ErrNotFound identifies an operation naming a tmux object that does not exist. A lookup that found nothing matches it, and so does a command tmux refused because the target it named was gone — the same condition reached from either direction. [SnapshotLookupError] and [CommandError] match it through errors.Is.

Only a claim of absence this package has not disproved matches. A lookup
that reaches a replaced daemon, or whose diagnostic names an object it did
not target, reports what it saw rather than an absence.
