Changelog

Version: 0.9.0
Date: 31. 08. 2026
  Major Features:
    - Added recoverable factory incidents, circuit-native monitoring, alarm consoles, recovery playbooks, fault domains, reliability objectives, and the Incident Operations Center.
    - Added controlled experiments and deterministic suites with assertions, safety reservations, schedules, baselines, portable challenges, and exact restoration evidence.
    - Added the command-free Reliability Lab scenario covering monitoring, recovery, redundancy, capacity degradation, telemetry integrity, and staged restoration.
  Features:
    - Added dependency architecture, conservative risk analysis, provider-loss drills, readiness policies, and committed readiness assessment history.
    - Added circuit and remote interfaces for automation, inspection, controlled experiments, and integration discovery.
  Balancing:
    - Ambient random incidents are disabled and disarmed by default; difficulty changes pressure only after explicit opt-in.
  Changes:
    - World mutations capture prior state and compare before restoration. Ownership conflicts fail closed and remain visible as intervention evidence.
  Info:
    - Added support for Factorio 2.0 with Space Age as an optional dependency.
    - This is the first public preview. Saves created with unreleased 0.0.0 development snapshots are not supported for upgrade.
