Ghost items in inventory

[NikittyS]

Hi. I have fresh account with cs2 prime, there is 4 items in inventory - two empty storage units, one skin and one crate.
If I get a list of items through this module, there are more items than I see in the game inventory. Besides my items, there are four more.

This two items with strange IDs
[{"attribute":[],"equipped_state":[],"id":"17293822569102708641","account_id":1730000000,"inventory":3221225477,"def_index":4001,"quantity":1,"level":1,"quality":4,"flags":24,"origin":8,"custom_name":null,"custom_desc":null,"interior_item":null,"in_use":false,"style":null,"original_id":null,"rarity":1,"position":0},{"attribute":[{"def_index":6,"value":null,"value_bytes":{"type":"Buffer","data":[0,0,250,66]}}],"equipped_state":[],"id":"17293822569110896676","account_id":1730000000,"inventory":3221225477,"def_index":36,"quantity":1,"level":1,"quality":1,"flags":24,"origin":8,"custom_name":null,"custom_desc":null,"interior_item":null,"in_use":false,"style":null,"original_id":null,"rarity":4,"position":0,"paint_index":125}]

And these two look like graffiti
[{"attribute":[{"def_index":277,"value":null,"value_bytes":{"type":"Buffer","data":[1,0,0,0]}},{"def_index":113,"value":null,"value_bytes":{"type":"Buffer","data":[197,6,0,0]}},{"def_index":233,"value":null,"value_bytes":{"type":"Buffer","data":[19,0,0,0]}}],"equipped_state":[],"id":"37944853743","account_id":1730000000,"inventory":1,"def_index":1348,"quantity":1,"level":1,"quality":4,"flags":0,"origin":24,"custom_name":null,"custom_desc":null,"interior_item":null,"in_use":false,"style":null,"original_id":null,"rarity":1,"position":1,"stickers":[{"slot":0,"sticker_id":1733,"wear":null,"scale":null,"rotation":null,"offset_x":null,"offset_y":null}]},{"attribute":[{"def_index":277,"value":null,"value_bytes":{"type":"Buffer","data":[1,0,0,0]}},{"def_index":113,"value":null,"value_bytes":{"type":"Buffer","data":[185,6,0,0]}},{"def_index":233,"value":null,"value_bytes":{"type":"Buffer","data":[14,0,0,0]}}],"equipped_state":[],"id":"37944853744","account_id":1730000000,"inventory":1,"def_index":1348,"quantity":1,"level":1,"quality":4,"flags":0,"origin":24,"custom_name":null,"custom_desc":null,"interior_item":null,"in_use":false,"style":null,"original_id":null,"rarity":1,"position":1,"stickers":[{"slot":0,"sticker_id":1721,"wear":null,"scale":null,"rotation":null,"offset_x":null,"offset_y":null}]}]

But I don't have any graffiti, and I haven't had any in the past. May be you can explain what is that?

I don't know a ton about CS2, but in TF2 things like contracts (I believe the CS equivalent is operations?) are communicated to the client as CSOEconItem objects with a specific flag (NotEcon) set to indicate that they aren't actually econ items. What you're seeing is likely something like that.

Both of your mystery items have a flags value of 24. That includes 8 (24 = 8 + 16), which is NotEcon.

Thanks for your answer about the first two items. I figured out what about the second two (graffiti). It's a weekly reward where the game offers to choose 2 items out of 4. Items that aren't chosen have an attribute with definex 277 and are simply hidden from the inventory. Maybe this information will help someone.

"277"
{
"name" "free reward status"
"attribute_class" "free_reward_status"
"description_format" "value_is_additive"
"hidden" "1"
"effect_type" "neutral"
"stored_as_integer" "1"
}
