PF1e (CRB Combat Maneuvers): "If you are hit by the target, you take the
damage normally and apply that amount as a penalty to the attack roll to
perform the maneuver." Capture the provoked AoO's damage in
_execute_maneuver and subtract it from the check total (floored at 0;
natural 20 still succeeds, natural 1 still fails; dropping below 0 hp
still forfeits). Escape and the Improved-feat exemption are untouched.

PF1e CRB 'Big and Little Creatures in Combat': a creature's natural
reach is a disk (a Large creature still threatens and strikes adjacent
squares), while a reach weapon doubles the wielder's natural reach but
'can't strike at their natural reach or less' (a ring whose dead zone is
the natural reach). The engine keyed the ring off reach_ft > 5, so
reach-10 natural attacks (giant belostomatid bite/claw, mounted
hooves) wrongly got a 5-ft dead zone.
AttackSpec gains reach_weapon (parsed from the combatant JSON); the
disk-vs-ring rule is centralized in _melee_reach_zone_cells and applied
consistently to weapon selection, melee usability, threatened squares
and charge end placement. Esha's Lance is the only reach weapon in the
shipped data; Large natural attackers keep the default (disk).

PF1e (CRB, Disabled): a disabled creature can take move actions without further injuring itself. retrieve_weapon and repair_weapon are budget-classified move actions (_ACTION_ECONOMY_MOVE_KINDS) but were absent from _DISABLED_MOVE_KINDS, so a creature at 0 hp paid 1 hp to draw or mend a weapon. Added both kinds to the exempt set.
