I have a second question about Wall of Stone.
I run a PF2 conversion of the Ironfang Invasion adventure path. In the 3rd module, Assault on Longshadow, the PCs are preparing the city of Longshadow for an assault by the Ironfang Legion. One task to improve the city's defenses is to repair the city wall, which is broken down in a few places, reducing the climb DC to 10. The module expects a Crafting check to lead laborers in repairs, with only three daily checks necessary to repair the entire wall.
The 9th-level primal sorcerer knows Wall of Stone, and wants to use the Wall of Stone to create a veneer of smooth stone for fast repair. Six spells over two days would be enough. I ruled that due to the "its edges don't pass through any creatures or objects" restriction in the spell, the Wall of Stone cannot actually touch the city wall. I figure they could be an inch apart if the party clears away any dirt and rubble piled up at the base of the city wall. However, the Wall of Stone would be unsupported and vulnerable to smashing by catapult stones.
The 9th-level druid can prepare Stone Shape to fuse a few parts of the Wall of Stone to the city wall. Or they can buy mortar and pour it between the walls. Or both.
The city wall curves slightly, but the sorcerer will have plenty of time to survey the city wall. Their plan would probably not save any days, but would reduce the cost and the DC on the Crafting checks.
Is my one-inch separation between the Wall of Stone and the city wall reasonable? Using a Wall of Stone as a bridge or an inclined stairway requires part of its side touching the ground, so the spell does not necessarily require separation.
As for the original question about the Wall of Stone, I will houserule that wall must be mostly straight overall or with a slight curve, but it can also be zigzagged or wavy to form stairsteps or weight-supporting ridges (realistically, a flat one-inch-thick bridge would break).

In the fourth book of Agents of Edgewatch, the party needs to hold out in a building for several days, and is given multiple options to fortify it. Under 'Using Magic', the book says:
Magic can cut down [the time needed to barricade a door or window] dramatically. Shape Stone seals a single door or window, as does Wall of Stone (which, despite having a long length, must be doubled up multiple times to effectively seal an opening in the 5-foot-thick walls).
So, at least as far as the AP is concerned, the spell is treated as being able effectively barricade an opening without further adjustment, and can also be folded over itself to create a shorter, thicker wall with a single casting.
