   - The Front model replays the state: the Die clip where it would be (`dieT`), a knocked-down one holding its end; `die(true)` and a view built for a unit already down start on the held end (the 联防 entry `FORCED_EXIT`, a field entered late, the re-entry from the field meta after an overflowed hidden-tab backlog). Its first frame gets the knocked-down grey (`_dropActor` drops the cached tint; a swapped-in model used to keep the previous model's tint state). A withdrawn operator facing UP (no `down` entry) fades like one facing RIGHT: the Front model's Die clip times the fade (`_fallDur`).
   - The redeploy (a `deploy` event: timed, 不屈, 阿戈尔 — every `Battle._deploy` — or a revive seen only in the snapshot) brings the Back model back; a deploy clip the Front model is playing goes on on the Back model where it is (`SpineActor.deployElapsed`).
   - Safety net: until the Front model is there, or when it fails to load, the Back model holds still — `SpineActor.die()` on a skeleton without a Die clip stops whatever looped and holds the first frame of its idle clip (frozen when it has none either), and nothing restarts an attack on a dead actor. The 20 summon / enemy skeletons without a Die clip (e.g. 浊心斯卡蒂's 海嗣) now fade holding still instead of looping [ASSUMED look].
-  - Unchanged: operators facing RIGHT / DOWN / LEFT, enemies and summons (no Back models in the manifest: `_wantsBack` is false for them), the redeploy ring, the sim. Nothing changes in render/interp.js or battle/runner.js: `die` / `deploy` are state events every client stage keeps (runner `keepsState`, game.js `keepEarly`, interp `isCosmeticEvent`), and b.snap `down` / `fieldMeta` rebuild the view of an operator already down; both now reach the model swap.

 - [ASSUMED]: the Front model for the fall and the knocked-down pose (above); the Back skeleton's own Die clip when it has one; the held first idle frame of a skeleton without a Die clip.
