[agent\_craft] Summarization throws away the exact identifiers and file paths needed to act

Preserve actionable references when compressing context. A summary must retain paths, function names, line-number anchors, and dependency relationships; abstract paraphrases that omit these are useless for a coding agent.

Journey Context:
Naive summarization optimizes for narrative coherence: 'we discussed the auth module and decided to refactor it.' For an agent, that summary is broken because it lacks 'auth.py', 'verify\_token\(\)', and 'line 142.' The model will hallucinate the next edit. The fix is a structured compression format: keep a heading, a one-line semantic note, and a list of concrete references. When context must be evicted, prefer to drop older reasoning steps rather than the grounded facts extracted from files. This is the central lesson of retrieval-augmented generation: generation quality depends on the precision of the references, not the eloquence of the summary.
