Everything lived in one flat directory, so a diff gave no clue what area it touched and finding the file you wanted meant knowing its exact name. Twelve folders now, grouped by what a thing IS rather than what type it is - a vessel's definition, its component scenes and its upgrade resources sit together, because that is the set you read when you change one of them. buildings core controllers enemies logistics planets resources shaders surface ui vessels vfx world 332 files moved and every res:// reference rewritten - 306 files touched, including the autoload and main-scene paths in project.godot. Nothing renamed: this is purely where files sit, so the diff is a pile of pure moves and no behaviour is buried in it. ui_theme.tres, icon.svg and web_shell.html stay at the root, where Godot and the export preset expect them. Verified three ways, because a suite alone would not have caught all of it: the full 117 pass, the web export builds clean, and the game renders. The export is why that matters. The FIRST export after the move failed with "Attempt to open script 'res://GameState.gd'" - the old path - while project.godot on disk plainly said res://core/GameState.gd. That is this project's documented Android FUSE mtime trap: Godot served a cached copy of a file whose content had changed. A `touch` fixed it. Nothing in the test suite would have found that, because the suite runs from a copy on a native filesystem - the one place the bug cannot happen. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# Regression test for a permanently-drifting camera. GameController followed
|
|
# the fleet with an exponential lerp and no snap threshold, so it approached
|
|
# the fleet centroid asymptotically and NEVER arrived - the camera kept
|
|
# moving by a fraction of a pixel every single frame, forever, even with the
|
|
# fleet completely stationary. That kept the background shaders' camera_pos
|
|
# uniform changing every frame, which made screen tearing permanently visible
|
|
# as horizontal bands of the background sliding sideways against each other.
|
|
#
|
|
# Verifies the camera reaches an EXACTLY stable position (bit-identical
|
|
# frame to frame) once the fleet has stopped, not merely a nearly-stable one.
