/**
 * # cli/backend/catalog-records — the LOADER for the baked catalog-conformant contract fixture (kestrel-djm.5, kestrel-nvxb)
 *
 * The pre-computed, content-addressed protocol artifacts the catalog-conformant contract server
 * ({@link ./mock.ts}) serves so the SDK's HTTP transport returns the SAME protocol Blotter / transcript /
 * grade / root the LOCAL projection yields (the djm.5 headline reconciliation).
 *
 * kestrel-nvxb (arch-review A8): the ~7,200-line generated `CATALOG_RECORDS` literal that used to live INLINE
 * in this source file — 99% of the largest file in the tree — is now a BUILD ARTIFACT at
 * {@link ../../../artifacts/sdk/catalog-records.json}, generated by scripts/sdk/bake-catalog-records.ts. This
 * module is a thin, hand-written, STABLE loader: it statically imports that JSON data artifact (a pure-data
 * value edge — no engine, no code) and re-exports it under the djm.2 protocol types. Moving the literal out
 * of `src/` does NOT change the served bytes: `mock.ts`'s `json()` stringifies the SAME in-memory objects in
 * the SAME key order (JSON.parse preserves the artifact's key order), so `GET /catalog` and the served
 * records are byte-identical to the old inline form.
 *
 * Guards on this fixture:
 *  - tests/sdk.transports.test.ts            — HTTP↔LOCAL protocol digest parity (the drift guard).
 *  - tests/sdk.transport-fixture-freshness.test.ts — every baked record byte-equals a fresh LOCAL engine run.
 *  - tests/cli.mock-catalog-bytes.test.ts    — the REAL mock server serves byte-identical records through the
 *                                              loader+artifact seam (the kestrel-nvxb served-byte parity guard).
 * Regenerate on any engine / catalog-root change:
 *   bun scripts/sdk/bake-catalog-records.ts
 *
 * LIGHT: the loader imports ONLY the pure-data JSON artifact + type-only protocol imports (erased) — the
 * server stays on the light remote graph (tests/package.boundary.test.ts).
