What

When the primary, hardened method of capturing a git bundle for a device-bound session fails specifically with an unsupported_layout error, Claude Code now retries using a legacy capture method instead of simply failing. The retry pins the index file so it can't change mid-upload.

Why

This makes bundle uploads more resilient on repository layouts the primary hardened path doesn't support, so cloud/teleport sessions can still be seeded instead of failing outright.
