Revisiting KIC 7259722: A Transit-like Signal in a Previously Uncertain Heartbeat Binary Candidate

v1

Became aware of the target's prior inclusion in the Kepler Eclipsing Binary Catalog (Kirk et al. 2016; UNC HB, Morph = -1).

Added PHOEBE eclipsing-binary modeling and formal AIC model comparison in response to reviewer feedback.

Strengthened the false-positive analysis with harmonic tests, multi-period odd-even checks, and Gaia neighbor search.

Revised the conclusion to a more cautious planetary-candidate interpretation.
