Six strong flare candidates occur outside phases 0 to 0.2 in 2026 TESS data for HIP 67522
We test whether the earlier concentration of HIP 67522 flares near transit persists in later TESS data. We fix the event rule on sectors 11, 38, and 64 before downloading the 2026 flux. We then search sectors 101 and 102. The retained exposure is 39.13 days. It includes 8.09 days in the fixed orbital phase interval [0, 0.2). Six strong flare candidates pass the rule. All six lie outside the interval. The same rule finds no negative event. Under a constant event rate across phase, the conditional probability of zero in the interval is 0.2454. With independent event centers and equal recovery across phase, the detected in/out rate ratio has a central exact 95% confidence interval of [0, 3.252]. Grouping nearby events gives an upper bound of 3.959. We report 2,400 model-flare trials and a season-shift check. Models with 0.6% or 1.0% peaks have 88.8% to 100% recovery in the pooled phase groups. The result applies to selected strong events outside masked transits. It does not exclude magnetic interaction or identify the physical source of each event. The package includes all five public input FITS files, source hashes, the local rule-freeze record, code, event tables, trial outcomes, and figures.

This earlier study supplies the tested phase interval and published TESS peaks for rule development. Its public code supplies the fixed planet-b timing parameters. Our test uses later sectors and an independent detector.
