HWall 1.0.3

New features

• Added APERF/MPERF-derived average and per-logical-CPU effective clocks on supported x86 systems.
• Added explicit current, stale, and unavailable states for live sensor readings, plus an Offline state for present logical CPUs that are not online. Last-known stale values remain visible with dimmed styling and their last successful update time.
• Added a persisted GTK theme preference with System, Light, and Dark choices.

Bug fixes

• Prevented failed or disappeared sensor readings from being counted as fresh history, statistics, or log samples.
• Suspended active alert evaluation while sensor data is stale, unavailable, faulted, or missing, without reporting missing data as a recovery.
• Corrected realtime CLI and terminal-monitor scheduling so collection and rendering time no longer extend the requested sampling interval.
• Prevented delayed realtime refresh requests from accumulating and running as stale queued samples.

Improvements

• Reduced hidden-window CPU work by keeping collection, alerts, history, and logging active while deferring invisible GTK view projection until the window is shown again.
• Updated only the active Sensors or Hardware presentation on each sample and reused the existing stable-ID row synchronization instead of rebuilding both views.
• Reduced the GTK event polling cadence from roughly 60 Hz to 20 Hz while retaining responsive tray and worker handling.
• Added a native Save As flow for history export with a timestamped filename and remembered export directory. Formatting and writing run on a background worker so collection, recording, and the GTK main thread continue uninterrupted.
• Removed the continuously increasing general sample counter from the main status bar while retaining per-sensor sample counts in Details.
• Made fast snapshot merging freshness-aware and stopped transient collector warnings from accumulating across refreshes.
• Isolated SMART and NVMe health collection from normal telemetry, so slow commands and interactive administrator authorization do not interrupt sensors such as nvidia-smi.
• Added bounded execution for noninteractive helper commands: 10 seconds for ordinary hardware helpers and 60 seconds for storage-health helpers.
• Restricted elevated helper lookup to standard system executable directories while retaining normal PATH lookup for unprivileged commands.
• Standardized human-readable clock values
