A deep technical breakdown of Claude Code's conversation compaction system — the three-tier architecture, the separate model call for summarization, the nine-section structured prompt, and the in-memory swap mechanics. We cover the trigger conditions, what survives compaction versus what gets lost, the reconstruction phase that re-reads files, and the critical asymmetry: compaction preserves what to do next but systematically drops why we did what we did. Includes token savings benchmarks, power user strategies like CLAUDE.md as persistent storage, and the philosophical question of whether a post-compaction agent is the same agent or a new instance reading a briefing.
