Poor man's bitemporal data system in SQLite and Clojure

On trying to mash up SQLite with ideas stolen from Accountants, Clojure, Datomic, XTDB, Rama, and Local-first-ers, to satisfy Henderson's Tenth Law. Viz., to make a sufficiently complicated data system containing an ad-hoc, informally-specified, bug-ridden, slow implementation of half of a bitemporal database. Because? Because laying about on a hammock, contemplating hopelessly complected objects like Current Databases isn't just for the Rich man.

Keeping it Old-Tool: REPL habits of a grug-brained Clojure programmer

Is demo of Grug Clojure code vibe. He no catch onto cloud LLM magics for some reason. Still prefer program with only brain-muscles. Prefer use Grug language standard library and standard dev tools. Prefer make and use all byte on local disk. Maybe luddite, maybe obsolete. Grug no mind. Fine with how he code. Besides, Grug like muscles. Hope maybe you see tip, trick, tactic to steal. Take what can use, no take what no can use.
