Detailed Description

Injected non-volatile store for the calibration record.

A store with a NULL read is legal and simply means "no per-device record on this build" – the resolver skips that source rather than failing, so a board without data flash still resolves from the controller or from provisioning.

Invariant

read and write are either NULL or callable for the lifetime of every resolve / provision call.

Example:

const ra8_epd_cal_store_t store = {.read = my_read, .write = my_write,
                                   .ctx = nullptr};
