One true answer is only the beginning
A solver can tell us that a puzzle has exactly one solution. It cannot tell us that a new player will enjoy finding it.
First, establish that the case holds together
In Murdok, spatial statements become constraints: a person belongs in a room, stands next to another person, or occupies a position relative to an object. Our production checks enumerate possible arrangements to verify a unique solution. If the statements allow two completed scenes, the case needs more work before release.
Then ask whether the next step is understandable
Uniqueness is a property of the whole case. A player works one step at a time. Deduction checks help us inspect whether the available evidence supports progress, but the wording, the board, and the order in which someone notices things still matter. A correct constraint can be an awkward sentence.
The picture and the rules have different jobs
The paintings set the atmosphere. The SVG geometry and executable statements define where people can stand and what the clues mean. Keeping those roles explicit makes it possible to check a case without asking a picture to carry an ambiguous rule.
Invite feedback on the reasoning, not just the ending
For the first public demonstrations, we show one clue and one placement. We want to know whether that move is understandable before asking someone to solve the whole case. The published difficulty labels are estimates from our checks, not measured completion times from a player study. That distinction matters when deciding what to improve next.
