The 'Sign artifacts' step failed on alpha.7 with 'Error while loading the secret key file' (exit 2): minisign downloaded and ran, but the reconstructed key file was unparseable. A minisign secret key is two lines (comment + base64 blob); Gitea/act_runner secret storage mangles the embedded newline, collapsing it to one line. Decode the secret as base64 (single-line, mangling-proof) with auto-detect fallback to a raw two-line key. Fails loudly with the fix command if the secret is neither form. Requires re-storing MINISIGN_SECRET_KEY as: base64 < secret.key | tr -d '\n' Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Corrosion Host Agent
Rust rewrite of the Go companion agent (companion-agent/, retained as the
behavior reference until parity). One agent per machine supervises every game
instance on that host — Rust, Conan Exiles, Soulmask, Dune: Awakening.
- Wire protocol: see PROTOCOL.md (v2, instance-scoped subjects)
- Config: see agent.example.toml
Status — Phase 0
- Multi-instance TOML config + env overrides (
CORROSION_LICENSE_ID,CORROSION_NATS_URL,CORROSION_NATS_TOKEN) - NATS connection (infinite reconnect, capped backoff, 30s ping, offline send-buffering,
tls://support) - Host heartbeat with real telemetry (sysinfo: CPU, memory, disks) — no fabricated values
- Connectivity prober (outbound TCP, periodic + on-demand)
- Host command channel (
ping,probe,sysinfo) - Graceful shutdown (cancellation token, going-offline beacon, NATS flush)
- Phase 1a: process supervision — per-instance start/stop/restart/status over
{instance}.cmdrequest-reply, push state events on{instance}.status, crash detection with exit codes, live state in heartbeats (integration-tested with real processes + live-NATS contract test) - Phase 1b: RCON trait (WebRCON rust / TCP conan+soulmask), SteamCMD, jailed file manager
- Phase 2: Dune Docker adapter (compose lifecycle, RabbitMQ bus, Postgres admin)
- Phase 3a: SIGNED self-update — minisign-verified download+swap+relaunch (NATS
updatefunc); embedded public key; CI signs releases - Phase 3b: service install (systemd/SCM), PID adoption
