/**
 * Schema factories for sharing/ownership.
 *
 * Templates make a resource table "ownable" by spreading `ownableColumns()` into
 * the table definition and declaring a companion shares table via
 * `createSharesTable()`. The shares table carries per-principal grants; the
 * parent table's `visibility` column is the coarse default (private / org /
 * public).
 *
 *   import { table, text, ownableColumns, createSharesTable } from
 *     "@agent-native/core/db/schema";
 *
 *   export const decks = table("decks", {
 *     id: text("id").primaryKey(),
 *     title: text("title").notNull(),
 *     data: text("data").notNull(),
 *     ...ownableColumns(),
 *   });
 *
 *   export const deckShares = createSharesTable("deck_shares");
 *
 * The share row `role` supports `viewer | editor | admin`. `admin` is a
 * share-level capability — it lets non-owners manage shares. The single
 * `owner_email` column on the resource remains the ground truth for ownership.
 */
/**
 * Columns any ownable resource should include. Spread into the table definition.
 *
 * - `ownerEmail` — the creator. Auto-filled by write actions from the request context.
 * - `orgId`     — owner's active org at creation time. Used for `visibility = 'org'` checks.
 * - `visibility`— coarse default: `'private' | 'org' | 'public'`. Default `'private'`.

 * - `resourceId`      — id of the parent resource
 * - `principalType`   — `'user' | 'org'`

 * at the action layer via upsert-style logic. A composite DB-level unique
