The README describes the modules of part 4c and their notes: the input in
memory or from a ByteSource and what is read of it before the release;
the output and the sinks, required for their format, closed or committed
only at step 18 and aborted after any failure; the result, which never
throws for an invalid capsule; the credentials, the key of words among
them; the evaluator of stage 5 and accept; StandardExtensions with the
rules of the note; the differences of form with Go; and a bug of dart2js
of Dart 3.13 that an application for the web should know. It adds the
times of the opening, the generators of the vectors of stage 4c and their
files. The changelog has the part, its tests and the 15 faults injected,
all of them found on the VM and 13 on Node.js. The comment of
lib/datekeys.dart says what the library reads now.
