Which channel is not mapped in the data?

The main idea here is identifying which channel has no mapping by looking for what’s missing in the mapping data. A channel isn’t mapped when there isn’t an entry for it in the mapping registry. To find the unmapped channel, compare the list of channels that should have mappings with the channels that actually have entries. The one that doesn’t appear in the mapping data is the channel that isn’t mapped. This matters because any process that relies on the mapping will not have a defined route or label for that channel and you’d need to decide how to handle it—flag it, skip it, or supply a default.
