The temperature collection in pulse-host-agent was broken on all Linux
distributions due to an incorrect platform check.
Root cause:
- collectTemperatures() checked `if a.platform != "linux"` at agent.go:316
- normalisePlatform() returns the raw distro name from gopsutil (debian, ubuntu, pve)
- This caused temperature collection to be skipped on ALL Linux hosts
Fix:
- Changed check to `if runtime.GOOS != "linux"` which correctly identifies Linux
- runtime.GOOS returns "linux" regardless of distribution
Also fixed documentation typo:
- Changed "Servers tab" to "Hosts tab" in HOST_AGENT.md and TEMPERATURE_MONITORING.md
- Reported by user in issue #661 comments
Testing:
- Verified build succeeds
- Confirmed runtime.GOOS returns "linux" on Linux systems

Implements temperature monitoring in pulse-host-agent to support Docker-in-VM
deployments where the sensor proxy socket cannot cross VM boundaries.
Changes:
- Create internal/sensors package with local collection and parsing
- Add temperature collection to host agent (Linux only, best-effort)
- Support CPU package/core, NVMe, and GPU temperature sensors
- Update TEMPERATURE_MONITORING.md with Docker-in-VM setup instructions
- Update HOST_AGENT.md to document temperature feature
The host agent now automatically collects temperature data on Linux systems
with lm-sensors installed. This provides an alternative path for temperature
monitoring when running Pulse in a VM, avoiding the unix socket limitation.
Temperature collection is best-effort and fails gracefully if lm-sensors is
not available, ensuring other metrics continue to be reported.

Windows Host Agent Enhancements:
- Implement native Windows service support using golang.org/x/sys/windows/svc
- Add Windows Event Log integration for troubleshooting
- Create professional PowerShell installation/uninstallation scripts
- Add process termination and retry logic to handle Windows file locking
- Register uninstall endpoint at /uninstall-host-agent.ps1
Host Agent UI Improvements:
- Add expandable drawer to Hosts page (click row to view details)
- Display system info, network interfaces, disks, and temperatures in cards
- Replace status badges with subtle colored indicators
- Remove redundant master-detail sidebar layout
- Add search filtering for hosts
Technical Details:
- service_windows.go: Windows service lifecycle management with graceful shutdown
- service_stub.go: Cross-platform compatibility for non-Windows builds
- install-host-agent.ps1: Full Windows installation with validation
- uninstall-host-agent.ps1: Clean removal with process termination and retries
- HostsOverview.tsx: Expandable row pattern matching Docker/Proxmox pages
Files Added:
- cmd/pulse-host-agent/service_windows.go
- cmd/pulse-host-agent/service_stub.go
- scripts/install-host-agent.ps1
- scripts/uninstall-host-agent.ps1
- frontend-modern/src/components/Hosts/HostsOverview.tsx
- frontend-modern/src/components/Hosts/HostsFilter.tsx
The Windows service now starts reliably with automatic restart on failure,
and the uninstall script handles file locking gracefully without requiring reboots.
Introduces granular permission scopes for API tokens (docker:report, docker:manage, host-agent:report, monitoring:read/write, settings:read/write) allowing tokens to be restricted to minimum required access. Legacy tokens default to full access until scopes are explicitly configured.
Adds standalone host agent for monitoring Linux, macOS, and Windows servers outside Proxmox/Docker estates. New Servers workspace in UI displays uptime, OS metadata, and capacity metrics from enrolled agents.
Includes comprehensive token management UI overhaul with scope presets, inline editing, and visual scope indicators.
