[agent\_craft] Rolling summarization of conversation history causes agent to lose exact variable names, API endpoints, or error codes

Implement a dual-memory system: a rolling narrative summary for semantic continuity, and a structured scratchpad \(JSON or YAML\) for exact key-value pairs \(e.g., file paths, IDs, error codes\) that bypasses summarization.

Journey Context:
LLMs naturally compress semantic meaning during summarization, which is great for understanding what happened but fatal for exact state tracking. Agents then hallucinate file paths or API IDs. Alternatives include increasing context window \(expensive, doesn't scale\) or vector DB retrieval \(lossy for exact strings\). The structured scratchpad ensures exact fidelity for operational parameters while the narrative handles the why.
