3502 — Mirror Completion Preserves Source Gates but Reverses Sign Readout
Claim
The genuinely chiral charge packet
and its complete mirror both cancel their linear and cubic anomalies. Their quadratic RG weight is , and all even threshold moments agree.
For a mirror-odd portal contrast, an equivariant beta function has paired fixed points with identical critical exponents. Mirror-equivariant finite matching transports both signs, and inclusive widths remain sign blind. A parity-labelled instrument can separate the signs with positive response Gram value , but that readout has no authority to remove the mirror constructor from the source domain.
Classification
Anomaly consistency, RG attraction, threshold survival, and inclusive readout select at most a mirror orbit. A parity instrument identifies the realized branch but does not select it.
The missing principle must be a non-mirror-completable boundary or incidence object admitted independently of the desired flavor record. It must also fix the continuous portal normalization and threshold clock.
