Description
Subtract firstAyah from lastAyah and add one when includeEnd is true.
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.
Subtract firstAyah from lastAyah and add one when includeEnd is true.
When to use this tool

}Limitations and assumptions
- This applies an explicit endpoint convention without validating a surah, edition, or actual verse text.
- 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.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
