Actuator tiers must be per-agent-window: scale absolute gates (HARD_NUDGE_K/HARD_COMPACT_K, quarantine) by each agent's own CLAUDE_CODE_AUTO_COMPACT_WINDOW instead of assuming one fleet window

Measured on lezama 2026-08-16: four agents raised to 400k window against global absolute tiers produced 17 quarantine escalations at ctx 251k-358k in 7 days, with no dedup on quarantine. Same defect will hit mars the moment its cap is raised. Percent-only and token-only gates each have a hole (percent-only lets a 1M agent sit on 450k under every gate; token-only fires far too early on a big window), so the fix is to SCALE the absolute tiers per window, not delete them. Requires resolving each agent's own window (per-agent settings.json overrides the fleet default) and caching it, since a settings change only takes effect on relaunch.
