Laminar Migrate Observability

Workflow

1. Identify the current provider, runtime, and entrypoints. Capture trace boundaries and existing context (user/session IDs, tags, metadata, redaction rules).
2. Choose the migration approach:
   • If OpenTelemetry is already in use, keep instrumentation and reconfigure the OTLP exporter to Laminar.
   • Otherwise, replace wrappers/decorators with Laminar observe() / @observe() or manual spans, and enable provider auto-instrumentation.
   • Avoid double-instrumentation.
3. Install Laminar with the repo's package manager. Add LMNR_PROJECT_API_KEY (and base URL if self-hosted) to env examples.
4. Map concepts and naming: stable span names, low-cardinality tags, IDs in metadata.
5. Verify: run a representative flow and confirm root span, child spans, and tags in the UI. Ensure trace context is preserved end-to-end.
