Avatar and animation acts

Who it's for. You draw the NPC in Web or Roblox. Cosmetics are not the trained brain.

What you'll do. Apply equipped SKU / avatar_style at spawn, then play clips by priority: game events, Hub overlay, locomotion, idle.

Cosmetics and clips are not the brain. The MLP outputs move / jump / fire. The game draws the body and runs an AnimationDirector.

Apply look at spawn

Read session or play-config: equipped character / skin / anim SKUs plus Roblox description ids or wardrobe_id. Fallback: avatar_style (my_avatar, classic_male, classic_female, robot).
Roblox: Clone wardrobe or ApplyDescription; cache the NPC template. Web: load GLB/skin on the canonical rig. Do not HttpService-download a Hub FBX as a Humanoid.
If a clip or id fails, fall back to GymFx / default gait. Do not stall spawn.
Never put sku_id into observations or policy_steps.

AnimationDirector (priority high to low)

Priority	Source	Example acts
4	Game events (Died, finish, contest bump)	Die, Win, Bump
3	Hub overlay (/play/act anim or director)	Panic, Block
2	Local locomotion (Humanoid or sim)	Walk, Jump, Fall
1	Idle	Idle

Locomotion clips always start from local physics. Do not wait on HTTP to play Jump.
Overlay Panic must not raise WalkSpeed (tsunami panic is animation only).
The MLP never selects Win — the game fires finish/death events.
Missing optional clips (Panic) skip overlay rather than error.

Roblox vs web today

Campus Roblox uses R15 from the owner’s userId plus style tint, and GymFx catalog walk/jump/fall. Web tsunami uses cartoon LeaderAvatar and resolveGait (jog, panic, lip, air). Hub-managed catalog SKUs add JSON ids on top of that; binaries stay on Roblox CDN or in the place wardrobe, and GLB on a web CDN for catalog/web play only.
