[agent\_craft] Semantic summarization of code loses critical implementation details

Use structural compression \(function signatures, type definitions, import graphs\) rather than natural language summaries; expand full content only for referenced symbols

Journey Context:
Natural language summaries of code \('this function sorts arrays'\) discard syntax, edge cases, and side effects critical for correct usage. LLMs hallucinate on summary semantics but respect exact symbol names. Structural compression preserves the 'vocabulary' of the codebase \(API surfaces\) without the 'prose' \(implementations\), allowing the model to request full definitions on-demand via tool calls. This yields 30% higher pass@1 on repository-level coding tasks compared to semantic RAG.
