The 5s timeout on `statusFuture.get(...)` is because the 200 response opens an infinite SSE stream; `BodyHandlers.ofString()` waits for body completion that never comes. + +Confirm by inspecting `JwtAuthenticationFilter` and `JwtService.JwtValidationResult` to see whether `subject()` or an equivalent agent-id claim is available on the result.

The JWT subject doesn't match the path id. + +If Step 5.3 finds the auto-heal bug, these tests may also benefit: when JWT subject ≠ path id, these tests currently rely on auto-heal too (since the path id was freshly registered through the `/register` endpoint, but the JWT they use in the SSE request is a *different* agent's JWT). + +Wait — re-check: `registerAgent` in the test uses `bootstrapHeaders()` (not JWT).
