simready-foundation-conform-fet-003-physx

SimReady Conform FET_003_PHYSX

Purpose

Use this exact feature skill when the selected profile, validation report, or user request names FET_003_PHYSX. It repairs or stages rigid body physics (physx) conformance without drifting into another runtime contract.

Default to FET_003_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.

Source of Truth

Before changing an asset or package, read:

• nv_core/tiers/simready_foundation_tier_core/simready/foundation/tier_core/features/FET_003_PHYSX.md

Treat the selected JSON manifest as authoritative for dependencies and requirement IDs. Use the feature markdown for human-readable contract details, requirement links, samples, benchmarks, and adapters.

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_prop_physx	FET_003_STANDARD@0.1.0 -> FET_003_PHYSX@0.1.0	Mesh extents on all meshes.

• The adapter runs on a staged output stage and never creates geometry; it only annotates existing prims. Ensure colliders/rigid bodies already exist.
• It reaches FET_003_PHYSX@0.1.0 only. The default @4 (and @2/@3) adds RB.* rigid-body and PHYSX.COL.001/PHYSX.COL.002 requirements that the adapter does not author; repair those manually per the Workflow below.

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_003_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_003_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_003_PHYSX version, changed files, validation evidence, and the first remaining blocker or next exact feature gate.

Feature Guidance

• Repair the selected PhysX rigid-body feature and use PhysX-only collider schema only when the manifest allows it.
• Keep multibody joint and articulation work in FET_004_PHYSX or related robot features.
• Record whether runtime or validator evidence was available for PhysX collider behavior.
