Purging history now keeps the original file's permission mode instead of writing a fixed one.

When purging entries from history.jsonl, the rewrite now stats the existing file and reuses its mode for the replacement, instead of always writing with a fixed 438 & ~umask mode.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Confirmed since Anthropic's documentation has since written up history.jsonl, on Explore the .claude directory. | `~/.claude/history.jsonl` | Up-arrow prompt recall, `Ctrl+R` history search, and `!` shell-command completion | claude-directory see the edit
