E560 — Duncan Fewkes reel analysis digest

Source video: `../reels/E560-DVlh0gSCiZ9.mp4` (symlink to `[home-path]`) Caption: `../reels/E560-DVlh0gSCiZ9.txt` This file aggregates every playbook chunk section that cites E560. Sections are de-duplicated by heading. - 20 reels ingested at `[home]/.openclaw/browser/reels-ingest/{DU,DV}*/` - Episodes covered: **E485 (Pt2 Jason Derulo World Tour), E525-E536, E543-E549, E556-E557, E560, E567-E568, E570** - 5 Gemini visual analyses: DU-52fcinww (E544 Blocky Pinscreen), DUleGWZisrH (E534 Fluid Presets), DV6A04wislr (E568 SuperHot Cubes), DUSui7PioUD (E527 Holovis branded), DUgoDHlipPu (E532 Depth Cubes vs Fluid Presets) — rest rate-limited - All on **HDRP + VFX Graph + Shader Graph** (confirmed every caption) E560 caption — found by accident, kept: > *"Stopped Unity editor playback and the fluid sim stops updating but the buffers don't get cleared (as they exist in asset database), so the particle VFX continue to update and the particles follow the frozen sim velocity buffer paths. This creates frozen forms in the motion paths that you don't get while the sim is updating."* This is **distinct from SuperHot mode**: SuperHot pauses sim time when user is still; this is **freezing the velocity field while the particles keep flowing through it**. The result is laminar streams flowing along etched-in paths. Implement as another mode on the LumeMotionGatedFluidSim controller: `FreezeVelocityField` toggle.
