Forgejo #11: buildings the player has placed now appear on the world map. They are placed freely in space rather than tied to a chunk, so they get their own pass in WorldMapContent._draw() rather than riding along with the chunk markers. Each type has its own shape and colour, mirroring Building.gd's constants so a marker reads as the same building you built. Forgejo #9: a planet with an extractor built on it now shows it, in both places you look at a planet - an amber derrick on its outline in space, and a matching badge on its world-map marker. The extractor lives on PlanetSurface.tscn, a scene you are not looking at from space, so an already-mined planet was otherwise indistinguishable from an untouched one until you landed on it. The positioning steps are factored out (building_markers(), chunk_has_extractor_badge(), extractor_derrick_tip()) so headless tests can assert on them - --headless has no GPU and draws no pixels, so there is nothing to check in _draw() itself. Both features were also rendered for real via tests/screenshot.sh and looked at. extractor_derrick_tip() exists because the first version of the "derrick is not buried inside the planet" check measured the furthest of all four derrick points, which passes a derrick pointing straight into the ground: the base corners sit a half-width off the rim vertex and clear the outline on their own. Mutation-testing caught it. screenshot.sh now clears a stale /tmp/.X99-lock. A run killed mid-screenshot leaves it behind and Xvfb then refuses :99, which resurfaces later as Godot's misleading "X11 Display is not available".
