Shortened Vowels

On four lines from al-Baqara and eight lines from Ṭaha I show if and how the KFE and IPak write vowel letters that are spoken short:

In the first two lines (and 5 + 6) ‒ both right and left ‒ yāʾ stands for /ā/ (dark pink),

in the third and fourth line only on the left there is a difference between /fī qulūbihi/ and /fĭ l-arḍi/ for /ī/ there is a ǧazm above yāʾ, for /ĭ/ there is no sign: the yāʾ is ignored.
In line 7 on the left ط  above (4) forces a pause after the verse, so the two con­sonants at the beginning of the next verse do not shorten the /ā/ to /ă/ like the following /ʿală l-ʿarši/ as can be seen left and right: no small alif either side ((BTW left the short alif is a long vowel sign = turned fatḥa; on the right it would be con­verting sign = convert yāʾ to alif)).

In lines (7+) 8/ fī/ is shortened to /fĭ/ on the left (no ǧazm sign above yāʾ), on the right readers are supposed to know.

In line 9 (right 9 to 10) we see a difference: the KFE shortens the yāʾ/alif maq­ṣūra because two consonnant letters follow, IPak (on the left) has an obligatory pause (as shown by the hamza <no waṣl> on /allāh/), hence no shortening: a straight fatḥa just as twice in line 10 (lines 10 + 11 on the right).

The last three cases are fine on both sides. The /ī/s are long, because there are madda signs above, the /ă/ is short because there is no small alif (neither a con­verting sign on the right, nor a turned fatḥa on the left).
