For 44 fixed periods of TOI-941.02, 29 ideal visits of 10 hours separate all 34 timing groups on the tested 2026–2027 grid

Two reported TESS events leave 44 possible fixed periods for TOI-941.02. We use the verified source fit and ask which periods complete transit records can distinguish between BTJD 4338 and 4496, about 2026 October 24 to 2027 March 31. Exact rational event times give 34 distinct groups. Eight models predict no event, and three other pairs share all event times in the season. We bound each endpoint by three quoted error widths and allow the duration to increase by three quoted widths. Each record must contain the full allowed transit and 0.5 hours of baseline on each side. Of 53 records centred on predicted events, 29 records of 10 hours separate all 915 distinguishable model pairs. A certificate with 29 disjoint comparison requirements proves that this count is the minimum on the tested grid. An equally small set that favours earlier records finishes by 2027 March 3. An extra centre displacement of plus or minus 0.5 hours preserves all separations with 10-hour records. A displacement of plus or minus 1 hour requires longer records under this rule; 12-hour records restore all separations. Independent Decimal arithmetic checks all 20,196 response entries across nine cases. The result assumes the supplied 44 periods, one body on a constant period, stable transits, successful recovery, and complete records. We do not apply telescope visibility or weather constraints. We preserve the signed source, code, provenance, tables, figures, and reproduction steps. This work gives an observation design; it reports no new transit or confirmed planet.

    We use its two event centres, quoted fit widths, transit duration, 44 allowed cycle counts, and nominal ephemeris of TOI-941 b. We preserve its complete signed package. We condition on its period exclusions and do not repeat them.
