   Mechanical pass (2026-10-02)

   I scanned all 394 tablets. The checks were: range checks, active area against body size, display aspect ratio, pixel density, included pens against pen-compat, missing core fields, and differences between same-size models in one family. 99 tablets have a notes page.

   Fixed in #58

   • 16 tablets shipped a pen that its pen-compat row didn't list. data-quality now checks for this.
   • Cintiq 24, Cintiq 24 touch and Cintiq 16 (2025 models) had body width and height swapped.
   • Intuos Small Bluetooth had no digitizer type.

   Needs a source check (tablets with a notes page)

   • Intuos 12x12 (GD-1212U, also GD-1212R, XD-1212R, XD-1212U): the active area is recorded as 304.8 x 316.8. A 12x12 tablet should be square.
   • Cintiq 21UX 2010 (DTK-2100) and DTZ-1200W: corner accuracy is 4 mm.
   • Intuos 1 (GD-0405U … GD-1218U), UltraPad (UD-0608A … UD-1825R) and SD-510C: no pressure levels or digitizer type.
   • Intuos Medium CTL-690 vs CTH-690: 2048 vs 1024 pressure levels for the same tablet size.
   • 45 color gamut values over 100%, mostly Huion, XP-Pen and UGEE sRGB, are area figures rather than coverage. These go to Display.ColorGamuts: decide whether values are coverage or relative gamut size #51.

   Needs a source check (no notes page)

   • Huion H610 and Kamvas RDS-160: the body is smaller than the active area.
   • 269 core fields are missing across the remaining tablets, mostly older Wacom models.

   Next: a source pass over the 99 notes-page tablets, comparing each record against its manufacturer spec page or manual (the MANUFACTURERPRODUCTINFO / MANUFACTURERUSERMANUAL links). The same pass can sort each gamut figure into coverage or area (#51) and record coatings (#56).

   Conventions decided by Seven (2026-10-02)

   1. Color depth: Display.ColorBitDepth keeps the panel's native depth (6, 8 or 10). A new Display.ColorBitDepthFRC holds the depth the manufacturer claims with FRC, and is set only when they say FRC ("8-bit + FRC", "1.07B colors" on an 8-bit panel). The Specs row reads "8-bit (10-bit with FRC)" when both are set, and "10-bit" for a true 10-bit panel. Recheck the 20 tablets recorded as 10-bit today, since some are likely 8-bit + FRC.
   2. Buttons means programmable buttons only. Count multimedia keys in their own field, and scrollers in their own field.
   3. Depth ranges ("19~26.7 mm"): store a distinct min and max. If only one value is given, it is the max.
   4. Hover ranges: undecided. Count how many sources give a range first.
   5. A single accuracy figure with no center/corner split: store it as center accuracy.
   6. A built-in fold-out stand counts as Legs only, not IncludedStand.
   7. Report rate: store both wired and Bluetooth. If only one value is given, it is the wired one.

   Seven's answers (2026-10-02 21:27 UTC)

   These map to the numbered questions Seven was asked:

   1. HS610: merge. Merge the "H610" record (huion.tablet.h610) into the existing huion.tablet.hs610, keeping its 12 buttons and 1 touch ring, delete the H610 record, and point the pen-compat entry for "H610" at HS610. Seven: the HS610 is discontinued.
   2. Intuos 1 ADB (GD-…-A): yes. Copy the digitizer specs from the -R/-U versions: 1024 levels, EMR, ±0.25 mm center accuracy, hover, report rate.
   3. UltraPad: yes. Use Wacom's 1997 figures:
      • 6×8 weight 862 g
      • 12×12 size 406 × 419 × 51 mm
      • 12×18 weight 3402 g
      • 18×25 active area 635 × 457.2 mm at 100 lines/mm
   4. Hover ranges: yes. On the two Magic Drawing Pads, store a min and a max like depth: 10 and 20 mm.
   5. Inspiroy 2 L group keys: yes, their own field. Seven: they are "switcher" keys, not assignable in the normal sense for shortcuts.
   6. Go live: yes. Merge the spec-audit-2 batch (audit fixes, conventions, and the answers above) into DrawTabData master and DrawingTabletDocs syncbranch.
