[Legacy] H3 Continuum Session Info

H3 Continuum Session Info is the diagnostic-and-bridge node for the V2 session system. Give it a session (loaded via Load Session or passed out of a H3 Continuum Sampler V2) and it does two things: exposes a report so you can see what's actually in the session, and - the part that makes it interesting - extracts the session's final V1-compatible continuation state.

Inputs: session. Outputs: session (passed through), last_state (an H3_CONTINUUM_STATE), and report (STRING, readable via Core Preview as Text).

The "V1-compatible" bit is the historical glue. V1's continuation chain (Join → sample → Finish) consumed H3_CONTINUUM_STATE objects, while V2 moved to sessions that bundle accepted chunk latents plus metadata. Session Info bridges the two generations: if you have a V2 session and want to continue it through V1-style nodes - or you just want the final state to hand to a Save State node - this converts the session's endpoint into the state format the V1 machinery understands. It's how the pack kept old workflows alive across its own API changes.

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+.

Honestly, you'll rarely add this node to a new graph. Its two real uses are troubleshooting ("what exactly is in this session, and is my last_state where I think it is?") and mixing V1 and V2 machinery in an older workflow. If you're on the modern V3.3 path, session and state are handled inside the sampler plus its Run Storage - no Session Info, no manual conversion. It's a legacy utility that earns its keep only when you're working with workflow files that predate the integrated design.
