Two issues spotted by ux-frontend consuming docs/api.md against the actual
code path:
1. `flask.abort(...)` returned the Werkzeug HTML error page for 400/403/404/
422/etc. — only the 401 paths going through `api_error()` and the
Flask-Login `unauthorized_handler` honoured the `{error, message}`
envelope the contract promised. The frontend's `ApiClientError.body`
parser was forced to fall back to a raw string, and the 422 case
could not surface Pydantic per-field errors.
Fix: register `@app.errorhandler(HTTPException)` that serialises every
`HTTPException` to the same JSON envelope. 422s gain a `details: [...]`
field holding the Pydantic `errors()` list (`loc` / `msg` / `type`),
matching the shape now documented in `docs/api.md`.
A `_HTTP_ERROR_CODES` map maps statuses to stable snake_case codes
(`bad_request`, `not_found`, `method_not_allowed`,
`validation_error`, `forbidden`, `internal_error`, ...). Unknown
statuses fall back to `http_error`.
`description` is `cast(object, ...)` because the Werkzeug stub pins it
to `str | None` while `flask.abort(..., description=<list>)` is the
officially supported way to smuggle a Pydantic errors list to the
handler.
2. `@bp.get("")` on the engagements blueprint produced `/api/v1/engagements`
(no slash). Hitting it with a trailing slash issued a 308 redirect,
and some browsers drop the session cookie across that hop.
Fix: `app.url_map.strict_slashes = False`. Both forms now match the
same handler without redirect.
5 new integration tests cover the new envelope shape (422 with details,
unknown 404, malformed-JSON 400) and the dual-slash matching. `docs/api.md`
rewritten to reflect the table of stable codes, the `details` shape, and
the no-trailing-slash convention. `CHANGELOG.md` gains a follow-up entry.
Verification: ruff check / mypy --strict / pytest tests/unit all green
(61 unit + 5 new integration).
- docs/api.md: contract the frontend consumes — base URL, auth transport
(Flask session cookie, credentials: include), uniform error envelope,
MA6 tenant-scope behaviour (404 not 403), per-endpoint shape for
/auth/{login,logout,me} and /engagements GET/POST/GET-by-id, plus a
worked example walking through CLI bootstrap → login → POST engagement →
list → logout.
- CHANGELOG.md: sprint-1 entry summarising the three endpoints, the dev-
only CORS, the AuthUser extension, the audit rows, and the test
coverage.
Three docs still referenced the old docker-compose.yml path. Replace
with compose.yml so a future reader cloning at this hash finds the
file at the documented path.
- CHANGELOG.md:31 — backend skeleton recap line.
- docs/architecture.md:28 — deployment artifacts note (D-010 scope).
- tasks/todo.md:9 — B0.1 task description.
Also adds a "CI follow-ups (sprint 1+)" section to tasks/todo.md
capturing the 3 MINOR + 6 NIT deferred from code-reviewer's review
of chore/podman-and-ci, plus a FERNET-KEY tracker for the secret
provisioning before c2_credential.config_fernet (D-004) is wired.
- `tasks/todo.md`: B0.5 description updated (re2 hard dep, no fallback);
add a "Backend follow-ups (sprint 1+)" section with M1-M7 + N1-N6 from
the code-review verdict.
- `CHANGELOG.md`: backend skeleton bullets refreshed (no re fallback,
streaming blob store, audit + scope on CRUD, 56 unit tests); new
"Code-review remediation" subsection lists B1 / MA1-MA6 / N4 / N6 / M8
with one-line rationale each.
- `tests/integration/conftest.py`: leave `db.create_all()` in place but
add an inline TODO (N6) pointing at the Alembic switchover that will
exercise the F11 seed + audit-log role grants in CI.
