Formula card EX_022 — Wind Scene

Game: Chrono Trigger · Composer: Yasunori Mitsuda · Purpose class: EXPLORATION

Tier: RUNG-1 MEASURED · measured 2026-08-07T12:06:10+00:00 · source format mov,mp4,m4a,3gp,3g2,mj2 at 44100 Hz

Length 204.573 s across 20 sections; baseline 83.35 bpm; key A minor.
Opens fade_in; the hook lands at 0.488 s.
Arrangement runs up to 9 spectral lanes; melodic salience 0.738 across 548 extracted notes.
Event grammar: 18 drops, 16 raises, 2 breaks, 0 tutti passages; silence budget 2.1%.
Dynamic range 9.47 dB, peak at 63% through the track.
Complexity steps 5 times across 71 bars, 5 of them at a section boundary.

Lanes are a spectral_band_proxy reading, not an instrument roster. Section 11.1 requires the lane method be declared. Bands are not instruments: two instruments in one octave read as one lane, and one instrument spanning two octaves reads as two. Entry/exit and simultaneity shapes are trustworthy; a roster is not claimed.
Bar arithmetic on this card uses 4 beats per bar at the baseline tempo. The onset period beside it is MEASURED; the signature is not.
A cadence census needs harmonic transcription and is a rung-2 dimension; the seam measurement is what rung 1 can honestly report about how it ends.
Windowed key agreement below ~0.7 is the modulation signal at rung 1; a pivot-chord map needs symbolic transcription (rung 2).
