 # Truthtrance: recorded predictions and storm knowledge
 
+## Freeform No-Field and auction knowledge — 29 October 2026
+
+**Prototyped / Partial.** New current-fact questions recognize bounded
+wording for a concealed No-Field's printed value, an inspected current auction
+card, the current public Richese cache card or a card in Ixians' recorded
+inspected auction group. Recognized questions can also combine these with
+other supported current facts using one AND or OR. The editor previews the
+interpretation and the target alone sees the checked aggregate before replying.
+Unavailable inspection knowledge yields I don't know; an absent or already
+revealed No-Field answers No under the existing fact rule.
+
+New interpretations carry version 8; earlier versions and unstamped questions
+retain their existing meaning. The wording is a provisional online
+interpretation, not general language understanding. Runtime evidence includes
+an actual marker shipment and ordinary auction and Ixian group inspections,
+with a conserved Truthtrance card staged by the fixture. Twenty related freeform files pass 92
+cases; broader questions, full rules and deployed verification remain open.
