ibe-vectors.json with
  the fixtures format3_note, format3_unsigned and the new
  format3_seal_unsupported; its frozen values do not change.
- note.json, run with checkNoteData, publicNote and unusableNote.
- inspect reads the public note on demand, only for a header with one, so
  that the Unicode tables never load with /inspect; the view of inspect
  -json gives public_note and public_note_unusable, as Go.

A Go/TypeScript differential of 63,623 security areas, made from the
vectors, edited element by element and signed afresh with varied
certificates, tokens and authorities, gave no difference in verdicts,
results or lines; the code before this change differed in 13,296 of the
first 42,986.

literal, and a port from 1 to 65535. bytes are missing (§44.1). Among them the bases 3837, 4070, 4094 and 4095,
which give 8192, those of the next multiple, which give 12288, and their
neighbours.
- `uri_cases`: an address and whether the rules of §44.1 accept it (`ok`):
the scheme, the authority without a percent sign, userinfo or a backslash,
the port, each character outside RFC 3986 and a percent sign without two
hexadecimal digits, the "." and ".." segments, written or with `%2e`, in the
path but not in the query or the fragment, the first and the last address
of each IPv4 block of §44.1 with the public addresses next to them, the
IPv6 blocks and the addresses that hold an IPv4 one, the names that only a
machine or a local network resolves, a last segment that is numeric or
starts with `0x`, and base32 that is not a CID v1. Then what the text of
v0.12 fixes besides: segments of 63 and 64 characters, or with a hyphen at
an end, the scheme, `0X` and the local names in upper case, an IPv4 and a
port with leading zeros, and a CID with the bits left over not zero, with
padding, in upper case, with a varint that is not minimal, with an empty
digest, or of 128 and 136 characters.
- `mixed`: a second locator of the envelope, sealed for round 1000 too. Of its
`addresses`, a reader rejects the first two, an `http` one and one of NAT64
that leads to 127.0.0.1, and uses the third (`usable`), which finds the rest
in `host`: the locator reads all the same. A writer never writes it.
- `rest_cases`: a `resource` as a reader downloads it, the `offset` that an
address gives, and whether the rest read there opens the envelope (`opens`):
the rest alone, the host with bytes after the rest, of which only
`rest_size` bytes from the offset are read, a byte of the rest changed, an
offset that is not its own, and a rest cut short.
- `extension_cases`: data of `datekeys.capsule` and whether a reader can use
it (`ok`): without a locator, and unusable, with only
`ERR_EXTENSION_DATA_INVALID`, for a locator sealed for round 1001 beside a
DateKey of round 1000, a locator that is not an age file or is empty, no
DateKey or one that is not canonical, a note that breaks its rules and a
key 3.
- `plaintext_cases`: plaintexts of a locator of the envelope, each with the
defect that its name says or none, and whether a reader reads them (`ok`).
The bases 4094, 4070 and 3837 completed to 4096 with an empty key 6 or with
its length not in its shortest form, against the 8192 bytes of the base
4094 (§76 of v0.12, change 7); eight addresses and nine, none, an empty one
and one of 1025 bytes, which make the whole locator unreadable, an offset of
0 written, an offset and a `resto_size` of 2^53; two blocks where one
suffices, padding that is not zeros, a byte less and a byte more. An
address that breaks the rules of §44.1 does not make a locator unreadable:
that is `mixed`.
## `vectors/note.json`
The data of the public note, `datekeys.note` version 1 in the noncritical
array of PUBLIC_HEADER (spec §24.1): text in UTF-8, from 1 to 1024 bytes, that
meets the rules of the declared author of §29.6. A writer writes a note only
when its `result` is `ok`; a reader shows it only then, and otherwise treats
the note as unusable, never the capsule (§54), and says so.
```json

`detail` is the text of the rule that a note breaks, without the code, as the
reference words it. Among the cases: letters that are not ASCII and an emoji,
an emoji with VS16, 1024 bytes, accepted; no byte, 1025 bytes, a tab, a line
