eho 67abc58052 feat(openzaak): per-document-type confidentialiteit config (WP-59)
Drives the DRC upload's vertrouwelijkheidaanduiding from a new stamdata
table instead of the hardcoded "openbaar", following the existing
config-as-code pattern (ADR-0004). Adds the referential-integrity check
StamdataValidationTests was missing for the new table.

# WP-59 — Per-document-type confidentialiteit config
Status: done
Phase: 10 — OpenZaak production hardening
## Why
`OpenZaakDocumentSource` hardcodes `vertrouwelijkheidaanduiding` to `"openbaar"` for every
uploaded document, regardless of document type. Real BIG-register documents (diploma's, ID
scans) plausibly need different confidentiality levels. This repo already has a house
pattern for exactly this kind of business-tunable value — stamdata-as-code (ADR-0004) — so
this slice is "apply the existing pattern," not invent a new one.
## Read first
- [ADR-0004 — Stamdata as code](../reference/architecture/0004-stamdata-as-code.md)
- `backend/src/BigRegister.Api/Stamdata/` (an existing table for the shape to imitate)
- `backend/src/BigRegister.Api/Zgw/OpenZaakDocumentSource.cs`
## Decisions (pre-made, don't relitigate)
- Confidentiality level is keyed by document type (whatever type already distinguishes
uploads, e.g. diploma vs. id-bewijs) via a new Stamdata table, using the existing
`StamdataTable.Of<T>` mechanism — not a new ad hoc config format.
- Default/fallback value stays `"openbaar"` if a document type isn't in the table, to
avoid a silent upload failure.
## Files
- `Stamdata/` (new table + validation)
- `Zgw/OpenZaakDocumentSource.cs`
- `StamdataCatalog.cs` (register the new table)
## Steps
1. Add a `DocumentConfidentialiteit` stamdata table (document type →
vertrouwelijkheidaanduiding), validated at build like every other stamdata table
(`StamdataValidationTests`).
2. Register it in `StamdataCatalog` so it's editable via the existing `/beheer/stamdata`
grid.
3. `OpenZaakDocumentSource` looks up the level by document type instead of hardcoding
`"openbaar"`.
## Acceptance criteria
- [x] Confidentiality level for a real upload varies by document type per the new
stamdata table (`identiteit``vertrouwelijk`; everything else → `openbaar`).
- [x] `StamdataValidationTests` cover the new table (a bad edit fails CI, per ADR-0004).
- [x] `/beheer/stamdata` can edit the new table without a code change (existing generic
editor — the `StamdataCatalog` registration is the only wiring needed).
## What actually happened
Implemented mostly as planned — one gap found and closed: the diff as first written
registered `DocumentConfidentialiteit` in `StamdataCatalog` and wired the lookup into
`OpenZaakDocumentSource`, plus a positive test (`identiteit``vertrouwelijk`) and a
fallback test (an unmapped category, `org-logo`, → `openbaar`), but had **no**
`StamdataValidationTests` reference-integrity entry for the new table — the second
acceptance box was unchecked. Added one: a `StamdataRef` resolving every
`documentconfidentialiteit.json` `categoryId` against the real set of document category
ids (`DocumentRules.AllCategoriesFor` across `registratie`/`herregistratie`/`org-template`),
so a typo'd or stale `categoryId` now fails the build instead of silently never matching
(`OpenZaakDocumentSource.ConfidentialiteitFor`'s dictionary lookup would otherwise just
fall back to `"openbaar"` forever with no signal). `org-logo` deliberately stays absent
from the confidentialiteit table (falls back to `"openbaar"`) and correctly still
resolves as a known category — the reference check validates "is this a real category",
not "must every category be configured."
## Verification
`cd backend && dotnet test` (161/161 green, incl. the 2 new `OpenZaakDocumentSourceTests`
+ the new `StamdataValidationTests` reference entry); `dotnet format --verify-no-changes`
clean. Manual: `/beheer/stamdata` shows and edits the new table; an upload for a mapped
document type carries the mapped confidentiality level (test asserted).
## Out of scope
Any UI-facing confidentiality display/change on the citizen side (FE keeps rendering
decisions, not recomputing them, per ADR-0001).
## Risks
None significant — this is a config/data-shape change reusing an established mechanism.
