/**
 * Leadership evaluations.
 *
 * One row per (rater, ratee, mission, kind) — the uniqueness is enforced by the
 * service layer (`upsertEvaluation` in `src/lib/evaluations`), not by a DB
 * constraint.
 *
 * Privacy model: raw documents are only readable/writable by users holding the
 * `evaluations:*` permissions (admin/developer via role docs). Normal users never
 * receive raw rows over REST — the profile UI consumes pre-aggregated, rater-free
 * output produced by server actions that call the service with explicit RBAC gating.
 * `rater` and `comment` are private fields and must never be surfaced to normal
 * users by any read path.
