/p t s~tʃ k ʔ/ <p t c k ʼ>
/b d z~dʒ/ <b d z>
/f s̺ x h/ <f s x h>
/m n ŋ/ <m n ŋ>
/β r j ɣ gʟ/ <v r y g l>
/a ɛ ɔ ɪ ʊ i u/ <a e o ë ö i u>

Preinitials: p- t- c- k- ʔ- f- s- x- h- m- n- v- y-.
Finals: ʔ s c z h m n ŋ v r ɣ

Preinitial mergers:
t-s > ts
p- t- c- k- > ʔ- / _C UNLESS _A — the plosive preinitials debuccalize everywhere but before /v r y g l/
p- t- c- k- > ʈ / _r  — this probably occurred at the same time as the other retroflex-creating shifts
h$ > h- — syllable-final h becomes aspiration
f- x- > h- / _C UNLESS _A
s(-)v s(-)r s(-)y s(-)g s(-)l > f ʂ ɕ x ɬ
m- > n-
T-y > TS, y- > 0

Retroflexes and alveolar affricates:
o > ö / br_
ʔ-br ʔ-dr ʔ-r > ʔ-ʈ (the glottal preinitial devoices following plosives)
br dr > ɖ
t d > ts dz / _{i ë e y}

Final palatal loss: (added)
ac az > əʔ ər
ec ez > əʔ ər
c z > ʔ r / _#

More schwa, -v loss:
eɣ aɣ > əɣ ɒɣ
av ov > ɒ ʊ
v > ɣ / _#

Vowel changes and gamma loss:
i u > ë ö / _r
ë e > yö yə / #_ng (added)
ë e > ö ə / _ng (added)
x ɣ > c z / _i
va > vɒ
ɣ > v / $_{a e o ö u}
ɣ > y / $_
gʟ > g
a > o / my_
(n > ȵ  / _i sometimes)

High vowel frication:
i u > ɿ ʮ
ë ö > i u
x c r z > t t d d / _ɿ
t d > ts dz / _ɿ
x r > k d / _ʮ
vu > ʮ

Palatals form:
t d n s > tɕ dʑ ȵ ɕ / _{e i y} — but isn't palatalization of velars more common? maybe I'll do that instead
my > ȵ
y > 0 / C[palatal]_ C[labial]_ — not sure if I want to keep this

Tonogenesis:
s-tɕ s-dʑ s-ʈ s-ɖ s-s s-ʂ s-ɕ s-ɬ s-l > ɕ ʑ ʂ r s ʂ ɕ ɬ ɬ
s- > h-
Default tone is 3.
h- ʔ- > 35 2
c z > ʔ r / _$
ʔ$35 ʔ$3 ʔ$2 R$35 R$3 R$2 > 5 5 3 42 31 31 — tone inventory: 31 2 3 5 35 42
s x > ɕ / _i
x > f / _u
x > h

Stop voicing loss:
P[voice] > P[-voice]V[breathy]
31 2 3 5 35 42 > 5 2 2 42 42 31 / V[breathy]_ (here be dragons)
n-P > P[voice]
n-f n-v n-s n-ʂ n-ɕ n-{ɬ l} n-x > b b dz ɖ dʑ n g

More schwa, part 2:
e i > ə ɿ / s_ (this happened earlier, probably)
ɬ > s

No nasal+fricated vowel sequences:
m n ȵ > mb nd ndʑ / ʮ_
m n ȵ > mb ndz ndʑ / ɿ_
(but nasal + nasal fricated vowel sequences turn to syllabic nasals)

35 42 > 5 31
