📝 WalkthroughWalkthroughThe response server adds a Grok-specific SSE rewrite that removes Codex control frames. The rewrite is enabled for Grok compatibility requests alongside sparse-terminal handling. Tests cover event-name filtering and preservation for ordinary requests. ChangesGrok SSE compatibility
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Grok streams now suppress Codex control frames while ordinary clients retain them, but an SSE block with multiple event fields can still expose a control event to Grok. The fix is narrowly scoped, with additional discriminator-specific coverage needed to protect the compatibility behavior. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@src/server/grok-responses-control-frame.ts`:
- Line 19: Update the event extraction in the SSE response parsing flow to use
the final event: field rather than the first match, matching SSE dispatch
semantics. Ensure control-frame detection uses that final event value, and add a
regression test covering multiple event fields where the last event is a control
frame and the payload is non-JSON or typeless.
In `@tests/responses/responses-snapshot-repair-server.test.ts`:
- Line 346: Add separate regression cases around stubSparseGateway using
GROK_CONTROL_FRAME_EVENTS: one event-only control frame without a matching
payload type and one data-only control frame without an event field, so the
event-name and JSON-type discriminator branches are each tested independently.
