Six bits, never more. Over all 835 turrets: 41 distinct values, max
0x3f, bits 6/7 set on none; per-bit 709/117/274/274/260/237. 0x00 (34)
= the empty Weapon_NULL hardpoints with YawLimit 0; 0x01 alone (439) =
craft hardpoints with YawLimit 2.5/1.0/0; 2-6 bits (362) = warship
mounts with YawLimit 45-180.
It tracks the MOUNT, not the weapon. UN_e107_ADAN_AAFrigate has eight
identical AAFrigate_AAGun turrets: GN_GunXS_01..04 are 0x1d and 05..08
are 0x2d -- same gun, same YawLimit 120, different mask. The Battleship
spreads five masks over GN_TGunL_01..05 / GN_TGunM_02..03, all firing
the same CAF_Ship_ASGun.
Which sector each bit denotes is NOT determined; six bits and the name
invite +-X/+-Y/+-Z or six hull faces, but nothing static fixes the
convention. Not adopted. Refuted on the way: bits 2 and 3 are not a
mutually-exclusive pair -- 188 turrets set both.
The 26 weapons no turret mounts are a coherent set: 11 _P player
variants, the nose/twin mounts, two _Child sub-munitions, the three
S16Boss_*, three Weapon_Test_*, and ADAN_Attacker_S_GunTurret.
Versatile_NNN ships nowhere -- 0 populated records across all 41
archives, only the ??? template row.
The two units one turret short: both extras are missile mounts with no
Frame. Elan_EX4 = NoseGun + Missile, both mask 0x01, both frameless;
AAFrigate_EX4 = eight framed guns plus one Ship_AAMissile at 0x0c with
no Frame. n=2, stated as the observed pattern, not a rule.
New artefact and regenerator; the other nine regenerate byte-identical.
