+- 拖动时**指针 / 手指所在的格子**就是落点并高亮。这一格可以放下（棋盘或整备区）时，干员模型直接站在这一格上，和官方部署一样：手指在格子里移动时模型不动，移到下一个可放下的格子就站到那一格；指针不在可放下的格子上时（例如在商店栏上），模型跟在指针 / 手指下（脚在指针下方约半格）。鼠标和触屏一样。装备拖到哪个格子，就配发给那个格子上的干员；在商店栏上松手则放回原位。

 - **召唤物手动摆放**：把带可部署召唤物的干员放上棋盘后，它的召唤物会进入整备区（赫默的医疗探机、巫恋的诅咒娃娃、凯瑟琳的 2 个支援装置、浊心斯卡蒂的海嗣、伺夜的狼群、缪尔赛思的流形；同一干员的召唤物叠在一格，不占部署位），像干员一样拖到棋盘上并选方向。凯瑟琳的支援装置给**它面朝的那一格**上的干员加屏障，所以要放在干员旁边、朝向干员。**战术家的援军**（伺夜的狼群、缪尔赛思的流形，也就是选战术点）和官方一样**只能放在召唤者的攻击范围内**：拖动时只有这些格子会亮起；之后在原地给战术家换朝向时，不在新攻击范围里的援军会退回整备区（还在范围里的保持不动；整备区和临时整备区都满、援军无处可退时，这次换朝向不生效并提示「整备区已满」）。撤退或出售干员时它的召唤物一起移除；**移动干员到别的格子时（包括把召唤物拖到干员身上交换位置），它已摆放的召唤物会退回整备区**，需要重新摆放。整备区满时退回的召唤物进入临时整备区，休整期结束还没处理的会在下一回合重新回到整备区。
 - 作战中：海嗣、狼群、流形、支援装置开战时就在摆放的位置部署；医疗探机、诅咒娃娃开战时也在摆放的位置免费部署一次（持续 10 / 15 秒，和官方一样不需要先开技能），之后所属干员每次发动技能时再次在原位出现；所属干员被击倒、再部署回场时，技能给的那一个如果还没出现，会立刻出现。巫恋退场时诅咒娃娃随之撤退，赫默退场时已出现的医疗探机不受影响。医疗探机、诅咒娃娃、海嗣（以及自选干员的工程蓄水炮、沙地兽、打字机、本能的召唤）这类不会受到攻击、到时间就离场的召唤物不受任何伤害（活性源石也一样）、也不会被治疗，它们的血条就是倒计时：随时间减少，空了就离场。琳琅诗怀雅二技能的香槟炸弹也不会掉血（活性源石和各种伤害都不会）、不会被治疗，不会因为生命值而消失，只在「见面礼」炸到碰到它的第一个地面敌人后消失（维护者 2026-10-08 的决定）；隐匿（没有被反隐、也没有被阻挡）或沉睡的敌人选不中，不会触发它。医疗探机、诅咒娃娃、支援装置、海嗣没有摆放就不会出现；狼群、流形（战术家的援军）没有摆放时会在战术点出现。狼群最后一只狼影被击倒后进入战术点形态：暂时离开战斗（不阻挡、不攻击、不会被攻击，格子仍然占着），经过狼影的恢复时间（25 秒）后在原地满血、带着 1 只狼影回来，之后重新开始每 25 秒加 1 只狼影；伺夜退场时狼群随之撤退，伺夜再部署回场时狼群重新带着 2 只狼影出现。

+### 27.62 A dragged operator stands on the tile it will drop on, as in the official deploy drag (the report in PR #403 by @bubububaoshe — not merged: the pick stays the pointer's tile; the owner's recording of the official game, 2026-10-09) — `render/app.js moveDragVisual`, `render/drag.js dragStandTile`
+- **Seen**: while an operator was dragged, the model was held under the pointer — its drawn (lifted) feet
+  `DRAG_HOLD_TILES` (0.45 tile, §18.1) of its own px per tile below the pointer, solved on the lifted plane (ground +
+  the 0.3 drag lift) — while the drop target, its highlight, `tileHover` and the direction wheel are the tile under the
+  pointer. On the prep camera the feet and the shadow landed about 0.7 tile toward the camera: on the tile below the
+  highlighted one (PR #403's screenshot). Measured on the parent in the mock: the pointer on (9,4) held the model at y
+  8.46–8.50 (mouse at 1920×1080, finger on the 844×390 phone), on (11,5) at y 9.98–10.50 (1600×900); in the Final
+  Assault prep about 0.7 tile off its target. PR #403 moved the pick to the feet instead. That breaks the standing rule
+  (§18.1: the tile under the pointer decides; restated by the owner on #138, §27.49), still misses by about 0.2 tile (it
+  samples the ground ray, the model is lifted) and fails models.browser #4.1, so the pick stays and only the drawing
+  changes.
+- **Official**: the owner's recording of the official game (2026-10-09; a deploy drag, the gesture 卫戍协议 shares, research
+  09 §1.2): while an operator is dragged onto the field its model is drawn standing on the tile under the touch point.
+  It does not float with the finger: the finger moving inside the tile leaves the model where it is, the touch point on
+  that tile at the model's feet or lower body; that tile is lit (with the attack-range stripes), takes the drop, and the
+  direction wheel opens on it. Over no deployable tile no model is shown on the field.
+- **Now**: `moveDragVisual` asks `dragStandTile(pieceDragMove)`, which returns the drop target while it is LEGAL and on
+  the board or the bench (`{ row, col, bench }`, board space); the unit's world x / y / z are then set to that tile at
+  once (no tween between tiles) through `boardWorld` — the point the drop tween goes to, with the Final Assault / Hidden
+  Core prep transform — and it keeps its drag lift. Otherwise — no target, an illegal tile, a temp slot, its own bench
+  slot, `'outside'` over the shop bar — it is held under the pointer as before, so the player still sees what they carry
+  (our pieces start on the bench, unlike the official hand card, so "no model off the field" is not taken). Item plates
+  are unchanged (centred on the pointer). The pick (`pickBoardTile`), the highlight, `tileHover`, the wheel and the drop
+  are untouched, and mouse and touch share the path (the phone uses the same tile pick). A drop from the snapped place
+  has nothing left to slide: the lift drops and the wheel opens on the tile. The DOM fallback field
+  (`ui/fallbackField.js`: a flat grid, its ghost centred on the pointer, so already on its tile) is unchanged.
+- [ASSUMED]: a legal bench slot is stood on like a board tile (the recording shows the field only); the 0.3 drag lift
+  stays while the unit stands (the recording does not settle a lift that small).
+- **Golden**: unchanged (presentation only).
+- **Tests**: test/render/drag.test.js (+2: `dragStandTile`'s decisions; a drag through the controller over its stubbed
+  tile pick, mouse and touch — one tile while the pointer moves inside it, the next legal tile at once, none on an
+  illegal tile, a temp slot, the own bench slot, the shop bar or off the grid, the drop on the tile stood on, a board
+  piece on its own tile). test/render/models.browser.test.js #4.1 drag (mouse) and touch (phone): over a legal tile the
+  unit stands on the pointer's tile (its x / y = the tile, on its top, lifted), at four spots of the tile without moving
+  on screen, at every step of a second leg (standing on the legal tiles, held under the pointer elsewhere), held under
+  the pointer / finger over the shop bar, standing on a free bench slot; the wheel on the pointer's tile as before.
+  test/render/fieldview.browser.test.js: in the Final Assault prep (both halves) the dragged unit stands on its target's
+  boss-field tile, mirrored on the right. Both browser extensions fail on the parent. test/docs-consistency.test.js (the
+  code calls `dragStandTile`, DESIGN and PLAYING describe it). Docs: docs/PLAYING.md §4, README.md,
+  docs/design/client.md §9 / §10, the app.js / drag.js / tune.js comments.
