feedback2: WF review — the 高台 reading marked [ASSUMED] in the code comments; only 歌蕾蒂娅 is obtainable (崖心 / 见行者 are hidden chess); §22.6 notes the tile-based 地面干员 effects

 - **Cause**: build-data copied position MELEE and nothing read 可以放置于远程位; `board.js positionClass` mapped MELEE to 'melee' (melee tiles only), so `PlayerState._legal` refused the 高台 (`g.move` → `BAD_TILE`), and the client mirror (`gameLogic.js piecePosition` / `tileAllows`) agreed.
 - **Now**: build-data sets `placement: 'all'` on a chess whose branch trait without module (`branchTraitText`: the trait candidate's text, else the description) contains 可以放置于远程位 — exactly 崖心, 见行者 and 歌蕾蒂娅, normal and elite (6 records, the only data change; `validateAll` allows it on a MELEE record only; module-only text never counts). `positionClass` returns 'all' for them, so the server takes them on every deployable tile — `g.move`, swaps, a merge's elite (`mergeTile`), the terrain re-check (`_evictIllegal`), invariants and audit —, and the client's `piecePosition` 'ALL' lights the 高台 while dragging; every other melee unit keeps the refusal and its text. The battle keeps position MELEE: on a ground tile they block as before; on a 高台 (`unit.ground` false) they block nothing and attack from there — the sim needed no change (act2 m01, one 萨卡兹枯朽前锋 on the lower lane, 40 s: 歌蕾蒂娅 on (10,4) facing it 2 hits, no block, on (9,5) 12 hits, blocking; 崖心 and 见行者 alike; no errors).
 - **Bots** read the record's own position (`basePositionClass`): they still count these units as blockers (`isBlocker`; with the widened class they would not, and on act2 m01 the planner put 歌蕾蒂娅 and 崖心 on the 高台 as non-blockers, leaving 见行者 the only blocker on the road) and plan them on the ground tiles, as in 0.1.1 [ASSUMED]: offered the 高台, the planner still chose road tiles in the cases measured, but the lineup's blocker count assumes they block and a greedy 高台 pick could take a ranged dealer's tile — not benchmarked. `tools/balance.mjs` uses the same blocker test. Tokens are unchanged; the sim's automatic placements (the 突袭 landing tile, summon / device tiles) still treat them as melee, ground tiles only [ASSUMED].
-- **Players notice**: 歌蕾蒂娅, 崖心 and 见行者 can be dragged onto a 高台 (PLAYING §4); there they attack but block nothing.
+- **Players notice**: 歌蕾蒂娅 can be dragged onto a 高台 (PLAYING §4); there she attacks but blocks nothing. 崖心 and 见行者 get the same rule but are hidden chess this season (`isHidden`, never in the pool, the shop or a 突变细胞 roll), so only 歌蕾蒂娅 is reachable in play; 见行者's elite PUS-X refund (half the DP of a redeploy onto a ranged tile, kits/tier3.js `!unit.ground`) is therefore moot.
+- On a 高台 she is not a 地面干员 for the effects that read the tile (`unit.ground`: the 战栗维式重锤 proc, 休谟斯 回收利用, 不屈, the 只攻击地面单位 enemy, 污染秽蚀's 高地 rate), like a ranged operator up there; position-based effects keep her 近战 (精准 tier 2, 诗怀雅's talent) [ASSUMED: the official texts may mean the position class by 地面干员].
 - Normative lines rewritten with it: §3 (placement), §6.6 (the bot); research 03 C2; DATA §2 (`placement`).
 - Tests: `test/match/feedback1-placement.test.js` (#32-4: the data rule, cross-checked against character_table when the cache exists; `g.move` onto (10,4) / (11,4) / (12,4) of 战场#01(下半) for the six records; a 重装 refused with its text; ranged unchanged; client highlights = the server's tiles; swaps; the merge's elite on the 高台; the battle input and the sim on / off the 高台; bots), `test/match/board.test.js` (`positionClass` / `basePositionClass`), `test/ui/gameLogic.test.js` (the client mirror).
