// Verify-before-save probe for the Playwright connector.
|
|
//
|
|
// Prints exactly ONE JSON object on stdout:
|
|
// {"ok": bool, "message": string, "details"?: object}
|
|
// Exit code 0 on success, 1 on failure. All diagnostics go to stderr.
|
|
//
|
|
// This connector has no credentials; what can actually break at runtime is
|
|
// the Chromium side: the binary must be present and launchable headless in
|
|
// this environment (system libraries, sandbox restrictions). The probe
|
|
// launches a real headless Chromium on about:blank and closes it.
