# S5 — init: bootstrap the ADR system - **Fixture:** `legacy-project` · **Skill:** `init` - **Checker asserts:** `docs/adr/README.md` created with generated markers, `.os-adr` gitignored, `DECISIONS.md` byte-identical. (Suggesting `/os-adr:migrate` for the legacy log is correct per the skill but not machine-scored.) ## Task (give verbatim to the model under test) Set up the ADR system in this project.
