 Comment and summary text is committed only by **`:w`** or **`:diff.review.save`**, which saves the entire review, including hidden drafts. Dismissing an editor discards its unsaved text; switching between review editors can retain hidden drafts but does not save them. File checkmarks, verdicts, deletions, and manual resolution changes commit immediately to local SQLite without committing draft text. `:diff.review.save path` or `:w path` additionally exports JSON; later metadata autosaves still go to SQLite and leave that export unchanged. Imports create a new stored review identity rather than overwriting another review.
 
+`:diff.review.copy` copies the same text as `vamp --review show ID --all`: repository, summary, verdict, counts, and every saved comment with its anchor and exact excerpt. Resolved and stale comments are included, across all files in the selected review. `clipboard_mode` chooses the system clipboard or Separate-mode internal register. Copying does not save or include unsaved comment/summary drafts. No comments or a clipboard write failure reports an error without replacing the register.

 From the shell, use `vamp --review delete REVIEW_ID COMMENT_ID [--repo PATH] [--json]` to delete a stored comment immediately without opening the editor. Find IDs with `vamp --review list` and `vamp --review show REVIEW_ID --all`. The repository defaults to the current checkout. Both resolved and unresolved comments can be deleted; the review and any JSON exports remain intact. An editor holding the old review revision must reload before saving.
 
 Storage defaults to `$XDG_DATA_HOME/vamp/reviews/reviews.sqlite3`, or `~/.local/share/vamp/reviews/reviews.sqlite3` when XDG_DATA_HOME is unset or relative. Configure `review_directory` to override its directory; relative configuration paths resolve against the config file. Repository identity is the canonical checkout root. Each review has a persistent database ID independent of comparison revisions, so reopening changed revisions retains stale comments. Opening a comparison automatically restores the repository's sole review. Multiple reviews open a floating selector: move to an entry and press Enter, or use `:diff.review.open id`. Use `:diff.review.new` for another independent review.
