A fixed-cadence phase test finds no mean excess in 144 selected Kepler timing sequences
We test whether timing waves at a fixed Kepler cadence alias keep their phase across two mission halves. We use a verified subset of the Holczer catalog. Common coverage at the predicted frequency and 40 nearby control frequencies leaves 144 hosts and 50,513 records. Mean phase agreement is 0.00522 at the predicted frequency and 0.00208 at controls. The difference is 0.00315, with a host bootstrap 95 percent interval from -0.12307 to 0.13043. We find no mean excess in this restricted test. Two strong individual leads are a known dust-transit system and a catalog false positive. Neither is a new planet candidate. A fixed cadence, selection by coverage, possible correlated timing noise and lack of independent photometry limit the result. The package preserves input values, code, provenance, controls, checks and figures.

We reuse its verified timing subset and source provenance. We add host-specific cadence-alias fits and local-frequency controls.
