- Preserve raw Cloudflare subnets in community-subnets-discord.lst in updates.uc instead of destructive deletion.
- In singbox/generator_routes.uc:
* Exclude Cloudflare Anycast CIDRs from general IP route rules (preventing web hijacking).
* Generate a dedicated Discord Voice route rule for Cloudflare subnets scoped to network: 'udp' and voice port ranges (50000-65535, 3478, 19302, 5000-5020).
* Provide DEFAULT_DISCORD_VOICE_SUBNETS fallback in core/ip.uc.
- In nft/apply.uc:
* Route Cloudflare subnets to ip_ports set with Discord voice ports (5000-5020, 3478, 19302, 50000-65535).
* Automatically enable ip_port rules when section has community_subnets for Discord.
- In section.js (Routing Rule Tracer):
* Filter out Cloudflare subnets when resolving domain web traffic to Discord community subnets.
* Accurately display voice UDP routing notice for Anycast ranges.
- Update tests/community_subnets_sanitization.sh with voice UDP and sing-box validation.
- Replace invalid POSIX non-capturing group in diagnostics/runtime.uc with standard POSIX ERE pattern.
- Harden 99-tachyon-wan-monitor with stale PID directory lock cleanup and dynamic badwan_reload_delay support.
- Make is_cloudflare_shared_cidr in core/ip.uc case-insensitive.
- Add default wan to badwan_monitored_interfaces in settings.js.
- Fix#50: Discord community subnets hijacking Cloudflare Anycast traffic:
* Filter broad Cloudflare shared subnets (104.16.0.0/12, 172.64.0.0/13, etc.) for Discord preset in generator_routes.uc, nft/apply.uc, and updates.uc.
* Add tachyon resolve_domain CLI and runtime.uc helper for DNS queries with rpcd ACL support.
* Update LuCI Routing Rule Tracer to resolve queried domains against section subnets/CIDRs (including community subnets) and show shared CDN/Anycast warnings.
* Add unit tests in tests/community_subnets_sanitization.sh.
- Fix#51: Telegram bot spamming WAN up/down notifications on hotplug:
* Check enable_badwan_interface_monitoring, telegram.enabled, and badwan_monitored_interfaces list in 99-tachyon-wan-monitor.
* Add background debounce with atomic directory locking and ubus interface status verification.
* Implement state transition tracking to only notify on actual UP->DOWN and DOWN->UP changes without duplicates.
* Preserve retry_start_on_wan_up behavior on ifup.
* Add comprehensive integration test suite in tests/wan_monitor_hotplug.sh.
