What this record contains (PDF-only release)
This Zenodo record contains the v2.7.1 manuscript PDFs for:

1. Main manuscript: Radiatively stable vacuum energy from a gauged constant vacuum mode: Local Einstein equations with a flux-fixed Λ_eff (v2.7.1)

2. Supplementary Material S1: Audit backbone for the v2.7.1 manuscript (operator inventory, threat model, toy thresholds, and existence-proof extracts)

No LaTeX sources or code are included in this deposit (by design).

One-paragraph summary (what the paper is claiming)
The manuscript formulates a low-energy EFT in which the strictly spacetime-constant vacuum mode is isolated into a compact/topological flux sector (three-/four-forms + membranes), while local excitations gravitate normally. On the minimal “GR-local” branch, the local Einstein equations are exactly GR with a constant term Λ_eff that is an integration constant fixed by global flux/integration data. The central claim is operator-level and conditional: strictly constant additive shifts of the vacuum functional renormalize only the flux-fixed constant mode and do not reappear as a freely running local cosmological-constant coupling in the local equations, provided a stated operator inventory holds.

What is (and is not) expected observationally
On the GR-local branch, once Λ_eff is fixed by observation, the late-time background and linear perturbations remain at the GR + w = −1 fixed point, so standard late-time “EFT of dark energy” parameter constraints are not expected to directly “see” the constant-mode mechanism itself; the tests are instead operator-level (red-line operators + the UV suppression criterion + the S1 audit).

What S1 is for (how a referee can check the claim)
Supplementary Material S1 is written as a referee-oriented audit backbone: it includes an IR operator inventory/checklist, a nonperturbative threat model (wormholes/instantons), UV-embedding templates, explicit toy “protected-λ” threshold tables/overlays, and compact “in-package” existence-proof extracts referenced by the main text.
