Type Alias Channel

External ID shared across users (e.g., Google calendar ID)

Display name shown in the UI

Whether this channel should be selected by default when the user first adds the connection. Tri-state:

• true — pre-select it (e.g. the user's own/primary calendar).
• false — exclude it from the default selection (low-value or irrelevant resources that would crowd the user's view, or containers whose contents are too broad to sync wholesale — e.g. a holiday or someone-else's shared calendar, a GitHub org that cascades to every repo, a Microsoft Teams team container). The user can still enable it manually.
• undefined — no opinion; the client decides. The client defaults to enabling the channel unless its title looks low-value (holidays, birthdays, spam/sent/draft, …).

The guiding principle is "sync everything the user would reasonably want by default" — for most connectors that's all channels, so only set this where the connector can distinguish the user's own/relevant channels from low-value ones (e.g. Google Calendar via accessRole === "owner").

Optional nested channel resources (e.g., subfolders)

Per-channel link type configs. Overrides twist-level linkTypes when present.
