Documentation

README

Excerpt

Build Executor

Controls the implementation phase. Uses execution-contract.md as the workflow authority.

Required Inputs

For Full or legacy Hotfix, read execution-contract.md, tasks.md, relevant specs/, and relevant design.md. Quick, direct incident Hotfix, and Tweak require only their receipt, request boundary, changed files, and verification command.

Check workflow mode and receipt first. Tweak → direct edit mode. Quick or a valid direct incident Hotfix → Direct Quick and Hotfix. Full or legacy Hotfix → standard contract-first discipline.

This is the opening of the README. Read the full README on GitHub.
