6.1.105
दीर्घाज्जसि च
Operational rule vidhi
When दीर्घस्वर is followed by either the जस्-प्रत्यय, or a प्रत्यय of प्रथमा or द्वितीया विभक्ति that begins with a letter of इच्-प्रत्याहार, then the पूर्वसवर्णदीर्घ mandated by 'प्रथमयोः पूर्वसवर्णः' does not happen.

जसि च
Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.
Commentary
The substitution of a long vowel homogenous with the first, does not take place when a long vowel is followed by a nominative or accusative case-affix beginning with a vowel (other than अ) or by the Nominative Plural affix अस्।
Thus कुमार्यौ, कुमार्यः, ब्रह्मबन्ध्वौ, ब्रह्मबन्ध्वः ॥
