Product hardening for scans that span a laptop sleep/wake cycle: a mid-scan sleep defers all disk-heavy phases into one burst on wake (competing with the user right as they sit down), and monotonic phase durations understate the wall-clock span (minutes of measured work across an hours-long window).
PRIO_DARWIN_BG(Time Machine tier), Linux nice 19 + best-effort ionice 7 (deliberately not the starvable idle class), Windows below-normal class + background IO/memory mode. All tiers are throttled-but-guaranteed-progress; existing phase budgets and the 60m scan deadline bound the worst case. Escape hatch:STEPSEC_DISABLE_BACKGROUND_PRIORITY=1. Communityscanstays foreground.slept_ms(wall-vs-monotonic divergence, 60s floor for NTP jitter) flows through run-status heartbeats and the final payload; logs "system slept ~Xm during phase X" plus a run-summary note. Durations stay monotonic; the scan is never aborted.Verified: full
