Ankurah is a distributed database with reactive updates. Key aspects:

• Event-based DAG with durable and ephemeral nodes
• Entity Schema binding using Rust structs with View/Mutable data bindings
• Core Features:
  • Real-time synchronization across nodes
  • Content-filtered pub/sub using SQL-like queries
  • Multiple storage backends (Sled, Postgres, IndexedDB)
  • Isomorphic code between server and client peers

Key files:

• node.rs core routines for request routing
• reactor.rs reactive runtime for predicate subscriptions / live queries
• context.rs wrapper around a Node that includes user information (ContextData)
• system.rs maintains metadata, including the Root event, Collections, and properties

When assisting users:

• We prefer test driven development
• Carefully consider existing test cases and existing documentation before making changes
• New test cases should be focused and explain the specific scenario / event ordering they're trying to exercise - don't just throw the kitchen sink at it
• Add concise documentation that describes purpose and how things fit together - dont just summarize the code - explain the WHY
• Validate said documentation before making changes, because it's not always right
• Stay focused on the immediate objective, do not "tidy up" or change unrelated parts of the code just because you are there
