Summary

Implements support for four Ogerpon-family Pokémon cards from the Fantastical Parade (B2) set, including their unique attack mechanics and passive abilities.

Key Changes

New Attack Mechanics

  • ExtraDamageIfCombinedActiveEnergyAtLeast: Teal Mask Ogerpon ex's Energized Leaves attack deals bonus damage when combined active energy meets a threshold
  • CoinFlipChargeBench: Hearthflame Mask Ogerpon's Hearthflame Dance flips a coin to optionally attach energy to a benched Pokémon
  • CoinFlipAlsoChoiceBenchDamage: Wellspring Mask Ogerpon's Wellspring Dance flips a coin to optionally deal damage to opponent's bench

New Ability Mechanic

  • SoothingWind: Teal Mask Ogerpon ex's passive ability that prevents status conditions on energy-bearing Pokémon
    • Implemented in State::apply_soothing_wind() for end-of-turn maintenance
    • Integrated into State::apply_status_condition() to block status application

Implementation Details

  • Added atomic damage resolution for bench-damage attacks via ApplyDamage action to prevent stale slot issues when KOs occur
  • Enhanced damage prevention checks to handle cases where defending Pokémon may be KO'd before bench damage resolves
  • Added safety checks in on_end_turn() hook to handle scenarios where active Pokémon is absent
  • Updated get_intimidating_fang_reduction() to gracefully handle missing active Pokémon

Test Coverage

Added comprehensive test suite (tests/ogerpon_test.rs) covering:

  • Energized Leaves damage thresholds (below and at/above 5 combined energy)
  • Soothing Wind status prevention (energized vs. unenergized Pokémon, multiple status types)
  • Hearthflame Dance base damage and heads-triggered bench attachment
  • Wellspring Dance base damage and heads-triggered bench damage
  • Cornerstone Dance base damage and heads-triggered damage reduction

Card Mappings

Updated effect_mechanic_map.rs and effect_ability_mechanic_map.rs to map card text to the new mechanics for all four Ogerpon variants.

- Teal Mask Ogerpon ex: Soothing Wind passive ability + Energized Leaves attack
- Hearthflame Mask Ogerpon: Hearthflame Dance (coin flip charge bench)
- Wellspring Mask Ogerpon: Wellspring Dance (coin flip also bench damage)
- Cornerstone Mask Ogerpon: Cornerstone Dance (extra damage at combined energy threshold)

New mechanics: ExtraDamageIfCombinedActiveEnergyAtLeast, CoinFlipChargeBench,
CoinFlipAlsoChoiceBenchDamage, SoothingWind ability (passive status immunity)

Robustness fixes for deferred-action edge cases:
- on_end_turn: early return when active is None
- modify_damage: graceful None for attacker/receiver slots
- apply_defender_damage_prevention_if_needed: graceful None for defender
- heal_active_your_pokemon: guard against None active

Added 11 integration tests in tests/ogerpon_test.rs

Resolved conflicts in:
- src/actions/abilities/mechanic.rs: added new variants from main alongside SoothingWind
- src/actions/apply_abilities_action.rs: combined SoothingWind + new passive panic arms
- src/actions/effect_ability_mechanic_map.rs: kept both SoothingWind + DoubleGrassEnergy entries
- src/hooks/core.rs: kept graceful None guard + adopted AbilityMechanic check for Intimidating Fang
- src/move_generation/move_generation_abilities.rs: added SoothingWind + new passive false arms

…d bench damage atomicity

- Soothing Wind now cures all energy-bearing Pokémon immediately when Ogerpon
  enters play (apply_place_card), rather than at end of turn. Removed the
  end-of-turn apply_soothing_wind() call — the ability prevents status, not cures it.
- Added apply_soothing_wind_for_player() helper (single-player, pub(crate)).
- Added ExtraDamageIfDefenderPoisoned mechanic for Venoshock attacks (+40/50/60/70
  extra damage if opponent's active is Poisoned). Mapped 4 text variants.
- Fixed coin_flip_also_choice_bench_damage to bundle active+bench damage atomically
  in a single ApplyDamage, preventing stale slot references after KO/promotion.
- Reverted heal_active_your_pokemon to hard get_active_mut (soft-None guard was
  masking the now-fixed deferred bench damage ordering bug).
- Graceful None guards in apply_defender_damage_prevention_if_needed and
  modify_damage for attacker/receiver slots.
- 3 new ogerpon tests: cure-on-play, Venoshock extra damage, Soothing Wind
  prevents Venoshock bonus.

https://claude.ai/code/session_019RHHC3bwN4LP6v2FrqQq3U
- Remove unused `mut` on game variables in 3 state-only tests
- Switch Venoshock test targets from Bulbasaur (Grass, weak to Fire) to Charmander
  (Fire, weak to Water) so Salandit's Fire attacks don't trigger weakness, keeping
  expected HP values correct (50 and 10 instead of KO/wrong totals)

https://claude.ai/code/session_019RHHC3bwN4LP6v2FrqQq3U
The guard was masking a now-fixed root cause: deferred bench damage could
be processed after a KO/promotion, leaving the active slot empty. Since
coin_flip_also_choice_bench_damage now bundles both damages atomically,
the stale-state scenario can't occur. Use get_active() directly so a
future None panics loudly instead of silently skipping damage prevention.

https://claude.ai/code/session_019RHHC3bwN4LP6v2FrqQq3U
EndTurn only appears when move_generation_stack is empty, which means
promotions are always resolved first (trigger_promotion_or_declare_winner
uses .insert(0, ...) so promotions settle before the stack drains).
By the time on_end_turn fires, the active is always present.

The modify_damage and get_intimidating_fang_reduction guards were also
masking the now-fixed deferred bench damage root cause; atomic ApplyDamage
ensures attacker and receiver slots are always populated during damage
resolution. Restore .expect() so future None values surface as real bugs.
