+| organization | `sharing.organizations` on the form (`@objectstack/spec/ui` `SharingConfigSchema`): a non-empty list of organization slugs the form is published to. The link names one, `/forms/SLUG?organization=ORG_SLUG`; the server reads the organization carrying a listed slug, as the system, and the submission acts in it (the write's `tenantId`: the row lands there and its number sequences count there). |
+| match | the link's `organization` parameter, not a host or a path prefix. A bound form's link naming no organization, or one the form does not list, is answered as an unpublished form (`404 FORM_NOT_FOUND`) on both form doors; an unbound form's link naming one is refused the same way. Nothing falls back to the default organization. |
+| guest grants | unchanged: the form doors keep the form grant (D2 class 1), now resolved under the bound organization. No set is bound to `guest` (D3 item 5). |
+| allowed doors | the two public form doors (D2 class 1) only. The class 4 and 5 endpoint doors keep D4's located refusal on a multi-organization deployment. |
+
+A form that lists no organization keeps D4 exactly. The decision is `resolvePublicFormOrganization`
+(`@objectstack/core`, beside D4's guest-organization refusal); the doors ask it in
+`packages/rest/src/form-routes.ts#registerFormEndpoints`.
