Michael Darius Eastwood, independent researcher, London: originator of the embedded-correction alignment thesis (manuscript 8 December 2024, SHA-256 anchored: f0d1f38f).
First appearance: U = I x R stated in the 8 December 2024 manuscript (Version 2, lines 6-9). Formalised as U = I x R^alpha in Paper I of the ARC/Eden paper suite. Current status: architecture-dependent alpha values measured on current frozen systems; the fixed-exponent framing as the operative safety criterion is superseded by Paper X's beta greater than k criterion. The equation and the ARC Bound remain live hypotheses; only the earlier unblinded single-model fit of alpha approximately 2.24 was retracted, corrected to approximately 0.49 under blinding.

Definition

The ARC (Artificial Recursive Creation) Principle states that effective capability (U) equals base intelligence (I) multiplied by recursive depth (R) raised to a scaling exponent alpha. Alpha is not a universal constant; it is determined by the composition operator of the specific system. For physical systems embedded in d-dimensional space, alpha = d/(d+1), which is always less than 1. For self-referential systems governed by a coupling parameter beta, alpha = 1/(1 - beta), which can exceed 1 when beta is positive. The principle predicts that sequential recursive processing yields super-linear gains for compatible architectures, while parallel processing yields sub-linear or flat gains.

Where it first appeared

The equation U = I x R appears in the 8 December 2024 manuscript at Version 2 lines 6-9, described as 'the core of the framework'. Papers I and II formalise this as U = I x R^alpha. The published book presents U = I x R^2 (the alpha equals 2 case) as the featured formulation. Paper X supersedes the fixed-exponent framing as the operative safety criterion and installs the beta greater than k co-scaling stability condition as the current operative quantitative claim. The equation itself was not retracted; only the earlier unblinded single-model fit of alpha approximately 2.24 was retracted, corrected to approximately 0.49 under blinding.

Independent convergences

The dimensional formula alpha = d/(d+1) has been independently derived by at least five research groups (West, Brown and Enquist; Banavar; Demetrius; Bettencourt; Zhao). The ARC framework unifies these under a Cauchy-functional-equations synthesis rather than claiming novelty for the exponent itself. Sharma and Chopra's sequential edge result (arXiv:2511.02309, 4 November 2025) precedes the programme's own January 2026 formalisation by approximately 2.5 months and is credited concurrent priority for the quantified finding.

Status and limits

The ARC Principle is measured at architecture-dependent alpha values on current frozen systems in Paper II and its sequel work. The initial universal-alpha-greater-than-1 claim from Paper I has been honestly revised: on the hard tier, alpha is often sub-linear, and the three-tier alignment hierarchy shows positive, flat, and negative scaling depending on model. The fixed-exponent framing as the operative safety criterion has been superseded by Paper X: the load-bearing operative quantitative claim is now the beta greater than k co-scaling criterion for stability. The ARC Bound alpha at most 2 remains a live hypothesis whose real domain, genuine self-improving systems, remains unmeasured; the beta over k programme is that test.
