ci(acl): run the ACL integration test as a Gitea Actions job (refs #46)

New integration job: setup-dotnet + make integration (stack up, OZ_PUBLISH=1 seed,
Integration-category tests, tear down), with on-failure log dump + teardown like
compose-smoke. Documents the job and the new make target in the CI runbook.

+# ADR-0005: Stryker.NET for mutation testing, baseline on the ACL
+
+- **Status:** Accepted
+- **Date:** 2026-06-25
+- **Deciders:** Respellion engineering
+- **Relates to:** S-04b (#47); proposed in #51; supports CLAUDE.md §5 (mutation ratchet) and §3 (Definition of Done)
+
+## Context
+
+CLAUDE.md §5 mandates Stryker on every PR with a **ratchet**: CI fails on a regression
+below the established baseline, and the baseline only ever moves up. §3 lists "mutation
+(ratchet)" as a Definition-of-Done gate for **every** slice. Yet no baseline existed — so,
+strictly, no slice could satisfy that gate. S-04b establishes it.
+
+The ACL is the natural place to set the first baseline: it is the first service with real
+branching logic — `OpenZaakGateway` (HTTP contract, geo CRS headers, error handling),
+`ZgwToken` (HS256 JWT minting), and the `AclService` default-fill mapping. We need a tool
+that:
+
+- mutates C# and runs the existing xUnit suite per mutant,
+- is reproducible (same version locally and in CI, no global install),
+- understands this repo's `.slnx` solution format (used repo-wide),
+- emits a break threshold CI can gate on.
+
+## Decision
+
+**Use [Stryker.NET](https://stryker-mutator.io/docs/stryker-net/) (`dotnet-stryker`),
+pinned as a local dotnet tool**, configured in solution mode against `Acl.slnx`.
+
+- Pinned in `.config/dotnet-tools.json` (v4.15.0); `dotnet tool restore` makes
+  `make mutation` reproducible from a fresh clone, locally and in CI — no global install.
+- **Solution mode** (`stryker-config.json` → `solution: Acl.slnx`) mutates the two projects
+  under test (`Acl.Application`, `Acl.Infrastructure`); `Acl.Api` is untested and skipped.
+  Stryker 4.15 reads `.slnx` directly, so no throwaway `.sln` shim is needed.
+- A `mutation` make target runs it; it is wired into `make ci` and a parallel Gitea Actions
+  `mutation` job, keeping `make ci` an exact mirror of the pipeline.
+
+**Baseline:** writing S-04b's tests surfaced that the ACL suite was thin — the initial
+score was **35%** (survivors: unasserted CRS headers, null guards, error paths, and JWT
+claims). Those tests were strengthened (killing the mutants honestly rather than lowering
+the bar), raising the score to **95%**. The enforced `break` threshold is set to **90%** —
+one-mutant headroom over the ~20-mutant surface, since a single mutant is ≈5%.
+
+## Consequences
+
+- **Positive:** test *strength* is gated, not just coverage; the ratchet protects the ACL's
+  ZGW contract logic; the baseline is repo-wide and ratchets upward per §5.
+- **Cost:** a new dependency (`dotnet-stryker`) and a slower CI job than unit tests (~25 s on
+  the small ACL). Pinned + tool-restored, so reproducible.
+- **One accepted survivor:** a mutation of the empty-response *exception message string*.
+  Asserting exception message text is brittle and the behaviour (type + control flow) is
+  unchanged — treated as an equivalent mutant, not a test gap.
+- **Commitment:** later slices ratchet the threshold up deliberately, never down (§5). New
+  services add their own mutation run as they gain branching logic (BFF, Domain, …).
+- **Replaceable by:** no realistic .NET alternative — Stryker.NET is the tool §5 already
+  names; the fallback is no mutation testing, which §5 forbids.
+
+## Alternatives considered
+
+- **Global `dotnet tool install -g`** — rejected: not reproducible/pinned per clone; the
+  local manifest gives every checkout and the CI runner the same version.
+- **Mutate the whole `register-referentie.slnx`** — rejected for this slice: scopes the
+  baseline to services with no logic yet (BFF skeleton), diluting the signal. Each service
+  opts in as it gains logic.
+- **Application-only scope** — rejected: would leave `Acl.Infrastructure`'s HTTP/JWT logic —
+  the riskiest code — unguarded by the ratchet.
+- **Coverage gate instead of mutation** — rejected: line coverage does not measure whether
+  tests would *catch* a regression; that is the whole point of §5.

+# ADR-0006: Provision the ACL integration test against the compose stack
+
+- **Status:** Accepted
+- **Date:** 2026-06-29
+- **Deciders:** Respellion engineering
+- **Relates to:** S-04a (#46); proposed in #53; builds on ADR-0001 (loose coupling), ADR-0002 (catalogus design), ADR-0003 (default-fill); supports CLAUDE.md §11 (integration tests via real containers)
+
+## Context
+
+S-04 delivered the ACL's one operation — `OpenZaakGateway.OpenZaakAsync` — with unit
+tests against a stubbed `HttpMessageHandler` and a Reqnroll scenario over an in-memory
+stand-in. The deferred S-04 acceptance criterion (S-04a) is the one a stub cannot meet:
+
+> Integration test using Testcontainers against real OpenZaak passes.
+
+The test must drive the gateway against a **real** OpenZaak — real ZGW JWT auth, the real
+`POST /zaken/api/v1/zaken` contract, real CRS handling — and assert a zaak comes back.
+
+Two ways to stand OpenZaak up were considered (the issue's open question): (a) a full
+**Testcontainers** graph started by the test, or (b) target the **running compose stack**
+the repo already defines (`infra/openzaak/docker-compose.yml`, `make openzaak-up`).
+
+Investigation reversed the initially-favoured Testcontainers option:
+
+1. **Testcontainers .NET has no docker-compose support.** OpenZaak needs PostGIS + Redis +
+   a `setup_configuration` one-shot (the JWT client) + the API. Honouring "full graph" would
+   mean re-implementing that five-service stack — init ordering, the config volume, health
+   gating — by hand in C#, duplicating the maintained compose file and rotting with it. That
+   rubs against CLAUDE.md §13 ("if a test is hard to write, the design is wrong").
+2. **The test cannot be hermetic anyway.** OpenZaak's Zaken API rejects a zaak against a
+   *concept* zaaktype (`not-published`), and a *published* zaaktype requires ≥1 resultaattype,
+   which OpenZaak validates by fetching the external **Selectielijst** reference API
+   (`selectielijst.openzaak.nl`). So a real zaak POST already depends on outbound internet
+   from the OpenZaak container — the self-containment that motivated Testcontainers is lost
+   regardless of how the containers are started.
+
+## Decision
+
+**The ACL integration test targets the running compose stack; it does not start containers
+itself. No new test dependency is added.**
+
+- A gated test project `Acl.IntegrationTests` (`[Trait("Category","Integration")]`) talks to
+  OpenZaak with a plain `HttpClient`, reusing the same endpoint + JWT-client config the seed
+  uses (`OZ_BASE` / `OZ_CLIENT_ID` / `OZ_SECRET`, defaulting to the local stack). It locates
+  the published `BIG-REGISTRATIE` zaaktype via the Catalogi API and exercises the real
+  `OpenZaakGateway` against it.
+- **The lane is kept out of the fast checks.** `make unit` runs with
+  `--filter "Category!=Integration"`; Stryker is pinned to `Acl.Tests` (`test-projects`), so
+  neither the unit nor the mutation lane needs a live stack. A new `make integration` target
+  brings the stack up, seeds, runs the lane, and always tears down — mirrored by a Gitea
+  Actions `integration` job. This matches `make` being the single source of truth (ADR-0005).
+- **Publishing is opt-in in the seed.** `infra/openzaak/seed_catalogus.py` gains an
+  `OZ_PUBLISH=1` path that adds the relations OpenZaak's publish requires — two statustypen
+  (begin/eind), a roltype, and a resultaattype whose Selectielijst procestype is matched onto
+  the zaaktype — then publishes. The default seed (S-01 / ADR-0002) still leaves the zaaktype
+  a concept; only `make integration` flips the switch.
+
+## Consequences
+
+- **Positive:** a small, honest test over the real ZGW contract with no bespoke orchestration
+  to maintain; the compose stack is exercised exactly as operators run it; no new dependency.
+- **It caught a real bug.** The gateway sent the zaak body via `JsonContent` without a
+  `Content-Length`, so .NET framed it as `Transfer-Encoding: chunked`, which OpenZaak's uwsgi
+  rejects with 400. A stubbed handler accepts either framing, so only a real OpenZaak surfaced
+  it. Fixed by buffering the body (`LoadIntoBufferAsync`); guarded in the fast lane by a unit
+  test asserting a `Content-Length` is set. This is the concrete justification for §11's
+  integration tier.
+- **External dependency:** the integration job needs the OpenZaak container to reach
+  `selectielijst.openzaak.nl`. It is a stable public reference API (the same one OpenZaak uses
+  in production) but it is a network touchpoint, and a CI environment without egress would need
+  a local Selectielijst service or a recorded fixture. `OZ_SELECTIELIJST` overrides the base URL.
+- **Cost:** the lane needs the stack up first; CI runs it as a dedicated job (Docker + dotnet +
+  python3), separate from the fast lanes.
+
+## Alternatives considered
+
+- **Full Testcontainers graph** — rejected: re-implements the compose stack in C# (brittle,
+  duplicative) for no hermeticity gain, since the Selectielijst dependency remains.
+- **Single OpenZaak container (sqlite/locmem)** — rejected: diverges from the real
+  PostGIS-backed, Redis-cached deployment; the Zaken API is a geo API and the divergence would
+  undermine the contract the test exists to verify.
+- **Mock OpenZaak / record-replay** — rejected: that is what the existing stubbed-handler unit
+  tests already do; it cannot exercise the real contract, and would not have caught the chunked
+  body bug.

+
+```bash
+make mutation     # dotnet tool restore + dotnet stryker on the ACL
+```
+
+Config lives in [`services/acl/stryker-config.json`](../../services/acl/stryker-config.json).
+It runs in **solution mode** against `Acl.slnx`, mutating the two projects under test
+(`Acl.Application`, `Acl.Infrastructure`); `Acl.Api` has no tests and is skipped.
+
+**Baseline (the ratchet):** the ACL is the first service with branching logic, so it
+sets the repo-wide baseline. Observed score **95%**; enforced `break` threshold **90%**
+(one-mutant headroom over the ~20-mutant surface). Stryker exits non-zero — failing the
+job — when the score drops below `break`. Per §5 the baseline only moves **up**, and only
+as a slice's stated outcome; never lower it. New services add their own mutation run as
+they gain logic.
+
+The HTML report is written to `services/acl/StrykerOutput/<timestamp>/reports/` (git-ignored);
+open it to see survived vs. killed mutants.
+
+In CI the `mutation` job publishes that report as the **`acl-mutation-report`** artifact
+(download it from the run's summary page). The upload step uses `if: always()`, so the
+report is available even when the ratchet *fails* — which is exactly when you want to inspect
+the survivors. It is the repo's first use of `actions/upload-artifact`, pinned to **`@v3`**:
