+# Gitea compatibility patch
+
+This branch is based on `actions/upload-artifact` v4.6.2 at
+`ea165f8d65b6e75b540449e92b4886f43607fa02`.
+
+Gitea implements the v4 artifact results service, but upstream
+`@actions/artifact` classifies every non-GitHub host as unsupported GHES before
+contacting that service. The compiled upload and merge entry points therefore
+override `isGhes()` to return `false`.
+
+This is the same narrow compatibility strategy documented by Gitea and used by
+`christopherhx/gitea-upload-artifact@v4`. No upload, archive, retention, digest,
+or transport logic is changed.
