The filter 'Pistol' now matches 'Braises d'Automne (pistolet ?)' via

Golden test_tammara_vs_goblin updated: round-4 pistol shot gains the +1
feat bonus (total 15 -> 16 vs AC 16), turning the MISS into a lethal HIT
(17 damage, goblin 6 -> -11); the goblin dies on round 4 so the old
rounds 4-10 exchange and the draw are gone.

that stated the old values reworded consistently.

ctan cad35e2e13 fix(rules): cure spells damage undead instead of healing
SRD Cure Light Wounds: 'Since undead are powered by negative energy,
this spell deals damage to them instead of curing their wounds. An
undead creature can apply spell resistance, and can attempt a Will save
to take half damage.'

- _apply_heal_effect takes the rolled save; an undead target takes the
  rolled healing as damage (halved on a successful save; SR already
  resolved upstream, DR never applies to spell energy, no bleeding stop
  or stabilization). Living targets are bit-identical.
- cure_light/cure_moderate descriptions fixed: the SRD save line is
  'Will half (harmless)', not 'negates'.
- Deafened 20% verbal spell failure DEFERRED to the README « Limites
  hors perimetre »: SpellSpec carries no components data (would need a
  verbal flag on all 108 spells) and sound-based Perception is not
  modeled either.

ctan 3e19d2974e feat(rules): SRD Mage Armor spell + non-stacking armor bonus type
SRD spells/mage-armor.md: 'An invisible but tangible field of force
surrounds the subject of a mage armor spell, providing a +4 armor bonus
to AC' - 'School conjuration (creation) [force]', level 1, 'Casting Time
1 standard action', 'Range touch', 'Duration 1 hour/level (D)',
'Spell Resistance no'.

- data/spells/mage_armor.json: buff +4 armor to AC, 600 rounds (1
  hour/level modeled fixed, the shield.json convention). Description
  documents the known simplification: the engine bakes worn armor into
  the AC total and cannot see it, so the armor bonus stacks additively
  with that baked value (two mage armors still do not stack).
- effects.py: 'armor' added to BonusType; absent from _STACKING_TYPES it
  behaves as a keep-the-highest type (verified by resolve_modifiers
  tests).
- Spell-count pins 107 -> 108 (test_runner_spells, batch3, test_spells)
  and the README references.
- Golden transcript untouched (buff branch only fires when no offensive
  spell is selected; the lich still opens with Magic Missile).

ctan 881f2ef9b2 fix(rules): lich data conforms to the KB stat block
Verified against the KB (bestiary/lich.md, Bestiary Lich CR 12):
- bab 8 -> 5 ('Base Atk +5')
- Paralyzing Touch attack_bonus 10 -> 5 ('Melee touch +5 (1d8+5 plus
  paralyzing touch)') and marked natural: true (template: 'A lich has a
  touch attack that it can use once per round as a natural weapon [...]
  treated as a primary natural weapon' - no BAB iteratives per e5691bd)
- damage_bonus 5 -> 0: the +5 (1 point per 2 HD) is already in the
  1d8+5 formula and _resolve_swing adds damage_bonus on top (double
  counting: the old data dealt 1d8+10)
- ac 25/14/23 -> 23/14/21 ('AC 23, touch 14, flat-footed 21'; touch was
  already correct)
- saves 10/10/14 -> 6/7/11 ('Fort +6, Ref +7, Will +11')
- con_score 14 -> 10: 'Being undead, a lich has no Constitution score'
  (Con '—'); the int-only schema encodes 'no score' as the neutral 10
  (modifier +0), inert anyway since undead are destroyed at hp <= 0.
Left as intentional engine tuning (residual divergences, documented in
the final report): hp 100 vs 111, Str 12 vs 10, Int 20 vs 22,
initiative +6 vs +2, fear aura 30 ft/DC 22 vs 60 ft/DC 18.
Golden transcript untouched (the lich wins via Magic Missile before any
weapon swing; MM DC depends on Int, unchanged). Pinned a new
test_json_matches_srd_stat_block.

ctan 9a16ca0388 fix(rules): pass through 3+ size categories apart, entry provokes AoO
SRD Moving Through a Square: 'Any creature can move through a square
occupied by a creature three size categories larger than itself. A big
creature can move through a square occupied by a creature three size
categories smaller than it is. Creatures moving through squares occupied
by other creatures provoke attacks of opportunity from those creatures.'

- _can_pass_through: size ranks differ by >= 3 opens the through-gate
  (_blocked_hostile) while _blocked/_cells_free keep the end-gate
  ('You can't end your movement in the same square as another creature
  unless it is helpless').
- _check_enter_aoo wired into _walk_steps (move, explicit-destination
  move, and run all commit steps there): the occupant strikes once per
  fresh entry, capped by the per-round allowance; a dropped mover stops
  the walk. S4c co-occupiable pairs (Tiny-or-smaller) keep no-AoO sharing.
- _has_free_descent generalized to a descending BFS so a walk can cross
  a multi-cell Huge+ creature (one-step lookahead dead-ended inside).
- Golden transcript untouched (all 1480 tests green).

ctan 437507ee2c conformance: block 5-foot step on difficult terrain (SRD Take 5-Foot Step)
A 5-foot step is hampered by difficult terrain: stepping out of OR into a
difficult cell is blocked. _step5 (auto-directed) logs 'wait (cannot step)';
_step5_to (explicit destination) rejects with unreachable_destination.

ctan 7fc7a1d6ec fix(combat): Block run action when cant_charge flag is set
SRD Conditions Fatigued: A fatigued character can neither run nor
charge. _execute_charge already checked cant_charge; _execute_run did
not -- a fatigued/exhausted/entangled combatant could still run.

Added cant_charge guard to _execute_run (mirrors _execute_charge),
logging wait (cannot run) and returning ok. Two engine-level tests:
fatigued cannot run, exhausted cannot run.

ctan 2cc2ba1907 fix(combat): Thread 5-10-5 diagonal parity through all budget-consuming paths
The greedy move/run/flee/charge descent helpers hardcoded diagonal parity 0,
letting a speed-30 walker cover 6 diagonal cells (cell-count budget). Under
5-10-5 (SRD Movement, Tactical) the same walker covers only 4 cells
(1+2+1+2=6 squares).

Threading the running diagonal count:
- _best_move_step / _best_flee_step: accept diagonals_used param
- _descend_path / _run_line_path / _flee_path: track and pass parity
- _charge_end: use _path_cost_5105() instead of len(path) for max check
- _path_cost_5105: new helper; computes total 5-10-5 cost of any path

Updated golden paths in test_aoo_limit_one_per_round (5-cell path now
takes an orthogonal detour to avoid expensive 2nd diagonal), test_run_*
 (speed-30 diagonal move stops at 4 cells), and staggered_withdraw
(single-speed diagonal withdraw stops at 4 cells).

ctan e5691bdb6f fix(rules): natural weapons get no BAB iteratives, secondary attacks at -5
PF1e (CRB "Natural Attacks"):
- Natural weapons (natural=true) get exactly one swing per full attack,
  regardless of BAB (no BAB iteratives for natural attacks).
- Secondary natural attacks (secondary=true) attack at BAB -5; the
  Multiattack feat reduces this to -2.

ctan 59caf67909 fix(rules): undead and constructs are destroyed at hp <= 0
SRD Undead/Construct traits: 'immediately destroyed when reduced to 0 hit
points or fewer' — undead and constructs have no Constitution score, so
the PF1e hp <= -CON death rule does not apply to them.

- combat.py: CombatantState.death_threshold returns 0 for creature_type
  undead/construct (in addition to the opt-in dies_at_zero flag)
- tests: TestUndeadDeathThreshold pins undead dead at 0 and below, living
  keeps the disabled band at 0 and the dying band down to -CON

ctan 5e3505dc8c fix(rules): convert bane to a 50-ft enemies-only burst
SRD spells/bane.md: enemies within a 50-ft burst centered on the caster
take a -1 penalty on attack rolls and a -1 penalty on saving throws
against fear effects; Will negates. The -1 penalty is approximated with
the shaken condition (-2), matching the existing Doom approximation.

- bane.json: single-target condition -> AreaEffect burst radius_ft 50,
  targets "enemies", ConditionEffect shaken 10 rounds save_negates
  (range/save kept as medium/will for the registry pin)
- combat.py: _metamagic_transform_sub now copies AreaEffect.targets so
  an Extend Spell on an area spell preserves the allies/enemies filter
- tests: TestBaneEnemiesOnly (enemy in burst debuffed, allies/caster
  unaffected, successful Will save negates)

SRD spells/bless.md: 'The caster and all allies within a 50-ft. burst,

enemies) applied where area creatures are collected; bless.json now

ctan 0c141414a9 feat(rules): conform bulls strength, bears endurance and shield to the SRD
Bull's Strength now grants the SRD +4 enhancement bonus to Strength as
+2 melee attack, +2 melee damage and +2 CMB (three modifiers instead of
the previous +1/+1 approximation). Shield now uses a real shield bonus
type (+4 AC) instead of approximating it as deflection: the engine's
BonusType literal and stacking docs gain the shield type, which stays
out of the CMD bonus list (SRD Combat Maneuver Defense). Bear's
Endurance keeps its +2 Fortitude / +2 hp per HD and its description now
cites the SRD and flags the hp modifier as informational. Golden
transcripts updated: the buff log reports 3 mods and Tammara's pistol
attacks gain the extra +1 enhancement (d20=10+9-6=15).

ctan b84238792c feat(rules): scale healing spells with caster level
PF1e (SRD spells/cure-light-wounds.md): 'cures 1d8 points of damage +1
point per caster level (maximum +5)'; (spells/cure-moderate-wounds.md):
'cures 2d8 points of damage +1 point per caster level (maximum +10)'.
A HealEffect now carries the same DamageFlatScaling spec as damage
effects (S1b) and resolves it through effective_formula(caster_level)
at cast time, so the flat bonus grows with the caster and stops at the
stated cap. The engine passes the caster's level into _apply_heal_effect
(required keyword: no silent level-0 under-heal); Maximize Spell
maximizes the scaled formula. Cure Light/Moderate Wounds ship the SRD
values; inflict_light_wounds already carried its scaling_flat.

ctan a2a80b8690 feat(rules): add firearm misfire and the quick clear deed
Ultimate Combat Firearm Rules: a firearm attack rolling a natural 1 gains the
broken condition (weapon_broken, logged MISFIRE). Quick Clear now actually
clears the first misfired held firearm for 1 grit (reported no-op without
grit), and occupies the standard budget slot via _effective_slot; the
swift-consumed filter is slot-based so the standard deed survives.

ctan 7fb7ec55dd fix(rules): update initiative when a readied action fires
SRD Ready - Initiative Consequences of Readying: 'your initiative result becomes the count on which you took the readied action' and you 'act immediately ahead of the character whose action triggered your readied action'. _check_readied fired the payload off-turn but never touched the readier's initiative. It now calls _ready_shift_initiative, which rewrites the readier's _initiative_keys entry (trigger total + 0.5, keeping its mod and prior index) using the same tuple shape _execute_delay writes, so _build_round_order holds the new position for all following rounds. Deterministic: no RNG consumed, current round order untouched.

ctan 6702efc652 fix(rules): constrain a run to a straight line
SRD Full-Round Actions - Run: 'you can move up to four times your speed in a straight line'. _execute_run reused the Dijkstra move machinery, so it turned corners around walls. It now walks the straight Bresenham line (_run_line_path) and stops at the first obstacle (impassable terrain, difficult terrain, or a blocking creature), mirroring the charge clear-path logic. Keeps the 4x budget, step-by-step AoO provocation, moved_this_turn and the running/Dex-loss flag; a destination the straight line cannot honour is rejected (unreachable_destination).

ctan f5dc9da0c4 feat(rules): resolve one-round casts on the following turn
SRD Casting Time: a spell that takes 1 round is a full-round action
that comes into effect just before the caster's turn in the next round;
the caster then acts normally. _cast_spell now spends the slot and runs
the start-of-casting gates, then records a PendingCast (spell, target,
center, metamagic, slot level, hp at cast); delivery (touch attack, SR,
saves, effects) resolves at the start of the caster's next turn, before
the policy runs. Net hp lost in between forces the injured-while-casting
concentration check (DC 10 + damage + spell level, no Combat Casting) or
the spell fizzles; a caster knocked out of the fight loses it. Exposed
in the observation via pending_cast. Bounded model documented: net-hp
measurement instead of a per-damage-site hook; long (1 minute+) casting
stays out of scope.

ctan 3cc0502228 feat(rules): add the surprise round
SRD Surprise: when some but not all combatants are aware of their
opponents, a surprise round precedes round 1. Aware combatants take a
single standard OR move action plus free actions (swift and full-round
are dropped, full_attack collapses to one standard attack, withdraw
survives as the Restricted Withdraw standard); unaware combatants skip
their turn. New Combatant.aware flag (default true, parsed at the JSON
boundary) keeps every existing encounter bit-identical, exposed in the
observation snapshot. Unaware combatants are not flagged flat-footed
(documented simplification).

ctan a6cc5aef36 feat(rules): scale spell damage with caster level
DamageEffect gains optional scaling (1dX per N levels, capped) and scaling_flat (+X per N levels, capped) specs; effective_formula resolves them against the caster's level at cast time, so scaled dice flow through crits, energy resistance and metamagic like the base formula (CRB Magic - Caster Level). Loader rejects mismatched die types. Data: Fireball/Lightning Bolt 1d6/lvl max 10d6, Burning Hands 1d4/lvl max 5d4, Shocking Grasp 1d6/lvl max 5d6, Inflict Light Wounds +1/lvl max +5 (SRD-verified). Cure Light Wounds stays flat: its golden transcript pins 1d8+1 and HealEffect scaling is out of scope.

ctan 4659fae9f6 feat(rules): support cone and line spell areas
AreaEffect gains shape: burst|cone|line (CRB Magic - Aiming a Spell). Cones (90 deg, length = radius_ft) and lines (5 ft wide, Bresenham ray) originate at the caster's cell and are aimed at the resolved target or the U7b point-cast center; bursts are unchanged. Shared per-creature save + SR application; the observation area dict already exposes the shape.

ctan 5bf2850e2f fix(rules): use the attacker's best corner for cover bonus
SRD 'Cover': 'To determine whether your target has cover from your ranged attack, choose a corner of your square.' The ranged scorer in cover_bonus_cells took the MAX over all attacker corners (worst corner); the cover gate has_cover_cells and RAW use the attacker's best corner. Ranged cells are now scored min over attacker corners of (max over target-corner lines), then min over attacker cells - the bonus can no longer exceed what the gate admits. Melee keeps the worst-corner rule ('any line from ANY corner of your square'). Updated the two pins that locked the old worst-corner scores.

ctan a989266747 fix(rules): require adjacency or pull the target when grappling
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.
