feat(keycloak): enable device authorization grant - #156
Conversation
WalkthroughKeycloak client provisioning now enables the OAuth 2.0 device authorization grant alongside PKCE S256. Existing clients are reconciled without losing their settings. Tests, end-to-end checks, and the platform specification cover creation, update, preservation, and idempotence. ChangesKeycloak device authorization grant
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The change enables device authorization for newly provisioned gateway clients while retaining PKCE. Merge-readiness risk is low but warrants owner awareness: malformed client-creation responses may fail later with an empty client ID, and a device-flow test failure can prevent subsequent end-to-end checks from running; normal successful authentication is not affected. Suggested reviewers: Important Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional. ❌ Failed checks (1 error)

The block sends
code_challenge/code_challenge_method=S256and latercode_verifier, but the only assertion iserror == authorization_pending. Keycloak returnsauthorization_pendingbefore user approval regardless of the verifier, so this check passes even if the PKCE parameters were wrong or removed. The comment on line 622 claims the client requires PKCE S256 for every authorization flow, and that claim is untested here.Consider asserting the discriminating case instead: send a device request without
code_challengeand require an error response, or drop the PKCE claim from the comment.Also applies to: 650-657

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
exit 1 aborts the whole suite on a device-grant failure.
Every other check in this script calls fail_test and continues, for example the sandbox checks in section 8 and the namespace GC check in section 11. Here each failure path calls fail_test and then exit 1, so one device-grant problem skips sections 8 through 11 and the final summary. That hides unrelated regressions in the same run. The cleanup trap still runs, so no resources leak.
If the later sections truly cannot run without a device code, guard them with a flag instead of exiting.
