Correctness and safety

• assault success chance and role coverage are locked at departure
• active teams are excluded from colony production and Living Colony visuals
• ready reports apply rewards and progression exactly once
• invalid commander sequences are reconstructed from real defeated predecessors
• pressure, timestamps, history and operation state are bounded during normalization
• inventory capacity is checked before item-bearing reports are claimed
• Save Schema 38 and the browser storage key remain unchanged
