14001400* `post_tokens`: Approximate token count after compaction
14011401* `error`: Error message when compaction failed
1402* `precompute_reuse`: Only set when `trigger` is `"manual"` or for an [idle compaction](https://code.claude.com/docs/en/settings-reference.md#idlecompaction), which reports `trigger` as `"auto"`. Auto-compaction can prepare a summary in the background before the context window fills, and this attribute records whether the compaction reused that prepared summary. `"hit"` means it was reused; `"miss_custom_instructions"`, `"miss_hook"`, and `"miss_not_ready"` give the reason a fresh summary was computed instead
