  "message": "project: derive HEAD fallback from git\u0027s own default branch\n\nWhen the default branch cannot be determined dynamically, repo fell back\nto a hardcoded \"refs/heads/master\". This can point at a branch that does\nnot exist on the server, since projects increasingly default to \"main\".\nRather than swap one hardcoded name for another, ask git itself what it\nwould use.\n\nBug: 483758905\nChange-Id: Ic66712acea98f8e548a2d6d8211865ee5c416b4d\nReviewed-on: https://gerrit-review.googlesource.com/c/git-repo/+/612845\nTested-by: Brian Gan \u003cbrgan@google.com\u003e\nReviewed-by: Gavin Mak \u003cgavinmak@google.com\u003e\nCommit-Queue: Brian Gan \u003cbrgan@google.com\u003e\n",
