Git bundle uploads now fall back to a squashed snapshot when the repo uses partial or promisor clones
When creating a git bundle fails on a repository that isn't hardened and wasn't deliberately aborted, Claude Code now checks the repo's git config for signs it's a partial or promisor clone (settings like extensions.partialclone, a remote.*.partialclonefilter, or a remote.*.promisor entry). If any of these are present, it automatically retries, forcing the operation into a "squashed" mode that bundles a snapshot of the working tree instead, and marks the result as a promisor fallback.
Partial and promisor clones don't have all the git objects needed to build a normal bundle, which used to just fail. Now Claude Code recovers automatically by bundling a snapshot instead, so the upload still succeeds.
