I guess I'll go ahead and start with some allophony, building off of what AK said:

И, у, э & о front from their central positions to i, y, e and œ before с, ҫ & л.

У, э and о back to  ʊ,  ɤ and  ͻ after ў and х.

You might want to extend this fronting/backing effect to all front and back consonants (i.e. plosives, nasals, and others I excluded) but I thought it would make most sense after these consonants- making most every consonant create an allophone seems a bit overkill.

And some phonotactics:

Initial/Medial: CV, C(л, р, й, ў)V, V, VC, CVC, C(л, р, й, ў)VC

Final: -V, VC, V(м, н, ф, с, ҫ, х, р, л)(п, б, т, ҭ, д, к, қ, г)

Hiatus are allowed, but the first vowel must be higher than the second. Diphthongs can include any vowel + й or ў, except for ий & yў.

Most words have at least one tonal vowel, some have two and very few have three tones.

If a syllable with a falling or circumflexed vowel is inserted after a previously toneless vowel due to a grammatical ending, the toneless vowel becomes rising.

If a syllable with a rising vowel is inserted after a previously rising vowel due to a grammatical ending, the latter becomes toneless. If the latter vowel was circumflexed, it becomes falling.

If a syllable with a toneless vowel is inserted after a rising or circumflexed vowel due to a grammatical ending, the former vowel becomes falling.

Tones within a word cannot modify or be modified by adjacent words.
