Pin alpha-engine-lib to v0.1.1 for Python 3.9 compat#29
Merged
Conversation
v0.1.0 had requires-python = >=3.11, which caused pip to silently skip the install on EC2 (running Python 3.9) and surfaced as ModuleNotFoundError on weekly_collector import. v0.1.1 relaxes the floor to >=3.9. No runtime code changes needed on the consumer side — only the pinned tag. Verified locally: tests pass, import resolves from the v0.1.1 tag. Next step: re-run manual DailyData on EC2 — pip install should now succeed. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
One-line pin bump from v0.1.0 → v0.1.1 in requirements.txt. v0.1.1 relaxes the lib's Python floor to `>=3.9` so it installs on the EC2 micro instance. No code change needed on this side.
Why
First manual EC2 test after #28 merged failed with `ModuleNotFoundError: No module named 'alpha_engine_lib'`. Root cause: v0.1.0 declared `requires-python = >=3.11`, and EC2 runs 3.9 — pip silently skipped the install.
