Description
Require positive page and column and a listed direction, then format all three in a label.
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.

|---|---|---|
| page | Page | Required. Safe integer; minimum 1. |

{
"input": {
"page": 12,
"column": 3,
"direction": "right-to-left"
},
"output": {
"label": "page 12, column 3 (right-to-left)"
}
}Limitations and assumptions
- The direction is supplied rather than inferred; layout, source numbering, reading order, and actual column content 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.
