From 7a9dbadb5725f9b0e190ecf28527ee8b72276942 Mon Sep 17 00:00:00 2001 From: Snider Date: Sun, 26 Apr 2026 00:13:18 +0100 Subject: [PATCH] feat(agent/fleet): core login CODE + fleet connect/poll/heartbeat (#539) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per RFC §9 Fleet Mode: device pairing + SSE-with-poll-fallback + heartbeat + status reporting now wired. Lands: * pkg/agentic/fleet_login.go — `core login CODE` POSTs /v1/device/pair with the 6-digit code; writes {agent_api_key, agent_id, expires_at} to ~/.core/agent.key (mode 0600). Errors clean (no panic) on invalid code / network fail. * pkg/agentic/fleet_connect.go — Connect(ctx) opens SSE to /v1/fleet/events with Bearer auth; reconnect backoff 1s→2s→4s→8s→ 16s→30s. PollFallback via /v1/fleet/task/next every 30s when SSE keeps failing. Heartbeat goroutine POSTs /v1/fleet/heartbeat every 60s with {agent_id, status}. Persists last-known fleet snapshot to ~/.core/fleet.status.json so fleet/status survives restart. * pkg/agentic/fleet_mode.go — `core fleet` top-level + `fleet/nodes` (lists registered nodes) + `fleet/status` (connection state, last heartbeat, last task). All exit cleanly on API-unreachable. * commands.go — registerFleetCommands wired into registerCommands. * AX-10 tests + CLI Taskfiles for login + nodes (unreachable-API asserted clean-exit, no panic). Sandbox blocked from go test by go.work + private-module-graph (pre-existing); gofmt clean.
