Archival digitization & genealogical research background

[TO FILL: author digitization and genealogy experience]

Every guide and interactive calculator on HeirloomMath—including the Photo, Slide & Home Movie Digitization Planner + Local Histogram Workbench and the Tombstone Birth-Date, 1752 Calendar, US Census Window & Cousin DNA Calculator—is checked line by line against primary federal preservation standards (FADGI 3rd Edition May 2023, NARA 36 CFR § 1236.50, Library of Congress Recommended Formats Statements), statutory decennial census enumerator instructions (1790–1950), the British Calendar (New Style) Act 1750, and peer-reviewed population-genetics formulas.

Scanners, film holders, video decks & software used for verification

[TO FILL: author scanners film holders and archive tools]

Empirical scan-time measurements, 256-bin RGB and BT.709 luminance histogram evaluations, and diplomatic AI handwriting transcription benchmarks described across HeirloomMath are designed to be verified on dedicated flatbed and 35mm film scanners, S-Video/TBC video capture chains, and acid-free archival enclosures. Whenever a specific hardware benchmark, scanner timing log, or photographic comparison has not yet been completed on physical test media, the article displays a visible yellow “Field test pending” box describing the exact measurement protocol to be added; see our first-hand testing policy.

Editorial verification standards

  • Optical & storage math: Every pixel matrix, enlargement magnification factor, uncompressed 24-bit/48-bit TIFF byte footprint, and CISA 3-2-1 backup volume is verified with automated unit tests before publication.
  • Calendar, census & genetic math: Every gravestone subtraction example is tested across all four cases of the 8870 borrow constant (K ∈ [0, 70, 8800, 8870]) alongside Backward and Forward Exact calendar subtraction, Julian Day Numbers (JDN), Sewall Wright’s Coefficient of Relationship (r), Donnelly-Coop Poisson segment counts, and NARA American Soundex rules.
