# UQF-9 — UV Completion / Asymptotic Safety

## What this gate must establish

A predictive theory must remain sensible at arbitrarily high energy: either it has a genuine high-energy completion (a non-Gaussian / asymptotically-safe fixed point that tames the short-distance behaviour), or the very notion of "all the way to infinite energy" must be replaced by something physically defensible. This gate asks whether the Fable geometry survives the ultraviolet — and, honestly, whether the question is even posed correctly.

## The geometry's role (load-bearing, not validation)

The frozen 13D shape fixes the operator whose short-distance behaviour decides the UV question: the de-Donder graviton Laplacian at d=13, whose Seeley-DeWitt heat-kernel coefficient **a₆** (the named missing object of the companion Gap-01) carries the relevant data. The geometry also supplies the candidate cost-floor lens: a posited nonzero minimum operational "grain" below which no distinguishable transition occurs. That granularity premise is what reframes the UV question — but supplying the operator and the lens is *setup*, not a proof that a fixed point exists or that the completion is consistent.

## Current honest status

Two readings, both true, neither a closure:

- **Standalone gate (the conservative read): AUDIT (OPEN).** As one of the eight UQF audit rows, UQF-9 stays at AUDIT. A candidate non-Gaussian fixed point exists only *at a declared truncation*; a full UV completion is a global open problem shared with all of quantum gravity. The required input — a 6th heat-kernel coefficient (a₆) — is **necessary-not-sufficient**, and is itself **not computed** (Gap-01 is Precisely-OPEN, "walled at field grade"). No fixed point has been exhibited.

- **The granularity / cost-floor leg: AXIOM-CLOSED — and dissolved, not solved.** Elevating the cost floor (`AXIOM-COSTFLOOR`) to a root principle *dissolves an entire class of continuum-limit artifacts* — the unbounded a₈/a₁₀ Seeley-DeWitt counterterm tower and the associated a→0 UV-divergence idealization — at a cost of **one** named, value-free axiom. This is the "one deep root that kills a whole class" win. But the discipline is strict: **DISSOLVED is not SOLVED.** Dropping a false premise (that physics requires a literal continuum limit) makes that class of divergences disappear; it does **not** exhibit a fixed point, does **not** compute the finite a₆ coefficient (which exists term-by-term at any spacing *and* in the continuum, so the floor does **not** dissolve it), and leaves a genuine finite obligation open.

Named axioms / blockers: `AXIOM-COSTFLOOR` (the dissolution root; a confession, not a theorem — any deeper "must be physically realizable" principle is an equal-strength relocation). Blocker: `GAP01-A6` — the d=13 graviton+ghost a₆ trace, a heavy-but-finite symbolic computation, uncomputed. Downstream: UQF-10 (compactification stability) and UQF-14 (graviton-sector unitarity above the cutoff) are **blocked by** UQF-9. **No status was ever upgraded.** The headline ceiling holds: serious candidate / partial unification — **NOT validated**. Note that the cost-floor leaves the cosmological-constant radiative-stability wall and the finite Λ value entirely **untouched**.

## What would close it

There is no single clean closure; the honest path is two-pronged and partial:

1. **The finite obligation (a route, not a result):** compute the d=13 de-Donder a₆ trace over the cubic-curvature invariant basis and verify the positive-definiteness criterion for physical-Hilbert-space closure. This is "perturbative but heavy" — a definite computation, refutable (a positivity violation would refute Gap-01 at decision grade), but **not yet run**, and a single consistent coefficient does **not** by itself constitute a UV completion.

2. **The wall behind it (likely no-go by ordinary means):** exhibiting a genuine non-Gaussian fixed point beyond a truncation is a global open problem of quantum gravity. The cost-floor leg does not cross this wall — it removes the *need* to take the continuum limit by declaring it out of scope, which is a defensible reframe, not a theorem about a fixed point. Closing the gate in the strong sense requires either an exhibited, truncation-independent fixed point or an independent proof that the granularity premise is forced by reality rather than posited.
