Rishi: Yājñavalkya-tradition (White Yajurveda Adhvaryu lineage; specific ṛṣi ascription not explicit in the mantra itself).
Devata: Agni (with Āpas as attendant purifiers); second hemistich functions as a ‘dhruva’/stability formula rather than a single-personal deity address.
Chandas: Mixed/prose-yajus (Yajurvedic formulaic style; not a strict ṛgvedic metre).
