/**
 * INPUT_CONTRACTS — SSoT registry of per-operation input contracts.
 *
 * Keyed by the canonical `<domain>.<verb>` operation identifier (e.g.
 * `'tasks.add'`, `'tasks.add-batch'`, `'tasks.update'`). The value type uses
 * `OperationInputContract<unknown>` so the map is assignable across
 * operations with different input shapes — callers that need the concrete
 * `T` must narrow via an operation-specific accessor.
 *
 * Originally seeded by T9918 (PR #663) with a single `tasks.add-batch`
 * entry to back the `cleo schema <op> --input/--examples` introspection
 * surface. T9917 extends the registry to cover the full tasks.* mutate
 * surface (add + add-batch + update) and rewires the schemas to live in
 * `packages/contracts/src/operations/tasks.ts` so the CLI commands
 * import them via the contracts leaf package (no Core dependency hop).
 *
 * CLI commands look up their contract by operation name, hand the raw
 * payload to `validateOperationInput()` (T9915), then forward the
 * narrowed value through `dispatchRaw`. Every retrofit (T9917+) extends
 * this map.
 *
 * @packageDocumentation
 * @module @cleocode/core/dispatch/contracts/input-contracts
 *
 * @epic T9855
 * @task T9918 — original seed entry + getInputContract accessor
 * @task T9917 — tasks.add + tasks.update extension; schemas moved to contracts
