"""End-to-end numbering walkthrough for the 2026-05-12 parent-number
hierarchy. Quote -> confirm -> 2 invoices (partial billing) -> CoC ->
delivery -> receiving -> NCR (legacy fallback) -> Hold (parent-derived)
-> immutability check -> unlink block check -> direct invoice block.

Asserts every SO-linked doc shares the same parent number. Re-runnable;
rolls back at the end so no DB state is left behind.
