Data structures and enums

Auction

getAuction(uint256) returns leaderSubmissionId, leaderBid, winnerSubmissionId, winningBid and finalized. A zero leader ID means there is no current leader. Winner fields are meaningful only after finalization.

Submission

getSubmission(uint256) returns auctionId, submitter, contentHash, bidAmount and refundWithdrawn. Authored strings are emitted by SubmissionCreated and bound by contentHash; they are not returned by this read.

Record

getRecord(uint256) returns kind, submissionId, imageURI, title and description. On Robinhood Chain, kind 2 represents a winning Record and kind 3 represents an Empty Record.

Identifier relationships

Auction ID, Record ID and Tablet token ID identify the same represented day. Submission IDs use their own increasing counter. Auction 1 represents the Tokyo day containing initialization; later IDs advance one Tokyo day at a time.
