feedback5 WY: flying units hover 1.3 tiles (the client's 0.35 ÷ the standard prefab scale 0.27); the 帝国炮火先兆者 pair is drawn 1.263× taller and 木制瑞印 mirrored, as their official prefabs (from PR #211 by @xcdoge; the owner's decision of 2026-10-06)

Ported by hand from PR #211 by @xcdoge:
- render/units.js: FLY_HOVER 0.32 → 1.3, flat (the official fly offset is one model-independent Vector3(0, 0.35, 0) in
  the client's character space, whose unit is the standard battle-prefab scale 0.27; an official screenshot measures
  1.2–1.4 tiles); enemyModelScaleY multiplies the skeleton's Y scale and the head (bar) height, also in the impostor
  path; a mirrorX model flips on top of the direction flip. The body, its HP bar, damage numbers, projectile hits and
  skill rings ride `hover`, the shadow stays on the ground; one camera drives the units over the 2D and the 3D board.
- tools/build-data.mjs MODEL_STRETCH_Y / MIRRORED_PREFABS → enemies.json modelScaleY / mirrorX; data/enemies.json
  regenerated offline here (the PR's one-line blob was not taken) — JSON compare: only enemy_1112_emppnt /
  enemy_1112_emppnt_2 modelScaleY 1.263 and enemy_1196_msfyin mirrorX true.
- tools/local-extract/enemy_model_offsets.py (optional, host-side prefab reader) and
  docs/research/12-flying-visuals-official.md (without the claim that the owner said 「都要」 on 2026-10-05 — the owner's
  decision of 2026-10-06 is cited; where the quirk enemies appear corrected against 0.2.0's data: 帝国炮火先兆者 is a FLY
  special enemy of the mode, 帝国炮火中枢先兆者 comes with the bounty 战术特训·飞行III, 木制瑞印 is in no wave). No
  screenshot or extracted art committed.

Tests (from PR #211): test/render/unitview.test.js (FLY_HOVER ≈ 0.35 / 0.27; the same lift for every flyer; a flying
view lifts by FLY_HOVER — added here: its body and HP bar ride the lift, its shadow stays on the ground),
test/render/playtest6-enemies.test.js (the data keys; the 1.263 aspect and bar height; the mirrored model's x sign);
both fail without the renderer change; the 425 render unit tests pass. Docs: DATA §9, ASSETS, design client.md,
research 00 / 12, DESIGN §25.13.5 and the §25.10 table.
Golden unchanged (drawing only; the sim reads neither field).

An unblocked ranged enemy stands for this clip at each attack (sim/ai.js `attackStand`, GitHub #58), and every enemy attack strikes at `hit` after its swing starts — a stun before it cuts the swing (sim/ai.js `attackWindup`, 0.2.0). 213 keys; absent = no attack clip known (御4, 寒霜, the 岁 relics …: the sim keeps `ATTACK_PAUSE`).
