0.2.6-dev: 魂灵之影 only on a board of its field (#557, PR #558 by IceCodeNew adapted) — shadowTile requires Battle.onFieldBoard: a teammate's half counts, a boss field's hand / 临时整备区 rows and a solo boss field's empty half do not, no summon when nothing fits (the PR cut the bench rows by number, which left an empty half legal); the PR's test plus a solo / pair case; DESIGN §3, §31.10, SIM; golden: unchanged

 - Tile semantics come from `data/stages.json` legend: height (LOW/HIGH), buildable (ALL/MELEE/RANGED/NONE — the **effective** deploy type: the 深水区 `tile_deepsea` refuses deployment, NONE with the level's `buildableType` ALL kept, PRTS 深水区 地形信息 "拒绝部署（待补充）"; an active 特制水上平台 makes its tile deployable in the prep deploy map only, §21.3), ground-passable, fly-only, special terrain (mire, smog, deepsea, infection). The fenced tiles (围墙 `tile_fence_bound` / 围栏 `tile_fence`, legend `b`: LOW, buildable ALL, passable to flyers only) take units, which attack normally from there but block no ground enemy (PRTS 地形机制, §21.23). Melee chess may stand only on LOW tiles with buildable ALL/MELEE — except a melee chess whose trait reads 「可以放置于远程位」 (the 钩索师 / 推击手 branch trait: 歌蕾蒂娅, 崖心, 见行者, normal and elite, with any module or none), which may use the ranged tiles too (`shared/highGround.js`; the owner's decision of 2026-10-05, following PRTS — it reverses the 2026-10-04 one that allowed only elite 歌蕾蒂娅 with HOK-Y; on a 高台 it attacks and blocks nothing); ranged chess on ALL/RANGED **and** on LOW ALL/MELEE tiles ("所有行动内远程干员可部署在近战位"). Tokens follow their own `position`; a summon marked `ownerRange` (狼群, 流形: "只能部署在召唤者攻击范围内"; Mon3tr's 重构体 by her talent) goes only on a tile of its owner's attack range — the loadout grid rotated by the owner's facing around its tile (`PlayerState.summonRange`, §21.3) —, one marked `ownerRangeOutside` / `rangedTilesOnly` (凯尔希·思衡托's 战术锚点: "仅可以部署在凯尔希·思衡托攻击范围外的远程位") only on a 高台 outside it (`summonExcluded`, placement class `high`; 0.2.0).
 - **Facing (corrected, see research 09 §1.2):** like standard Arknights, every board piece has a direction `dir ∈ UP|RIGHT|DOWN|LEFT` chosen with the 4-direction deploy wheel after dropping it on a tile (also re-orientable in place); default `RIGHT`; persists across rounds. Range grid entries are `[dRow, dCol]` relative to facing RIGHT and are rotated: RIGHT `(dr,dc)`, UP `(dc,−dr)`, LEFT `(−dr,−dc)`, DOWN `(−dc,dr)` (row 0 = bottom); `rangeExtend` applies along +dCol before rotating — to a running skill's range too, unless that skill ignores 攻击距离 (`targeting.noRangeExtend`, 信仰搅拌机 S3, §21.16). The right-side Final Assault player is mirrored col `c→20−c` with RIGHT↔LEFT (UP/DOWN unchanged).

+### 31.10 魂灵之影 stays on the field's boards (#557, PR #558)
+
+Issue #557; PR #558 by @IceCodeNew, adapted.
+
+**Seen.** The boss / hidden simulation rect includes rows 0–1, the mapped hand and 临时整备区. `shadowTile` accepted any
+standable tile of her range there, so a bottom-row 维什戴尔 summoned 魂灵之影 onto the bench through her deployment talent
+or S3 when her nearer tiles were taken.
+
+**Now.** A candidate must also be on a board of this field (`Battle.onFieldBoard`, the "deployable" of the other summons
+and of the 突袭 landing): a teammate's half on a pair field counts; a boss field's hand / 临时整备区 rows and the empty half
+of a solo boss field do not. With no free candidate the summon is skipped. Range, occupancy and the order (nearest to her,
+then the lower row, then the left column) are unchanged. The PR cut the bench rows by number; that left a standable tile
+of an empty half legal, so the port uses the field's boards instead (the Raid-only empty-half exception, §29.13, stays
+Raid's).
+
+Sources: [PRTS 维什戴尔](https://prts.wiki/w/维什戴尔), the talent's nearest / lower-row / left-column deployable-tile rule;
+[issue #557](https://github.com/sganggs/Stronghold-Protocol/issues/557). No new [ASSUMED] rule.
+
+**Tests.** `test/content/op_wisdel.test.js`: the PR's case (boss and hidden fields, both sides, a full range and one free
+combat tile, through the deployment talent and an actual S3 activation), and a solo / pair case — her own free tiles
+filled, the empty half takes no shadow and the teammate's half does. Normative: DESIGN §3
+([geometry-time.md](../design/geometry-time.md)); API note: [SIM.md](../SIM.md). Golden: unchanged.
