/**
 * Harness template for the `cachedProjection` assembly arm.
 *
 * Disposition is resolved at COMPILE TIME by `scripts/capsule-compile.ts` (the
 * same probe pattern `pureTransform` and `stateMachine` use), so the generated
 * file is ALWAYS one clean, real test with no defensive runtime `throw`-if-missing
 * branches:
 *
 *  - **real-only fixture form** ({@link HarnessContext.cachedProjectionRealOnly}
 *    + a {@link HarnessContext.fixturePath}) — the source schema is a
 *    Declaration-tagged `instanceOf(ArrayBuffer)` that is deliberately not
 *    arbitrary-derivable, so the canonical fixture bytes are the source of
 *    truth. Emits fixture-driven `cache-hit` / invalidation / determinism /
 *    invariant probes over the REAL `derive`, plus a REAL decode-throughput bench.
 *  - **real property form** ({@link HarnessContext.arbitraryDerivable}) — the
 *    source schema IS arbitrary-derivable, so the harness samples it via the
 *    canonical `schemaToArbitrary` walker and drives `derive` over random
 *    sources for the determinism + invariant properties.
 *  - **FAIL the compile loud** — any lesser disposition (no binding, no
 *    derive/fixture, a non-derivable source with no fixture) THROWS a tagged
 *    `UnsupportedError` so `capsule:compile` fails loud (wire-or-fail). The
 *    generated file is never an `it.skip`, never a `() => true` placeholder, and
 *    never carries a runtime `try/catch schemaToArbitrary ... else throw` branch
 *    that decides derivability at test time.
