This is the PREFIX of a turn that was too large to keep. The SUFFIX (recent work) is retained.

Summarize the prefix to provide context for the retained suffix:

## Original Request

[What did the user ask for in this turn?]

## Early Progress
- [Key decisions and work done in the prefix]

## Context for Suffix
- [Information needed to understand the retained recent work]

Output only the structured summary. No extra text.

Be concise. Preserve exact file paths, function names, error messages, and relevant tool outputs or command results if they appear. Focus on what's needed to understand the kept suffix.
