v0.6.3

Fixed

• Open centring vowels were over-segmented. Several open (coda-less)
  vowel frames split into spurious extra syllables; they now parse as a
  single syllable across every scheme:
  • เ◌ือ carrying a tone mark — เสื้อ, เนื้อ, เชื่อ,
    เมื่อ, เบื่อ — now one /ɯːa/ syllable (tlc seuua{F} and
    so on) rather than three.
  • เ◌อะ short /ɤ/ — เลอะ, เถอะ, เยอะ — now one syllable.
  • เ◌ียว after a leading ห — เหลียว, เหนียว, เหมียว —
    now one syllable (liaao etc.).
  • A preposed เ written before a leading consonant but belonging to a
    เ◌ือ frame on the next consonant — เสมือน → sa-meuuan
    (leader ส plus the centring syllable), not three syllables.
• Three bare consonants now read as a leader plus a closed syllable. A
  C₁C₂C₃ sequence with no written vowel — ถนน, ขนม, กมล —
  parses as a leading consonant (C₁ with inherent /a/) plus a closed
  C₂C₃ syllable (C₂ onset, inherent /o/, C₃ coda): ถนน →
  tha-nohn, not tha-na-na.
• Word-final consonant clusters read as a coda. A true cluster
  C + ร ending a word after a vowel-bearing syllable is a coda — the
  first consonant closes the syllable and ร is silent — rather than an
  onset cluster: บัตร → bat, สมัคร → sa-mak, เนตร →
  naeht, วัตร → wat. Words whose C has no preceding vowel
  (e.g. นคร) keep the cluster reading.
• รร is now derived productively. Any C + รร word is read by
  rule rather than only the previously enumerated forms: C + รร plus a
  single final consonant gives /a/ + that coda (มรรค → mak,
  สรรพ → sap); C + รร before another syllable gives /-an/
  (กรรชิด → gan-chit, บรรจุ → ban-joo).

Changed

• morev distinguishes /oː/ from /ɔː/. /ɔː/ /ɔ/ now render as
  ɔ̄/ɔ (Latin small letter open O, U+0254) — the supplementary
  sign introduced in the source dictionary's transcription key
  alongside ə for /ɤ/. Cyrillic о̄/о (U+043E) is now
  reserved for close /oː/ /o/. The previous output collapsed both
  phonemes onto Cyrillic о̄, producing identical Morev strings for
  minimum pairs such as โอน /oːn/ ↔ อ่อน /ɔ̀ːn/ and โต ↔
  ตอ. Examples of changed forms: ขอ → кхɔ̄´ (was
  кхо̄´), บอก → бɔ̄кˆ (was бо̄кˆ), อ่อน → ɔ̄нˆ
  (was о̄нˆ), ฟุตบอล → футˇ-бɔ̄н (was футˇ-бо̄н).
• tlc nucleus spellings for three open vowels, matching the scheme's
  established convention:
  • /uːa/ before a /j/ offglide spells ua (not uaa):
    สวย → suay, ด้วย → duay, กล้วย → gluay.
  • Open short /ɤ/ (เ◌อะ) spells uh: เลอะ → luh — the
    coda-bearing เ◌ิ form still spells eer (เดิน → deern).
  • Open short /o/ (โ◌ะ) spells o (not oh): โต๊ะ →
    dto — closed inherent /o/ still spells oh (นก → nohk).

Notes for callers

• These are accuracy corrections: many words — especially those with open
  centring vowels, leading-consonant (อักษรนำ) syllables, word-final
  clusters, or รร — now produce different, more correct output.
  Callers that snapshot transcriptions should re-baseline.
