/**
 * agent-wsl-lucas.spec.ts — DoD Quality Triada test suite for issue 0144 / flow 0009.
 *
 * Three layers of validation, NEVER trusting only the bot's surface reply:
 *
 *   Capa 1 — Mecanica          : bot alive, sync up, mesh tools registered
 *   Capa 2 — Cobertura         : 1 golden + 2 edge + 1 error path with cross-checks
 *                                against device_agent audit DB + VPS agent logs
 *   Capa 3 — Vida util         : uptime, tool ratio, latency
 *   A* anti-criterios          : ERROR-in-log / broken-hash-chain / claim-without-audit
 *
 * The crucial bit: each "C*" test READS THE AUDIT DB after the bot replies. If
 * the bot says "I ran echo HOLA-E2E" but there is no shell.exec entry in
 * /tmp/device_audit.db, the test fails (A3 anti-criterion: hallucinated tool use).
 *
 * Run only this spec:
 *   cd e2e && npx playwright test agent-wsl-lucas.spec.ts
 *
 * Required env (in e2e/.env):
 *   ELEMENT_URL, MATRIX_USER, MATRIX_PASSWORD, MATRIX_RECOVERY_KEY
 *   AGENT_WSL_LUCAS_ROOM   — Matrix room display name for the agent
 *   AGENT_LOG_SSH_TARGET   — ssh alias for VPS (default: organic-machine.com)
 *   DEVICE_AUDIT_DB        — path to device_agent audit (default: /tmp/device_audit.db)
