How do you offer a delivery slot at checkout that the network can honour?

Answer
Short answer
A slot shown at checkout has to be a reservation against remaining route capacity measured in minutes rather than a count of orders, and the flow behind it needs an offline-tolerant driver app, proof of delivery sized to the risk, and a designed path for the attempt that fails.

Likely follow-ups
- Two customers in the same postcode pick the same narrow slot. Should the second one have been offered it?
- A driver marks a parcel delivered but the photo shows the wrong door. What flow catches that?
- How would you price or nudge slots to shape demand towards routes you can serve cheaply?
- What changes if the customer can redirect a parcel while it is already on the van?
