gantt: dependency cycle detected ({path}); schedule refused.

What happened

The dependency graph contains a cycle, so there is no order in which the tasks can be scheduled and the critical-path pass refuses rather than producing an arbitrary answer. The schedule result is { ok: false } with the cycle listed, and no dates are computed. The key carries the cycle, so two different cycles are two lines.

The fix

Break the cycle named in the message - the arrow chain is printed in order - by removing or reversing one of the dependencies.
