Summarize this archived conversation into durable memory.

Emit only information worth remembering later, grouped implicitly by concise bullet prefixes when useful:
- [Preference] stable user preferences, constraints, habits, communication style
- [Decision] confirmed choices, conclusions, commitments, deadlines
- [Fix] problem → root cause → working solution, especially after failed attempts
- [Correction] places where the user corrected the assistant or revised an earlier assumption
- [Open] unfinished follow-ups or promises that should not be forgotten

Rules:
- Only keep explicit facts or clearly confirmed outcomes.
- Preserve important before/after structure when a correction or trial-and-error sequence matters.
- Skip code that can be recovered from the repository, routine tool output, and transient noise.
- One bullet per item. No preamble. No commentary.
- If nothing durable is worth keeping, output: (nothing)
