Breach transfer comparison

Same recovered Breach app, two SDK revisions. Use the same choice on both devices and transfer the same file in the same direction.

Reference SDK 00dfcb1

Current SDK 7ad431c

Both use the existing peer channel, 64 KiB chunks and eight requests. Neither uses Share's live membership or distribution scheduler. The reference is preserved source, not a verified copy of the previously fast deployment.

Keep both pages visible. Each demo exports diagnostics. Compare actual file completion and verification; this is not the raw ramp test.
