feat(deps-restorer): store other platforms' archives and their dependencies on every install - #17735
This is the last part of supportedArchitectures for platform variants (pnpm/rfcs#69, "Install"). Every install, and pnpm fetch, now stores the archives the listed platforms keep together with the packages those archives depend on. Nothing extra is linked.
One store-only pass. It runs after the virtual store is materialized, warm or cold, so a platform added to supportedArchitectures is picked up by the next install, including one that reuses every slot. pnpm fetch runs the same frozen install pipeline, so it follows the same rule.
The walk (current_lockfile::platform_archives). For each listed platform, it starts at the installed projects. For a package with variants, it keeps every archive that platform fetches (VariationsResolution::fetched_for, the same selection the fetch rule uses). It then follows each kept archive's dependencies, from the variant's own <name>@<version>/variants/<tag> snapshot when there is one, and otherwise from the version's. So a package reachable only through an archive no listed platform keeps is never fetched. Archives and packages the install already links are skipped.
The fetch (InstallPackageBySnapshot::store_archives). It downloads the kept archives concurrently, bounded by the client's per-host limit, through the existing tarball path. An archive the store already holds is read from the store index, not downloaded again.
No extra work otherwise. Without supportedArchitectures, or when it lists only the platform the install links for ([current]), the pass returns before walking.
Consolidation. This replaces the cold-path-only fetch from feat(deps-restorer): fetch the variants supportedArchitectures needs into the store #17684, which ran only when a package was downloaded, so there is one path for the archives of other platforms. SnapshotSelection gains platform_lockfile, the whole wanted lockfile with every variant's own snapshot, because the materialized closure has those snapshots wired to the linked platform.
Test plan
Unit tests for platform_archives:
another platform's variant is kept with its own snapshot's dependency;
the linked platform keeps nothing extra;
a platform no variant serves keeps the any archive and no variant's own dependency.
The fetch rule's stored_archives tests moved alongside the walk and still pass.
End-to-end against an in-process pnpr. The store is emptied after resolving, because the resolver prefetches every package it resolves, so only the install itself puts files in the store.
with [current, <foreign>], a frozen install stores the foreign variant and its dependency, and links neither;
a warm install without supportedArchitectures stores only the linked archive; adding the foreign platform and reinstalling from the lockfile then stores its variant and dependency;
pnpm fetch with two platforms stores both variants and the foreign variant's dependency.
deps-restorer, package-manager, and the pnpm-cli pnpr_install, install, fetch, optional, supported_architectures, frozen, hoisted, repeat and up_to_date suites: 3049 of 3054 pass. The 5 failures also fail locally on main.
The v11 compatibility set (pnpm_compatibility, peer_convergence, repeat_install_oracle, repeat_install_read_set, injected_freshness_matrix) with a v11 bundle: 409 of 409 pass.
Lints: rustfmt, clippy, dylint, crate-layers check and the prose lint are clean.

Summary by CodeRabbit
New Features
Installs and pnpm fetch store archives and dependencies for other platforms listed in supportedArchitectures, without linking them into the current installation.
Platforms added later are considered on the next install or fetch, even when packages are already installed.
Archives for unrunnable optional dependencies and failed downloads are skipped. Dependencies from Git repositories and Git-hosted tarballs are not stored for other platforms.
Documentation
Updated the supportedArchitectures guidance to describe platform archive and dependency fetching behavior.
The install pipeline selects archives and dependencies for listed platforms and stores them without linking. Installs and pnpm fetch check for these archives, including after a platform is added to an existing installation.
Changes: Supported-platform archive storage
Layer / File(s)
Summary
Archive selection and dependency traversal pnpm/crates/deps-restorer/src/current_lockfile*, pnpm/crates/deps-restorer/src/current_lockfile/platform_archives/*, pnpm/crates/deps-restorer/src/current_lockfile/variant_snapshots.rs
The lockfile traversal selects archives for requested platforms. It follows variant-specific snapshots when available, applies platform and optional-dependency rules, skips the linked archive, and deduplicates selected archives.
Snapshot selection now carries the wanted lockfile and selected groups. The virtual-store pipeline selects archives for other listed platforms and stores them without linking. Archive fetching processes selected archive entries and package metadata.
Install and fetch coverage; documentation pnpm/crates/cli/tests/suite/pnpr_install/supported_architectures_link.rs, .changeset/pnpm-supported-architectures-extra-deps.md, pnpm/docs/registries.md
Tests cover archive and dependency storage during installs and fetch, including warm installs and production installs. The changeset and documentation describe the behavior and exclusions.
HEAD and main are measured on the same runner. The tolerance is 5% of the main median or 2 ms, whichever is larger. A regression requires both the median slowdown and the gap between the fastest retained HEAD sample and slowest retained main sample to exceed this tolerance, after trimming up to 10% from each tail. Suspected regressions are rerun once with target order reversed and only fail if reproduced. This conservative noise guard is not a statistical confidence interval.
Inconclusive rows do not fail the check. They remain visible for performance review. Bencher retains absolute minimum timings for historical tracking; historical alerts do not gate this PR. Sequential measurements can still be affected by runner drift.
Each install runs 2 more times per revision, untimed, under strace --follow-forks --summary-only. A file syscall regresses when HEAD's fewest calls exceed main's most by more than 2% of main or 50 calls, whichever is larger. mkdir and mkdirat count only the calls that created a directory, since concurrent installs fail a varying number with EEXIST. A syscall whose identical runs differ by more than that tolerance is reported unstable and not gated, unless HEAD's fewest calls also exceed main's most by more than the tolerance plus that difference. Each scenario lists its largest change relative to its tolerance and every row that is not within tolerance.

Regular scenarios report direct and pnpr installs. The peer-heavy resolver scenario compares current Rust, main Rust, and TypeScript pnpm; the linked, injected, and Cargo workspace scenarios compare current Rust against main Rust. Bencher consumes pacquet@HEAD and pnpr@HEAD.
The tables below show mean ± σ. Bencher tracks absolute minimum latency; PR regression checks compare HEAD and main samples from the same runner. Historical timing alerts do not gate PRs.
Scenario: Isolated linker: fresh restore, cold cache + cold store
Scenario: GVS linker: fresh restore, hot cache + hot store
Same install as the isolated fresh-restore hot/hot scenario, into the shared virtual store, the layout pnpm 12 installs into by default. Scenarios run on separate machines, so compare main and branch within each table.
Scenario: Store only: unlocked direct deps, cold cache + hot store
Store-only install (enableModulesDir: false, per-file store index, trusted lockfile) against a lockfile missing the direct dependencies that have peers, with the metadata cache wiped per iteration: the install resolves those from the registry, reuses their subtrees from the lockfile and checks the store, linking nothing. Direct installs only.
Scenario: Cargo: repeat install, hot cache + hot store
Frozen repeat install of a Cargo workspace (cargo.enabled: true) whose crates are already materialized in <storeDir>/v11/crates/ and linked into .pnpm/crates/crates-io. Direct installs only.
❌ Patch coverage is 94.02516% with 19 lines in your changes missing coverage. Please review.
✅ Project coverage is 92.96%. Comparing base (5038f0a) to head (340957f). ⚠️ Report is 9 commits behind head on main.
The Bencher failures on 43dc7f7 are run-to-run noise, not this change:
gvs-fresh-restore-hot-cache-hot-store (pnpr): the first run reported +27.1% (168.46 → 214.11 ms). The rerun did not reproduce it: +12.3% with overlapping samples, which is inconclusive and not gated.
isolated-fresh-install-cold-cache-hot-store (pacquet), readlink calls: the rerun reported +5.2% (main max 15504, HEAD min 16316). In the first run, the same row went the other way, −4.3% (main 16364, HEAD 15653), and was marked unstable because identical runs differed by 747 calls. Across both runs, HEAD's counts fall inside main's own range.
The code path: none of these scenarios sets supportedArchitectures. Without it, store_platform_archives computes the host's platform choice (host detection is cached), finds no listed platform other than the linked one, and returns before walking. It touches the filesystem no further, and the lockfile it gets is a borrow, not a copy.
I've rerun the benchmark once more.

Store supported-platform archives and their dependencies on every install
✨ Enhancement🧪 Tests📝 Documentation🕐 40+ Minutes
AI Description
• Store listed platforms’ archives and transitive dependencies without linking them, including on
warm installs and pnpm fetch.
• Walk each platform’s selected variant snapshots so unrelated archives and dependencies are
excluded.
• Reuse the existing tarball and store-index path, avoiding downloads for archives already stored.

High-Level Assessment
The following are alternative approaches to this PR:
1. Integrate foreign-platform traversal into materialization
➕ Could share some traversal work with the linked-platform install.
➖ Couples store-only packages to linking decisions and complicates warm installs that skip materialization work.
Recommendation: Keep the separate store-only pass. It makes warm installs and pnpm fetch follow the same rule while preserving the boundary between packages linked for this install and archives retained for other platforms. The potential traversal savings of integration do not justify that coupling.

Retain the built lockfile for platform archive selection
• Passes the full built lockfile to on-disk projects while retaining the scoped lockfile for materialization. Also simplifies the calculation of materialized importer IDs without changing its branches.
• Stops fetching other platforms’ variants alongside a newly downloaded linked archive. The pipeline’s store-only pass now handles them for both cold and warm installs.
supported_architectures_link.rsCover cold, warm, fetch, and production store behavior+150/-0
Cover cold, warm, fetch, and production store behavior
• Adds in-process registry tests that isolate install-time store contents from resolver prefetches. They verify foreign archives and dependencies remain unlinked, newly listed platforms work on warm installs, 'fetch' stores them, and production installs exclude a dev dependency.
• Tests that another platform retains its variant and dependency, the linked platform adds nothing, and an unmatched platform retains the 'any' archive without unrelated variant dependencies.
The platform gate was changed to if !optional || self.runs_on_platform(&key, optional), so
required packages are always visited and only optional packages are filtered by platform support.
This matches the suggested fix exactly. A regression test
(a_required_dependency_another_platform_cannot_run_is_kept_with_its_children) was added verifying
that a required win32-only dependency and its child are retained.
Description
PlatformWalk::run applies runs_on_platform to required packages as well as optional ones,
dropping an incompatible required package before visiting its archive or dependencies. When a
foreign variant requires a package whose declared platform does not match the platform being walked,
the store-only pass omits that subtree even though a non-strict install traverses required
incompatible packages.
2. Unlinked dependencies can run scripts✓ Resolved
Git-hosted tarballs are excluded from the store-only archive set (has_own_archive and stored_fetch
check is_git_hosted), so the store-only pass no longer calls tarball_cas_paths for them and their
preparation/lifecycle scripts cannot run for unlinked dependencies.
Description
store_archives sends store-only tarball dependencies through tarball_cas_paths, which runs the
git-hosted preparation path rather than stopping after archive ingestion. When a foreign variant
depends on a git-hosted tarball whose build is allowed, its install and prepublish scripts run
during an install that does not link that dependency.
3. Unneeded optional archives can fail installs✓ Resolved
The walk now calls runs_on_platform(key, optional) before visiting any package; it checks the
package's os/cpu/libc (and, for optional deps, the platform inferred from its name) against the
walked platform and skips non-installable packages entirely, so their archives and subtrees are not
retained. Archives reached only through optional edges are marked optional, and their fetch failures
are routed through swallow_optional_fetch_failure instead of aborting the install
(fetch_kept_archives in platform_archives.rs). Tests in edges.rs cover optional binaries for listed
and unlisted platforms.
Description
PlatformWalk::visit retains a non-variant dependency whenever its snapshot is not materialized,
without checking whether that optional package is installable on the platform being walked. If a
retained parent lists platform-specific optional dependencies, the pass can request archives for
platforms not listed in supportedArchitectures, and a failure in one of those requests aborts the
install rather than being treated as an optional fetch failure.
4. Changeset's first sentence leads with lockfile internals✓ Resolved
The changeset was rewritten. The first sentence now leads with the setting and the user-visible
effect ("pnpm install and pnpm fetch also store, without linking them, the dependencies of the
archives kept for the other listed platforms"). The lockfile-internals phrase "from each variant's
own entry in the lockfile" was removed entirely from the changeset, so the implementation detail no
longer leads the note.
Description
The first sentence of the changeset names the supportedArchitectures setting and the user-visible
effect, but then adds the mechanism "from each variant's own entry in the lockfile" before the
effect. Under the changeset rule, implementation detail belongs in a second sentence, so the release
note's lead reads as internals rather than as the behavior a user will notice.
5. Production installs fetch dev-only peers✓ Resolved
The store-only walk now filters snapshot dependency edges through the install's
PeerSatisfactionEdges (followed_entries), so edges satisfied only by excluded dev-dependency
optional peers are not followed, and a test verifies a production install keeps no archive for such
a peer.
Description
PlatformWalk::follow traverses raw snapshot dependency entries without the peer-satisfaction-edge
exclusions used to construct the materialization closure. When a foreign variant's own snapshot
contains an edge satisfied only by an excluded dev dependency, the store-only pass can fetch that
package and its descendants despite their absence from the production install graph.
6. Failing tests are merged as pre-existing without a quarantine 📘 Rule violation▣ Testability

The PR description reports that 5 of 3054 tests fail and calls them pre-existing because they also
fail on main. Nothing in the diff fixes them or quarantines them with a tracking issue, so the
change would merge with known red tests, which the repository's testing guide forbids ("Never
dismiss a failure as pre-existing"). The new end-to-end tests added here sit in the same suite that
carries those failures, so a reader cannot tell whether the new cases are among the 5 failing ones.

📝 Suggested wording
-With `supportedArchitectures` set, pnpm also fetches into the store the dependencies of the archives it keeps for the other listed platforms, from each variant's own entry in the lockfile, without linking them. Every install and `pnpm fetch` checks for these archives. A platform added to the setting therefore gets its archives and their dependencies on the next install, and a package already installed no longer keeps it from them. An archive the store already holds is not downloaded again.+When `supportedArchitectures` lists other platforms, `pnpm install` and `pnpm fetch` now store the archives of those platforms and the dependencies of those archives. pnpm does not link them. A platform that you add to the setting gets its archives on the next install, including for packages that are already installed. pnpm does not download an archive that the store already holds.

other listed platforms and their dependencies without linking them, including
for already-installed packages, and reuse archives already in the store. Remove
the lockfile-variant claim and end the entry with the relevant issue link.

…only what needs no prep
The store-only walk now leaves out the peer-satisfaction edges the
install leaves out, skips a package a walked platform cannot run, and
keeps whether only optional dependencies reach each archive, so a failed
fetch of one is reported and skipped as the cold path does. It stores no
git repository or git-hosted tarball, whose preparation can run scripts.

A non-strict install keeps such a package and only warns, so only an
optional one is left out of the store-only walk.

Name the reachability value at the function boundaries.
PlatformWalk::queue and root_dependencies expose an unnamed (PackageKey, bool). Replace that tuple with a small struct such as Dependency { key: PackageKey, optional: bool }. Keep KeptArchive.optional and the named optional parameters as predicate bools. Do not introduce Reach or a merge method solely for this style rule.
Adapt root_dependencies and queue.push_back to construct Dependency, and destructure it when popping the queue.

Pass only the keys the host materializes to the store-only walk.
On a frozen install, materialization_closure runs with an empty skip set. It keeps a snapshot that the host skips for installability. downloads.rs:119 then passes inputs.wanted.snapshots as materialized. The walk treats any key in that map as already stored. For a Linux-only optional registry package on a Darwin host, store_platform_archives therefore does not keep its Linux archive. The cold path also does not fetch it, because snapshot_plan.rs drops installability-skipped snapshots. The Linux archive stays absent from the store, so a later Linux install cannot take it from the store offline.
The walk should test membership against the keys this install materializes, not the full wanted snapshot map.

Summary
This is the last part of
supportedArchitecturesfor platform variants (pnpm/rfcs#69, "Install"). Every install, andpnpm fetch, now stores the archives the listed platforms keep together with the packages those archives depend on. Nothing extra is linked.supportedArchitecturesis picked up by the next install, including one that reuses every slot.pnpm fetchruns the same frozen install pipeline, so it follows the same rule.current_lockfile::platform_archives). For each listed platform, it starts at the installed projects. For a package with variants, it keeps every archive that platform fetches (VariationsResolution::fetched_for, the same selection the fetch rule uses). It then follows each kept archive's dependencies, from the variant's own<name>@<version>/variants/<tag>snapshot when there is one, and otherwise from the version's. So a package reachable only through an archive no listed platform keeps is never fetched. Archives and packages the install already links are skipped.InstallPackageBySnapshot::store_archives). It downloads the kept archives concurrently, bounded by the client's per-host limit, through the existing tarball path. An archive the store already holds is read from the store index, not downloaded again.supportedArchitectures, or when it lists only the platform the install links for ([current]), the pass returns before walking.SnapshotSelectiongainsplatform_lockfile, the whole wanted lockfile with every variant's own snapshot, because the materialized closure has those snapshots wired to the linked platform.Test plan
