A closure is never local. Nexus computes what moves, what doesn't, and what the diversionary routes can genuinely absorb.
Every diverted service competes for the same scarce paths.
Performance regimes and contracts turn delay into money on a schedule.
The timetable locks before the full picture arrives - unless the picture is computed.
A landslip closes the coastal line for ten days. What moves, and what doesn't?
RECEIPT · SIGNED, REBIRTH NEXUS · every figure above names the engine that computed it - open any step.
Illustrative scenario - not live client data.
Tell us the decision you face, and a deterministic, tested, documented engine appears inside the same governed doorway - in days, not quarters.
One use case, your data, 30 days - and a receipt on everything. If seeing the full picture doesn't change the decision, you walk away.
