# Add __init__.py to Namespace Packages

Add `__init__.py` files to implicit namespace packages to prevent import hijacking and ensure correct package resolution.

## Problem Statement

Both Security Sentinel (INP001) and Kieran Python Reviewer identified missing `__init__.py` files. While Python 3 supports implicit namespace packages, omitting `__init__.py` in standard packages can lead to ambiguity and potential security risks (import hijacking).

## Findings

- **Issue:** Missing `__init__.py` files.
- **Impact:** Security/Reliability. INP001 warning.

## Proposed Solutions

### Option 1: Add Empty __init__.py

**Approach:** Create empty `__init__.py` files in all directory levels that function as packages.

**Pros:**
- Explicitly defines packages.
- Resolves INP001.

**Cons:**
- Adds file clutter (minor).

## Recommended Action

**To be filled during triage.**

## Technical Details

**Likely locations:**
- `src/helia` (check if present)
- Subdirectories in `src/helia` where they are missing.

## Resources

- **Source:** Security Sentinel / Kieran Python Reviewer

## Acceptance Criteria

- [ ] `__init__.py` files added to all relevant source directories.
- [ ] Package imports verify correctly.
