Database v0.1.0\nConnected to: ./movies.zyx\nType help for commands, exit to quit.\n```\n\nCreate nodes and relationships:\n```\nZYX\u003e CREATE (m:Movie {title: 'The Matrix', year: 1999}),\n     ··· (a:Actor {name: 'Keanu Reeves'}),\n     ··· (a)-[:ACTED_IN {role: 'Neo'}]-\u003e(m);\n(0 rows, 1.23ms)\n```\n\nQuery with pattern matching:\n```\nZYX\u003e MATCH (a:Actor)-[r:ACTED_IN]-\u003e(m:Movie)\n     ··· RETURN a.name AS actor, m.title AS movie, r.role AS role;\n┌────────────────┬────────────┬──────┐\n│ actor          │ movie      │ role │\n├────────────────┼────────────┼──────┤\n│ Keanu Reeves   │ The Matrix │ Neo  │\n└────────────────┴────────────┴──────┘\n(1 row, 0.85ms)\n```\n\nAggregation:\n```\nZYX\u003e MATCH (n) RETURN count(n) AS total_nodes;\n┌─────────────┐\n│ total_nodes │\n├─────────────┤\n│ 2           │\n└─────────────┘\n(1 row, 0.42ms)\n```\n\nOr try it in the browser — [**Live Playground**](https://nexepic.github.io/zyx/en/playground) (no install required, runs via WebAssembly).\n\n## Highlights\n\n- **Cypher Query Engine** — `MATCH`, `CREATE`, `MERGE`, `WITH`, `UNION`, `UNWIND`, `CALL`, `LOAD CSV`\n- **ACID Transactions** — Write-ahead logging, crash recovery, snapshot isolation\n- **Vector Search** — HNSW index with cosine/euclidean/dot-product similarity\n- **Graph Algorithms** — PageRank, shortest path, community detection via built-in procedures\n- **Schema \u0026 Indexes** — Label indexes, property indexes, uniqueness constraints\n- **Embeddable** — C++ header-only API, C API, Python bindings (`zyxdb`), and WebAssembly\n- **Cross-Platform** — macOS, Linux, Windows\n\n## Quick Start\n\n### Install\n\n**macOS** (Homebrew):\n\n```bash\nbrew tap nexepic/zyx\nbrew install zyx\n```\n\n**Linux / Windows**: Download a pre-built binary from [Releases](https://github.com/nexepic/zyx/releases).\n\n**Build from source** (all platforms):\n\n```bash\n./scripts/run_tests.sh          # Full build + tests + coverage\n./scripts/build_release.sh      # Release build only\n```\n\nPrerequisites: C++20 compiler (Clang 14+ / GCC 11+), CMake 3.21+, Ninja, Conan 2.x, Python 3.10+\n\n### Use\n\n```bash\nzyx database create ./mydb.zyx      # Create new database\nzyx database open ./mydb.zyx        # Open existing database\nzyx database exec ./mydb.zyx q.cql  # Execute a Cypher script\nzyx import --database ./mydb.zyx \\\n  --nodes nodes.csv \\\n  --relationships rels.csv          # Bulk CSV/JSONL import\n```\n\n### Embed\n\n**C++**\n```cpp\n#include \u003czyx/zyx.hpp\u003e\n\nzyx::Database db(\"./mydb.zyx\");\ndb.open();\nauto result = db.query(\"MATCH (n) RETURN n.name LIMIT 5\");\ndb.close();\n```\n\n**Python**\n```python\nimport zyxdb\n\ndb = zyxdb.Database(\"./mydb.zyx\")\ndb.open()\nresult = db.execute(\"MATCH (n) RETURN n.name LIMIT 5\")\ndb.close()\n```\n\n##
