Task 3: Anti-Snipe Implementation - Completion Checklist

✅ Implementation Requirements

Core Functionality

  • Extended AuctionConfig struct with 4 new fields

    • extension_window: u64
    • extension_amount: u64
    • max_extensions: u32
    • extensions_count: u32

  • Updated init_auction() signature

    • Added extension_window parameter
    • Added extension_amount parameter
    • Added max_extensions parameter
    • Initialize extensions_count to 0

  • Implemented anti-snipe logic in place_bid()

    • Late bid detection (now >= threshold && now < end_time)
    • Extension window threshold calculation
    • Extension cap enforcement (count < max)
    • Proposed end time calculation
    • Monotonic check (proposed_end > end_time)
    • Update end_time when extending
    • Increment extensions_count

Safety & Quality

  • Overflow-safe arithmetic

    • checked_sub() for threshold calculation
    • checked_add() for proposed end time
    • checked_add() for counter increment

  • Disable mechanism

    • Check extension_window > 0
    • Check extension_amount > 0
    • Skip logic if either is 0

  • Error handling

    • Proper panic messages for overflow
    • Graceful handling of edge cases

✅ Test Coverage

Updated Existing Tests (16 tests)

  • bid_refunded_event_emitted_on_outbid
  • equal_to_highest_bid_rejected_as_bid_too_low
  • fuzz_bid_sequence_invariants_deterministic
  • fuzz_refund_balance_invariant_deterministic
  • close_semantics_cannot_be_bypassed
  • settle_default_liquidation_requires_closed_auction
  • settle_default_liquidation_emits_once_after_close
  • zero_bid_auction_settles_with_borrower_as_winner
  • bid_after_end_time_rejected
  • close_auction_emits_event
  • init_auction_rejects_increment_bps_above_10000

New Anti-Snipe Tests (7 tests)

  • anti_snipe_pre_window_bid_no_extension

    • Bid before threshold
    • Assert end_time unchanged
    • Assert extensions_count = 0

  • anti_snipe_late_bid_triggers_extension

    • Bid within window
    • Assert end_time extended correctly
    • Assert extensions_count incremented

  • anti_snipe_extension_cap_enforced

    • Multiple consecutive late bids
    • Assert first N extend (N = max_extensions)
    • Assert remaining bids don't extend
    • Assert extensions_count caps at max

  • anti_snipe_disabled_when_extension_window_zero

    • Set extension_window = 0
    • Late bid placed
    • Assert no extension occurs

  • anti_snipe_disabled_when_extension_amount_zero

    • Set extension_amount = 0
    • Late bid placed
    • Assert no extension occurs

  • anti_snipe_bid_at_exact_threshold

    • Bid at exact threshold time
    • Assert extension triggered

  • anti_snipe_no_extension_if_proposed_end_not_greater

    • Bid where proposed_end <= end_time
    • Assert no extension occurs

Test Quality Standards

  • All tests use explicit fn declarations (no closures)
  • Time manipulation uses env.ledger().with_mut(|li| { li.timestamp = target; })
  • All assertions verify exact state values
  • All tests have descriptive names
  • All tests have clear documentation comments
