Lux Partners Limited is not the entity behind this work. Every place the old name stood — copyright lines, site footers, brand config, legal and compliance text — now names the company that actually holds it. lux.fund is the exception and is not renamed to match: that site belongs to Lux Assets Management LLC, a different company, and it says so. Two kinds of line were left for a person rather than rewritten. A dated news item recording that Lux Partners Limited was established in the Isle of Man is a historical fact, and renaming it would falsify the record. And a sentence asserting that the company is domiciled in the Isle of Man is a claim about a jurisdiction, not a name — an Inc or an LLC is not an Isle of Man company, so swapping the name there would assert something untrue.
