The supplied research records unresolved findings for every lead actor's credit, source role, portrayal, performer facts, and comparison, so no confirmed cross-sex casting or established-character changes exist to trigger any rubric floor. Progressive elements remain limited to incidental comedic devices such as a nude-calendar subplot and one episode's use of a transgender character for traditional sitcom misunderstanding rather than normalization or systemic critique. These do not drive premise, arcs, or themes.

The original summary's observation of standard workplace farce is preserved because unresolved casting data cannot be treated as confirmed departures. Material uncertainty is explicit: partial coverage, lack of exhaustive supporting-role verification, and absence of citation-backed confirmation leave open the possibility of unexamined elements, yet nothing supplied alters the non-central status of any social commentary. The work therefore retains a low score under the rubric's emphasis on centrality and intensity. Casting evidence: Casting research is incomplete or contains unresolved comparisons; overall casting fidelity has not been established.

The casting comparison for Chris O'Dowd as Roy Trenneman remains unresolved. The casting comparison for Richard Ayoade as Maurice Moss remains unresolved. The casting comparison for Katherine Parkinson as Jen Barber remains unresolved.
