Description
Return observation-issued age, a nonfuture age<=maximum flag and a JSON key [source,edition,issuedYear].
Extension-service records track resources, attendance, feedback and permission assertions. Distinct people and repeated records have different denominators, and a complete record does not prove valid consent or a high-quality service. Names such as verified describe caller-supplied evidence flags.
Return observation-issued age, a nonfuture age<=maximum flag and a JSON key [source,edition,issuedYear].
When to use this tool
Use Agricultural Advice Source Vintage Tag when checking the stated extension-service record, participation or permission convention.
How to use the tool and how it works
- Enter source, edition, issuedYear, observationYear, suppliedMaxAge. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read ageYears, withinVintage, key. Inspect withinVintage before interpreting the associated values.
Require whole issued/observation years and nonnegative whole maximum age. Return observation-issued age, a nonfuture age<=maximum flag and a JSON key [source,edition,issuedYear].1

}Limitations and assumptions
- A negative age is retained for future sources; the supplied vintage limit does not establish current or accurate advice.
- 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.
Alternative or Complementary methods
Review original service and participant records and the applicable permission/organizational rules for actual use or reporting decisions.
