Two TESS sectors recover tested circular transit models of 2 Earth radius planets near 2.5566 days at HD 32564

HD 32564 has a reported radial velocity signal near 2.5566 days. Its physical cause is not established. We search public TESS light curves over 2.5563 to 2.5570 days. No box signal reaches the stated score threshold. The largest score in the primary aperture flux from Sectors 5 and 32 is 4.86; the threshold is 7.41. We add physical transit models before our spline fit and repeat the full search. The test assumes a circular orbit and constant transit times. We adopt stellar mass 0.98 solar mass and radius 0.939505 solar radius. It uses three periods, 64 phases, impact parameters 0, 0.4, and 0.8, and five planet radii. All 576 additions with planet radius 2 Earth radii pass the score and event match rules. Their lowest score is 13.63. A further 768 of 768 additions pass under eight specified changes to the model or flux treatment. These are results for finite model grids in the retained data. They do not establish a planet, exclude every transit, or give a planet probability. The package contains input FITS files, source records, all trial results, code, and figures.
