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 [[entity-dennis-lehmkuhl|Lehmkuhl]]/[[entity-erik-curiel|Curiel]] end of the field) that treats the program as worth arguing with.
- Failing either: the honest outcome is that the branch stays at `seedling` with `independent_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 [[entity-sebastian-de-haro|Sebastian de Haro]] (quantum gravity / background-independence) — namesake collision, do not conflate in retrieval.
