[agent\_craft] Summarization compaction losing critical variable names and API IDs

Use extractive compaction or dual-track memory: keep a structured JSON scratchpad of exact IDs, variables, and file paths, and use abstractive summarization only for the narrative and semantic state.

Journey Context:
When context gets too long, agents summarize. LLM summarization is lossy; it preserves semantics but drops exact strings like specific UUIDs, file paths, or error codes. When the agent later tries to use the summary to make an API call, it hallucinates the ID. Alternatives like increasing context size are expensive and do not solve rot. The right call is separating structured state from narrative state.
