XQD and CFexpress: check the reader, not just the outline
An explicit support statement is more useful than a successful-looking fit.
The useful distinction
The Sony statement covers specified XQD series, not every card carrying an XQD label. The worksheet repeats this limitation rather than displaying a universal green compatibility result.
Existing evidence:C134A · C134B · C138A · C138B/ source records S096 · S437 · S106 · S107. See each source record for its inspection date and scope; graphic interpretation remains pending independent technical and publication review.
The useful distinction
Understand the requirement.
Similar physical forms do not establish shared reader support. [C138A]
ProGrade PG05.5 and PG05.7 explicitly exclude XQD. [C138B]

Scoped documentation

Scoped documentation
ProGrade PG05.5 and PG05.7 explicitly exclude XQD. [C138B]
Verified device list
Not included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.
For the listed ProGrade models, the exclusion is a publisher statement. For other models, an absent XQD statement remains not documented, rather than automatically becoming an exclusion.

What to check
Keep CFexpress Type B and XQD as separate selections.
Read the exact reader model and any supported-card series.
Treat missing support as unknown; use exclusions only when documented.
AI-assisted inspection is not independent engineering review. Source scope and access limitations are disclosed below. Procedural checklists are editorial requirements, not hardware measurements.
