…tions Added `@functools.lru_cache` to `_compiled_context_lexicon` in `openmed/openmed/clinical/context.py` and section aliases in `openmed/openmed/clinical/lexicons/section_headers.py`. Modified dictionary return types to `types.MappingProxyType` to prevent downstream mutation of cached instances. Recorded performance learning in `.jules/bolt.md`.

💡 What: Added
@functools.lru_cacheto_compiled_context_lexiconandsection_header_aliasesfunctions. Modified return types of cached mappings totypes.MappingProxyTypeto guarantee immutability.🎯 Why: In openmed text processing pipelines, compiling deterministic regex patterns or assembling lexicons dynamically inside functions called during string/span evaluations created a severe performance bottleneck.
📊 Impact: Eliminates redundant regex compilation during clinical text pipeline execution, reducing CPU overhead during span classifications (e.g. temporality, negation). Memory footprint is extremely minimal (maxsize=16 per cache).
🔬 Measurement: Verify by monitoring NLP extraction pipeline throughput. Test passes locally (
uv run pytest tests/unit/clinical).PR created automatically by Jules for task 8075981499430453367 started by @zrt219
