Optional ReadonlybalanceOptional ReadonlyfaderReadonlyidOptional ReadonlymodeOptional ReadonlymonitorWhether monitor DIM was engaged (#191). Absent reads as off.
Optional ReadonlymonitorMonitor LEVEL (0..1) — the cue-bus master fader (#191). Restores the operator's monitor loudness. Absent reads as unity.
Optional ReadonlymonitorOptional ReadonlymonitorWhether the monitor destination was in mode B (takeover-from-MAIN-on-solo); absent = mode A.
Optional ReadonlymuteOptional ReadonlynameOptional ReadonlysipWhether the destructive SIP mode was UNLOCKED in Setup (#192). Absent reads as DISARMED, so a reload never silently re-arms the house-muting mode.
The cue bus's persisted state (cue/solo-to-monitor spec) — fader/mute/balance mirror MatrixSnapshotJson's shape; mode + monitorOutput are console-wide but stored here (there is exactly one cue bus, so this is the natural home rather than a second top-level snapshot section).
