In `@python/packages/jumpstarter/jumpstarter/exporter/exporter.py`:
- Around line 653-655: Update Exporter.rotate_token() so exceptions from
on_token_rotated, including awaited callbacks, are caught and reported
separately after the credential Secret is updated, rather than propagating into
_token_refresh_loop()'s generic retry path. Ensure callback failures do not
trigger another RotateToken call while preserving the normal token-rotation
result.

- Line 47: Add a synchronous token-rotation callback test alongside the existing
AsyncMock coverage in the exporter token refresh tests. Use a callback that
records the token and returns None, then assert rotate_token() invokes it once
with the expected token and completes normally, covering the non-awaitable
branch of on_token_rotated.

- Around line 194-195: The token refresh test must verify that
_token_refresh_loop() attempts the unimplemented RotateToken RPC, not only that
the token remains unchanged. Assert the mocked RPC was awaited exactly once
while preserving the existing unchanged-token assertion.
- Around line 160-161: Update the test around _token_refresh_loop() to bind the
anyio.move_on_after(0.5) cancel scope and assert cancel_called after the scope
exits, ensuring the loop remains active until the next refresh interval rather
than returning after one rotation.

Included review availability: Your plan provides up to 2 included reviews per hour; 0 remain after this review.
- Add RotateToken RPC to ControllerService in protocol/proto/jumpstarter/v1/jumpstarter.proto. - Implement RotateToken in ControllerService to generate a new signed token and update the exporter Secret. - Regenerate jumpstarter.v1 protobuf bindings for Go and Python. - Add token_refresh helper to decode JWT claims and calculate renewal lead times and sleep intervals. - Add _token_refresh_loop in Exporter to automatically request a new token before expiry. - Wire on_token_rotated callback in ExporterConfigV1Alpha1 to update in-memory state and persist to disk. - Add comprehensive unit tests in controller and python packages.
Add TokenExpiresAt timestamp and TokenExpiring condition to Exporter status, matching the Client status implementation. This enables downstream systems (Prometheus, alerting, kubectl) to detect exporter tokens approaching expiry before connectivity is lost. Also emit CredentialCreated and TokenExpiringSoon events, display Token Expires in kubectl get exporters, and ensure ExporterReconciler periodically requeues to track expiry even when an exporter is offline.
