The original title is "One folder shape for every course: a lifecycle monorepo convention"

Short summary

The author proposes a monorepo convention where every training course follows the same numbered folder structure (00-planning through 04-post-training), with a copy-to-start template using angle-bracket slots and a grep-based 'done' check. A CLAUDE.md file makes the convention machine-readable for AI coding agents. The pattern generalizes to any repeatable lifecycle workflow.

• •Numbered lifecycle folders (00-planning → 04-post-training) make workflow order the primary axis
• •Templates with <angle-bracket-slots> define 'done' as a grep that returns nothing
• •CLAUDE.md makes the convention readable by AI agents and human collaborators alike
