install: a tarball or folder of the project satisfies a range on its name - #47987
The root depends on is-number@7.0.0 as a file: tarball and on a package whose dependency is "is-number": "7.0.0". bun install fetches a second is-number@7.0.0 from the registry and nests it at node_modules/wrapper/node_modules/is-number. When the name is not on the registry, the install fails: error: GET https://registry.npmjs.org/<name> - 404, <name>@<version> failed to resolve. npm installs one copy.
Cause: a range is settled from a registry manifest only. settle_without_manifest (PackageManagerEnqueue.rs) binds a range to a workspace, never to a tarball or folder row, and those rows do not record a version to compare.
Fix
A tarball or file: folder row records the version of its package.json in Meta (the dead man_dir slot, so bun.lockb and the row size do not change). bun.lock writes it as a "version" key in the row's INFO object. A lockfile without the key loads as before. A migration reads the version of each folder, and a changed folder version is written on the next install.
Lockfile::local_sources lists the tarball and folder dependencies of the root, of each workspace, and the tarballs of a folder they declare. It is filled from the parsed manifests, and from the rows of a loaded or cleaned lockfile. In settle_without_manifest, a range on such a name binds to that package when the recorded version satisfies it, before any manifest request. A provider that no row has read yet is read there (a folder) or downloaded (a tarball). A range waits on a tarball's task and is settled when the package is appended, so the order of bun.lock does not depend on the server or on the manifest cache.
In the tree, a range bound to a folder of the project shares the folder placed at the root, as a peer already does. A range the version does not satisfy is resolved from the registry and nested, as today and as npm does.
Verified: test/cli/install/bun-install-registry.test.ts (16 new tests, 13 fail on 1.4.4). Also every file in test/cli/install/ (expectation updates for the new key in 18 files, listed in Notes). Self-reviewed: 27 concerns raised, 19 addressed, the rest listed in Notes.
Background
The resolver settles dependencies in queue order. A git or tarball package is added to the lockfile only once the queue is empty, in the order of the rows that ask for it (RemotePackages). A waiter on a task is re-settled when that task's package is appended (resolve_waiters_of_appended_package). The fix reuses that mechanism instead of adding a queue state.
npm binds an edge to any placed node whose version satisfies the range (arborist/lib/dep-valid.js). Bun already does this for workspaces (linked_workspace_path, workspace_versions). This change is the same rule for the project's other local sources.
Considered relaxing try_satisfies_dedupe in Lockfile::find_package_id: it runs after the manifest arrived, so the 404 case stays broken, and it binds only when the tarball row sorts before its dependent. Considered a name-only side map without persistence: a reload then re-resolves a changed dependent against a row with no version and fetches the registry copy again.
Every project with a tarball or file: folder dependency gets one "version" key per such row the next time Bun saves bun.lock. A registry-only bun.lock is byte-identical (bench/install: 53744 B before and after).
A bun.lock written by an older Bun has no version for its tarball rows. Until the tarball is extracted again (bun update, a changed file: path, --force), a range that is re-resolved against it takes the registry, as today.
A tarball peer still binds by name only (is_peer_provided_locally), and Lockfile::package_version still returns None for tarball rows, so peer range warnings do not change. Git, GitHub and link: rows are not providers. A range bound to a local package is not listed by bun outdated, as a range bound to a workspace is not.
Per settle of a range on a registry-only project: one local_sources.count() == 0 branch, no allocation, no syscall. Per range on a name the project provides locally: one hash probe and one Semver::Version::parse of the recorded string. Instruction counts with cachegrind and release binary size with bloaty were not measured: this container has no release build.
Notes
Test expectation updates for the "version" key on tarball and folder rows: bun-add-filter, bun-add, bun-install-git-deps, bun-install-lifecycle-scripts, bun-install-link-path, bun-install-tarball-integrity, bun-install, bun-install-registry, bun-lock, bun-workspaces, catalogs, config-version, isolated-install, lockfile-only, nested-overrides, migration/migrate, migration/pnpm-lock-v9, migration/yarn-lock-migration, migration/yarn-berry, migration/npm-arborist. Snapshots of the debug lockfile dump (migrate-bun-lockb-v2, bun-workspaces, test/integration/next-pages) carry the renamed Meta field package_json_version.
A package.json without a version records an empty string. bun.lock leaves the key out for it.
Behaviour changes in existing tests:
bun-lock.test.ts "optional dependency the registry does not have, with a local package of that name at the root": the fresh install now binds the optional local: * to the root's folder or tarball (version 1.0.0 satisfies *) and makes no registry request. Frozen and --lockfile-only installs agree with it, which is what the test guards.
bun-lock.test.ts "an optional dependency keeps the root's folder that package-lock.json binds it to": the migrated tree shares the root's folder instead of placing a second copy under the dependent.
bun-pm.test.ts "should list all dependencies when a resolution is longer than 512 bytes": moo's bar@0.0.2 now shares the root's bar tarball of that version, so bun pm ls --all lists no nested bar.
escape-control-characters.test.ts "bun patch lists the candidate resolutions escaped": the registry copy that needs-dep depends on now needs a version the root's tarball does not satisfy (1.5.0), or there is only one dep to patch.
migration/migrate.test.ts: two file: link targets with ranges on each other share the root's folders, so the migrated bun.lock has no nested rows to cut a cycle in. A registry package whose range package-lock.json binds to a root folder shares that folder's row.
Scope:
Providers: file: tarball, URL tarball and file: folder dependencies of the root, of a workspace member, and the tarballs of a folder that one of them declares (Features::is_main, is_workspace, is_folder parses, and Lockfile::index_all_local_sources for loaded rows). A tarball that a registry package declares is not a provider (tested). A folder that a folder declares is read without its package.json, so it has no version and is not a provider.
The binding is keyed by the dependency name (the alias). A row whose package.json name differs from the alias is not shared, as in npm. The first declaration of a name is the provider.
* binds to a local package whatever its version, as it does for a workspace.
A root tarball that fails to extract or download: the ranges that waited on it are enqueued again and take the registry (forget_failed_tarball_task, all three failure arms; tested for a URL tarball).
A file: path of a provider that moves on an existing bun.lock, or a provider that package.json drops: the dependents stay bound to the old row until they are resolved again, as a moved registry dependency's dependents do.
A range that a local version does not satisfy is requested from the registry once its provider has arrived, not by the look-ahead. The request is late by the tarball's download time.
Self-review concerns left as they are: link: rows as providers (a different row kind, out of scope), the migrators recording tarball versions from package-lock.json (the next install records them when the tarball is read; folder versions are read from disk), and a single accessor over package_version (peer semantics unchanged here).
Measurements:
Meta layout: a const assert pins offset_of!(Meta, package_json_version) == 12, the slot that is empty in every older bun.lockb.
Registry requests for the local name in the new tests: 0 in the three orders, the folder case, the workspace case and the URL case. 1 in the out-of-range case, where npm also fetches.
bench/install (registry only): bun install --lockfile-only --frozen-lockfile leaves bun.lock byte-identical, 53744 B.

…name
A tarball or file: folder row records the version of its package.json,
persisted as a "version" key in bun.lock. A range on a name that the
root or a workspace provides from such a dependency binds to that
package when the version satisfies it, before any manifest request, and
waits for the tarball when it is still downloading.
Bun now records package.json versions for tarball and folder dependencies. During installation, matching local packages can satisfy npm dependency ranges without registry resolution. The change also updates lockfile serialization, migration handling, documentation, and install tests.

Explanation
The title names the main behavior change: a tarball or local folder of the project can satisfy a version range on its package name. The changeset implements this in the resolver (PackageManagerEnqueue.rs, lockfile.rs, Package.rs), records package.json versions in the lockfile, and adds tests for range matching. The title is specific and matches the change, though it is somewhat long at 73 characters.
Full details: Description check
Explanation
The description follows the repository template. It has a "What does this PR do?" section with a Problem, Fix, Background, Downsides, and Measurements. It also has a "How did you verify your code works?" section that lists the new registry tests, the 1.4.4 failure count, and the expectation updates across test/cli/install/. The Notes block lists every affected test file and the behaviour changes in existing tests. The author states that a container build limited measurements. The bench/install byte count is recorded. Cachegrind and bloaty were not measured. Test runs for 15 install test files were deferred to CI, and the evidence block says so. The description is detailed and matches the scope in the raw summary. The only gap is that the verification section does not state whether the new tests pass on the patched build. The text says 13 of 16 new tests fail on 1.4.4, which covers the before state only.

- Around line 1758-1759: When updating package_json_version through
from_lockfile, revalidate range edges that depend on the changed folder and
re-resolve any edge the new version no longer satisfies, so dependents select a

- Around line 1750-1751: Update the version-change handling around
`summary.folder_versions_changed` so a transition from an empty `from_version`
to a nonempty `to_version` is recorded and causes the lockfile row to be saved.
Preserve compatibility with older lockfiles that lack version metadata;
distinguish that missing metadata from a known version change rather than
treating every absent value as a change.

- Around line 3493-3498: Update the local-source lookup that constructs
`Task::Id::for_tarball` to use the effective provider version after applying

Review comments at @src/install/PackageManager/runTasks.rs:
- Line 1067: Update the failure handling around `forget_failed_tarball_task` to
distinguish registry-fallback waiters from requests whose own tarball source
failed. Keep fallback waiters eligible for registry resolution after an optional
workspace tarball fails, while preserving failure status for requests whose own
source failed.
- Around line 395-397: Update the dependency filter in the `runTasks` flow to
retry catalog range waiters based on their effective request, rather than
excluding every dependency whose stored version tag is not Npm. Preserve the
existing behavior for unrelated non-Npm dependencies while allowing
catalog-backed ranges waiting on a failed optional tarball to retry against a
satisfying registry version.
Review comments at @test/cli/install/bun-install-registry.test.ts:
- Line 3474: Update the subprocess result handling at the `proc.stdout.text()`
call to collect stderr and verify the process exits successfully before
accepting the `LOCAL` output. Preserve the existing output assertion and fail
the test when the subprocess exits unsuccessfully.
- Around line 3844-3848: Update the `tarball` call that creates `wrapper` in the
frozen-install test so the wrapper’s runtime entry point requires `no-deps`
instead of exporting a local value. Keep the declared dependency and existing
test setup intact so the runtime assertion verifies that `wrapper` can resolve
and load its dependency.

A package that the root, a workspace, or a `file:` folder of theirs installs from a tarball or a `file:` folder also satisfies the other packages that depend on that name, when the `version` in its `package.json` satisfies their range. As in npm, `bun install` then installs one copy and does not ask the registry for the name. A range that the version does not satisfy is resolved from the registry as usual.

Retry catalog range waiters after a tarball fails.
If an optional tarball fails while a catalog-backed range waits for it, this filter drops the catalog row. The install can then fail even when the registry has a satisfying version. Retry waiters based on their effective request, not only their stored tag.

Update the dependency filter in the `runTasks` flow to retry catalog range
waiters based on their effective request, rather than excluding every dependency
whose stored version tag is not Npm. Preserve the existing behavior for
unrelated non-Npm dependencies while allowing catalog-backed ranges waiting on a
failed optional tarball to retry against a satisfying registry version.

Keep registry waiters eligible after an optional tarball fails.
When an npm update waits on an optional workspace tarball, its failure marks the update request failed before registry fallback runs. The command can then abort even if the registry resolves the range. Distinguish fallback waiters from requests whose own source failed.

🔴 Users who change a workspace's (or a root-declared file: folder's) dependency away from a local tarball or folder can still get the old local package bound to the new range after merging. index_all_local_sources() at install_with_manager.rs:502 indexes the workspace rows still loaded from bun.lock, before the workspace is re-read; the later re-parse keeps the first entry (lockfile.rs:851), so local_source_of_range reads the stale row's old resolution and shares it. Fix: entries must never point at rows a re-parsed package no longer declares, e.g. drop entries whose row lies in the replaced dependencies slice when read_package_json_from_disk replaces a package (folder_resolver.rs:340) and re-index. [also at: src/install/lockfile.rs:853 - After merging, an install that re-reads a changed workspace or root file: folder can bind a range to a stale, no-longer-declared tarball package, or miss the newly declared one.]
Why this was flagged
A workspace packages/app was installed with "no-deps": "file:../../no-deps-1.5.0.tgz" and bun.lock holds that tarball package T with "version": "1.5.0". The user edits it to "no-deps": "^1.0.0" and runs bun install. The Diff reports a change, so install_with_manager.rs:502 runs index_all_local_sources(), which walks the workspace package's dependencies slice as loaded from bun.lock (lockfile.rs:884-892) and records local_sources[no-deps] = R_old. The workspace is then re-read by read_package_json_from_disk; Package::parse calls index_local_sources (Package.rs:3492) but only writes a name when !entry.found_existing (lockfile.rs:851), so R_old stays. When the new row no-deps@^1.0.0 is bound, settle_without_manifest reaches local_source_of_range (PackageManagerEnqueue.rs:3487-3524): resolutions[R_old] is T, shares finds the name equal and 1.5.0 satisfying ^1.0.0, and returns Settled::Package(T). The range is bound to the tarball the workspace no longer declares, the registry is never asked; on the base branch the range resolves from the registry.
Verification: install_with_manager.rs:502 calls manager.lockfile.index_all_local_sources()? before any workspace is re-read. Re-parsing the workspace (Package.rs:3491-3492) only calls index_local_sources(self.dependencies, true), which keeps the first entry (lockfile.rs:851-853). settle_without_manifest (PackageManagerEnqueue.rs:3630-3636) then calls local_source_of_range with binds = true.

🔴 Users who bump the version of a vendored file: folder (or re-read tarball) keep transitive ranges bound to it even when the new version no longer satisfies them. Package.rs:1750-1760 records the new version into the loaded row and sets folder_versions_changed, but nothing unbinds the Npm-ranged rows already resolved to that package, and locked_version_is_out_of_range (Package.rs:1912) only checks ResolutionTag::Npm. …
Why this was flagged
…Fix: when a local-source row's recorded version changes (generate_folder, and the moved tarball branch in processDependencyList.rs:212), re-check every Npm-ranged row bound to that package with recorded_version and unbind or mark refreshing those whose range it no longer satisfies, and extend locked_version_is_out_of_range to resolutions where records_package_json_version() holds. A fresh install (rm bun.lock) sends the same range to the registry, so incremental and fresh installs diverge.
Root package.json has "foo": "file:vendor/foo" (vendor/foo/package.json version 1.0.0) and a registry package bar that depends on foo@^1.0.0. The first install binds bar's row to the folder package P through local_source_of_range (PackageManagerEnqueue.rs:3516-3518) and writes "foo": ["foo@ file:vendor/foo", { "version": "1.0.0" }] with no bar/foo row. The user edits vendor/foo/package.json to version 2.0.0 and runs bun install again.
Verification: normal — triggered whenever a user bumps the version of a file: folder that a registry dependent's npm range was bound to by this PR and runs an incremental bun install. Mechanism verified: (1) On the first install local_source_of_range (src/install/PackageManager/PackageManagerEnqueue.rs:3516-3518, range.satisfies(version…).then_some(Settled::Package(package_id))) binds bar's foo@^1.0.0 row to the folder package P; the PR's own test "a file: folder is shared" shows the result (["no-deps@ file:vendored", { "version": "1.5.0" }], no nested row).

🔴 Hoisted installs can now fail with "refusing to install dependency ... with unsafe folder path" when a workspace's file: folder outside the project satisfies a registry package's range. The range row is bound to the Folder package, but Tree.rs:1573-1598 only dedupes it against an ancestor placement; a workspace's folder stays in the workspace tree, so the folder is placed again under the registry package. PackageInstaller.rs:1915-1927 treats that nested row as untrusted and refuses a path with ... Fix: a range bound to a project folder must install from the folder's trusted placement (hoist it with the folder, or treat the row as trusted), also for in-project folders, which now get a second copy.
Why this was flagged
Workspace packages/w declares "lib": "file:../../../shared/lib" (folder outside the project, package.json version 2.0.0) and a registry dependency p whose manifest lists "lib": "^2.0.0". Package.rs:3492 indexes w's row in local_sources; when p's row is resolved, PackageManagerEnqueue.rs:3633 and shares (3500-3521) bind it to the Folder package instead of asking the registry. In the hoisted tree w's own Folder row never hoists (Tree.rs:1598 places it in w's tree), and p is hoisted to the root tree, so for p's row the new clause at Tree.rs:1573-1576 gets Placement from hoist(hoist_root_id), falls through, and Tree.rs:1598 places the Folder package a second time at node_modules/p/node_modules/lib. The hoisted linker then installs that nested row with is_transitive true, bin_target_escapes_package_dir("../shared/lib") true, and is_trusted_folder_dependency(p_row) false because p is a registry package, so it prints "refusing to install dependency lib with unsafe folder path" and self.fail(...) (PackageInstaller.rs:1915-1927). On the base branch p's lib@^2.0.0 resolves from the registry and installs.
Verification: Tree.rs:1576 hoist(hoist_root_id=0) walks p's tree then tree 0, finds no lib, so line 1598 places the Folder package again at node_modules/p/node_modules/lib. PackageInstaller.rs:1915-1927 then print refusing to install dependency <b>lib<r> with unsafe folder path and self.fail(...). On the base branch, p's lib@^2.0.0 would simply resolve from the registry and install cleanly.

🔴 Users whose lockfile pins a file: folder through an override get a different lockfile after rm bun.lock && bun install than after an incremental install. On a fresh install, Package.rs:3493 indexes the tarball rows of every folder parsed with a live resolver, which includes an override-selected folder reached via from_root_rule at PackageManagerEnqueue.rs:3944. On reload, index_all_local_sources (lockfile.rs:427-445) only walks folders a root or workspace row declares, so that folder's tarballs are no longer local sources. Fix: derive both indexes from one predicate (e.g. is_local_declarer, which already includes is_override_selected_package) so the parse-time and reload-time local_sources cover the same folders. [also at: src/install/lockfile/Package.rs:3494 - Users can get a different lockfile for the same project depending on whether bun.lock already existed, when an override points a name at a file: folder that itself declares a tarball dependency.; src/install/lockfile.rs:953 - Users whose root overrides or resolutions point a name at a file: folder can get a different bun.lock depending on whether bun.lock already existed.; +1 more]
Why this was flagged
Root package.json has overrides: { "x": "file:./vendored-x" }, a registry package depends on x, and vendored-x/package.json declares "y": "file:../y.tgz" while another package depends on y@^1 (satisfied by the tarball's version). On a fresh install the override row is resolved through from_root_rule (PackageManagerEnqueue.rs:3944-3949), so Package.rs:3493-3494 calls index_local_sources(self.dependencies, false) and y becomes a local source; the y@^1 range binds to the tarball. With a bun.lock present, index_all_local_sources (lockfile.rs:423-451) rebuilds the map from only ResolutionTag::Root | ResolutionTag::Workspace rows and the folders those rows declare; the override-selected folder is declared by a registry package's row, so it is skipped. A dependent on y added later therefore resolves from the registry and nests a second copy, so bun.lock depends on install history. On the base branch neither path shares a tarball, so the two installs agree.
Verification: On a fresh install, from_root_rule (PackageManagerEnqueue.rs:3944-3949) leads to Package.rs:3493-3494, where index_local_sources(self.dependencies, false) indexes the override-selected folder's tarball rows. On an incremental install, index_all_local_sources (lockfile.rs:891-919) only walks Root | Workspace packages and their Folder rows, so the tarball y row is not indexed.

🔴 Workspace members that depend on a project file: folder through a catalog: entry get a second nested copy of the folder instead of sharing the root's. The new dedupe at Tree.rs:1573-1574 tests the stored row tag dependency.version.tag == Npm, but a catalog row keeps tag Catalog in the buffer even though its resolved range (tag Npm) is what bound it to the folder in local_source_of_range. Fix: decide by the resolved range, e.g. catalogs.resolve_range(buf, dependency).tag == Npm as is_in_peer_range at Tree.rs:1872 already does, or dedupe any non-peer row whose resolution is a Folder the ancestor edge provides regardless of tag.
Why this was flagged
Root package.json has "foo": "file:./vendor/foo" (version 1.2.0) and "workspaces": { "packages": ["packages/*"], "catalog": { "foo": "^1.0.0" } }; packages/app declares "foo": "catalog:". asked_version at PackageManagerEnqueue.rs:1867-1881 replaces the catalog row's version with the Npm range, so settle_without_manifest calls local_source_of_range and binds app's row to the folder package (Settled::Package). In the tree builder the row read from builder.dependencies still has tag Catalog, so the condition at Tree.rs:1573-1574 is false, the ancestor loop at :1582-1594 finds no matching ancestor edge, and the row is placed in app's own tree by hoist(next_id) at :1598, yielding packages/app/node_modules/foo as a second copy. The same row declared as "foo": "^1.0.0" is deduped to the root's node_modules/foo. On the base branch the catalog row resolved from the registry, so no folder copy existed under app.
Verification: Triggered when a workspace member declares the project folder's name via catalog:. Catalog rows keep tag Catalog in the dependency buffer, so the new dedupe at Tree.rs:1573-1574, dependency.version.tag == VersionTag::Npm, is false for the catalog row and the hoist(hoist_root_id) call is skipped; the folder package is placed again inside the workspace's own tree, a second copy instead of the shared root copy.

🟡 nit (optional): the requireResult helper spawns with stderr: "pipe" but only reads stdout, so a child that writes more than the pipe buffer to stderr deadlocks the test instead of failing it. Fix: drain both pipes together with Promise.all([proc.stdout.text(), proc.stderr.text(), proc.exited]) as the sibling install helper at bun-install-registry.test.ts:3466 does, and assert on the exit code. [also at: test/cli/install/bun-install-registry.test.ts:3509 - nit: a failing require in the new local-source tests reports only an empty string, and the child's stderr is never drained.]
Why this was flagged
requireResult at test/cli/install/bun-install-registry.test.ts:3464-3475 pipes stderr and never reads it, and never awaits proc.exited or checks the exit code. If require(name) throws with a long stack (for example when the shared package was not installed, which is what these tests check) the child blocks once the stderr pipe fills, and the test hangs until the timeout rather than reporting the wrong stdout. The repository's test rules call for draining stdout and stderr concurrently with proc.exited; the neighbouring install helper at line 3466 follows that pattern. The base branch does not have this helper.
Verification: nit — triggered only if the bun -e "console.log(require(...))" child writes more than the OS pipe buffer (~64KB) to stderr before exiting. test/cli/install/bun-install-registry.test.ts:3466-3475 requireResult spawns with stderr: "pipe" and then only does return (await proc.stdout.text()).trim(); — stderr is never drained, proc.exited is never awaited and the exit code is never asserted.

🟡 nit (optional): after migrating an npm lockfile, a file: folder nested inside a dependency can get a wrong "version" written into bun.lock. read_folder_versions at src/install/lockfile.rs:870 joins every Folder resolution path with the top-level dir, but a nested folder's path is relative to its dependent (npm_lock.rs:625 stores path_in_dependent). Fix: only read package.json for folders whose path is top-level relative (the root's, a workspace's, or a trusted folder's rows), or resolve the path against the declaring package's directory, so the recorded version always comes from the folder the row names. [also at: src/install/migration.rs:273 - nit: after migrating another lockfile, a file: folder that only another folder declares gets a "version" in bun.lock that a fresh install never writes. read_folder_versions fills every Folder row, but the fresh path builds such nested rows as bare packages at PackageManagerEnqueue.rs:3975-4003 with no version.]
Why this was flagged
A package-lock.json where a registry package declares a nested file:lib folder is migrated; npm_lock.rs:622-626 records the Folder resolution path as lib, relative to that dependent. finish_migration then calls read_folder_versions (src/install/migration.rs:273). At src/install/lockfile.rs:870-878 that path is joined with the top-level dir and <project>/lib/package.json is read. When the project happens to have such a file, its version is appended to the nested folder's row and written to bun.lock as "version" (bun.lock.rs:739). On the base branch no version key exists, so nothing wrong is recorded. The version is not consulted for resolution because nested folders are never in local_sources, so the effect is a wrong value in the committed lockfile rather than a wrong install.
Verification: nit. Trigger: a package-lock.json is migrated in which a registry package declares a file: folder, and the project root contains a directory at the same relative path with a package.json. read_folder_versions (src/install/lockfile.rs:870-878) joins every Folder row's path with the top-level dir, so bun.lock gets a "version" a fresh install never writes. Nothing consumes the wrong value.

file:folder row records theversionof its package.json inMeta(the deadman_dirslot, sobun.lockband the row size do not change).bun.lockwrites it as a"version"key in the row's INFO object. A lockfile without the key loads as before. A migration reads the version of each folder, and a changed folder version is written on the next install.Lockfile::local_sourceslists the tarball and folder dependencies of the root, of each workspace, and the tarballs of a folder they declare. It is filled from the parsed manifests, and from the rows of a loaded or cleaned lockfile. Insettle_without_manifest, a range on such a name binds to that package when the recorded version satisfies it, before any manifest request. A provider that no row has read yet is read there (a folder) or downloaded (a tarball). A range waits on a tarball's task and is settled when the package is appended, so the order ofbun.lockdoes not depend on the server or on the manifest cache.test/cli/install/bun-install-registry.test.ts(16 new tests, 13 fail on 1.4.4).
