StandardExtensions checks by default the data of datekeys.capsule with
checkCapsuleData, as locator.Standard of Go: when a .dkk is opened with
it, an extension whose data does not read is unusable, with the text of
Go. With validateCapsule: null it checks only that there is data, as
Go's extension.Standard without ValidateCapsule: the writer of a .dkk
keeps that one, as Go's writer does, and so do the tests of the formats
that compare with extension.Standard. Inspection and opening give Go's
results on every fixture and vector, and the tests of the locator use the
default registry.
lib/datekeys.dart exports locator.dart. The README has the section of
part 7a, its vectors and how the generator makes them; the changelog has
its entry, with its tests and its injected faults.

lib/src/note.dart ports CheckNote, NewNote and Note of package extension
of datekeys-go at c531e93: checkNote and checkNoteData check the length,
the UTF-8 and the rules of text of the declared author, in that order and
with the texts of Go, on the bytes of the note as Go reads its string;
newNote, publicNote and unusableNote, and Header.publicNote and
Header.unusableNote. StandardExtensions checks the data of a note as the
Standard of Go does, and its parameter validateNote, which could replace
those rules, is gone.
lib/src/head.dart ports DecodeHead, EncodeHead and CheckHeadEnd of
format3.go: the limit of HEAD_LEN, the type tag and the version, the CDDL
with R1 and R8 on the UTF-8 bytes of the paths, never on the UTF-16 code
units of a String, and then the comment, the declared author and the files
with the rules of pathrule and their layout, by subtraction, and R7 and R9,
as ERR_HEAD_INVALID with the text of Go, and the critical extensions of the
head. decodeWrittenHead is the decoder without the critical extensions, for
the self-check of the writer of stage 6.
The tests read open_heads.json, open_notes.json, head_schema.json with the
detail of each ERR_HEAD_INVALID, the trees of paths.json as heads of files
of 0 bytes, and the head of each fixture of format 3.

lib/src/extension.dart ports package extension of datekeys-go at c531e93:
the structural rules of an array (1 to 64 entries in the order of the
UTF-8 bytes of extension_id, never of the UTF-16 code units of a String;
an extension_id of 1 to 256 bytes; data absent or non-empty) checked while
it is decoded and before it is written; Canonical, CheckDisjoint; the
registries with the optional data check and places of Go (an abstract
ExtensionRegistry whose defaults are those of a Go registry that is not a
DataValidator nor a Placement), ExtensionSet and KnownIn; CheckCritical
and CheckNoncritical, with and without the object; and CheckWrite with the
Standard registry of the extensions of spec §72, whose checks of the data
of a note and of a locator are given to it, since the rules of a note need
the tables of the rules of paths of stage 4a.
lib/src/schema.dart holds the helpers of the decoders of the objects, as
schema.ts of datekeys-ts: the key of a failing read, the required keys and
the extension arrays at their keys.
