+Validate `devEngines.runtime` and `engines.runtime` version ranges for `node`, `deno`, and `bun` when `onFail` is set to `error` or `warn`. Previously these settings only had an effect with `onFail: 'download'` — the `error` and `warn` modes silently did nothing [#11818](https://github.com/pnpm/pnpm/issues/11818). Violations now throw `ERR_PNPM_BAD_RUNTIME_VERSION`.

-
-- 3ddde2b: **fix**: anchor the side-effects-cache key and global-virtual-store hash to the project's script-runner Node — `engines.runtime` pin when present, shell `node` otherwise — instead of pnpm's own runtime.
-
-  `ENGINE_NAME` (the `<platform>;<arch>;node<major>` prefix used as the side-effects-cache key and the engine portion of the GVS hash) was computed from `process.version` — the Node that runs pnpm itself. That was wrong in two situations:
-
-  1. **`@pnpm/exe` SEA bundle.** The bundle has its own embedded Node, not the `node` on the user's `PATH` that actually spawns lifecycle scripts. Two pnpm installations on the same machine (one SEA, one npm-package) therefore disagreed on the cache key, partitioning the side-effects cache and the global virtual store across two Node majors even though both installs would run scripts on the same shell `node`.
-  2. **`engines.runtime` / `devEngines.runtime` pin.** When a project pins a Node version via `devEngines.runtime` (pnpm v11+), pnpm downloads that Node into `node_modules/node/` and uses it to run lifecycle scripts. But the hash still anchored to whichever Node ran pnpm itself, not to the pinned Node — so two installs of the same project with two different runner Nodes would still disagree on the GVS slot path even though scripts run on the same pinned Node.
-
-  Three changes:
-
-  - `@pnpm/engine.runtime.system-node-version` now exports `engineName(nodeVersion?)`. Resolves the version in this order: explicit override → `getSystemNodeVersion()` (which already prefers `node --version` over `process.version` in SEA contexts) → `process.version`.
-  - `@pnpm/deps.graph-hasher` now exports `findRuntimeNodeVersion(snapshotKeys)` — scans an iterable of lockfile snapshot keys for a `node@runtime:<version>` entry and returns its bare version string. `calcDepState` and `calcGraphNodeHash`/`iterateHashedGraphNodes` accept a `nodeVersion?` (in the options bag for the first, as a trailing parameter / ctx field for the others), forwarded to `engineName()`. The default (no override) preserves the pre-change behaviour. The legacy `ENGINE_NAME` constant in `@pnpm/constants` is unchanged so external consumers and existing tests keep working; in non-SEA, non-pinned contexts every value lines up.
-  - Every install-side caller of the graph-hasher (`@pnpm/installing.deps-resolver`, `@pnpm/installing.deps-restorer`, `@pnpm/installing.deps-installer`, `@pnpm/building.during-install`, `@pnpm/building.after-install`, `@pnpm/deps.graph-builder`) now derives the project's pinned runtime via `findRuntimeNodeVersion(Object.keys(graph))` once per invocation and threads it through.
-
-  On upgrade, two one-time GVS slot churns are possible:
-
-  - **SEA-pnpm users** without a runtime pin: slots that previously hashed under the embedded-Node major (e.g. `node26`) now hash under the shell-Node major (e.g. `node24`), matching what pacquet, the npm-published `pnpm` package, and any other pnpm-compatible tool already produce.
-  - **Projects with a `devEngines.runtime` pin**: slots that previously hashed under the runner's Node major now hash under the pinned Node major, matching what the lifecycle scripts will actually run on.
-
-  In both cases the old slots become prune-eligible.
