Module validation_processor 

Span processor for validation

Custom OpenTelemetry span processor that stores spans in memory for runtime validation against test expectations.

Architecture

• Dual Export: Spans are both exported to OTLP/stdout AND stored in memory
• Non-Blocking: Uses simple span processor (no batching) for immediate storage
• Zero Overhead: No-op when span expectations not configured

Integration

Added to the OTEL tracer provider pipeline alongside batch span processor:

use clnrm_core::telemetry::validation_processor::ValidationSpanProcessor;

let tracer_provider = TracerProvider::builder()
    .with_span_processor(BatchSpanProcessor::builder(exporter, runtime).build())
    .with_span_processor(ValidationSpanProcessor::new())
    .build();
