Default UI Behavior

When ui is not specified, the system uses these defaults:

Property Type	Default UI Component	Description
string	input	Single-line text box
number / integer	number-input	Number input box
boolean	switch	Toggle switch
object	(no container)	Child fields laid out flat
array	array-section	Array panel, auto mode detection
credential_id	credential-select	Credential selector
encrypted_string	encrypted-input	Password input box
file_ref	input	Expression-only input, AI override always disabled
discriminated_union	select (discriminator)	Selector + variant panel
resource_locator	Mode selector + input	List mode: searchable dropdown; url/id modes: text input
resource_mapper	Manual field rows	One typed input per field; auto mode: JSON editor

Array Section Auto Mode Selection

When array type has no UI specified or uses array-section:

• Simple mode: items is basic type (string / number / boolean)

  • One input per row + delete button
  • "Add" button at bottom

• Compound mode: items is object

  • Each item renders as collapsible panel
  • Panel title shows sequence number
  • Each item has independent delete button
