Missing src/__init__.py (implicit namespace package)

[DeFiVC]

What

All sub-packages (routes/, services/, knowledge/, prompts/, models/) have __init__.py files, but src/ itself does not.

Why

The code works via Python 3's implicit namespace packages, but this is fragile: some tools (pytest's --import-mode=importlib, certain IDE inspectors, mypy in strict mode) may fail to resolve from src.config import settings. The scripts/build_index.py and scripts/test_generation.py work around this with sys.path.insert(0, ...), which further confirms the packaging issue.

Scope

• Add src/__init__.py

Acceptance Criteria

• src/__init__.py exists
• Tools can resolve from src.config import settings without workarounds

Technical Context

• File: src/ directory
