Enchan Field Notes (Theoretical Framework)

Current version: v0.4.5 Status: theoretical note + public-data benchmark package License: Apache License 2.0 (see LICENSE)

Enchan Field Notes is a set of theoretical memoranda exploring whether several galaxy-scale regularities can be organized within an effective field description built around a dimensionless scalar S.

This repository includes:

• a LaTeX/PDF note (main.pdf, sections/)
• a small reproducibility package for public-data benchmarks (enchan-theory-verification/)

This work is not peer-reviewed. It does not claim to falsify particle dark matter.

Scope (v0.4.5)

v0.4.5 is a copyedited, minimal-scope release intended for external distribution.

• The PDF focuses on definitions, effective equations, and galaxy-scale benchmark targets.
• Implementation details, device concepts, project planning, and forward roadmaps are intentionally out of scope.

---

Benchmarks (public-data targets)

The reproducibility package defines and evaluates externally checkable targets commonly used in the literature:

1. RAR / MDAR (multi-point relation)
2. BTFR (one galaxy = one point)
3. Rotation-curve shape stress test (fixed-rule prediction, no per-galaxy tuning)

These are used as regression targets. They are not, by themselves, evidence of a unique underlying theory.

---

Baseline closure (benchmark interface)

Some scripts use a compact empirical mapping as a benchmark interface (baseline-only):

[ g_{\mathrm{tot}} = \sqrt{g_{\mathrm{bar}}^2 + a_0,g_{\mathrm{bar}}} ]

This should be read as reproducibility of the benchmark interface, not as a completed derivation from a unique fundamental model.

What's new in v0.4.5

• Editorial / scope tightening: removed nonessential narrative and non-public operational details from the TeX/PDF.
• Consistency pass: unified notation and kept the field description in a minimal effective form.
• Benchmarks kept explicit: benchmark definitions remain as externally checkable targets for later forward modeling.
