Written for two readers: me in a year having forgotten all of it, and
anyone who stumbles on the repo and finds the idea worth stealing.
Leads with why the design gives things up rather than what it does, since
the giving up is the interesting part. Records the operational facts that
live nowhere in the code, points at FINDINGS.md for the things worth not
rediscovering, and ends with the changes this system should refuse.
Also marks validate.py and test_prune.py executable, since the README
invokes them directly.
