No tested 2–16 hour dimming profile reaches score six in seven corrected TESS sectors of HD 110058

We test public 120 second TESS SPOC light curves of HD 110058 for isolated dimmings. The sample has seven sectors from 2019 to 2026 and 176.06 days of disjoint retained spans, including gaps. A fixed search fits symmetric trapezoids and asymmetric triangles with full durations of 2, 4, 8, and 16 hours. It fits a local quadratic baseline and uses an empirical depth scale. None of 150341 primary PDCSAP fits reaches score six. The largest positive score is 5.159. The score has no calibrated false-alarm probability. SAP checks have five groups of threshold crossings; their causes remain unclassified. We add separate artificial events at 84000 sampled times and four depths, for 336000 recovery tests across three shapes. At 1000 ppm, effective exposure ranges from 1.25 to 108.85 days for trapezoids and from 0.02 to 32.74 days for asymmetric triangles. The tested 250–500 ppm profiles have at most 2.09 effective days by point estimate. Recovery depends strongly on depth, duration, and shape. These measurements apply after extraction and correction. They do not establish that planets or comets are absent. We preserve the original data, archive query, hashes, source code, full search grids, injection trials, figures, and reproduction instructions.
