RECORD:
  constraint_type      = cannot be omitted               -- p.vol_II_p027

ASSERTIONS:
  - [structural] The omission of a samvadi of the amsa is not accepted in jāti transformations
    -- p.vol_II_p026 "Şādja-madhyamā does not become ṣāḍava on niṣāda being amsaand also on gandhara (being amsa), because the omission of a samvadi of the amsa is not accepted."
  - [relation] The samvādī of the aṁśa cannot be omitted in forming ṣāḍava variations
    -- p.vol_II_p027 "because of the negation of the omission of the samvādī of the aṁśa"
  - [relation] The non-omission of the samvādī (consonant note) prevents certain jātī forms from being ṣāḍava
    -- p.vol_II_p029 "because of the non-omission of the samvādī (of the amsa); similarly it is not desired to be so when gandhara (is the amsa)."
  - [relation] Seven specific aṁśas are devoid of ṣāḍava-forming capacity due to samvādī non-omission
    -- p.vol_II_p029 "These seven (amśas) are devoid of the state of making six svara forms."
