code-tour

Write a human reading path through a codebase or a just-finished build — one tour file with the stack, file-role rules, an ordered reading path along one real user-visible flow, safe hands-on experiments, run steps and a glossary, every path cited and checked. The source tree is never modified. NOT for adding comments to source files (the tour lives outside the code), NOT a code review or completion check (that is code-reviewer / /verify-completion), and NOT the org-wide repo onboarding guide (that is ONBOARDING.md).
