Very unobservant of me. Thanks.

I've tried the following code, copied from the boot.h documentation.
However, no write. This leads me to suspect that I'm somehow running
into some memory protection issue, which is where I'll look next. So:
per ardua ad astra!
command result_t ProgFlash.write(in_flash_addr_t addr, uint8_t* buf,
in_flash_addr_t len) {
uint16_t* wordBuf = (uint16_t*)buf;
uint32_t i;
if ( addr + len > TOSBOOT_START )
return FAIL;
eeprom_busy_wait();
boot_page_erase( addr );
boot_spm_busy_wait();
for ( i = 0; i < len; i += 2 )
boot_page_fill( addr + i, *wordBuf++ );
boot_page_write( addr );
boot_spm_busy_wait();
boot_rww_enable();
return SUCCESS;
}
