feedback5 K2: stand-in kits for Stormeye, Pith and Raidian — every skill, talent and module at every form

Stormeye (char_611_acnipe; 空弦, 莫斯提马, 百炼嘉维尔 / 妮芙, 蕾缪安 / 异客): 风坠 rolls on every attack instance
(acnipe_t_1: ATK × atk_scale before DEF; S3 talent@prob), 风雨欲来 +0.2 SP/s after `delay` s without an attack
[ASSUMED reading], S1 ATK / ASPD / 100 DEF ignored, S2 an endless toggle (ATK +5 %, 2 targets), S3 3 targets × double
hit plus one physical ATK × 1.0 instance on a target at >= 90 % HP on the attack's first hit (acnipe_s_3[extra], no
风坠 / MAR-X on it); MAR-X stays the fastshot profile's flyScale.

Pith (char_612_accast; 烛煌, 焰影苇草 / 迷迭香 / 荒芜拉普兰德): splash from the trait blackboard, 12 RES ignored, ATK
+10 / +20 % on herself and the 【术师】 of the 4 tiles next to her, S1 ASPD + splash 1.5, S2 ASPD + ATK on every 【术师】,
S3 one ATK × atk_scale_aoe arts hit on every enemy of her range at the cast, then 2 targets, ASPD, splash 1.2 (PRTS
备注); SPC-X range (moduleRangeUp).

Raidian (char_614_acsupo; 灵知, 夕 / 安洁莉娜, 浊心斯卡蒂 / 仇白): 同调 on herself and the operators next to her (×
talent_scale in S3), 诱引 per PRTS 命中率 — one roll per enemy attack in her range, a miss cancels the whole attack
before the enemy riders (hit priority 300), S1 / S2 from the blackboards (S2 flat −0.1 / −0.2 s, 停顿 1.1 / 1.2 s), S3
y-4 + ATK + 脆弱 / 虚弱 aura with the 虚弱 stacking as 90 / 80 % (stackAs); S3 casts by the data's ACTIVE_RANGE;
DEC-X +0.2 SP/s with an enemy in range.

Triggers stay the data's (AUTO attack buffs Stormeye S2 / Pith S1 keep DEFAULT, as the W5C AUTO audit). No golden
scenario fields a stand-in: digests unchanged. Tests: test/content/standin_acnipe / _accast / _acsupo (27).

+// server/sim/content/kits/ops/standin-acnipe.js — Stormeye (char_611_acnipe) 补位 stand-in kit: 6★ 速射手 for 空弦 (T3, S3),
+// 莫斯提马 (T4, S2), 百炼嘉维尔 / 妮芙 (T5, S3 + MAR-X) and 蕾缪安 / 异客 (T6, S3 + MAR-X); every skill at every form.
+// Kit contract and the stand-in rules: ../README.md ("Stand-in kits").
+//
+// Sources: data/backups.json (character_table / skill_table / battle_equip_table at E2 Lv1 rank 4 and E2 Lv60 rank 7)
+// and the client's battle data (charpack char_611_acnipe, battle/buff_template_data.json — the templates quoted below).
+// - 速射手 trait 优先攻击空中单位 (data `targetPriority` 'fly', `canHitFly`); module MAR-X "攻击空中单位时攻击力提升至110%"
+//   (trait atk_scale 1.1, template acnipe_e_002_trait: CheckMotionMode FLY → AtkScaleUp on every damage calculation) is
+//   the fastshot profile's own (professions.js fastshot `flyScale` from the trait blackboard): no kit code. The module's
+//   HP / ATK are in the stats; at level 3 it raises 风坠 to 190 % (the composed talents).
+// - T1 风坠 "攻击时有25%的概率攻击力提升至180%" — acnipe_t_1: ON_CALCULATE_DAMAGE → Dice(prob) → AtkScaleUp(atk_scale): a roll
+//   on EVERY damage instance of an attack (each target, each hit of S3's double hit), ATK × atk_scale before DEF / RES.
+//   S3 raises `prob` to its talent@prob.
+// - T2 风雨欲来 "自身未进行攻击时，技力回复速度+0.2/秒" (sp_recovery_per_sec, delay 2): +0.2 SP/s once she has made no attack
+//   for `delay` s — [ASSUMED] the reading of `delay` (no text or PRTS note gives it), counted from her deployment too.
+// - S1 破空: ATK +atk, ASPD +attack_speed, 无视 def_penetrate_fixed DEF (defIgnoreFlat) for its 20 s.
+// - S2 心手合一 (自动触发, 持续时间无限): ATK +atk and attack@max_target targets until she is knocked out (a toggle). Trigger:
+//   the data's DEFAULT — an AUTO attack buff waits for her next attack like 能天使 S3 / 乌尔比安 S2 (W5C's AUTO audit:
+//   "attack modes / attack buffs" keep waiting); being endless it changes nothing but the moment of the cast.
+// - S3 旋臂: attack@max_target targets, attack@times hits each (二连击), 风坠 at talent@prob; and "攻击目标生命值高于90%时额外
+//   造成1次伤害": the S3 attack carries acnipe_s_3[extra] (`_onlyFeedActiveBuffToFirstOne`: the first hit of the double hit
+//   only) — FilterByTargetHpRatio GE attack@hp_ratio, then AdvancedApplyDamage PHYSICAL attack@atk_scale_extra × ATK with
+//   `_emitSourceOnCalculateDamage` false: one extra physical instance per target per attack, which neither 风坠 nor the
+//   MAR-X trait touches (no isAttack: no "攻击时" effect sees it). [ASSUMED] the HP ratio is read when that first hit lands,
+//   before its damage (as 异客's 机理分析 kit reads it; the order of the buff and the hit is not in the data).
