I always saw byte as something that was relevant for systems that could address
objects smaller than words... “byte addressed” machines. The term was mnemonic
for something bigger than a bit and smaller than a word. It was usually 8 bits
=but there were 36-bit machines that were byte

The terms "octet" and "decade" were prevalent across Europe in the 1970s.
Certainly we used them both when I was first learning about computers. My

Where I wrote "ASCII" I should have written "text".

You mean that size of a word. The word "byte" means "by eight". It did

I had this misconception at some point too. Double quotes
Double quotes is specifically for building identifiers that "look strange"
(i.e. embedded spaces, keywords, ...) which IMHO should be avoided because it
tends to clutter up the statement.
Single quotes is for building strings.

This is an orthogonal problem: if the sender is sending you data that is
not what it should be, then he could just as well be sending you
well-encoded and well-formed but invalid data, or malware, or
confidential/personal data

Autoincrementing is an SQLite variant.
Default values are standard SQL.
It should be noted that standard SQL (above Entry SQL level) allows
DEFAULT in row value constructors.

Ha, that's a very good idea. I didn't have triggers in the radar.
