agent-orchestrator

Rewrite of the agent-orchestrator: a long-running Go backend daemon (backend/)
paired with an Electron + TypeScript frontend (frontend/).

See docs/ for architecture and status — start with the
Lifecycle Manager + Session Manager lane in docs/architecture.md.

Backend daemon

The Go backend now has a Cobra-based ao CLI in backend/cmd/ao.
The CLI controls the HTTP daemon — a loopback-only sidecar the Electron
supervisor will also use. The daemon skeleton includes the chi router,
middleware stack (recoverer → request-id → logger → real-ip), /healthz +
/readyz, atomic running.json PID/port handshake, graceful shutdown on
SIGINT/SIGTERM, SQLite storage, CDC polling, and lifecycle/reaper wiring.

Run

cd backend
go run ./cmd/ao start             # start the daemon and wait for readiness
go run ./cmd/ao status            # inspect PID/port/health/readiness
go run ./cmd/ao stop              # gracefully stop the daemon
go run ./cmd/ao daemon            # internal daemon entrypoint

go run .                          # compatibility wrapper; starts the daemon
AO_PORT=3019 go run ./cmd/ao start # override per invocation

Health check:

curl localhost:3001/healthz       # {"status":"ok"}
curl localhost:3001/readyz        # {"status":"ready"}

Configuration (env only)

The bind host is always 127.0.0.1: the daemon is a loopback-only sidecar
and binding any other interface would be a security regression, so the host
is intentionally not env-configurable.

Var	Default	Purpose
AO_PORT	3001	bind port; fails fast if taken
AO_REQUEST_TIMEOUT	60s	per-request timeout (Go duration)
AO_SHUTDOWN_TIMEOUT	10s	graceful-shutdown hard cap
AO_RUN_FILE	<UserConfigDir>/agent-orchestrator/running.json	PID + port handshake path

Test

cd backend
gofmt -l . && go build ./... && go vet ./... && go test -race ./...
