DON Emergent Gravity — 3D Collapse Proof & P2 Validation Suite

What this shows

• Collapse-only μ,J transport (no Poisson, no 1/r² coded) yields |J(r)| ∝ r⁻² in 3D.
• A test particle under the DON readout orbits with small energy and angular-momentum drift.
• P2 — Universality & Slip: Complete referee-ready validation suite with scale-dependent lensing/dynamics slip analysis using real KiDS W1 cluster data.

2) Orbit (conservative readout)
bash
Copy code
python src/don_emergent_collapse_3d.py --test orbit \
  --N 192 --L 80 --sigma 1.0 --tau 0.20 \
  --dt 0.025 --warm 8000 --steps 16000 \

Notes
The solver evolves collapse-only μ,J dynamics; no Poisson / 1/r² is hard-coded.

Optional flags:

--project_curl_free : one-shot Helmholtz projection of J for polished slope/fit.

--orbit_from_potential : use a = −∇(κ c² μ) for a conservative, central force orbit.
