on Aug 24, 2026 Fork promotion for this issue could not complete: the promotion helper attempted to squash-merge the completed fork PR (
a0x1ab/azure-cli) into its temporary base branch, but that base branch (agent-assist/azure-azure-cli-issue-33965-ae51706ce7aa) no longer exists on the fork even though the fork PR shows as merged/closed. This looks like a partially-completed prior promotion attempt (squash merge succeeded and the temp branch was cleaned up, but the upstream draft PR was never opened). A maintainer needs to inspecta0x1ab/azure-cliPR #4 and either recreate the temp base branch from its merge commit or restart the fork task for this issue.Fork promotion is blocked: the fork PR's temporary base branch (
agent-assist/azure-azure-cli-issue-33965-ae51706ce7aaina0x1ab/azure-cli) no longer exists (it was deleted after the fork PR was merged), so the squash/promotion step cannot read the merged commit. A maintainer must repair the Agent Assist dispatch record (e.g. recreate the temp base branch at the pre-merge SHA, or restart the fork task) before this can be promoted to an upstream draft PR.Fork promotion is blocked: the fork PR (
a0x1ab/azure-cli#4) is already merged, but its temporary base branchagent-assist/azure-azure-cli-issue-33965-ae51706ce7aaand head branchcopilot/fix-azure-cli-bug-33965no longer exist in the fork (likely deleted by an auto-delete-branch-on-merge setting ona0x1ab/azure-cli). Promotion needs a live branch ref to squash and open the upstream draft, and cannot proceed from a merge commit SHA alone under the current pipeline. The merge commit is still reachable atd33c845636ff04eb0b0b870215f187e213edb77a. A maintainer should either disable auto-delete-branch-on-merge on the fork repo, or recreate the two branches pointing at that commit, so the Agent Assist dispatch record can be repaired and promotion retried.
