**Physical promotion:** `0`

## 1. Question

Can current UD derive an absolute physical substrate frequency \(\nu_0\) from its existing internal frequencies, recurrences, and action geometry without importing a further dimensionful non-\(G\) anchor?

**Answer:** No, under the current source laws.

UD can derive exact **relative / dimensionless clock structure** and conditional physical-frequency families, but not the absolute SI clock scale.

## 2. Current unit identities

Current canon contains:

\[
c=\frac{a_0}{\tau_0},
\]

\[
\mathcal A_0
=
B_0\frac{a_0^2}{\tau_0},
\]

and the current convention-invariant action ratio

\[
\eta_{\mathcal A}
:=
\frac{\mathcal A_0}{\hbar},
\qquad
\mathcal A_0=\eta_{\mathcal A}\hbar.
\]

Here \(B_0\) is mass-like.

Substituting \(a_0=c\tau_0\),

\[
\mathcal A_0
=
B_0c^2\tau_0.
\]

Hence

\[
\boxed{
B_0\tau_0
=
\frac{\eta_{\mathcal A}\hbar}{c^2}
}.
\]

Even if a numerical \(\eta_{\mathcal A}\) were known, this fixes only the **product**
\(B_0\tau_0\), not \(B_0\) and \(\tau_0\) separately.

Current canon also leaves the numerical value of \(\eta_{\mathcal A}\) open.

---

## 3. Scale-gauge theorem

### Theorem

Let a current UD solution be expressed in native units
\((a_0,\tau_0,B_0)\) and dimensionless internal variables.

For any real

\[
\lambda>0,
\]

define

\[
\tau_0'
=
\lambda\tau_0,
\]

\[
a_0'
=
\lambda a_0,
\]

\[
B_0'
=
\frac{B_0}{\lambda}.
\]

Then:

\[
\frac{a_0'}{\tau_0'}
=
\frac{\lambda a_0}{\lambda\tau_0}
=
c,
\]

and

\[
B_0'
\frac{(a_0')^2}{\tau_0'}
=
\frac{B_0}{\lambda}
\frac{\lambda^2a_0^2}{\lambda\tau_0}
=
B_0\frac{a_0^2}{\tau_0}
=
\mathcal A_0.
\]

Therefore

\[
\eta_{\mathcal A}'
=
\frac{\mathcal A_0'}{\hbar}
=
\eta_{\mathcal A}.
\]

All current dimensionless internal equations, spectra, combinatorial counts, and native ratios are unchanged by this transformation.

Thus the current theory has a continuous one-parameter **physical scale gauge**

\[
\boxed{
\mathscr S_\lambda:
(a_0,\tau_0,B_0)
\mapsto
(\lambda a_0,\lambda\tau_0,B_0/\lambda)
}.
\]

### Consequence

Any internal dimensionless angular frequency \(\widehat\omega\) maps conditionally to

\[
\omega_{\rm phys}
=
\frac{\widehat\omega}{\tau_0}.
\]

Under \(\mathscr S_\lambda\),

\[
\omega_{\rm phys}'
=
\frac{\widehat\omega}{\lambda\tau_0}
=
\frac{\omega_{\rm phys}}{\lambda}.
\]

Likewise, if \(\widehat\omega\) is angular frequency,

\[
\nu_{\rm phys}
=
\frac{\widehat\omega}{2\pi\tau_0}
\]

and therefore

\[
\boxed{
\nu_{\rm phys}'
=
\frac{\nu_{\rm phys}}{\lambda}.
}
\]

Since all native current observables are invariant while the physical clock changes continuously with \(\lambda\), no current internal dimensionless object can select a unique physical \(\nu_0\).

\[
\boxed{
\text{Absolute physical clock scale is nonidentifiable under current UD laws.}
}
\]

---

## 4. Gravity consequence of the same scale gauge

The current native-to-SI gravity map is

\[
G_{\rm SI}
=
\gamma_G
\frac{a_0^3}{B_0\tau_0^2},
\]

with

\[
\gamma_G=\frac{3}{4\pi}
\]

inside the tested native gravity protocols.

Under \(\mathscr S_\lambda\),

\[
G_{\rm SI}'
=
\gamma_G
\frac{\lambda^3a_0^3}
{(B_0/\lambda)(\lambda^2\tau_0^2)}
=
\lambda^2G_{\rm SI}.
\]

Therefore the same unclosed physical-clock scale is exactly the remaining scale freedom in the SI gravity bridge:

\[
\boxed{
G_{\rm SI}\mapsto\lambda^2G_{\rm SI}.
}
\]

This is why obtaining a native dimensionless gravitational coupling does not by itself determine Newton's SI constant.

---

## 5. Candidate internal clocks do not close the gauge

### 5.1 Retained-Hamiltonian mode

Current internal mathematics contains

\[
\widehat\omega_\star
=
\sqrt{\frac{33}{8}}
=
\frac{\sqrt{66}}{4},
\]

with

\[
66=2\cdot3\cdot11.
\]

Its conditional cycle-frequency family is

\[
\boxed{
\nu_\star(\tau_0)
=
\frac{\sqrt{66}}
{8\pi\tau_0}
}.
\]

This is exact **conditional on the chosen physical tick \(\tau_0\)**.

It does not determine \(\tau_0\).

### 5.2 K4 chain mode

The internal chain object

\[
\widehat\omega_{K4}=2
\]

would conditionally map to

\[
\nu_{K4}(\tau_0)
=
\frac{1}{\pi\tau_0}
\]

if interpreted as an angular frequency on the same physical evolution parameter.

Current canon explicitly blocks that physical-frequency identification until a unit/evolution-parameter bridge exists.

### 5.3 Event-time coordinate

The exact internal object

\[
\tau_E=\frac34
\]

is a geometric/event coordinate, not physical seconds.

It is therefore not an independent dimensional anchor.

### 5.4 Normalized stochastic event rate

The exact conditional values

\[
q_E=\frac1{30},
\qquad
\gamma_E=\frac43
\]

are normalized jump-count/event-parameter objects. Their own governance requires a physical clock bridge.

They cannot be used to prove that same bridge without circularity.

---

## 6. Common-recurrence route is exactly blocked

The current support spectra include

\[
{\rm Spec}_A
\supset
\{\pm i\sqrt3,\pm i\sqrt5\},
\]

and

\[
{\rm Spec}_{B,C}
\supset
\{\pm i\sqrt2,\pm i\sqrt5\}.
\]

Suppose a finite nonzero period \(T\) existed for the \(A\) support modes. Then there would be nonzero integers \(m,n\) such that

\[
\sqrt3\,T=2\pi m,
\]

\[
\sqrt5\,T=2\pi n.
\]

Dividing,

\[
\sqrt{\frac35}
=
\frac{m}{n}.
\]

But \(\sqrt{3/5}\) is irrational, contradiction.

Likewise a finite common period for the \(B,C\) modes would imply

\[
\sqrt{\frac25}\in\mathbb Q,
\]

also false.

Therefore:

\[
\boxed{
T_{\rm common}\neq{\rm finite\ nonzero}
}
\]

for the current global support recurrence.

This reproduces and strengthens the existing locked no-go: the micro-support spectrum cannot secretly provide a unique periodic substrate clock.

---

## 7. Ordinal evolution is not a physical clock

A discrete update count

\[
n=0,1,2,\ldots
\]

can define an ordinal clock:

\[
N_\Omega=n.
\]

But the physical time assignment remains

\[
t_n=n\tau_0.
\]

Under the scale gauge,

\[
t_n'
=
n\lambda\tau_0
=
\lambda t_n.
\]

Thus update order is invariant while update **duration** remains free.

Consequently:

\[
\boxed{
\text{ordinal causality does not determine SI duration.}
}
\]

---

## 8. Strongest lawful clock bridge

Current UD therefore supports the exact family

\[
\boxed{
\nu_0
=
\frac{\widehat\omega_0}
{2\pi\tau_0}
}
\]

for any properly typed internal angular-frequency carrier \(\widehat\omega_0\), but \(\tau_0\) remains gauge-free.

If the retained-Hamiltonian mode is selected by an independently justified clock-carrier theorem,

\[
\boxed{
\nu_0
=
\frac{\sqrt{66}}
{8\pi\tau_0}
}
\]

is the corresponding conditional bridge.

This is not yet a physical prediction.

---

## 9. What can break the scale gauge?

A lawful closure requires **one source that is not invariant under \(\mathscr S_\lambda\)**.

At least one of the following must be supplied independently:

1. a physical frequency / time anchor,
2. a physical mass / energy anchor tied to an independently identified packet,
3. a physical length anchor,
4. another dimensionful non-\(G\) observable with a source-complete UD carrier.

Forbidden:

- Newton's \(G\),
- Planck mass,
- Planck length,
- Planck time,
- a redshift result used to tune the clock after target exposure,
- assigning seconds to an internal frequency merely because its number is exact.

---

## 10. Source-addendum gate

The current route is impossible **under existing laws**, but UD governance permits a new source addendum.

A future clock addendum is admissible only if it supplies a map

\[
\mathfrak C:
(\text{native carrier},\text{independent dimensionful observable})
\longrightarrow
\tau_0
\]

with:

- explicit carrier type,
- transformation law under \(\mathscr S_\lambda\),
- target-blind normalization,
- no \(G\) or Planck-derived input,
- null/reduction limit,
- falsification criterion,
- independent evidence that the chosen internal mode is the physical clock carrier.

A purely dimensionless source addendum cannot close the scale gauge.

---

## 11. Verdict

### EXACT
- scale-gauge symmetry \(\mathscr S_\lambda\);
- conditional frequency family;
- no finite support-recurrence period;
- ordinal-clock / physical-duration distinction.

### NO-GO
\[
\boxed{
\text{Current UD internal lineage cannot derive an absolute SI substrate frequency \(\nu_0\).}
}
\]

### OPEN
- a source-complete physical clock carrier theorem;
- one independent dimensionful non-\(G\) anchor;
- numerical \(\eta_{\mathcal A}\).

### PHYSICAL PROMOTION
\[
\boxed{0}
\]

The correct result is a **proof of nonidentifiability**, not a failed numerical search.
