title	UET Topic 0.19: Gravity GR
description	Gravity constant, weak-field formula, and GR-bridge diagnostics within the Unity Equilibrium Theory framework.

0.19 Gravity & General Relativity

Note

AI-Digest: This topic currently has a CODATA gravitational-constant checkpoint and a reviewed weak-field formula registry. The primary artifact verifies that the engine constant package matches the local CODATA working copy; it does not yet derive Einstein's equations, validate light bending/perihelion precession, or solve singularities.

Research Role

Topic 0.19 is the gravity/GR bridge layer. Its immediate role is to keep constants, weak-field formulas, equivalence-principle diagnostics, and short-range gravity datasets auditable before any stronger theoretical claim is made. It is important for 0.0, 0.2, 0.3, 0.21, 0.23, and 0.26, but those topics must inherit its current limitations.

Evidence and Status Matrix

Layer	Current status	Evidence path	Claim allowed now	Blocker
Data	CODATA/Eot-Wash/MICROSCOPE working copies with source labels	Data/03_Research/*.json	Local constants and comparator datasets are inspectable.	Some source URLs/licenses and extraction notes still need normalization.
Formula	Reviewed registry	FORMULA_AUDIT.md	Constant package, Planck definitions, Newtonian/Schwarzschild diagnostics, eta, and Yukawa comparator are mapped.	Several theoretical bridges remain diagnostics or open lanes.
Verification	Runnable primary artifact	Code/03_Research/Research_G_Constant.py	Confirms engine G matches CODATA working copy under declared threshold.	This is a copied/source-constant checkpoint, not a derivation.
Source evidence workflow	Structured provenance gate	Data/03_Research/source_evidence_intake_stub.json, source_evidence_readiness_matrix.json	source-review queue	Weak-field, equivalence, and short-range packages still need dedicated artifacts.
Branch claim gate	Structured claim ceiling	Data/03_Research/branch_claim_gate.json	checkpoint-only claim control	Constant checkpoint does not promote GR closure claims.
Claim-scope gate	Artifact export controller	gravity_claim_scope_gate in artifact	blocks GR/quantum-gravity overclaim	Constant PASS remains topic-level WARN until physical GR tests and derivation artifacts exist.
Core GR program dependency	Candidate mathematics / blocked	CORE_GR_PROGRAM_DEPENDENCY_SPEC.md, Result/artifacts/0_19_core_gr_program_dependency_gate.json	exact implemented response-null, local balance, bounded causal/reduction statements	physical GR benchmarks, curved 3+1, EOS/transport, and global closure remain blocked
Claims	Bounded to internal checkpoint	this README, METHOD.md, LIMITATIONS.md	May state that the engine constant package is internally consistent with CODATA.	Cannot claim GR derivation, light-bending validation, or singularity avoidance.
Dependencies	High-impact core bridge	0.0, 0.2, 0.3, 0.21, 0.23, 0.26	Downstream topics may cite constants/weak-field formulas with limitations.	Strong GR/cosmology claims need future artifacts.

Primary Verification

python docs/topics/0.19_Gravity_GR/Code/03_Research/Research_G_Constant.py

Expected artifact:

• Result/artifacts/0_19_gravity_gr_verification.json

The artifact records dataset hash, CODATA DOI, formula IDs, threshold, engine G, and Planck-unit metrics.

Core GR program dependency (candidate mathematics)

• Contract: CORE_GR_PROGRAM_DEPENDENCY_SPEC.md
• Runner: Research_Core_GR_Program_Dependency_Gate.py
• Artifact: 0_19_core_gr_program_dependency_gate.json
• Result: BLOCKED / CORE_CANDIDATE_GR_PARENT_AVAILABLE_TOPIC_PHYSICAL_VALIDATION_OPEN.
• Accepted scope: the implemented epsilon_nc = 0 branch has an exact response-null; the candidate parent has a local exchange-balance identity; the constitutive causal result is restricted to a flat local 1+1 lane; the response reduction is partial.
• Preserved boundary: the primary Topic 0.19 artifact remains a Claim Class C CODATA/Planck checkpoint with export controller WARN.
• Open controller: source-backed light bending, perihelion, MICROSCOPE eta, Eot-Wash, curved 3+1, EOS/coarse-graining/transport/KMS, entropy-current, and holdout comparison are still missing.
• Global statement: universe closure remains UNRESOLVED; epsilon_nc is a nesting coupling, not an openness percentage.
• Status impact: none. Topic 0.19 remains Draft / Tier B.
