Detailed Description

Dependency-injection vtable for the record backing store.

The single seam between the hardware-agnostic record logic and the durable medium (NASA Power-of-10 Rule 9 deviation: function pointers enable Dependency Inversion and host mock injection). Production binds ra8_devcfg_default_store (extra-MRAM); host tests bind a RAM mock. Both members must be non-NULL for ra8_devcfg_load / ra8_devcfg_commit to proceed. This mirrors the ra8_epd_cal_store_t and ra8_rot_antirollback_store_t seams; callers reach the backing only through this vtable, never by naming a backend symbol.

Invariant

read and write are either both bound to a real backing or both bound to a mock (never one of each).

Example:

const ra8_devcfg_store_t* store = ra8_devcfg_default_store();
if (ra8_devcfg_load(store) == k_ra8_ok) {
  uint16_t mv = 0U;
  if (ra8_devcfg_get_vcom_mv(&mv) == k_ra8_ok) { drive_panel(mv); }
}
