Record format: question; proposed response; source or method; limitation. Use a dated correction only if the underlying wording or evidence changes. Record RWF-28132.
Use the same numeral, camera axis and approximate image scale. Keep the uncropped originals alongside the detail crops and distinguish optical balance from physical window alignment.
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Use the same numeral, camera axis…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.
Method note for “Date window centring: compare the same date at the same angle”: use “Use the same numeral, camera axis…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.
