Solved from the instruction alone, tests/ and solution/ were withheld from the agent's workspace and restored only for grading.
Reward = tests/test.sh exit code (0 → resolved); the classification below is post-hoc and cannot change it.
Classification , post-hoc; cannot change the reward
GOOD_FAILUREHonest miss, the agent ran correctly but couldn't solve it. Expected for a hard task; the task is sound.
SubtypeImplementation Bugs
EvidenceTest stdout shows: "SCRIPT ERROR: Parse Error: The variable type is being inferred from a Variant value, so it will be typed as Variant. (Warning treated as error.) at: GDScript::reload (res://scripts/player_body.gd:46)" followed by "ERROR: Failed to load script 'res://scripts/player_body.gd' with error 'Parse error'". The agent's code contains a type inference issue that Godot treats as an error, preventing the script from loading and blocking verification of the required exports.
Root causeThe agent attempted to implement the camera shake rig but made a GDScript type inference error at line 46 of player_body.gd that prevented the script from parsing. This is a common programming mistake on a complex task requiring precise type annotations in GDScript, not a task specification issue.
RecommendationN/A - task is fine

Reproduce this trial: git checkout 2f94510 && PYTHONPATH=src python3 scripts/build_site.py , then open trial/trial_27a232b7de544d21. Re-running the agent live requires EVAL_PLATFORM_ENABLE_OAUTH_SMOKE=1 and is non-deterministic.
