Root + Impact

Description

Documentation specifies a fixed 3-day auction period with an endAuction() function. In practice, the contract only provides settleAuction(), which uses a rolling 15-minute extension mechanism. There is no fixed 3-day expiry, and the named function endAuction() is absent.

Risk

Impact:

Low — functional mismatch between spec and code. Could cause confusion for users and integrators expecting fixed 3-day auctions.

Recommended Mitigation

Either (1) update documentation to reflect the rolling auction design, or (2) implement a hard 3-day maximum duration in addition to the current anti-sniping logic.
