# Journey: Storage Stage 3d of the guided journey. Configure storage buckets/ACLs from the plan. ## When to use - Dispatched by `journey` when `current_stage: storage`. - Directly via `/butterbase-skills:journey-storage`. - Skipped (annotated `(n/a)`) if the plan has no Storage section. ## 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 Storage section. - `docs/butterbase/00-state.md` — for `app_id`. ## Procedure 0. **Refresh docs.** Call `butterbase_docs` with `topic: "storage"`. For presigned URL patterns, also WebFetch `https://docs.butterbase.ai/storage`. Skip if cache is fresh. 1. Read the Storage section of `02-plan.md`. Print it back: `"About to configure storage: <buckets>. Proceed?"`. Wait for `yes`. 2. Invoke `butterbase-skills:storage` via the Skill tool, passing the Storage plan and `app_id`. The wrapped skill calls `manage_storage action: update_config` per bucket (visibility, max object size). 3. Smoke: request an upload URL via `manage_storage action: upload_url` and a matching `download_url` to confirm presigned URL minting works. 4. Append one line to `docs/butterbase/04-build-log.md`: `<ISO timestamp> storage manage_storage ok` 5. Tick `- [x] storage` in `00-state.md`, set `current_stage:` to the next unchecked stage. 6. Ret...
