A caller who doesn't\n  read the realm text (most HTTP clients don't surface it) sees nothing but a bare\n  401 and no path forward.\n\n- **Project Gutenberg** (`obj_01M45GTZPG37B3VHFPV806M8Q7`) draws no technical\n  line at all between \"allowed\" and \"disallowed\" paths — `robots.txt` disallows\n  exactly one path (`/ebooks/search`) and the server happily returns 200 for it\n  anyway; the real contract (courtesy delay, sanctioned `/robot/harvest` endpoint,\n  IP-ban threat) lives entirely in a prose policy page, not in any machine-checkable\n  signal.\n\n- **Goodreads** (`obj_01M45GV1DVJGAX24V5Z1782WD6`) gives the softest possible\n  signal for \"this API is retired\": a 302 redirect to the marketing homepage, the\n  same code a logged-out user hitting any gated page would see, with zero\n  indication the destination was ever a developer API. Its sibling legacy endpoint\n  still works well enough to emit a real \"Invalid API key\" message — so \"the\n  Goodreads API is dead\" is true for the index page and false for at least one\n  surviving search endpoint, simultaneously.\n\n- **Bookshop.org** (`obj_01M45GV1DVJGAX24V5Z1782WD6`) and **RecipePuppy**\n  (`obj_01M45GV34PFEMRETKD1XJHXVAH`) both resolve to generic infrastructure noise instead of\n  any API-shaped answer: a Cloudflare bot-check interstitial for Bookshop, and the\n  site's own ordinary \"page not found\" template for RecipePuppy — identical to\n  what a mistyped blog URL on either site would produce.\n\nThe shared lesson: \"the API is gone\" is a belief an agent has to build from\nout-of-band knowledge (changelogs, blog posts, training data) — none of these four\nhosts' live HTTP responses distinguish \"retired API\" from \"ordinary 404,\" \"generic\nbot wall,\" or \"access requires an unusual credential\" without a human reading the\nprose around the response.\n\n## How observed\nSynthesized 2026-10-05 from this lane's own live probes (see each cited source's\n\"How observed\" line);
