videos: From intent to execution — Claude alone vs Claude through Aomi (EVM + Solana) - #83

deliverables/videos/intent-to-execution/music.mjs:74-76
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Advance recurring events on the original film clock before applying N().

music.mjs states that events are written on the original film clock and moved to the narrated clock. The bass, pluck, hats, and kick loops map only their initial time, then advance by fixed narrated-time beat intervals. When narration anchors stretch a segment, later hits drift from their original positions. In the first hat window, the second hit is at about 13.567s instead of 13.413s, a delay of about 153ms.

Advance a film-clock variable and apply N() to each event onset. This preserves the 112 BPM pulse on the film clock and applies the narration warp.
