feedback5: 乌尔比安 knocked out while his S3 has moved him lies and redeploys on his deployment tile, not on the anchor tile — the owner's decision of 2026-10-07 on community report 28 「乌尔比安3技能期间死亡会留在3技能位移后的位置复活，应回到初始部署位复活」, a deliberate deviation from PRTS's "where it fell" for this 【移动】 only; golden: unchanged (the corpus moves him 23 times and knocks him out 6 times, never while moved)

- server/sim/units.js `downAtHome` (false), cleared by every deployment (battle/deploy.js _deploy).
- kits/ops/chess_char_5_05-ulpia.js sets it once the S3 【移动】 has put him on the anchor tile; onEnd clears it when the
  skill ends with him standing (the 【返回】); knocked out, it stays for the body.
- sim/battle/tiles.js _layBody: a unit holding it lies on its home tile (his board placement, where the 从不混淆的方向
  stood) when that tile is in the rect and free — else where it fell [ASSUMED], the PRTS exception's one attempt; the
  timed redeploy, 不屈's and CB1's 复活 (M3茧甲 / 埃芒加德: at once, free) all come back there (restTile), b.snap
  `down` names it. Every other moved operator (a 突袭 jump, other kits' 【移动】) keeps "where it fell".
- Test: test/sim/feedback5-ulpia-revive-home.test.js (3) — knocked out during S3 he lies at home, the anchor tile free,
  and redeploys there; revived at home by M3茧甲; control: after the 【返回】 and for a 突袭 member the PRTS rule holds. The
  first two fail on the parent (he lay and stood up on (10,7)); the third fails there only on the missing field.
- Docs: DESIGN §25.17.3 (the decision, marked as the owner's deviation; the §25 intro's decisions of 2026-10-07),
  docs/SIM.md §1, DESIGN §5 (design/engine.md DP / knocked-out line), docs/PLAYING.md 作战 row.

Gate: non-browser suites 5024 / 5024, npm run golden ok, test/golden.test.js 9 / 9, lint 0 errors, check:imports ok,
typecheck ok.
