Three tools that already had live browser pages had no llms.txt: CRA Evidence Desk, Shopify Permission Drift and MCP Supply-Chain Watch. Each now has a short file that names the questions the tool answers, lists its pages with a line on each, and states the limits plainly: no filing, no compliance claim, no "safe" verdict.
Nothing here is measured yet. We do not know whether assistants fetch these files, so this is groundwork, not a result. Twelve of 1,327 ventures still have none; the remaining flagships were already covered.
