"""PlayerCaseView - the case as the player may see it.

Everything that would spoil the mystery (the solution, ``is_culprit`` flags, anchored
lies, true whereabouts, private secrets) is stripped here. The full CaseFile is never
handed to the UI process state; only this projection and discovered clues are.
