- `C:/Users/zhang/.cargo/git/checkouts/Ely-GPUI-Components-5e6462e92cefd62d/58227cd/src/documents/document/lists.rs:110` — C14.9-r3 finding 2 is only partly fixed: outdent handles a leading Tab separately but still counts only spaces when spaces precede a Tab. Open `"- a\n  \t- b\n"` in Visual, open its list block, place the caret after `b`, and press Shift+Tab. The four-column indent becomes a Tab: actual `"- a\n\t- b\n"`, expected `"- a\n- b\n"`; the item remains nested. Both the GPUI interaction and the exact helper reproduce this on native Windows and WSL Linux, while the existing leading-Tab regression passes. Remove one indentation level by columns across mixed spaces and Tabs, update the selection accordingly, and add mixed-whitespace regressions. Evidence: `.work/C14.R-r1/windows-probes.log`, WSL `.work/C14.R-r1/linux-probes.log`, and `.work/C14.R-r1/review.rs.source.log`.
