/**
 * scripts/smoke-phase16b3.ts — Phase 16b.3 smoke gate
 *
 * Goal:
 *   1. Boot AidenAgent through the SAME path runInteractiveChat uses
 *      (`buildAgentRuntime`) so PlannerGuard + HonestyEnforcement +
 *      MemoryGuard are all wired exactly as the user sees them.
 *   2. Send "remember that I prefer concise answers" — verify either:
 *        (a) memory_add tool fires AND response acknowledges save, OR
 *        (b) HonestyEnforcement post-loop notice fires
 *            ("NOT VERIFIED" / "verified=false" / "save-attempt failed")
 *   3. Send "what do you remember about me" — response must NOT fabricate
 *      memories that aren't actually in MEMORY.md / USER.md.
 *   4. Print actual response strings so Shiva can verify by eye.
 *
 * Run with:  npx tsx scripts/smoke-phase16b3.ts
 *
 * Requires: at least one Groq API key configured in
 * %LOCALAPPDATA%\\aiden\\.env (slots 1-4 verified working as of 16b.3 prep).
