• attic_list_markets

  List the four Attic collector markets (rare coins, sports cards, collector cars, fine art) with Headlines, Beyond, and Creators page URLs on atticcapital.com. Use this when you need the canonical page to link, not a top-5 roster.

  List shows, auctions, and other gatherings on the Attic calendar. Optional market filter. Public. This is the calendar, not the Gatherings pillar of the weekly report (use attic_get_market_report with pillar gatherings for that top 5).

• attic_get_changes

  Ledger of roster and gathering moves since the prior weekly cut. Use this for 'what changed', rank moves, names that entered or left a top 5. Optional since (YYYY-MM-DD), market, and layer. layer=beyond is Attic Beyond. An empty list means the rosters did not move.
