Description
Count distinct exact sourceIds with a set and return distinctSources.
Source-scoped cultural and historical records preserve an edition, naming convention, or local identifier. Literal agreement is useful bookkeeping but does not establish interpretation, authenticity, or authority.
Count distinct exact sourceIds with a set and return distinctSources.
When to use this tool

}Limitations and assumptions
- Source labels are not resolved to authoritative identities; a larger count does not establish independent corroboration or community authorization.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Consult the source edition and relevant community or scholarly guidance before interpreting or reusing the material.
