+- `Dumas H3 Long Videos`
-  - Inputs: H3 model stack, prompt socket, optional `first_frame`, optional `ref_1`..`ref_9`, plus the upstream long-video control surface for pacing, continuity, audio, overlays, and guards
+  - Inputs/outputs: the current upstream `MiniMax-H3-Longvideos` sampler surface, exposed under the existing `DumasH3LongVideos` key for saved Dumas workflows.
-  - Outputs: `images`, `audio`, `info`, `script`, `frames_per_shot`, `total_frames`, `shots`, `video_seconds`, `fps`, `fps_int`, `latent`, `soundscape`
+  - The local Dumas prompt-engineering fork has been removed from this node. Long Videos now wraps the upstream sampler/engine directly so it can track the source project again.
-  - First-pass Dumas port of the `MiniMax-H3-Longvideos` sampler, brought in as a local starting point for long-form H3 chaining work.
+  - Upstream compatibility keys `H3LongVideos`, `H3LongVideosFL2VA`, `H3LongVideosV1`, and `H3LongVideosREF2VA` are also registered to the same class.
-  - Keeps the upstream split-beats / handoff / ref-routing behavior close to source so future Dumas-specific improvements can be compared against a known baseline.
+  - The old Dumas browser widget grouping script is disabled for this node because it targeted controls that no longer exist on the upstream sampler.
-  - Full user guide: [`H3_LONG_VIDEOS_GUIDE.md`](./H3_LONG_VIDEOS_GUIDE.md)
+  - `handoff_frames` extends the upstream last-frame handoff: `1` keeps the current single keyframe behavior; higher values keep that final-frame keyframe and add earlier tail frames from the previous shot as claimed reference context for the next beat.
-  - Only the canonical `DumasH3LongVideos` node key is exposed now; the older FL2VA/REF2VA alias entries are no longer duplicated in the Add Node menu.
+  - Upstream license text is included in [`H3_LONGVIDEOS_UPSTREAM_LICENSE.txt`](./H3_LONGVIDEOS_UPSTREAM_LICENSE.txt).
-  - Prompt `<Picture N>` tags now map to the actual ref socket numbers you wire, even with gaps such as only `ref_2` and `ref_7` connected.
-  - Character refs now contribute appearance and wardrobe context from the same structured object, while location refs contribute environment context from theirs.
-  - The default ref2v bias is now stronger: `ref_mode` defaults to `auto ref2v` so untagged prompts condition every shot instead of only shot 1, and `ref_noise_aug` defaults to `0.95` rather than the upstream-literal `0.999`.
-  - `Dumas H3 Latent Upscale Params` provides the optional pre-decode latent refinement stage for the long-video node.
-  - Per-shot directives now support `continuity:`, `ref_mode:`, `ref_noise_aug:`, `anchor_add:`, `soundscape:`, and `music:` in addition to the existing timing and wardrobe directives.

 - `Dumas H3 Beat Prompt`
   - Inputs: authored through the custom front-end beat editor
   - Output: `prompt`
-  - Builds one H3 prompt block per beat, with quick controls for per-shot timing, continuity, ref behavior, anchor additions, soundscape, and music while staying compatible with direct text editing.
+  - Builds an upstream-compatible Long Videos prompt: optional scene paragraph, optional character sheet, then one blank-line-separated textbox per beat.
+  - Per-beat helpers only emit upstream-supported state directives: `remove:` / `removed:` / `off:` and `add:` / `wear:` / `wearing:`.
+  - Old Dumas-only beat directives such as `seconds:`, `continuity:`, `ref_mode:`, `ref_noise_aug:`, `anchor_add:`, `soundscape:`, and `music:` are stripped from the generated prompt so they are not sent to the upstream node as visible text.

   - Builds one standalone MiniMax H3 prompt from your final action text plus structured character/location references.
   - The action text can mention references by character/location name, alias, `<Picture N>`, or `<refN>`. Only mentioned references are emitted, and the output images are compacted/renumbered so skipped inputs do not leave gaps.
-  - Adds curated reference context, anatomy guard text, optional subject-count guard text, anchor/style text, and `overall_soundscape:` text while respecting MiniMax H3's reference-generation shape: one prompt plus up to nine reference images.
+  - Extra component outputs expose the cleaned anchor, sounds, BGM, and each selected original reference image plus its compiled reference description in compacted order.

 `Dumas H3 Plan Attach Scene Images` and `Dumas H3 Plan Extract Scene Images` are a companion pair for `ComfyUI-MiniMaxH3-Contex-Loop` and the local `ref2v` lane. The upstream H3 plan node cannot dynamically grow nine new image sockets for every JSON-defined scene, so Dumas stores scene image bindings beside the plan using a lightweight token and an in-memory registry. That keeps `plan.json` archiving intact while still letting you wire up nine IMAGE sockets per scene through chained helper nodes.
 
-`Dumas Character Helper` is the restored two-image/text helper for general H3 workflows, and `Dumas Location Helper` mirrors it for scene/environment references. The structured `Dumas Character Reference` and `Dumas Location Reference` nodes remain available separately for workflows that want a single `REFERENCE` socket. `Dumas H3 Prompt Curator` consumes those structured references, assigns the final `<Picture N>` numbering, and outputs only the compacted images the prompt actually mentions.
