feat(rules): alignment-gated spell damage for Shard of Chaos and Spear of Purity
...
DamageEffect gains an optional AlignmentGate (axis law_chaos/good_evil):
the immune side (chaotic/good) is wholly unaffected (no damage dice rolled),
neutral-on-axis targets take half damage with no condition (gate halving
stacks after the save halving), and the full side (lawful/evil) takes full
damage plus the gate condition on a failed save. Shard of Chaos maps the
SRD slowed to the engine staggered condition (the -1 penalty and half-speed
of slow are not modeled); the outsider-only 1d6/level variants are not
modeled (no outsider subtype). Non-gated damage spells are bit-identical.
Loader validates axis/side pairing with clear ValueErrors.

feat(rules): add alignment field to Combatant with axis gating flags
...
Adds the PF1e two-axis alignment code (LG/NG/CG/LN/N/CN/LE/NE/CE,
default N) to the Combatant model with a strict validator, derived
is_lawful/is_chaotic/is_good/is_evil properties, exposure in the
observation snapshot, and alignment values for all monsters and PCs
sourced from the bestiary KB and the Foundry sheets.

Guidance (new OneShotEffect), resistance (+1 resistance save buff, with the

fix(rules): resistance is a +1 resistance bonus on fort/ref/will saves for 1 minute - SRD spells/resistance.md grants the subject a +1 resistance bonus on saving throws for 1 minute (Will negates, harmless); the resistance bonus type already exists in the stacking model (effects.py BonusType), so the buff is expressible as a BuffEffect and was only deferred because _find_buff_spell returns the FIRST BuffEffect in known-spell order and cantrips cost no slots - encoding it would have made default_policy cast Resistance every round (for Tammara it would preempt Divine Favor and never kill anything); resistance.json now carries a BuffEffect (+1 resistance on fort/ref/will, 10 rounds = 1 minute) and _find_buff_spell skips level-0 spells (cantrips have no spell slot in the engine's budget - spell_slots_left has no level-0 key - and the policy deliberately never auto-casts them, a cantrip buff would be cast every round degrading the policy), so Resistance cannot preempt a leveled buff (Divine Favor) in the known-spell order; leveled buffs keep the historical first-match behavior (if the first one's slots are exhausted the buff branch gives up - the golden pins that); the resistance bonus type does not stack with itself (resolve_modifiers keeps the higher value); +9 tests (test_resistance.py: buff shape, cast on a willing ally consumes no d20 and applies without a save roll, the bonus rides save rolls, no self-stacking, expiry at 10 rounds, _find_buff_spell skips the slot-less cantrip / returns None without a leveled buff, _choose_spell_action proposes Divine Favor and never Resistance); golden untouched; 1714 tests green

fix(rules): guidance is a one-shot +1 competence bonus on a single attack roll - SRD spells/guidance.md grants '+1 competence bonus on a SINGLE attack roll, saving throw, or skill check' (duration 1 minute or until discharged); the engine had no spell effect that could write the one-shot attack track (aid_attack_bonus is hardwired to aid-another +2 and expires at the start of the beneficiary's next turn), and a persistent BuffEffect would misrepresent the discharge rule (it would boost every roll for a minute) and would become the first buff spell in the casters' known-spell order, degrading default_policy; a new OneShotEffect type is added (track/value/bonus_type/duration_rounds, parser 'one_shot', SpellEffect union, summary 'one-shot +X type on track'), stored as ActiveOneShot on CombatantState (one_shot_bonuses, decremented with the other duration-tracked effects, exposed in the snapshot), discharged by the FIRST roll of the encoded track via _discharge_one_shot (best value wins, each casting is its own charge) and folded into the resolve_modifiers pool so bonus-type stacking applies; the attack track rides the attack roll only, NOT the crit-confirm roll (the SRD grants it to a SINGLE attack roll, so unlike aid another the confirmation is untouched - _attack_roll_modifiers returns (pool_mod, attack_roll_mod) and resolve_attack uses the latter for the total while the confirm keeps the former); the save and skill tracks are wired in the mechanism (resolve_save folds a save-track shot into save_mods, resolve_skill discharges a skill-track shot into _skill_static_bonus via extra_mods) but guidance.json encodes the attack track only - the SRD 'attack OR save OR skill' choice has no declaration channel in the engine, so the attack-roll variant is encoded (documented); _apply_targeted_spell_effect dispatches OneShotEffect to _apply_one_shot_effect (a successful save negates it, 'one-shot negated'); guidance.json now carries the effect (1 minute = 10 rounds) and default_policy never casts it (cantrips have no spell slot and the one-shot type is not a buff/heal/offensive pick); _spell_effect_summary split into _damage_effect_summary/_non_damage_effect_summary to stay under the PLR0911 return cap; test_spell_registry_batch2._EFFECT_TYPES gains OneShotEffect; +14 tests (test_one_shot_guidance.py: cast-and-discharge on the next attack, not on the crit-confirm roll, save/skill tracks, stacking by bonus type, expiry at 10 rounds, save negation, snapshot exposure, no auto-cast by default_policy); golden untouched; 1705 tests green

fix(rules): a grazed caster cell no longer shortens a line spell - SRD Aiming a Spell: a line 'starts from any corner of your square and extends to the limit of its range' (Lightning Bolt: 'The bolt begins at your fingertips'), so the caster's own squares are origin space the line starts PAST and must not consume one of the length_cells squares; line_cells took a fixed ray[1:length_cells+1] window and dropped caster cells inside it, so a 2x2 caster's line came out one square short per grazed footprint cell (the old code documented this as a simplification); the ray is now extended (reach = length_cells + 1 + len(caster_cells)) and caster cells are skipped WITHOUT spending a length slot, so a multi-cell line runs its full length starting just past the footprint; 1x1 casters are bit-identical (the only skipped cell is the origin at ray[0], already outside the counted window); the barrier/LoE stop and out-of-bounds semantics are unchanged (a straight ray never re-enters a convex map); golden untouched (no line spell in it); +3 tests (grazed-cell full-length template, 1x1 bit-identical regression, engine-level reach of a foe the short line missed)

fix(rules): document the burst center-to-center convention as a deferred SRD approximation - the SRD (aiming-a-spell.md) measures a burst from a grid INTERSECTION with the far-edge rule ('count from intersection to intersection'; a square is inside only 'if the far edge of a square is within the spell's area'), but the engine's burst origin is a CELL (target_pos, centered_on_caster, resolved target) counted center-to-center 5-10-5 in _creatures_in_range; matching RAW exactly needs an intersection coordinate added to AreaEffect/Action.target_pos/the observation area snapshot contract plus a per-caster corner choice (the far-edge boundary result depends entirely on which of the cell's four corners is the origin), so it is DEFERRED with a precise explanation in areas.py and a pointer from _creatures_in_range; no behavior change, golden untouched

fix(rules): document the diagonal corner rule as stricter-than-RAW (SRD measuring-distance.md: 'You can't move diagonally past a corner' vs 'You can also move diagonally past other impassable obstacles, such as pits' - RAW blocks only both-flank corners; the engine requires both flanks passable for every diagonal, an accepted conservative approximation because relaxing it would rewrite Dijkstra paths and golden positions)

fix(rules): pin the high-ground +1 as melee-only with the SRD proof (Table 8-5 'Attack Roll Modifiers': 'On higher ground - Melee +1, Ranged +0') - engine verified conformant, no code change

fix(rules): document the blocks_los flag as LINE OF EFFECT semantics (SRD aiming-a-spell.md: 'A line of effect is canceled by a solid barrier. It's like line of sight for ranged weapons, except that it's not blocked by fog, darkness, and other factors that limit normal sight') - vision-only concealment terrain is not modeled; concealment rides conditions (miss_chance), not the map

fix(rules): cover grants a Reflex-save bonus against area effects (SRD cover.md 'Cover and Reflex Saves': +2 vs standard cover - half the AC value, so +1 partial/+2 standard/+4 improved; soft cover grants none) - _area_save adds terrain cover//2 from the effect's point of origin (burst center, caster square for cone/line) to Reflex rolls; resolve_save gains an explicit flat_bonus

fix(rules): bursts cannot affect creatures in total cover from the point of origin (SRD aiming-a-spell.md: a burst "can't affect creatures with total cover from its point of origin (in other words, its effects don't extend around corners)"; Line of Effect: a burst affects only what it has LoE to from its origin) - _area_creatures skips creatures whose occupied cells have no line of effect from the burst center
