Description
Inspect explicitly listed directed accessibility edges without assuming modal frame axioms.
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.
Inspect explicitly listed directed accessibility edges without assuming modal frame axioms.
When to use this tool
Use Modal Accessibility Edge Flag 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
- Enter source, target, sources, targets. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read accessible, edgeCount. Inspect accessible before interpreting the associated values.
Require equally sized sources and targets; return accessible when any pair equals the queried source and target, plus edgeCount counting every matching pair.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| source | Source | Required. Text; maximum UTF-16 length 8192. |
| target | Target | Required. Text; maximum UTF-16 length 8192. |
| sources | Sources | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| targets | Targets | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| accessible | Accessible | Required. Boolean. |
| edgeCount | Edge Count | Required. Safe integer. |

}Limitations and assumptions
- Duplicate edges increase edgeCount but do not change accessibility. No transitive closure, domain validation, modal reasoning, or inferred path reachability is performed.
- 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.
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.
