 # Ordinary-auction time limit
 
+## Sequential Richese auctions — 29 October 2026
+
+**Prototyped / Partial.** Fresh Once Around cache/Black Market lots and normal
+Black Market lots use the same trusted ten-second room clock as ordinary
+auctions. Expiry performs the actual Richese pass. A binding Once Around
+Truthtrance Yes instead submits its lowest compatible funded bid, retaining
+the existing provisional online convention. Truthtrance and other decisions
+hold the remaining budget; changing a later bidder's order does not give the
+current bidder more time. Room pause/control fences, stale-action checks and
+the existing bounded worker apply. The public countdown does not expose the
+concealed Black Market card.
+
+The publisher's Basic ten-second rule and the authorized Advanced revision
+physical p. 8 / printed p. 6 govern ordinary bidding. Applying that limit to
+Once Around is a provisional online interpretation, not a separate publisher
+ruling. Silent auctions stay untimed; previously open unstamped special lots
+retain their saved behavior. Real Basic cache and Advanced Black Market tests,
+display and isolated trusted-room cases plus one authenticated HTTP QA room
+cover this slice. Complete modes, other auction interactions and final deployed
+acceptance remain open.
