Three coordinated changes that close the silent-bypass gap in loose `minimumReleaseAge` mode AND the discover-by-loop UX problem in strict mode (#10488), plus a parallel hardening of the lockfile verifier:
1. **Auto-collect into `minimumReleaseAgeExclude` (loose mode)** — fresh resolutions that fall back to a version newer than the cutoff are auto-recorded into the workspace manifest's `minimumReleaseAgeExclude`. A single info message lists what was persisted. The workspace manifest writer dedupes against existing entries.
2. **Lockfile verifier runs in loose mode too** — `createNpmResolutionVerifier` no longer gates on `minimumReleaseAgeStrict`. With auto-collect keeping the exclude list explicit, every accepted-immature pin must be on the list — same contract strict mode enforces. Lockfiles produced under a weaker (or absent) policy that still hold immature entries are rejected the same way strict mode would.
3. **Strict mode prompts on the aggregate set instead of throwing on the first** — the resolver always collects every immature direct and transitive in one pass; the install command's `handleResolutionPolicyViolations` checkpoint decides what to do with the set. Interactive (TTY) prompts the user once with the full list (default = No) and asks whether to add them all to `minimumReleaseAgeExclude` and proceed. Approve → install continues, persisted at the end. Decline → resolution aborts before the lockfile, package.json, or modules dir is touched. Non-interactive (CI) keeps `ERR_PNPM_NO_MATURE_MATCHING_VERSION` as the exit code but lists every offending entry instead of just the first one the resolver happened to hit.
4. **The lockfile verifier now also covers `trustPolicy: 'no-downgrade'`.** The same post-resolution gate that re-checks `minimumReleaseAge` on lockfile entries now re-runs `failIfTrustDowngraded` for every npm-registry entry whose name isn't on `trustPolicyExclude`. The two checks share a single full-metadata fetch per package, so the extra coverage doesn't cost an extra round trip when both policies are active. Resolver-time trust checks still run as before — this just closes the gap when an entry bypasses resolution (peek path, `--frozen-lockfile`, restored CI cache).
The steady-state flows:
- **Loose mode, `pnpm add foo@immature`**: lockfile clean, verifier no-op, resolver picks via lowest-version fallback, `foo@immature` lands in `minimumReleaseAgeExclude`, install succeeds. Subsequent `pnpm install --frozen-lockfile` in CI verifies against the populated list and succeeds.
- **Strict mode (interactive), security bump to `next@15.5.9`**: resolver collects `next@15.5.9` AND every immature `@next/swc-*@15.5.9` shim. pnpm prompts once with the full list. User approves → install completes, all entries persisted in `pnpm-workspace.yaml`. CI then runs the populated config cleanly.
- **Strict mode (non-interactive / CI)**: aborts with `ERR_PNPM_NO_MATURE_MATCHING_VERSION` listing every immature entry's `name@version` and publish time — no more discover-by-loop dance.
- **Teammate commits a poisoned lockfile**: single-policy batches reject with `ERR_PNPM_MINIMUM_RELEASE_AGE_VIOLATION` (or `ERR_PNPM_TRUST_DOWNGRADE`); a batch that trips both policies escalates to the generic `ERR_PNPM_LOCKFILE_RESOLUTION_VERIFICATION` and lists each entry's per-policy code in the breakdown.
### Implementation
- The npm resolver always falls back to the lowest matching version when no mature version satisfies the range, and flags the result with `ResolveResult.policyViolation` instead of throwing `NO_MATURE_MATCHING_VERSION`. `deferImmatureDecision` and `strictPublishedByCheck` are gone — every caller (install, dlx, outdated, self-update) inspects the violation and decides what to do.
- `policyViolation` flows from `ResolveResult` → `PackageResponse.body.policyViolation` → a shared accumulator in `ResolutionContext` → the `resolutionPolicyViolations` field on `resolveDependencyTree`'s return → out through `mutateModules` / `addDependenciesToPackage` to the install command.
- The violation type lives in `@pnpm/resolving.resolver-base` as `ResolutionPolicyViolation`; the npm resolver exports the two built-in codes (`MINIMUM_RELEASE_AGE_VIOLATION_CODE`, `TRUST_DOWNGRADE_VIOLATION_CODE`) as constants so consumers reference one source of truth.
- `handleResolutionPolicyViolations` runs between `resolveDependencyTree` and `resolvePeers` — the resolver-agnostic checkpoint where the install command's plan prompts (TTY) or aborts (no-TTY) with the full violation list.
- `setupPolicyHandlers` (in `installing/commands/src/policyHandlers.ts`) composes per-policy handlers behind a uniform plan interface: each handler has its own `handleResolutionPolicyViolations` (filter by code, decide what to do) and `pickManifestUpdates` (return a typed `WorkspaceManifestPolicyUpdates` patch the install command spreads into `updateWorkspaceManifest`). Today the only registered handler is `createMinimumReleaseAgeHandler` — strict + TTY prompts via `enquirer`, strict no-TTY throws `ERR_PNPM_NO_MATURE_MATCHING_VERSION` with every entry listed, loose mode auto-persists at the tail. Strict + `--no-save` is rejected up-front via `ERR_PNPM_STRICT_MIN_RELEASE_AGE_REQUIRES_SAVE`. Future policies plug in via a sibling factory + push into the handlers list, with no changes to `installDeps.ts` / `recursive.ts`.
- `installDeps` / `recursive` drain `pickManifestUpdates` after install and spread the patch into `updateWorkspaceManifest`. Plain `pnpm install` (no `--update`, no params) now still updates the workspace manifest when any handler contributes a patch. The `install` command's CLI schema gained `save: Boolean` so `--no-save` actually flows through to `opts.save = false` instead of being silently dropped by nopt.
- `makeResolutionStrict` (in `installing/client`) wraps a `ResolveFunction` and rethrows any `policyViolation` as a `PnpmError`. Used by `dlx` and `self-update` under strict `minimumReleaseAge` OR `trustPolicy: 'no-downgrade'`, since one-shot callers have nowhere to defer a violation to. Violation-code → error-code mapping lives in one place so future violation kinds get consistent UX.
- `createNpmResolutionVerifier` extends its check to `trustPolicy: 'no-downgrade'` — same per-entry fan-out, same cache key, sharing the full-metadata fetch with the maturity check. Trust-fetch errors now propagate up so the violation reason carries the underlying message (network code, 404 detail) instead of a generic "metadata is unavailable".
- `verifyLockfileResolutions`'s aggregate throw uses the per-policy code when every violation in the batch shares it, and escalates to a generic `LOCKFILE_RESOLUTION_VERIFICATION` (with per-entry codes in the breakdown) for mixed batches.
- The pnpm agent path refuses installs under `trustPolicy: 'no-downgrade'` (`ERR_PNPM_TRUST_POLICY_INCOMPATIBLE_WITH_AGENT`) — the agent has no server-side counterpart to that check yet, so silently allowing it would land a lockfile the local verifier would later reject. `minimumReleaseAge` is forwarded to the agent and enforced server-side, so that combination is fine.
### Pacquet parity
Pacquet only carries a stub reference to `minimumReleaseAgeExclude` (see `pacquet/crates/package-manager/src/version_policy.rs`); the broader `minimumReleaseAge` and `trustPolicy` policies aren't ported yet, so this feature is outside pacquet's current surface area. It'll come along when pacquet ports the policies.
### Closes
- Closes#10488 (resolves the discover-by-loop dance for security bumps without needing `withTransitives`).
* chore: upgrade @typescript/native-preview to 7.0.0-dev.20260421.2
- Add explicit `types: ["node"]` to the shared tsconfig because tsgo
20260421 no longer auto-acquires `@types/*` from `node_modules`.
- Refactor test files to explicitly import jest globals (`describe`,
`it`, `test`, `expect`, `beforeEach`, etc.) from `@jest/globals`
instead of relying on `@types/jest` ambient declarations. Under the
new tsgo build, `import { jest } from '@jest/globals'` shadows the
ambient `jest` namespace, breaking `@types/jest`'s `declare var
describe: jest.Describe;` globals.
- Add `@jest/globals` to each package's devDependencies where tests
now import from it, and add `@types/node` to packages that need it
but were relying on hoisted resolution.
- Replace `fail()` calls with `throw new Error(...)` since `fail` is
no longer globally available.
* chore: fix remaining tsgo type-strictness errors
- Strip `as <PnpmType>` casts on objects passed to toMatchObject /
toStrictEqual / toEqual; @jest/globals rejects the typed objects
(which include AsymmetricMatchers) vs. the repo-specific type.
- Type `jest.fn<...>()` explicitly where the mock's signature matters
for toHaveBeenCalledWith.
- Replace `beforeEach(() => X)` with `beforeEach(() => { X })` so the
return value is void, as the stricter jest typing requires.
- Use `expect.objectContaining({...})` in one place where the full
expected object triggered stricter type resolution.
- Cast `prompt.mock.calls` arg through `as unknown as Record<...>[]`
for patch.test.ts's nested-array matchers.
- Fix off-by-one `<reference path>` in pnpm/test/getConfig.test.ts
that only surfaced now.
- Move `@jest/globals` from devDependencies to dependencies in the
two `__utils__` packages that import it from `src/`.
- Clean up unused imports from the @jest/globals migration.
* chore: address Copilot review on #11332
- Move misplaced `@jest/globals` imports to the top import block in
checkEngine, run.ts, and workspace/root-finder tests where the
script dropped them below executable code.
- Replace `try { await x(); throw new Error('should have thrown') } catch`
in bins/linker, lockfile/fs, and resolving/local-resolver tests with
`await expect(x()).rejects.toMatchObject({...})`. The old pattern
swallowed an unrelated `throw` if the under-test call silently
succeeded, which would fail on the catch-block assertion with a
misleading message.
## Summary
- pnpm installing a Node.js runtime (`node@runtime:<ver>`, `pnpm env use`, `pnpm runtime set node`) no longer extracts the bundled `npm`, `npx`, and `corepack`. These make up ~2,800 of ~5,800 files in a typical Node.js archive, so skipping them materially reduces hashing, CAS writes, SQLite index inserts, and import/link work.
- Users who still need `npm` can install it as a separate package.
## How
A new optional `ignoreFilePattern` (regex source string, serializable across the worker boundary) threads through `FetchOptions` → `tarball-fetcher` → `@pnpm/worker` → `cafs.addFilesFromTarball`. `cafs.addFilesFromTarball` now accepts a per-call ignore on top of the existing cafs-level `ignoreFile`; the two are combined.
`@pnpm/fetching.binary-fetcher` defines the Node-specific regex and applies it when `opts.pkg.name === 'node'`:
- Tarball path: sets `ignoreFilePattern`.
- Windows zip path: new `ignoreEntry?: RegExp` on `AssetInfo`; `extractZipToTarget` strips the `basename/` prefix and skips matching entries before `zip.extractEntryTo`.
`@pnpm/engine.runtime.node-resolver`'s `getNodeBinsForCurrentOS` drops `npm`/`npx` so pnpm no longer creates shims for bins that no longer exist.
## Breaking change
Shipping in v11. After this lands, `pnpm runtime set node` / `node@runtime:<version>` no longer puts `npm`, `npx`, or `corepack` on `$PATH`. Scripts that call them directly will need to install npm separately.
Library packages had `prepublishOnly: pn compile`, which expands to
`tsgo --build && pn lint --fix`. During `pn release` that runs eslint
against ~150 packages for no benefit — the code has already been linted
in CI and the release flow's upfront compile has already built dist/.
Switch lib prepublishOnly to a bare `tsgo --build` so the safety-net
compile stays but the per-package eslint cost is gone.
* fix: ensure PNPM_HOME/bin is in PATH during pnpm setup
When upgrading from old pnpm (global bin = PNPM_HOME) to new pnpm
(global bin = PNPM_HOME/bin), `pnpm setup` would fail because the
spawned `pnpm add -g` checks that the global bin dir is in PATH.
Prepend PNPM_HOME/bin to PATH in the spawned process env so the
check passes during the transition.
