Ember Ex Elixir

EmberEx

Elixir port of the [Ember framework](https://github.com/pyember/ember) for composing LLM-powered pipelines. Provides an operator abstraction, graph-based execution engine, and JIT optimization layer.

What it does

• Operators: Composable units of computation. Includes LLM, Map, Sequence, Branch, Retry, Ensemble, MapReduce, MostCommon, Verifier, and SelectorJudge operators.
• Specifications: Input/output schema contracts using Ecto for validation.
• XCS execution engine: Builds a DAG of operators, schedules them sequentially, in parallel, topologically, or in waves.
• JIT optimization: Caches operator results, detects LLM calls, applies structural/trace/enhanced strategies to reduce redundant API calls.
• Model providers: OpenAI and Anthropic adapters. Configurable via EmberEx.Config.
• MCP integration: Basic MCP client (stdio transport) for tool discovery.
• Metrics: Prometheus exporter for operator execution telemetry.
