+# Graphictac Knowledge Base Database
+
+An open, source-linked research dataset for printable media, printer workflows, and professional print-and-cut production.
+
+This repository is designed to be readable by people, search engines, AI assistants, and data tools. It publishes structured research snapshots behind the Graphictac and MAXDECALS knowledge-base program.
+
+## Dataset contents
+
+| Dataset | Rows | Purpose |
+|---|---:|---|
+| `printer_brand_research_matrix` | 6 | Maps printer brands, ink workflows, compatibility angles, and official sources. |
+| `competitor_product_research_matrix` | 8 | Maps major printable-media product families, positioning signals, compatibility context, and claim risk. |
+| `source_library` | 14 | Provides the source registry used by the two research matrices. |
+
+Every dataset is available as CSV and JSONL in [`data/`](data/). Machine-readable field definitions are in [`schema/dataset.schema.json`](schema/dataset.schema.json).
+
+## Quick start
+
+Download or clone the repository, then read a JSONL file one record per line:
+
+```python
+import json
+
+with open("data/printer_brand_research_matrix.jsonl", encoding="utf-8") as f:
+    records = [json.loads(line) for line in f if line.strip()]
+
+print(records[0])
+```
+
+## Research scope
+
+- Printer brands: Roland, Mimaki, HP Latex, Epson, Mutoh, and Canon.
+- Printable-media brands: 3M, Avery Dennison, ORAFOL / ORAJET, General Formulations, Arlon, Mactac, Briteline / Grimco, and Siser.
+- Primary use cases: printable vinyl, vehicle graphics, stickers, decals, wrap films, high-tack media, printable HTV, and printer workflow education.
+- Source policy: official manufacturer or brand-controlled product pages are preferred.
+
+## Important limitations
+
+This is a research and discovery dataset, not a certification database. Compatibility statements describe workflow context found in cited sources. They do not guarantee a specific printer, ink, profile, laminate, surface, or application combination. Always confirm current manufacturer documentation and run production testing before use.
+
+The first public release is a dated snapshot. URLs, specifications, and product availability can change after the recorded review date.
+
+## Methodology and provenance
+
+See [`METHODOLOGY.md`](METHODOLOGY.md) for collection, normalization, claim-risk, and update rules. See [`DATA_DICTIONARY.md`](DATA_DICTIONARY.md) for field definitions.
