OpenHardwareOS v0.1.6 — 后台规则服务

OpenHardwareOS v0.1.6 adds a background rules service: closing the desktop window no longer stops the rules. It exists because of the problem underneath it — two processes driving one fan. Existing v0.1.0 – v0.1.5 tags and downloads remain available.

Changes

The rules keep running with no window open

• ohm-cli service run starts the runtime and the rule loop in a process that never opens a window. It runs until Ctrl-C or SIGTERM.
• ohm-cli service status reports from the state file: pid, start time, heartbeat age, cycles, rules, whether the sources are simulated, whether writes are dry-run. It exits 1 when nothing is running and 0 when something is, so a script can ask.
• docs/background-service.md documents the semantics, a systemd user unit template, the permission reality (reading needs no privileges; writing pwm<N> is not implemented in this build at all), and what is not verified.

One writer per channel

• The service claims the hardware channels before touching them, by creating a state file atomically: two processes starting together — or two that both decide an abandoned file is reclaimable — cannot both win.
• Liveness is a heartbeat, not a guess: the owner rewrites the file every second, so a file whose heartbeat stopped belongs to a process that died, including one killed with SIGKILL. A file that cannot be parsed counts as unowned, because refusing to start over a hand-broken file would leave a machine unable to run its rules until somebody deleted it by hand.
• The desktop stands down. When another process owns the channels, the desktop does not start its own rule loop; it keeps reading and drawing, and records why in the log and the event feed instead of silently doing nothing.

Stopping hands control back

• SIGTERM (what a service manager sends) and Ctrl-C stop the rule loop, shut the runtime down — which releases control and reports what that achieved, confirmed and unconfirmed and refused and failed separately — and remove the state file.
• The signal handler is installed before the state file is claimed, so a service that looks alive can always be stopped cleanly.
• The page says plainly why kill -9 is the wrong way to stop it: nothing hands control back, so the fans stay at the last value written.

Install

• Windows: PowerShell instructions for this version
• Linux: CLI, Debian package and AppImage instructions
• Running the rules in the background — new in this version

The Windows desktop installer and the optional PowerShell script are unsigned, and so are the Linux packages. LibreHardwareMonitor is a separate prerequisite for supported motherboard channels on Windows and is not bundled.
