Campaign Reason: Historical record from campaign 009-complete-clean-contract-bound-a-b-qualification; retained independently after campaign closure and requires no separate owner-queue execution.

## Result

Controller A, physical asset `1751219`, was cold-started without an SD card.
The owner observed the expected no-SD warning during startup. A live J-Link
sample then confirmed:

- startup complete: `0xC00000FF`;
- configuration operational with no findings/events, generation 6;
- SD service unavailable/no-media diagnostics present (`0x90` status values);
- controller remained attached and readable through J-Link.

The warning-display acceptance gate passes. Dismissal behavior, no-repeat latch,
visible control/UI operation, About-screen text, and bounded no-card shutdown
remain in the grouped operator worksheet.
