  "purpose": "Analysis-only session: model listening as one lens beside signal measurements and text analysis. Reviewers blind to owner ranking. One POST per spec; unknown outcomes are never repeated.",
  "hypotheses": [
    "H1 English attacks/releases words with consonant endings and clipped function words; Ukrainian sustains open vowels on content words (measured: 77% vowel-final phrase endings vs 8%).",
    "H2 English stretches unimportant lead-in words (By, The, That) as pickups and clips content words; Ukrainian stretches content words (забирала, Наступного, Глянула).",
    "H3 Ukrainian information density is highest where English is sparsest (care/coda blocks).",
    "H4 English phrases float off the beat grid more (speech rhythm); Ukrainian sits on the grid."
