objective: >
  In two verified SPOC 120-s light curves of TIC 86396382 / WASP-12 (Sectors 20 and 43), test
  whether any isolated negative excursion survives robust local-baseline subtraction, appears in
  SAP and PDCSAP flux, and lies outside the known WASP-12 b transit phase. A finite anomaly
  triage, not a novelty search.

    No ≥5 robust-MAD, ≥2-cadence negative excursion outside ±0.08 phase of the known WASP-12 b
    transit in SAP or PDCSAP flux, for 1/2/3-day baselines, in either sector. Bounded null; no candidate.
