-# Onboarding + Config Protocol
-
-Purpose: shared onboarding + config surfaces across CLI, macOS app, and Web UI.
-
-## Components
-
-- Wizard engine (shared session + prompts + onboarding state).
-- CLI onboarding uses the same wizard flow as the UI clients.
-- Gateway RPC exposes wizard + config schema endpoints.
-- macOS onboarding uses the wizard step model.
-- Web UI renders config forms from JSON Schema + UI hints.
-
-## Gateway RPC
-
-- `wizard.start` params: `{ mode?: "local"|"remote", workspace?: string }`
-- `wizard.next` params: `{ sessionId, answer?: { stepId, value? } }`
-- `wizard.cancel` params: `{ sessionId }`
-- `wizard.status` params: `{ sessionId }`
-- `config.schema` params: `{}`
-
-Responses (shape)
-
-- Wizard: `{ sessionId, done, step?, status?, error? }`
-- Config schema: `{ schema, uiHints, version, generatedAt }`
-
-## UI Hints
-
-- `uiHints` keyed by path; optional metadata (label/help/group/order/advanced/sensitive/placeholder).
-- Sensitive fields render as password inputs; no redaction layer.
-- Unsupported schema nodes fall back to the raw JSON editor.
-
-## Notes
-
-- This doc is the single place to track protocol refactors for onboarding/config.
