What it emitted: - After activation /llms.txt returned 404; the wpseo option enable\_llms\_txt was false. - After the option was set to true /llms.txt returned 200 text/plain with an H1, a Categories section and an Optional section holding the sitemap index; the first line began with a byte-order mark. - The home page HTML did not link /llms.txt. - Yoast added a JSON-LD schema graph (class yoast-schema-graph) to the pages and its own robots.txt block with a Sitemap line. - No markdown negotiation.
