- Add /healthz (liveness) and /readyz (readiness) endpoints
- Add /metrics endpoint with Prometheus metrics (pulse_agent_info, pulse_agent_up)
- Properly call dockerAgent.Close() on shutdown
- New config: -health-addr flag and PULSE_HEALTH_ADDR env (default :9191)
- Set to empty string to disable health server
53 test cases covering 4 functions:
- gatherTags: environment/flag tag merging (18 cases)
- parseLogLevel: log level parsing (30 cases)
- defaultLogLevel: default value resolution (10 cases)
- multiValue: flag.Value interface for repeatable flags (6 cases)
Key difference from pulse-host-agent: parseLogLevel in unified agent delegates
directly to zerolog.ParseLevel without range validation, so trace/fatal/panic
levels are accepted (unlike pulse-host-agent which restricts to debug-error).
First test file for cmd/pulse-agent package.
Port Windows SCM integration from pulse-host-agent to pulse-agent,
enabling the unified agent to run as a Windows service with proper
start/stop handling and event logging.

Issues found during scenario testing:
1. Version propagation: The hostagent and dockeragent packages were
reporting their own Version (0.1.0-dev) instead of the unified
agent's version. Added AgentVersion config field to pass the
parent's version down.
2. macOS legacy cleanup: The install.sh script was missing cleanup
for pulse-docker-agent on macOS.
3. Windows legacy cleanup: The install.ps1 script was missing cleanup
for legacy PulseHostAgent and PulseDockerAgent services.
These fixes ensure:
- Unified agent reports consistent version across host/docker metrics
- Legacy agents are properly removed on all platforms during upgrade
- Users migrating from legacy agents get a clean transition
Add seamless migration path from legacy agents to unified agent:
- Add AgentType field to report payloads (unified vs legacy detection)
- Update server to detect legacy agents by type instead of version
- Add UI banner showing upgrade command when legacy agents are detected
- Add deprecation notice to install-host-agent.ps1
- Create install-docker-agent.sh stub that redirects to unified installer
Legacy agents (pulse-host-agent, pulse-docker-agent) now show a "Legacy"
badge in the UI with a one-click copy command to upgrade to the unified
agent.
Implement self-update capability for the unified pulse-agent binary:
- Add internal/agentupdate package with cross-platform update logic
- Hourly version checks against /api/agent/version endpoint
- SHA256 checksum verification for downloaded binaries
- Atomic binary replacement with backup/rollback on failure
- Support for Linux, macOS, and Windows (10 platform/arch combinations)
Build and release changes:
- Dockerfile builds unified agent for all platforms
- build-release.sh includes unified agent in release artifacts
- validate-release.sh validates unified agent binaries
- Install scripts (install.sh, install.ps1) use correct URL format
