We publish the scheduler's assumptions because a plan you cannot argue with is a plan you cannot trust. Every board Waylight cuts carries the constraints it was cut under, in plain language, at the top of the sheet.

When the plan changes, it says why. A reshuffle that cannot name its cause is withheld and flagged for a human instead of published, which happens about once a fortnight and is the feature working, not failing.

None of this makes the scheduler smarter. It makes it accountable, which in a yard is worth considerably more — a crew will work around a constraint they understand and will quietly ignore an instruction they do not.

That is the whole design brief, and it is why the product looks like an instrument rather than an assistant. Instruments show their reading and let you decide.
