The adhikāra sūtra governing sandhi rules is "saṃhitāyām", "when there is conjunction".  So when there is not conjunction, no sandhi rule is triggered.

In the Mahābhāṣya, Patañjali does have a discussion about how slowly you can speak and still be considered to be producing a vākya.  This problem can be related to the issue of what counts as conjunction.

Best,

In other words, the use of sandhi is a convention, so the question might be slightly rephrased as: what are the conventions of the poets, and of the scribes. No?
(Perhaps, as is quite likely, of course, this was implied in the question, and I should have kept my ideas to myself.

Correction: I meant ‘at the end of one line’.

> I’ve just had a quick look at an edition of the Saundaryalaharī, in Śikhariṇī (17 syllables to a line), and sandhi is broken only between half verses and whole verses. For example, there's a ś  at the end of one half-line followed by a c at the beginning of the next.
