At 47 cycles, the 2024 WASP-134 dip is within 2.4 propagated standard errors of the printed planet c clock for every allowed covariance

The known isolated TESS dip TOI-5812.02 may belong to the radial velocity planet WASP-134 c. The printed outer-planet clock puts conjunction 11.41385 days before the dip at cycle 47. The period–epoch covariance is absent. We treat the printed errors, 0.14 and 1.8 days, as marginal standard deviations. For every valid covariance, the propagated timing error is 4.78 to 8.38 days. The dip is 1.362 to 2.388 standard errors late under a constant-period clock and an independent dip error. This bound needs no Gaussian distribution. Of integer cycles 0 through 100, only 47 can pass a three-standard-error screen. A separate trapezoid time check uses the public Sector 82 SPOC flux. Six window and baseline choices agree within 24 seconds of the prior SCI time. We also condition a family of Gaussian clocks on the dip. This assumes that the dip is planet c. Across all correlations, conditional period means span 70.200685 to 70.344297 days. The union of pointwise 95% center-time intervals for cycle 12 after the dip is BJD TDB 2461377.976 to 2461380.490. This is about 3 to 5 December 2026. These are conditional planning limits, not a measured new orbit or a probability of planet identity. The package contains original code, public input flux, source records, numerical checks, figures, and dated tables.
