It does not fetch the cited books, search a corpus or inspect current policy. Unsupported tokens and added whitespace are input errors. Reference entries are bibliographic pointers rather than retrieved source passages; read the limitations alongside the summary. This bounded card is not a complete reference database.

}Limitations and assumptions
The conventional emperor sequence is therefore different from a set of exclusive reign intervals. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
