Group review, feedback, evaluation, observability, and entrypoint code into packages. Keep thin top-level compatibility shims for existing scripts and imports, and mirror the structure in the tests.
The standard /api/public/ingestion path feeds only the trace-upsert
queue; evalService.createEvalJobs only dispatches targetObject in
{TRACE, DATASET}. Observation rules fire exclusively from the OTel
pipeline, which this pilot does not use. The trace body already carries
review input/output via langfuse_trace, so a trace rule sees the same
material an observation rule would.
