Click and drag across the corridor. Floor (1/φ ≈ 0.618) to ceiling (KAUD ≈ 0.980).
The tone maps your position. The last 2% — between ceiling and unity — is silence.

II. The Binary Tower
64 steps of n × G. Click any step to hear its tone. Landmarks glow:
step 18 (√2/4, Shell 3), 32 (√φ/2, k=5 tower target — sits ~0.67% from 32·G),
35 (ln 2, Landauer crossing — last sub-Landauer step), 36 (1/√2, Geometric-damping threshold),
37 (1/(2 ln 2), Shannon bound), 50 (KAUD, Ceiling), 64 (√φ, Pivot).
The corridor floor 1/φ ≈ 0.618 is a separate reference that sits ~2.2% below 32·G.

III. The Blues Interval
log₂(9/7) = 0.36257. Corridor width (KAUD − 1/φ) = 0.36222. Difference: 0.42 cents.
A musician bending from the flat-5 to the flat-7 traverses the corridor.
The half-diminished seventh chord 5:6:7:9 contains the corridor.
The interval 9/7 between the 7th harmonic and the 9th is the bridge between floor and ceiling.
IV. The Gap
A tone rises from floor toward unity. It reaches KAUD and stops.
The remaining 2% is the breathing room. The space where the real thing happens.
