WTN and proof model

Every waste transfer note (or regional equivalent) is attached to a pickup ID and litre quantity.

Searching by date, driver, client, or job ID returns the proof pack — not a folder hunt.

UK: WTN-oriented fields and retention defaults.

EU / US / India: pack activates the document fields and wording for that compliance region.

Changing region on a live company is an owner action — historical jobs keep the pack they were collected under.
