## Root Cause

Two top-level requirements transitively require incompatible versions of a shared dependency.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.x | active | — | — |

## Workarounds

1. **** (85% success)
   ```
   pip install pip-tools
pip-compile requirements.in
pip-sync
   ```
2. **** (80% success)
   ```
   pip install "foo>=1.0,<2" "bar>=2,<3"
   ```

## Dead Ends

- **** — Forces installation but leaves a broken dependency graph; imports may fail at runtime. (75% fail)
- **** — Skips dependencies entirely, causing ModuleNotFoundError later. (80% fail)
