+# CI baseline and deferred lint debt
+
+The backend currently has a broad Ruff rule selection that reports a large backlog of pre-existing import-order, modernization, and bugbear diagnostics. The initial PR CI run found 177 diagnostics across `I`, `UP`, and `B` rules. Those findings are retained as a visible, non-blocking report while the team remediates them in controlled batches.
+
+The blocking Ruff gate is limited to `E`, `F`, and `ASYNC`, which checks core Python errors, undefined names, and async misuse. The workflow separately runs `ruff check --select I,UP,B --exit-zero` so the remaining diagnostics stay visible in CI instead of being silently discarded.
+
+This is an interim baseline, not a claim that the style backlog is resolved. The backend CI enforces Black on changed Python files and runs pytest with the repository root explicitly on `PYTHONPATH`. Both remain blocking gates. Each deferred rule family should be tightened again as its existing violations are corrected.

+## API-key and workspace membership authorization
+
+An API key's effective scopes are the credential ceiling; the resolved active
+workspace membership is a second, independent ceiling. Authorization requires
+both to allow the requested scope. A privileged API key therefore cannot
+elevate a viewer membership.
+
+Workspace membership roles map to permission ceilings as follows:
+
+- `owner` and `admin`: all membership scopes, still limited by the API key.
+- `member` and `service`: the configured `operator` scope set.
+- `viewer`: the configured read-only `viewer` scope set.
+
+The role mapping is applied from the server-resolved `api_key_principals`
+membership, never from a client-supplied workspace or role field.
