Function selectionCarriage

selectionCarriage(
    parts: readonly ChannelPart[],
    kind:
        | "input"
        | "fxReturn"
        | "aux"
        | "mix"
        | "matrix"
        | "cue"
        | "main"
        | "fxSend"
        | "dca"
        | "muteGroup"
        | "mixMinus",
    capability: ChannelCapabilityState | undefined,
    contract?: Readonly<Record<ChannelFact, ChannelFactDecl>>,
): readonly PartCarriage[]
How a whole SELECTION fares against one target — composites expanded, in the vocabulary's own order so two clients listing the same paste list it identically.
Parameters
- parts: readonly ChannelPart[]
  what the operator selected, composites included
- kind:
      | "input"
      | "fxReturn"
      | "aux"
      | "mix"
      | "matrix"
      | "cue"
      | "main"
      | "fxSend"
      | "dca"
      | "muteGroup"
      | "mixMinus"
  the target channel's kind
- capability: ChannelCapabilityState | undefined
  the target's live /capability row state, or undefined when the console holds no capability row for it — in which case only the contract's kind column can answer, and it does, rather than the paste guessing that everything is carried
- contract: Readonly<Record<ChannelFact, ChannelFactDecl>> = CHANNEL_CONTRACT
  the table to derive from (defaults to CHANNEL_CONTRACT)
Returns readonly PartCarriage[]
one PartCarriage per atomic part the selection covers
