Formula card EX_055 — The Cyber Grind

Game: Ultrakill · Composer: Meganeko · Purpose class: BATTLE

Tier: RUNG-1 MEASURED · measured 2026-08-06T13:25:25+00:00 · source format flac at 44100 Hz

Length 270.316 s across 16 sections; baseline 95.7 bpm; key G minor.
Opens ostinato_first; the hook lands at 0.209 s.
Arrangement runs up to 9 spectral lanes; melodic salience 0.4939 across 130 extracted notes.
Event grammar: 8 drops, 8 raises, 1 breaks, 68 tutti passages; silence budget 0.9%.
Dynamic range 8.19 dB, peak at 27% through the track.
Complexity steps 3 times across 107 bars, 1 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).
