- Format3 and the control of schema version 3, with the keys of
version 2 (spec 31). The PRELUDE still rejects VERSION 3 until the
reader opens format 3, in step 3, with the test data that expect it.
- The frame of BODY (spec 29.2): AREA_LEN, SECURITY_LEN and HEAD_LEN,
their limits against L and the zeros of the area, all ERR_INTEGRITY.
- security (spec 29.3, 29.7): the outer map, with the signature and
the seal as separately encoded byte strings, and its verdicts X, F0,
F1, S0, S1 and S2, which never fail. The first row that holds
decides, so a seal that breaks its schema is S2 before its type is
read. Writers of this version write it empty, 22 bytes.
- The head (spec 29.4): layer 2 with its type tag and version 1;
layer 3 with the CDDL, R1 and R8; layer 4 in key order, the comment
and the declared author, each file with R2 to R6c, R10 and its
layout, R7 and R9 over the tree, all ERR_HEAD_INVALID, and then the
critical extensions of the new extension.Head object.
- ERR_HEAD_INVALID is declared; All lists it once SpecVersion moves to
0.10 with the test data, in step 6.
- The control tests take format 4 as the caller error that format 3
was, as section 76 of the spec anticipated.
