### What? Add focused production adapter coverage for configured `cacheHandler` and `cacheHandlers` module graphs in Node `output.assets`, including transitive helper dependencies and Turbopack `assetsHashes` assertions. ### Why? Adapter deployments dynamically load configured cache handlers at runtime. This coverage demonstrates that Node adapter outputs currently omit those handler files and their transitive dependencies. ### How? Add an App Router Cache Components fixture using `adapterPath`, both cache-handler APIs, and a `use cache: remote` route. Its adapter writes `onBuildComplete` context to disk and the test inspects Node outputs for each handler and uniquely named helper. ### Verification - `NEXT_TEST_PREFER_OFFLINE=1 pnpm --filter=next build` - Expected failure: `NEXT_TEST_PREFER_OFFLINE=1 pnpm test-start-turbo test/production/app-dir/adapter-cache-handlers/adapter-cache-handlers.test.ts` (no Node output contains all four handler assets) - Expected failure: `NEXT_TEST_PREFER_OFFLINE=1 pnpm test-start-webpack test/production/app-dir/adapter-cache-handlers/adapter-cache-handlers.test.ts` (same adapter handoff gap) - `git diff canary --check` - Not run continuously: `pnpm --filter=next dev` (`EMFILE: too many open files` occurred after startup in the local watcher) <!-- NEXT_JS_LLM_PR --> --------- Co-authored-by: Niklas Mischkulnig <[email protected]>
