Research direction

Start by reproducing the report with torch 2.4.1+cu124 on an 8 GB RTX 2070 using flux_fill_outpaint with KSampler, KSamplerAdvanced, and SamplerCustomAdvanced across the reported samplers and schedulers. Trace when latent noise changes between steps; done means the latent noise is not randomly reset during fill-model sampling.
