Unknown time near Lichun: disclose the remaining boundary risk

This case adds a second problem to the previous one. The birth time is unknown, and the date is the Lichun date itself: 4 February 2026, with the boundary falling at 04:02 that morning. Two uncertainties compound: the hour is missing, and the year boundary falls inside the same day, so even the pillars derived from the date carry risk.

The honest consequence is broader than a missing hour pillar. With an unknown time and a date on a solar-term boundary, the year and month pillars could in principle move as well, because on this date the Lichun boundary falls at 04:02, so a birth in the small hours and one later the same morning land on opposite sides of it. The public output shows three pillars and says plainly that time-sensitive conclusions require record review.

This is the least comfortable case in the suite and the one worth reading most carefully. It is a case where the correct answer to the question of what your chart is happens to be partly that it depends on information you do not have. Presenting it that way is the point.

Readers sometimes read a three-pillar result as a weaker version of a four-pillar one, as though the same chart were simply missing a column. Near a boundary that reading understates the problem. What is missing is not one pillar but the confidence that the remaining three are stable, and those are different kinds of absence.
