Report #79316

[agent\_craft] Agent summarizes error logs or code and loses the exact variable names, line numbers, or stack traces needed for the fix

When compacting context, use a two-tier approach: extract exact literals \(IDs, line numbers, error codes, variable names\) into a structured Key Facts JSON block, then summarize the narrative around them.

Journey Context:
LLM summarization naturally abstracts away specifics into generalities. If an agent summarizes 'FileNotFoundError for /var/log/app.log at line 42' into 'The app had a file error', the fix becomes impossible. Standard summarization destroys the exact strings needed for search-and-replace or tool execution. Preserving exact literals in a structured format alongside the semantic summary ensures the agent retains both the what and the where.
