install: pnpm parity — dedupe, prune, pm licenses, audit fix, add --filter/--catalog, nested overrides, transitive update, and workspace fixes

[Jarred-Sumner]

Brings Bun's package manager to parity with pnpm for monorepo workflows, and fixes the bugs found while checking every command against pnpm's implementation, pnpm's test suites, pnpm's open issue tracker, pnpm's docs, npm's arborist fixtures, and — for bun update — running real pnpm and Bun side by side on the same projects.

What does this PR do?

New commands

• bun dedupe [--check] — collapses duplicate versions in bun.lock onto the smallest set that still satisfies every dependent's range, using only versions already in the lockfile, then installs. Never downgrades a direct dependency unless that is the only way to drop a version; keeps patched versions (and anything needed to reach them, and says so); refuses to run on a lockfile that is behind package.json. --check exits 1 without writing.
• bun prune [--production | --omit=…] [--dry-run] [--filter <ws>] — removes everything in node_modules that the lockfile does not put there; --production leaves exactly what bun install --production would. Hoisted and isolated layouts, Windows junctions and shims, workspace links, bundled deps; refuses when package.json and bun.lock disagree or when node_modules was laid out by a different linker; understands turbo-pruned checkouts.
• bun pm licenses [--json] [--prod|--dev] [--long] [--filter <ws>] — installed packages grouped by license, with a (dev) marker and paths/license/description in --json.
• bun audit fix [--latest] [--dry-run] [--json] — moves each vulnerable package to the lowest safe version its dependents accept, per installed instance; rewrites exact pins when that is the only way; --latest also rewrites your own declared ranges (root, workspace, catalog) so a semver-major fix can be taken, and every blocked or unfixable item is followed by the command that resolves it (bun audit fix --latest, bun audit --ignore GHSA-…); re-audits the tree it actually installed and reports/exits from that second response (npm's _submitQuickAudit), so an advisory that starts at the version it moved to is not missed; works across registries; security fixes bypass minimumReleaseAge with an annotation. bun audit --json honors --audit-level/--ignore for its exit code; --omit is honored by audit and licenses.

bun update semantics (pnpm's model)

• A bare bun update re-resolves transitive packages too — every edge moves to the newest version its own range (or dist-tag) allows, per dependent, so bun.lock no longer stays stale after an update; overrides/catalogs changed since the last install are honored. From a workspace member or --filter, only what the selected workspaces reach is re-resolved; from the root, everything.
• bun update <name> reaches any depth, matches npm: aliases by real name, updates in place, never adds to package.json, and errors on a name nothing selected depends on. -r/--filter fan a named update out across workspaces. --latest never downgrades a locked version that is ahead of the tag, and update <name> --latest also refreshes that package's own dependencies.
• Plain updates keep dist-tag literals and non-caret ranges (*, 1.x, ^1 || ^2) exactly as written and only move the lockfile; --latest rewrites them to the resolved version as before. bun update -i applies only what you selected. New: positional patterns (bun update '@types/*'), --dev/--prod/--no-optional, -L, bun up.
• package.json is written after resolution and bun.lock's declared ranges, overrides and catalogs are re-derived from the final package.json, replacing the per-command literal rewriting; a no-op update leaves the file byte-identical.

Overrides

• Nested overrides (Support nested "resolutions" / "overrides" #6608): npm's nested objects, yarn's a/b paths and pnpm's a>b selectors, applied to the direct parent→child edge; version-scoped targets ("lodash@<4.17.21": "4.17.21", the shape pnpm audit --fix writes), matched against the dependent's declared range as pnpm does. Rules persist inside the overrides section and the file is stamped lockfileVersion: 3 only when such rules exist — existing lockfiles are byte-identical. Flat overrides additionally fix $ref to workspace-member deps, catalog-valued rules going stale, and warn on pnpm's - / pkg@ forms.

Workspaces and filters

• bun add|remove|update … --filter <ws> (also -F, also bun install <pkg> --filter) edits the selected workspaces' package.json files and links only those workspaces, like bun install --filter. Filters gain pnpm's relation selectors (foo..., ...foo, foo^..., ...^foo) and {dir} subtrees, for the install family and bun run --filter; --filter may precede the subcommand; every command warns about patterns that match nothing; add/remove no longer select the root implicitly.
• bun add <pkg> --catalog[=name] reuses an existing catalog entry, keeps a range an explicit version fits, catalogs the range a package already declares, decides per target, and refuses workspace names and local paths; a plain bun add uses a default-catalog entry when one exists. A package defined in both catalog and catalogs.default is an error. catalog: peers of registry packages bind to the importer's copy instead of the root catalog.
• --frozen-lockfile / bun ci on turbo-pruned monorepos: pruned-away workspaces are tolerated, a survivor depending on a pruned workspace is an error, catalog subsets are accepted, and an overrides/catalogs change is a frozen failure.

One output vocabulary

Every command here prints the install family's shapes: header, glyph rows (+/-/↑, dedupe's ↳ name old → new), exactly one noun-first summary line with counts and a duration (2 duplicate versions removed, 3 packages installed (checked 5 packages) [12ms], N packages removed (checked C) [t]), no-ops that say what was checked, remedies printed as copy-pasteable command lines, warnings as warn:, --silent printing nothing, and errors with their remedy together on stderr. Transitive and named updates render as the summary's ↑ rows (once per package; --dry-run prints the same rows plus N packages would be updated); dedupe reports after the install it triggers, so lifecycle-script output never splits it. A lockfile whose bytes did not change is no longer rewritten (Saved lockfile only prints on a real write; --lockfile-only no-ops print Done! Checked N packages (no changes)). This came out of running every command against fixtures and comparing with install/add/remove (95 findings, all fixed).

Config precedence

A project's bunfig.toml now beats any .npmrc (project or user-level) for the same key (npmrc files → bunfig's set fields → CLI); npmrc-only settings such as //host/:_authToken still attach to bunfig-declared registries, matched by host and path regardless of how either file spells the trailing slash.

Lockfile migration

• package-lock.json: rebuilt around a reachability walk that derives each resolution from the entry itself. Fixes git+https://github.com/… resolutions being written unparseably (the next install threw the lockfile away), root bundleDependencies migrating to an empty lockfile, lockfileVersion 1 (and npm's upcoming 4) making bun install exit 1 instead of resolving fresh, dependency-level bundles, dependencies+optionalDependencies double edges, unreferenced entries aborting the migration, duplicate packages for identical name@version at nested paths, lost optionalPeers, lost integrity when a bundled copy was seen first, and overrides not being carried over. All 57 of arborist's v2/v3 fixture projects are vendored and migrated under snapshot.
• pnpm-lock.yaml v9: bare-hash patchedDependencies, snapshot aliases, catalog:default, recorded tarball URLs, git path:, multi-document files, runtime: entries, named registries, peer-suffixed keys chosen per importer, injected workspaces, manifest-only importer deps.

Isolated linker

• An existing store entry whose dependencies re-resolved (override, dedupe, update) now has its links refreshed on the next install (measured cost below). bun prune builds the same store the installer builds, so stale name@version+<peerhash> variants left by peer bumps are removed and a kept package's real entry never is (whether it was installed with full or --production features); on the hoisted linker, dedupe / audit fix / update delete the nested copies whose rows they collapsed instead of leaving the old copy loadable.
• Blocked entries resume through per-entry intrusive waiter lists instead of a scan of every store entry after each completion (robobun's fix(install): optimize isolated linker to avoid O(N²) complexity in resumeUnblockedTasks #25983/fix(install): optimize isolated linker to avoid O(N²) complexity in resumeUnblockedTasks #28425 attempted this). Measured on the reporter's repro from Significant Performance Issue on Dependency Installation With no New Packages (70x slower than pnpm) #25799 (2,259 store entries) and a synthetic 6,425-entry monorepo, PR build vs merge-base build: main-thread CPU in the link phase drops 0.85 → 0.33 s and 5.5 → 0.85 s (the removed work grows quadratically); wall time is unchanged with spare cores and 16% / 26% faster pinned to one CPU, the CI/Docker shape in those reports. (The minute-long installs originally reported were peer resolution, fixed before this PR's base.)
• Two pre-existing leaks surfaced by the new LSan-enabled tests are fixed: the header buffer of every authenticated registry request, and the per-entry lifecycle-script lists.

Other bug fixes

bun add x@npm:pkg writes a range; bun add --trust a b no longer drops b when a was already trusted; bun add x --dev no longer rewrote every group in bun.lock; catalog: peer hoisting; dependency::Version::eql treated all catalog: specifiers as equal; a file: package whose dependencies reach itself (its own name, an npm: alias under its own name, two link targets depending on each other — the shapes a package-lock.json migration produces, and #25202's workspace:. self-reference) hung bun install forever in the hoisting tree — the migration shapes now install, and #25202's literal shape now terminates with Workspace dependency "foo" not found rather than installing as npm does; a peer of a file: package that was only placed nested was also written to optionalPeers in a migrated bun.lock, so the next --frozen-lockfile failed and a plain install rewrote the lockfile; catalog: literals in bun update; alias output in the install summary; help/completions for everything above.

Behavior changes to note in the release notes

• bun update moves transitive packages; bun update <name> no longer adds an undeclared package (exit 1); --production/--prod on update means "only update dependencies and optionalDependencies" (a group filter like --dev, not the install flag) and -r+names with no match is an error; -i updates only the selection.
• Project bunfig.toml overrides any .npmrc.
• bun install <pkg> --filter x edits x (not the root); bun add y --filter x no longer installs a package named x; add/remove --filter '*' no longer includes the root.
• A plain bun add x in a workspace whose default catalog lists x writes catalog:; audit fix may rewrite exact pins; --frozen-lockfile --lockfile-only writes nothing; overrides/catalog changes fail frozen installs.
• One-time lockfile churn after upgrading for projects with catalog: peers or dead pkg@range override rows; lockfiles that use nested/scoped overrides are v3 and unreadable by older Bun (only when opted in). Turborepo, Nx and Dependabot have been checked; the needed upstream changes are open (fix(core): accept bun.lock lockfileVersion 2 and 3 nrwl/nx#36666 covers v2 and v3; fix(bun): Preserve overrides objects, trustedDependencies, workspace bins and git integrity through prune; accept lockfileVersion 3 vercel/turborepo#13740 accepts v3 and preserves the object rows through prune — turborepo main today parses v2 and rejects v3; dependabot needs nothing). Note v2 itself only exists on the 1.4 line.
• bun audit --json keeps npm's contract: --audit-level/--ignore decide the exit code, the JSON document is the full registry report (closes audit: apply --audit-level and --ignore filters to --json output #31013 as won't-change). Automatic removal of stale node_modules entries on plain bun install (install: remove node_modules entries that left the lockfile #32974) is separate from this PR: bun prune is the manual form, and dedupe / audit fix / update now clean up the nested copies they collapse on the hoisted linker; install: remove node_modules entries that left the lockfile #32974 should reuse prune's planner, and Add bun pm sbom command #29512 (sbom) is sequenced after this so it can build on reachable.rs instead of carrying its own walk.
• Deliberately kept where we differ from pnpm: root bun update covers the whole workspace; dependents whose ranges allow follow a moved version (one copy, not two); --latest works on transitive names; --no-save touches neither file; prune deletion failures exit 1; audit requests stay per-registry.

Performance

Measured on a 1,113-package Next/Prisma/MUI app (PR build vs a PR build of the merge base, interleaved, plus canary and 1.3.14): every hoisted cell is within noise except no-op install, +0.8 ms (+2%, identical syscalls); isolated no-op is +1.9 ms (+3.9%) — the deliberate cost of re-checking existing entries' links every install rather than persisting a stamp file. Everything added is otherwise off the plain-install path (gated on the feature being used or on a diff), and id-indexed sets are bitsets.

How did you verify your code works?

~1,100 new or ported test cases across the install suites (designed behavior, cases ported from pnpm's suites, pinning tests for pnpm bugs this implementation is immune to, arborist's fixtures, and the CI review findings), all toStrictEqual; the whole test/cli/install directory passes locally and the existing suites are unchanged except where a pre-existing expectation was deliberately changed (each listed above). bun update was additionally verified with a rerunnable differential harness that runs pnpm 11 and this branch on 26 scenario families against one registry and diffs the resulting resolutions edge by edge — after this PR only the deliberate differences above remain. Ecosystem: Turborepo, Nx and Dependabot were checked against the new lockfile output.

Co-authored work absorbed with credit: @kjanat's #38190 (alias handling, co-author on the commit), @charpeni's #31143 and @crystalin's #34407 (both superseded), and the tests of the earlier bun update PRs (#31752 by @zlotnika, #33127, #36381, #36729, #38224). robobun's #34688 (folder-dependency cycles; its tests are lifted, co-author on the commit) and #37289 (migrated optionalPeers; its test is lifted, co-author on the commit) were fixed independently here and are closed by this PR. #28422's quadratic scan is fixed here as well (already closed).

Related but not closed — bun prune gives these a manual fix while the automatic-cleanup asks stay open: #8662, #26305, #29793, #21216, #16176. Also related: #10930, #26970, #26751.

Inline comments:
In `@docs/pm/cli/add.mdx`:
- Line 139: Correct the filtered-workspace documentation to remove the claim
that package.json files are written when the lockfile is saved; state that
pending manifest edits are flushed only after install_with_manager succeeds, so
they may remain unwritten when installation or a lifecycle script fails.

In `@src/install/dedupe.rs`:
- Around line 360-373: Replace Global::crash() in the LoadResult::Err handling
with Global::exit(1), matching the existing prune behavior for user-reachable
lockfile load failures while preserving the current error reporting and log
printing.
- Line 233: Update the initialization of cur in the deduplication flow to avoid
implicitly cloning the dereferenced resolutions buffer via to_vec; clone
lockfile.buffers.resolutions directly or explicitly convert it with as_slice()
before to_vec, preserving the resulting Vec<PackageID>.

In `@src/install/lockfile/Package/WorkspaceMap.rs`:
- Around line 243-245: In the skip_missing/ENOENT branch of WorkspaceMap’s
workspace lookup, emit an equivalent verbose message identifying the skipped
workspace path before continuing. Match the existing skipped-workspace reporting
used by the Package.rs diff-side logic, while preserving the current continue
behavior.

In `@src/install/lockfile/pruned_workspaces.rs`:
- Around line 13-17: Handle failures from both append calls when building
package_json_path; if either append fails, return false so the workspace is
treated as present and retained. Only call bun_sys::exists_z after both appends
succeed, preserving its existing result.

In `@src/install/PackageManager/add_remove_with_filter.rs`:
- Around line 503-508: Fix both Clippy findings in the update flow: replace the
assignment to manager.trusted_deps_to_add_to_package_json in the loop with
clone_from using trusted_snapshot, and change the Option fallback around
changed.first() near the find call from or to or_else so the fallback is
evaluated lazily.

In `@src/install/PackageManager/install_with_manager.rs`:
- Around line 1774-1780: The frozen-lockfile early-return path around
loaded_from_binary_lockfile and migrating_to_text needs regression coverage for
the migration exception. Add a test that creates bun.lockb, runs bun install
with --frozen-lockfile, --lockfile-only, and --save-text-lockfile, then verifies
bun.lock is written and bun.lockb is removed.

In `@src/install/PackageManager/PackageJSONEditor.rs`:
- Around line 777-801: In
src/install/PackageManager/PackageJSONEditor.rs:777-801, update
rewrite_lockfile_catalogs to assert that catalogs.find_mut and dependency::parse
both succeed; in src/install/PackageManager/add_catalog.rs:360-378, add the same
guards to rewrite_lockfile_entries. Extract the shared append-and-reparse loop
into one helper used by both call sites, preserving the existing version
assignment and clamping behavior.

In `@src/install/pnpm.rs`:
- Around line 239-250: Update the Git resolution construction in the migration
branch identified by `Resolution::init` and `Repository` so the parsed commit is
assigned to both the existing `committish` field and `Repository::resolved`.
Preserve the current repository normalization and default handling for missing
commits.

In `@src/install/prune.rs`:
- Around line 709-721: Add a short comment in the EntryKind::SymLink branch
explaining that symlinks targeting removed store entries remain in this plan
because housekeeping::unlink_links removes them later, preserving removal-count
and layout_mismatch handling. Keep the existing matching logic unchanged and
make the comment clarify the ownership split between this code and unlink_links.
- Around line 128-134: Replace the explicit drop(load) in the
load_lockfile_from_cwd result handling with a narrower scope that contains load,
loaded, and their borrow usage, allowing the borrow to end naturally while
preserving the existing loaded match behavior.
- Around line 172-185: Extract the node-linker-to-Layout resolution currently in
the prune flow into a shared helper, including the migrated_from_npm() case so
Auto with workspaces matches the installer’s Hoisted selection. Update prune and
the installer to reuse this helper, preserving the existing explicit
Hoisted/Isolated and config-version behavior.

In `@src/runtime/cli/audit_command.rs`:
- Around line 101-108: Ensure bun audit fix honors the captured production/omit
configuration instead of unconditionally auditing all dependencies: thread the
relevant flag from exec through audit_fix to collect_packages_for_audit, or
explicitly reject these flags like --json. Preserve the existing fix flow while
preventing dev-only dependencies from being planned and pinned when
production-only auditing is requested.
- Around line 266-277: Update the audit-fix installation flow around
install_with_manager and save_lockfile so audit-fix pins are not persisted when
installation fails. Check install_summary.fail before saving the lockfile, or
defer the save until the installation succeeds, while preserving the existing
error handling and successful-install behavior.

In `@src/runtime/cli/dedupe_command.rs`:
- Around line 28-31: Update the MissingPackageJSON branch in the dedupe command
to include the resolved working directory in the error and add the concrete “bun
init” remedy, matching the existing message convention used by audit_command.rs
and package_manager_command.rs.

In `@src/runtime/cli/pm_licenses_command.rs`:
- Around line 301-323: Update read_package_info to handle parse diagnostics
through the provided log: surface the accumulated errors before the command’s
output and/or reset the log after processing each manifest, ensuring malformed
package.json details are not silently discarded and diagnostics cannot grow
across DiskIndex::scan_node_modules.

In `@test/cli/install/bun-add-filter.test.ts`:
- Around line 710-714: Reuse the existing lockfileJson helper for parsing
bun.lock in this test instead of duplicating JSON.parse and trailing-comma
cleanup; move its declaration above the test if needed, and update the local
lockfile assignment to call it.

In `@test/cli/install/bun-audit-fix.test.ts`:
- Around line 850-854: Update the setup install assertions in the affected test
cases to assert the complete result from run, including stderr (and stdout as
appropriate), rather than only exitCode. Apply this consistently to the install
calls around the current assertion and the matching cases near the later
referenced assertions, preserving the expected successful exit status while
exposing diagnostics on failure.

In `@test/cli/install/bun-pm-licenses.test.ts`:
- Around line 103-109: Update the licensesJson helper to assert exitCode is 0
immediately after validating stderr and before calling JSON.parse(stdout), so
command failures report the exit-code assertion instead of a parsing error.
- Around line 64-76: Drain every piped subprocess stream concurrently with
process completion to prevent test hangs. In
test/cli/install/bun-pm-licenses.test.ts lines 64-76, read proc.stdout in the
install helper or set it to ignore; lines 430-434, read proc.stdout with
proc.stderr and proc.exited; lines 437-446, read and assert proc.stderr
alongside proc.stdout and proc.exited; lines 521-536, reuse install; and lines
651-658, read proc.stderr alongside proc.stdout and proc.exited.

Apply the same fix in `@test/cli/install/bun-prune.test.ts` around lines 272 -
283: The prune test leaves stdout piped and unread.

Apply the same fix in `@test/cli/install/migration/pnpm-lock-v9.test.ts` around
lines 519 - 528: Both migration install subprocesses leave stdout piped and
unread.

In `@test/cli/install/catalog-peer-hoist.test.ts`:
- Around line 10-12: Update the beforeAll setup to start the registry with
registry.start().catch(() => {}) without awaiting its readiness, then wait
solely for readiness using await waitForPort(registry.port, 30_000).

In `@test/cli/install/catalogs.test.ts`:
- Line 198: The test around runBunInstall must make the savesLockfile: false
behavior observable by modifying the package manifest before installation, then
verify the new dependency state is installed while bun.lock remains
byte-for-byte unchanged. Update the relevant test setup and assertions without
altering unrelated install behavior.

In `@test/cli/install/migration/pnpm/v9-reference-shapes/package.json`:
- Line 8: Add the missing tb-1.0.0.tgz fixture referenced by the tb dependency
in package.json, ensuring the committed pnpm-lock.yaml fixture can resolve the
local package during tests.

Assert the exit code before parsing stdout.

JSON.parse(stdout) runs before the exit-code assertion. If the command fails with empty stdout and empty stderr, the test reports SyntaxError: Unexpected end of JSON input instead of the real exit code. Move the exit-code assertion before the parse.

♻️ Proposed refactor

   const [stdout, stderr, exitCode] = await licenses(dir, ...args, "--json");
   expect(stderr).toBe("");
+  expect({ stdout, exitCode }).toMatchObject({ exitCode: 0 });

Found 12 issues this PR may fix:

1. .npmrc config overrides .bunfig.toml #20593 - Config loading is reordered to npmrc → bunfig → CLI (overlay_bunfig_install), so bunfig.toml settings are no longer clobbered by ~/.npmrc while npmrc _authToken entries still attach.
2. bun install: pnpm lockfile migration ignores tarball URL from resolution, breaks GitHub Packages #28959 - pnpm-lock v9 migration now preserves resolution.tarball instead of reconstructing an npm-style URL, which is what broke GitHub Packages.
3. bun install --frozen-lockfile --filter fails in Docker when bun.lock was generated from the full workspace but only a subset of workspace manifests is present #28402 - --frozen-lockfile now skips workspaces listed in bun.lock whose package.json is missing on disk, which is the Docker/turbo-prune subset case reported here.
4. bun remove and bun remove --filter 'pkg-*' not works #27897 - Adds --filter/-F to bun add and bun remove, so bun remove --filter 'es6tween-*' uglify-js no longer fails with "unrecognised dependency format".
5. [BUG] Bun audit --prod won't work in monorepos #26675 - bun audit --prod now computes the production package set per level instead of only checking the root's direct deps, so workspace devDependencies stop being reported.
6. bun install --production enforce more settings than the docs state #10949 - Adds the bun prune --production the reporter asked for: strips devDependencies from node_modules without reinstalling.
7. Completely removing dev dependencies #18504 - bun prune --production / --omit=dev removes dev-only packages already on disk, so a build stage can install everything and ship without devDependencies.
8. Bun doesn't remove hardlinks when using linker = isolated #21216 - bun prune handles the isolated layout: it deletes unused node_modules/.bun store entries and their links, reclaiming stale hardlinks left after bun update.
9. bun remove doesn't remove the package from node_modules when using isolated linker #26305 - After bun remove under the isolated linker, bun prune removes the package that is no longer in bun.lock from node_modules/.bun.
10. Running bun install does not delete extraneous dependencies #16176 - bun prune deletes packages present in node_modules but not placed by bun.lock — exactly the extraneous transitive deps left behind after an upgrade.
11. bun remove <package> should remove the dependencies that the package depended on if they are no longer used #8662 - bun prune after bun remove deletes the now-orphaned transitive deps and their dangling .bin shims.
12. bun update --linker hoisted leaves stale workspace-local dependency that shadows updated root install #29793 - bun prune walks every node_modules the hoisted tree installs into, including workspace-local ones, so a stale nested copy shadowing the updated root install is removed.

[kjanat]

@Jarred-Sumner Heads up before the planned #13388 follow-up here: #38190 fixes #11901 for the separate bun add npm-alias path, preserving the alias through resolution and consistently writing the resulting specifier to both package.json and bun.lock. It covers bare aliases and dist-tags as well as explicit exact versions and ranges, scoped/unscoped targets, and the install output.

It currently touches some of the same PackageJSONEditor / lockfile machinery that the structural bun update fix will likely change, while the request-side alias-resolution behavior itself is orthogonal.

Would it make sense to land #38190 first, then build the #13388 work on top of it? That may avoid having to reintroduce/reconcile the bun add alias handling afterward. Happy for it to go the other way if the new lockfile shape makes the rebase cleaner.

Additional findings (outside current diff — PR may have been updated during review):

• 🟡 src/runtime/cli/audit_command.rs:72-76 — bun audit <anything-but-fix> silently runs a plain bun audit: line 72 sets fix = positionals[1] == b"fix", and the extra-positional check on line 73 is gated on fix, so a typo like bun audit fixx or bun audit foo is never rejected — it just runs report-only mode with no diagnostic. bun dedupe and bun prune (both new in this PR) reject unexpected positionals with an explicit error, and the docs added here call out that bun audit --fix is rejected as an unknown flag, so this is the missed sibling case. Consider adding else if cli.positionals.len() > 1 { Output::err_generic("bun audit: unrecognised subcommand \"{}\" (did you mean \"fix\"?)", ...); Global::exit(1); }.

  Extended reasoning...

  What the bug is

  At src/runtime/cli/audit_command.rs:72-76, the new fix subcommand is detected as:

  let fix = cli.positionals.len() > 1 && cli.positionals[1] == b"fix";
  if fix && cli.positionals.len() > 2 {
      Output::err_generic("bun audit fix does not take arguments", ());
      Global::exit(1);
  }

  When positionals[1] is anything other than exactly b"fix", fix stays false and the len() > 2 check is skipped (it's gated on fix). Execution falls through to Self::audit(...) — a plain report-only bun audit. The extra positional is never rejected and no diagnostic is printed.

  Step-by-step proof

  Command: bun audit fixx (one-character typo of fix).

  1. CommandLineArguments::parse(Subcommand::Audit) returns cli.positionals = [b"audit", b"fixx"].
  2. Line 72: positionals.len() > 1 is true, positionals[1] == b"fix" is false → fix = false.
  3. Line 73: fix && ... short-circuits to false → the error branch is skipped.
  4. PackageManager::init runs normally.
  5. Since fix == false, the if fix { audit_fix::... } branch is not taken; Self::audit(...) runs a plain report.
  6. Output banner reads bun audit v... (not bun audit fix v...), no fixing: section is printed, and the exit code follows bun audit semantics (0 if no vulnerabilities remain after filters). Nothing tells the user their positional was ignored.

  The same trace holds for bun audit foo, bun audit fx, bun audit Fix, etc.

  Why existing code doesn't prevent it

  The only positional validation in this function is at line 73, and it is conditioned on fix == true. There is no else branch and no earlier check on positionals[1]. CommandLineArguments::parse accepts arbitrary positionals for Subcommand::Audit (declared as <POS> ... in AUDIT_PARAMS_FULL) and does not validate them.

  Why this belongs in this PR ("fix the whole class")

  Per REVIEW.md: "Fix the whole class in the same PR … parallel switch arms, sync/async twins … copy-pasted blocks." This PR introduces the fix subcommand and adds the partial check on lines 73–76 (bun audit fix xyz → error), showing awareness that positionals should be validated. The two sibling commands added in the same PR both reject unexpected positionals:

  • dedupe_command.rs:16: if cli.positionals.len() > 1 { Output::err_generic("bun dedupe does not take arguments..."); ... }
  • prune_command.rs:13: if cli.positionals.len() > 1 { Output::err_generic("bun prune does not take arguments..."); ... }

  And the docs this PR adds to docs/pm/cli/audit.mdx explicitly note: "fix is a subcommand, not a flag: bun audit --fix is rejected as an unknown flag." — the author already considered the typo surface for the flag spelling but not the positional spelling. The positionals[1] != b"fix" case is the missed sibling.

  Pre-PR, bun audit had no subcommands and already ignored extra positionals, so this was harmless before. This PR creates the surface where a one-character typo silently runs the wrong operation (report-only instead of applying fixes) with different exit-code semantics.

  Impact

  Low. An interactive user will almost certainly notice: the banner says bun audit not bun audit fix, there is no fixing: / blocked by a dependent's range: section, and the trailing hint block prints To upgrade only the vulnerable packages ... bun audit fix. Only in a CI pipeline that checks the exit code alone (and where bun audit and bun audit fix would exit differently) could the mistake go unnoticed — and that requires a scripted typo, which is rare. Nothing crashes, no data is corrupted, and the plain-audit output is still correct for what it is.

  Fix

  Add an else branch after line 76:

  let fix = cli.positionals.len() > 1 && cli.positionals[1] == b"fix";
  if fix && cli.positionals.len() > 2 {
      Output::err_generic("bun audit fix does not take arguments", ());
      Global::exit(1);
  } else if cli.positionals.len() > 1 && !fix {
      Output::err_generic(
          "bun audit: unrecognised subcommand \"{}\" (did you mean \"fix\"?)",
          (BStr::new(cli.positionals[1]),),
      );
      Global::exit(1);
  }

  This matches the pattern in dedupe_command.rs / prune_command.rs and REVIEW.md's "Error messages … name what failed and why … the rejected value echoed back … a concrete remedy".

• 🟡 src/runtime/cli/audit_command.rs:199-206 — When collect_vulnerabilities() returns None (registry response isn't valid JSON — e.g. an HTML proxy/captive-portal page), audit_fix writes the raw body to Output::writer() (stdout) and exits 1 with no error: line, whereas the sibling audit --json path at lines 151–158 handles the identical condition via pretty_errorln!("<red>error<r>: audit request failed to parse json. Is the registry down?") on stderr. Print the same (or similar) error to stderr here — per REVIEW.md, error messages go to stderr and name what failed; this also breaks the --json contract that stdout is one JSON object.

  Extended reasoning...

  What the bug is

  bun audit fix handles an unparseable registry response differently from bun audit --json, and in a way that violates REVIEW.md's error-message rules. When the audit endpoint returns a 2xx body that is not valid JSON (or is JSON whose root is not an object), collect_vulnerabilities() returns Ok(None). The new audit_fix path at audit_command.rs:212-217 then does:

  None => {
      let _ = Output::writer().write_all(&response_text);
      let _ = Output::writer().write_all(b"\n");
      Output::flush();
      Global::exit(1);
  }

  Output::writer() is the stdout stream (see bun_core/output.rs, Source::stream), so the raw response — typically an HTML error page from a corporate proxy or captive portal — is dumped to stdout with no error: line, and the process exits 1.

  The sibling path already does it correctly

  The identical None case in audit() for the --json flag, at lines 151–158 of the same file, prints the raw body to stdout (which is expected there — --json documents that stdout is the raw response) and an error: line to stderr:

  None => {
      bun_core::pretty_errorln!(
          "<red>error<r>: audit request failed to parse json. Is the registry down?"
      );
      Ok(1)
  }

  REVIEW.md, under Error handling → "Error messages are reviewed word-for-word as code", requires "Name what failed and why … stderr not stdout", and under Correctness → "Fix the whole class in the same PR" asks that sibling sites share the same handling.

  Step-by-step proof

  1. User is behind a captive portal / corporate proxy that returns 200 OK with an HTML body for POST /-/npm/v1/security/advisories/bulk.
  2. bun audit fix (no --json): line 190 prints the version banner to stderr; send_audit_requests returns the HTML in response_text; collect_vulnerabilities calls the JSON parser at ~line 881, which fails → returns Ok(None).
  3. Line 213–214 write the HTML to stdout; line 216 exits 1.
  4. The user's terminal shows the banner on stderr, then a wall of <html>… on stdout, then a nonzero exit — with nothing that says "audit request", "registry", or "failed to parse".
  5. bun audit fix --json is worse: this PR's docs (docs/pm/cli/audit.mdx) say "--json prints one JSON object", but stdout here is arbitrary bytes, so anything piping it to jq breaks with a parse error and no diagnostic on stderr to explain why.

  Why existing code doesn't prevent it

  send_audit_requests only fails on a non-2xx status or a transport error (which take the documented "audit request failed" path). A 2xx with a non-JSON body — which captive portals and misconfigured proxies commonly produce — reaches collect_vulnerabilities and hits this arm. Nothing else in audit_fix inspects response_text before this point.

  Impact

  Minor. The exit code is correctly 1 (so CI still fails), the raw body on stdout gives some diagnostic if the user reads it, and the trigger is narrow (2xx-with-non-JSON from the advisory endpoint). But the user has to guess why the command failed, the --json contract is violated, and it's inconsistent with the sibling handling this PR left in place ~60 lines above.

  Fix

  Mirror the sibling path — print the same error: line to stderr (and, at least for the non---json case, drop the raw body from stdout or move it to stderr):

  None => {
      bun_core::pretty_errorln!(
          "<red>error<r>: audit request failed to parse json. Is the registry down?"
      );
      Output::flush();
      Global::exit(1);
  }

I think we can keep it at v2 because we haven't shipped v2 in a prod release

[Jarred-Sumner]

Turborepo shipped v2 support, so I'm not sure

[alii]

Went through this against 4dd537b (the resolver and audit fix scanner changes in 9161c92 already took care of two things I had queued up, so those are dropped). Threads are per finding so they can be resolved one at a time.

The ones I'd want before this merges: audit fix reporting/exiting from the advisories fetched for the old versions (audit_command.rs:275), the npmrc token getting dropped when bunfig spells the registry differently, which is a 401 regression on the #20593 shape this PR closes (PackageManager.rs:1386), the named in-place update installing without scanning (install_with_manager.rs:674), prune keeping every old peer-hash variant under isolated (prune.rs:1148), and the v3 stamp bypassing the v1 walk (bun.lock.rs:216, also the one concrete input to Dylan's v2/v3 question: v2 is only on the 1.4 line, not in 1.3.14, but turborepo main already parses v2 and rejects 3). The hoisted thread on install_with_manager.rs:273 is a call to make rather than a bug: dedupe/audit fix/update on hoisted leave the collapsed nested copy on disk and the docs say otherwise. The rest are consider/nit.

Things I checked that held up and are not threads: dedupe onto a patched older version, the name@range selector semantics vs npm/pnpm, the direct-edge meaning of nested rules (documented), the plain bun add catalog: change and its flag interactions, the lockb trailer, the waiter list rewrite, the relink cost, the frozen-lockfile pruned tolerance, and bunfig beating a project .npmrc (intended per #20593, though the body says ~/.npmrc and it is any .npmrc, worth fixing in the notes). Two loose ends outside the diff: #31013 is open with a different answer for audit --json + --audit-level (it filters the output, this PR only fixes the exit code, which is what npm does) so it should probably be closed by this, and #32974 (auto prune on install) is the automatic version of what bun prune does by hand, so it is worth saying which way that is going.

I have one more pass finishing on -g and bun.lockb handling across the new commands and on which pieces are separable; will add those as they land.

should fix: audit fix reports and exits from the advisories it fetched for the old versions.

The bulk request goes out once with the versions currently in bun.lock (:215), we install, and then finish_installed rescans the new lockfile against that same response (audit_fix.rs:943-1008; a name missing from by_name is skipped at :971). The bulk endpoint only returns advisories covering the versions you sent, which is also how the test mock behaves (bun-audit.test.ts:135-143). So anything that only affects the version we move to, and anything the new version pulls in, is invisible to the Fixed/remaining lines and to the exit code, and the next plain bun audit contradicts them. Lowest-safe targeting (audit_fix.rs:539-547, :609-641) makes this the common case rather than a corner: we land on the first release past the ranges we know about, which is exactly where an advisory that starts after the installed version begins. The scanner hookup in the last commit only covers people who configured one.

Repro with the existing mock: no-deps@1.0.0 installed with range >=1.0.0, filtering registry with adv1 <1.0.1 and adv2 >=1.0.1 <2.0.0. Only adv1 comes back, we install 1.0.1, print Fixed 1 with nothing remaining and exit 0, and bun audit afterwards exits 1. The disjoint-ranges test at :1689 is this scenario minus the failure (adv2 never reaches bun there either), and the two "introduced by the fix" tests at :2518 and :3141 only pass because they use the verbatim bulkResponse.

npm audit fix has the same blind spot when choosing but re-audits the ideal tree before printing (arborist reify _submitQuickAudit) and takes its exit code from that. Suggest the same here: after install_with_manager, run collect_packages_for_audit + send_audit_requests + collect_vulnerabilities over pm.lockfile and derive vulnerable-after-install, remaining, the json fields and the exit code from that, keeping the plan only for the fixing: attribution. Nothing pins the request count for audit fix so this is test compatible; the filtering-mock case above would pin it, and the audit.mdx:109 sentence about versions the fix pulled in should match whatever the code ends up doing.

[alii]

should fix: an npmrc token is only carried onto a bunfig registry when the two files spell the URL byte for byte the same.

ini/lib.rs:1292 replaces the seeded default registry with a fresh object for a registry= line (:1500 does the same for @scope:registry=), the //host/ items get attached to that object at :1616-1647 with a slash insensitive match, and then this compare throws the credentialed object away whenever the raw url bytes differ. Both sides store href verbatim (api/lib.rs:55 deliberately keeps or omits the trailing slash), so https://h/npm-stuff and https://h/npm-stuff/ are different registries here but the same registry for the token match.

That is the #20593 shape this PR closes: .npmrc registry=https://h/npm-stuff plus //h/npm-stuff/:_authToken=T, bunfig registry = "https://h/npm-stuff/" (the reporter added the slash in bunfig precisely because of the path bug). Before this PR the npmrc URL and token were used; now the bunfig URL wins with no token, so an authenticated Artifactory goes from working to 401, and the new npmrc.mdx:8 sentence saying //host/:_authToken still applies to bunfig registries is not true for it. Same for a ~/.npmrc registry=https://npm.corp/ + token with a project bunfig that omits the slash. bun-install-registry.test.ts:465 only passes because it spells the URL identically to the harness bunfig; drop the slash from its registry= line and the token is gone.

config-precedence.test.ts never combines a registry= (or scope) line, an npmrc token and a bunfig registry: the token tests at :177/:207 have a token only npmrc, and :237/:251/:445 use identical strings. Rather than special casing the compare, it seems simpler to have load_npmrc_config hand back the collected // items and apply them to the final default and scope registries after the overlay, with the same host+path match ini already uses (PackageManagerOptions.rs:608-618 does this for the env override); then the seeding and the same-url exemption here can go. Tests: home npmrc registry=<dead> + authLine with bunfig = verdaccio installing @needs-auth/test-pkg, project npmrc registry= verdaccio without slash + authLine with bunfig = verdaccio with slash, and the @scope variant.

should fix: this early return skips the walk at :242-287 that keeps a file at v1 when it carries an integrity-less npm row whose URL is not under the default registry.

The two strict parser checks are gated on at_least(V2) (:2919, :2979) and V3 passes them, and npm_url_needs_integrity is computed from the reader's scope config (:2676-2686), so this brings back the config dependent stamp that #31556 and #31602 removed: same v1 file, same legacy row, someone adds one nested or name@range rule, and a teammate or CI without the writer's scope gets "Missing integrity hash..." and then either "Ignoring lockfile" plus a full re-resolve or a frozen lockfile failure, with nothing pointing at the override. The doc comment at :207-209 still states the invariant this bypasses.

Concrete shape is lockfile-version-2.test.ts:426 plus one rule: writer bunfig has scopes.myorg, v1 lock has "@myorg/foo": [..., "http://host/@myorg/foo/-/foo-1.0.0.tgz", {}, ""], package.json gains "overrides": {"@myorg/foo": {"bar": "1.0.0"}}, bun install --lockfile-only stamps 3, and a reader dir without the scope fails --frozen-lockfile. nested-overrides.test.ts:1120-1146 builds exactly this row and asserts the v3 stamp, but re-reads it in the same dir whose bunfig points at the registry, so it cannot see this; the only cross config reader test has no scoped rule.

Nothing in the parser keys on V3 (object rows are read at any version, :1976-2075, and bun-lock.test.ts:907 already parses them in a v1 file), so running the walk first and leaving such a file at v1 with object rows round trips on this build; the only cost is the error text on older Bun, which cannot read the file either way. If v3 is wanted as a hard marker for external readers, then at least a warning naming the row that would have kept the file at v1. Either way the cross config test above is the one to add. (Also relevant to the v2 vs v3 thread above: this is the one thing v3 changes at parse time.)

[alii]

should fix: with the isolated linker this keeps every old peer-set variant of a package that is still installed, which is most of what a real update leaves behind in .bun.

store_keys (:1040) is StorePathFormatter (Store.rs:382) minus the +peer_hash line at Store.rs:417, and this line then accepts any +16hex suffix on a wanted base. isolated_install.rs:991 hashes every peer's resolved version into the entry name, so bumping react or typescript or vite mints a new +hash dir for every dependent and orphans the previous one, and prune never removes those.

Store on this machine as an example: bun.lock has react@18.3.1 only, .bun still holds react@19.2.5 plus +3f10... variants of lucide-react (42M), @heroicons/react (21M) and html-to-react whose node_modules/react links point at react@19.2.5. This prune removes react@19.2.5 and keeps the three variants, now with dangling links. That contradicts prune.mdx:6/:28/:68, isolated-installs.mdx:94 ("left in place until you run bun prune") and the #21216 line in the body, and bun-prune.test.ts:520/:547 pin the wrong outcome (no-deps has no peers, so no-deps@1.0.0+0123... can never be a real install output). The new test at :2493 only covers the unwanted-base direction.

The exact set is one call away: the 'store: block in isolated_install.rs:234-1155 only reads the lockfile, options and is_filtered_dependency_or_workspace (which prune already uses at :1104), and fmt_store_path is pub(crate). plan_hoisted already does the equivalent by running the real hoister (:702); plan_isolated should build the real Store and drop strip_peer_hash. Test: install with peer@1, bump the peer, install, prune removes the @1 variants; flip :547 to expect removal. If you would rather keep the approximation for now, the docs lines above need to say so.

[alii]

consider: this arm plus the descend(..., false) at :643 means a nested copy of anything that is not npm or git (tarball, folder, link:) can never match, so removable() keeps it and warns, and the note at :868 and prune.mdx:74 tell the user to run bun install and prune again, which cannot change the outcome. A project whose root b is a tarball or link: with a stale node_modules/x/node_modules/b (override re-pointed to $b, or a workspace that dropped its own npm b) warns on every prune forever and prune --production exits 0 with it in place. bun-prune.test.ts:2405 now pins the tarball case as kept so I assume it is deliberate; if so the note and prune.mdx:74 (which says the higher copy is checked from its package.json) should say these are never verified, and it should not keep suggesting an install will fix it. Otherwise the arms are small: tarball/folder is dir exists and package.json name matches, which is all bun install checks for them too (PackageInstall.rs:826), link: is lstat says symlink, plus a link: case and an override-to-tarball case next to :2405.

[alii]

should fix: audit fix now runs the scanner (:1910), but the in-place named update this PR introduces still does not scan what it installs.

bun update <name> where name is only a transitive dependency (the case at bun-update-transitive.test.ts:192) leaves update_requests non-empty, so security_scanner.rs:231 takes the per-request branch, and collect_update_packages (:542) seeds from req.package_id, which is only ever set by bind_update_requests (lockfile.rs:852-883) against the cwd workspace's own dependency slice. For a transitive-only name it stays invalid, the queue is empty and the scanner is spawned with packages: [] while the new tarball is downloaded and linked; a scanner returning [] for an empty list reports the install clean. Before this PR the same command added the name to package.json, so it was bound and scanned; the in-place semantics remove that without adding another seed.

Repro shape: root depends on parent@^1, parent on leaf@^1, leaf@1.1.0 published after the lockfile, scanner marks leaf@1.1.0 fatal, bun update leaf exits 0 and installs it. named.moved (redirected here) is exactly the set of rows that re-resolved, so seeding the collector from the packages those rows now point at, or falling back to scan_all when any request has an invalid package_id, covers any depth and the -r fan out too. One test in bun-update-transitive.test.ts with a two version registry and a fatal scanner would pin it; none of the existing scanner tests move a package that is not declared directly (the matrix runner change pre-declares them).

[alii]

consider: this skip (and the matching one in enqueue_named_updates, install_with_manager.rs:1526) means a package whose only inbound edges are peer edges, i.e. a peer Bun auto-installed, is never re-resolved by anything in the update family. plan_edges never plans it, and redirect() only follows a pin whose from is the peer's current target, which no pin ever has because nothing non-peer points at it. So bare bun update, bun update <parent> --latest and bun update <peer> all leave it where it is, and the named form is a silent exit 0 because matched is set at :1521 before the continue, so reject_unknown_update_requests never fires. A fresh install lands on the newest in-range version (PackageManagerEnqueue.rs:2261 only reuses an entry if one exists), and audit fix does move these edges (audit_fix.rs:402 skips only optional peers), so the two re-point paths disagree on the same edge class.

Repro is the stale() recipe with peer-deps-fixed: root {peer-deps-fixed: 1.0.0, no-deps: 1.0.0}, install, drop no-deps, reinstall (no-deps@1.0.0 survives via the peer edge), bun update leaves it at 1.0.0 where a fresh install gives 1.1.0, and bun update no-deps exits 0 having done nothing, which update.mdx:28 says only happens for a name not in bun.lock. The existing peer tests cannot see it: :855 starts with the peer already at latest, :842 has the root providing it.

Either plan a peer edge when its target has no non-peer inbound edge (enqueue_pinned already strips PEER, and a provided peer still just follows), or state in update.mdx and the kept-differences list that peers only follow, and make bun update <peer-only-name> say so instead of exiting 0 quietly. A stale auto-installed peer test for the three forms would pin whichever.

[alii]

nit: this rule is tested now (bun-update-transitive.test.ts:412) and also applied on the named path (PackageManagerEnqueue.rs:2066), but update.mdx does not mention it, where dedupe.mdx:46 spells out the equivalent. Worth a sentence because it is not uniform: with no-deps@1.0.0 in patchedDependencies, a package depending on no-deps ^1.0.0 is held here with nothing printed, bun update no-deps holds it too, but a root "no-deps": "^1.0.0" under a bare bun update still moves to 1.1.0 (the :2067 pin is gated on update_requests being non-empty) and drops the patch, and audit fix moves it regardless. A kept no-deps@1.0.0 (patched) row like dedupe prints would also make the silent skip visible.

[alii]

consider: the 404/500 test at bun-update-transitive.test.ts:1279 pins that a transitive package whose manifest cannot be fetched is warned about and left alone with exit 0. Fine as a policy, but on a real project the only trace is a warn: GET .../x - 429 line somewhere in the output followed by "Saved lockfile", since this just continues; audit_fix.rs:517 does the same populate and collects a ManifestUnavailable list that gets its own "manifest could not be fetched:" section. Same thing here (a short "N packages could not be checked: a, b" after the updating: block) would stop a rate limited private registry looking like a complete update, and the existing test can assert on it. The direct-dep case is different and still fails non-zero via verify_resolutions, so the exit contract is fine. Separately, neither update.mdx nor the body mention that a bare update now does one abbreviated manifest GET per npm package in bun.lock (about 1,100 on the benchmark app; MANIFEST_CACHE is off for update), which is what people on slow registries will notice first; one sentence plus a pointer at --network-concurrency would do.

[alii]

consider: three things out of sync with the --production remap at :1543. The release notes bullet in the body still says --production on update is an error; what ships is the group filter (tested at bun-update.test.ts:2227, documented at update.mdx:132), so it will get copied into the notes wrong. bun update --help prints both meanings on one screen: UPDATE_PARAMS pulls in SHARED_PARAMS:56 "-p, --production Don't install devDependencies" right next to this new --dev line, while the examples at the bottom say bun update --prod only updates dependencies; prune already has PRUNE_HELP_PARAMS to override the shared text, update wants the same one liner. And completions were not regenerated for update: the update entry in completions/bun-cli.json and the zsh block are byte identical to main, so --dev/--prod/--no-optional/--exact are missing and --production still has the install description. Also worth a line in update.mdx that bunfig install.production is applied with no subcommand check (PackageManagerOptions.rs:527), so on update it still means frozen + no dev, unlike the flag of the same name. No objection to the remap itself.

Rest of what I had, same commit. Four more threads (prune -g, stray publish fixtures, add --filter relations from a stale lockfile, and two robobun fixes folded in). Ignore the #31013/#32974 line in my first summary, the body covers both now.

On shape, for whatever it is worth given you are already fixing things in place: four pieces have no code dependency on the parity work. The isolated waiter list plus the two leak fixes (about 236 lines across Installer/Store/Symlinker/NetworkTask, imports nothing else on the branch), the package-lock migrator (npm_lock.rs uses merge-base APIs apart from MissingWorkspace::Skip and the widened OverrideMap parse signatures) together with the arborist fixtures, which are 44k of the ~100k lines here, overlay_bunfig_install, and nested overrides plus lockfileVersion 3, which is the only part with an open design question and three open upstream PRs. Since main squashes, the one commit is the bisect and revert unit for all of it plus 24 issue closures. Not going to hold the PR on that, but the first two would land on their own today. Related small things: prune is the one new command built beside the linkers rather than on them, which is where the peer-hash thread and the store key format now living in three places (Store.rs:402, prune.rs:1067, pm_licenses_command.rs:521) come from, and your own note at bun-add-filter.test.ts:926 is the same gap; and #29512 (sbom) should be rebased onto reachable.rs after this rather than carrying its own walk, so worth saying it is sequenced after.

[alii]

should fix: bun prune -g unlinks every bun link registration.

PRUNE_PARAMS pulls in SHARED_PARAMS so -g parses (PRUNE_HELP_PARAMS just hides it) and nothing in this file looks at options.global, so init fchdirs into the global dir and prune runs there like any project. But the global dir's node_modules is also where bun link registers packages (PackageManagerDirectories.rs:799-831), and those are not in the global package.json or bun.lock. After any bun add -g x the two files are in sync so the :166 check passes, plan_hoisted's root scan sees each linked symlink, it is not in the expected set, removable() is true for the root tree, and it gets unlinked. Your own "never follows symlinks out of node_modules" test at bun-prune.test.ts:394 is this exact shape. Repro: cd lib && bun link; bun add -g typescript; bun prune -g prints - node_modules/lib and every project using link:lib breaks on its next install. Since -g on prune can only ever remove link registrations (add/remove -g already maintain that dir), I'd reject --global here the way add_remove_with_filter.rs:581 rejects --filter with it, or skip root symlinks pointing outside node_modules, plus a test with a BUN_INSTALL dir like the update -g block at bun-update.test.ts:2627. dedupe -g and audit fix -g on the global project seem fine, though dedupe --help advertising "-g Install globally" is odd.

[alii]

These five dirs (republish-test-1/2/3, publish-version-update, @scoped/pkg-1) look like leftovers of a local bun-publish.test.ts run: localhost:6108 tarball URLs, timestamped this morning, and the test rm -rf's each of them before publishing (bun-publish.test.ts:905, :1249, :1274, :1300), so nothing reads them. Should come out of the PR.

[alii]

should fix: the relation graph comes from the bun.lock on disk before this command runs, while the candidate list above comes from the package.json files, and nothing checks the two agree. The selection is then fixed before install_with_manager runs (filtered_link_targets at :593, PendingWrite at :716), so which package.json files get edited depends on whether the last install happened after the last manifest edit.

Repro: workspaces foo and bar, installed. Add "bar": "workspace:*" to packages/foo/package.json by hand, then bun add zod --filter 'foo...'. First run edits foo only; the install it triggers writes the foo->bar edge; the identical second run edits bar too. Same for the documented bun add zod --filter '...^ui' (filter.mdx:45) after adding a dep on ui to an app: first run edits nothing there. bun install --filter 'foo...' in the same state is right first time because it selects after resolve (install_with_manager.rs:857), and bun run --filter reads the manifests (filter_arg.rs:230), so this is the one --filter path that disagrees with both.

prune and dedupe in this PR already refuse when bun.lock disagrees with package.json (prune.rs:166, dedupe.rs:686), and that diff recurses into members, so the cheapest fix is the same refusal here when a relational selector is present. Or build the edges from the manifests select_targets already parsed (from_dependency_names exists; needs the range check to keep bun-add-filter.test.ts:428), which also removes the needs-a-bun.lock error at :262. Every relational case in bun-add-filter.test.ts installs and then selects against the same manifests, so none can tell the two apart; one test that edits a member between installOk and the add would pin it.

[alii]

This hunk is robobun's #34688 (fixes #25202, still open and not in the list on the PR), and bun.lock.rs:658/734-742 plus the pkg_path rename is #37289; the body mentions neither. Both are the same fixes; this one skips the placement and keys on the dep name where #34688 places without re-enqueueing, and the #25202 shape nests one level and stops, so I don't see a problem with the difference. Worth a Fixes #25202, closing both with credit like #31143/#34407, and lifting their tests: this branch pins the a<->b file: cycle (bun-install.test.ts:10250) but not the self-dependency, npm: alias or workspace:. shapes, and pins the peer fix only through pnpm-lock (pnpm-lock-v9.test.ts:1623), not #37289's package-lock.json case.
