+
+**AI-Powered Legal & News Intelligence Platform for Kenya**
+
+[](https://go.dev/)
+[](LICENSE)
+[](https://github.com/amaniquery/amaniquery)
+
+AmaniQuery is an AI agent framework designed to democratize access to legal information and civil education in Kenya. Built with a production-ready, Go-based RAG (Retrieval-Augmented Generation) architecture, it provides accurate, contextual answers about Kenya Law and current affairs.

+
+## 🎯 Vision
+
+**Democratizing Access to Information and Civil Education**
+
+AmaniQuery aims to make legal knowledge accessible to every Kenyan citizen by:
+- Providing accurate answers to legal questions in plain language
+- Aggregating and contextualizing news relevant to civic matters
+- Offering a reliable, fast, and secure platform for information retrieval

+# AmaniQuery Render Deployment Guide
+
+This guide details the steps to deploy the AmaniQuery monorepo components to [Render.com](https://render.com).
+
+## Prerequisites
+
+1. **GitHub Repository**: Ensure your code is pushed to a GitHub repository connected to Render.
+2. **Docker**, **Node.js**, and **Go** knowledge.
+3. **Render Account**: Created and ready.
+
+## 1. Database & Infrastructure (Render Postgres & Redis)
+
+Before deploying services, set up your managed data stores.
+
+### PostgreSQL
+
+- **Type**: PostgreSQL
+- **Name**: `amaniquery-db`
+- **Region**: Frankfurt (EU-Central) or nearest.
+- **Environment**:
+ - `POSTGRES_USER`: `amaniquery`
+ - `POSTGRES_DB`: `amaniquery`
+- **Internal Connection URL**: Copy this for use in service env vars.
+
+### Redis
+
+- **Type**: Redis
+- **Name**: `amaniquery-redis`
+- **Max Memory Policy**: `allkeys-lru`
+- **Internal Connection URL**: Copy this (`redis://...`).
+
+## 2. Backend Services (Docker Runtime)
+
+Since AmaniQuery is a monorepo, using **Docker** as the Runtime is recommended for Go services to handle build context correctly (copying `go.mod` from root).
+
+### Common Configuration for All Backend Services
+
+- **Runtime**: Docker
+- **Repository**: `your-repo/amaniquery`
+- **Region**: Same as Database.
+
+| Service Name | Dockerfile Path | Build Context Directory | Env Vars |
+| :--- | :--- | :--- | :--- |
+| `amaniquery-portal` | `services/portal/Dockerfile` | `.` (Root) | `SERVER_HTTP_PORT=8080`, `DB_HOST=...` |
+| `amaniquery-ingestion`| `services/ingestion/Dockerfile`| `.` (Root) | `QDRANT_URL=...`, `RABBITMQ_URL=...` |
+| `amaniquery-voice` | `services/voice/Dockerfile` | `.` (Root) | `OPENAI_API_KEY=...` |
+| `amaniquery-files` | `services/files/Dockerfile` | `.` (Root) | `MINIO_ENDPOINT=...` |
+| `amaniquery-notifications`| `services/notifications/Dockerfile.gateway` | `.` (Root) | `MAILTRAP_API_KEY=...` |
+
+> [!TIP]
+> **Root Directory Setting**: In Render, set "Root Directory" to `.` (default) so Docker builds have access to the full monorepo context.
+
+## 3. Frontend Applications (Static Sites)
+
+We will use the **Static Site** type for frontends, relying on the `Dockerfile` or Render's Native Node build.
+*Recommendation*: Use **Static Site** with Node build command for faster deploys, or **Docker** if you need Nginx customization.
+
+### Option A: Static Site (Native Node - Recommended)
+
+- **Build Command**: `yarn && yarn turbo run build --filter=admin-portal`
+- **Publish Directory**: `frontend/apps/admin/dist`
+- **Root Directory**: `frontend`
+
+### Option B: Docker (Using our new Turbo Dockerfiles)
+
+- **Runtime**: Docker
+- **Dockerfile Path**: `frontend/apps/admin/Dockerfile`
+- **Context**: `frontend` (Important: context is `frontend` subfolder, not root, for these specific Dockerfiles)
+
+| App Name | Build Command (Static) | Publish Dir | Context |
+| :--- | :--- | :--- | :--- |
+| `admin-portal` | `yarn build:admin` | `apps/admin/dist` | `frontend` |
+| `developer-portal` | `yarn build:dev` | `apps/developer-portal/dist` | `frontend` |
+| `web-app` | `yarn build:web` | `apps/web/dist` | `frontend` |
+
+> *Note: You may need to add helper scripts in `frontend/package.json` like `"build:admin": "turbo run build --filter=admin-portal"` to keep commands simple.*
+
+## 4. HuggingFace Spaces (Docker Deployment)
+
+For users preferring HuggingFace Spaces (free tier: 2 vCPU, 16GB RAM, 50GB disk), follow these steps.
+
+### Prerequisites
+
+- HuggingFace Account
+- External Databases (Managed Services):
+ - **PostgreSQL**: Neon.tech (Free Tier available)
+ - **Redis**: Upstash (Free Tier available)
+ - **Qdrant**: Qdrant Cloud (Free Tier available)
+
+### Deployment Steps
+
+1. **Create a New Space**:
+ - Go to [HuggingFace Spaces](https://huggingface.co/new-space)
+ - Enter a name (e.g., `amaniquery`)
+ - Select **Docker** as the Space SDK
+ - Choose "Blank" for the template
+
+2. **Deploy via Script (Recommended)**:
+ - Set `HF_TOKEN` in your local `.env`.
+ - Run: `python scripts/deploy_hf.py agent`
+ - This deploys both the Go Agent and Rust Memory Service in a single container (Sidecar pattern) for maximum efficiency and localhost communication.
+
+3. **Deploy Manually (Alternative)**:
+ - Clone your Space's repository locally.
+ - Copy `deployments/huggingface/Dockerfile.hf` to `Dockerfile` in the root.
+ - Copy `deployments/huggingface/README.md` to the root.
+ - Push to HuggingFace.
+
+4. **Configure Secrets**:
+ - Go to **Settings** -> **Variables and Secrets** in your Space.
+ - Add the secrets listed in `deployments/huggingface/.env.hf.example`.
+
+5. **Status**:
+ - The Space will build and start both `agent-server` and `memory-server`.
+ - The Go agent will automatically connect to the local memory service.
+
+6. **Automated Deployment (Optional)**:
+ We provided a script `scripts/deploy_hf.py` to automate the deployment process.
+
+ **Prerequisites**:
+ - `HF_TOKEN` must be set in your `.env` file (Get it from [HF Settings](https://huggingface.co/settings/tokens)).
+ - The Spaces must be created first (e.g., `AmaniQuery/amaniquery-agent` and `AmaniQuery/amaniquery-memory`).
+
+ **Usage**:
+
+ ```bash
+ # Deploy Agent
+ python scripts/deploy_hf.py agent
+
+ # Deploy Memory Service
+ python scripts/deploy_hf.py memory
+
+ # Deploy Both
+ python scripts/deploy_hf.py all
+ ```
+
+## 5. Environment Variables Checklist
+
+Transfer these from your `env.example` files to Render's "Environment" tab for each service.
+
+- [ ] **Portal**: `DB_HOST`, `DB_PORT`, `DB_USER`, `DB_PASSWORD`, `DB_NAME`, `REDIS_URL`, `JWT_SECRET`
+- [ ] **Voice**: `OPENAI_API_KEY`, `ELEVENLABS_API_KEY`, `REDIS_URL`
+- [ ] **Frontend**: `VITE_API_BASE_URL` (Set this to the `https://...onrender.com` URL of your Portal service).
+
+## 6. Deployment Order
+
+1. **Infrastructure** (Postgres/Redis) - Wait for healthy.
+2. **Backend Services** (Portal, etc.) - Deploy & check logs.
+3. **Frontend Apps** - Deploy & update `VITE_API_BASE_URL` with backend URL.

+# Memory Management System
+
+This package provides a sophisticated memory management system for RAG (Retrieval-Augmented Generation) agents, inspired by the [CoALA paper](https://arxiv.org/abs/2309.02427) on cognitive architectures for language agents.

+
+## Memory Types
+
+| Type | Description | TTL | Use Case |
+|------|-------------|-----|----------|
+| **Episodic** | Specific events/interactions | 7 days | "What did we discuss yesterday?" |
+| **Semantic** | General knowledge/facts | 1 year | "What is the user's preferred language?" |
+| **Procedural** | Learned patterns/skills | 90 days | "User prefers concise answers" |
+| **Temporal** | Time-aware context | 30 days | "What happened last week?" |
+
+## Quick Start
+
+### Basic Usage
+
+```go
+package main
+
+import (
+ "context"
+ "github.com/AmaniQuery/amaniquery/internal/memory"
+)
+
+func main() {
+ // Create configuration
+ config := memory.DefaultMemoryConfig()
+
+ // Create integration (embedder and LLM client required for full functionality)
+ integration, err := memory.NewAgentMemoryIntegration(config, embedder, llmClient)
+ if err != nil {
+ panic(err)
+ }
+ defer integration.Stop()
+
+ // Start background workers
+ integration.Start()
+
+ ctx := context.Background()
+
+ // Store a conversation turn
+ err = integration.StoreConversationTurn(ctx, "user-123", "session-456",
+ "What's the weather like?",
+ "I don't have access to real-time weather data.")
+
+ // Get context for a query
+ memCtx, err := integration.GetContextForQuery(ctx, "user-123", "session-456",
+ "Tell me more about the weather forecast",
+ 4096) // max tokens
+
+ // Use the context in your LLM prompt
+ prompt := buildPrompt(memCtx.ContextWindow, userQuery)
+}
+```
+
+### Using the Memory Worker
+
+```go
+// Create and start the memory worker
+worker := memory.NewMemoryWorker(integration, 4) // 4 worker goroutines
+worker.Start()
+defer worker.Stop()
+
+// Async store (fire and forget)
+worker.AsyncStoreEntry(ctx, &memory.MemoryEntry{
+ Type: memory.SemanticMemory,
+ Content: "User mentioned they live in Kenya",
+ UserID: "user-123",
+ SessionID: "session-456",
+})
+
+// Sync store with result
+result, err := worker.SubmitWorkWithResult(ctx, memory.MemoryWorkItem{
+ Type: memory.WorkStoreEntry,
+ Data: entry,
+})
+```
+
+### GDPR Compliance
+
+```go
+// Export user data (Right to Data Portability)
+export, err := integration.ExportUserData(ctx, "user-123", "admin@example.com")
+jsonData, _ := json.MarshalIndent(export, "", " ")
+
+// Delete user data (Right to be Forgotten)
+err = integration.DeleteUserData(ctx, "user-123", "admin@example.com")
+```
+
+## Components
+
+### `types.go`
+Core type definitions including `MemoryEntry`, `MemoryQuery`, `MemoryManager` interface, and configuration structures.
+
+### `working.go`
+Session-specific working memory with automatic pruning based on size limits.
+
+### `temporal.go`
+Time-aware context tracking with exponential decay scoring for recency-weighted retrieval.
+
+### `context_window.go`
+Smart context window management with multiple formatting styles (Markdown, XML, JSON) and dynamic sizing.
+
+### `orchestrator.go`
+Core memory orchestrator handling concurrent retrieval, LLM-based query analysis, and memory consolidation.
+
+### `consolidation.go`
+Background workers for automatic memory consolidation, TTL cleanup, and retention policy enforcement.
+
+### `gdpr.go`
+GDPR-compliant data management including export (Article 20), deletion (Article 17), and audit logging.
+
+### `local_backend.go`
+In-memory backend for development and testing with full MemoryManager interface implementation.
+
+### `rust_client.go`
+High-performance client for the Rust memory service with binary protocol support and automatic fallback.
+
+### `integration.go`
+High-level integration API connecting memory with the agent orchestrator.
+
+### `worker.go`
+Background worker for async memory operations, compatible with common worker pool patterns.
+
+## Configuration
+
+```go
+config := &memory.MemoryConfig{
+ // Rust service (optional, for production)
+ RustServiceEnabled: true,
+ RustServiceAddress: "localhost",
+ RustServicePort: 9091,
+ ConnectionPoolSize: 10,
+ RequestTimeout: 5 * time.Second,
+
+ // Working memory
+ MaxWorkingMemorySize: 1024 * 1024, // 1MB
+
+ // TTL defaults
+ DefaultTTL: 24 * time.Hour,
+
+ // Consolidation
+ Consolidation: memory.ConsolidationConfig{
+ TurnThreshold: 50, // Consolidate after 50 turns
+ TimeThreshold: 30 * time.Minute,
+ EpisodicRetention: 7 * 24 * time.Hour,
+ SemanticRetention: 365 * 24 * time.Hour,
+ ProceduralRetention: 90 * 24 * time.Hour,
+ },
+}
+```
+
+## Testing
+
+```bash
+# Run all tests
+go test ./internal/memory/...
+
+# Run with verbose output
+go test -v ./internal/memory/...
+
+# Run benchmarks
+go test -bench=. ./internal/memory/...
+```
+
+## Rust Memory Service
+
+For production deployments, the Rust memory service provides sub-millisecond latency:
+
+```bash
+# Start the service stack
+docker-compose -f deployments/docker-compose.memory.yml up -d
+
+# The Go client will automatically connect to the Rust service
+# If unavailable, it falls back to the local backend
+```
+
+See `rust-memory-service/README.md` for more details.
+
+## Metrics
+
+```go
+metrics := integration.GetMetrics()
+// Available metrics:
+// - TotalQueries
+// - TotalStores
+// - AvgRetrievalMs
+// - ConsolidationRuns
+// - SessionsProcessed
+// - TTLDeletions
+// - ActiveWorkingMemories
+```
+
+## Performance Characteristics
+
+| Operation | Local Backend | Rust Service |
+|-----------|---------------|--------------|
+| Store | < 1ms | < 0.5ms |
+| Retrieve | < 5ms | < 1ms |
+| Context Build | < 10ms | < 5ms |
