// server/sim/content/kits/ops/op-leizi2.js — 司霆惊蛰 (char_1043_leizi2) 自选 operator kit: 6★ 解放者 (近卫), an owned-6★
// pick of the tier-5 and tier-6 自选 slots; every skill, both talents, the trait and her module (LIB-X) at every form.
// Kit contract and the 自选 rules: ../README.md ("How to add an operator (自选)").
//
// Forms (data/backups.json units.char_1043_leizi2, the DIY slot statuses): normal = E2 Lv1, skills at rank 4, no module;
// elite = E2 Lv60, rank 7, LIB-X at stage 1 (tier 5) or 3 (tier 6). Full potential (the owner's decision of 2026-10-07).
// Sources: character_table / skill_table / battle_equip_table (zh_CN, as built into backups.json); the client's battle
// logic — buff_template_data (leizi2_tr, leizi2_e_002_tr, leizi2_s_cast, leizi2_t_1[atk_up] / [on_calcul] / [fly] /
// [trigger] / [buff_start], leizi2_s_2[try_add_atk], leizi2_s_3), her charpack (Trait buff: triggerInterval 1; the
// "thunder" ability: `_maxCount` 15, `_resetCountList` 3…7, `_rangeCastDelay` 0.25; S1 abilities s1_m / s1_l / s1_r:
// `_preDelay` 0.3, ground selectors; S3 attack: projectile_char_leizi2_s3 every `_triggerDelta` 0.28 s), the skill prefabs
// (skchr_leizi2_1: leizi2_s_1 lifeTime 0.5; skchr_leizi2_2: the flood-fill selector `_depth` 3, `checkHeightType`) and
// the projectile prefabs (projectile_char_leizi2_t_1 / [start]: lands `_delayTime` 0.15 s after its cast, ground + air;
// projectile_char_leizi2_s3: speed 1, `_lifeTime` 3.1, `_keepAlreadyHitTime` 0.6, ground only, magical, modifier key
// "leizi2", rebounds off its source), her skeleton's clips (Skill_1_Begin 0.5 s with OnAttack at 0.3; Skill_2_Begin /
// Skill_3_Begin 0.5 s; Skill_1_End / Skill_2_End 0.933 s, Skill_3_End 0.833 s) — and PRTS 司霆惊蛰 (talent / skill 备注).
// The official map of a battle is its field (`rect`): stage tiles beyond it (another player's half) are no tiles here —
// no strike falls there, S2's range and S3's currents stop at its edge [ASSUMED].
// - Trait (解放者) "通常不攻击且阻挡数为0，技能未开启时40秒内攻击力逐渐提升至最高+200%且技能结束时重置攻击力": the librator
//   profile (professions.js: no attack and block 0 while the skill is off, ATK +atk / max_stack_cnt every second up to
//   +atk while it is off, reset when it ends). Module LIB-X “一念” "部署后获得+100%加成": its hidden talent init_atk
//   (leizi2_e_002_tr: init_atk / (atk / max_stack_cnt) stacks at each deployment) — the profile's rampInit (her DISPLAY
//   trait part carries no blackboard, unlike 玛恩纳's, so the kit hands it over).
// - T1 明断 "攻击范围内每个地块每秒有10%的概率落雷对所有敌人造成相当于攻击力100%的法术伤害。未开启技能时起飞；技能期间攻击时攻击
//   力提升至107%" (full potential: 111 %):
//   · the strikes (PRTS 备注's algorithm, the thunder ability's numbers): every 1.0333 s from each deployment, each tile of
//     her current attack range — first seen: a counter at a random 0…14; else +1, and at 15 the tile is struck and its
//     counter restarts at a random 3…7; counters outlive a tile leaving the range and die with the deployment. A strike
//     lands 0.15 s after its cast: atk_scale_t × ATK arts on every enemy she can select on that tile, air units too
//     (PRTS 可对空). Counting pauses while she cannot act [ASSUMED: the ability does not cast under 晕眩 / 冻结].
//   · 起飞 while no skill runs (leizi2_t_1[fly] in her default mode only; gamedata_const ba.liftoff): flag `liftoff` —
//     no ground enemy selects her or is blocked by her (her block count is 0 then anyway). PRTS "开启技能时的降落动作与技能
//     结束时的起飞动作…期间自身不处于起飞状态，其中降落动作计入技能总时长": she lands at the cast and makes no attack for the
//     landing clip (S2 / S3 0.5 s, inside the skill's time; S1's attacks are its own), and after the skill she is up
//     again only when the take-off clip is over (S1 / S2 0.933 s, S3 0.833 s) — ground enemies may select her meanwhile;
//     her block count is the trait's 0 from the skill's end on.
//   · leizi2_t_1[on_calcul] (AtkScaleUp on ON_CALCULATE_DAMAGE while a skill runs; PRTS "对自身技能期间造成的所有伤害生效"):
//     an atkScaleMul ×atk_scale[skill_up] buff for the skill's time — her attacks (ai.js resolveHit) and every damage this
//     kit computes (strikes, S1, currents) multiply it. LIB-X stage 2+: the module talent's value (stage 3: 1.17).
// - T2 追责 "开启技能时，使攻击范围内所有地面地块落雷，对所有敌人造成相当于攻击力100%的法术伤害和2秒战栗" (full potential: 3 s): at every cast (each S1
//   charge too) every low tile of her attack range — the skill's, S2's flood fill included — is struck, ring by ring by
//   Manhattan distance from her tile (PRTS "自内向外"), 0.25 s per ring (the thunder `_rangeCastDelay`; 0.07 s under S1 —
//   leizi2_t_1[trigger] `_specialRangeCastDelay`), each landing 0.15 s after its cast: atk_scale_t2 × ATK arts and 战栗
//   (`tremble`) not_combat s on every enemy she can select there, air units too. The strikes start at the cast
//   [ASSUMED: leizi2_t_1[trigger] rides her landing clip's start event (≤ 0.17 s in), not modelled].
// - S1 浩气长存 (MANUAL, 可充能 3 次, data SEARCH): a 0.5 s skill (PRTS "技能持续0.5s"; skill prefab lifeTime 0.5) whose
//   range is the 3-19; no normal attack in it; 0.3 s after the cast (the abilities' `_preDelay`) three attacks — a 3-2 to
//   her left, her front and her right (PRTS: the 3-19 only explains the coverage) — each hit every ground enemy she can
//   select on it for attack@atk_scale_s1 × ATK physical (one on her own tile takes all three). "充能耗尽前特性不重置"
//   (leizi2_s_cast: the trait resets only when no charge is left): while a charge remains the ramp is kept.
// - S2 正霆摄威 (MANUAL, data SEARCH): at the cast her range becomes the low tiles reachable from hers in up to three 4-way
//   steps over the field (PRTS 备注: "任意高度类型为低地的地块以及干员自己所在的地块", "不存在地块数据的地块始终视为不合法";
//   a real attack range — rangeExtend applies), fixed for the skill; attacks hit attack@max_target_s2 targets for
//   attack@atk_scale_s2 × ATK physical, air units too (PRTS 攻击可对空); every lightning cast of hers while it runs
//   (leizi2_s_2[try_add_atk], the thunder ability's buffsToOwnerOnCast — 追责's strikes too) gives ATK +thunder_atk, up
//   to thunder_max_stack_cnt stacks, gone when it ends.
// - S3 天地通明 (MANUAL, data CUSTOM_RANGE on its 2-1): range 2-1, attack interval +base_attack_time s (flat), each attack
//   hits its target and every enemy within attack@range_radius of it for attack@atk_scale_s3 × ATK physical (air units
//   too: PRTS 普通攻击可对空); after each attack four currents leave the target's spot — up, right, down, left (screen
//   directions), 0.28 s apart (the first at the hit [ASSUMED]) — at 1 tile/s for 3.1 s, turning back before they would
//   enter a high tile, her own tile or the field's edge (PRTS "只在即将进入地块时进行反弹判定"), gone when she leaves (they
//   outlive the skill [ASSUMED]); each hits every ground enemy she can select on its
//   tile for attack@atk_scale_current × ATK arts, each enemy at most every 0.6 s per current, and — while S3 runs
//   (leizi2_s_3 ON_OUTPUT_MODIFIER, modifier key "leizi2") — with `prob` to 战栗 it not_combat s.
