Two Kepler apertures show secondary dips but no clear alternate-event depth difference in Q10 and Q16

We tested alternate-event depths for the nearby pair KOI-7865.01 and KOI-7866.01. Public Kepler Q16 and Q10 light curves give even-minus-odd PDCSAP depths of -0.6 +/- 46.4 and 15.0 +/- 35.6 ppm with a central half-width of 0.03 days. Neither supports an unequal-eclipse binary at twice the catalog period near 0.518 days. Both apertures show a secondary dip near half the catalog period, also in SAP flux. This supports further binary tests at the catalog period. Both archive entries already have a stellar-eclipse flag. We establish no new planet, binary, or host assignment. The tests use different times and channels on one telescope. Equal eclipses, a hot planet, contamination, and instrument errors are not fully excluded. The package preserves raw files, hashes, event tables, two timing models, sensitivity tests, figures and offline code.
