Read capsule format 2 of spec v0.9
Syncs testdata with datekeys-go at spec-v0.9 (7e2d83c) and moves the
reader to the DateKeys Protocol Specification v0.9. Both capsule formats
are read; a format 1 capsule keeps the verdict v0.8.2 gave it.
- framing: the VERSION of the prelude is the capsule format, 1 or 2
(Prelude.format, FORMAT_1, FORMAT_2, isFormat).
- control: decodeControl and encodeControl take the format; schema
version 2 adds payload_length (8 bytes, at most L_MAX) and padding
(1 or 2).
- padding.ts: the rules bloque256 and reforzado of spec §29.1, exact up
to L_MAX with BigInt bit lengths and ceil roundings, and the length of
PAYLOAD_AGE.
- open: exactly 16 stanzas in INNER_ACCESS_AGE of format 2 (step 12), P
at step 16, and at step 17 a plaintext of exactly P bytes whose
padding is zero; only the first L bytes are delivered, never the
padding. Step 17 is recorded when it passes, and step 18 gives the
bytes of content, as the reference does. Opened reports the format, L
and, in format 2, the rule and P.
- inspect: the JSON view carries format, as datekeys inspect -json.
- The page shows the format, warns about format 1, and gives the
padding rule and P once a format 2 capsule opens.
Tests: the twelve fixtures, the 125 mutation cases through open from
memory and from a Blob, the 4380 differential cases, padding.json, the
format 2 CBOR vectors, and padding.test.ts against a BigInt statement of
§29.1. The error texts of the 125 corpus cases were compared with
capsule.Open at spec-v0.9. ibe-vectors.json gains the seven format 2
fixtures from scripts/ibe-go-vectors.go; its frozen values are unchanged.

Specification 0.16 draft: a seal without accuracy, drand's JSON read strictly
The draft v0.16 of datekeys-go at 4f78854 (branch v0.16): SPEC_VERSION
0.16, and testdata, wordlists and annex synced from that commit. The
annex is §79 of the draft, with the CC BY-ND 4.0 license of the
specification in its title and the key of words in 79.7.
A seal without accuracy proves nothing before the opening date (§29.7,
§29.11, as 7e3b810): a valid seal is S4 only when its token carries
accuracy and t plus the accuracy is before round_time; otherwise S5,
with the first reason that holds: late, no accuracy under the BTSP
policy of ETSI EN 319 421 (0.4.0.2023.1.1), or no accuracy. cms.ts reads
hasAccuracy and the policy of the token (tokenIsBTSP); securitycms.ts
gives SealReason, Detail.sealReason and SignerLine.reason; S5 has no
fixed text any more, and verdictLines writes it and the line of a signer
of F6 with the reason, the texts of Go byte for byte (sealReasonText).
encryptFiles returns the verdicts of the area it wrote in
Encrypted.security, as Result.Security of Go, so that a writer warns of
a seal without accuracy (§62.1 rule 19).
drand's JSON is read strictly (§47.1, as b570338): parseDrandJSON, as
ParseDrandJSON of Go, reads RFC 8259 JSON in valid UTF-8 whose value is
an object, with no name repeated in any object, names compared exactly
once their escapes are decoded, a lone escaped surrogate malformed, the
round a number without sign, fraction or exponent from 1 to 2^53 - 1,
and signature and randomness strings, with the error texts of Go.
ParsedRelease is now a Release: no round above 2^53 - 1 is read. The
page reads the answers of the relays with it (drand.ts), as the client
of Go does, and the pasted release with strictJSON and jsonRound
(release-input.ts), so that it never reads another round than step 10.
Tests: security_cms.json with seal_reason (143 cases), the 38 JSON
inputs of release.json, the new cases of signature2_test.go and
drandjson_test.go (with the escapes written as escapes), and the new
fixtures: format3_time_and_key_words opens with the identity that the
words of its words_text give with normalizeWords and wordKey, in the
library and in the page, and format3_full_chunk, whose PAYLOAD_AGE ends
in a full STREAM chunk, opens. check-build.mjs counts words_text among
the secrets of the fixtures.
Reference files made again with Go at 4f78854: mutation-texts.json (its
spec field only), ibe-vectors.json (the two new fixtures, the rest
unchanged) and signing-vectors.json, in an export of 4f78854 with the
same frozen samples read again: the capsules are the same, and the
tokens of the sealer, without accuracy, now give S5.
