✨ What's New

Scheduling

• Staggered engine triggers (WS 0s / Standby +10s / FileCache +20s / Maint +30s) — the all-at-once burst at cycle start is gone, so the service no longer spikes a CPU core to 70%+ and Osmium's EcoQoS stops flapping every minute
• WorkingSet tiers reworked — below 50% memory only a baseline 1 run/min (trimmed pages are read back immediately at low occupancy, so aggressive cleaning had no net gain), stepping up to 5 runs/min at the 50/70/85/95% tiers

Sampling fixes

• CPU usage fixed — GetSystemTimes kernel time already includes idle, the old formula double-counted it and idle machines always reported a constant ~51%
• Disk activity fixed — newer Windows 11 builds no longer expose the % Active Time counter, which left the sampling silently dead at 0; the counter now uses % Disk Time and init failures log a WARN instead of failing silently

Logging

• Per-cycle summary line (Cycle: Mem a% → b% (ΔMB, x%↓)) — the whole-cycle net effect is now visible next to the per-engine Used / Standby lines; the Used line itself keeps only the MB delta

Identity & licensing

• Binary renamed scandium_svc64.exe → scandium_svc.exe — the installer transparently migrates existing installations (legacy service registration, App Paths key and leftover files are cleaned up)
• Build script renamed BUILD.ps1 → .release.ps1
• Relicensed under Apache License 2.0 — see LICENSE and NOTICE
