Answers zone-engine ZONE-WP-0001-T01.
Decision 5.6 — enforcement stance is a sibling standard, not an axis. The six
ladders are monotone and the whole current/target/guard machinery depends on it;
enforcement stance is not (ADR-0006 is the finding that the top rung is wrong for
the SSH lane). And this framework is descriptive: an accurately declared exempt
would be conformant and exempt. Membership is declared, stance belongs to the
control owner. Zone membership rides tenancy.yaml under a reserved zones: key so
the estate keeps one declaration surface; the schema permits it, unconstrained.
Decisions 8.4.1/8.4.2 — 'substrate location is not evidence' stated once instead
of three repo-local slogans, and the reef/P/V gap recorded as this document's
defect rather than zone-engine's scope. NK-WP-0027 takes it.
