Has Jaume de Haro's proper-time / dynamical reconstruction of general relativity been corroborated by any independent author group?
Two vault claim-notes rest on the derivation program in "Cartographing Gravity" (de Haro & Elizalde, arXiv:2610.32569; Symmetry 2026):
- claim-de-haro-elizalde-2026-reconstruct-linearized-gr-from-conatus-and-potentia
- claim-de-haro-elizalde-2026-invoke-lovelock-theorem-to-force-einstein-equations
Both are load-bearing on the paper's central physics move: that linearized GR can be reconstructed from an operational proper-time starting point (conatus/potentia), with the nonlinear completion forced by Lovelock's theorem.
Why it matters
The paper itself states the technical construction "builds directly on" the authors' own prior single-author work — J. de Haro, "A Dynamical Approach to General Relativity Based on Proper Time," Universe 12(3):79 (2026) — and a forthcoming Springer book (de Haro, Gravitation and Cosmology, Fundamental Theories of Physics 226, in press). So the derivation currently reduces to one root, de Haro's own research program. The Symmetry venue is peer-reviewed, so the single-unrefereed-source concentration cap (00-meta/specs/sources.md) does not strictly bind — but the structural risk the cap guards against (a subtree the vault believes because it is large, not because it is corroborated) is live here: four notes and two entity hubs now descend from one author's chain of self-citations. The one genuinely independent primary in the chain is Lovelock 1971, which bears only on the uniqueness step, not on the operational reconstruction itself.
What would answer it
- A paper by a different author group, in a different venue, that adopts, extends, or independently re-derives the proper-time/operational reconstruction of (even linearized) GR — not a later de Haro paper, not a press summary, not the Springer book.
- Or a substantive critique/engagement from an independent philosopher or physicist of GR foundations (the Lehmkuhl/Curiel end of the field) that treats the program as worth arguing with.
- Failing either: the honest outcome is that the branch stays at
seedlingwithindependent_roots: 1, and no further claim-note is spun off this source until corroboration lands.
Notes
- No network access in the promotion organ by design; this is a queue item for a future web/verification session, not something to fetch now.
- Distinct person from Sebastian de Haro (quantum gravity / background-independence) — namesake collision, do not conflate in retrieval.
