   - Outputs: `plan`, `image1`..`image9`, `connected_images`
   - Reads back the nine optional images for a selected MiniMax H3 plan scene, for example by connecting the current `clip_index`.
 
+- `Dumas H3 Long Videos (FL2VA + REF2VA)`
+  - Inputs: H3 model stack, prompt socket, optional `first_frame`, optional `ref_image_1`..`ref_image_4`, plus the upstream long-video control surface for pacing, continuity, audio, overlays, and guards
+  - Outputs: `images`, `audio`, `info`, `script`, `frames_per_shot`, `total_frames`, `shots`, `video_seconds`, `fps`, `fps_int`, `latent`, `soundscape`
+  - First-pass Dumas port of the `MiniMax-H3-Longvideos` sampler, brought in as a local starting point for long-form H3 chaining work.
+  - Keeps the upstream split-beats / handoff / ref-routing behavior close to source so future Dumas-specific improvements can be compared against a known baseline.
+
+- `Dumas H3 Shot Length`
+  - Inputs: `shot_seconds`, `fps`, optional `cap_to_h3_max`
+  - Outputs: `seconds`, `frames`, `info`
+  - Emits one H3-safe shot length as both seconds and a grid-aligned frame count for wiring into the long-video sampler and preview helpers.
+
+- `Dumas H3 Model Inspector`
+  - Input: `model`
+  - Outputs: `format`, `report`
+  - Reports the detected H3 base precision / quant format and the relevant compute-capability hints for the current card.
+
 - `Dumas Character Helper`
   - Inputs: `image1`, `image2`, `image1_picture_id`, `image2_picture_id`, `character_id`, `name`, `alias`, `gender`, `age`, `nationality`, `occupation`, `height_feet`, `height_inches`, `accent`, `general`
   - Outputs: `image1`, `image2`, `character_text`
