Fix a Monorepo Root Makefile

Problem/Feature Description

A platform team manages a monorepo with multiple sub-projects, each with its own Makefile. The root Makefile orchestrates builds across all sub-projects. Recently, developers running make -j4 from the root reported corrupted build artifacts and cryptic error messages. The team lead suspects the root Makefile is not properly propagating build settings to sub-project builds. Additionally, one target that runs a multi-step shell script intermittently fails midway through but Make continues to the next step instead of aborting.

Review the root Makefile below, identify all issues contributing to these problems, produce a corrected version, and write a fix-notes.md explaining each change.

Output Specification

Produce:

• A corrected Makefile
• A fix-notes.md documenting each issue and the fix applied
