SimReady Conform FET004ROBOTPHYSX

Purpose

Use this exact feature skill when the selected profile, validation report, or user request names FET_004_ROBOT_PHYSX. It repairs or stages simulate multi-body physics (robot physx) conformance without drifting into another runtime contract.

Default to FET_004_ROBOT_PHYSX@0.4.0 when the user asks for this feature without a version. Use an older integer version only when the profile, validation report, or user explicitly pins it. If the report names a different FET_###_RUNTIME feature, switch to that feature's matching skill before editing.

Feature Adapter

When the input already conforms to the neutral base feature, prefer the deterministic feature adapter to author the runtime-specific data first (via the workspace upgrade command; see nv_core/sr_specs/docs/guides/feature_adapters/feature_adapters.md), then repair only the residual requirements below.

Adapter module	Adapter	Transition	Authors
nv_core/cip_specs/asset_handler_modules/neutral_to_physx	rigid_body_neutral_to_robot_physx	FET_003_STANDARD@0.1.0 -> FET_004_ROBOT_PHYSX@0.2.0	Mesh extents on all meshes.

• The adapter runs on a staged output stage and never creates geometry, joints, or articulation topology; it only annotates existing prims.
• It only authors mesh extents (targeting @2). The robot RB.*, JT.*, RB.MB.001, and PHYSX.COL.* requirements — and the @4 default — must be repaired manually per the Workflow below on existing robot link/joint topology.

Workflow

1. Confirm the input exists and identify the exact selected feature/version from the profile TOML, validation report, or user request.
2. Load the selected FET_004_ROBOT_PHYSX manifest and the feature markdown before editing.
3. Load requirement docs linked from the feature markdown for every reported failing requirement.
4. Create or use a staged output location unless the user explicitly asks for in-place edits.
5. Repair only the requirements listed by the selected FET_004_ROBOT_PHYSX manifest and its dependencies.
6. Rerun the same profile gate or the narrowest available feature/capability validation gate. If runtime evidence is required and unavailable, report that limitation instead of claiming a pass.
7. Summarize the selected FET_004_ROBOT_PHYSX version, changed files, validation evidence, and the first remaining blocker or next exact feature gate.

Feature Guidance

• Use this legacy robot PhysX feature only when the profile pins it or needs its robot-specific collider exemption.
• Preserve robot link and joint semantics; leave robot identity to FET_021_* and driven actuation to FET_022_*.
• Do not create new geometry to satisfy this feature.
