The catalogue had grown a barracks, wartime shelters, an air-defense battery, a warm-water port and a shipyard, but only as data: infantry still trained without a barracks, shelters did nothing, and an airport was just an airbase. Each building now names the rule it grants with a `mechanic` id, so the simulation and the city panel describe the same thing without magic strings. - Barracks and shipyards open one more production line each. A line sticks to one entry at full rate, so two units build at once rather than the head absorbing every line; the base behaviour (one queue, overflow carrying into the next entry) is unchanged. - Wartime shelters keep 10% of civilians per level safe from bombardment and are very hard to knock down, and ranged fire can now destroy a building level outright, with no refund. Each building rolls its own chance per point of damage, from a generator seeded off the world so a bombardment replays identically. - Air defense fires one volley at a hostile aircraft the moment it enters the city tile, scaled by its level; a plane shot down never drops its bombs. - A port adds 1000 GDP per capita per level, per adjacent sea tile, to every tile in its region. - An airport draws a daily trickle of people from every other airport city in the world, scaled by the destination's level. - Wired the new effects into the city panel and taught the repeatable Industrial Automation to satisfy other technologies' prerequisites. Added tests for each mechanic and for the parallel lines.
