}Limitations and assumptions
The supplied registry, source, context, and date are records, not independently authenticated evidence. There is no built-in complete or current tax database. Rates, deadlines, exemptions, qualifications, and exceptions must be verified for the actual case before supplying a record.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Evidence arrays must be dense, with no missing cells. String lists allow at most 128 strings of at most 128 characters. Extremely large text is rejected. Extremely large composite outputs are rejected.
Alternative or Complementary methods

This checker applies separately supplied class requirements and retains incomplete or overlapping possibilities. For a complementary step, use Permanent Establishment Days Nexus Checker: Overlapping presence intervals should not count the same day twice. Their union can be compared with a supplied treaty nexus threshold while leaving other permanent-establishment facts separate.
