node v0.3.1 — roam byte-accounting fix

The observer no longer resets the per-session byte baseline on an endpoint roam, so bytes transferred before a mid-session source-IP change are no longer lost — the full session delta is reported at disconnect. Pairs with coxswain v0.4.1.

node v0.3.0 — per-session byte accounting

Observer now tracks per-session rx/tx deltas (baseline at connect, delta at disconnect; counter-reset + endpoint-roam guards) and reports them in PEER_DISCONNECTED events. Pairs with coxswain v0.4.0.

node v0.2.0 — Live monitoring + hardening

node v0.2.0 — Live monitoring + control-plane hardening

• Observer emits session connect/disconnect events carrying the client source endpoint (powers the controller's monitoring + analytics).
• Drop-counter visibility + graceful-shutdown disconnects (no dangling sessions).
• applied_revision + handshake-liveness in GetStatus (enables controller drift/stale detection).
• Atomic-rename binary install (fixes cox nodes update on a running agent).

Single static binary.
