Hybrid auction
An English auction with a hidden reserve that gets revealed once bidding crosses a threshold percentage of (reserve − starting). Combines reserve secrecy with bidder confidence.
Why it exists
Pure-reserve auctions sometimes end with no winner because no one bid enough. Hybrid solves that by telling bidders ‘you’ve reached 70% of the reserve’ so they know to push the rest.

The reveal_reserve_at_percent field on the Auction model controls when the reveal kicks in (0 = never).
