Documents how each backup path has actually been exercised — Google
Auto Backup verified on emulator (status card, blob round-trip via local
transport, restore card by screenshot; decrypt+import by instrumented
test since ADB can't tap the Compose dialog reliably), file import/
export verified earlier, S3 still pending a live bucket. Captures the
scrypt wf=15 rationale and the safe real-hardware test protocol.
