Replace the external `@pnpm/registry-mock` (Verdaccio) test dependency with an in-repo, in-process registry that serves package fixtures to **both** the pacquet Rust tests and the pnpm CLI (Jest) tests. No separately managed registry process is needed.
### How it works
- **Fixtures** live at `registry/.fixtures/packages/<name>/<version>/…`, moved verbatim from [`pnpm/registry-mock`](https://github.com/pnpm/registry-mock) (keyed by each `package.json`'s `name`+`version`).
- **`pnpm-registry-fixtures`** builds verdaccio-shaped storage from those fixtures; the in-tree **`pnpm-registry`** crate serves it.
- Files whose names differ only by case (`@pnpm.e2e/with-same-file-in-different-cases`) and `bundleDependencies` trees are composed **in memory** by the builder, since neither can be committed to the working tree.
- **pacquet**: `pacquet-testing-utils`' `TestRegistry` starts the server lazily (once per process) in proxy mode, serving `@pnpm.e2e` fixtures locally and falling through to the npm uplink for real packages (`is-positive`, `is-negative`, …) — matching how registry-mock behaved.
- **pnpm CLI**: the `with-registry` Jest `globalSetup` builds storage from the fixtures via the new `pnpm-registry-prepare` binary (built from source in the Test CI job) and serves it with `pnpm-registry`. `REGISTRY_MOCK_PORT` / `REGISTRY_MOCK_CREDENTIALS` / `getIntegrity` now come from `@pnpm/testing.registry-mock`.
### Result
`@pnpm/registry-mock` is removed from every manifest, the catalog, and `packageExtensions`; `cargo test` / `cargo nextest run` / `just test` and the pnpm CLI Jest suites all run registry-backed tests without launching Verdaccio.
`pnpm install` (non-frozen) used to react to `ERR_PNPM_TARBALL_INTEGRITY` by logging the error, silently re-resolving from the registry, and overwriting the locked integrity. The lockfile's integrity was effectively advisory by default — a compromised registry, proxy, or republished version could substitute attacker-controlled content on a clean machine even though the project shipped a committed `pnpm-lock.yaml`.
Integrity mismatches against the lockfile now fail by default.
The **only** opt-in is **`pnpm install --update-checksums`** — a new flag, narrowly scoped to refreshing the locked integrity values. Mirrors yarn's flag of the same name. A warning still prints when the bypass takes effect so the rewrite stays auditable.
`--force` and `pnpm update` deliberately do **not** bypass the integrity check. They are routine refresh operations; silently overwriting a locked integrity in those flows would erase the protection a committed lockfile is supposed to provide. `--frozen-lockfile` behavior is unchanged. `--fix-lockfile` keeps its documented purpose (filling in missing lockfile entries) and is also not a bypass. Combining `--frozen-lockfile` with `--update-checksums` errors out — frozen mode refuses to rewrite the lockfile, which is exactly what `--update-checksums` is for.
`--update-checksums` also bypasses the resolver's on-disk metadata cache fast path (`pickPackage.ts:271`, `pick_package.rs:531`). Without that, a stale on-disk packument that already contained the pinned version would short-circuit the registry entirely and the flag would silently no-op on dev machines. With the gate, every first-encounter goes through a conditional GET; the in-memory cache is left alone so second-and-onward references within the same install still hit cached fresh data (one network round-trip per *unique* package, not per reference).
## Reported by
Reported privately via the security channel. The reproduction:
1. Publish `example-package@1.0.0` with content `v1` and install with pnpm; lockfile records the `v1` integrity.
2. Replace the registry's tarball+metadata for the same `1.0.0` with content `v2`.
3. On a clean store/cache, run `pnpm install`. Before this fix, pnpm logged `ERR_PNPM_TARBALL_INTEGRITY` but exited 0 with `v2` installed and the lockfile rewritten to the new integrity. After this fix, the same install exits non-zero.
## Prior art
- **npm** ([sebhastian](https://sebhastian.com/npm-err-code-eintegrity/)): hard-fails with `EINTEGRITY`. No dedicated override flag — recovery is `npm cache clean --force`, manually editing the lockfile, or deleting it.
- **yarn** ([Sean C Davis](https://www.seancdavis.com/posts/fix-yarn-integrity-check-failed/)): hard-fails with "Integrity check failed". Has a dedicated **`yarn install --update-checksums`** flag — pnpm now adopts the same name.
## Pacquet parity
Pacquet was already fail-hard on integrity mismatch by default (no auto-repair path to remove). This PR brings the rest of the surface into line so `pnpm install --update-checksums` keeps working when pacquet is the materialization target, and `pacquet install --update-checksums` behaves identically standalone:
- New `--update-checksums` flag on `pacquet install` (`crates/cli/src/cli_args/install.rs`), plumbed through `Install` and `InstallWithFreshLockfile` into the resolver.
- When the flag is set, pacquet skips the frozen-lockfile fast path and routes through the fresh-resolve path so locked integrity values get rewritten from the registry.
- `--frozen-lockfile + --update-checksums` errors with `pacquet_package_manager::frozen_lockfile_with_outdated_lockfile`, mirroring pnpm's `ERR_PNPM_FROZEN_LOCKFILE_WITH_OUTDATED_LOCKFILE`.
- `pacquet_tarball::verify_checksum_error` now carries a help hint pointing at `--update-checksums` and calling out the supply-chain implication, matching the updated pnpm `TarballIntegrityError`.
- The disk fast-path gate is mirrored in `crates/resolving-npm-resolver/src/pick_package.rs:531`, with the flag threaded from `ResolveOptions` → `PickPackageOptions`.
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`).
Closes#11687.
## What
Cache the result of the post-resolution lockfile verification gate (#11583) so repeat installs against an unchanged lockfile skip the per-package registry round trips entirely. Persisted as JSON Lines at `<cacheDir>/lockfile-verified.jsonl`.
The cache layer is policy-neutral. Today there's one verifier (`minimumReleaseAge`); future resolver-side verifiers (jsr trust, attestation, …) plug in by declaring their own `policy` slot and `canTrustPastCheck` comparator — no install-side changes.
## Why
#11583 re-hits the registry on every install for every locked (name, version) pair. On warm/repeat installs where the lockfile hasn't moved, that's a stack of per-package round trips with nothing to show for them. This change makes the steady-state case effectively free without weakening the protection — the gate still runs in full whenever the lockfile changes, any verifier's policy tightens, or no record exists.
## How
### Cache lookup, in order
The cache is **indexed by content hash** so git worktrees with identical lockfile bytes share a cache entry. A secondary path-keyed index drives the same-machine stat shortcut.
1. **`stat()` shortcut** — when a previous record for this exact `lockfilePath` matches today's `size + mtime + inode`, trust the cached hash without reading anything. Zero I/O beyond the stat. Microseconds.
2. **Content lookup** — hash the in-memory lockfile (not the file bytes — we already have the parsed object) and look up by content hash. Catches worktrees (same content, different path) and CI checkouts (same content, reset stat). On hit, append a refreshed path/stat entry so the next install at this path takes the stat shortcut.
3. **Any active verifier rejects the cached `policy`** — run the full gate.
4. **No record** — run the full gate.
The in-memory object is hashed with `hashObject` from `@pnpm/crypto.object-hasher` (streaming, key-order-stable).
### Record shape
```json
{
"lockfile": {
"hash": "<sha256 base64>",
"path": "/abs/path/to/pnpm-lock.yaml",
"size": 154,
"mtimeNs": "1736245123000000000",
"inode": "12345"
},
"verifiedAt": "2026-05-17T...",
"policy": { "minimumReleaseAge": 1440 }
}
```
`policy` is the union of every active verifier's `policy` contribution. Verifiers checking the same logical policy (e.g. `minimumReleaseAge` honored by multiple registries) name it the same and share the slot — no resolver namespacing.
### File semantics
- **Sync fs throughout** — the cache is consulted once before verification fan-out and recorded once after. No concurrent install work to overlap with; keeping the call sites straight-line.
- **JSONL appends are atomic** on POSIX/NTFS, so parallel pnpm processes (monorepo installs, CI matrices sharing a cache) write without coordination. Latest record per `(path, hash)` tuple wins on read.
- **Bounded file** — capped at ~1000 entries; compaction is triggered by a single `stat()` of the cache file (1.5 MiB byte budget) so we never parse the file on the steady-state path. When triggered, the tail is rewritten via tempfile + rename.
- **No record on rejection** — a failing verification deliberately doesn't write a record; the next install must rerun the gate.
- **Single hash per install** — the in-memory hash is computed lazily and reused: `tryLockfileVerificationCache` returns the precomputed stat+hash to `recordVerification` on a miss, and the stat-shortcut hit forwards the cached record's hash unchanged.
## Plumbing
The verifier contract changed alongside the cache to make this composable without install-side knowledge of each policy:
- **`@pnpm/resolving.resolver-base`** — `ResolutionVerifier` is now `{ verify, policy, canTrustPastCheck }` (was a bare function in #11583). Each resolver-side verifier owns its policy snapshot and the comparator that decides whether a cached policy is still trustworthy.
- **`@pnpm/resolving.npm-resolver`** — `createNpmResolutionVerifier` returns the new shape: `policy: { minimumReleaseAge }`, `canTrustPastCheck` reads `minimumReleaseAge` from the merged cached bag.
- **`@pnpm/resolving.default-resolver`** — `createResolutionVerifier` (singular, returning a combined function) → `createResolutionVerifiers` (plural, returning a `ResolutionVerifier[]`). No combinator; each verifier handles its own protocol short-circuit inside `verify`, so dispatch happens naturally at the install side.
- **`@pnpm/installing.client`** — `Client.verifyResolution?` → `Client.resolutionVerifiers: ResolutionVerifier[]`. Same rename propagates through `@pnpm/store.connection-manager`, `@pnpm/testing.temp-store`, and `StrictInstallOptions`.
- **`@pnpm/installing.deps-installer`** — new `verifyLockfileResolutionsCache.ts` (`tryLockfileVerificationCache` + `recordVerification`). `verifyLockfileResolutions` takes the verifier list plus `cacheDir` + `lockfilePath` as flat options; the cache fires when both are present, otherwise the gate runs without memoization. The dedup key for in-flight candidates includes a serialization of `resolution` so two entries sharing a (name, version) but pinned via different protocols don't collapse.
Breaking but safe — `@pnpm/resolving.npm-resolver` hasn't been released since #11583 introduced the verifier abstraction, so no downstream consumer is on the old shape.
## Tests
- **17 unit tests** in `verifyLockfileResolutionsCache.ts`: cache miss/hit, stat shortcut, size mismatch falling through to hash lookup, hash-fallback on reset stat, content change with matching size, stricter/weaker policy, missing-field policy rejection, multi-verifier policy merge (shared field stored once), worktree case (same content, different path), JSONL append semantics, malformed-line tolerance.
- **12 integration tests** in `verifyLockfileResolutions.ts`: dedup of peer/patch-suffix variants, distinct-resolution dedup at the same (name, version), stable violation ordering, the 20-entry cap, multi-verifier fan-out (first failure wins), cache short-circuit on a passing run, no cache write on a rejecting run, empty-verifier-list passthrough.
- **1 e2e test** in `pnpm/test/install/minimumReleaseAge.ts`: bundled CLI plumbing — install once to seed the lockfile, enable `minimumReleaseAge` + `cacheDir`, install again, assert the cache file lands at `<cacheDir>/lockfile-verified.jsonl` with the documented record shape.
- Existing `minimumReleaseAge` (13) and `frozenLockfile` (12) suites still pass.
Closes#10438.
## What
Re-verify every entry in `pnpm-lock.yaml` against the policies the resolver chain was configured with — today: `minimumReleaseAge` in strict mode — right after the lockfile is loaded from disk and before any tarball is fetched. A locked version that fails the policy aborts the install with `ERR_PNPM_MINIMUM_RELEASE_AGE_VIOLATION`; `minimumReleaseAgeExclude` is honored.
## Why
The policy only fires while pnpm is *choosing* a version. Once a version is pinned in the lockfile — e.g. a developer disabled the policy locally and committed a fresh dependency, or a CI cache restored a stale lockfile — every later `pnpm install` (including `--frozen-lockfile` and `pnpm fetch`) installs it without re-checking, which defeats the supply-chain protection the setting is supposed to provide.
The threat model is **a lockfile someone else resolved**, not local resolution: local resolution is already covered by the resolver's own per-version filter. bun fixed the same shape of bug in [oven-sh/bun#30526](https://github.com/oven-sh/bun/pull/30526); this PR is the pnpm side.
## How
The fix introduces a generic `ResolutionVerifier` abstraction in the resolver chain — each resolver factory can ship a sibling verifier factory, exactly the way each resolver ships a `resolve` function. Today there's one verifier (npm); the shape leaves room for future ones (jsr, attestation-based, etc.) without changing the install-side interface.
- **`@pnpm/resolving.resolver-base`** exports the `ResolutionVerifier` / `ResolutionVerification` types — the shared contract.
- **`@pnpm/resolving.npm-resolver`** exports `createNpmResolutionVerifier`. Returns `undefined` when no policy is active, so callers can cheaply decide whether to iterate at all. When active, it inspects each lockfile entry, handles `minimumReleaseAgeExclude`, routes through named-registry prefixes (built-ins like `gh:` merged in), and uses `fetchFullMetadataCached` to fetch full registry metadata — decoupled from the resolver pipeline so neither `peekManifestFromStore` nor abbreviated metadata can hide the publish timestamp.
- **`@pnpm/resolving.default-resolver`** exports `createResolutionVerifier`, a combinator that asks each underlying verifier (today: npm) if it has work and returns `undefined` when none does. Designed so that adding more verifiers later doesn't change the install side.
- **`@pnpm/installing.client`** exposes `verifyResolution` on `Client`, built from the same `fetchFromRegistry` / `getAuthHeader` the resolver chain already uses — **no second fetcher is constructed**.
- **`@pnpm/store.connection-manager`** and **`@pnpm/testing.temp-store`** surface `verifyResolution` alongside the store controller they hand back, so it reaches `mutateModules` through the existing plumbing.
- **`@pnpm/installing.deps-installer`** gains one option on `StrictInstallOptions`: `verifyResolution?: ResolutionVerifier`. `mutateModules` invokes `verifyLockfileResolutions(ctx.wantedLockfile, opts.verifyResolution)` **once**, right after `getContext` returns the on-disk lockfile and before any path branches. When the verifier is `undefined`, the call is a no-op. The iteration is policy-neutral: dedupes by `(name, version)`, applies `pLimit(16)`, sorts violations stably, caps the printed list at 20 with an `…and N more` summary, throws a `PnpmError` carrying the verifier-supplied error code.
The error includes a recovery hint that points at `pnpm clean --lockfile` followed by `pnpm install` — the safe way to throw away a poisoned lockfile and rebuild from fresh resolution.
## Tests
- **9 unit tests** for `verifyLockfileResolutions` against a mock `ResolutionVerifier` — dedup, aggregation, stable ordering, the 20-entry cap, no-op behavior, the verifier-supplied error code surfacing in `PnpmError`.
- **13 integration tests** in `installing/deps-installer/test/install/minimumReleaseAge.ts` via the real `install()` entry — `testDefaults()` wires `verifyResolution` from `createTempStore` → `createClient`, so the npm verifier runs end-to-end at the install boundary. Covers the rejection scenario, `minimumReleaseAgeExclude`, the strict-mode toggle, the existing `minimumReleaseAge` resolver-side suite, and a `pnpm add` scenario where a pre-existing entry would otherwise survive resolution.
- **3 e2e tests** in `pnpm/test/install/minimumReleaseAge.ts` against the bundled CLI: rejection path with the right `ERR_PNPM_*` code and `pnpm clean --lockfile` hint in output, `minimumReleaseAgeExclude` honored, and the strict-off path (which now requires an explicit `minimumReleaseAgeStrict: false` since the config reader auto-enables strict mode when `minimumReleaseAge` is set).
- Existing `frozenLockfile` suite (12 tests) and npm-resolver suite (179 tests) still pass.

For git-hosted tarballs (`codeload.github.com` / `gitlab.com` / `bitbucket.org`) the fetcher dropped the integrity it computed while downloading, so the lockfile only ever stored the URL. A compromised git host or man-in-the-middle could serve a substituted tarball on subsequent installs and pnpm would install it — the lockfile had no hash to compare against.
This pins the SHA-512 SRI of the raw tarball in the lockfile, in the same `sha512-<base64>` form npm-registry tarballs use. The only difference is the source: for npm we pass through `dist.integrity`, for git we compute it locally from the downloaded buffer. Subsequent installs validate the download against that integrity in the worker (`addTarballToStore` → `parseIntegrity` → hash compare), so a tampered tarball fails with `TarballIntegrityError`.
## Why git-hosted stays on `gitHostedStoreIndexKey`
The lockfile pins integrity for security, but the *store key* for git-hosted resolutions stays on `gitHostedStoreIndexKey(pkgId, { built })` rather than collapsing under the integrity-based key. Reason: git-hosted tarballs are post-processed (`preparePackage` / `packlist`), so the cached file set depends on whether build scripts ran during fetch. The integrity-only key would fold the built and not-built variants into a single slot, letting one overwrite the other and serving the wrong content if `ignoreScripts` was toggled between runs. Keeping git-hosted on the existing key shape preserves that dimension; the integrity is still validated on every fresh download.
## How the routing stays clean
The naive way to express "use gitHostedStoreIndexKey for git-hosted, integrity key for npm" is to call `isGitHostedPkgUrl(resolution.tarball)` everywhere a store key is computed — fragile, scattered, and easy to forget when adding new readers (Copilot caught two of those during review). Instead, a typed annotation: `TarballResolution` gets an optional `gitHosted: boolean` field. The git resolver sets it; the lockfile loader (`convertToLockfileObject`) backfills it for entries written by older pnpm versions; `toLockfileResolution` carries it through on serialize. Every consumer reads `resolution.gitHosted` directly. URL detection lives in exactly two places — the resolver and the loader — instead of seven.
## Changes
### Security fix
- `fetching/tarball-fetcher/src/gitHostedTarballFetcher.ts` — return the `integrity` that the inner remote-tarball fetch already computed (was being silently dropped by the destructure).
### Lockfile schema (additive)
- `@pnpm/lockfile.types` and `@pnpm/resolving.resolver-base` — `TarballResolution` gains optional `gitHosted: boolean`.
- `@pnpm/resolving.git-resolver` — sets `gitHosted: true` on every git-hosted tarball it produces.
- `@pnpm/lockfile.fs` (`convertToLockfileObject`) — backfills the field on load for older lockfiles via inlined URL detection.
- `@pnpm/lockfile.utils` (`toLockfileResolution`, `pkgSnapshotToResolution`) — preserve / read the field.
### Store-key consumers (now one-line typed reads, dropped the URL-sniffing dep)
- `installing/package-requester` (`getFilesIndexFilePath`)
- `store/pkg-finder` (`readPackageFileMap`)
- `modules-mounter/daemon` (`createFuseHandlers`)
- `building/after-install` (side-effects-cache lookup + write)
- `store/commands/storeStatus`
- `installing/deps-installer` (agent-mode store-controller wrapper)
### Fetcher routing
- `fetching/pick-fetcher` — `pickFetcher` prefers `resolution.gitHosted`; URL fallback retained for ad-hoc resolutions.
### Tests
- New integrity-validation test in `tarball-fetcher` (mismatched `integrity` on the resolution must throw `TarballIntegrityError`).
- New git-hosted lookup test in `pkg-finder` asserting routing through `gitHostedStoreIndexKey` even when integrity is present.
- New `toLockfileResolution` test asserting `gitHosted: true` flows through serialization.
- `fromRepo.ts` lockfile snapshot updated for the now-pinned integrity + `gitHosted: true`.
- `git-resolver` tests updated to assert `gitHosted: true` in produced resolutions.
This is consistent with #9358, but implements support for the GitHub Packages npm registry and, more broadly, for vlt-style https://docs.vlt.sh/cli/registries for any registry.
This PR adds a built-in gh: specifier that resolves against the GitHub Packages npm registry, plus a namedRegistries config key so a project can map its own aliases to arbitrary registries. A project can mix public npm packages and private GitHub Packages (or self-hosted) ones without applying a scope-wide registry override to every @scope/* package.
- pnpm add gh:@acme/private writes "@acme/private": "gh:^1.0.0" and resolves from https://npm.pkg.github.com/.
- pnpm add gh:@acme/private@^1.0.0 (with or without an alias) is also supported. Aliased form writes "my-alias": "gh:@acme/private@^1.0.0".
- Auth comes from the existing per-URL .npmrc mechanism, e.g. //npm.pkg.github.com/:_authToken=${GITHUB_TOKEN}. No new auth surface.
- @github is intentionally not defaulted to https://npm.pkg.github.com/ - hardcoding that would hijack installs of the public @github/* packages on npmjs.org (e.g. @github/relative-time-element) for users without a scope-wide override. Use gh: to install from GitHub Packages, or configure @github:registry=... yourself if that's really what you want.
- Additional named registries (a self-hosted proxy, GitHub Enterprise Server, etc.) can be configured in pnpm-workspace.yaml:
```yml
namedRegistries:
gh: https://npm.pkg.github.example.com/ # optional: overrides the built-in `gh` alias for GHES
work: https://npm.work.example.com/
```
- Then work:@corp/lib@^2.0.0 resolves against https://npm.work.example.com/, and the built-in gh alias can be redirected to a GHES host.
- Env-var substitution (${VAR}) is supported in namedRegistries values, mirroring the .npmrc convention.
- Reserved alias names (npm, jsr, github, workspace, catalog, file, git, http, https, link, patch, and related git host shorthands) cannot be redefined as user-named registries - the resolver throws ERR_PNPM_RESERVED_NAMED_REGISTRY_ALIAS at startup rather than silently shadowing another protocol. Malformed URLs throw ERR_PNPM_INVALID_NAMED_REGISTRY_URL at startup too, instead of failing as a confusing 404 during resolution.
- On publish, createExportableManifest strips any named-registry prefix (both the built-in gh: and any user-configured alias) so npm and yarn consumers can still resolve the dependency via their own scope-registry configuration - mirroring the user-facing requirement when installing such a dep without the prefix.
The prefix is gh: rather than github: because github: is reserved by npm-package-arg / hosted-git-info as a git host shorthand (e.g. github:owner/repo) - reusing it would be a deviation from the specs used by the npm CLI. gh: is shorter, matches vlt's convention, and cannot collide with any existing npm scheme.
Unlike jsr:, gh: (and any other named-registry alias) does not rewrite the package name - gh:@acme/foo resolves @acme/foo from the GitHub Packages registry as-is. This also means npm/yarn consumers see the original name after the prefix is stripped on publish.

* 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(sbom): resolve licenses for git-sourced dependencies
`readPackageFileMap` did not handle `type: 'git'` resolutions, causing
`pnpm sbom` to emit NOASSERTION and `pnpm licenses` to throw for any
dependency installed from a git URL.
Closes#11260
* fix: add missing store.cafs devDep, test tsconfigs, and size field
- Add @pnpm/store.cafs devDependency and tsconfig reference to
license-scanner so CI typecheck resolves the PackageFilesIndex import
- Add test/tsconfig.json to pkg-finder so CI typechecks the new tests
- Add required `size` field to PackageFileInfo test fixtures
* fix: replace spellcheck-failing test strings
* fix: use spellcheck-safe integrity string in test
* style: fix import sort in pkg-finder test
* fix(sbom): use packageIdFromSnapshot to match store index keys
The SBOM used `snapshot.id ?? depPath` as the package ID, which
includes the package name prefix (e.g. `left-pad@git+https://...`).
The store index stores git packages under just the git URL without
the name prefix. Use `packageIdFromSnapshot` which strips the prefix,
matching how the licenses command already does it.
Also fixes test store keys to match the real installer layout so the
mismatch would have been caught by tests.
* refactor: move git resolution check after tarball check
Tarball resolutions are more common than type: 'git', so check them
first. Per review feedback from @zkochan.
## Summary
Adds an opt-in **pnpm agent** server that resolves dependencies server-side and streams only the files missing from the client's content-addressable store.
- **`@pnpm/agent.server`** — multi-process HTTP server (Node.js `cluster`) with SQLite-backed metadata and file caches
- **`@pnpm/agent.client`** — streams an NDJSON response, dispatches worker threads to fetch files while the server is still resolving
- **New config**: `agent` in `pnpm-workspace.yaml` (opt-in)
## How it works
1. Client reads integrity hashes from its local store index
2. Sends `POST /v1/install` with dependencies + store integrities
3. Server resolves the dependency tree using pnpm's `install({ lockfileOnly: true })`, with a SQLite-backed `PackageMetaCache` for fast repeat resolution
4. As each package resolves, a wrapped `storeController.requestPackage` looks up its files and immediately streams digests the client is missing (NDJSON `D` lines)
5. Client reads the stream line by line; digest batches fill up and dispatch worker threads to `POST /v1/files` — file downloads overlap with server-side resolution
6. After resolution, server sends index entries (`I` lines) and lockfile (`L` line)
7. Client writes index entries to store, then runs headless install with a wrapped `fetchPackage` that calls `readPkgFromCafs` with `verifyStoreIntegrity: false` (files are trusted from the agent)
8. `/v1/files` response is gzip-streamed (274MB → ~80MB) — server pipes through `createGzip`, worker pipes through `createGunzip`, parsing and writing files to CAFS as data arrives
## Performance
1351-package project, cold local store, warm server (localhost):
| Scenario | Time |
|----------|------|
| Vanilla pnpm install (cold OS cache) | ~48s |
| Vanilla pnpm install (warm OS cache) | ~34s |
| With pnpm agent (consistent) | **~33s** |
### Key optimizations
1. **SQLite metadata cache** — server-side resolution drops from ~3.4s to ~0.9s
2. **SQLite file store** — consistent read performance regardless of OS file cache state
3. **Streaming `/v1/install`** — file digests stream during resolution, downloads start before resolution finishes
4. **Gzip-streamed `/v1/files`** — whole-stream gzip (274MB → ~80MB), significant savings on remote servers
5. **Worker-thread streaming HTTP** — workers pipe gzip → parse → write to CAFS as data arrives, no buffering
6. **No rehashing** — server-provided digests used directly, skipping 33K SHA-512 computations
7. **No re-verification** — wrapped `fetchPackage` calls `readPkgFromCafs` with `verifyStoreIntegrity: false`
8. **Direct `writeFileSync` with `wx`** — no stat + temp + rename
9. **Pre-packed msgpack** — server sends raw store index buffers, client writes directly to SQLite
10. **WAL checkpoint** — ensures store index entries written by agent are visible to headless install's worker threads
## Usage
Start the server:
```bash
node agent/server/lib/bin.js
```
Configure in `pnpm-workspace.yaml`:
```yaml
agent: http://localhost:4873
```
Skips the minimumReleaseAge maturity check when the registry metadata
lacks the "time" field, instead of throwing ERR_PNPM_MISSING_TIME.
Defaults to true, and prints a warning once per affected package.
When pnpm self-updates via the headless install path, the install
directory was not registered in the store's project registry. This
caused `pnpm store prune` to treat its global virtual store packages
as unreachable and remove them, breaking the global pnpm binary.
Register the install dir after headless install in installPnpmToGlobalDir
- Adds a new `minimumReleaseAgeStrict` setting (default: `false`)
- When `false` (default), pnpm falls back to versions that don't meet the `minimumReleaseAge` constraint if no mature versions satisfy the range being resolved
- Set to `true` to preserve the previous strict behavior (error when no mature version matches)
* refactor(config): split Config interface into settings + runtime context
Create ConfigContext for runtime state (hooks, finders, workspace graph,
CLI metadata) and keep Config for user-facing settings only. Functions
use Pick<Config, ...> & Pick<ConfigContext, ...> to express which fields
they need from each interface.
getConfig() now returns { config, context, warnings }. The CLI wrapper
returns { config, context } and spreads both when calling command
handlers (to be refactored to separate params in follow-up PRs).
Closes#11195
* fix: address review feedback
- Initialize cliOptions on pnpmConfig so context.cliOptions is never undefined
- Move rootProjectManifestDir assignment before ignoreLocalSettings guard
- Add allProjectsGraph to INTERNAL_CONFIG_KEYS
* refactor: remove INTERNAL_CONFIG_KEYS from configToRecord
configToRecord now accepts Config and ConfigContext separately, so
context fields are never in scope. Only auth-related Config fields
(authConfig, authInfos, sslConfigs) need filtering.
* refactor: eliminate INTERNAL_CONFIG_KEYS from configToRecord
configToRecord now receives the clean Config object and explicitlySetKeys
separately (via opts.config and opts.context), so context fields are
never in scope. main.ts passes the original split objects alongside
the spread for command handlers that need them.
* fix: spelling
* fix: import sorting
* fix: --config.xxx nconf overrides conflicting with --config CLI flag
When `pnpm add` registers `config: Boolean`, nopt captures
--config.xxx=yyy as the --config flag value instead of treating it
as a nconf-style config override. Fix by extracting --config.xxx args
before nopt parsing and re-parsing them separately.
Also rename the split config/context properties on the command opts
object to _config/_context to avoid clashing with the --config CLI option.
