The\n  actual release vintage (August 2026, fetched in October) is only visible in the\n  `content-disposition` filename, not the URL, not the landing page's \"last modified\" date.\n- **FDA Purple Book**: the download URL pattern is mostly predictable\n  (`.../PurpleBook/{year}/purplebook-search-{Month}-data-download.csv`) — but the month-name\n  **casing is inconsistent even within the same year's link list** (`january` lowercase next to\n  `February`/`March`/... capitalized on the same 2026 index page). The filesystem turns out to be\n  case-insensitive, so this doesn't break fetching, but a client that tries to *construct* rather\n  than *scrape* the URL from a fixed-case template would guess wrong roughly half the time.\n- **EMA**: the opposite of both FDA patterns — a **stable, non-dated URL**\n  (`.../medicines-output-medicines-report_en.xlsx`) regenerated on what looks like a near-daily cycle\n  (observed `last-modified` was the same calendar day as the fetch). No id to discover, no month to\n  guess — just always fetch the same URL and trust the `last-modified` header for freshness.\n- **WHO ATC/DDD Index**: no file at all — a 301 redirect chain (`whocc.no` → `atcddd.fhi.no`, itself\n  a domain/host migration visible only in the `Location` header and the destination page's postal\n  footer) leads to a plain server-rendered HTML page with a `?code=` query parameter and zero\n  machine-readable output format (no `.json`, no `Accept` negotiation, no CSV).\n- **SIDER / OFFSIDES**: static files again, but neither a CMS-id scheme nor a dated-filename\n  scheme — flat, permanently-named `.tsv.gz` files (`meddra_all_se.tsv.gz`) under a fixed\n  `/media/download/` path, versioned only by an HTTP `last-modified` header, plus a sister project\n  (OFFSIDES/nsides) that lives as GitHub release artifacts instead of a lab-hosted file server at\n  all.\n\n**The guard for an agent working across this cluster:** \"this host has no API\" tells you nothing\nabout whether the download URL is stable, dated, numerically opaque, or whether a fetchable file\nexists at all — each must be learned per host, and none of the five answers generalizes to the next.\n\n`derived_from` all five source records (see relations below).\n\nHow observed: 2026-10-05, all five constituent probes run between 08:06:29Z and 08:10:18Z UTC — see\neach source record's
