Retraining from scratch removes the constraint that blocked these: the existing checkpoints in Game/bots/promoted/ no longer need byte-identical geometry. - Fix the goal aperture constants (were 1.85/1.65, now match objects/goal.tscn's actual sensor exactly at 1.75/1.5) so a ball crossing the visible edge can't fail to score. - Cut a real navigable hole in each end wall's collision (_build_end_wall_colliders), replacing the previous solid box — the ball now genuinely enters the net instead of triggering the sensor a hair before hitting a solid wall. Correct for both FLOOR and ELEVATED goal modes via _goal_surround_bounds. A separate, slightly wider GOAL_VISUAL_APERTURE_* pair keeps the collision hole exact while still giving goal.gd's bezel/rim frame clearance to be seen against the hull cut. - Resize the play volume 1.5x (INNER_HALF_X/Z/HEIGHT 12/18/12 -> 18/27/18) to comfortably fit a 5v5 roster: updates every hand-authored literal in arena_boundary.tscn/arena_base.tscn/the elevated arena variants that doesn't derive from those constants, adds 5 spawn markers per team, and rescales ship_observations.gd's normalization scales and arena_02's cosmetic decoration/nebula-dust shader uniforms to match. - Bake the ~170 runtime-generated CollisionShape3D nodes into the scene via a new bake_colliders()/tools/bake_arena_boundary.gd instead of rebuilding them on every load — a real load-time cost repeated in every parallel headless training env. Colliders must be direct children of the StaticBody3D to register at all, so bake_colliders() parents them onto self and tags them with a group for idempotent re-baking, rather than grouping them under an intermediate container node. _ready() self-heals: it skips regenerating only when an existing bake's goal_mode metadata matches the current one, so the FLOOR-mode bake in the shared scene is never silently reused by an ELEVATED arena variant.
