[Legacy] H3 Continuum Load State

H3 Continuum Load State loads a saved continuation state back from disk so a run can resume or be extended in a later session. It's the read side of Save State: give it the same prefix and slot, and it returns the H3_CONTINUUM_STATE plus a path STRING for the source file.

The state is the pack's raw audio/video latent context - everything the next chunk needs to continue the scene without restarting from a keyframe. You feed the loaded state into a sampler's initial_state input (V2 and earlier generations) or into a V1 Join as previous_state, and the next generation proceeds as if the last one had just finished. This is how you close ComfyUI overnight and pick a multi-minute video back up the next day instead of re-rolling all of it.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/ukr8b3g-cmyk/ComfyUI-H3-Continuum.git

or via ComfyUI Manager ("H3 Continuum"), then restart. No extra pip packages; needs a MiniMax H3 ComfyUI environment (weights not bundled) and ComfyUI v0.32.0+.

The practical caveat is the same one that applies to all latent-state resume: compatibility. A saved state was produced under a specific MODEL, resolution, and VAE setup - if you've changed the H3 checkpoint or canvas size since saving, feeding that state back in can produce garbage or fail the pack's strict-compatibility checks. For long interrupted runs, the modern samplers' run_storage = Save + Auto Resume is the better default because it verifies chunk compatibility (size + SHA-256) before reuse and only reuses what's actually compatible. Load State is the explicit, version-pinned alternative - fine for archiving a checkpoint-specific continuation, less forgiving of environment drift.
