Inline blame is enabled by default in ordinary live file buffers. The primary caret's line shows its author, commit summary, and short commit ID after the document text; changed or newly inserted tracked-file lines show **Uncommitted**, including unsaved edits. Git-backed jj repositories use the working-copy revision's single parent, not a potentially stale Git HEAD. Merge working copies with multiple parents omit attribution.
Loading happens in the background without network access or changing repository refs/checkouts. Missing, untracked, unborn, and non-repository files have no indicator; immutable historical buffers and comparison views do not receive live-file attribution. Moving, editing, switching views, or disabling clears stale results. The indicator is hidden when the caret is offscreen or the full label cannot fit; wrapped lines use their final visible continuation without covering text, selections, or the caret. Popups retain their normal layering.
Loading happens in the background without network access or changing repository refs/checkouts. Attribution is loaded once for the active buffer's in-memory contents; navigation then selects cached lines immediately, and movement during a cold load does not restart it. Editing, saving, reloading, changing source buffers, regaining terminal focus, or toggling blame invalidates the cached attribution. Missing, untracked, unborn, and non-repository files have no indicator; immutable historical buffers and comparison views do not receive live-file attribution.

Use `:git_blame.toggle`, the palette action, or remappable `config.core.git_blame.toggle`; there is no default keybinding. Set `config.git_blame = false` to disable it at startup. Disabling stops the worker and clears the label without changing text or undo history.
