. . . . "Lists the observer-tier members of a given space (highest validated tier is observer). Reads the materialized tier directly off each validated gen:RoleInstantiation (npa:hasRoleType) in the current space state and excludes anyone holding a higher tier; no role-declaration re-derivation. IRI-keyed by npa:forSpace (param space). Adds a user_label column so each agent is shown by name instead of by bare IRI: the canonical foaf:name mirrored into the current space state (which comes from the agent's own key introduction) when present, otherwise the foaf:name asserted for that agent in the pubinfo of the grant nanopublication. Most role holders of a space have no key introduction of their own, so without the fallback they render as a bare ORCID. Rows are ordered by that display name." . . . "List space observers" . .
