Reproduction only

This PR adds reproduction tests only. No implementation fix is included. CI is expected to fail until the underlying issue is fixed.

Covered audit issues

1. core-g-r-layermap-preload-options-ignored: LayerMap preload options have no runtime effect

Module: LayerMap

Expected contract: Supplying preloadKeys, or preload: true through fromRecord or Service, builds the selected entries while constructing the map and exposes layer failures through the conditional construction error type.

Observed result: The intended failure was reproduced: acquired keys were [] instead of ["a", "b"].

Reproduction command:

pnpm vitest run packages/effect/test/LayerMap.test.ts -t "make preloads the requested keys"

  • Reproduction test for LayerMap.make preloadKeys — adds a focused it.effect test in LayerMap.test.ts that creates a map with preloadKeys: ["a", "b"] and asserts the corresponding layers were built during construction. The test correctly fails because the make implementation ignores the preloadKeys option at runtime.

  • Fixed LayerMap.make ignoring preloadKeys — added the missing runtime options field and a preloading loop that calls RcMap.get for each key during construction, matching the type-level signature that already propagated the error channel.
  • Unblocked fromRecord preload path — the existing preload: true → preloadKeys: Object.keys(layers) computation in fromRecord was silently ignored at runtime; now works correctly.
  • Added changeset — patch-level fix for the effect package.

  • Applied Effect.scoped to preload RcMap.get — wrapped each RcMap.get(rcMap, key) call in Effect.scoped(...) per @tim-smart's suggestion to ensure preloaded entries are properly scoped.
