Yarn Berry supports negated workspace patterns (e.g. "workspaces": ["packages/*", "!packages/legacy"]), leaving excluded members out of the project and never installing their dependencies. Previously, workspace discovery ignored the ! pattern, which resulted in:
Reporting findings for fallback dependencies declared solely by excluded members.
Enhanced resolveWorkspacePackageJsonPaths to support negated patterns by expanding ! patterns and excluding any matching manifests or descendant directories from the matched set.
Added isClassicYarnProject to distinguish Yarn Classic lockfiles (which do not support negation) from Yarn Berry, npm, and pnpm (which do).
Forwarded options?: { allowNegation?: boolean } through readWorkspaceMemberManifests and readDirectDependencyNames.
src/parsers/yarn-lock.ts:
Replaced the custom glob loop in readWorkspacePackages with resolveWorkspacePackageJsonPaths, passing allowNegation: isBerry.
Updated loadSeeds and buildYarnWorkspaceMap to respect Berry workspace negation while keeping Classic behavior unchanged.
Tests:
Added tests in tests/parsers/yarn-lock.test.ts verifying that negated patterns on Yarn Berry exclude omitted members from findings and workspace maps, that removing the exclusion fails the assertion, and that Classic Yarn behavior is preserved.
Added tests in tests/utils/workspace-patterns.test.ts covering negated patterns across npm, pnpm, and Berry, as well as Classic Yarn.
Added a test in tests/remediation/fix-commands-workspace-scoping.test.ts ensuring fix commands never target workspaces excluded by negation.

Workspace exclusions are supported for npm, pnpm, and Yarn Berry projects, even when exclusion patterns appear before inclusion patterns. Excluded workspaces are omitted from package results and workspace-scoped fix plans.
Bug Fixes
Yarn Berry exclusions are recognized when lockfiles contain a comment preamble. Excluding a named directory also removes descendant workspaces; wildcard exclusions apply only to matching paths.
Classic Yarn retains its existing behavior of including workspaces matched by exclusion patterns and supports partial-glob workspace matching.
Yarn Berry workspace discovery now excludes packages matched by negated patterns. Yarn Classic retains its existing behavior. The shared resolver applies negated patterns to npm and pnpm workspace definitions. Workspace maps, dependency seeding, and fix-command scoping use the resolved workspace set.
Yarn detects lockfile format and passes the Berry setting through workspace discovery and dependency seeding. Tests cover Berry exclusions, Classic behavior, workspace maps, and a fix command scoped to an included workspace.
OWASP/cve-lite-cli#1531: Yarn discovery now uses the shared resolver, which expands intermediate wildcard patterns described in this issue.

Merge Risk: Low · previous review b35e0
The change makes Yarn Berry negated workspace patterns work as intended while leaving Classic Yarn behavior unchanged. The only remaining concern is a minor performance cost from repeated lockfile reads on large projects. It is safe to merge, with an optional follow-up to reuse the detection result.

Explanation
I find no unrelated change at the current head. The reported changes cover workspace pattern resolution, Yarn workspace discovery, and tests for those behaviors.

Full details: Closes Keyword Matches Scope
Explanation
Yarn Classic users can get different findings and workspace fix targets, so closes #1538 would close the issue before all its work is complete. Issue #1538 asks for Berry exclusions from findings and fix commands, unchanged Classic behavior, a test sensitive to removing the exclusion, and a check of npm and pnpm behavior. The PR adds coverage for the Berry case and npm and pnpm. But it does not preserve Classic behavior: the base parser treated packages/pkg-* as a literal path, while the new shared resolver expands it for Classic (src/parsers/yarn-lock.ts:140-149, src/utils/package-json.ts:248-257). The new Classic test expects the resulting dependency and workspace mapping (tests/parsers/yarn-lock.test.ts:1091-1117).
Resolution
I recommend preserving the previous Classic workspace discovery behavior and updating the Classic test. If that work is out of scope, replace closes #1538 with Refs #1538.

Keep symlinked workspaces consistent across positive and negated patterns.
A literal positive pattern can add a symlinked workspace because fs.statSync follows the link. A wildcard negation skips that same directory because childDirectoryNames rejects symlinks. The excluded workspace can therefore remain in scan results and suggested fix commands.
Make wildcard expansion apply the same symlink policy as literal expansion without recursively following links that can loop. Add a regression fixture with a symlinked member, a positive literal pattern, and a wildcard negation.

Thanks @coder-Yash886, the core fix works. With "workspaces": ["packages/*", "!packages/legacy"] and only legacy declaring node-fetch@2.6.0, main reports a HIGH and tells you to upgrade it in legacy; on your branch Berry reports nothing, and Classic is unchanged. The tests catch the negation, the Berry routing and the Classic routing when I take each one out.
The main thing to know first: #1532 is approved and lands ahead of this, and it replaces the hand-written Yarn glob loop with a shared resolveWorkspacePackageJsonPaths for every Yarn project. This PR adds a function with the same name and moves only Berry onto it, so the two conflict in yarn-lock.ts and package-json.ts. Once #1532 is in, I think most of this collapses to passing { allowNegation: berry } into its resolver, and the Classic-only loop can go, since #1532's resolver already handles Classic globs better than the old trailing-* loop. Could you rebase onto it then? When resolving, please keep #1532's root-manifest entry in buildYarnWorkspaceMap.
A few things to sort out along the way:
Two behaviour questions I'd like pinned with tests rather than left implicit:
Negation now applies to npm and pnpm workspace patterns as well, and the test that pinned "ignores a negated pattern, which fails in the safe direction" was deleted. I think npm does honour ! here, so that may well be right, but it's a change beyond Berry. Could you say in the PR which managers you checked, and replace the deleted test with one that pins the new behaviour?
!packages/legacy also drops packages/legacy/sub when that folder was matched by packages/**. Nothing tests that, and I'm not sure Berry does the same without !packages/legacy/**. Either a test showing it matches Berry, or drop the pruning.

Restore the merge-base expansion rules for the Classic path. Scope the new

Thanks @coder-Yash886, this round sorts out most of what I raised. The cache is gone, there's one isYarnBerry that both files share, the unused options arguments are gone, Classic now goes through the shared resolver, and the npm/pnpm negation test is back. npm and pnpm both honour !apps/legacy, so applying negation beyond Berry is right.
On the descendant question I left open last time, Yarn 4.14.1 answers it, and Berry does prune. With ["packages/**", "!packages/legacy"], yarn workspaces list shows only the root and packages/web, so packages/legacy/sub isn't a workspace. npm and pnpm keep legacy/sub, so your new test is right for them. On this branch, a Berry project where only legacy/sub declares minimist@1.2.5 gets a CRITICAL, a fix telling you to upgrade legacy-sub, and exit 1, so CI fails on a package Berry never installs.
Berry follows fast-glob's rule here: a negated pattern ending in a plain name, like !packages/legacy, also drops everything under it, while one ending in a wildcard, like !packages/leg* or !packages/*, only drops the directories it matches. Yarn agrees on all three. So the old pruning wasn't quite right either, because it pruned for every negation.
Last thing, on #1532: it's approved and lands ahead of this, and the two still conflict in yarn-lock.ts and package-json.ts. The resolution is small. Take your side of package-json.ts, and in buildYarnWorkspaceMap keep #1532's root-manifest entry while passing your isBerry through. With that the full suite passes on the two together. Once #1532 is in, could you rebase onto it?

I'd avoid the unguarded readFileSync in the fallback, because a read error can throw out of workspace discovery.
When isBerry is undefined, this line reads the lockfile with no try/catch. buildYarnWorkspaceMap guards the same read. This path has no guard. An unreadable lockfile throws here instead of falling back to Classic behavior.
Current callers pass isBerry explicitly, so the risk is low. The fallback still behaves differently from the guarded path.

This test name says one thing and the test asserts another.
The title says npm and pnpm do not prune descendants "unless explicitly matched by a negated wildcard". The body only covers a plain-name exclusion with no wildcard case. The test also has no pnpm setup. It uses package.json workspaces without a yarn.lock, which is the npm path.
I'd rename the test to match what it checks. I'd also add a pnpm-workspace.yaml variant so the pnpm claim is covered.

I'd cache the Yarn lockfile detection, because the resolver now reads yarn.lock twice per call.
Both defaults call fs.readFileSync on the full lockfile, one in isClassicYarnProject and one in isYarnBerryProject. This happens each time resolveWorkspacePackageJsonPaths runs without options. Callers that omit options include readDirectDependencyNames and readWorkspaceMemberManifests. On a large Berry lockfile, this means repeated multi-megabyte reads per scan.
I'd read the lockfile once and derive both defaults from the same result:
The cleaner option is a single detectYarnFlavor(projectPath) helper that returns "berry" | "classic" | "none". It would also make the missing-lockfile case explicit. Without yarn.lock, negation is currently on, but pruning is off.

Thanks @coder-Yash886, the fix itself is right. I checked it against real Yarn 4 and Yarn 1 lockfiles: on Berry an excluded member no longer produces findings or gets named as a parent (main reported a critical from it and exited 1), the descendant rule matches what Yarn 4 does for both !packages/legacy and !packages/leg*, and Classic keeps the excluded folder as a member, the way yarn 1 does. Every alias test from main is back, the suite passes and it builds.
A short last round:
Descendant pruning has no test through the Yarn parser. If I set pruneDescendants to false in readWorkspacePackages, every test still passes. Could you add a scan-level case for the packages/legacy/sub tree from my last review: no finding from legacy/sub, nothing naming legacy-sub? And a small case where !packages/legacy keeps a sibling packages/legacy-old, so the trailing separator in the prefix check is pinned.
Dead code.isClassicYarnProject and isYarnBerryProject have no callers, and the fallback detection in readWorkspacePackages is never reached because both callers pass a boolean. Could you drop all three? That also leaves Berry worked out in one place, which was the ask from my first review.
The PR description still talks about forwarding allowNegation through the manifest readers, which is gone, and doesn't mention the descendant rule or which package managers you checked. Could you bring it up to date?
Minor, take it or leave it: the .replace(/^\.\//, "") is redundant since path.join already normalises it, and the two signature reflows in package-json.ts are whitespace only.
After that it waits on #1532 and the rebase onto it.

closes #1538.
Summary
Yarn Berry supports negated workspace patterns (e.g.
"workspaces": ["packages/*", "!packages/legacy"]), leaving excluded members out of the project and never installing their dependencies. Previously, workspace discovery ignored the!pattern, which resulted in:yarn workspace legacy add ...), which Berry rejects.Changes
src/utils/package-json.ts:resolveWorkspacePackageJsonPathsto support negated patterns by expanding!patterns and excluding any matching manifests or descendant directories from the matched set.isClassicYarnProjectto distinguish Yarn Classic lockfiles (which do not support negation) from Yarn Berry, npm, and pnpm (which do).options?: { allowNegation?: boolean }throughreadWorkspaceMemberManifestsandreadDirectDependencyNames.src/parsers/yarn-lock.ts:readWorkspacePackageswithresolveWorkspacePackageJsonPaths, passingallowNegation: isBerry.loadSeedsandbuildYarnWorkspaceMapto respect Berry workspace negation while keeping Classic behavior unchanged.Tests:
tests/parsers/yarn-lock.test.tsverifying that negated patterns on Yarn Berry exclude omitted members from findings and workspace maps, that removing the exclusion fails the assertion, and that Classic Yarn behavior is preserved.tests/utils/workspace-patterns.test.tscovering negated patterns across npm, pnpm, and Berry, as well as Classic Yarn.tests/remediation/fix-commands-workspace-scoping.test.tsensuring fix commands never target workspaces excluded by negation.
