Connecting to the bigger picture

This loader fills the project_instructions slot Chapter 3 left open, and because that slot sits in the cached prefix, Chapter 5's caching rules apply (keep it stable). The file-based scratchpad idea is the same external-storage move Chapter 5 listed, and it is exactly how Manus's todo.md and file memory work (Chapter 14). The two-tier, git-committed pattern is the portability pillar that Chapter 16 leans on for team rollouts. In the capstone, MemoryLoader runs once at startup and its output rides in every prompt.
