Debian-based Docker images install /etc/apt/apt.conf.d/docker-clean which runs 'apt-get clean' after every apt-get install — wipes out /var/cache/apt/archives so there's nothing for actions/cache to save. Fix: remove the docker-clean drop-in and add keep-cache config first thing in each job, before any apt activity. Also bump apt cache key to v2 since the previous v1 was always empty. Wait time on the Wine + Inno Setup step should drop from ~1m20s to ~10s on warm runs (debs already in /var/cache/apt/archives, dpkg just installs them locally).

Drover-Go
Discord proxy / DPI bypass tool. Routes Discord traffic through a SOCKS5 proxy via kernel-level packet capture (WinDivert), bypassing the limitations of in-app proxy settings and surviving Discord auto-updates.
What it solves
Discord doesn't support proxies for voice/video traffic. Existing DLL-injection tools (drover, discord-voice-proxy) modify Discord.exe, which:
- triggers antivirus heuristics (unsigned DLL injecting into a popular app),
- breaks every time Discord auto-updates,
- doesn't proxy
Update.exeitself, so the updater fails when Discord servers are blocked.
Drover-Go uses WinDivert — a Microsoft-signed kernel driver — to capture packets at the network stack level. No modification of Discord, works for any Discord variant (Stable/Canary/PTB/Vesktop), survives auto-updates, minimal AV detection.
Status
Pre-alpha. See implementation plan for details.
How it works
Discord.exe (unmodified)
↓ TCP/UDP
WinDivert.sys (kernel filter)
↓ matched packets
drover.exe (Go)
├── TCP redirect to local SOCKS5 listener → SOCKS5 CONNECT → upstream proxy
└── UDP encapsulation (RFC 1928) → SOCKS5 UDP ASSOCIATE → upstream proxy
For UDP voice that's blocked even via SOCKS5 (DPI on the proxy's TCP control channel), drover-go injects a fake QUIC initial packet (à la zapret-discord-youtube) before forwarding — DPI sees "QUIC to Google" instead of Discord media.
Requirements
- Windows 10 1903+ or Windows 11 (x64). ARM64 not supported by WinDivert.
- Administrator privileges for first run (driver install).
- Upstream SOCKS5 proxy with UDP ASSOCIATE support (e.g.
mihomo,sing-box).
