/**
 * Role-scoped, advisory operation readiness + planning-confidence aggregates.
 *
 * One row per (subjectType, subjectId, windowStart). Writes are internal only
 * (create/update/delete denied; the readiness service writes via `overrideAccess`
 * with its own permission gate). Read is gated by the NEW
 * `operation-readiness:read` permission, so it is role-scoped, not open to any
 * logged-in user.
 *
 * The stored row carries only normalized scores, category weights, and input
 * counts plus a generated explanation. It never contains raw evaluation content
 * (evaluator names, rater ids, or comment text), which is what the privacy
 * guarantee rests on.
