An i2v model shown a sharp reference can satisfy the objective by barely moving. ALG low-passes the anchor while sigma is high, removing the detail that shortcut needs, and hands the sharp one back once the picture settles. It attaches to the model, so it applies to whatever sampler is wired, and it requires temporal_latent and nothing else -- not "for LTX", not "for H3". Any model with a time axis and a pinned anchor gets it, including ones nobody here has heard of. A module with no ComfyUI node of its own: settings and behaviour, which is what most modules should be. The packed-layout path is NOT ported. v4 reached into a model-specific arrangement of the latent to find the video stream; where the anchor is not a plain [B, C, T, H, W] tensor this stands aside and says so once, rather than reshaping something it is guessing about. Tested as far as a machine with no GPU can: the filter really low-passes, only the anchor frame changes, the choice follows sigma, and the whole thing runs through ComfyUI's real KSAMPLER with only the innermost loop stubbed -- so the anchor a denoiser sees differs between an early step and a late one. Whether it looks better needs the rental. Also guarded route registration. PromptServer.instance only exists once a server has been built, and importing `server` successfully is not the same as running inside one -- with ComfyUI on the path the unguarded attribute took the whole pack down.
