Per-instance ProcessSupervisor: tokio child spawn with proper arg list
(fixes Go's naive space-splitting), graceful SIGTERM with 30s budget
then force kill, monitor task classifying ordered-stop vs crash (exit
code captured), watch-channel state observable everywhere. Instance cmd
channel live on corrosion.{license}.{instance}.cmd (start/stop/restart/
status) with state events pushed on {instance}.status (keep-latest
semantics, documented). Heartbeats now carry live process state +
uptime per instance. Crate restructured lib+bin for integration tests.
Verified: 5 integration tests with real OS processes (lifecycle, crash
exit-code, restart recovery, unmanaged rejection, clean spawn failure)
+ live-NATS contract test (request-reply roundtrips, double-start
rejection, push events, heartbeat state) — all green.
Known limitation (documented): no PID adoption yet — agent restart
orphans a running game process to 'stopped' until panel restart.

# 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](./PROTOCOL.md) (v2, instance-scoped subjects)
|
|
- **Config**: see [agent.example.toml](./agent.example.toml)
|
|
|
|
## Status — Phase 0
|
|
|
|
- [x] Multi-instance TOML config + env overrides (`CORROSION_LICENSE_ID`, `CORROSION_NATS_URL`, `CORROSION_NATS_TOKEN`)
|
|
- [x] NATS connection (infinite reconnect, capped backoff, 30s ping, offline send-buffering, `tls://` support)
|
|
- [x] Host heartbeat with real telemetry (sysinfo: CPU, memory, disks) — no fabricated values
|
|
- [x] Connectivity prober (outbound TCP, periodic + on-demand)
|
|
- [x] Host command channel (`ping`, `probe`, `sysinfo`)
|
|
- [x] Graceful shutdown (cancellation token, going-offline beacon, NATS flush)
|
|
- [x] Phase 1a: process supervision — per-instance start/stop/restart/status over
|
|
`{instance}.cmd` request-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 3: signed self-update (enforced ed25519 — release gate), service install, supervisor split

## Build
|
|
|

|
cargo build --release # native
|
|
cargo build --release --target x86_64-unknown-linux-gnu # linux deploy target

|
## Run
|
|
|
|
```bash
|
|
corrosion-host-agent --config ./agent.toml # foreground
