## 1. Support `nodeLinker: hoisted` on the fresh-lockfile install path (pacquet) Closes #11871. Until now pacquet's `Install::run` hard-refused `nodeLinker: hoisted` without a checked-in lockfile (`ERR_PNPM_…UNSUPPORTED_FRESH_INSTALL_NODE_LINKER`). - Extracted a shared `run_hoisted_linker` helper from the frozen path's hoisted branch (walker → `link_hoisted_modules` → `SymlinkDirectDependencies { link_only: true }` → `pkg_root_by_key` → walker-skip folding), so both install paths run identical logic. - Fresh path now threads `node_linker` + `supported_architectures`, hands `CreateVirtualStore` the real linker (populating `cas_paths_by_pkg_id`), branches on `is_hoisted`, and returns `hoisted_locations` so `.modules.yaml` round-trips. - Removed the guard and the dead `UnsupportedFreshInstallNodeLinker` error variant. Ported upstream's `hoistedNodeLinker/install.ts` into `crates/cli/tests/hoisted_node_linker.rs` (real tests for the core layout, no-lockfile, `externalDependencies`, `autoInstallPeers`, and `hoistingLimits`; the rest stubbed as `known_failures` against `pnpm add`/update (#433) and build-phase (#11870) gaps), and ticked the boxes in `plans/TEST_PORTING.md`. ## 2. Add the `hoistingLimits` setting (pnpm CLI **and** pacquet) Revives the stale #6468 (closes #6457) and brings both stacks to parity. `hoistingLimits` mirrors yarn's `nmHoistingLimits`: `none` (default — hoist as far as possible), `workspaces` (hoist only as far as each workspace package), `dependencies` (hoist only up to each workspace package's direct deps). It was previously a programmatic-only option in pnpm (no config surface) and a pacquet-only raw-map yaml field. **pnpm CLI:** `config/reader` (`types.ts` enum + `Config.ts` + `configFileKey.ts`), `installing/linking/real-hoist`'s new `getHoistingLimits` (mode → the `@yarnpkg/nm` hoister's per-locator border map), and the install/add/recursive command option lists. Tests: `hoistedNodeLinker/install.ts` (`dependencies` mode) + `real-hoist` `getHoistingLimits` unit tests. Changeset included (minor). **pacquet:** replaced the raw-map config with the same enum; added `get_hoisting_limits` (port of `getHoistingLimits`); and **fixed `real-hoist`'s border semantics** — a name in the limits marks a *border* whose descendants stay nested beneath it, not a leaf to block. (The earlier leaf-blocking behavior was the divergence flagged while porting; its unit tests were rewritten to the corrected semantics.)
