Description

Compare supplied premise arity under an explicit duplicate policy; no inference validity judgment.

A logical calculation operates on a stated representation: truth values, token lists, counts, or an explicitly supplied relation. Checking one assignment, pair, trace, or witness is different from proving a formula or validating an entire argument. Empty domains, duplicate tokens, and scope conventions can change the result.

Compare supplied premise arity under an explicit duplicate policy; no inference validity judgment.

When to use this tool

Use Inference Premise Arity Gap when you need this exact local truth, count, token, relation, or witness check within a larger logic workflow.

How to use the tool and how it works

  1. Enter premiseIds, requiredArity, duplicatesCountSeparately. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read effectiveArity, gap, matches. Inspect matches before interpreting the associated values.

For nonnegative integer requiredArity count premiseIds separately if duplicatesCountSeparately, otherwise count distinct IDs. Return effectiveArity, gap=effectiveArity-requiredArity, and matches on equality.1

Limitations and assumptions

  • This compares premise counts under the supplied duplicate policy. It does not check premise truth, rule applicability, types, or inference validity.
  • 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. Signed zero is exported as zero.

Alternative or Complementary methods

Use a parser, scope-aware representation, model checker, or proof procedure when the supplied token or witness representation is insufficient. A local passing check should not be promoted to global validity.
