"""Every cross-entity id field on a backend model: what entity it points at, and where that
entity is resolved from an id.

OpenSwarm stores entities as JSON records that point at each other with bare strings. A workflow
holds `edit_agent_session_id`, an app record holds `workspace_id`, a dashboard card holds
`session_id`. Nothing at the type level says the referent exists, so a reader that forgets the miss
renders a blank instead of a designed empty state. This module is the one place that says what each
pointer means, and the `dangling-refs` linter check (linter/checks/dangling_refs.py) fails any new
`*_id` / `*_ids` field on a backend model that is not declared here.

Data only, no logic: nothing resolves a pointer for you. The `EntityStore` rows name the function
that does, and the linter checks those names still exist so a rename can't quietly rot this file.
