After the React-codegen rework, ran the full e2e harness against the
docker-stack backend. Surfaced and fixed real friction:
mizan-base/src/index.ts (kernel):
- MizanError now parses both error envelopes — the FastAPI shape
({"error": {"code", "message", "details"}}) and the Django shape
({"error": true, "code", "message", "details"}). Exposes .code and
.details on the thrown error so consumer code can branch on them.
This was needed for the harness's `instanceof MizanError && error.code
=== 'NOT_FOUND'` pattern to work; the previous MizanError only carried
status + raw body, leaving callers to parse the body themselves.
examples/django-react-site/Dockerfile.test:
- Backend image now copies and installs cores/mizan-python before
installing mizan-django (which imports from mizan_core after the
Layer 1 extraction).
harness/src/fixtures.tsx:
- useRun helper updated for the new mutation-hook shape: pulls
{ mutate } off the hook result instead of treating the hook return
as a callable. Same for ValidationError fixture.
mizan.spec.ts:
- DjangoError → MizanError (kernel error class is backend-agnostic).
- Form tests removed (forms codegen deferred per Blazr scope).
- Channel test marked test.skip (channels deferred per Blazr scope).
.gitignore: ignore Playwright test-results/.
Final verification across all surfaces:
- mizan-core unit: 15/15
- mizan-django unit: 348 pass, 21 skip
- mizan-fastapi unit: 11/11
- mizan-ts edge-compat: 34/34 (cross-language HMAC pin)
- harness e2e (Playwright): 14/15 (1 skip = channels deferred)
