Notes :

It is very likely that some phonemes or graphemes that do not appear explicitly in the associated documentation were nonetheless meant to be included. These would be :
The phoneme /ɛ/, which is not mentioned explicitly but is probably the reason the grapheme <Ê ê> appears in the alphabet.
The phoneme /ø/ or /œ/ is also not mentioned explicitly, and there is no grapheme either, but the presence of a ";" shows that it was probably meant to be included. However, this is only very indirect evidence.
In a similar way, there is reason to believe that the phoneme /ɲ/ is included, and corresponds to the explicitly mentioned grapheme <Ñ ñ> ; meanwhile, the phoneme /ᵑg/ is only evidenced by a ";".
The flap /ɾ/ is indirectly mentioned by its inclusion in the syllable /bɾa/ corresponding to the grapheme <Ƃ ƃ>.
Some IPA symbols used in the original description are most likely to be erroneous :
The phoneme /χ/ is probably what was meant by /ħ/ ;
The notation /ɧ̙ʷ/ is the most recent agreed upon description of a phoneme that probably corresponds to what was described as /h̪/ in the original documentation.

Spelling rules

The so-called "link" is a diacritic that is used with either <i> and another vowel, in order to denote the approximant /j/, or <w> (or more rarely, <o>) and another vowel to denote the approximant /w/. A breve accent is also sometimes used in addition to the link, where it would otherwise be ambiguous. Here are a few examples :

i͠e /je/
o͠a /wa/
ê͠w /ɛw/

i͠i /ji/
i͠ĭ /ij/
w͠w /wu/
w͠w̆ /uw/
w͠o ou o͠o /wo/
o͠w̆ ou o͠ŏ /ɔw/
