/**
 * The composition contract: the full set of store ports, plus the clock seam.
 *
 * Every method on every port in this package obeys two rules, and
 * `src/__tests__/constraints.test.ts` enumerates them method by method to prove
 * it (sprint I7):
 *
 * 1. **Async.** Every method returns a `Promise`. A synchronous port would
 *    silently exclude SQL and object-store compositions from the contract.
 * 2. **Tenant-first.** Every method's first parameter is a required
 *    {@link TenantId}. There is no bare `deviceId`/`taskId` lookup anywhere —
 *    §12.6.2 layer 3 forbids the index such a lookup would need, and layer 5
 *    requires the tenant to be part of the lookup key rather than a second
 *    comparison step that can be forgotten.
 *
 * No port method can change the tenant of an existing row. That is not an
 * omission: "move this to another tenant" is the one operation that would make
 * every cross-tenant assertion in the conformance suite unfalsifiable.
