/**
 * design/252 review r3 — read a foreign {@link OrgGateVerdict} the way the personal-rule answer is read:
 * OWN DATA properties only, never the prototype chain, never an accessor.
 *
 * Unlike the personal-rule normalizer below, this one accepts ANY non-array object as the carrier —
 * not only a plain record. The two seams tighten in opposite directions when a shape is refused: the
 * personal lane is a LOOSENING seam, so refusing a class instance degrades toward asking; this answer
 * carries the org's DENY, and folding a structurally valid `{status:"available", verdict:{behavior:
 * "deny"}}` class instance into `unavailable` would LOOSEN it — from a deny nobody can approve into a
 * real-approval ask a person can clear. A class instance's fields are its own data properties, so the
 * own-data read below already gives the full pollution guarantee (inherited members never authorize);
 * the prototype test added nothing here but the downgrade.
 *
 * The two seams are the same class of trust boundary and were not being read the same way. What that
 * cost here is worse than on the personal lane, because this answer is GOVERNANCE:
 *  · an inherited `revision` (a polluted `Object.prototype`) stamped a fabricated snapshot version onto
 *    a human's approval request — a WRONG record, which is worse than an absent one;
 *  · an inherited `verdict` invented an org rule, and with it an org ask or deny the lane never gave;
 *  · an answer that is not a record at all read as "available, nothing to say", i.e. the governance
 *    fail-open the availability contract exists to prevent.
 * Anything this function cannot read as a well-formed answer becomes `unavailable` — the fail-CLOSED
 * word, never the empty one.

 * outside every accepted shape — a number, `null`, an object with neither `rules` nor `unreadable`, an
 * EMPTY `rules` array, the retired pre-375 `{ rule, dots? }` single-rule object — is read as a clean
 * negative rather than a match: this is a LOOSENING seam, so an answer nobody can name degrades toward
 * asking, never toward an allow built on it. All-or-nothing across the set's TEXTS for the same
 * reason: a set with one unreadable member is a different (smaller) claim than the lane made, and a
 * decision must not stand on a claim nobody made — one bad member drops the whole answer to the clean
 * negative. Per-member DOTS stay individually optional (identity lost ⇒ `"not_reported"`, exactly the
 * single-rule contract).
 *
 * The hit's dots are COPIED, not aliased. The array travels onto an ask that may sit in front of a
 * person for a long time; a lane that retains and mutates its own array would otherwise change what the
 * approver is looking at, and what an audit later reads, after the evidence was stamped.
