no packages provided to collate

Error message

no packages provided to collate

What it means

Returned by CreateSignedCCDepSpecForInstall's collation path when the owners slice is empty — no owner-signed packages were supplied to merge. Collating zero packages would produce an unendorsed install package, which the function's contract forbids.

Solutions

1. Pass at least one package produced by OwnerCreateSignedCCDepSpec
2. Check upstream slicing/filtering logic that may have emptied the package list
