// Records omitted because the table declares a contradiction.
//
// - `coedge` (size_mismatch): The stated offsets end `chunk[10]` at +99 but the heading declares 100 B. Shifting every stated offset by +1 (head 9 bytes rather than 8, matching the `coedge` name-token length) closes the record at 100; so does leaving the offsets alone and declaring 99 B. The spec does not say which side is wrong.
// - `edge` (size_mismatch): The stated offsets end the continuity text at +99 but the heading declares 98 B. Removing the one-byte gap at +88 (placing the sense byte at +88 and the text at +89) closes the record at 98 exactly, which suggests both trailing offsets are one too high. The spec does not state which.
