labkit.app.project.emptySourceRecords

Description

Returns a zero-row struct collection with the same durable field shape as labkit.app.project.sourceRecord. App project factories use this value so the first file selection can assign a portable source without exposing or duplicating its field schema.

Outputs

records

Empty column collection of portable source records.

Failure Behavior

None - The function accepts no inputs and returns the canonical empty collection deterministically.

Example

project.inputs.sources = labkit.app.project.emptySourceRecords();
assert(isempty(project.inputs.sources))
