body.ts, security.ts and head.ts port format3.go of the Go reference at
spec-v0.10:
- body.ts: the frame of BODY (spec 29.2), AREA_LEN, SECURITY_LEN and
HEAD_LEN with their limits, and the zeros of the security area, all
ERR_INTEGRITY.
- security.ts: the empty SECURITY_CBOR that writers write, and the
verdicts X, F0, F1, S0, S1 and S2 of spec 29.7 with the Spanish lines
of the official SDK. The evaluation never fails and carries no code.
- head.ts: HEAD_CBOR in the layers of spec 69.1: R1 and R8 in the CDDL,
R8 by UTF-8 bytes and not by the UTF-16 order of JavaScript strings;
then the comment, the declared author, the paths with pathrule.ts, the
layout of the files, R7 and R9, all ERR_HEAD_INVALID; and the critical
extensions of the new extension object "head". decodeWrittenHead
leaves the extensions to the caller, for the self-check of the writer.
ERR_HEAD_INVALID becomes the 19th normative code, with its gloss.
Tests: the cases of format3_test.go and a few more, with the error
texts and the verdicts of the reference byte for byte, taken from it at
spec-v0.10 with a scratch program. Coverage 100 %.
