# 🏥 God Mode (Valhalla) - Health Check & Quality Control

**Date:** December 14, 2025
**System:** God Mode v1.0.0
**Status:** 🟢 **OPERATIONAL**

---

## 1. 🧠 Core Runtime (Node.js)
**Status:** 🟢 **VERIFIED**

*   **Engine:** Node.js (via Astro SSR Adapter)
*   **Startup:** `node ./dist/server/entry.mjs` (Production)
*   **Memory Limit:** `16GB` (Configured in `docker-compose.yml`)
*   **Dependencies:**
    *   `pg` ^8.16.3 (Postgres Driver)
    *   `ioredis` ^5.8.2 (Redis Driver)
    *   `pidusage` ^4.0.1 (Resource Monitoring)

> **Health Note:** The runtime is correctly configured for high-memory operations. Using `entry.mjs` ensures the system runs as a raw Node process, utilizing the full system threads.

---

## 2. ⚡ Database Shim Layer
**Status:** 🟢 **VERIFIED**
**File:** `src/lib/directus/client.ts`

*   **Function:** Translates SDK methods (`readItems`, `createItem`) to raw SQL.
*   **Security:**
    *   ✅ SQL Injection protection via `pg` parameterized queries.
    *   ✅ Collection name sanitization (Regex `^[a-zA-Z0-9_]+$`).
*   **Capabilities:**
    *   `readItems` (Filtering, Sorting, Limits, Offsets)
    *   `createItem` (Batch compatible)
    *   `updateItem`
    *   `deleteItem`
    *   `aggregate` (Count only)
*   **Gaps:** Deep nested relational filtering is **NOT** supported. Complex `_and/_or` logic IS supported.

---

## 3. 🔄 Batch Processor (The Queue)
**Status:** 🟡 **WARNING (Optimization Recommended)**
**File:** `src/lib/queue/BatchProcessor.ts`

*   **Logic:** Custom chunking engine with concurrency control.
*   **Safety:**
    *   ✅ **Standby Awareness:** Checks `system.isActive()` before every batch.
    *   ✅ **Graceful Pause:** Loops every 2000ms if system is paused.
*   **Risk:** The `runWithConcurrency` method keeps all promises in memory. For huge batches (>50k), this puts pressure on GC.
    *   *Reference:* `src/lib/queue/BatchProcessor.ts` Line 46.

---

## 4. 🎛️ System Control Plane
**Status:** 🟢 **VERIFIED**
**File:** `src/lib/system/SystemController.ts`

*   **Monitoring:** Uses `pidusage` to track CPU & RAM.
*   **Mechanism:** Simple state toggle (`active` <-> `standby`).
*   **Reliability:** In-memory state. **Note:** If the Node process restarts, the state resets to `active` (Default).
    *   *Code:* `private state: SystemState = 'active';` (Line 15)

---

## 5. 🛡️ Infrastructure (Docker)
**Status:** 🟢 **VERIFIED**
**File:** `docker-compose.yml`

*   **Ulimit:** `nofile: 65536` (Critical for high concurrency).
*   **Redis:** Included as service `redis`.
*   **Networking:** Internal bridge network for low-latency DB access.

## 📋 Summary & Recommendations

1.  **System is Healthy.** The core architecture supports the documented "Insane Mode" requirements.
2.  **Shim Integrity:** The SQL translation layer is robust enough for standard Admin UI operations.
3.  **Recursion Risk:** Be careful with recursive calls in `BatchProcessor` if extending functionality.
4.  **Restart Behavior:** Be aware that "Standby" mode is lost on deployment/restart.
