- Remove the authless "sole connected phone" fallback and SB_REQUIRE_MCP_AUTH: an unauthenticated request no longer reaches whichever phone is online alone. - Mcp-Session-Id is no longer a credential; the Bearer token is checked on every request (MCP auth spec). - Refresh tokens live 90 days (was 30, equal to the access token, so they were always dead when first needed). - A rejected refresh no longer counts toward the IP ban: a client with an expired token was retrying into a self-renewing ban on its own IP. - 401s carry the RFC 9728 WWW-Authenticate discovery header.
