# NS-DRC Cycle III — Standard PDE Recompilation v1.0

## 1. Scope

Cycle III studies how high-frequency dangerous state can survive, be replenished, hide inside source multiplicity/cancellation, remain near the dissipation boundary, or become globally diluted.

Its main achievement is a Type-I reservoir-mechanism classification closure.

It does not prove universal singularity exclusion.

## 2. Exponential preload becomes source history

A high-frequency state required at a later time cannot survive many viscous ages from a fixed smooth past without either:

- exponentially large actual high-tail preload;
- or Duhamel replenishment.

Repeating Duhamel into the prehistory shows exponentially large high-tail preload itself requires earlier high-frequency forcing.

Thus source-free exponential preload is removed.

## 3. High-frequency forcing has parent state

Quadratic-vorticity high-frequency replenishment has a signed exact parent ledger and a deterministic bilinear parent-state envelope.

Under bounded source/state amplification and finite parent complexity one obtains actual high-parent state carriers.

## 4. Deterministic frequency weight

For scale-local high-parent interactions, the natural Hdot1-vorticity state weight includes a deterministic:

$$
2^{5h/2}
$$

factor.

After this weight is removed, local source amplification is backed by a finite parent-cluster state stock.

## 5. Deep dissipation interactions

Relative to the Cheskidov--Shvydkoy dissipation wavenumber, high-frequency interactions lying entirely in the deep dissipative range are viscosity-small.

Non-absorbable source is tied to:

- low-mode driver activity;
- or a finite transition neighborhood of the dissipation boundary.

## 6. Cancellation does not block net ancestry

If an exact net renewal vector is grouped over finitely many high-parent shell labels and has positive norming-dual total:

$$
R>0,
$$

then at least one parent shell has positive net contribution:

$$
\ge R/K.
$$

No uniform bound on the positive/negative gross cancellation ratio is needed.

## 7. Parent multiplicity becomes dissipation span

The number of transition high-parent shell labels is bounded by:

$$
C_L
\left(
1+
[Q_I^+-J]_+
\right).
$$

Thus unbounded many-parent transition multiplicity is a dissipation-boundary-span mechanism.

## 8. Dissipation-range renewal has low-mode driver ancestry

After viscosity-small source is removed, active quadratic-vorticity forcing satisfies a forcing-level estimate of the form:

$$
\|\mathcal F_J^{act}\|_{\dot H^1}
\lesssim
\Omega_Q
X_J.
$$

A strong renewal node therefore pays a low-mode driver-action packet or is re-rooted to a larger earlier high-frequency state.

Repeated re-rooting cannot continue into a fixed smooth early-time region at arbitrarily high fixed frequency.

## 9. Type-I absolute local core

Under the Barker--Prange Type-I hypotheses, a singular point has absolute scale-invariant local enstrophy concentration:

$$
R_I
\int_{B_{R_I}}
|\omega|^2
\gtrsim_M
1.
$$

Low-frequency exclusion gives an absolute UV core:

$$
R_I
\|
P_{>J_I}\omega
\|_{L^2(B_{R_I})}^2
\gtrsim_M
1,
\qquad
2^{J_I}R_I\asymp1.
$$

## 10. Same-center backward core reuse

Barker--Prange backward propagation yields same-center concentration at well-separated earlier times.

Choosing geometric times gives an arbitrarily deep nested Type-I state chain.

## 11. Global dilution is not loss of the local state

A vanishing global core share means larger ambient global enstrophy.

It does not destroy the absolute local core or UV core stock.

Thus global dilution is a normalization/accounting issue for local Type-I ancestry.

## 12. Local core injects into global high-pass state

The absolute local UV lower bound implies:

$$
\|P_{>J}S\|_{\dot H^1}
\gtrsim
M R^{-3/2}.
$$

Hence the local Type-I state can enter the global high-pass Duhamel state space.

## 13. What is not proved

The following are not proved:

- localization of the global Duhamel source ancestor to the same singular-core branch;
- recursive compatibility of selected source parents as ancestry nodes;
- arbitrarily deep compatible finite source paths;
- non-Type-I ancestry entry;
- Finite Obstruction.

## 14. Type-I reservoir status

Relative to the DRC census:

$$
\boxed{
\text{Type-I unexplained reservoir residual core}
=
\varnothing.
}
$$

## 15. Chain-Necessity status

$$
\boxed{
\text{Type-I state ancestry skeleton}
:
\mathrm{PROVED}
}
$$

$$
\boxed{
\text{Type-I source-traceable infinite ancestry}
:
\mathrm{OPEN}
}
$$

$$
\boxed{
\text{Full Chain Necessity}
:
\mathrm{OPEN}
}
$$

## 16. Finite-Obstruction status

The current coercive actions are necessary-dangerous quantities, not a complete impossibility cover.

$$
\boxed{
\text{Finite Obstruction}
:
\mathrm{OPEN}
}
$$

$$
\boxed{
\text{3D Navier--Stokes regularity}
:
\mathrm{OPEN}
}
$$
