Data Fields
ra8_rot_antirollback_read_fn_t	read
	Read stored highest-accepted version.
ra8_rot_antirollback_commit_fn_t	commit
	Persist the newly-accepted version.

Detailed Description

Dependency-injection vtable for the non-volatile version counter.

The single seam between the pure anti-rollback policy and the durable storage that backs the monotonic counter. Production wires the real OTP / data-flash accessors; host tests wire mocks. Both function pointers must be non-NULL for ra8_rot_antirollback_verify to proceed – a NULL member is a default-deny.

Invariant

read and commit are either both wired to a real backing or both report "not provisioned" (never one of each).

Example:

const ra8_rot_antirollback_store_t* store = ra8_rot_antirollback_default_store();
ra8_err_t err = ra8_rot_antirollback_verify(store, image_version);
