- Bump version/FileVersion to 1.1.1 - Verify in-app update checker points to XboxFastZ releases - Preserve v1.1.0 Network Diagnostics, branding, and attribution
The updater downloaded XboxDownload-{os}-{arch}.zip but the publish
script produces XboxFastz-{os}-{arch}.zip, so in-app updates would 404.
Use the branded asset name so releases download correctly.
Add EndpointSelectorService for automatic, low-bandwidth endpoint/IP selection using a cheap-to-expensive funnel: ICMP reachability/latency -> small HTTP latency probes (packet-loss estimation) -> small 4MB ranged speed test on the most promising candidates -> rank by speed -> automatic selection. Wire it into the Fastest Akamai IP auto-feature with the legacy race-based selector retained as fallback. The Speed Test tab workflow and per-IP full speed test remain unchanged. Bump version/FileVersion to 1.2.0.
Corrective commit on top of fb62c15. The previous v1.2.0 implementation fed IP.*.txt candidates into EndpointSelectorService, which violated the independence requirement. EndpointSelectorService now discovers candidates by DNS-resolving the bounded, hardcoded download-domain catalog in DnsMappingGenerator.HostRules (capped at 60 IPs) instead of reading IP.*.txt. The cheap-to-expensive funnel is preserved: ICMP reachability -> tiny HTTP latency probes -> 4MB ranged speed test on the top 5 finalists -> rank by measured throughput (latency tie-break) -> automatic selection. ServiceViewModel.FastestAkamaiIpAsync no longer loads/parses IP.AkamaiV2.txt and no longer falls back to the legacy IP-file race selector. On discovery failure the currently working endpoint is preserved via a clear EndpointDiscoveryResult; no silent IP-file fallback. The legacy IP-file infrastructure is retained for the Speed Test tab and backward compatibility; it is not deleted. SpeedTestService is not rewritten.
