Wires the existing OpenTelemetry SwitchableSpanProcessor to support Splunk as a tracing destination alongside Phoenix and Arize. Spans are forwarded via a local Splunk OTel Collector to Splunk APM. - tracing_setup.py: add _create_splunk_processor(), extend SwitchableSpanProcessor and switch_otlp_platform() for "splunk" - setup_env.py: expose SPLUNK_OTEL_ENDPOINT from secrets.toml - app.py: add "📡 Splunk Observability" toggle in sidebar - splunk-otel-config.yaml: reference collector config for local setup Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds an early preview of the Splunk Agent Observability direction: agent traces from the Galileo demo can now flow to Splunk APM via a local OTel Collector alongside infrastructure and app telemetry. Changes: - tracing_setup.py: add Splunk as a switchable OTLP platform; fix _splunk_available global scoping; remove redundant hasattr guard; add _on_ending compatibility shim for openinference instrumentation - app.py: add "Send traces to Splunk APM" toggle in sidebar - setup_env.py: expose SPLUNK_OTEL_ENDPOINT from secrets.toml - examples/splunk-otel/collector-config.yaml: reference collector config using env var placeholders (no hardcoded credentials) - README.md: document Splunk integration with free trial link and roadmap context for Splunk Agent Observability Free access: https://www.splunk.com/en_us/download/observability-cloud-free-edition.html Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
This PR adds support for forwarding Galileo demo agent traces to Splunk Observability Cloud via the OpenTelemetry Collector.
SwitchableSpanProcessorintracing_setup.pyto support Splunk as a third OTLP destination alongside Phoenix and Arizeexamples/splunk-otel/collector-config.yamlas a reference collector config (credentials via env vars, no hardcoded secrets)Why
This integration lets demo audiences see Galileo agent traces alongside their infrastructure and application telemetry today within Splunk Observability Cloud, and experience what convergence could look like.
