feedback3 WF: the initial deployment goes by column — the left column first, top to bottom within a column (PRTS 从上到下>从左到右 read as a scan, the 阿戈尔 devour's order; mirrored boss side from its own left); a merge's elite among several deployed copies follows it (server and client); tests whose target was the latest deployed keep it

 | Moving a deployed unit | Drag the unit to any legal tile, **including its own tile**. The same diamond opens. The original stays visible until confirmed; cancelling leaves the unit and its facing unchanged. Re-orienting in place = drag the unit onto its own tile and swipe a new direction. | WIKI + ASSUMED (own-tile case) |
 | Tap a deployed unit | Opens the selection diamond (underframe) around the unit and shows its **attack range tiles** on the board (orange). Buttons on the diamond: **撤退** (red runner icon, upper-left; unit returns to the bench) and **出售 +1** (coin badge, upper-right). The left side shows the detail card: portrait, tier, LV, ATK/DEF/RES/block/cost, an "攻击范围" mini-grid, bond icons, and tabs 特质/技能/特性/天赋/装备. You cannot rotate from this menu. | DATA + WIKI |
 | Default facing | Every player-initiated placement goes through the wheel, so there is no silent default. Server-created board units (effects such as 外勤医疗 or 预备干员, bots, and back-compat) default to **RIGHT**, toward the gates. | ASSUMED |
-| Persistence | Facing is stored with the position and survives round changes. At combat start units auto-deploy on their tiles **with their facing**, in order **top→bottom, then left→right** (盟约下). | DATA (positions) + COMM (order) |
+| Persistence | Facing is stored with the position and survives round changes. At combat start units auto-deploy on their tiles **with their facing**, in order **从上到下>从左到右** (盟约下): down each column, the columns left to right (research 01 §4.3). | DATA (positions) + COMM (order) |
 | Melee, ranged, medic | All use the same wheel. The range preview uses the unit's own rangeGrid (heal range for medics). Blocking and "front" logic use the facing vector. | DATA |
 | Summons (tokens) | Each summon is its own bench card ("干员及其召唤物会自动加入整备区"), placed and moved freely with the same wheel. Retreating the owner also retreats its summons. | WIKI |
 | Equipment | Dragged onto a unit (board or bench). No direction step. A third item opens the equip-replace dialog (`UseEquipUp { charChessInstId, equipChessInstId, isChangeEquip, unloadInstId }`). | DATA |
