Rishi: Traditional: connected with Aśvamedha liturgy; often transmitted under Yājñavalkya-lineage in Śukla tradition (specific ṛṣi not explicit in the given excerpt)
Devata: Devatā-complex: the officiants as functional powers of Yajña; ultimately Prajāpati/Yajña as the encompassing deity
Chandas: Mixed/Anuṣṭubh-like cadence in transmission; exact chandas requires full pada-count verification
