+# LTX 2.3 3070 Simple Master
+
+## Summary
+
+Best current `LTX 2.3` low-complexity starter for local video work.
+
+This master uses the simple single-pass workflow instead of the more ambitious first-last-frame or character-sheet variants because your `3070` needs a realistic first foothold, not the fanciest graph on paper.
+
+## Status
+
+- `best-current`
+- `not-yet-tested-on-chris-box`
+
+## Workflow asset
+
+- `workflow.json`
+
+## Built from
+
+- `models/ltx/ltx23-i2v-t2v-simple-single-pass/`
+
+## Why this is the current master
+
+- Most plausible `LTX` starting point on tighter VRAM
+- Simpler graph means less time chasing broken helper nodes
+- Supports both `image-to-video` and `text-to-video` style experimentation from one baseline
+
+## What I intentionally kept
+
+- single-pass graph shape
+- split-model assumption from the source pack
+- lighter starting complexity than the bigger RuneXX graphs
+
+## What I intentionally did not add yet
+
+- first-last-frame complexity
+- character-sheet consistency branches
+- extra memory-efficiency gadgets unless needed
+
+## Required custom nodes
+
+- `ComfyUI-KJNodes`
+- `rgthree-comfy`
+- `easy use` / `easy showAnything`
+- optional `ComfyUI-GGUF` support remains present in the source graph
+
+## Monday test checklist
+
+- Confirm whether it loads at all on the `3070`.
+- Check whether preview/decode settings feel like the real bottleneck.
+- If it works, then try the heavier first-last-frame workflow second.
+
+## Next optimization candidates
+
+- strip unused optional loader paths if they create confusion
+- create a separate `first-last-frame` master only if the simple master proves viable
