| 1 | # CKey Format v0.22.0 — Profile 2 Corrected Finder Clearance |
| 2 | |
| 3 | Profile 2 retains its 29-unit field, 58×58 Cartesian pitch, eight ring rows, |
| 4 | 144 radial slots, full RS(255,210) protection, and deterministic visual fill. |
| 5 | |
| 6 | Cartesian payload clearance at each corner is limited to the actual outside |
| 7 | quadrant of the curved finder and its measured stroke guard. It is not a |
| 8 | square corner reservation. This removes the four dead corner squares while |
| 9 | keeping data separated from both the rounded frame and finder ink. |
| 10 | |
| 11 | Encoders emit frame format byte `0x16` (decimal 22), profile byte `0x02`. |
| 12 | This changes the Profile 2 codeword-to-site mapping and requires the v0.22 |
| 13 | sampling map. |
