D039 - LibOrbisPkg named all six, and the derivations were right

The source was fetched and read: LibOrbisPkg/PKG/Enums.cs names every entry id, PKG/PkgBuilder.cs says how each is produced, Rif/LicenseDat.cs gives the licence structure. It is an open-source PS4 packaging tool - a writer, which is the third time a writer has been the thing that mattered.

entry	name	this project had
0x1	DIGESTS	derived: one digest per entry, table order, self-slot zero
0x80	GENERAL_DIGESTS	derived: digests of named things
0x100	METAS	derived: the entry table again
0x1002	PLAYGO_CHUNK_SHA	unknown
0x400	LICENSE_DAT	unknown
0x401	LICENSE_INFO	unknown

Four derivations, four agreements. They were established from packages before the source was read, and the source called them the same things. That is worth recording in that order: a derivation which survives meeting its source is stronger evidence than either alone, and selfish derive still re-checks all four against whatever packages a reader has.
