Specification
DateKeys_Protocol_Specification_v0.8.2.md: frozen copy of the normative draft v0.8.2 (28 September 2026), taggedspec-v0.8.2. SHA-256:5cfa32034ea2ba02e77676e015cad7bba09796383afdda6634aaa017a5a23351. v0.8.2 replaces v0.8.1 with a normative change to extensions, refined before release (error precedence, trust model, extension order, and rules the reference had applied without normative text), amended (the canonical encoding of BLS12-381 points and the tlock stanza body) and corrected in two rounds of a formal review (an invalid release from a network source, the objects and arrays where each extension may appear, which an encoder must respect, the serialization of GT in the tlock H2, and a single code for any failure of a release source), all recorded with their reproducible cases in the specification's §76.DateKeys_Protocol_Specification_v0.9.md: frozen copy of the normative draft v0.9 (29 September 2026), approved by its author on that date and taggedspec-v0.9; this module implements it. SHA-256:36189e1e62f0f835b7665219aa63df7200cd89ac4e4e924f2705f970fa7c40a9. It adds capsule format 2, which hides until the unlock date the exact length of the content (the payload is padded) and the number of credentials (always 16 X25519 stanzas), and it makes the writer rules normative. A v0.9 reader still opens format 1, the format of v0.8.2. Its §76 records each change with its reproducible case.datekeys.cddl: the CBOR schemas of v0.9, both control versions included, with the encoding rules CDDL cannot express. Those of v0.8.2 are at the tagspec-v0.8.2.
