# Textunnel physical acceptance summary

Reviewed: 2026-10-18
Maintainer-authored summary of repository acceptance modules 67 and 68.
Canonical explanation: https://textunnel.com/transfer-guide#tested-behavior

These are functional acceptance observations from the October 18, 2026 test record, not speed benchmarks or proof for every browser, VPN or router. Desktop reads were deliberately slowed for interruption tests. In-flight refresh recovery, iOS process eviction and physical Android/Windows coverage remain unverified.

## iPhone Safari ↔ Mac on the same Wi-Fi, at least one VPN enabled

1 MiB and 64 MiB saved and returned over WebRTC; returned SHA-256 matched the source. A 64 MiB rejection also reached the sender correctly.

## iPhone lock screen and background

Uninterrupted transfer did not pass. Returning to Safari reconnected; manual sender Retry resumed verified prefixes, and complete 64 MiB return hashes matched.

## Physical network interruption

After Wi-Fi and cellular were disabled for about 20 seconds and restored, reconnection plus manual Retry resumed a retained prefix; the full 64 MiB return hash matched.

## Offline QR connection

Both real cameras exchanged Offer/Answer QR codes. With desktop WebSocket signaling blocked from context creation, a native host-to-host channel transferred a 1 MiB file with matching return hash. This does not prove an uncached offline first visit.
