1699 — Matching Z2 Parities Do Not Identify the Cubic, Conditioning, and Time-Root Covers

Typing audit

Entry 1698 exhibits a square-root deck action on the resolved conditioning normal. Compare it with the cubic-flow reversal and the previously identified cosmological time-root line.

Two derived actions

The exact cubic orbit has

$$t\longmapsto-t.$$

Entries 1692--1693 give

$$\kappa_3(-t)=-\kappa_3(t), \qquad \kappa_4(-t)=\kappa_4(t).$$

The conditioning Rees cover instead has

$$u\longmapsto-u, \qquad \Xi=u\otimes u\longmapsto\Xi.$$

Thus both constructions display an odd resolved coordinate and an even second grade.

Missing comparison

The actions have different provenance:

• t -> -t reverses the cubic unitary orbit;
• u -> -u is the deck transformation of a covariance square root;
• the cosmological time-root line comes from compatible regional energy-root choices.

No source-derived morphism currently identifies these three local systems.

Narrow result

$$\boxed{ \text{the parity representations agree, but identifying the cubic, conditioning, and cosmological time-root covers is currently untyped.} }$$

The agreement is evidence for a reusable resolved-normal calculus, not for one universal Z_2 coefficient. This preserves the distinction demanded by the cosmology evidence partition.

Next falsifier

Search the frozen source for an actual specialization or comparison map from the energy-root normal line to the Gaussian conditioning normal bundle. If no such map is present, keep the covers independent and test only functorial compatibility of their even Rees grades on shared Cut strata.
