SRD Sunder + CRB 'Smashing an Object' / 'Conditions - Broken': weapons
carry Table 7-12 object stats (AttackSpec.hardness/hit_points/enhancement,
defaults by weapon class); a successful sunder deals the attacker's actual
physical weapon damage minus the target weapon's hardness, subtracted from
its hp. At <= half hp the weapon gains the broken condition - still usable
at -2 attack/damage, crits only on a natural 20 at x2. At <= 0 it is
destroyed (weapon_destroyed, unusable). The old flat str_mod+2 / durability
10 / synthetic 'disarmed' condition is gone. Firearm misfire carve-out kept
(broken firearms stay unusable until Quick Clear - misfire escalation not
modeled, documented).
SRD 'Grapple': 'If you successfully grapple a creature that is not adjacent to you, move that creature to an adjacent open space (if no space is available, your grapple fails).' _maneuver_grapple now pulls a non-adjacent target to the nearest free anchor whose footprint is adjacent to the grappler (5-10-5 distance, (row,col) tie-break, new _nearest_anchor_adjacent_to helper) and fails outright when no adjacent open space exists. Three tests: pull, no-space failure, adjacent no-move.

PF1e (APG Reposition / Drag): "For every 5 by which your attack exceeds
your opponent's CMD, you can move/drag the target an additional 5 feet."
Both handlers now walk 1 + margin//5 cells along the chosen (or auto-picked)
direction, stopping at the first obstacle or occupied square, mirroring the
bull rush scaling. README updated.

PF1e (SRD Combat Maneuvers): "Any penalties to a creature's AC also
apply to its CMD." _maneuver_cmd now folds negative AC modifiers into the
sum regardless of bonus type (grappled -2, other untyped penalties), and —
a maneuver being a melee attack roll — the prone -4 melee AC penalty.
Positive modifiers keep the eight SRD-listed types. The test that pinned
the old ignore-penalties convention is updated; README documents the rule.

PF1e (APG Steal): "Items held in the hands (such as wielded weapons or
wands) also cannot be taken with the steal maneuver—you must use the disarm
combat maneuver instead." The model carries no non-held items, so a
successful steal now takes nothing and logs
"nothing stealable — wielded weapons require disarm". README updated; the
retrieve_weapon tests keep locking the restoration mechanism directly.

PF1e (APG Reposition / Drag): "You can only reposition/drag an opponent
that is no more than one size category larger than you" — the same cap the
SRD puts on trip/bull rush/overrun. reposition and drag join
_SIZE_RESTRICTED_MANEUVERS, so a two-categories-larger target is rejected
outright (no roll, no AoO). README updated.

PF1e (SRD Combat Maneuvers): CMD = 10 + BAB + Strength modifier +
Dexterity modifier + special size modifier. The Tiny-or-smaller
Dex-for-Str substitution is CMB-only, but _maneuver_cmd reused
_maneuver_cmb for the base, so Tiny/Diminutive/Fine creatures got
10 + BAB + 2xDex + size and dropped Strength (live bug on the Tiny PC
ierlieth). The CMD base is now computed with str_mod directly; CMB
keeps its substitution.

PF1e (SRD Trip / Bull Rush / Overrun): "You can only [affect] an opponent who is no more than one size category larger than you." _execute_maneuver now rejects trip, bull_rush and overrun against a target two or more size categories larger: no roll, no provoked AoO, logged rejection. A _SIZE_ORDER ranking (Fine..Colossal, unknown -> Medium) backs the check; other maneuvers keep no size cap. README updated.

PF1e (SRD Trip): "If your attack fails by 10 or more, you are knocked prone instead" - a trip whose total lands at CMD-10 or below now knocks the attacker prone (1 round). PF1e (SRD Overrun): "If your overrun attempt fails, you stop in the space directly in front of the opponent, or the nearest open space in front of the creature" - a failed overrun from beyond adjacency walks the attacker to the free approach cell nearest the target; an already-adjacent attacker stays put. README updated.

PF1e (SRD Bull Rush): "your target is pushed back 5 feet. For every 5 by which your attack exceeds your opponent's CMD you can push the target back an additional 5 feet." _bull_rush_push (and the explicit-direction branch) now walk 1 + margin//5 cells, stopping at the first obstacle; a natural-20 auto-success below CMD floors the margin at 0 (base push only). README updated.

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).
