Proof — Verse 1.128

स्वमात्रा परमात्रा वा श्रुत्या प्रक्रम्यते यथा ।
तथैव रूढतामेति तया ह्यर्थो विधीयते ॥ १२८ ॥

Whether as its own measure or as the measure of another — however it is set going by the utterance, just so does it become established; for it is by utterance that the object is determined.

Endorsed axioms (each cite is verbatim commentary)

• {"kind": "relation", "name": "prakramyate", "from": "vak", "to": "artha"}“set going, by the utterance”
• {"kind": "predication", "name": "rudhatameti", "of": "artha"}“attains rudhi, established currency”
• {"kind": "relation", "name": "vidhiyate", "from": "vak", "to": "artha"}“for the object is *ordained* by utterance”
• {"kind": "predication", "name": "characterizes", "of": "matra"}“the contour settles along the lines speech first draws, and repeated saying is what fixes it”

Denials

• {"kind": "predication", "name": "nitya_akara", "of": "artha"}“Objects do not first possess determinate contours which speech then reports”
• {"kind": "relation", "name": "paurvapya", "from": "artha", "to": "vak"}“the contour settles along the lines speech first draws”

Rejected readings (refuted by compiled theorems)

• “Objects possess determinate contours before being reported by speech, which merely describes existing objective realities.” — Directly contradicts the commentary's explicit statement that objects do not pre-exist with determinate form; speech does not report pre-existing contours but creates them through utterance.
• “The utterance merely reflects or passively conveys objects that are independently established through other means.” — Treats vak as a passive mirror rather than the active determinant (vidhiyate) that the verse emphasizes. The verb vidhiyate is explicitly described as 'strong and chosen: the verb of injunction and ordination', making speech the generative principle, not a passive report.
• “The object's essence is determined by whether the utterance uses its own measure or another's measure; different measures yield different objects.” — The verse explicitly uses a disjunctive (vā) to show that measure (own or another's) does not matter to the establishment: 'Whether as its own measure or as the measure of another... just so does it become established.' The establishment (rudhi) follows regardless of which measure is adopted.
