2b37cc8a5a136adc3dd5929ab7cc2a12be39f926 WebGPU: Do not store WGPURenderBundleEncoderDescriptor in RenderBundleEncoder and RenderBundle
not a security fix
confidence 0.18
signal score 9.77
Source/WebGPU/
Classified as not security-relevant.
Triage note: Stops holding a by-value WGPURenderBundleEncoderDescriptor (whose colorFormats pointer had to be fixed up to m_descriptorColorFormats) and instead stores owned scalar/vector members used by validateRenderBundle. Lifetime-hygiene refactor removing a pointer-carrying descriptor; old code already repointed colorFormats, so no concrete bug is evident.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
