The repo is broken. The merge went wrong, the history is a mess, and no one can push without hitting conflicts. You need a clean slate across the entire environment, and you need it now. That’s where git reset with environment‑wide uniform access becomes the decisive move.
A git reset isn’t just about rolling back local changes. When managed properly in a uniform access context, it clears and aligns all workstations, CI pipelines, and staging branches to the same commit baseline. This prevents ghost changes, stale branches, and divergent histories from poisoning future work.
To execute this safely, first identify the target commit hash — often HEAD of the main branch checked from the authoritative remote. Then run:
git fetch --all
git reset --hard <commit-hash>
git clean -fd
On its own, this affects only your local environment. Achieving environment-wide uniform access requires enforcing the same state across every developer machine and build environment. Git server hooks or admin scripts can push the reset to all remotes, forcing fast‑forward or hard‑reset alignment.
