The support lead at Harbor Booking needs an auditable rollback of a shared routing change. Preserve the faulty delivery in history, restore the baseline route with a new commit and deliver a recorded, published recovery.
Repair a shared route without deleting its original commit. First retain a history reference and a readable comparison. Revert the bad change, commit a short incident record, then publish and tag the repaired snapshot. A reset can make the local file look correct while removing the shared delivery history, which would leave teammates with a different branch story. The checks preserve the original commit and require the inverse repair. Continue from the same repository at every step. The final tag belongs to the repaired published state, and the original route baseline must still be visible.
