 ## This pass
 
-- Tightened the clip prompts so `<Picture 1>` carries the master scene and `<Picture 2>` carries the primary full-body identity, matching the current Ref2VA prompt hierarchy.
-- Kept the `clip_by_clip` validation flow and the `480p` / `3 x 10s` budget intact.
+- Promoted the Chris working quality lane into the maintained master.
+- Enabled the built-in `2 Pass` path.
+- Enabled the built-in `HIGH QUALITY` path so `RTXVideoSuperResolution` runs.
+- Swapped away from the Heretic text encoder to the `AWQ` MiniMax encoder path.
+- Kept the prompt structure generic and reusable for the single-clip `ref2v` lane.

 ## Main changes
 
-- keeps `clip_by_clip` validation instead of `full_batch`
-- keeps the safer `864x480` working canvas
-- keeps `5` steps rather than the source graph's more brittle `4`
-- expands the starter plan to `3 x 10s` clips so the default chain matches the
-  safer continuation cadence already established by the compact local MiniMax
-  masters
-- uses neutral reusable `R2V` prompts instead of a source-specific demo scene
-- keeps `context_length=22` and `ref_image_size=match`
+- keeps the safer `864x480` working canvas for the main `ref2v` lane
+- uses the `AWQ` MiniMax text encoder instead of the Heretic path
+- enables the graph's `2 Pass` lane
+- enables the graph's `HIGH QUALITY` lane so `RTXVideoSuperResolution` runs
+- sets the RTX upscale multiplier to `2x`
+- keeps `Sol Attn` enabled in the promoted working graph
+- keeps generic reusable prompt text in the single-clip lane
+- replaces the old Chris-specific continuation plan with a generic three-shot starter
 
-## Why this is the kept reference-first master
+## Current working settings
 
-- Chris's standing preference is `reference-to-video` first, so this workflow
-  is optimized around `Ref2VA` continuation instead of plain `t2v`
-- it is still the cleanest workflow for starting from reference images before
-  any imported-video continuation takes over
-- it inherits the safe local budget lessons from the earlier MiniMax loop and
-  extender experiments instead of pretending the source defaults are free
-- the newer same-day `javawock7618` `INT8 R2V` import is the strongest current
-  donor for tighter subject retention, so the maintained master now spells out
-  the scene/subject authority order more explicitly
-- this is the cleanest current merge of:
-  - better continuation workflow UX
-  - safer `3070 / 8 GB` assumptions
-  - `R2V`-first control
+- main `ref2v` resolution: `864x480`
+- source timeline basis: `24 fps`
+- main scheduler lane: `simple`
+- standard sampler option present: `euler_ancestral`
+- high-quality sampler option present: `euler_ancestral_cfg_pp`
+- second-pass denoise in the promoted working graph: `0.4`
+- starter continuation plan defaults: `10s` clips, `8` plan steps
+- RTX upscale: `2x`, `ULTRA`
 
 ## When to use this
 
 - use this first when the goal is: keep one or more reference images stable and
-  extend the action across several connected clips
+  generate a higher-quality `MiniMax H3` `ref2v` clip with the current quality
+  passes enabled
 - use `optimized/image-to-video/minimax-h3-extension-master/`
   instead when the main job is extending an already existing source video
   rather than generating a new reference-driven chain
 
 ## Notes
 
-- Start with one strong main reference and short clips.
-- Validate each clip before moving on.
-- Add extra image references only when they solve a real identity or scene
-  problem, because more references also increase fragility.
+- This master is now heavier than the older lightweight `w4a8` / Heretic lane.
+- It is the quality-biased `ref2v` path, not the cheapest local-safe path.
+- The graph still carries extra continuation machinery from the promoted Chris
+  working workflow, but the maintained `ref2v` lane is the generic single-clip
+  starter built around the reusable prompt block and quality passes.
