Trade statuses

Two independent axes: legacy numeric status and escrow_status / is_released / release_date.

Trade status is two independent axes. Frontend copy and API numeric names differ slightly; the numbers below are the contract.

A) Legacy numeric status

Still returned on the wire. Documented as current values, with the old meaning of 0 called out.

status	API name	Frontend copy	Meaning	State
`0`	Processing	Processing trade	Funds frozen, trade session created. OLD docs said “waiting for user to buy more items” — that meaning is DEPRECATED.	current
`1`	Creating	Creating exchange	Pushing the Steam offer. Also treat 2/4 without trade_id as creating.	current
`2`	Seller confirm	Confirm trade / Waiting for seller	Waiting for seller Steam Guard.	current
`3`	unused Deprecated	—	Do not emit, do not document as valid.	deprecated/unused
`4`	Buyer accept	Accept / Waiting for buyer	Trade sent, buyer can accept. If release_date is set and is_released=false → TRADE HOLD (new).	current + hold overlay
`5`	Completed	Confirmed	Item delivered.	current
`6`	Declined/refunded	Cancelled / Unconfirmed	Failed; see reason.	current

sending
is_released + release_date = Steam trade-hold after accept (status 4).
penalties on buyer-fault rollbacks: rollback_fee (20%), rollback_penalty (10%), total_penalty.

0 Processing→1 Creating→2 Seller confirm→4 Buyer accept→5 Completed

From 4, if release_date is set and is_released=false, overlay hold until release, then 5. Any failure → 6 Declined. Status 3 is unused.
