I actually just wrote something to give me very similar information since I
realised that my basic "this is a ligature" flag wasn't enough data, so each

and the reading direction of the glyph, allow me to work out which characters
formed the glyph.
Correct. That's pretty much the only way to do it.
Don't forget the added complication that there may be multiple glyphs
with the same cluster value. E.g. given the text
<U+0915, U+094D, U+0915, U+093F, U+0915>
you're very likely to get two glyphs with cluster index zero, as in
something like
[imatra=0 | kka=0 | ka=4]
but it's not at all clear from this how you'd determine which characters
formed each glyph.
