The demo BSN, password, and DigiD login sequence were copy-pasted verbatim
into all three specs; the diploma id #diploma-d1 was coupled to SeedData.cs's
ordering by comment only, with no compile-time check if the seed shape
changed. e2e/support/actors.ts names both: Actors.zorgverlener + loginAs()
for the login sequence, SeedRefs.diplomaZonderPolicyVragen for the seed
coupling (with the "why d1" reasoning attached to the name, not scattered
across specs). Zero assertions changed — pure extract-and-rename of test
setup. e2e test-isolation (the shared mutable backend) is a documented
follow-up, not fixed here — see ADR-0006.
