About this puzzle’s verification

Unique means exactly one of the 36 possible complete arrangements satisfies every clue. A hint is a fact true in every compatible arrangement, with a small set of supporting clues. This is separate from a human-style solving path.

MAKE YOUR FIRST CONNECTION

There’s a method
to the mystery.

You don’t need to guess. Start with one certain thing, then see what it rules out.

01 How a logic grid works

Each label is used exactly once. If Mira has the Moon bowl, mark that pair with ○. Mira cannot have either other object, and nobody else can have the Moon bowl: those four cells get ×. Each row and column eventually has one ○.

02 Earlier, adjacent, or immediately left?

“Earlier” allows any earlier time. “Consecutive” means neighboring slots in either order. “Immediately to the left” fixes both the direction and a one-position gap. Lantern Lane uses left-to-right houses in this same collection; it is a position (or zebra) logic grid.

03 Follow a deduction, step by step

Suppose Oren is at 10 am, and the Leaf pin is earlier than Oren. The only earlier slot is 9 am, so pair the Leaf pin with 9 am. If Tavi is not at 9 am, and Oren is already at 10 am, Mira must be at 9 am. Now Mira has the Leaf pin. Every step follows a clue or the one-of-each rule.

04 What does “verified” actually mean?

Our bounded solver checks every arrangement: zero means contradictory, one means unique, more than one means underconstrained. If the time budget runs out, the answer is unknown. “Exactly one of A or B” is exclusive OR; “at least one” allows both. Uniqueness alone is not a difficulty rating or a promise of a human-style route.
