It owns the workflow; do not recreate it here or load the command catalog speculatively.\nLoad `references/experience-design.md` at `../noodle-seed/references/experience-design.md` only when the playbook or observed evidence names that concern.\nLoad `references/widgets-and-apps.md` at `../noodle-seed/references/widgets-and-apps.md` only when the playbook or observed evidence names that concern.\n\n## Verification evidence\n\nThe App passes validation, local smoke, app checks, and the requested preview or host evidence level.\n\n## Recovery paths\n\nDistinguish data-contract, widget-runtime, rendering, host, and deployment failures.\n\n## Stop conditions\n\nStop before deployment or publication unless that distinct outcome was requested.\n\n## Handoff contract\n\nPass the selected outcome, explicit target, changed files, commands run, passing evidence, first unproven evidence layer, sanitized failure, remaining authority, and exact next action. The receiving skill continues from that layer; do not restart discovery or discard prior proof.\n"
