Description
Count the inclusive overlap as max(0, min(ends) - max(starts) + 1) across two ordered positive ayah ranges.
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 the inclusive overlap as max(0, min(ends) - max(starts) + 1) across two ordered positive ayah ranges.
When to use this tool
Use Public Ayah Range Overlap when you need a precise source-token or range consistency check.

}Limitations and assumptions
- Shared coordinate meaning must already be established; surah, edition, and actual verse availability are not checked.
- 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.
