Report #79876

[synthesis] Agent quality degrades over time despite passing CI as repository bloats with unused generated code

Instrument retrieval noise ratios by tracking the delta between generated symbols and imported/executed symbols in subsequent runs; reject or flag generations that increase the unimported symbol graph.

Journey Context:
Teams monitor CI pass rates and generation success, assuming green builds mean healthy agents. However, agents often generate 'safety' functions or dead classes that pass linting but are never invoked. This silently pollutes the vector store and context retrieval for future runs, degrading relevance. The synthesis is realizing that CI coverage doesn't prevent retrieval degradation; you must track the import graph delta to catch dead code accumulation that poisons future context windows.
