feat: Reduce Cytiva Biacore T200 Control memory usage with cycle streaming#1164
Merged
Conversation
…aming - Implement decode_data_streaming() generator that yields cycles one at a time - Process cycles individually instead of concatenating all DataFrames at once - Maintain backward compatibility with decode_data() wrapper - Memory usage reduced by 19.6% (134.24 MB → 107.87 MB, 84.6x → 68.0x amplification) - All tests pass with no changes to golden files This addresses memory amplification concerns identified in parser audit, where T200 Control showed 133x average amplification (agent-reported via memory_profiler). Actual measurements with tracemalloc show 84.6x on main, reduced to 68.0x with streaming.

Summary
Implements cycle streaming for Cytiva Biacore T200 Control parser to reduce memory usage by 19.6%.

This addresses memory amplification concerns identified in the parser audit. The T200 Control parser showed 133x average amplification with memory_profiler (agent-reported). Accurate measurements with tracemalloc show 84.6x on main, reduced to 68.0x with streaming.
