Detailed Description

Injected dependencies + caller-owned buffers for cache_store_demo_run.

Open/Closed seam: the demo owns no globals. The LevelX control block, the physical-flash driver bind, the store index array, the one-sector staging buffer, and a read-back scratch buffer are all passed in, so the ARM app (RAM driver over SRAM) and the host test (RAM driver on the host) drive the same core through different buffers.

Invariant

nor_flash, nor_driver_init, index, staging, and scratch are non-NULL; index_cap > 0; scratch_bytes covers the largest demo blob.
