Lands the protocol layer end-to-end: an agent can be enrolled through the operator UI, store credentials, dial back to the server over WS, complete the protocol_version handshake, and stay connected with periodic heartbeats. Server side: - P1-09 ws.Hub: one Conn per host_id, last-write-wins eviction, json envelope writer with a write mutex, reader, error envelopes. - P1-09 ws.AgentHandler: bearer-auth, accept upgrade, hello-stage (10s deadline, protocol_version checked against api.MinAgentProtocolVersion → ErrProtocolTooOld with help URL on reject), main read loop, defer hub register/unregister. - P1-10 POST /api/agents/enroll consumes a one-time token, mints a persistent agent bearer (sha-256 stored), creates a host row. - P1-10 POST /api/enrollment-tokens (operator, session-auth) issues a 1h one-time token. - P1-11 hello upserts agent_version + restic_version + protocol_version on the host row, flips status to online. - P1-12 heartbeat touches last_seen_at; background sweeper marks hosts offline after 90s without one. - store: hosts table accessors, host_schedule_version, enrollment_tokens FK on consumed_host dropped (audit-only field; the token gets burned before the host row exists). Agent side: - P1-13 internal/agent/config: yaml at /etc/restic-manager/agent.yaml, atomic Save (tmp+fsync+rename), Enrolled() helper. - P1-15 internal/agent/wsclient: dial with bearer + optional TLS cert pinning (sha-256 of leaf), exponential backoff with jitter (1s → 60s cap), heartbeat goroutine, fatal handling for ErrProtocolTooOld. - P1-15 wsclient.Enroll: HTTP POST /api/agents/enroll with sysinfo. - P1-17 internal/agent/sysinfo: hostname/OS/arch/restic-version collection. restic detected by `restic version` parse; absent restic doesn't block startup. - cmd/agent: -enroll-server / -enroll-token flags drive first-run enrollment then exit (so the install script can hand off to systemd to run the persistent service). End-to-end smoke verified: bootstrap → login → issue token → enroll → run agent → server logs `ws agent connected` with the right host_id and protocol_version 1. All tests still pass.

restic-manager
Self-hosted, browser-based, single-pane-of-glass for managing restic backups across a fleet of Linux and Windows endpoints.
Status: pre-alpha. Phase 0 (project bootstrap) complete; Phase 1 (MVP) in progress. See
spec.mdfor the design andtasks.mdfor the roadmap.
What it does (target)
- Central visibility into backup state for every endpoint
- Trigger any restic operation remotely (
backup,forget,prune,check,unlock,snapshots,stats,diff,restore) - Manage per-host backup schedules from the UI
- Live job progress streamed back to the UI
- Restore wizard (browse snapshots, pick paths, restore to original or alternate host)
- Repo health surfacing (size, dedup ratio, last check, lock state)
- Alerting on failure or staleness
- Cross-platform agent (Linux + Windows)
- Ransomware-resistant repo access via append-only credentials
Architecture (one-line summary)
A small Go control-plane on the Proxmox host, lightweight Go agents on each
endpoint that hold an outbound WebSocket to the control-plane, and a
restic/rest-server on Unraid that holds the actual backup data. The
control-plane never touches backup bytes.
Full architecture diagram and component breakdown:

Local development
Requires Go 1.25+ (built and tested on 1.26). The floor is set by
modernc.org/sqlite v1.50.
make build # builds cmd/server and cmd/agent into ./bin
make test # runs go test ./...
make lint # runs golangci-lint
make run-server # runs the server (dev defaults)
