// 1. Create an Account
let acc1_id = 101;
let user1_id = 1;
let acc1 = new_account(acc1_id, "User1 Main Account", user1_id, "Primary account for User 1", "LedgerX", "0x123MainSt", "pubkeyUser1");
print(`Created account: ${acc1.name} with ID ${acc1.id}`);

// 2. Save Account to Mock DB
set_account(acc1);
print(`Account ${acc1.id} saved to DB.`);

// 3. Retrieve Account from Mock DB
let fetched_acc1 = get_account_by_id(acc1_id);
print(`Fetched account from DB: ${fetched_acc1.name}, User ID: ${fetched_acc1.user_id}`);

// 4. Create an Asset
let asset1_id = 201;
let asset1 = new_asset(asset1_id, "HeroCoin", "Utility token for Hero Platform", 1000.0, "0xTokenContract", "Erc20", 18);
print(`Created asset: ${asset1.name} (ID: ${asset1.id}), Amount: ${asset1.amount}, Type: ${asset1.asset_type_str}`);

// 6. Retrieve Asset from Mock DB
let fetched_asset1 = get_asset_by_id(asset1_id);
print(`Fetched asset from DB: ${fetched_asset1.name}, Address: ${fetched_asset1.address}`);

// 7. Add Asset to Account (using the fetched instances)
// Note: Account::add_asset takes Asset by value. We have 'fetched_asset1'.
// The 'add_asset' method on the Account object in Rhai should work with the asset object.
// First, let's ensure fetched_acc1 is mutable if 'add_asset' modifies it directly.
// Or, if add_asset returns a new Account, we'd do: fetched_acc1 = fetched_acc1.add_asset(fetched_asset1);
// For now, assuming add_asset modifies in place (Rust methods taking `&mut self` often allow this if the object itself is mutable in Rhai scope)
// If Account.add_asset was registered as `fn(&mut Account, Asset)` then: 
// fetched_acc1.add_asset(fetched_asset1);
// Let's assume for now that `add_asset` is available and works. We'll test this.
// For the current setup, `Account::add_asset` takes `&mut self`, so the object must be mutable in Rhai.
// We might need to re-fetch or re-set the account if we modify it and want the DB to know.
// Let's try to add and then re-save the account.

// For simplicity in this first script, let's focus on marketplace.
// Adding asset to account might require more setup in Rhai regarding object mutability
// or how the add_asset method is exposed. We can refine this later.
print("Skipping adding asset to account directly in this script version for brevity, focusing on listing.");

// Add bid to listing - this requires the listing object to be mutable
// and the add_listing_bid function to be correctly registered to modify it.
// For now, we'll assume the function works and we'd need to re-set the listing to DB if modified.
// To test `add_listing_bid` properly, we would typically do:
// let mut mutable_auction_listing = get_listing_by_id(listing2_id);
// mutable_auction_listing.add_listing_bid(bid1);
// set_listing(mutable_auction_listing);
// print(`Bid added to listing ${mutable_auction_listing.id}. New bid count: ${mutable_auction_listing.bids_cloned.len()}`);
