Opt-in WiFi speed sampling for venue accountability

[JacobCoffee]

Crowdsource WiFi download speed samples from attendees to build evidence for venue negotiations when advertised speeds aren't delivered.

Flow:

• On first app open, show opt-in popup explaining purpose ("Help us improve PyCon WiFi — anonymously sample your connection speed periodically")
• If opted in, periodically (every ~5 min while app is in foreground) download a small fixed-size asset and measure throughput
• POST anonymized result to a simple endpoint: {timestamp, speed_mbps, ssid}
• No location, no user ID, no PII

Staff side:

• Simple dashboard or export showing speed distribution over time
• Usable as evidence in venue contract negotiations

Implementation notes:

• Opt-in preference stored in Ionic Storage
• Speed test: fetch a ~100KB asset from S3/CDN, measure elapsed time
• iOS restricts background execution, so foreground-only is fine
• SSID available on Android easily; iOS needs location permission + entitlement (could skip SSID on iOS and just record speed)
• Needs a new endpoint on pycon-site to receive samples
