Hugo version: hugo v0.161.1+extended+withdeploy linux/amd64

Description:

When a Hugo module's go.mod is located in a subdirectory of its git repository (rather than at the repo root), Page.GitInfo returns nil for all content from that module, even though the blobless clone created by the 0.157.0 fix (dfece5b) contains the correct git history.

Reproduction:

Repository structure:

henge/                          ← git repo root
  site/
    go.mod                      ← module: codeberg.org/hereticles/site
    content/
      endeavours/
        henge.md                ← content file

Module imported in consuming site:

toml

[[module.imports]]
  path = "codeberg.org/hereticles/henge/site"
  [[module.imports.mounts]]
    source = "content"
    target = "content"

What happens:

Hugo creates the blobless clone correctly at ~/.cache/hugo_cache/modules/filecache/modulegitinfo/repo_<hash>/. Running git from within that clone confirms the history is present:

bash

git log -1 --format=%H -- site/content/endeavours/henge.md
# returns: daa0b2c43548c16f9fdde191e66b0269f9715293

However Page.GitInfo is nil. Adding a debug line:

go

{{ warnf "File path: %q" .Page.File.Filename }}

Shows:

WARN  File path for "endeavours/henge.md": "/home/shri/.cache/hugo_cache/modules/filecache/modules/pkg/mod/codeberg.org/hereticles/henge/[email protected]/content/endeavours/henge.md"

Root cause:

The blobless clone maps the file as site/content/endeavours/henge.md (relative to the git repo root), but Hugo is looking up content/endeavours/henge.md (relative to the module root). The offset between the module root (site/) and the git repo root is not accounted for.

Workaround:

Move go.mod to the git repo root. The module path no longer includes the subdirectory, so the cache path strips correctly and the repo-relative path matches the blobless clone.

Expected behaviour:

Page.GitInfo should populate correctly regardless of where go.mod is located within the git repo. The path translation should account for the offset between the module root and the git repo root.
