Ten seconds, one fade down/up, 36-degree eased turn ending at +18 degrees, final light on. No additional spill light. Model units remain metres, Adom Z-up; source physical geometry is unchanged. Initial/static frame is lit. Use static downloads for engineering assemblies.++[Base geometry and optical assumptions](LED-STATES.md). The source remains a generic KiCad LED; these changes do not establish exact manufacturer package fidelity or electrical/thermal qualification.++## Skills audit++Reviewed current wiki-component, wiki-publish-safely, wiki-hero, adom-lbr-component-fidelity and chip-thumbnailer guidance. Corrected descriptive title in both manifests, manufacturer metadata, generic prose, explicit asset bindings and one-play viewer configuration. Preserved source files and licenses.++Remaining: manufacturer-qualified body/polarity comparison, full symbol/footprint/native-tool parity, annotated footprint artwork and shared outline/LOD caches have not been established by this hero repair. The original GLB is explicitly rejected as a resistor representation. No claim that every component-creation acceptance criterion has passed.

Replay is optional. The MPN is an AI-added visual identification overlay, not factory marking. The single embedded spotlight is illustrative, not calibrated photometry.++**Correction:** the original `ncd0402b1.glb` contains a mesh named `R_0402_1005Metric`, a resistor model, and is not a valid LED representation. It is retained only for history; do not use it. The original STEP remains unverified. The replacement is based on generic KiCad LED_0402_1005Metric geometry with retained upstream licensing, not a manufacturer-qualified package model. Exact body, terminal and polarity fidelity still require manufacturer drawing comparison.++Use the static [lit GLB](ncd0402b1-mpn-led-on.glb) or [unlit GLB](ncd0402b1-mpn-led-off.glb) for board assemblies; the [hero GLB](ncd0402b1-hero.glb) is presentation-only.
