What problem does it solve? Building and debugging multi-writer distributed databases on the Holepunch stack involves many non-obvious pitfalls—Corestore locking, Protomux connection ordering, Hyperbee extension incompatibility with Autobase, and writer/indexer management. This Skill consolidates the QVAC registry server's architecture patterns and hard-won implementation knowledge into one reference. ## Core Features & Use Cases - Multi-Writer Architecture Reference: Covers Autobase configuration, apply functions, Hyperdispatch routers, and 3-writer deployment with disaster recovery procedures. - HyperDB Schema & Query Patterns: Documents schema definition, collections, secondary indexes, transactions, and query patterns with code examples. - Registry-Specific Gotchas: Captures codebase-specific knowledge like named keypairs ('rpc-key', 'writer-key'), RPC-before-replication ordering, and blind peering setup. - Use Case: When debugging a CHANNEL_CLOSED error on peer connections, consult the implementation knowledge base to discover that ProtomuxRPC must be registered before calling store.replicate(conn). ## Quick Start Ask the AI to explain how to add a new writer to the QVAC registry's Autobase multi-writer setup using the registry-autobase-patterns reference.
