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.
