Introduction

1 / 3

Halo-Profile Inference Twin is a digital twin specification derived from principle L1-912. It defines the forward operator and a 3-dimensional parameter space Ω over which benchmarks are seeded. Each benchmark drawn from this twin is a concrete measurement instance with fixed Ω values; solvers must invert that specific measurement.

Derived from L1 L1-912 Dark Matter — Galactic Rotation & Halo Profile

Ω Parameter Space — 3 dimensions

halo: NFW|Burkert|MOND v_flat_kms: 50–300 concentration: 3–30

Prompt — copy into your LLM

You are helping me submit a MODIFICATION of L2-912 (Halo-Profile Inference Twin) to the PWM Protocol — a Digital Twin (L2) artifact.

I will paste a Markdown template (or the current L2-912.md).
1. Rewrite the Markdown so the science is correct and clearly explained for my change.
2. Regenerate the sibling L2-912.json so EVERY field matches the Markdown.
3. Keep the schema in the "File Mapping" footer at the bottom of the MD.
4. Keep the parent reference unchanged unless I ask otherwise.
Rules: the Markdown is the source of truth; use SI units; do NOT invent benchmark scores.
Output each file in its own fenced code block tagged with the filename.
