PF1e (SRD Combat Maneuvers): "Rolling a natural 20 while attempting a combat maneuver is always a success (except when attempting to escape from bonds)" - escaping a grapple is a combat maneuver, not bonds. _maneuver_escape now auto-succeeds on a natural 20 below CMD (the natural 1 auto-failure is unchanged). README updated.

PF1e (SRD Combat Maneuver Defense): "A creature can also add any circumstance, deflection, dodge, insight, luck, morale, profane, and sacred bonuses to AC to its CMD [...] A flat-footed creature does not add its Dexterity bonus to its CMD." _maneuver_cmd now sums the target's eligible AC bonus modifiers (plus the dodge/circumstance runtime bonuses from total defense, fight defensively and aid another) and drops the Dexterity bonus (keeping any penalty) while the target denies its Dexterity to AC. README updated.

PF1e (SRD Combat Maneuvers): "Creatures that are size Tiny or smaller use their Dexterity modifier in place of their Strength modifier to determine their CMB." _maneuver_cmb now swaps Str for Dex when the size is Tiny, Diminutive or Fine. True 0-reach and co-occupancy for Tiny-or-smaller stay unmodelled (5-ft grid abstraction), documented in the README.

PF1e CRB 'Overrun': 'If your maneuver is successful, you move through
the target's space. If your attack exceeds your opponent's CMD by 5 or
more, ... the target is knocked prone.' The engine knocked the target
prone on ANY success. A plain success (margin 0-4) now only moves the
attacker through; prone requires total - CMD >= 5 (_OVERRUN_PRONE_MARGIN).
