Outcome: An NRC webhook consumer that, on zaak.gecreeerd, writes a row to a register_projection table with id, bsn, naam_placeholder, status. Idempotent. Rebuildable.

Acceptance:

  • BDD scenario: "Given a zaak is created in OpenZaak, when the NRC event is delivered, then the projection contains a row with status INGEDIEND."
  • Replaying the same event twice does not create duplicates.
  • A projection rebuild admin command repopulates from OpenZaak.

Touches: services/event-subscriber/, services/projection-api/, tests.

Out of scope: decision events, multiple projections, public-safe field filtering (will tighten in S-09).

Definition of Done

  • A linked Gitea issue exists (this one).
  • Failing test written and committed first.
  • Implementation makes the test pass.
  • Refactor commit follows if structure improved.
  • Conventional Commit messages referencing this issue (refs #NN).
  • All Gitea Actions CI jobs green: lint, unit, integration, mutation (ratchet), e2e, container build + push, compose-up smoke test.
  • docker compose up from a fresh clone reaches green health checks within 3 minutes.
  • Docs touched if behaviour, contracts, or operations changed.
  • ADR added in docs/architecture/ if a non-obvious decision was made.
  • Demo note appended to docs/demo-script.md if the slice is user-visible.
  • This issue closed by the merging PR (closes #NN).
