QC #3: modules/world_sync/__init__.py made the module REPO ROOT a Python package,
violating module-development-spec (mymodule/ = repo root, mymodule/mymodule/ = package).
Host wiring verified to resolve to the INNER package, so the root forwarding table is
dead weight:
- apps/scense/app/scense.py:50 from world_sync.init import load_world_sync
- apps/yuanjing/app/yuanjing.py:66 __import__(f'{module}.init', ...)
Both parse world_sync/init.py with sys.path=<repo root>; neither uses the root package.
Re-verified after deletion: py_compile OK for all .py; import closure 0-broken from both
sys.path=modules/ and sys.path=modules/world_sync/ (import world_sync /
from world_sync.init import load_world_sync / 4 contract APIs; __all__ len=62 MISSING=[]).
pyproject packages.find needs no tightening: with the root package gone,
where=['.'] include=['world_sync*'] discovers exactly one package.
Unrelated pre-existing WIP scripts/validate_models_json.py (M11b-2b-A) intentionally
excluded from this commit via pathspec.
