Override via RIG_TEMPLATES_REF when the drill was pointed somewhere; else
the pin read from the INSTALLED candidate tree — what actually landed,
never this checkout's copy.
test/drill.sh awk-extracts the harness's decision functions (the
release.sh pattern) and drives them against fixtures: the ref refusal
names both refs, a loud skip never classifies as a pass, the idempotence
verdict is a real diff that goes non-empty when convergence is broken —
demonstrated mechanically on every CI run — and the record emitter
cannot produce a clean-sweep reading over a skipped leg. CI runs it in
the check job.
The tests caught three real harness bugs before any reviewer could:
printf eating a '- '-leading format as options (a silently empty Failed
section — the exact lie the record exists to prevent), tree_of trusting
GNU readlink -f's exit 0 on a dangling final component, and the arg
refusals sitting behind the root check in violation of the repo's own
validated-before-root doctrine.
