MiniMax H3 Creator Artifact Retention Plan / 候选保留与拟删除清单 (Advanced/T8)

In a normal video pipeline, "clean up the rejects" means deleting files. In the T8mars H3 pack, it means generating a proposal and making you look at it first. MiniMaxH3CreatorRetentionPlanT8Advanced compiles each shot's retention policy against your explicit run receipts and emits a keep manifest and a proposed-delete manifest - two lists, one JSON each, zero filesystem access. The name is the honest one: it plans retention, it does not act on it. This is the pack's anti-footgun philosophy doing its most visible work.

Where it fits

It sits at the end of the Creator Workspace chain: Workspace → Shot Select → sampling → Run Receipt (which logs what actually happened per candidate) → this node. Feed it the workspace and, optionally, the ledger of run receipts. Each shot's retention_policy (set on its Shot Override) is then cross-checked against the receipts - accepted candidates go on the keep list, rejected/cancelled ones show up as proposed for deletion, and anything without a receipt gets flagged rather than guessed.

Inputs that matter

• workspace - required, the H3_T8_CREATOR_WORKSPACE.
• confirm_artifact_paths_reviewed - the gate. Default false, which means the node stays in "not ready" mode. You flip it once you've eyeballed the artifact paths. This is intentional: the plan refuses to look finished until you say you've looked.
• ledger - optional, from your Run Receipt chain. Without receipts, there's no evidence, and the plan says so.

Outputs

retention_plan (the typed object), status (whether it's ready or abstaining), keep_manifest_json and proposed_delete_manifest_json (the two lists), summary, and report_json for the audit trail. If you want to actually free disk space, that's a separate quarantine node in the pack - and even it only moves files into output/MiniMaxH3/creator_quarantine after a SHA-256 check, with explicit confirmation, never a permanent delete.

Installing it

Part of MiniMax H3 Audio T8 (T8mars/T8star, GPL-3.0). Manager search MiniMax H3 Audio T8, or:

cd ComfyUI/custom_nodes
git clone https://github.com/T8mars/comfyui-minimax-h3-audio-T8

restart. No mandatory pip extras; H3 weights and friends go in models/ by hand. H3 weights are under the MiniMax H3 Community License - the US, EU, UK and South Korea are outside its Applicable Territory.

The two things that trip people up

First, "it never touches the filesystem" is a feature, not a bug - if you expected a cleanup node that cleans, you've found the wrong node. The proposed-delete list is the deliverable. Second, confirm_artifact_paths_reviewed exists to annoy you into reading paths before you trust the lists; if status won't leave its hold state, that's the flag to check. And if a shot you know you rejected isn't on the proposed-delete list, the answer is almost always a missing ledger connection - no receipt, no evidence, no list entry.
