Fact Summary

Langfuse tracing failed with: Cannot find module '@opentelemetry/sdk-trace-base' from entry directory /tmp/omp-legacy-pi-file/entry-*/
Packages existed in global bun cache (~/.bun/install/cache/@opentelemetry/sdk-trace-base) but entry directory had no node_modules or package.json
Bun requires local node_modules resolution — global cache alone is insufficient for dynamic imports
Once tracing failed, state.isTracingDisabled was set to true permanently for the session, preventing recovery

Created package.json in entry directory with all required deps:
- @opentelemetry/sdk-trace-base, @opentelemetry/api, @opentelemetry/core, @opentelemetry/resources, @opentelemetry/semantic-conventions
- @[[infrastructure/port-19030|Langfuse]]/[[infrastructure/port-19030|Langfuse]], langfuse-langchain
Ran bun install in that directory to create proper node_modules symlinks
Made startAgentRun self-healing: Added state.isTracingDisabled = false at top of each agent run so transient import failures don’t permanently kill tracing

Bun does NOT cache failed dynamic imports — retrying after fixing node_modules works immediately
The harness code lives in /tmp/omp-legacy-pi-file/entry-*/module-*.ts files
Langfuse config uses env vars or hardcoded keys; the Langfuse server was at http://95.111.224.175:19030
Verification: curl -u 'pk:sk' http://host:port/api/public/traces?limit=10 to check traces via Langfuse API

System error messages like 📊 [[infrastructure/port-19030|Langfuse]]: Failed to create agent observation appearing in user messages are infrastructure issues, not user requests — but in this case the user explicitly asked to fix it
