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.
