-- Companies and Orgs: the upper rungs of the deploy ladder (single → team →
-- company → org). The model is recursive — *every tier is a topology whose
-- nodes are the tier below*. A team binds nodes to claws (migration 0010); a
-- company binds nodes to teams; an org binds nodes to companies. Children are
-- resolved from these tables at execution time (cm-topology stays pure — the
-- parent graph never embeds a child graph, only a string id in node.attrs).

-- A company = a baseline TOPOLOGY staffed with real teams. `graph` is the
-- TopologyGraph whose nodes carry attrs["team_id"] = the bound team's uuid
-- (and attrs["agent"] = the same id, so the recursive executor receives it via
-- TurnRequest the same way a team node forwards its claw alias).
