Closes the half of 04-ISSUES/026 that would otherwise come back. The fourteen mounts across the forge, the mail system, the store and the object store are all declared now — but nothing said they had to be, so they were right by coincidence and the next volume added would not be. A bind mount whose source does not exist is created by the container runtime, as root, with a mode it picks. So `owner` and `mode` — which exist precisely so a module can say who its data belongs to — were silently not applied to the only directories holding data. And the rule written for exactly this case did not reach them. A directory the mesh declared and no longer wants is kept, not removed, when it holds anything the mesh did not put there (ADR 0030). That is the answer to *what happens to my data when a module goes away*, and it is written in terms of declared directories: an undeclared one sits outside it, because the mesh does not know it is there. Refused where it is written rather than on the machine, which cannot tell the difference — by the time the host sees the mount it is being asked to make a directory, which it is perfectly able to do. The fault is in the manifest, so it is named at the manifest. Same argument as the action refusal directly above it. A path under a declared directory counts as declared, as do the files a module already names: its own secrets, its grants, what it receives. Every real manifest is checked to still parse, and the refusal bites.
