Method	Purpose
`__init__(path, max_capacity=50)`	Bind path, set FIFO cap.
`append(item_type, data)`	Enqueue. Tail-evict on overflow.
`pop_all() / drain()`	Atomically read + clear (used by dream).
`push_front(items)`	Re-queue items at head if dream couldn't process them; preserves order, drops new appends if needed.
`load()`	Read current journal without clearing.
