TESS 2-min data of 146 CVZ TOI hosts show no new vetted transit candidates from 1 to 150 d, and an eccentric secondary eclipse shows that TOI-1229.01 is an eclipsing binary

We searched TESS SPOC 2-min light curves of 146 TOI hosts in the continuous viewing zones (Tmag < 11, median 39 sectors over 1,979 days) for additional periodic transits from 1 to 150 days. We masked all known transits before detrending, ran a box least-squares search, and vetted all 177 peaks with SNR of 10 or more. The vetting errors come from random off-transit epochs of the same star, so they include correlated noise. No peak passed all tests, except signals at the period of a known TOI. The same pipeline on inverted flux gave 0 passes from 152 peaks. Injected transits passed vetting in 36 of 54 cases. Injection tests show limited sensitivity: 83% recovery at white-noise SNR 18 to 20, and 14% recovery for periods of 30 to 150 days. Thus the null result does not exclude typical small planets. A scan of all orbital phases at the periods of 145 TOIs found two secondary eclipses above the largest control value. TOI-1307.01 has a 609 ppm eclipse at phase 0.50; an ExoFOP note already reports this. TOI-1229.01 (P = 31.8 d, TFOP APC and SB1) has a 505 +/- 37 ppm eclipse at phase 0.7248. SPOC 2-min, TESS-SPOC FFI, and QLP FFI photometry show it at the same phase. A planet at this period can give at most about 16 ppm, so the companion is self-luminous. The timing and duration give e cos(omega) = 0.353 and e sin(omega) = -0.08 +/- 0.02. The depth ratio gives a companion brightness temperature near 3,040 K, which agrees with an M dwarf. The scan also recovered the known occultation of WASP-100 b (67 ppm) and found a tentative 108 ppm dip at phase 0.5 for TOI-1181 b. Limits: bright CVZ hosts only, first-order eclipse approximations, blackbody temperatures, and no new spectroscopy. The bundle includes code, per-file hashes, and all evidence tables.
