Fix the journey wedge; 4-bar instrument hold; bass -25% global

Paul's ride (blues -> tango -> neoclassical): half a measure of guitar, silence, then the whole song stops. Three interlocking causes, all fixed:

• 1. THE WEDGE: any throw inside injectChord (a voice module failing to instantiate under load, a bad param time) escaped before nextTime/serial advanced

• 2. THE HALF-MEASURE GUITAR: continuous blend weights re-pick the dominant genre every bar, so the flip queue swapped the sampler lead in and out within a measure

• 3. BASS_TRIM=0.75 at the single bass-level realization point (Paul: "lower the bass 25% everywhere") — all 63 genres, press + live, relative balances preserved.

Verified: the exact ride passes (0 errors, never silent, tango's nylon/bandoneon lead full sections, flip minGap 4 bars); hold + wedge + macro + live smokes all PASS.
