Retro Diffusion style LoRAs — trigger-word reference

Local record of the RD style-LoRA trigger words, for reproducible ComfyUI ideation prompts without round-tripping to comfy-dev. Canonical source is catalog/loras.yaml on the ComfyUI box (irv-ml1); this is m03-dev's working copy (from comfy-dev, thread 01M01PKJ5EAR…, 2026-08-15).

Licensing (operator directive): these weights are copyrighted, licensed-for-use, not-for-export — fleet-internal only, no redistribution / publish / serve. Ideation OUTPUT stays _ph placeholder per the game asset policy. This file records trigger STRINGS (not weights), but treat the whole capability as internal.

How triggers work: prepend the trigger token to the prompt to activate the LoRA's trained style. Coverage = share of the LoRA's training captions that led with that token (higher = more reliable). Derived from each LoRA's kohya ss_tag_frequency.

Gotchas

• All three tiling* LoRAs share pixelmcblocks64 — the token does NOT encode tile size (the weights do). Do NOT substitute pixelmcblocks16/32.
• isometric / psone triggers disagree with their vendor stems (isopixel64-v2, psone64-v1). Caption token recorded here leads 100%; if either underperforms, try the stem form as a fallback.

For the U R M03 first batch

Likely-relevant: duelystchar (gamecharacters) and gamecharactersretro / gamecharactersanime (no trigger) for M03/grunt/burster sprites; frontfacing (pixelfurniture64 — note: furniture-trained, verify on a character) and topdown (pixelbuildings64) for camera; console-palette LoRAs (nes64, gameboy64, …) for the hi-bit palette exploration. Render at 512, downscale to 32/48px targets (model resolution floor).
