The notify_state_deferred_ lambda captured [this, state, progress, error] (16 bytes on 32-bit), exceeding std::function SBO and forcing a heap allocation on every OTA progress update. Pack the three values into a single uint32_t: - state (8 bits) + error (8 bits) + progress as fixed-point (16 bits) The lambda now captures [this, packed] (8 bytes), fitting in SBO. Progress resolution of 0.01% is more than adequate for OTA reporting.
