hotfix(deploy): install git in Lambda Dockerfile#160
Merged
Conversation
The Phase 2 Lambda deploy job has been failing on: ERROR: Cannot find command 'git' - do you have 'git' installed and in your PATH? The Lambda Python 3.12 base image (public.ecr.aws/lambda/python:3.12) doesn't ship with git, but the Dockerfile uses `pip install ... @ git+https://...` which requires it. Surfaced today when PR #159's post-merge Deploy fired against a fresh build (vs the prior in-flight image which had a cached install layer that masked the gap). Fix: same one-line microdnf install applied to alpha-engine-research Dockerfile after PR #105's lib-public flip. AL2023 minimal package manager; image-size impact ~25MB. Out of scope: the FromPlatformFlagConstDisallowed warning (line 1) about `--platform=linux/amd64` is a separate buildkit lint that doesn't block builds — leave for a follow-up. Test plan - [x] Diff parity with alpha-engine-research Dockerfile (same line) - [ ] Deploy workflow re-runs cleanly post-merge Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
The Phase 2 Lambda deploy job has been failing on:
```
ERROR: Cannot find command 'git' - do you have 'git' installed and in your PATH?
```
The Lambda Python 3.12 base image doesn't ship with git, but the Dockerfile uses `pip install ... @ git+https://...` for alpha-engine-lib. Surfaced today by PR #159's post-merge Deploy run against a fresh build.
Fix
Adds `RUN microdnf install -y git && microdnf clean all` before the pip install. Same one-line fix applied to alpha-engine-research Dockerfile after PR #105's lib-public flip exposed the same gap there.

Out of scope
The `FromPlatformFlagConstDisallowed` warning on line 1 (
--platform=linux/amd64) is a separate buildkit lint — doesn't block builds, leave for follow-up.🤖 Generated with Claude Code
