Auction House update

Auction House

• Accessible via the sidebar button inside the Market GUI
• Players can list any item not already in the market as an auction or Buy It Now (BIN) listing
• Five listing durations available: 1 h, 6 h, 12 h, 24 h, 48 h
• Configurable listing fee (% of price) deducted at creation — non-refundable even on cancellation
• Configurable maximum listing price guard to prevent overflow and unreasonable listings
• Open auctions: bids must exceed the current top bid by at least 1% (always ≥ 1 unit)
• BIN listings: first click arms a 3-second confirmation window; second click executes
• Anti-snipe: bids placed within the last 2 minutes of an auction extend it by 2 minutes (configurable)
• Previous top bidder refunded to their escrow immediately when outbid; notified if online
• On auction end: item goes to winner's escrow, proceeds go to seller's escrow
• Auctions that expire while the server is offline are finalized automatically on next start
• Hard cap of 20 active listings per player
• Escrow system: all money and items held in persistent escrow — nothing is lost if the server crashes between an auction ending and the player claiming
• Players claim items and currency via a dedicated "Claims" button
• Finalized auction records pruned automatically every 5 minutes (records kept for 30 minutes post-expiry)

New admin commands

• /jakeseconomy market setlock <item> <lockId> — change an item's achievement lock live without editing JSON
• /jakeseconomy market setprice gains an optional [achievementLock] argument
