The ideas to retain
Five objects worth naming separately
Before designing concurrency or security, make the vocabulary explicit.
1. Repository and base revision
The repository contains history, refs, Git objects, configuration, and one or more working trees. An agentic task also needs an identifiable base revision, normally a commit SHA.
2. Context view
The model does not automatically receive every byte in the repository. The harness selects, or lets the model retrieve, files, symbols, instructions, diffs, logs, and history.
