  "_comment": "SPEC.md §27 Human Accountability fixtures. Top-level OBJECT (no execution_hash, not an array) so schema-validate.mjs SKIPS it — only validate-ha-records.test.mjs consumes it. It exercises the four §27 behavioral invariants: additivity (§27.0), threshold distinctness (§27.3), override expiry (§27.5), and the signed-named-human requirement (§27.2).",
