A named grouping of environments belonging to one owner (003 T006).
defmodule MyApp.Project do
use AshSandbox.ProjectTemplate,
data_layer: AshPostgres.DataLayer,
domain: MyApp.Sandboxes,
repo: MyApp.Repo,
table: "projects"
endSame template shape and the same reason as AshSandbox.RegistryTemplate: a
library-declared resource has its data layer frozen into the beam at library
compile time, so the host must own the declaration (012 research R5).
owner_ref replaces tenant_id
A bare string the library stores and compares but never parses, resolves, or
joins against (012-FR-007). Axonn supplies its tenant id, and declares
the belongs_to to 002's Tenant on its own side — the library has no
tenant concept and must compile without one.
The requirement is unchanged by the substitution: 003-FR-002 requires one
owner's resources be unreachable from another's, which turns on the values
differing, not on what they mean.
