 # CLAUDE.md
 
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+This file provides guidance to Claude Code and other AI assistants working with this repository.
 
 ## Project Overview
 
-Memvid is a Python library for QR code video-based AI memory that enables:
-- Chunking and encoding text data into QR code videos
-- Fast semantic search and retrieval from QR videos
-- Conversational AI interface with context-aware memory
+Memvid is a Rust library that provides a single-file memory layer for AI agents. It packages documents, embeddings, search indices, and metadata into a portable `.mv2` file.
 
-## Key Architecture
+## Architecture
 
 ### Core Components
-- **MemvidEncoder** (memvid/encoder.py): Handles text chunking and QR video creation
-- **MemvidRetriever** (memvid/retriever.py): Fast semantic search, QR frame extraction, context assembly
-- **MemvidChat** (memvid/chat.py): Manages conversations, context retrieval, and LLM interface
-- **IndexManager** (memvid/index.py): Embedding generation, storage, and vector search
 
-### Data Flow
-1. Text chunks → Embeddings → QR codes → Video frames
-2. Query → Semantic search → Frame extraction → QR decode → Context
-3. Context + History → LLM → Response

 ## Development Commands
 
 ```bash
-# Create and activate virtual environment
-python -m venv .memvid
-source .memvid/bin/activate  # On macOS/Linux
+# Build
+cargo build
+cargo build --release
 
-# Install dependencies

 ```
 
-## Key Dependencies
-- qrcode, Pillow: QR generation
-- opencv-python: Video processing
-- pyzbar: QR decoding
-- sentence-transformers: Semantic embeddings
-- numpy: Vector operations
-- openai: LLM integration (pluggable)
+## Key APIs
 
-## Performance Requirements
-- Retrieval (search + QR decode) must be < 2 seconds for 1M chunks
-- Use batching and parallel processing for frame extraction
-- Implement caching for hot frames and common queries
+```rust
+// Create/Open
+let mut mem = Memvid::create("file.mv2")?;
+let mut mem = Memvid::open("file.mv2")?;
 
-## Implementation Notes
-- Vector DB options: FAISS, Annoy, or Chroma for scalability
-- LLM backend should be pluggable (OpenAI, Claude, Gemini, local)
-- Thread/process pools for parallel QR decoding
-- Disk-based index for large-scale deployments
+// Write
+mem.put_bytes(content)?;
+mem.put_bytes_with_options(content, options)?;
+mem.commit()?;
+
+// Search
+mem.search(SearchRequest { query, top_k, .. })?;
+mem.timeline(TimelineQuery::default())?;
+
+// Verify
+Memvid::verify("file.mv2", deep)?;
+```
+
+## Feature Flags
+
+| Feature | Purpose |
+|---------|---------|
+| `lex` | Full-text search (default) |
+| `vec` | Vector similarity search |
+| `clip` | CLIP image embeddings |
+| `whisper` | Audio transcription |
+| `encryption` | AES-256-GCM encryption |
+
+## Code Style
+
+- Follow Rust idioms and best practices
+- Use `thiserror` for error types
+- Use `tracing` for logging
+- Add doc comments for public APIs
+- Write tests for new functionality
+
+## Important Notes
+
+- Single-file design: Never create sidecar files
+- Crash safety: All writes go through WAL
+- Append-only: Frames are immutable once committed
+- No async: Library is synchronous for simplicity

+1. Push to your fork:
    ```bash
    git push origin feature/your-feature-name
    ```
 
-6. **Create a Pull Request** on GitHub
+2. Open a Pull Request on GitHub
 
-## 📝 Code Style
+3. Fill out the PR template completely
 
-- Follow PEP 8 guidelines
-- Use meaningful variable and function names
-- Add docstrings to all functions and classes
-- Keep functions focused and small
-- No commented-out code
+4. Wait for review and address feedback
 
-## 🧪 Testing
+## Code Style
 
-- Write tests for new features
-- Ensure all tests pass before submitting PR
-- Aim for high test coverage
-- Test edge cases
+### Rust Guidelines
 
-## 📚 Documentation
+- Follow standard Rust idioms and conventions
+- Use `rustfmt` for formatting (`cargo fmt`)
+- Use `clippy` for linting (`cargo clippy`). We maintain a **zero-warning policy**.
+- Prefer explicit types for public APIs
+- Use `thiserror` for error definitions
 
-- Update README.md if adding new features
-- Add docstrings following Google style
-- Include usage examples for new functionality
-- Update CLAUDE.md if changing core architecture
+### Linting & Safety
 
-## 🐛 Reporting Issues
+We enforce strict linting to ensure safety and portability:
 
-When reporting issues, please include:
-- Python version
+1.  **Zero Warnings**: CI will fail on any warning. Run `cargo clippy --workspace --all-targets -- -D warnings` locally.
+2.  **No Panics**: `unwrap()` and `expect()` are **denied** in library code. Use `Result` propagation (`?`) or graceful error handling. They are allowed in `tests/`.
+3.  **No Truncation**: `cast_possible_truncation` is denied. Use `try_from` when converting `u64` to `usize`/`u32`.
+4.  **Exceptions**: We allow pragmatic lints (e.g., `cast_precision_loss` for ML math) in `src/lib.rs`. Do not add global `#![allow]` without discussion.
+
+### Documentation
+
+- Add doc comments (`///`) to all public functions, structs, and modules
+- Include examples in doc comments where helpful
+- Keep comments concise and up-to-date
+
+### Testing
+
+- Write unit tests for new functionality
+- Place tests in the same file using `#[cfg(test)]` module
+- Integration tests go in the `tests/` directory
+- Aim for high coverage of edge cases
+

+## Feature Flags
+
+When adding new functionality, consider if it should be behind a feature flag:
+
+```toml
+[features]
+my_feature = ["dep:some-dependency"]
+```
+
+This keeps the default build lean and fast.

+## Header (4096 bytes)
+
+The header occupies the first 4 KB of the file.
+
+| Offset | Size | Field | Description |
+|--------|------|-------|-------------|
+| 0 | 4 | `magic` | `MV2\0` (0x4D 0x56 0x32 0x00) |
+| 4 | 2 | `version` | Format version (little-endian) |
+| 6 | 1 | `spec_major` | Spec major version (2) |
+| 7 | 1 | `spec_minor` | Spec minor version (1) |
+| 8 | 8 | `footer_offset` | Byte offset to TOC |
+| 16 | 8 | `wal_offset` | Byte offset to WAL (always 4096) |
+| 24 | 8 | `wal_size` | WAL region size in bytes |
+| 32 | 8 | `wal_checkpoint_pos` | Last checkpointed sequence |
+| 40 | 8 | `wal_sequence` | Current WAL sequence number |
+| 48 | 32 | `toc_checksum` | SHA-256 of TOC segment |
+| 80 | 4016 | reserved | Zero-filled, reserved for future use |
+
+All multi-byte integers are little-endian.
+
+## Write-Ahead Log (WAL)
+
+The embedded WAL provides crash recovery. It starts at byte 4096 and has a capacity determined by the file's target size:
+
+| File Capacity | WAL Size |
+|---------------|----------|
+| < 100 MB | 1 MB |
+| < 1 GB | 4 MB |
+| < 10 GB | 16 MB |
+| >= 10 GB | 64 MB |
+
+### WAL Entry Format
+
+```
+┌──────────────────────────────────────┐
+│ sequence    │ 8 bytes (u64 LE)       │
+│ entry_type  │ 1 byte                 │
+│ payload_len │ 4 bytes (u32 LE)       │
+│ payload     │ variable               │
+│ checksum    │ 4 bytes (CRC32)        │
+└──────────────────────────────────────┘
+```
+
+Entry types:
+- `0x01` - Frame append
+- `0x02` - Frame update
+- `0x03` - Frame delete (tombstone)
+- `0x04` - Index update
+
+### Checkpoint Behavior
+
+- Checkpoint triggers at 75% WAL occupancy or every 1,000 transactions
+- Checkpoint flushes WAL entries to data segments
+- `seal()` forces immediate checkpoint
+- Recovery replays entries with `sequence > wal_checkpoint_pos`
+
+## Frame Structure
+
+Each frame represents a single piece of content.
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `frame_id` | u64 | Unique identifier (monotonic) |
+| `uri` | String | Hierarchical path (`mv2://path/to/doc`) |
+| `title` | String? | Optional display title |
+| `created_at` | u64 | Unix timestamp (seconds) |
+| `encoding` | u8 | Content encoding (see below) |
+| `payload` | bytes | Compressed content |
+| `payload_checksum` | [u8; 32] | SHA-256 of uncompressed payload |
+| `tags` | Map<String, String> | User-defined key-value pairs |
+| `status` | u8 | 0=active, 1=tombstoned |
+
+### Encoding Types
+
+| Value | Name | Description |
+|-------|------|-------------|
+| 0 | Raw | Uncompressed bytes |
+| 1 | Zstd | Zstandard compression |
+| 2 | Lz4 | LZ4 compression |
+
+## Data Segments
+
+Frames are grouped into segments for efficient storage and retrieval.
+
+### Segment Header
+
+```
+┌──────────────────────────────────────┐
+│ magic         │ 4 bytes              │
+│ version       │ 2 bytes              │
+│ segment_type  │ 1 byte               │
+│ frame_count   │ 4 bytes              │
+│ compressed    │ 1 byte (bool)        │
+│ checksum      │ 32 bytes             │
+└──────────────────────────────────────┘
+```
+
+Segment types:
+- `0x01` - Data segment (frames)
+- `0x02` - Lex index segment
+- `0x03` - Vec index segment
+- `0x04` - Time index segment
+
+## Time Index
+
+The time index enables chronological queries and time-travel.
+
+### Time Index Entry
+
+| Field | Size | Description |
+|-------|------|-------------|
+| `frame_id` | 8 | Frame identifier |
+| `timestamp` | 8 | Unix timestamp |
+| `offset` | 8 | Byte offset in data segment |
+
+Magic: `MVTI` (0x4D 0x56 0x54 0x49)
+
+## Lex Index (Full-Text Search)
+
+When the `lex` feature is enabled, the file contains a Tantivy index segment.
+
+Indexed fields:
+- `body` - Full text content
+- `title` - Document title
+- `uri` - Document URI
+- `tags` - Flattened tag values
+
+Supports:
+- BM25 ranking
+- Phrase queries
+- Boolean operators
+- Date range filters
+
+## Vec Index (Vector Search)
+
+When the `vec` feature is enabled, the file contains an HNSW index segment.
+
+| Parameter | Value |
+|-----------|-------|
+| Dimensions | 384 (BGE-small) |
+| Distance | Cosine similarity |
+| M | 16 |
+| ef_construction | 200 |
+
+## Table of Contents (TOC)
+
+The TOC is the final segment, pointed to by `footer_offset` in the header.
+
+```
+┌──────────────────────────────────────┐
+│ magic         │ "MVTC"               │
+│ version       │ 2 bytes              │
+│ segment_count │ 4 bytes              │
+│ segments[]    │ SegmentDescriptor[]  │
+│ manifests     │ IndexManifests       │
+│ checksum      │ 32 bytes             │
+└──────────────────────────────────────┘
+```
+
+### Segment Descriptor
+
+| Field | Size | Description |
+|-------|------|-------------|
+| `segment_type` | 1 | Type identifier |
+| `offset` | 8 | Byte offset in file |
+| `length` | 8 | Segment size in bytes |
+| `checksum` | 32 | SHA-256 of segment |
+
+## URI Scheme
+
+All content is addressable via `mv2://` URIs:
+
+```
+mv2://[track/][path/]name
+```
+
+Examples:
+- `mv2://meetings/2024-01-15`
+- `mv2://docs/api/reference.md`
+- `mv2://media/photo.png`
+
+## Invariants
+
+1. **Single-file guarantee**: No `.wal`, `.shm`, `.lock`, or other sidecar files
+2. **Append-only frames**: Existing frames are never modified in place
+3. **Determinism**: Same API calls produce identical bytes
+4. **Crash safety**: WAL ensures durability across unexpected termination
+5. **Self-describing**: TOC contains all metadata needed to parse the file
+
+## Version History
+
+| Version | Changes |
+|---------|---------|
+| 2.1 | Current version. Embedded WAL, temporal track support |
+| 2.0 | Single-file format, removed external indices |
+| 1.x | Legacy format (deprecated) |

+## What is Memvid?
 
-Created by [Olow304](https://github.com/olow304) and the Memvid community.
+Memvid is a portable AI memory system that packages your data, embeddings, search structure, and metadata into a single file.
 
-Built with ❤️ using:
-- [sentence-transformers](https://www.sbert.net/) - State-of-the-art embeddings for semantic search
-- [OpenCV](https://opencv.org/) - Computer vision and video processing
-- [qrcode](https://github.com/lincolnloop/python-qrcode) - QR code generation
-- [FAISS](https://github.com/facebookresearch/faiss) - Efficient similarity search
-- [PyPDF2](https://github.com/py-pdf/pypdf) - PDF text extraction
+Instead of running complex RAG pipelines or server-based vector databases, Memvid enables fast retrieval directly from the file.
 
-Special thanks to all contributors who help make Memvid better!
+The result is a model-agnostic, infrastructure-free memory layer that gives AI agents persistent, long-term memory they can carry anywhere.
+
+    
+## What are Smart Frames?
+
+Memvid draws inspiration from video encoding, not to store video, but to **organize AI memory as an append-only, ultra-efficient sequence of Smart Frames.**
+
+A Smart Frame is an immutable unit that stores content along with timestamps, checksums and basic metadata.
+Frames are grouped in a way that allows efficient compression, indexing, and parallel reads.
+
+This frame-based design enables:
+
+-   Append-only writes without modifying or corrupting existing data
+-   Queries over past memory states
+-   Timeline-style inspection of how knowledge evolves
+-   Crash safety through committed, immutable frames
+-   Efficient compression using techniques adapted from video encoding
+
+The result is a single file that behaves like a rewindable memory timeline for AI systems.
+
+
+## Core Concepts
+
+-   **Living Memory Engine**
+    Continuously append, branch, and evolve memory across sessions.
+
+-   **Capsule Context (`.mv2`)**
+    Self-contained, shareable memory capsules with rules and expiry.
+
+-   **Time-Travel Debugging**
+    Rewind, replay, or branch any memory state.
+
+-   **Smart Recall**
+    Sub-5ms local memory access with predictive caching.
+
+-   **Codec Intelligence**
+    Auto-selects and upgrades compression over time.
+
+
+## Use Cases
+
+Memvid is a portable, serverless memory layer that gives AI agents persistent memory and fast recall. Because it's model-agnostic, multi-modal, and works fully offline, developers are using Memvid across a wide range of real-world applications.
+
+-   Long-Running AI Agents
+-   Enterprise Knowledge Bases
+-   Offline-First AI Systems
+-   Codebase Understanding
+-   Customer Support Agents
+-   Workflow Automation
+-   Sales and Marketing Copilots
+-   Personal Knowledge Assistants
+-   Medical, Legal, and Financial Agents
+-   Auditable and Debuggable AI Workflows
+-   Custom Applications

+
+### Usage in Code
+
+```rust
+use memvid_core::text_embed::{LocalTextEmbedder, TextEmbedConfig};
+use memvid_core::types::embedding::EmbeddingProvider;
+
+// Use default model (BGE-small)
+let config = TextEmbedConfig::default();
+let embedder = LocalTextEmbedder::new(config)?;
+
+let embedding = embedder.embed_text("hello world")?;
+assert_eq!(embedding.len(), 384);
+
+// Use different model
+let config = TextEmbedConfig::bge_base();
+let embedder = LocalTextEmbedder::new(config)?;
+```
+
+See `examples/text_embedding.rs` for a complete example with similarity computation and search ranking.
+
+### Model Consistency
+
+To prevent accidental model mixing (e.g., querying a BGE-small index with OpenAI embeddings), you can explicitly bind your Memvid instance to a specific model name:
+
+```rust
+// Bind the index to a specific model.
+// If the index was previously created with a different model, this will return an error.
+mem.set_vec_model("bge-small-en-v1.5")?;
+```
+
+This binding is persistent. Once set, future attempts to use a different model name will fail fast with a `ModelMismatch` error.
+
+
+
+## API Embeddings (OpenAI)
+
+The `api_embed` feature enables cloud-based embedding generation using OpenAI's API.
+
+### Setup
+
+Set your OpenAI API key:
+
+```bash
+export OPENAI_API_KEY="sk-..."
+```
+
+### Usage
+
+```rust
+use memvid_core::api_embed::{OpenAIConfig, OpenAIEmbedder};
+use memvid_core::types::embedding::EmbeddingProvider;
+
+// Use default model (text-embedding-3-small)
+let config = OpenAIConfig::default();
+let embedder = OpenAIEmbedder::new(config)?;
+
+let embedding = embedder.embed_text("hello world")?;
+assert_eq!(embedding.len(), 1536);
+
+// Use higher quality model
+let config = OpenAIConfig::large();  // text-embedding-3-large (3072 dims)
+let embedder = OpenAIEmbedder::new(config)?;
+```
+
+### Available Models
+
+| Model                    | Dimensions | Best For                   |
+| ------------------------ | ---------- | -------------------------- |
+| `text-embedding-3-small` | 1536       | Default, fastest, cheapest |
+| `text-embedding-3-large` | 3072       | Highest quality            |
+| `text-embedding-ada-002` | 1536       | Legacy model               |
+
+See `examples/openai_embedding.rs` for a complete example.
+
+
+
+## File Format

-
-```python
-from memvid import MemvidEncoder
-
-# Create encoder
-encoder = MemvidEncoder()
-
-# Add individual chunks
-chunks = [
-    "Quantum computers use qubits instead of classical bits",

-]
-encoder.add_chunks(chunks)
-
-# Or add text with automatic chunking
-long_text = """Your long document text here..."""
-encoder.add_text(long_text, chunk_size=200, overlap=50)
-
-# Build video and index
-encoder.build_video("output/knowledge.mp4", "output/knowledge_index.json")
-```
-
-### 2. Searching the Memory
-
-```python

-chat.start_session()
-
-# Have a conversation
-response = chat.chat("What do you know about quantum computers?")
-print(response)
-```
-
-## Architecture
-
-### Data Flow Pipeline
-
-```
-1. Text Input → Chunking → Embeddings → QR Codes → Video Frames → MP4 File
-                    ↓
-                Vector Index → FAISS Index → JSON Metadata
-
-2. Query → Embedding → Vector Search → Frame Numbers → QR Decode → Text
-                             ↓
-                     Retrieved Context → LLM → Response

-
-## File Outputs Explained
-
-When you build a memory video, two files are created:
-
-### 1. MP4 Video File (`memory.mp4`)
-
-**What it is:** A video file where each frame is a QR code containing encoded text data.
-
-**Structure:**
-- Each frame = 1 QR code
-- Each QR code = 1 text chunk + metadata
-- Frame rate = 30 FPS (configurable)
-- Resolution = 512x512 pixels (configurable)
-
-**Contents of each QR code:**
-```json
-{
-    "id": 0,
-    "text": "The actual text chunk content...",
-    "metadata": {
-        "source": "optional source info",
-        "timestamp": "2024-01-01T00:00:00"
-    }
-}
-```
-
-**Why video?**
-- Efficient compression (H.264/H.265)
-- Portable and shareable
-- Streamable over networks
-- Supported everywhere
-
-### 2. Index Files (`memory_index.json` + `memory_index.faiss`)
-
-**What they are:** Search index files for fast retrieval.
-
-**memory_index.json structure:**
-```json
-{
-    "metadata": [
-        {
-            "chunk_id": 0,
-            "text": "Text preview (first 200 chars)...",
-            "frame": 0,
-            "char_count": 250,
-            "word_count": 45
-        }
-    ],
-    "chunk_to_frame": {
-        "0": 0,
-        "1": 1
-    },
-    "frame_to_chunks": {
-        "0": [0],
-        "1": [1]
-    },
-    "config": {
-        "embedding": {
-            "model": "all-MiniLM-L6-v2",
-            "dimension": 384
-        },
-        "index": {
-            "type": "Flat"
-        }
-    }
-}
-```
-
-**memory_index.faiss:** Binary vector index for similarity search.
-
-### File Size Comparison
-
-For 10,000 text chunks (average 200 chars each):
-- Raw text: ~2 MB
-- MP4 video: ~15-20 MB (with compression)
-- FAISS index: ~15 MB (384-dim vectors)
-- JSON metadata: ~3 MB
-
-## Core Components
-
-### 1. MemvidEncoder
-
-Handles text processing and video creation.
-
-```python
-from memvid import MemvidEncoder
-
-encoder = MemvidEncoder(config={
-    "qr": {
-        "version": 10,          # QR code version (1-40)
-        "error_correction": "H", # Error correction level (L/M/Q/H)
-        "box_size": 10,         # Pixel size of QR boxes
-        "border": 4             # Border size
-    },
-    "video": {
-        "fps": 30,              # Frames per second
-        "codec": "libx264",     # Video codec
-        "crf": 23,              # Quality (lower = better)
-        "preset": "medium"      # Encoding speed
-    }
-})
-
-# Add data

-
-## Advanced Usage
-
-### Custom Chunking Strategies
-
-```python
-from memvid import MemvidEncoder
-import re
-
-def custom_chunker(text, max_size=200):
-    """Chunk by sentences, respecting max size"""
-    sentences = re.split(r'(?<=[.!?])\s+', text)
-    chunks = []
-    current = ""
-    
-    for sentence in sentences:
-        if len(current) + len(sentence) > max_size and current:
-            chunks.append(current.strip())
-            current = sentence
-        else:
-            current += " " + sentence
-    
-    if current:
-        chunks.append(current.strip())
-    
-    return chunks
-
-encoder = MemvidEncoder()
-chunks = custom_chunker(long_text)
-encoder.add_chunks(chunks)
-```
-
-### Metadata Enrichment
-
-```python
-encoder = MemvidEncoder()
-
-# Add chunks with metadata
-chunks_with_meta = [
-    {
-        "text": "Quantum computing breakthrough...",
-        "metadata": {
-            "source": "arxiv:2024.1234",
-            "date": "2024-01-15",
-            "category": "quantum",
-            "author": "Smith et al."
-        }
-    }
-]
-
-for item in chunks_with_meta:
-    encoder.add_chunk(item["text"], metadata=item["metadata"])
-```
-
-### Custom Embedding Models
-
-```python
-from sentence_transformers import SentenceTransformer
-
-# Use a different embedding model
-encoder = MemvidEncoder(config={
-    "embedding": {
-        "model": "all-mpnet-base-v2",  # Higher quality
-        "dimension": 768,
-        "batch_size": 32
-    }
-})
-```
-
-### Batch Processing Large Datasets
-
-```python
-import os
-from pathlib import Path
-
-def process_directory(dir_path, output_prefix):
-    """Process all text files in directory"""
-    encoder = MemvidEncoder()
-    
-    for file_path in Path(dir_path).glob("*.txt"):
-        with open(file_path, 'r') as f:
-            text = f.read()
-            encoder.add_text(
-                text, 
-                chunk_size=300,
-                overlap=50,
-                metadata={"source": file_path.name}
-            )
-    
-    # Build video
-    encoder.build_video(
-        f"{output_prefix}.mp4",
-        f"{output_prefix}_index.json"
-    )
-
-# Process all documents
-process_directory("documents/", "output/knowledge_base")
-```
-
-### Multi-Video Federation
-
-```python
-class MemvidFederation:
-    """Search across multiple video memories"""
-    
-    def __init__(self):
-        self.retrievers = {}
-    
-    def add_memory(self, name, video_file, index_file):
-        self.retrievers[name] = MemvidRetriever(video_file, index_file)
-    
-    def search_all(self, query, top_k=5):
-        all_results = []
-        
-        for name, retriever in self.retrievers.items():
-            results = retriever.search_with_metadata(query, top_k)
-            for r in results:
-                r['source'] = name
-                all_results.append(r)

-## Performance Optimization
-
-### 1. Encoding Performance
-
-```python
-# Parallel encoding for large datasets
-encoder = MemvidEncoder(config={
-    "encoding": {
-        "max_workers": 8,        # Parallel QR generation
-        "batch_size": 100        # Process in batches
-    },
-    "video": {
-        "preset": "ultrafast",   # Faster encoding
-        "crf": 28               # Lower quality = faster
-    }
-})
-```
-
-### 2. Retrieval Performance
-
-```python
-# Optimize for speed
-retriever = MemvidRetriever(video_file, index_file, config={
-    "retrieval": {
-        "cache_size": 5000,      # Larger cache
-        "batch_size": 100,       # Bigger batches
-        "max_workers": 8,        # More threads
-        "preload_frames": True   # Preload common frames
-    }
-})
-
-# Warm up cache with common queries
-common_queries = ["AI", "machine learning", "data"]
-for query in common_queries:
-    retriever.search(query, top_k=10)
-```
-
-### 3. Index Optimization
-
-```python
-# Use approximate search for large datasets
-encoder = MemvidEncoder(config={
-    "index": {
-        "type": "IVF",          # Inverted file index
-        "nlist": 100,           # Number of clusters
-        "nprobe": 10           # Clusters to search
-    }
-})
-
-# Or use HNSW for better quality
-encoder = MemvidEncoder(config={
-    "index": {
-        "type": "HNSW",         # Hierarchical NSW
-        "M": 32,                # Number of connections
-        "ef_construction": 200  # Construction parameter
-    }
-})
-```
-
-### 4. Memory Management
-
-```python
-# For very large videos
-retriever = MemvidRetriever(video_file, index_file, config={
-    "retrieval": {
-        "mmap_video": True,      # Memory-map video file
-        "chunk_buffer": 1000,    # Buffer size
-        "gc_interval": 100       # Garbage collection
-    }
-})
-```
-
-## Troubleshooting
-
-### Common Issues
-
-#### 1. "huggingface/tokenizers" Warning
-```bash
-# Set before running
-export TOKENIZERS_PARALLELISM=false
-
-# Or in Python
-import os
-os.environ['TOKENIZERS_PARALLELISM'] = 'false'
-```
-
-#### 2. QR Decode Failures
-```python
-# Increase QR code quality
-encoder = MemvidEncoder(config={
-    "qr": {
-        "error_correction": "H",  # Highest correction
-        "version": 15,           # Larger QR codes
-        "box_size": 15          # Bigger pixels
-    }
-})
-```
-
-#### 3. Video Codec Issues
-```python
-# Try different codecs
-encoder = MemvidEncoder(config={
-    "video": {
-        "codec": "libx265",     # Or "h264_nvenc" for NVIDIA
-        "pixel_format": "yuv420p"
-    }
-})
-```
-
-#### 4. Memory Issues with Large Videos
-```python
-# Enable streaming mode
-retriever = MemvidRetriever(video_file, index_file, config={
-    "retrieval": {
-        "streaming_mode": True,
-        "buffer_size": 100      # Frames in memory
-    }
-})
-```
-
-#### 5. Slow Search Performance
-```python
-# Debug performance
-stats = retriever.get_stats()
-print(f"Average decode time: {stats['avg_decode_time']}ms")
-print(f"Cache hit rate: {stats['cache_hit_rate']:.2%}")
-
-# Enable profiling
-retriever.enable_profiling()
-results = retriever.search("test query")
-print(retriever.get_profile_stats())
-```
-
-### Debugging Tips
-
-```python
-# Enable detailed logging
-import logging
-logging.basicConfig(level=logging.DEBUG)
-
-# Check video integrity
-from memvid.utils import verify_video
-is_valid, stats = verify_video("output.mp4")
-print(f"Valid: {is_valid}")
-print(f"Readable frames: {stats['readable_frames']}/{stats['total_frames']}")
-
-# Test QR encoding/decoding
-from memvid.utils import create_qr_code, decode_qr
-qr_img = create_qr_code("test data")
-decoded = decode_qr(qr_img)
-assert decoded == "test data"
-```
-
-## Best Practices
-
-1. **Chunk Size**: 100-500 characters works best
-2. **Overlap**: 20-30% overlap prevents context loss
-3. **Video FPS**: 30 FPS is optimal (higher = larger files)
-4. **Cache Size**: Set to 10% of total frames
-5. **Batch Size**: 50-100 for parallel processing
-6. **Error Correction**: Use "H" for archival, "L" for speed
-
-## Example Projects
-
-### 1. Personal Knowledge Base
-```python
-# Build from markdown files
-from pathlib import Path
-
-encoder = MemvidEncoder()
-for md_file in Path("notes/").glob("**/*.md"):
-    with open(md_file) as f:
-        encoder.add_text(f.read(), metadata={"file": str(md_file)})
-
-encoder.build_video("personal_kb.mp4", "personal_kb_index.json")
-```
-
-### 2. Documentation Search
-```python
-# Create searchable docs
-encoder = MemvidEncoder()
-encoder.add_text(api_docs, metadata={"type": "api"})
-encoder.add_text(tutorials, metadata={"type": "tutorial"})
-encoder.build_video("docs.mp4", "docs_index.json")
-
-# Search with filtering
-retriever = MemvidRetriever("docs.mp4", "docs_index.json")
-api_results = [r for r in retriever.search_with_metadata("authentication") 
-               if r.get("metadata", {}).get("type") == "api"]
-```
-
-### 3. Research Paper Archive
-```python
-# Archive papers with citations
-papers = load_papers()  # Your paper loader
-encoder = MemvidEncoder()
-
-for paper in papers:
-    encoder.add_text(
-        paper["abstract"],
-        metadata={
-            "title": paper["title"],
-            "authors": paper["authors"],
-            "year": paper["year"],
-            "doi": paper["doi"]
-        }
-    )
-
-encoder.build_video("papers.mp4", "papers_index.json")
-```

+//!
+//! # Benchmarks
+//!
+//! - `query_two_words`: Measures latency for simple two-word queries
+//! - `precision_calculation`: Measures precision metrics and filtering overhead
+//! - `result_count`: Measures result set size impact

+# Docker Images for Memvid
+
+This directory contains Docker configurations for Memvid components.
+
+## Available Images
+
+### Memvid Core (`core/`)
+
+The Memvid Core Docker images provide containerized Rust development, testing, and build environments for the `memvid-core` library.
+
+**Quick Start:**
+```bash
+# Development environment
+cd core
+docker-compose up -d dev
+docker-compose exec dev bash
+
+# Run tests
+docker-compose run --rm test
+
+# Build release
+docker-compose run --rm build
+```
+
+For detailed usage, see [core/README.md](core/README.md).
+
+### Memvid CLI (`cli/`)
+
+The Memvid CLI Docker image provides a containerized version of the `memvid-cli` tool, allowing you to run Memvid commands without installing Node.js or dealing with platform-specific binaries.
+
+**Quick Start:**
+
+```bash
+# Pull the image
+docker pull memvid/cli
+
+# Create a memory
+docker run --rm -v $(pwd):/data memvid/cli create my-memory.mv2
+
+# Add documents
+docker run --rm -v $(pwd):/data memvid/cli put my-memory.mv2 --input doc.pdf
+
+# Search
+docker run --rm -v $(pwd):/data memvid/cli find my-memory.mv2 --query "search"
+```
+
+For detailed usage instructions, examples, and Docker Compose configurations, see [cli/README.md](cli/README.md).
+
+## Building Images
+
+### Build CLI Image Locally
+
+```bash
+cd cli
+docker build -t memvid/cli:test .
+```
+
+## Publishing
+
+Docker images are automatically built and published to Docker Hub via GitHub Actions when tags are pushed. See `.github/workflows/docker-release.yml` for the CI/CD configuration.
+
+**Image Registry:**
+- Docker Hub: `memvid/cli`
+- Tags: `latest`, `2.0.129`, and version-specific tags
+
+## Architecture Support
+
+The CLI image supports multi-architecture builds:
+- `linux/amd64`
+- `linux/arm64`
+
+## Security
+
+The CLI image runs as a non-root user (`memvid`) for improved security. When mounting volumes, ensure your host directories have appropriate permissions.

-# WSL + Docker Desktop Troubleshooting Guide
-
-## Quick Setup Check
-
-```bash
-# Run this to check your setup
-make setup-wsl
-make wsl-info
-```
-
-## Common Issues & Solutions
-
-### 1. "Docker not found" in WSL
-
-**Problem**: `docker: command not found` or `make build` fails
-
-**Solutions**:
-1. **Enable WSL Integration in Docker Desktop**:
-    - Open Docker Desktop on Windows
-    - Go to Settings → Resources → WSL Integration
-    - Enable "Enable integration with my default WSL distro"
-    - Enable integration with your specific distro (Ubuntu, etc.)
-    - Click "Apply & Restart"
-
-2. **Restart WSL** (in Windows Command Prompt):
-   ```cmd
-   wsl --shutdown
-   wsl
-   ```
-
-3. **Check Docker Desktop is running**:
-    - Look for Docker whale icon in Windows system tray
-    - Should show "Docker Desktop is running"
-
-### 2. Performance Issues
-
-**Problem**: Encoding is very slow in WSL
-
-**Solutions**:
-
-1. **Use WSL 2** (much faster than WSL 1):
-   ```cmd
-   # In Windows Command Prompt
-   wsl --set-default-version 2
-   wsl --set-version Ubuntu 2  # or your distro name
-   ```
-
-2. **Store files in WSL filesystem**:
-   ```bash
-   # Good: /home/user/projects/memvid
-   # Bad:  /mnt/c/Users/user/projects/memvid
-   
-   # Move your project if needed:
-   cp -r /mnt/c/path/to/memvid ~/memvid
-   cd ~/memvid
-   ```
-
-3. **Configure WSL memory** (create `C:\Users\YourName\.wslconfig`):
-   ```ini
-   [wsl2]
-   memory=8GB
-   processors=4
-   swap=2GB
-   ```
-
-### 3. Volume Mount Issues
-
-**Problem**: Container can't see files in `data/` directory
-
-**Solutions**:
-
-1. **Check file permissions**:
-   ```bash
-   ls -la data/
-   chmod 755 data/
-   chmod 644 data/input/*
-   ```
-
-2. **Use absolute paths**:
-   ```bash
-   # The Makefile handles this, but if running docker directly:
-   docker run -v "$(pwd)/data:/compute" memvid-h265 encode input.json output.mp4
-   ```
-
-3. **Verify mount is working**:
-   ```bash
-   docker run --rm -v "$(pwd)/data:/compute" memvid-h265 ls -la /compute
-   ```
-
-### 4. Memory Issues
-
-**Problem**: "Out of memory" or very slow encoding
-
-**Solutions**:
-
-1. **Check available memory**:
-   ```bash
-   free -h
-   make wsl-info
-   ```
-
-2. **Use smaller batch sizes** for large datasets:
-   ```bash
-   # Edit the encoding script or split your data
-   split -l 1000 large_chunks.json chunk_
-   ```
-
-3. **Increase WSL memory allocation** (see #2 above)
-
-### 5. Path Issues
-
-**Problem**: Windows/Linux path confusion
-
-**Solutions**:
-
-1. **Always use forward slashes** in WSL:
-   ```bash
-   # Good
-   /home/user/memvid/data/input/file.json
-   
-   # Bad  
-   C:\Users\user\memvid\data\input\file.json
-   ```
-
-2. **Use WSL paths for Docker volumes**:
-   ```bash
-   # Good: Let the Makefile handle paths
-   make encode INPUT=file.json OUTPUT=video.mp4
-   
-   # Or use $(pwd) which resolves correctly
-   docker run -v "$(pwd)/data:/compute" memvid-h265 encode file.json video.mp4
-   ```
-
-## Performance Optimization
-
-### For Large Datasets
-
-1. **Use the optimized command**:
-   ```bash
-   make encode-large INPUT=big_file.json OUTPUT=big_video.mp4
-   ```
-
-2. **Monitor resources**:
-   ```bash
-   # In another terminal
-   htop
-   # or
-   docker stats
-   ```
-
-3. **Use SSD storage** if possible for temp files
-
-### WSL 2 vs WSL 1
-
-| Feature | WSL 1 | WSL 2 |
-|---------|-------|-------|
-| Docker performance | Slow | Fast |
-| File system | Windows FS | Linux FS |
-| Memory usage | Shared | Allocated |
-| **Recommendation** | Upgrade to WSL 2 | ✅ Use this |
-
-## Testing Your Setup
-
-Run this complete test:
-
-```bash
-# 1. Check environment
-make setup-wsl
-
-# 2. Check performance info
-make wsl-info
-
-# 3. Run the getting started example
-./examples/getting_started.sh
-
-# 4. Test with larger dataset
-echo '["test chunk '$i'" for i in {1..100}]' | jq -c . > data/input/test_100.json
-make encode INPUT=test_100.json OUTPUT=test_100.mp4
-```
-
-## Getting Help
-
-If you're still having issues:
-
-1. **Check Docker Desktop logs**:
-    - Open Docker Desktop → Troubleshoot → View logs
-
-2. **Check WSL logs**:
-   ```bash
-   dmesg | tail -20
-   ```
-
-3. **Verify versions**:
-   ```bash
-   wsl --version
-   docker --version
-   make setup-wsl
-   ```
-
-4. **Test basic Docker functionality**:
-   ```bash
-   docker run --rm hello-world
-   docker run --rm -v "$(pwd):/test" ubuntu:22.04 ls -la /test
-   ```
-
-## Pro Tips
-
-1. **Use Windows Terminal** for better WSL experience
-2. **Install Docker Desktop with WSL 2 backend**
-3. **Keep projects in WSL filesystem** (`/home/user/...`)
-4. **Use VSCode with WSL extension** for seamless development
-5. **Monitor Windows Task Manager** to see Docker Desktop resource usage

+# Docker Setup for Memvid Core
+
+This document describes how to use Docker with the Memvid Core Rust library.
+
+## Quick Start
+
+### Development Environment
+
+```bash
+# From project root or docker/core directory
+cd docker/core
+docker-compose up -d dev
+
+# Enter the container
+docker-compose exec dev bash
+
+# Inside container, you can run:
+cargo build
+cargo test
+cargo run --example basic_usage
+```
+
+### Run Tests
+
+```bash
+# Run all tests
+cd docker/core
+docker-compose run --rm test
+
+# Or build test image manually (from project root)
+docker build -f docker/core/Dockerfile.test -t memvid-test .
+docker run --rm memvid-test
+```
+
+### Build Release
+
+```bash
+# Build release version
+cd docker/core
+docker-compose run --rm build
+
+# Or build manually (from project root)
+docker build -f docker/core/Dockerfile -t memvid-core:latest .
+```
+
+## Docker Images
+
+### 1. Development Image (`Dockerfile.dev`)
+
+Full development environment with all tools:
+
+```bash
+# From project root
+docker build -f docker/core/Dockerfile.dev -t memvid-dev .
+docker run -it --rm -v $(pwd):/app memvid-dev bash
+```
+
+**Features:**
+- Rust toolchain 1.92
+- All build dependencies
+- Cargo watch (optional)
+- Volume mounting for live development
+
+### 2. Test Image (`Dockerfile.test`)
+
+Optimized for running tests:
+
+```bash
+# From project root
+docker build -f docker/core/Dockerfile.test -t memvid-test .
+docker run --rm memvid-test
+```
+
+**Features:**
+- Rust toolchain 1.92
+- Test dependencies
+- Runs tests automatically
+
+### 3. Production Build (`Dockerfile`)
+
+Multi-stage build for optimized production image:
+
+```bash
+# From project root
+docker build -f docker/core/Dockerfile -t memvid-core:latest .
+```
+
+**Features:**
+- Multi-stage build (smaller final image)
+- Only runtime dependencies
+- Optimized release build
+
+## Docker Compose
+
+### Services
+
+- **`dev`** - Development environment with live code mounting
+- **`test`** - Test runner
+- **`build`** - Release builder
+
+### Usage
+
+```bash
+# Start development environment
+docker-compose up -d dev
+
+# Run tests
+docker-compose run --rm test
+
+# Build release
+docker-compose run --rm build
+
+# Stop all services
+docker-compose down
+```
+
+## Examples
+
+### Run Examples in Docker
+
+```bash
+# Development container
+docker-compose exec dev cargo run --example basic_usage
+
+# With features
+docker-compose exec dev cargo run --example pdf_ingestion --features lex,pdf_extract
+```
+
+### Memory-Constrained Testing
+
+Test OOM prevention with memory limits:
+
+```bash
+# Test with memory limit (for OOM testing)
+docker run --rm --memory=150m --memory-swap=150m \
+  -v $(pwd):/app \
+  memvid-test cargo test --features encryption --test encryption_capsule
+```
+
+### Build with Specific Features
+
+```bash
+# Build with all features
+docker-compose exec dev cargo build --release --all-features
+
+# Build with specific features
+docker-compose exec dev cargo build --release --features lex,vec,encryption
+```
+
+## Volume Mounts
+
+The docker-compose setup uses volumes for:
+- **Source code** - Live mounting for development
+- **Cargo cache** - Speeds up builds
+- **Target cache** - Preserves build artifacts
+
+## CI/CD Integration
+
+### GitHub Actions Example
+
+```yaml
+name: Docker Build
+
+on: [push, pull_request]
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - name: Build Docker image
+        run: docker build -t memvid-core:test .
+      - name: Run tests
+        run: docker run --rm memvid-core:test cargo test
+```
+
+## Troubleshooting
+
+### Build Fails
+
+```bash
+# Clean build
+docker-compose down -v
+docker-compose build --no-cache
+```
+
+### Permission Issues
+
+```bash
+# Fix permissions
+sudo chown -R $USER:$USER .
+```
+
+### Out of Memory
+
+```bash
+# Increase Docker memory limit in Docker Desktop settings
+# Or use memory limits in docker run:
+docker run --memory=2g --memory-swap=2g ...
+```
+
+## Best Practices
+
+1. **Use docker-compose** for development
+2. **Cache volumes** for faster builds
+3. **Multi-stage builds** for production
+4. **Test in containers** to match CI/CD environment
+5. **Use .dockerignore** to exclude unnecessary files

+# Docker Setup for Memvid Core
+
+This document describes how to use Docker with the Memvid Core Rust library.
+
+## Quick Start
+
+### Development Environment
+
+```bash
+# From project root or docker/core directory
+cd docker/core
+docker-compose up -d dev
+
+# Enter the container
+docker-compose exec dev bash
+
+# Inside container, you can run:
+cargo build
+cargo test
+cargo run --example basic_usage
+```
+
+### Run Tests
+
+```bash
+# Run all tests
+cd docker/core
+docker-compose run --rm test
+
+# Or build test image manually (from project root)
+docker build -f docker/core/Dockerfile.test -t memvid-test .
+docker run --rm memvid-test
+```
+
+### Build Release
+
+```bash
+# Build release version
+cd docker/core
+docker-compose run --rm build
+
+# Or build manually (from project root)
+docker build -f docker/core/Dockerfile -t memvid-core:latest .
+```
+
+## Docker Images
+
+### 1. Development Image (`Dockerfile.dev`)
+
+Full development environment with all tools:
+
+```bash
+# From project root
+docker build -f docker/core/Dockerfile.dev -t memvid-dev .
+docker run -it --rm -v $(pwd):/app memvid-dev bash
+```
+
+**Features:**
+- Rust toolchain 1.92
+- All build dependencies
+- Cargo watch (optional)
+- Volume mounting for live development
+
+### 2. Test Image (`Dockerfile.test`)
+
+Optimized for running tests:
+
+```bash
+# From project root
+docker build -f docker/core/Dockerfile.test -t memvid-test .
+docker run --rm memvid-test
+```
+
+**Features:**
+- Rust toolchain 1.92
+- Test dependencies
+- Runs tests automatically
+
+### 3. Production Build (`Dockerfile`)
+
+Multi-stage build for optimized production image:
+
+```bash
+# From project root
+docker build -f docker/core/Dockerfile -t memvid-core:latest .
+```
+
+**Features:**
+- Multi-stage build (smaller final image)
+- Only runtime dependencies
+- Optimized release build
+
+## Docker Compose
+
+### Services
+
+- **`dev`** - Development environment with live code mounting
+- **`test`** - Test runner
+- **`build`** - Release builder
+
+### Usage
+
+```bash
+# Start development environment
+docker-compose up -d dev
+
+# Run tests
+docker-compose run --rm test
+
+# Build release
+docker-compose run --rm build
+
+# Stop all services
+docker-compose down
+```
+
+## Examples
+
+### Run Examples in Docker
+
+```bash
+# Development container
+docker-compose exec dev cargo run --example basic_usage
+
+# With features
+docker-compose exec dev cargo run --example pdf_ingestion --features lex,pdf_extract
+```
+
+### Memory-Constrained Testing
+
+Test OOM prevention with memory limits:
+
+```bash
+# Test with memory limit (for OOM testing)
+docker run --rm --memory=150m --memory-swap=150m \
+  -v $(pwd):/app \
+  memvid-test cargo test --features encryption --test encryption_capsule
+```
+
+### Build with Specific Features
+
+```bash
+# Build with all features
+docker-compose exec dev cargo build --release --all-features
+
+# Build with specific features
+docker-compose exec dev cargo build --release --features lex,vec,encryption
+```
+
+## Volume Mounts
+
+The docker-compose setup uses volumes for:
+- **Source code** - Live mounting for development
+- **Cargo cache** - Speeds up builds
+- **Target cache** - Preserves build artifacts
+
+## CI/CD Integration
+
+### GitHub Actions Example
+
+```yaml
+name: Docker Build
+
+on: [push, pull_request]
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - name: Build Docker image
+        run: docker build -t memvid-core:test .
+      - name: Run tests
+        run: docker run --rm memvid-core:test cargo test
+```
+
+## Troubleshooting
+
+### Build Fails
+
+```bash
+# Clean build
+docker-compose down -v
+docker-compose build --no-cache
+```
+
+### Permission Issues
+
+```bash
+# Fix permissions
+sudo chown -R $USER:$USER .
+```
+
+### Out of Memory
+
+```bash
+# Increase Docker memory limit in Docker Desktop settings
+# Or use memory limits in docker run:
+docker run --memory=2g --memory-swap=2g ...
+```
+
+## Best Practices
+
+1. **Use docker-compose** for development
+2. **Cache volumes** for faster builds
+3. **Multi-stage builds** for production
+4. **Test in containers** to match CI/CD environment
+5. **Use .dockerignore** to exclude unnecessary files

+# Contributing Translations (i18n)
+
+Thank you for helping translate Memvid’s documentation and make the project accessible to a global audience.
+
+This guide explains how to contribute translations for the main `README.md`.
+
+---
+
+## What Can Be Translated
+
+- The main repository `README.md`
+- Translations are stored in `docs/i18n/`
+- Each language has a single translation file
+
+---
+
+## Translation Workflow
+
+### 1. Check Existing Issues
+
+Before starting:
+- Check open issues to see if your language is already in progress
+- If an issue exists, comment on it to indicate you want to work on it
+- Only one contributor should work on a language at a time
+
+---
+
+### 2. Create a Translation Issue (If Needed)
+
+If no issue exists for your language, open a new one using this format:
+
+**Title:**
+```
+README translation: <Language> (<code>)
+```
+
+**Labels to apply:**
+- `i18n`
+- `documentation`
+- `help wanted` or `good first issue`
+
+---
+
+### 3. Create the Translation File
+
+1. Copy the main `README.md` from the repository root
+2. Create a new file in `docs/i18n/` using this format:
+
+   ```
+   README.<language-code>.md
+   ```
+
+   **Examples:**
+- `README.es.md`
+- `README.zh-CN.md`
+- `README.pt-BR.md`
+
+Use standard ISO language codes (include region where applicable).
+
+---
+
+## Translation Guidelines
+
+- **Preserve structure**  
+  Keep headings, section order, and formatting identical to the original README
+
+- **Preserve links and badges**  
+  Do not modify URLs, badges, or shields
+
+- **Preserve code blocks**  
+  Keep code examples, commands, flags, and API names in English
+
+- **Maintain technical accuracy**  
+  Translate naturally, but do not change meaning or behavior
+
+- **Language quality matters**  
+  Native or fluent speakers are strongly preferred
+
+---
+
+## Submitting Your Translation
+
+1. **Create a new branch:**
+   ```bash
+   git checkout -b docs/i18n-<language-code>
+   ```
+
+2. **Add your translation file** under `docs/i18n/`
+
+3. **Commit your changes:**
+   ```bash
+   git commit -m "docs(i18n): add <Language> README translation"
+   ```
+
+4. **Push to your fork** and open a Pull Request
+
+5. **Reference the translation issue** in your PR description
+
+---
+
+## Review Process
+
+- Maintainers may request:
+  - Clarifications
+  - Formatting fixes
+  - Review by another native speaker
+- Once approved, the PR will be merged
+- The corresponding issue will be closed
+
+---
+
+## Keeping Translations Up to Date
+
+When the main `README.md` changes significantly:
+
+- Existing translations may need updates
+- Contributors are encouraged to help keep translations in sync
+
+---
+
+## Getting Help
+
+- Open an issue if you have questions about translations
+- Use GitHub Discussions for coordination
+- Contact: [contact@memvid.com](mailto:contact@memvid.com)

+# المساهمة في Memvid (الترجمة العربية)
+
+<p align="center">
+<strong>Memvid هي طبقة ذاكرة مكونة من ملف واحد لوكلاء الذكاء الاصطناعي (AI Agents)، توفر استرجاعاً فورياً وذاكرة طويلة المدى.</strong>
+
+ذاكرة دائمة، مؤرشفة، وقابلة للنقل، دون الحاجة إلى قواعد بيانات.
+
+</p>
+
+<h2 align="center">⭐️ اترك نجمة (STAR) لدعم المشروع ⭐️</h2>
+
+---
+
+## ما هو Memvid؟
+
+Memvid هو نظام ذاكرة محمول للذكاء الاصطناعي يقوم بتغليف بياناتك، والمتجهات (Embeddings)، وهيكل البحث، والبيانات الوصفية في **ملف واحد فقط**.
+
+بدلاً من تشغيل خطوط أنابيب RAG معقدة أو قواعد بيانات متجهة تعتمد على الخادم، يتيح Memvid استرجاعاً سريعاً للبيانات مباشرة من الملف.
+
+النتيجة هي طبقة ذاكرة مستقلة عن النموذج (Model-agnostic) ولا تحتاج إلى بنية تحتية، مما يمنح وكلاء الذكاء الاصطناعي ذاكرة دائمة وطويلة المدى يمكنهم حملها في أي مكان.
+
+---
+
+## لماذا "إطارات الفيديو" (Video Frames)؟
+
+يستلهم Memvid فكرته من ترميز الفيديو، ليس لتخزين الفيديو، بل **لتنظيم ذاكرة الذكاء الاصطناعي كمتسلسلة فائقة الكفاءة من "الإطارات الذكية" (Smart Frames) التي تُضاف باستمرار.**
+
+"الإطار الذكي" هو وحدة غير قابلة للتغيير تخزن المحتوى مع الطوابع الزمنية، والتحقق من البيانات (Checksums)، والبيانات الوصفية الأساسية. يتم تجميع هذه الإطارات بطريقة تسمح بضغط البيانات وفهرستها والقراءة المتوازية بكفاءة عالية.
+
+يسمح هذا التصميم بـ:
+
+-   **إضافة البيانات فقط:** الكتابة دون تعديل أو إفساد البيانات الموجودة.
+-   **الاستعلام عبر الزمن:** البحث في حالات الذاكرة السابقة.
+-   **جدول زمني للمعرفة:** فحص كيفية تطور المعرفة بمرور الوقت.
+-   **سلامة البيانات:** ضمان عدم فقدان البيانات عند التعطل بفضل الإطارات الثابتة.
+
+---
+
+## المفاهيم الأساسية
+
+-   **محرك الذاكرة الحية:** إضافة وتطوير الذاكرة باستمرار عبر الجلسات.
+-   **كبسولة السياق (`.mv2`):** كبسولات ذاكرة ذاتية الاحتواء وقابلة للمشاركة مع قواعد وصلاحية محددة.
+-   **تصحيح السفر عبر الزمن:** إرجاع أو إعادة تشغيل أو تفريع أي حالة من حالات الذاكرة.
+-   **الاستدعاء الذكي:** وصول محلي للذاكرة في أقل من 5 ملي ثانية مع ذاكرة تخزين مؤقت تنبؤية.
+-   **ذكاء الترميز:** يختار ويحدث تقنيات الضغط تلقائياً بمرور الوقت.
+
+---
+
+## حالات الاستخدام
+
+نظرًا لأن Memvid يعمل دون اتصال بالإنترنت ومستقل عن النماذج، فإنه يُستخدم في:
+
+-   وكلاء الذكاء الاصطناعي طويلي الأمد.
+-   قواعد المعرفة للمؤسسات.
+-   أنظمة الذكاء الاصطناعي التي تعمل "بدون إنترنت أولاً".
+-   فهم الأكواد البرمجية (Codebases).
+-   المساعدين الشخصيين والأنظمة الطبية والقانونية والمالية.
+
+---
+
+## أدوات المطورين (SDKs)
+
+| الحزمة                        | طريقة التثبيت               |
+| ----------------------------- | --------------------------- |
+| **واجهة السطر البرمجي (CLI)** | `npm install -g memvid-cli` |
+| **Node.js SDK**               | `npm install @memvid/sdk`   |
+| **Python SDK**                | `pip install memvid-sdk`    |
+| **Rust**                      | `cargo add memvid-core`     |
+
+---
+
+## هيكل الملف
+
+كل شيء يعيش داخل ملف واحد بصيغة `.mv2`:
+
+```

+## মেমভিড কী?
+
+মেমভিড হল একটি পোর্টেবল এআই মেমরি সিস্টেম যা আপনার ডেটা, এম্বেডিং, অনুসন্ধান কাঠামো এবং মেটাডেটা একটি একক ফাইলে প্যাক করে।
+
+জটিল RAG পাইপলাইন বা সার্ভার-ভিত্তিক ভেক্টর ডাটাবেস চালানোর পরিবর্তে, Memvid ফাইল থেকে সরাসরি দ্রুত ডেটা পুনরুদ্ধারে সহায়তা করে।
+
+ফলাফল হল একটি মডেল-অজ্ঞেয়বাদী, অবকাঠামো-মুক্ত মেমোরি স্তর যা AI এজেন্টদের স্থায়ী, দীর্ঘমেয়াদী মেমোরি দেয় যা তারা যেকোনো জায়গায় নিতে পারে।
+---
+
+## ভিডিও ফ্রেম কেন?
+
+মেমভিড ভিডিও এনকোডিং থেকে অনুপ্রেরণা নেয়, ভিডিও সংরক্ষণের জন্য নয়, বরং এআই মেমোরিকে অ্যাপেন্ড-ওনলি, স্মার্ট ফ্রেমের অতি-দক্ষ সিকোয়েন্স হিসেবে সংগঠিত করার জন্য।
+
+একটি স্মার্ট ফ্রেম হল একটি অ-পরিবর্তনযোগ্য ইউনিট যা টাইমস্ট্যাম্প, চেকসাম এবং মৌলিক মেটাডেটা সহ বিষয়বস্তু সংরক্ষণ করে।
+ফ্রেমগুলিকে এমনভাবে গোষ্ঠীভুক্ত করা হয় যা দক্ষ কম্প্রেশন, ইনডেক্সিং এবং সমান্তরাল পঠনের সুযোগ করে দেয়।
+
+এই ফ্রেম-ভিত্তিক নকশাটি সক্ষম করে:
+
+- বিদ্যমান ডেটা পরিবর্তন বা দূষিত না করে কেবল ডেটা যোগ করা
+- পূর্ববর্তী মেমরি অবস্থা অনুসন্ধান করা
+- জ্ঞান কীভাবে বিকশিত হয় তার টাইমলাইন-স্টাইল তদন্ত
+- প্রতিশ্রুতিবদ্ধ, অপরিবর্তনীয় ফ্রেমের মাধ্যমে ক্র্যাশ সুরক্ষা
+- ভিডিও এনকোডিং থেকে গৃহীত কৌশল ব্যবহার করে দক্ষ কম্প্রেশন।
+
+ফলাফল হল একটি একক ফাইল যা AI সিস্টেমের জন্য একটি রিওয়াইন্ডেবল মেমরি টাইমলাইন হিসাবে কাজ করে।
+
+---
+
+## মূল ধারণা
+
+- **লিভিং মেমোরি ইঞ্জিন**
+
+একটি সেশনের সময় স্থায়ী মেমোরি যোগ করুন, শাখা করুন এবং বিকশিত করুন।
+
+- **ক্যাপসুল রেফারেন্স (`.mv2`)**
+
+নিয়ম এবং মেয়াদোত্তীর্ণতা সহ স্বয়ংসম্পূর্ণ, শেয়ারযোগ্য মেমোরি ক্যাপসুল।
+
+- **টাইম-ট্রাভেল ডিবাগিং**
+
+যেকোন মেমোরি স্টেট রিওয়াইন্ড, রিপ্লে বা শাখা করুন।
+
+- **স্মার্ট রিকল**
+
+প্রেডিক্টিভ ক্যাশিং সহ সাব-5ms স্থানীয় মেমোরি অ্যাক্সেস।
+
+- **কোডেক ইন্টেলিজেন্স**
+
+সময়ের সাথে সাথে স্বয়ংক্রিয়ভাবে কম্প্রেশন নির্বাচন এবং আপগ্রেড করে।
+

+
+## ব্যবহারের ক্ষেত্রে
+
+মেমভিড হল একটি পোর্টেবল, সার্ভারলেস মেমরি স্তর যা এআই এজেন্টদের স্থায়ী মেমরি এবং দ্রুত রিকল দেয়। যেহেতু এটি মডেল-অ্যাগনস্টিক, মাল্টি-মডেল এবং সম্পূর্ণ অফলাইনে কাজ করে, তাই ডেভেলপাররা বিভিন্ন বাস্তব-বিশ্ব অ্যাপ্লিকেশনে মেমভিড ব্যবহার করছে।
+
+- দীর্ঘমেয়াদী এআই এজেন্ট
+- এন্টারপ্রাইজ জ্ঞান ভিত্তি
+- অফলাইন-প্রথম এআই সিস্টেম
+- কোডবেস বোঝা
+- গ্রাহক সহায়তা এজেন্ট

+  <strong>Memvid je jednosouborová paměťová vrstva pro AI agenty s okamžitým vyhledáváním a dlouhodobou pamětí.</strong><br/>
+  Trvalá, verzovaná a přenosná paměť, bez databází.
+</p>
+
+<h2 align="center">⭐️ Zanechte hvězdičku na podporu projektu ⭐️</h2>
+</p>
+
+## Co je Memvid?
+
+Memvid je systém pro tvorbu AI pamětí, který balí vaše data, embeddingy, strukturu vyhledávání a metadata do jediného souboru.
+
+Místo spouštění složitých RAG řešení nebo serverových vektorových databází umožňuje Memvid rychlé vyhledávání přímo ze souboru.
+
+Výsledkem je modelově nezávislá paměťová vrstva bez infrastruktury, která poskytuje agentům AI trvalou, dlouhodobou paměť, kterou lze přenášet kamkoli.
+
+---
+
+## Co jsou inteligentní rámce?
+
+Memvid čerpá inspiraci z enkódování videa, nikoli za účelem ukládání videa, ale za účelem **organizace paměti AI jako ultraefektivní sekvence inteligentních rámců, do kterých lze data  pouze přidávat.**
+
+Inteligentní rámec je neměnná jednotka, která ukládá obsah spolu s časovými značkami, kontrolními součty a základními metadaty.
+Rámce jsou seskupeny tak, aby umožňovaly efektivní kompresi, indexování a paralelní čtení.
+
+Tento design založený na rámcích umožňuje:
+
+-  Pouze zápisy bez úpravy nebo poškození existujících dat
+-  Dotazy na minulé stavy paměti
+-  Kontrolu vývoje znalostí ve stylu časové osy
+-  Bezpečnost proti selhání díky závazným, neměnným rámcům
+-  Efektivní kompresi pomocí technik převzatých z kódování videa
+
+Výsledkem je jediný soubor, který se chová jako časová osa paměti pro systémy AI, ve které lze snadno hledat.
+
+---
+
+## Základní koncepty
+
+-   **Living Memory Engine**
+    Kontinuální přidávání, rozvětvování a vývoj paměti, napříč relacemi.
+
+-   **Capsule Context (`.mv2`)**
+    Samostatné, sdílené paměťové kapsle s pravidly a dobou platnosti.
+
+-   **Time-Travel Debugging**
+    Převíjení, přehrávání nebo rozvětvování libovolného stavu paměti.
+
+-   **Smart Recall**
+    Přístup k lokální paměti za méně než 5 ms s prediktivním ukládáním do mezipaměti.
+
+-   **Codec Intelligence**
+    Automaticky vybírá a vylepšuje kompresi v průběhu času.
+
+---
+
+## Případy použití
+
+Memvid je přenosná paměťová vrstva bez serveru, která poskytuje agentům AI trvalou paměť a rychlé vyvolání. Protože je modelově nezávislá, multimodální a funguje zcela offline, vývojáři používají Memvid v široké škále reálných aplikací.
+
+- Dlouhodobě běžící AI agenti
+- Firemní znalostní báze
+- Offline-First AI systémy
+- Porozumění kódu
+- Agenti zákaznické podpory
+- Automatizace pracovních postupů
+- Asistenti prodeje a marketingu
+- Osobní znalostní asistenti
+- Lékařští, právní a finanční agenti
+- Auditovatelné a laditelné AI pracovní postupy
+- Vlastní aplikace

+  <strong>Memvid es una capa de memoria de un solo archivo para agentes de IA, con recuperación instantánea y memoria a largo plazo.</strong><br/>
+  Memoria persistente, versionada y portable, sin bases de datos.
+</p>
+
+<h2 align="center">⭐️ Deja una STAR para apoyar el proyecto ⭐️</h2>
+</p>
+

+
+**🧠 Mejor razonamiento multi-hop y temporal:** +76% en multi-hop y +56% en temporal frente al promedio de la industria.
+
+**⚡ Latencia ultra baja a escala:** 0.025 ms P50 y 0.075 ms P99, con 1,372× más throughput que los enfoques estándar.
+
+**🔬 Benchmarks totalmente reproducibles:** LoCoMo (10 conversaciones de ~26K tokens), evaluación open source y LLM-as-Judge.
+
+---
+
+## ¿Qué es Memvid?
+
+Memvid es un sistema de memoria portable para IA que empaqueta tus datos, embeddings, estructura de búsqueda y metadatos en un solo archivo.
+
+En lugar de ejecutar pipelines RAG complejos o bases de datos vectoriales basadas en servidor, Memvid permite una recuperación rápida directamente desde el archivo.
+
+El resultado es una capa de memoria agnóstica al modelo, sin infraestructura, que da a los agentes de IA una memoria persistente y a largo plazo que pueden llevar a cualquier parte.
+
+---
+
+## ¿Por qué fotogramas de vídeo?
+
+Memvid se inspira en la codificación de vídeo, no para almacenar vídeo, sino para **organizar la memoria de IA como una secuencia de Smart Frames ultrarrápida y append-only.**
+
+Un Smart Frame es una unidad inmutable que almacena contenido junto con marcas de tiempo (timestamps), checksums y metadatos básicos.
+Los frames se agrupan de una forma que permite una compresión, indexación y lecturas paralelas eficientes.
+
+Este diseño basado en frames permite:
+
+-   Escrituras append-only sin modificar ni corromper los datos existentes
+-   Consultas sobre estados pasados de la memoria
+-   Inspección estilo línea temporal (timeline) de cómo evoluciona el conocimiento
+-   Seguridad ante fallos (crash safety) mediante frames confirmados e inmutables
+-   Compresión eficiente usando técnicas adaptadas de la codificación de vídeo
+
+El resultado es un único archivo que se comporta como una línea temporal de memoria “rebobinable” para sistemas de IA.
+
+---
+
+## Conceptos principales
+
+-   **Living Memory Engine**
+    Añade, ramifica (branch) y evoluciona la memoria de forma continua entre sesiones.
+
+-   **Capsule Context (`.mv2`)**
+    Cápsulas de memoria autocontenidas y compartibles, con reglas y caducidad.
+
+-   **Time-Travel Debugging**
+    Rebobina, reproduce (replay) o ramifica cualquier estado de memoria.
+
+-   **Smart Recall**
+    Acceso local a memoria en menos de 5ms con caché predictiva.
+
+-   **Codec Intelligence**
+    Selecciona y actualiza la compresión automáticamente con el tiempo.
+
+---
+
+## Casos de uso
+
+Memvid es una capa de memoria portable y serverless que da a los agentes de IA memoria persistente y recuerdo rápido. Como es agnóstica al modelo, multi-modal y funciona totalmente offline, los desarrolladores están usando Memvid en una amplia gama de aplicaciones reales.
+
+-   Agentes de IA de larga duración
+-   Bases de conocimiento empresariales
+-   Sistemas de IA offline-first
+-   Comprensión de codebases
+-   Agentes de soporte al cliente
+-   Automatización de flujos de trabajo
+-   Copilotos de ventas y marketing
+-   Asistentes de conocimiento personal
+-   Agentes médicos, legales y financieros
+-   Flujos de trabajo de IA auditables y depurables
+-   Aplicaciones personalizadas

+curl -L 'https://huggingface.co/thenlper/gte-large/resolve/main/onnx/model.onnx' \
+  -o ~/.cache/memvid/text-models/gte-large.onnx
+curl -L 'https://huggingface.co/thenlper/gte-large/resolve/main/tokenizer.json' \
+  -o ~/.cache/memvid/text-models/gte-large_tokenizer.json
+```
+
+### Uso en código
+
+```rust
+use memvid_core::text_embed::{LocalTextEmbedder, TextEmbedConfig};
+use memvid_core::types::embedding::EmbeddingProvider;
+
+// Usar el modelo por defecto (BGE-small)
+let config = TextEmbedConfig::default();
+let embedder = LocalTextEmbedder::new(config)?;
+
+let embedding = embedder.embed_text("hello world")?;
+assert_eq!(embedding.len(), 384);
+
+// Usar un modelo distinto
+let config = TextEmbedConfig::bge_base();
+let embedder = LocalTextEmbedder::new(config)?;
+```
+
+Consulta `examples/text_embedding.rs` para ver un ejemplo completo con cálculo de similitud y ranking de búsqueda.
+
+### Consistencia del modelo
+
+Para evitar mezclar modelos por accidente, por ejemplo consultar un índice BGE-small con embeddings de OpenAI, puedes asociar explícitamente tu instancia de Memvid a un nombre de modelo:
+
+```rust
+// Vincula el índice a un modelo concreto.
+// Si el índice ya fue creado con otro modelo, devolverá un error.
+mem.set_vec_model("bge-small-en-v1.5")?;
+```
+
+Esta vinculación es persistente. Una vez definida, cualquier intento futuro de usar otro nombre de modelo fallará de inmediato con un error `ModelMismatch`.
+
+---
+
+## Embeddings por API (OpenAI)
+
+La feature `api_embed` habilita la generación de embeddings en la nube usando la API de OpenAI.
+
+### Configuración
+
+Define tu clave de API de OpenAI:
+
+```bash
+export OPENAI_API_KEY="sk-..."
+```
+
+### Uso
+
+```rust
+use memvid_core::api_embed::{OpenAIConfig, OpenAIEmbedder};
+use memvid_core::types::embedding::EmbeddingProvider;
+
+// Usar el modelo por defecto (text-embedding-3-small)
+let config = OpenAIConfig::default();
+let embedder = OpenAIEmbedder::new(config)?;
+
+let embedding = embedder.embed_text("hello world")?;
+assert_eq!(embedding.len(), 1536);
+
+// Usar un modelo de mayor calidad
+let config = OpenAIConfig::large();  // text-embedding-3-large (3072 dims)
+let embedder = OpenAIEmbedder::new(config)?;
+```
+
+### Modelos disponibles
+
+| Modelo                   | Dimensiones | Mejor para                       |
+| ------------------------ | ----------- | -------------------------------- |
+| `text-embedding-3-small` | 1536        | Por defecto, más rápido y económico |
+| `text-embedding-3-large` | 3072        | Máxima calidad                   |
+| `text-embedding-ada-002` | 1536        | Modelo heredado                  |
+

+  <strong>Memvid est une couche mémoire à fichier unique pour agents IA, avec récupération instantanée et mémoire long terme.</strong><br/>
+  Mémoire persistante, versionnée et portable, sans bases de données.
+</p>
+
+<h2 align="center">⭐️ Laissez une STAR pour soutenir le projet ⭐️</h2>
+</p>
+
+## Qu'est-ce que Memvid ?
+
+Memvid est un système de mémoire IA portable qui regroupe vos données, embeddings, structure de recherche et métadonnées dans un seul fichier.
+
+Au lieu d'exécuter des pipelines RAG complexes ou des bases de données vectorielles côté serveur, Memvid permet une récupération rapide directement depuis le fichier.
+
+Le résultat est une couche mémoire agnostique au modèle, sans infrastructure, qui donne aux agents IA une mémoire persistante et longue durée qu'ils peuvent emporter partout.
+
+---
+
+## Pourquoi des images vidéo ?
+
+Memvid s'inspire de l'encodage vidéo, non pas pour stocker de la vidéo, mais pour **organiser la mémoire IA en une séquence append-only ultra-efficace de Smart Frames.**
+
+Une Smart Frame est une unité immuable qui stocke le contenu avec des horodatages, des checksums et des métadonnées de base.
+Les frames sont regroupées d'une manière qui permet une compression, une indexation et des lectures parallèles efficaces.
+
+Ce design basé sur les frames permet :
+
+- Écritures append-only sans modifier ni corrompre les données existantes
+- Requêtes sur des états mémoire passés
+- Inspection type timeline de l'évolution des connaissances
+- Sécurité en cas de crash via des frames immuables et validées
+- Compression efficace grâce à des techniques adaptées de l'encodage vidéo
+
+Le résultat est un fichier unique qui se comporte comme une timeline mémoire rembobinable pour les systèmes IA.
+
+---
+
+## Concepts de base
+
+- **Moteur de mémoire vivant**
+  Ajoutez, branchez et faites évoluer la mémoire en continu entre les sessions.
+
+- **Capsule de Contexte  (`.mv2`)**
+  Capsules mémoire autonomes et partageables avec règles et expiration.
+
+- **Débogage par 'voyage temporel'**
+  Rembobinez, rejouez ou branchez n'importe quel état mémoire.
+
+- **Rappel intelligent**
+  Accès mémoire local en moins de 5 ms avec cache prédictif.
+
+- **Intelligence du codec**
+  Sélection et mise à niveau automatiques de la compression au fil du temps.
+
+---
+
+## Cas d'usage
+Memvid est une couche mémoire portable et sans serveur qui donne aux agents IA une mémoire persistante et un rappel rapide. Parce qu'il est agnostique au modèle, multimodal et fonctionne entièrement hors ligne, les développeurs utilisent Memvid pour un large éventail d'applications réelles.
+
+- Agents IA longue durée
+- Bases de connaissances d'entreprise
+- Systèmes IA offline-first
+- Compréhension de codebase
+- Agents de support client
+- Automatisation des workflows
+- Copilotes ventes et marketing
+- Assistants de connaissance personnels
+- Agents médicaux, juridiques et financiers
+- Workflows IA auditables et débogables
+- Applications sur mesure

+  <strong>मेमविड AI एजेंट के लिए एक सिंगल-फाइल मेमोरी लेयर है जिसमें तुरंत रिट्रीवल और लॉन्ग-टर्म मेमोरी होती है।</strong><br/>
+  बिना डेटाबेस के, स्थायी, वर्शन वाली और पोर्टेबल मेमोरी।
+</p>
+
+<h2 align="center">⭐️ प्रोजेक्ट को सपोर्ट करने के लिए एक स्टार दें। ⭐️</h2>
+</p>
+
+## What is Memvid?
+
+मेमविड एक पोर्टेबल AI मेमोरी सिस्टम है जो आपके डेटा, एम्बेडिंग, सर्च स्ट्रक्चर और मेटाडेटा को एक ही फ़ाइल में पैक करता है।
+
+जटिल RAG पाइपलाइन या सर्वर-आधारित वेक्टर डेटाबेस चलाने के बजाय, Memvid सीधे फ़ाइल से तेज़ी से डेटा रिट्रीव करने में मदद करता है।
+
+इसका नतीजा एक मॉडल-एग्नोस्टिक, इंफ्रास्ट्रक्चर-फ्री मेमोरी लेयर है जो AI एजेंट को परमानेंट, लॉन्ग-टर्म मेमोरी देती है जिसे वे कहीं भी ले जा सकते हैं।
+
+---
+
+## वीडियो फ़्रेम क्यों?
+
+मेमविड वीडियो एन्कोडिंग से प्रेरणा लेता है, वीडियो स्टोर करने के लिए नहीं, बल्कि**AI मेमोरी को स्मार्ट फ्रेम्स के अपेंड-ओनली, अल्ट्रा-एफ़िशिएंट सीक्वेंस के तौर पर ऑर्गनाइज़ करें।**
+
+स्मार्ट फ्रेम एक ऐसा यूनिट है जिसे बदला नहीं जा सकता, जो टाइमस्टैम्प, चेकसम और बेसिक मेटाडेटा के साथ कंटेंट स्टोर करता है।
+फ्रेम को इस तरह से ग्रुप किया जाता है जिससे कुशल कम्प्रेशन, इंडेक्सिंग और पैरेलल रीड संभव हो सके।
+
+यह फ्रेम-आधारित डिज़ाइन इन चीज़ों को संभव बनाता है:
+
+-   मौजूदा डेटा को संशोधित या दूषित किए बिना केवल डेटा जोड़ना
+-   पिछली मेमोरी स्थितियों पर प्रश्न
+-   ज्ञान कैसे विकसित होता है, इसकी टाइमलाइन-शैली में जांच
+-   प्रतिबद्ध, अपरिवर्तनीय फ्रेम के माध्यम से क्रैश सुरक्षा
+-   वीडियो एन्कोडिंग से अपनाई गई तकनीकों का उपयोग करके कुशल कम्प्रेशन।
+
+इसका नतीजा एक सिंगल फ़ाइल होती है जो AI सिस्टम के लिए रिवाइंड करने लायक मेमोरी टाइमलाइन की तरह काम करती है।
+
+---
+
+## मुख्य अवधारणाएँ
+
+-   **लिविंग मेमोरी इंजन**
+    सेशन के दौरान लगातार मेमोरी को जोड़ें, ब्रांच करें और विकसित करें।
+
+-   **कैप्सूल संदर्भ (`.mv2`)**
+    नियमों और एक्सपायरी के साथ सेल्फ-कंटेन्ड, शेयर करने लायक मेमोरी कैप्सूल।
+
+-   **टाइम-ट्रैवल डिबगिंग**
+    किसी भी मेमोरी स्टेट को रिवाइंड, रिप्ले या ब्रांच करें।
+
+-   **स्मार्ट रिकॉल**
+    प्रेडिक्टिव कैशिंग के साथ सब-5ms लोकल मेमोरी एक्सेस।
+
+-   **कोडेक इंटेलिजेंस**
+    यह समय के साथ कम्प्रेशन को ऑटो-सेलेक्ट और अपग्रेड करता है।
+
+---
+
+## उपयोग के मामले
+
+मेमविड एक पोर्टेबल, सर्वरलेस मेमोरी लेयर है जो AI एजेंट को परमानेंट मेमोरी और तेज़ रिकॉल देता है। क्योंकि यह मॉडल-एग्नोस्टिक, मल्टी-मॉडल है, और पूरी तरह से ऑफ़लाइन काम करता है, इसलिए डेवलपर्स मेमविड का इस्तेमाल कई तरह के रियल-वर्ल्ड एप्लीकेशन में कर रहे हैं।
+
+- लंबे समय तक चलने वाले AI एजेंट
+- एंटरप्राइज़ नॉलेज बेस
+- ऑफ़लाइन-फ़र्स्ट AI सिस्टम
+- कोडबेस को समझना
+- कस्टमर सपोर्ट एजेंट
+- वर्कफ़्लो ऑटोमेशन
+- सेल्स और मार्केटिंग कोपायलट
+- पर्सनल नॉलेज असिस्टेंट
+- मेडिकल, लीगल और फाइनेंशियल एजेंट
+- ऑडिट करने योग्य और डीबग करने योग्य AI वर्कफ़्लो
+- कस्टम एप्लीकेशन

+<strong>Memvidは、AIエージェントのための即時検索と長期記憶を備えた単一ファイル型メモリレイヤーです。</strong>
+</br>
+データベースを必要とせず、永続化、バージョン管理、ポータブル性を備えたメモリを実現します。
+</p>
+
+<h2 align="center">⭐️ スターで応援お願いします ⭐️</h2>
+</p>
+
+## Memvidとは？
+
+Memvidは、データ、埋め込み、検索構造、メタデータを１つのファイルにパッケージ化するポータブルAIメモリシステムです。
+
+複雑なRAGパイプラインやサーバーベースのベクトルデータベースを運用する代わりに、Memvidを使用することで直接ファイルから高速な検索が可能になります。
+
+その結果、モデルに依存せずインフラ不要のメモリレイヤーが実現し、AIエージェントはどこでも使える永続的な長期記憶を持つことができます。
+
+---
+
+## スマートフレーム (Smart Frames) とは？
+
+Memvidは、（ビデオを保存するためではなく）**追記に特化した効率的なスマートフレームのシーケンスとしてAIメモリを整理するため**に、ビデオエンコーディング技術から着想を得ています。
+
+スマートフレームは、コンテンツをタイムスタンプ、チェックサム、基本メタデータとともに保存する不変（イミュータブル）な単位です。フレームは効率的な圧縮、インデックス作成、並列読み取りができるようグループ化されています。
+
+このフレームベースの設計により、以下が可能になります。
+
+- 既存のデータを変更したり破損したりすることなくデータを追加
+- 過去のメモリ状態に対するクエリ
+- 知識がどのように進化するかをタイムライン形式で検査
+- コミットされた不変フレームによるクラッシュ耐性
+- ビデオエンコーディング技術を応用した効率的な圧縮
+
+その結果、AIシステムの「巻き戻し可能なメモリタイムライン」のように機能する単一のファイルが生成されます。
+
+---
+
+## コアコンセプト
+
+- **成長するメモリエンジン (Living Memory Engine)**
+  セッションをまたいでメモリを継続的に追加、分岐、進化させます。
+
+- **カプセル・コンテキスト (`.mv2`)**
+  ルールや有効期限を設定できる、自己完結型で共有可能なメモリカプセル。
+
+- **タイムトラベル・デバッグ**
+  任意のメモリ状態を巻き戻し、再現、または分岐させることができます。
+
+- **スマート・リコール**
+  予測キャッシングによる5ミリ秒未満のローカルメモリーアクセス。
+
+- **コーデック・インテリジェンス**
+  圧縮方式を自動選択し、時間の経過とともにアップグレードします。
+
+---
+
+## ユースケース
+
+Memvidは、AIエージェントに永続的な記憶と高速な呼び出し機能を提供するポータブルでサーバーレスなメモリレイヤーです。モデルに依存せず、マルチモーダルに対応し、完全にオフラインで動作するため、実用的なアプリケーションで幅広く利用されています。
+
+- 長期稼働AIエージェント
+- エンタープライズ向けナレッジベース
+- オフラインファーストAIシステム
+- コードベースの理解
+- カスタマーサポートエージェント
+- ワークフロー自動化
+- セールス・マーケティング支援
+- パーソナル・ナレッジ・アシスタント
+- 医療・法律・金融特化型エージェント
+- 監査・デバッグ可能なAIワークフロー
+- カスタムアプリケーション
+

+
+## Memvid란?
+
+Memvid는 데이터, 임베딩, 검색 구조 및 메타데이터를 단일 파일로 패키징하는 이식 가능한 AI 메모리 시스템입니다.
+​
+복잡한 RAG 파이프라인이나 서버 기반 벡터 데이터베이스를 실행하는 대신, Memvid는 파일에서 직접 빠른 검색을 가능하게 합니다.
+
+결과적으로 모델에 독립적이며 인프라 구조와는 독립적인 메모리 레이어로, AI 에이전트가 어디서나 휴대할 수 있는 지속적 장기 메모리를 제공합니다
+
+---
+
+## Smart Frames란?
+
+Memvid는 **AI 메모리를 추가 전용(append-only)의 초고효율 Smart Frame 시퀀스로 구성하기 위해** 비디오 인코딩에서 영감을 받았습니다.
+
+Smart Frame은 타임스탬프, 체크섬 및 기본 메타데이터와 함께 콘텐츠를 저장하는 불변 단위입니다.
+프레임은 효율적인 압축, 인덱싱 및 병렬 읽기를 허용하는 방식으로 그룹화됩니다.
+
+이러한 프레임 기반 설계는 다음을 가능하게 합니다:
+
+-   기존 데이터를 수정하거나 손상시키지 않는 추가 전용(append-only) 쓰기
+-   과거 메모리 상태에 대한 쿼리
+-   지식이 어떻게 변화하는지에 대한 타임라인 스타일 검사
+-   불변 프레임워크를 통한 크래시 안전성
+-   비디오 인코딩에서 차용한 기술을 사용한 효율적인 압축
+
+이를 위한 결과물은 AI 시스템을 위한 되감기 가능한 메모리 타임라인처럼 동작하는 단일 파일입니다.
+
+---
+
+## 주요 개념
+
+-   **실시간 변화하는 메모리 엔진**
+    세션 간에 메모리를 지속적으로 추가, 분기 및 변화시킵니다.
+
+-   **문맥 캡슐화 (`.mv2`)**
+    규칙과 만료 시간이 포함된 자립형 공유 가능 형대의 메모리 캡슐입니다.
+
+-   **시간 기반 디버깅**
+    임의의 메모리 상태로 되감기, 재생 또는 분기합니다.
+
+-   **예측 기반 호출**
+    예측 캐싱을 사용한 5ms 미만 로컬 메모리 액세스를 제공합니다.
+
+-   **코덱 인텔리전스**
+    시간 경과에 따라 압축을 자동 선택 및 업그레이드합니다.
+
+---
+
+## 이용 사례
+
+Memvid 이동 가능한 서버리스 메모리 레이어로 AI 에이전트에 지속적인 메모리와 빠른 호출을 제공합니다. 이는 모델과 독립적이고, 멀티모달을 지원하며, 인터넷을 사용하지 않으므로, 개발자들은 다양한 실제 어플리케이션에서 Memvid를 활용하고 있습니다.
+
+- 장기 실행 AI 에이전트
+- 기업 내의 지식 베이스
+- 오프라인 우선의 AI 시스템
+- 코드베이스 이해
+- 고객 지원 에이전트
+- 워크플로 자동화
+- 판매 및 마케팅 코파일럿
+- 개인 지식 어시스턴트
+- 의료, 법률 및 금융 에이전트
+- 모니터링 및 디버깅 가능한 AI 워크플로
+- 그 외의 여러 애플리케이션

+- Copy the main `README.md` as a starting point
+
+### 3. Translation Guidelines
+
+- **Keep the structure**: Maintain the same headings, sections, and formatting as the original
+- **Preserve links**: Keep all URLs and links unchanged
+- **Preserve code blocks**: Keep code examples, commands, and technical terms in English (or add comments in the target language)
+- **Update badges**: Keep badges and shields as they are (they're language-agnostic)
+- **Maintain accuracy**: Ensure technical accuracy while making the content natural in the target language
+
+### 4. Submit Your Translation
+
+1. Create a new file: `README.{language-code}.md` in this directory
+2. Translate the content while following the guidelines above
+3. Submit a pull request with:
+   - A clear description of the language being added
+   - Your name/username for attribution (if desired)
+
+## Language Codes
+
+Use standard ISO 639-1 or ISO 639-2 language codes:
+
+- `zh-CN` - Chinese (Simplified)
+- `zh-TW` - Chinese (Traditional)
+- `es` - Spanish

+- `ko` - Korean
+- `pt-BR` - Portuguese (Brazil)
+- `ru` - Russian
+- `ar` - Arabic
+- `hi` - Hindi
+- `so` - Somali
+- And more...
+
+## Maintenance
+
+Translations should be updated when the main README is significantly changed. Contributors are encouraged to keep their translations in sync with the English version.

+  <strong>Memvid is een geheugenlaag van één bestand voor AI-agenten met directe toegang en langetermijnsgeheugen.</strong><br/>
+  Volhardend en draagbaar geheugen met versiebeheer en zonder databases.
+</p>
+
+<h2 align="center">⭐️ Laat een ster achter om het project te steunen ⭐️</h2>
+</p>
+
+## Wat is Memvid?
+
+Memvid is een draagbaar AI-geheugensysteem dat uw data, embedding, zoekstructuur en metadata in één bestand opslaat.
+
+In plaats van complexe RAG pijplijnen of servergebaseerde vectordatabases te gebruiken, zal Memvid snelle toegang recht vanuit het bestand toestaan.
+
+Het resultaat is een model-agnostische, infrastructuurvrije geheugenlaag die AI-agenten een volhardende langetermijnsgeheugen geeft, die ze overal kunnen meenemen.
+
+---
+
+## Waarom videoframes?
+
+Memvid neemt inspiratie uit videos encoderen, niet om de video op te slaan, maar om **het organiseren van AI-geheugen als een ultra-efficiënte sequentie van Smart Frames waarbij je enkel kan toevoegen.**
+
+Een Smart Frame is een immutabele eenheid die content opslaat samen met zijn tijdstempels, controlesommen en basismetadata.
+Frames worden gegroupeerd in een manier die voor efficiënte compressie, indexing en parallele lezingen zorgt.
+
+Dit frame-gebaseerde design maakt het volgende mogelijk:
+
+- Append-only bijschrijven van data zonder het aanpassen of corrumperen van bestaande data
+- Zoekopdrachten over vorige geheugenstaten
+- Tijdlijn-stijl inspectie van hoe kennis evolueert
+- Crashveiligheid door de vastgelegde immutabele frames
+- Efficiënte compressie gebruikmakend van technieken aangepast uit video encoderen
+
+Het resultaat is één bestand dat werkt als een terugspoelbare geheugentijdslijn van AI-systemen.
+
+---
+
+## Basisconcepten
+
+-   **Living Memory Engine**
+    Append, vertakt en evolueert geheugen continu over sessies.
+
+-   **Capsule Context (`.mv2`)**
+    Autonome, deelbaar geheugencapsules met regels en vervalling.
+
+-   **Time-Travel Debugging**
+    Spoel terug, herspeel, of vertak elke geheugenstatus.
+
+-   **Smart Recall**
+    Sub-5ms lokale geheugentoegang met voorspelbare caching.
+
+-   **Codec Intelligence**
+    Selecteert en verbetert automatisch de compressie doorheen de tijd.
+
+---
+
+## Gebruiksgevallen
+
+Memvid is een draagbare, serverloze geheugenlaag dat AI-agenten een volhardend geheugen en snelle herroepingen geeft. Door zijn model-agnostische, multi-modale en het feit dat het volledig offline werkt, gebruiken ontwikkelaars het over een wijd scala aan real-world applicaties.
+
+-   Lang werkende AI-agenten
+-   Kennisbanken voor ondernemingen
+-   Offline-First AI-systemen
+-   Codebase-begrip
+-   Klantenondersteuningsagenten
+-   Automatisering van de workflow
+-   Verkoop- en marketingcopiloten
+-   Persoonlijke Kennisassistenten
+-   Medische, juridische en financiële adviseurs
+-   Controleerbare en debugbare AI-workflows
+-   Aangepaste toepassingen

+
+## 什么是 Memvid？
+
+Memvid 是可移植的 AI 记忆系统，将数据、嵌入向量、搜索结构和元数据打包成单个文件。
+
+无需运行复杂的 RAG 管道或基于服务器的向量数据库，Memvid 支持直接从文件进行快速检索。
+
+结果是模型无关、无基础设施的记忆层，让 AI 智能体拥有可随身携带的持久化长期记忆。
+
+     
+## 什么是 Smart Frames？
+
+Memvid 借鉴视频编码的理念，不是为了存储视频，而是**将 AI 记忆组织为仅追加、超高效序列的 Smart Frames。**
+
+Smart Frame 是存储内容以及时间戳、校验和和基本元数据的不可变单元。
+帧以允许高效压缩、索引和并行读取的方式分组。
+
+这种基于帧的设计支持：
+
+-   仅追加写入，不修改或破坏现有数据
+-   对过去记忆状态的查询
+-   知识演化的时间轴式检查
+-   通过基于提交的不可变帧应对崩溃
+-   使用基于视频编码技术的高效压缩
+
+结果是一个表现为 AI 系统可追溯记忆时间线的单文件。
+
+
+## 核心概念
+
+-   **Living Memory Engine**
+    持续追加、分支和跨会话演进记忆。
+
+-   **Capsule Context (`.mv2`)**
+    自包含、可共享的记忆胶囊，带规则和过期时间。
+
+-   **Time-Travel Debugging**
+    回溯、重放或分支化任何记忆状态。
+
+-   **Smart Recall**
+    小于 5ms 本地记忆访问，具备预测性缓存。
+
+-   **Codec Intelligence**
+    随时间自动选择和升级压缩。
+
+
+## 使用场景
+
+Memvid 是无服务器便携记忆层，为 AI 智能体提供持久记忆和快速召回。由于它是模型无关、多模态且完全离线工作，开发者正在各种现实应用中广泛的使用 Memvid。
+
+-   长期运行的 AI 智能体
+-   企业知识库
+-   离线优先 AI 系统
+-   代码库理解
+-   客户支持智能体
+-   工作流自动化
+-   销售与营销助手
+-   个人知识助理
+-   医疗、法律和金融智能体
+-   可审计和可调试的 AI 工作流
+-   自定义应用
+
+

+
+let transcriber = WhisperTranscriber::new(&config)?;
+let result = transcriber.transcribe_file("audio.mp3")?;
+println!("{}", result.text);
+```
+
+
+## 文本嵌入模型
+
+`vec` 功能包括使用 ONNX 模型的本地文本嵌入支持。在使用本地文本嵌入之前，您需要手动下载模型文件。
+
+### 快速开始：BGE-small（推荐）
+
+下载默认 BGE-small 模型（384 维，快速高效）：
+
+```bash
+mkdir -p ~/.cache/memvid/text-models
+
+# 下载 ONNX 模型
+curl -L 'https://huggingface.co/BAAI/bge-small-en-v1.5/resolve/main/onnx/model.onnx' \
+  -o ~/.cache/memvid/text-models/bge-small-en-v1.5.onnx
+
+# 下载分词器
+curl -L 'https://huggingface.co/BAAI/bge-small-en-v1.5/resolve/main/tokenizer.json' \
+  -o ~/.cache/memvid/text-models/bge-small-en-v1.5_tokenizer.json
+```
+
+### 可用模型
+
+| 模型 | 维度 | 大小 | 最适合 |
+| ------------------------ | ---------- | ------ | --------------- |
+| `bge-small-en-v1.5` | 384 | ~120MB | 默认，快速 |
+| `bge-base-en-v1.5` | 768 | ~420MB | 更好的质量 |
+| `nomic-embed-text-v1.5` | 768 | ~530MB | 多用途任务 |
+| `gte-large` | 1024 | ~1.3GB | 最高质量 |
+
+### 其他模型
+
+**BGE-base**（768 维）：
+```bash
+curl -L 'https://huggingface.co/BAAI/bge-base-en-v1.5/resolve/main/onnx/model.onnx' \
+  -o ~/.cache/memvid/text-models/bge-base-en-v1.5.onnx
+curl -L 'https://huggingface.co/BAAI/bge-base-en-v1.5/resolve/main/tokenizer.json' \
+  -o ~/.cache/memvid/text-models/bge-base-en-v1.5_tokenizer.json
+```
+
+**Nomic**（768 维）：
+```bash
+curl -L 'https://huggingface.co/nomic-ai/nomic-embed-text-v1.5/resolve/main/onnx/model.onnx' \
+  -o ~/.cache/memvid/text-models/nomic-embed-text-v1.5.onnx
+curl -L 'https://huggingface.co/nomic-ai/nomic-embed-text-v1.5/resolve/main/tokenizer.json' \
+  -o ~/.cache/memvid/text-models/nomic-embed-text-v1.5_tokenizer.json
+```
+
+**GTE-large**（1024 维）：
+```bash
+curl -L 'https://huggingface.co/thenlper/gte-large/resolve/main/onnx/model.onnx' \
+  -o ~/.cache/memvid/text-models/gte-large.onnx
+curl -L 'https://huggingface.co/thenlper/gte-large/resolve/main/tokenizer.json' \
+  -o ~/.cache/memvid/text-models/gte-large_tokenizer.json
+```
+
+### 在代码中使用
+
+```rust
+use memvid_core::text_embed::{LocalTextEmbedder, TextEmbedConfig};
+use memvid_core::types::embedding::EmbeddingProvider;
+
+// 使用默认模型（BGE-small）
+let config = TextEmbedConfig::default();
+let embedder = LocalTextEmbedder::new(config)?;
+
+let embedding = embedder.embed_text("hello world")?;
+assert_eq!(embedding.len(), 384);
+
+// 使用不同模型
+let config = TextEmbedConfig::bge_base();
+let embedder = LocalTextEmbedder::new(config)?;
+```
+
+有关相似度计算和搜索排名的完整示例，请参见 `examples/text_embedding.rs`。
+
+### 模型一致性
+
+为防止意外地模型混合（例如，使用 OpenAI 嵌入查询 BGE-small 索引），您可以将 Memvid 实例显式绑定到特定模型名称：
+
+```rust
+// 将索引绑定到特定模型。
+// 如果之前使用不同模型创建索引将返回错误。
+mem.set_vec_model("bge-small-en-v1.5")?;
+```
+
+绑定是持久化的。一旦设置，将来尝试使用不同模型名称将快速失败并返回 `ModelMismatch` 错误。
+
+
+
+## API 嵌入（OpenAI）
+
+`api_embed` 功能使用 OpenAI 的 API 启用基于云的嵌入生成。
+
+### 设置
+
+设置您的 OpenAI API 密钥：
+
+```bash
+export OPENAI_API_KEY="sk-..."
+```
+
+### 用法
+
+```rust
+use memvid_core::api_embed::{OpenAIConfig, OpenAIEmbedder};
+use memvid_core::types::embedding::EmbeddingProvider;
+
+// 使用默认模型（text-embedding-3-small）
+let config = OpenAIConfig::default();
+let embedder = OpenAIEmbedder::new(config)?;
+
+let embedding = embedder.embed_text("hello world")?;
+assert_eq!(embedding.len(), 1536);
+
+// 使用更高质量模型
+let config = OpenAIConfig::large();  // text-embedding-3-large (3072 维)
+let embedder = OpenAIEmbedder::new(config)?;
+```
+
+### 可用模型
+
+| 模型 | 维度 | 最适合 |
+| ------------------------ | ---------- | -------------------------- |
+| `text-embedding-3-small` | 1536 | 默认，最快，最便宜 |
+| `text-embedding-3-large` | 3072 | 最高质量 |
+| `text-embedding-ada-002` | 1536 | 传统模型 |
+
+有关完整示例，请参见 `examples/openai_embedding.rs`。

-file_chat.py - Enhanced script for testing MemvidChat with external files
-
-This script allows you to:
-1. Create a memory video from your own files with configurable parameters
-2. Chat with the created memory using different LLM providers
-3. Store results in output/ directory to avoid contaminating the main repo
-4. Handle FAISS training issues gracefully
-5. Configure chunking and compression parameters
-
-Usage:
-    python file_chat.py --input-dir /path/to/documents --provider google
-    python file_chat.py --files file1.txt file2.pdf --provider openai --chunk-size 2048
-    python file_chat.py --load-existing output/my_memory --provider google
-    python file_chat.py --input-dir ~/docs --index-type Flat --codec h265
-
-Examples:
-    # Create memory from a directory and chat with Google
-    python file_chat.py --input-dir ~/Documents/research --provider google
-
-    # Create memory with custom chunking for large documents
-    python file_chat.py --files report.pdf --chunk-size 2048 --overlap 32 --provider openai
-
-    # Use Flat index for small datasets (avoids FAISS training issues)
-    python file_chat.py --files single_doc.pdf --index-type Flat --provider google
-
-    # Load existing memory and continue chatting
-    python file_chat.py --load-existing output/research_memory --provider google
-
-    # Create memory with H.265 compression
-    python file_chat.py --input-dir ~/docs --codec h265 --provider anthropic

+# Memvid Installer
+
+Official installer for Memvid (v1).
+
+## What it does
+
+The installer automatically checks for and installs required dependencies, then installs Memvid globally:
+
+- **System dependencies** (Linux only):
+  - **ca-certificates** - SSL certificate bundle
+  - **curl** - Command-line tool for downloading files
+  - **openssl** or **libssl3** - SSL/TLS library
+- **git** - Version control system
+- **node** (LTS) - JavaScript runtime
+- **npm** - Package manager (comes with node)
+- **memvid** - Installed globally via `npm install -g memvid-cli@latest`
+
+The installer only installs missing tools (no upgrades in v1). If a tool is already installed, it will be detected and skipped.
+
+**Important notes:**
+- On macOS, if Xcode Command Line Tools are missing, the installer will prompt you to install them and then exit. You'll need to complete the Xcode installation and run the installer again.
+- The installer will show you what will be installed and ask for confirmation before proceeding.
+- On Linux, Node.js LTS is installed via the NodeSource repository for Debian/Ubuntu and RHEL-based distributions to ensure you get the latest LTS version.
+
+## Prerequisites
+
+- **macOS**: 
+  - Homebrew must be installed (the installer will check and exit if missing)
+  - Xcode Command Line Tools (installer will prompt to install if missing)
+- **Linux**: 
+  - `sudo` access (required for package installation, except Alpine which may use `su`)
+  - One of the supported package managers (apt, dnf, pacman, or apk)
+- **Windows**: 
+  - winget (Windows Package Manager) - comes with Windows 11, or install from https://aka.ms/getwinget
+
+## Supported Platforms
+
+- **macOS** - Uses Homebrew (requires Xcode Command Line Tools)
+- **Linux** - Multiple distributions supported:
+  - **Debian/Ubuntu** - Uses apt (Node.js installed via NodeSource repository)
+  - **Fedora/RHEL/CentOS/Rocky/AlmaLinux** - Uses dnf (Node.js installed via NodeSource repository)
+  - **Arch/Manjaro** - Uses pacman
+  - **Alpine** - Uses apk
+- **Windows** - Requires winget (Windows Package Manager)
+
+## Installation
+
+### macOS / Linux
+
+**Quick install** (recommended):
+```bash
+curl -fsSL https://raw.githubusercontent.com/memvid/memvid/main/install/install.sh | bash
+```
+
+**Download and run locally**:
+```bash
+curl -fsSL https://raw.githubusercontent.com/memvid/memvid/main/install/install.sh -o install.sh
+chmod +x install.sh
+./install.sh
+```
+
+**Non-interactive mode** (for CI/CD):
+The installer can run without user interaction when piped via `curl | bash`. It will proceed automatically if no terminal is detected.
+
+### Windows
+
+Open PowerShell and run:
+
+```powershell
+irm https://raw.githubusercontent.com/memvid/memvid/main/install/install.ps1 | iex
+```
+
+Or download and run:
+
+```powershell
+.\install.ps1
+```
+
+## Security
+
+These scripts are open source and readable. Before running, you can:
+
+1. Review the script contents on GitHub
+2. Download and inspect locally
+3. Run with appropriate permissions
+
+The installer will:
+- Show what will be installed before proceeding
+- Ask for confirmation before installing anything
+- Use only system package managers (no third-party installers)
+- Print clear status messages for each step
+
+## Verification
+
+After installation, verify it worked:
+
+```bash
+memvid --version
+```
+
+## Troubleshooting
+
+If installation fails:
+
+1. **macOS**:
+   - Ensure Homebrew is installed: `/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"`
+   - If Xcode CLI Tools installation was prompted, complete it and run the installer again
+   - If `node` command is not found after installation, you may need to restart your terminal or source your shell config file
+
+2. **Linux**:
+   - Check that you have `sudo` access (or run as root on Alpine)
+   - Ensure your package manager is up to date (`sudo apt-get update`, `sudo dnf check-update`, etc.)
+   - If Node.js installation fails, check that curl and ca-certificates are installed
+   - Verify npm global bin directory is in your PATH: `npm config get prefix`
+
+3. **Windows**:
+   - Ensure winget is installed (comes with Windows 11, or install from https://aka.ms/getwinget)
+   - Run PowerShell as Administrator if needed
+
+4. **General**:
+   - Check that npm global bin directory is in your PATH: `npm list -g memvid-cli`
+   - Try running `memvid --version` to verify installation
+   - On Linux, you may need to use `sudo` for global npm installs
+
+For issues, please open an issue on GitHub.

-
-# Create video memory from text chunks
-chunks = ["Important fact 1", "Important fact 2", "Historical event details", ...]
-encoder = MemvidEncoder()
-encoder.add_chunks(chunks)
-encoder.build_video("memory.mp4", "memory_index.json")
-
-# Chat with your memory
-chat = MemvidChat("memory.mp4", "memory_index.json")
-chat.start_session()
-response = chat.chat("What do you know about historical events?")
-print(response)
-```
-
-### Building Memory from Documents
-```python
-from memvid import MemvidEncoder
-import os
-
-# Load documents
-encoder = MemvidEncoder(chunk_size=512, overlap=50)
-
-# Add text files
-for file in os.listdir("documents"):
-    with open(f"documents/{file}", "r") as f:
-        encoder.add_text(f.read(), metadata={"source": file})
-
-# Build optimized video
-encoder.build_video(
-    "knowledge_base.mp4",
-    "knowledge_index.json",
-    fps=30,  # Higher FPS = more chunks per second
-    frame_size=512  # Larger frames = more data per frame
-)
-```
-
-### Advanced Search & Retrieval
-```python
-from memvid import MemvidRetriever
-
-# Initialize retriever
-retriever = MemvidRetriever("knowledge_base.mp4", "knowledge_index.json")
-
-# Semantic search
-results = retriever.search("machine learning algorithms", top_k=5)
-for chunk, score in results:
-    print(f"Score: {score:.3f} | {chunk[:100]}...")
-
-# Get context window
-context = retriever.get_context("explain neural networks", max_tokens=2000)
-print(context)
-```
-
-### Interactive Chat Interface
-```python
-from memvid import MemvidInteractive
-
-# Launch interactive chat UI
-interactive = MemvidInteractive("knowledge_base.mp4", "knowledge_index.json")
-interactive.run()  # Opens web interface at http://localhost:7860
-```
-
-### Testing with file_chat.py
-The `examples/file_chat.py` script provides a comprehensive way to test Memvid with your own documents:
-
-```bash
-# Process a directory of documents
-python examples/file_chat.py --input-dir /path/to/documents --provider google
-
-# Process specific files
-python examples/file_chat.py --files doc1.txt doc2.pdf --provider openai
-
-# Use H.265 compression (requires Docker)
-python examples/file_chat.py --input-dir docs/ --codec h265 --provider google
-
-# Custom chunking for large documents
-python examples/file_chat.py --files large.pdf --chunk-size 2048 --overlap 32 --provider google
-
-# Load existing memory
-python examples/file_chat.py --load-existing output/my_memory --provider google
-```
-
-### Complete Example: Chat with a PDF Book
-```bash
-# 1. Create a new directory and set up environment
-mkdir book-chat-demo
-cd book-chat-demo
-python -m venv venv
-source venv/bin/activate  # On Windows: venv\Scripts\activate
-
-# 2. Install dependencies
-pip install memvid PyPDF2
-
-# 3. Create book_chat.py
-cat > book_chat.py << 'EOF'
-from memvid import MemvidEncoder, chat_with_memory
-import os
-
-# Your PDF file
-book_pdf = "book.pdf"  # Replace with your PDF path
-
-# Build video memory
-encoder = MemvidEncoder()
-encoder.add_pdf(book_pdf)
-encoder.build_video("book_memory.mp4", "book_index.json")
-
-# Chat with the book
-api_key = os.getenv("OPENAI_API_KEY")  # Optional: for AI responses
-chat_with_memory("book_memory.mp4", "book_index.json", api_key=api_key)
-EOF
-
-# 4. Run it
-export OPENAI_API_KEY="your-api-key"  # Optional
-python book_chat.py
-```
-
-## 🛠️ Advanced Configuration
-
-### Custom Embeddings
-```python
-from sentence_transformers import SentenceTransformer
-
-# Use custom embedding model
-custom_model = SentenceTransformer('sentence-transformers/all-mpnet-base-v2')
-encoder = MemvidEncoder(embedding_model=custom_model)
-```
-
-### Video Optimization
-```python
-# For maximum compression
-encoder.build_video(
-    "compressed.mp4",
-    "index.json",
-    fps=60,  # More frames per second
-    frame_size=256,  # Smaller frames
-    video_codec='h265',  # Better compression
-    crf=28  # Compression quality (lower = better quality)
-)
-```
-
-### Distributed Processing
-```python
-# Process large datasets in parallel
-encoder = MemvidEncoder(n_workers=8)
-encoder.add_chunks_parallel(massive_chunk_list)
-```
-
-## 🐛 Troubleshooting
-
-### Common Issues
-
-**ModuleNotFoundError: No module named 'memvid'**
-```bash
-# Make sure you're using the right Python
-which python  # Should show your virtual environment path
-# If not, activate your virtual environment:
-source venv/bin/activate  # On Windows: venv\Scripts\activate
-```
-
-**ImportError: PyPDF2 is required for PDF support**
-```bash
-pip install PyPDF2
-```
-
-**LLM API Key Issues**
-```bash
-# Set your API key (get one at https://platform.openai.com)
-export GOOGLE_API_KEY="AIzaSyB1-..."  # macOS/Linux
-# Or on Windows:
-set GOOGLE_API_KEY=AIzaSyB1-...
-```
-
-**Large PDF Processing**
-```python
-# For very large PDFs, use smaller chunk sizes
-encoder = MemvidEncoder()
-encoder.add_pdf("large_book.pdf", chunk_size=400, overlap=50)
-```
