# Journey: Schema Stage 3a of the guided journey. Apply the declarative table definitions from the plan. ## When to use - Dispatched by `journey` when `current_stage: schema`. - Directly via `/butterbase-skills:journey-schema`. ## Preflight If `docs/butterbase/03-preflight.md` is missing, older than 24 hours, or `00-state.md` has `app_id: null`, invoke `butterbase-skills:journey-preflight` first. Wait for it to return successfully before proceeding. ## Inputs - `docs/butterbase/02-plan.md` — the Tables section. - `docs/butterbase/00-state.md` — for `app_id`, `hackathon_mode`. ## Procedure 0. **Refresh docs.** Call `butterbase_docs` with `topic: "schema"`.

Skip this step if `docs/butterbase/03b-docs-cache.md` was written less than 30 minutes ago and already covers `schema`. 1. Read the Tables section of `02-plan.md`. Print it back: `"About to apply schema: <N tables>. Proceed?"`. Wait for `yes`. 2. Invoke `butterbase-skills:schema-design` via the Skill tool, passing the Tables section and `app_id`. The wrapped skill will build the declarative schema, dry-run it with `manage_schema action: dry_run`, then apply with `action: apply` after user approval of the diff. 3. After it returns, optionally run a sanity `manage_schema action: get` and show the user the live shape. 4. **Hackathon mode only:** if `00-state.md` has `hackatho...
