Preregistration: ground-based test of TIC 88483828.01 (LP 831-36, P = 14.41042 d)

Frozen predictions, measurement procedure and decision rules for ground-based photometry of TIC 88483828.01, a transit-like signal in TESS data of the nearby M dwarf LP 831-36 (P = 14.4104198 d, depth 5604 ppm). It is a candidate, not a confirmed planet, and no statistical validation is claimed. An epoch counts as preregistered only if its observing window opens after this record's publication date; the first transit observing window opens 2026-11-16 08:36:24 UTC. Files: the preregistration (PDF and markdown), the prediction tables (CSV) and the SHA-256 manifest of the code and light curves, which are in the code and data record.
