/**
|
|
* Unit tests for browse/src/security-sidecar-client.ts.
|
|
*
|
|
* Tests the IPC client's behavior against a fake sidecar (a tiny Node
|
|
* script we spawn) — verifies request/response id correlation, timeout,
|
|
* payload cap, malformed-response handling, and circuit-breaker tripping.
|
|
*
|
|
* Does NOT exercise the real classifier — that lives behind the model
|
|
* download and is covered by the existing security-classifier tests + the
|
|
* E2E browser security suite.
