The strip's VIRTUAL SOUNDCHECK SOURCE — live (its patched input) or track (its own track
in the loaded take), per channel (2026-07-16-recording-vsc.md §3.1's ChannelSource.mode).
INPUT CHANNELS ONLY. A bus master's source is the sum of the channels, so a soundcheck
replays the INPUTS and re-makes the mix — the row has no instance on MAIN or a bus, which
says "there is nothing here to switch" better than a refusal would.
The per-channel escape §3.2 asks for: engage the soundcheck globally on /vsc and put the
click track or a talkback mic back on live here.
