Currently quite hard/impossible to get this right without a lot of insider knowledge.

• [ ] missing docs about which pin to pick for log
• [x] productId is false, documentation points to wrong documentation page on jacdac-docs
• [ ] schema could use help pointing back to original process
• [ ] unclear how to test that the mapping is correct

crypto is not properly wired up in jacdac-ts/node and it generates "undefined" instead of random bytes.
