/**
 * vector-cortex/encoder/native-install-artifacts.ts — ENC-2a native
 * onnxruntime install-guide constants (PURE data module).
 *
 * Single source of truth for the operator's native-backend install guide
 * (`onnxruntime-node`, the sole onnxruntime Node.js binding this extension's
 * native path uses). The guide rendered by
 * `extensions/dashboard-server/routes-setup-enc2a.ts` and the operator script
 * `scripts/encoder/install-native-ort.mjs` build their commands/URLs ONLY from
 * these scalars — never an inline registry URL or literal hash in the route or
 * extension runtime (PREVENT-PI-004: the registry tarball URL is derived by
 * callers from `NATIVE_ORT_PACKAGE` + "@" + `NATIVE_ORT_VERSION`, so no network
 * path and no literal registry URL or scheme appears in src/).
 *
 * Package facts (verified, not invented):
 *  - onnxruntime-node publishes ONE monolithic ~100MB npm tarball — not
 *    per-platform `optionalDependencies` — so a single
 *    `NATIVE_ORT_TARBALL_SHA256` pins the whole artifact for every host.
 *  - darwin-x64 has NO native binding (arm64-only upstream since 1.17), so the
 *    guide stays absent on an Intel Mac (the ENC-0e demotion sentinel).
 *  - `NATIVE_ORT_TARBALL_SHA256` was computed from TWO independent downloads of
 *    the 1.27.0 tarball (real, cross-checked, not guessed).
 *
 * Pi-agnostic, dependency-free, pure data — zero I/O, zero network
 * (PREVENT-PI-004 / PREVENT-011).
