Feature: If an automated purchase order is only partially filled on auction uncrossing, the order is removed from the book automatically (as it is a GFA order), any swapped tokens transferred to the correct to account, and the remaining earmarked funds returned to the relevant source account. (0097-PAPU-045).

            | ETH | 0              |

        And the spot markets:

        Given the parties deposit on asset's general account the following amount:
            | party  | asset | amount     |
            | party1 | ETH   | 1000000000 |

            | lpprov | BTC/ETH   | 2         | 1                    | buy  | MID              | 50     | 100    |

        When the opening auction period ends for market "BTC/ETH"

        And the following trades should be executed:
            | buyer  | price   | size | seller |
            | party1 | 1000000 | 1    | party3 |
        And the mark price should be "1000000" for the market "BTC/ETH"

        And the composite price oracles from "0xCAFECAFE2":
            | name         | price property   | price type   | price decimals |
            | price_oracle | prices.ETH.value | TYPE_INTEGER | 0              |

        And the time triggers oracle spec is:

            | auction_schedule          | 1727136001 | 30    |
            | auction_vol_snap_schedule | 1727136000 | 30    |

        And the average block duration is "1"

        And the parties deposit on asset's general account the following amount:
            | party                                                            | asset | amount |

        Given time is updated to "2024-09-24T00:00:00Z"
        And the parties submit the following one off transfers:
            | id | from                                                             | from_account_type    | to                                                               | to_account_type            | asset | amount | delivery_time        |

    Scenario: PAP is setup for the market, an amout is earmark and an order is submitted to a pap auction, however the order is only partially filled and the remaining amount is uneamarked and returned. (0097-PAPU-045)
        When the protocol automated purchase is defined as:
            | id    | from | from account type          | to account type               | market id | price oracle | price oracle staleness tolerance | oracle offset factor | auction schedule oracle | auction volume snapshot schedule oracle | auction duration | minimum auction size | maximum auction size | expiry timestamp |
            | 12345 | BTC  | ACCOUNT_TYPE_BUY_BACK_FEES | ACCOUNT_TYPE_NETWORK_TREASURY | BTC/ETH   | price_oracle | 10s                              | 1.01                 | auction_schedule        | auction_vol_snap_schedule               | 60s              | 100                  | 200                  | 0                |

        Then the oracles broadcast data with block time signed with "0xCAFECAFE2":
            | name             | value   | time offset |
            | prices.ETH.value | 1000000 | -1s         |

        And the network moves ahead "30" blocks

        # maximum auction size is 200 so expect 200 to be earmarked
        Then the automated purchase program for market "BTC/ETH" should have a snapshot balance of "200"

        # we enter a pap auction
        And the trading mode should be "TRADING_MODE_PROTOCOL_AUTOMATED_PURCHASE_AUCTION" for the market "BTC/ETH"

        # an order for sell BTC with size 200 and price 1.01 * 1000000 is placed
        And the order book should have the following volumes for market "BTC/ETH":
            | side | price   | volume |
            | sell | 1010000 | 200    |

        # lets place a limit order for the buy at 101000 so it crosses for half of the amount
        And the parties place the following orders:
            | party  | market id | side | volume | price   | resulting trades | type       | tif     | reference |
            | party2 | BTC/ETH   | buy  | 100    | 1010000 | 0                | TYPE_LIMIT | TIF_GTC | t2-b-1    |

        # move to the end of the auction
        And the network moves ahead "61" blocks

        # expect to leave the auction
        And the trading mode should be "TRADING_MODE_CONTINUOUS" for the market "BTC/ETH"

        # exepct 100 BTC to have moved from the bb fees account on BTC
        And the buy back fees balance should be "4900" for the asset "BTC"
        # infra fee = 1e-3
        # liq fee = 1e-1
        # total fees for network = 0.101/2 = 0.0505 * 1010000 * 100 = 5,100,500
        # the network treasury on ETH should get 1010000 * 100 -  5100500 = 95,899,500
        And the network treasury balance should be "95899500" for the asset "ETH"
        And "party2" should have general account balance of "100" for asset "BTC"
