v1.1.2 — code-audit fixes

Bug fixes from a full code audit (all backward-compatible):

• --once no longer hangs when the cooler isn't found — it makes one attempt and exits.
• A transient sensor read error no longer crashes the daemon (e.g. hwmon renumbering on suspend/resume) — the frame is skipped and it continues.
• self-update reports failure instead of falsely claiming success if the service restart fails.
• install.sh: AW5D_BIN_DIR to a system dir now sudo-writes the launcher; a missing systemd --user session fails early with a clear message; --uninstall cleans up config + the bootstrap checkout; sed metachars in the Python path are escaped.
• just set-interval edits only the interval line instead of overwriting the whole config file.
• Clean shutdown (no traceback on an ill-timed SIGTERM), plus regression tests for --once.

v1.1.1 — installer fix

Patch: the installer now actually works.

install.sh's shell function was named install, which shadowed the coreutils install command it uses to copy files — so it recursed into itself instead of installing (a latent bug in v1.0.0 and v1.1.0). Renamed to do_install.

If you tried the one-liner before and it spun forever printing installing driver…, that's this — please update and retry:

curl -fsSL https://raw.githubusercontent.com/claygorman/aw5d-linux/main/bootstrap.sh | bash

Also added a CI installer smoke test (sandbox run with stubbed sudo/systemctl) so this can't regress.

v1.1.0 — friendlier & self-serviceable

Quality-of-life release. Everything since v1.0.0, all backward-compatible.

New

• aw5d-lcd command on your PATH — aw5d-lcd doctor, list, --help (installed to ~/.local/bin; override with AW5D_BIN_DIR).
• doctor — diagnoses a dark screen: device present? hidraw writable? sensors? Python version? service? aw5d-lcd on PATH? — each with a fix hint.
• aw5d-lcd self-update — a manual updater (fetch + reinstall + restart). Nothing auto-updates.
• One-line install: curl -fsSL https://raw.githubusercontent.com/claygorman/aw5d-linux/main/bootstrap.sh | bash — no reboot, no rpm-ostree layering on Bazzite/atomic.
• Configurable update interval via AW5D_INTERVAL (~/.config/aw5d-lcd.env), with a too-low warning + safe clamp.
• Installer preflight detects a Python 3.8+ interpreter and renders the launcher + systemd unit with it.
• Unit tests + CI — build_packet asserted byte-for-byte against the captured golden packet; a required check on PRs.
• A Justfile (just install/doctor/test/logs/...).

v1.0.0 — first light

First public release: drive the iBUYPOWER AW5/AW5D AIO cooler's round LCD natively from Linux — no Windows, no vendor software.

Highlights

• Dependency-free Python driver (aw5d_lcd.py, stdlib only); auto-detects the HID device and reads k10temp / /proc/stat / cpufreq.
• Stock CPU gauge over HID report 0x10 (~1 Hz): usage, exact MHz, temperature — validated against HWiNFO and the on-screen numbers. No handshake.
• systemd user service (linger) + udev rule + installer; configurable update interval (AW5D_INTERVAL).
• Full clean-room reverse-engineering writeup in RESEARCH.md.
