Toggle cloaking device (Requires a cloaking device module or a ship with an integrated cloak. When cloaked, passive views (get_nearby, ship counts, observation, travel arrival) never list you; only an active scan whose power exceeds your total scan defense can resolve you. A battle cannot hold a cloaked ship: you cannot engage a cloak while in a battle (in_battle), and attacking or engaging drops it. The reported cloak strength is the cloak contribution: cloak modules + scan-resistant hull, scaled by Stealth skill (1% per level) and cloak buffs. Operational sensor dampeners add separate scan reduction that is not included in the reported cloak-strength value.)
