drill/README.md is the repeatable procedure #107's second checkbox asks
for: prerequisites (the throwaway machine, the tagged key, the fork's
drill workflow, the pins), the invocation, what each leg asserts, where
the record lands. drills/README.md's harness disclaimer flips to point
at the instrument, its legs list and example record match what
drill.sh actually runs and emits, and CONTRIBUTING's drill sentence
names the script. Changelog entry under Unreleased.
