/**
 * #2557 / ENG-OV9: pins the dead-shield removal AND the live L4 wiring.
 *
 * The removed surface: /health's `security` field read getStatus(), whose
 * only data source (~/.gstack/security/session-state.json) lost its only
 * writer when sidebar-agent.ts was ripped — so /health reported a permanent
 * 'inactive' or, wherever an old state file survived, a stale FALSE-GREEN
 * 'protected' ("no threats detected" when the real state was "not
 * measured"). Same fail-open class as #2026.
 *
 * The kept surface (ENG-OV9): security.ts is NOT dead — server.ts's
 * /pty-inject-scan path is the live L4 consumer (sidecar scan + URL
 * blocklist + datamark envelope), and security.ts's pure combiner/canary
 * exports stay. This test pins both directions so a future "cleanup" can't
 * silently take the live half, and a future re-feed of /health.security
 * from LIVE signals (isSidecarAvailable, content filters) must update this
 * test deliberately rather than resurrect the state-file path.
 *
 * Source-level, same style as windows-spawn-hide.test.ts.
