Rishi: Traditionally associated with the Br̥haspati/Brahmaṇaspati hymn-complex; specific ṛṣi attribution for VS 3.30 requires the anuvāka metadata.
Devata: Brahmaṇaspati (Br̥haspati).
Chandas: Not determinable with certainty from the single extracted line; likely a Jagatī/Triṣṭubh-family cadence typical of Br̥haspati formulas, but requires full pada-count verification.
