re: the variant reading is refuted; HudResource is the in-game screen config

Browse Source 
Censused the 32 bundle-less in-game .prt names with the 68 as control:
4 of 32 appear as an element of some 2D bundle, against 58 of 68.
Being an element is normal for a part that exists; these are not
elements either.  Last iteration's 'not adopted' reading is refuted.
28 names are neither a bundle nor an element.

They are not unreferenced: a HudResource record inside the 2D paks' own
IDXD entries names them -- the in-game screen config, parallel to
tables.pak for menus.  GP_MAIN_GAME_E2D.pak has 6 IDXD entries; two
carry HudResource (24 named fields) beside ArmsStatus, Map, ArmsItem,
RangeFinder, Marker, Manuva, Number; two more carry the
ObjectiveMarker_*/TutorialMarker_* set.

Its values carry subdirectory prefixes -- Hitmark\, Lockon\ -- which my
hand-written prefix list never had.  So I rebuilt the negative the right
way round: harvested every IDXD field value containing a backslash, kept
the 60 commonest directories, and re-swept.  241/376 with the hand list;
241 with hand + harvested -- zero new resolutions.  After the language\
miss, this is the closure that counts: the prefix list came from the
disc, not from me.

Still open: whether the 28 are cut features or assembled at runtime from
sprites.  Nothing static separates those two.

Artefact +45 lines / 0 deletions; the other six regenerate
byte-identical.
