ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This targeted fix changes production markdown-link path resolution, including Windows and UNC handling. An unresolved review comment identifies that Windows drive roots can be dropped during base normalization, producing an incorrect host path. You can add or adjust custom eligibility rules.

[
#16354] Explicit Markdown links now collapse relative..segments before the workspace check. The tests cover outside-workspace, in-workspace, position suffix, base-directory, drive, and UNC cases. The inline-code requirement remains unmet.resolveInlineCodeFileLinkMetaandthreadFindTextpasscollapseRelative: false, and the web test expects../b/notes.mdto remain/repo/docs/a/../b/notes.md. An inline-code sibling path can therefore remain classified as a workspace-relative path and be rejected instead of opening read-only as a host file.Resolution

Add tests for an inline-code file outside the workspace and an inline-code file that remains inside the workspace.

Keep Windows roots during base-directory normalization.
For baseDir = "C:\\work\\..\\..\\docs" and a link to sub/../b.md, this loop pops C:. The resolver returns \docs\b.md instead of C:\docs\b.md. The later root-depth check does not run because the link's .. cancels sub. Keep the drive root, or the server and share of a UNC root, when normalizing baseDir.

A relative markdown link such as ../other/notes.md was joined onto the workspace root with its .. left in place, so the workspace-membership check treated it as the workspace path ../other/notes.md and the server rejected it. Apply leading .. segments lexically to the base directory's trailing segments before the check, falling back to the old join when the link would climb to a filesystem root. The base directory's own . and .. segments are normalized first. Inline code in a rendered file, and the same spans in find-in-thread, keep that plain join, so an explicit ../ span stays uncollapsed beside the file. Explicit markdown links still collapse.

Change
resolveMarkdownFileLinkTargetstill applies..lexically throughclimbRelativePathfor an explicit markdown link, then keeps the:linesuffix.../other/notes.mdin/home/me/projectbecomes/home/me/other/notes.md, so workspace membership is null and the file opens as a host path. In-workspace links such asdocs/guide/../readme.mdstay workspace files. The helper still returns null, and the plain join is kept, when the link has no.., starts with~/, or would climb to a filesystem root.Inline code in a rendered file does not collapse.
resolveInlineCodeFileLinkMetapassescollapseRelative: false, so a sibling../or./span stays the joined path beside that file. Find-in-thread does the same: markdown link hrefs collapse, inline code spans do not.Why
Fixes #16354
A link like
[notes.md](../other/notes.md)in/home/me/projectresolved to/home/me/project/../other/notes.md.workspaceRelativeFilePathonly checks the string prefix, so it treated the target as the workspace path../other/notes.md, which the server rejects. Clicking the link failed instead of opening the sibling file read-only, and the tooltip showed the uncollapsed path. As the maintainer triage asked, the collapse is lexical (norealpath), applies only to the path part, keeps any line/column suffix, and keeps in-workspace links likedocs/guide/../readme.mdas workspace files.This supersedes #16754 (it normalized inside the shared
resolvePathLinkTargetand collapsed forward-slash UNC paths) and #16770 (correct, but it added about 113 lines of root-type parsing). This version only handles relative links and never recognizes root types.Verification
