+# God Mode - Technical Stack & CTO Log
+
+## 🏗 Technical Architecture
+
+### Core Stack
+- **Framework:** Astro 4.0 (Server-Side Rendering mode)
+- **Runtime:** Node.js 20+
+- **Language:** TypeScript
+- **Styling:** TailwindCSS with custom "God Mode" palette
+
+### Backend & Data
+- **Database:** PostgreSQL 16 (on Coolify)
+- **ORM:** Native `pg` queries (raw SQL for performance) + Custom Migration scripts
+- **Queue:** BullMQ (Redis-backed) for async content generation
+- **Caching:** Redis (shared with queue)
+
+### Content Engine
+- **Spintax:** Custom recursive resolver (`{A|B|{C|D}}` support)
+- **Variables:** Handlebars-style expansion (`{{CITY}}`)
+- **Uniqueness:** SHA-256 hashing of variation paths to prevent duplicates
+
+---
+
+## 📔 CTO Log & Decision Record
+
+### 2025-12-15: The "God Mode" Pivot
+**Decision:** Shifted from standard CMS to "God Mode" - a high-throughput, automated content engine.
+**Rationale:** The previous "Spark" manually managed content was too slow. We need to generate thousands of local SEO pages programmatically.
+**Implementation:**
+- Built `SpintaxResolver` to deterministically generate content.
+- Created `variation_registry` to ensure we never publish the same article twice (Google Duplicate Content penalty prevention).
+- Implemented `BullMQ` to handle the heavy processing load off the main web thread.
+
+### 2025-12-15: Architecture Standardization
+**Decision:** Enforce strict folder structure for Admin UI.
+**Rationale:** The admin panel grew to 70+ pages. Direct file-based routing in `src/pages/admin` mirrored by `src/api` ensures maintainability.
+**Standards:**
+- All lists must use the standard `StatCard` and Table components.
+- All pages must have inline `<DevStatus>` if they aren't fully wired up.
+
+### 2025-12-15: Production Readiness
+**Decision:** Multi-stage Docker build.
+**Rationale:** Build times were increasing. We separated dependencies installation from the build process in `Dockerfile` to leverage layer caching.
+**Strategy:**
+- We commit `package-lock.json` strictly.
+- We run linting *before* build in CI.
+
+---
+
+## 🛠 Feature Roadmap
+
+### Phase 8 (Next)
+- [ ] Connect `sites` table to Admin UI.
+- [ ] Implement `campaign_masters` fetch logic.
+- [ ] Wire up the `generation_jobs` queue monitor.
+
+### Future
+- [ ] **Vector Database:** Add `pgvector` for semantic search of content fragments.
+- [ ] **LLM Integration:** Add OpenAI/Anthropic step to `contentGenerator` worker for non-spintax dynamic writing.
+- [ ] **Multi-Tenant:** Allow multiple users to have their own "God Mode" instances (requires tenant_id schema update).
