-# OptiTransfer Data
-Premium web corpora for LLM pre-training, fine-tuning, RAG, and multilingual NLP.
 ---
-## About
-OptiTransfer Data is the data division of [OptiTransfer AG](https://optitransfer.ch), a Swiss-registered technology company. We produce compliance-ready, quality-scored web datasets for AI teams building in regulated markets.
-Every dataset ships with:
-- Full data provenance and SHA256 verification
-- PII detection and redaction
-- Multi-dimensional quality scoring (0-100 per document)
-- EU AI Act and Swiss FADP compliance documentation
-- Croissant metadata for ML interoperability
-- Multiple export formats (Parquet, JSONL, language splits, RAG chunks)
 ---
-## Available Datasets
-### *.ch Swiss Web Premium (A+)
-110,491 documents | 78 fields | 554 MB total | Quality score: 62.3 mean
-The flagship Swiss web corpus, extracted and quality-scored from the .ch ccTLD. Multilingual coverage across German (61.2%), French (19.0%), English (10.5%), Italian (4.7%), and additional languages. Nine-component quality model with full provenance chain.
-**Best suited for:** LLM Pre-Training, Supervised Fine-Tuning (SFT), Retrieval-Augmented Generation (RAG), Multilingual NLP, German Language Models, French Language Models, Swiss Market AI, Regulatory Compliance (EU AI Act), Domain-Specific Training, Web Corpus Research, Text Classification, Summarisation, Question Answering, Translation
-**Formats:** Parquet (7 shards) | JSONL (7 shards) | Language Splits (DE, FR, EN, IT) | RAG Chunks (4 files)
-| Repository | Description | Access |
-|---|---|---|
-| [swiss-web-premium-ch](https://huggingface.co/datasets/OptiTransferData/swiss-web-premium-ch) | 10,000-record stratified sample with full documentation and QA report | Gated (evaluation) |
-| [swiss-web-premium-ch-full](https://huggingface.co/datasets/OptiTransferData/swiss-web-premium-ch-full) | Complete 110,491-record production dataset | Gated (licensed) |
 ---
-## Data Pipeline
-All datasets are processed through the OptiTransfer pipeline:
-1. **Source Selection** -- Common Crawl filtered by ccTLD and domain trust scoring
-2. **Extraction** -- Text extraction with deduplication, language detection, and structural analysis
-3. **Quality Scoring** -- Nine-component quality model producing a composite 0-100 score per document
-4. **Enrichment** -- Content categorisation, trust tier assignment, academic/news detection, skill tagging
-5. **Compliance** -- PII scanning, redaction, and regulatory documentation
-6. **Verification** -- SHA256 checksums, QA reporting, and independent audit readiness
 ---
-## Quality Assurance
-Each dataset is accompanied by a full QA report covering:
-- Pipeline configuration and processing parameters
-- Quality score distributions and statistical analysis
-- Language detection accuracy and coverage
-- Content categorisation breakdown
-- PII detection results
-- Domain trust tier analysis
-- SHA256 integrity verification
-QA reports are available in both the sample and full product repositories.
 ---
-## Licensing
-All datasets are available under the OptiTransfer Commercial License. Sample repositories provide gated evaluation access. Full datasets require a commercial license agreement.
-**Payment methods:** Bank Transfer (SEPA/SWIFT) | TWINT | Cryptocurrency (BTC / ETH / SOL)
-For pricing, volume licensing, or custom extraction requests, contact [data@optitransfer.ch](mailto:data@optitransfer.ch).

+# Optitransfer
+Convergent intelligence infrastructure for distributed AI systems. Patent-pending.
 ---
+## What We Build
+**[crdt-merge](https://github.com/mgillr/crdt-merge)** — the open-source library that makes AI model merging deterministic, conflict-free, and mathematically guaranteed to converge. Any number of models, any merge order, provably correct result. Every time.
+crdt-merge applies Conflict-Free Replicated Data Type theory to neural network weight spaces. The result: models that merge like distributed databases — without coordination, without data loss, without conflicts.
+**Patent Pending:** UK Application GB 2607132.4
 ---
+## Core Technology
+| Capability | What It Does |
+|---|---|
+| **26 Merge Strategies** | From simple averaging to adaptive trust-weighted convergence |
+| **Merkle Provenance** | Every weight, every merge, cryptographically tracked |
+| **Causal Ordering** | Vector clocks ensure correct merge sequence across distributed nodes |
+| **Byzantine Tolerance** | Resilient against adversarial or faulty participants |
+| **Delta Compression** | Ship only what changed — not entire models |
+| **Format Agnostic** | PyTorch, TensorFlow, SafeTensors, GGUF, NumPy |
 ---
+## Live Demos
+| Space | Description |
+|---|---|
+| **[crdt-merge](https://huggingface.co/spaces/Optitransfer/crdt-merge)** | Flagship — merge real models with full provenance and compliance |
+| **[Convergence Lab](https://huggingface.co/spaces/Optitransfer/convergence-lab)** | Test all 26 strategies, visualise convergence, run experiments |
+| **[Data Playground](https://huggingface.co/spaces/Optitransfer/crdt-merge-data)** | CRDT merging applied to tabular data |
+| **[Federation](https://huggingface.co/spaces/Optitransfer/crdt-merge-federation)** | Multi-node gossip convergence simulation |
 ---
+## Getting Started
+```bash
+pip install crdt-merge
+```
+```python
+from crdt_merge import CRDTMergeState
+state = CRDTMergeState()
+state.load_model("model_a.safetensors")
+state.load_model("model_b.safetensors")
+result = state.merge(strategy="dare_ties")
+result.save("merged.safetensors")
+```
 ---
+## Data Products
+Optitransfer also produces compliance-ready, quality-scored web corpora for AI training.
+| Dataset | Records | Access |
+|---|---|---|
+| [Swiss Web Premium (A+)](https://huggingface.co/datasets/OptiTransferData/swiss-web-premium-ch) | 110,491 | [Sample](https://huggingface.co/datasets/OptiTransferData/swiss-web-premium-ch) \| [Full](https://huggingface.co/datasets/OptiTransferData/swiss-web-premium-ch-full) |
