fix: print a runnable within-range refresh command on yarn berry - #1547
On a Yarn Berry (v2+) project the within-range fix command read yarn upgrade <pkg>, which Berry does not have, so the command we print failed when pasted, and --fix spawned the same thing. The Yarn upgrade builder in src/remediation/fix-commands.ts had no Berry branch, although the scanner already tells Classic and Berry lockfiles apart in src/parsers/yarn-lock.ts.
What Yarn 4 actually accepts
Checked on Yarn 4.14.1 against the examples/yarn-berry lockfile (follow-redirects is transitive via axios):
yarn up follow-redirects exits with Usage Error: Pattern follow-redirects doesn't match any packages referenced by any workspace and changes nothing.
yarn up -R follow-redirects moves the lock entry from 1.14.0 to 1.16.2 and leaves package.json alone, which is exactly the within-range refresh we want.
In a workspace, yarn workspace app up -R follow-redirects works the same way; without -R it fails identically.
So the Berry form is yarn up -R <pkg>, and yarn workspace <name> up -R <pkg> for a member. On a copy of examples/yarn-berry-workspace (lock pinned at follow-redirects@1.14.0), yarn workspace app up -R follow-redirects moved the entry to 1.16.2.
-R was added in Yarn 3.0.0 ("yarn up now supports a new -R,--recursive flag"). A project on Yarn 2 therefore has no command that refreshes a transitive package, and such a project now gets the finding in the skipped list with the reason and the Yarn 3+ steps (yarn set version stable, then yarn up -R <pkg>) instead of a command Yarn 2 rejects. Yarn 2 is recognised from, in order:
an active yarnPath in .yarnrc.yml (parsed as YAML, so quotes and trailing comments are fine), which is what yarn runs, unless ignorePath: true;
otherwise packageManager: yarn@2.x in the root package.json;
with no pin at all, the lockfile's __metadata.version (LF or CRLF): 4 was written by Yarn 2.x and 3.0 (LOCKFILE_VERSION in yarnpkg/berry Project.ts is 4 at tags 2.4.3 and 3.0.0, 5 at 3.1.0, 6 at 3.6.4, 8 at 4.0.0), so an unpinned version-4 lockfile counts as Yarn 2. An unpinned Yarn 3.0 project gets the guidance too; pinning it (packageManager: yarn@3.x) restores the command.
with no pin and no readable __metadata.version, the Yarn version is unknown: the refresh is skipped too, and the reason says the version could not be determined (run yarn up -R <pkg> if yarn --version is 3 or newer, otherwise yarn set version stable first) rather than calling the lockfile old.
An unpinned project with a version-5+ lockfile gets yarn up -R. That lockfile was last written by Yarn 3.1 or newer, which is the project's Yarn unless someone has since switched to an older global binary without pinning it. Yarn 2.4.3 does read newer lockfiles, so this is an inference, not proof of the binary; if it is wrong, Yarn 2 rejects the command (Unknown Syntax Error: Unsupported option name ("-R"), exit 1, lockfile untouched) and --fix stops on the non-zero exit.
Accepted limitations
Yarn 2 has no command that refreshes a transitive package (yarn up without -R only accepts packages a workspace declares), so a Yarn 2 project gets the finding in the skipped list with the reason and the Yarn 3+ steps instead of a command. This is why the PR uses Refs, not Fixes: fix(yarn): Berry fix commands use yarn upgrade, which Berry does not support #1537 asks for a runnable command on Berry, which Yarn 2 cannot have.
An unpinned project with a version-4 lockfile, or with no readable lockfile version, is skipped with guidance even when it actually runs Yarn 3.0 or newer; pinning the version restores the command.
A real scan of a Berry workspace prints the root-level yarn up -R <pkg> (which runs and refreshes the whole project) rather than the member-scoped form, because the transitive resolver does not read workspace paths for any package manager. That is tracked in Resolve workspace paths for transitive remediation #1548.
Change
isYarnBerryLockfile(filePath) in src/parsers/yarn-lock.ts wraps the existing isYarnBerry(content) check for a path; an unreadable file counts as Classic (the same file was parsed by this scan moments earlier).
buildSuggestedFixCommandPlan reads the flavour once, stores it as plan.yarnBerry, and passes it to buildYarnUpgradeCommand, which prints yarn up -R <pkg> / yarn workspace <name> up -R <pkg> on Berry. Both call sites (first pass and the rebuild from merged workspaces) use it.
--fix: buildParentUpdateApplyArgv in src/utils/fix-runner.ts takes plan.yarnBerry and spawns the same verbs, so the printed and the executed command match. Classic keeps yarn upgrade everywhere.
New example examples/yarn-berry-workspace: a root with workspaces: ["packages/*"], a member app depending on axios@0.21.1, and a Berry lockfile with the app@workspace:packages/app entry.
pinnedYarnMajor(lockfilePath) and yarnLockfileMetadataVersion(lockfilePath) in src/parsers/yarn-lock.ts supply the signals above; when they say Yarn 2 the plan builder records the within-range finding as skipped (plan.skipped: the reason is in the --json and --report skipped lists, and the terminal shows the usual no-fix marker) and creates no refresh target, so --fix never spawns yarn up -R on Yarn 2.
Changelog entry under Unreleased / Fixed.
Tests
tests/fixture-scan.test.ts: on examples/yarn-berry a within-range refresh for follow-redirects expects yarn up -R follow-redirects and plan.yarnBerry === true; on examples/yarn-berry-workspace the member is read from buildYarnWorkspaceMap (asserted to be ["app"]) and the command expected is yarn workspace app up -R follow-redirects; the existing yarn-within-range test keeps yarn upgrade js-cookie and now also asserts plan.yarnBerry === false. Without the Berry branch the first of these fails with "Expected: yarn up -R follow-redirects, Received: yarn upgrade follow-redirects".
Yarn 2: tests copy examples/yarn-berry to a temp dir and vary the pins, the lockfile version and the line endings. Skipped with the reason, and --fix spawns nothing: packageManager: yarn@2.4.3; yarnPath with a trailing comment; yarnPath 2 next to packageManager: yarn@4 (yarnPath wins); no pin with a version-4 lockfile, LF and CRLF; no pin and no lockfile version (reason says the version is unknown, and a separate test checks the unknown and old-lockfile reasons are distinct). Command printed: ignorePath: true next to a Yarn 2 yarnPath and packageManager: yarn@4; packageManager: yarn@3.0.2 with a version-4 lockfile; no pin with the version-8 lockfile, LF and CRLF.
tests/fix-runner-apply.test.ts: two tests record the argv --fix spawns for a yarn parent-update target: ["yarn","upgrade","follow-redirects"] on Classic; ["yarn","up","-R","follow-redirects"] and ["yarn","workspace","app","up","-R","follow-redirects"] on Berry.
Checks

The live scan of the workspace example prints the root-level form. That is how within-range refreshes are scoped today for every package manager, not something this PR changes: examples/npm-workspace-transitive prints npm update minimist at the root too, because collectWorkspacesFromAllPaths in npm-transitive-resolution.ts only reads three-segment paths and a workspace path has four (project › app › axios › follow-redirects). yarn up -R at the root refreshes the whole project, so the printed command runs. The member-scoped form is what the plan prints once a member is known, covered by the unit test; making the resolver read workspace paths is a separate change that would affect npm, pnpm and bun alike.

Summary
Summary by CodeRabbit
Bug Fixes
Fixed within-range package update commands for Yarn Berry projects. Updates now use yarn up -R, including workspace-scoped updates for the workspace that declares the package.
Yarn Classic projects continue to use yarn upgrade; suggested and applied fixes use the appropriate command for each Yarn version.
Yarn 2 projects are skipped for these updates because the required recursive command is available only in Yarn 3 and newer.
Unpinned projects with older or unreadable lockfile versions are also skipped, with the reason reported.
Yarn Berry fix plans and apply operations now use yarn up -R, including workspace-scoped commands. Unsupported Yarn versions skip these recursive refreshes. Yarn Classic continues to use yarn upgrade.
The planner detects Berry lockfiles and pinned Yarn versions. It selects yarn up -R for supported Berry refreshes and skips Yarn 2 or unknown and older unpinned lockfile versions. Tests cover Classic, Berry, version detection, and workspace plans. The changelog records the command behavior.
The apply path uses the plan’s Berry flag to select yarn up -R or yarn upgrade, including workspace commands. Tests cover Classic, Berry root, and Berry workspace commands.
OWASP/cve-lite-cli#1539: Both changes select Berry-compatible commands for within-range fixes while retaining Classic behavior.
OWASP/cve-lite-cli#1532: That PR improves transitive finding paths and workspace attribution used by these Berry refresh commands.

The PR adds Classic and Berry tests and reports a runnable Yarn 4 example. But src/remediation/fix-commands.ts:410-422 now skips Yarn 2 and some unpinned projects where the base emitted a command. The workspace scan also retains a pre-existing scope gap: src/scanner.ts:628,760-765 does not supply a Yarn workspace map, while the new workspace test supplies members manually.

I recommend changing Fixes #1537 to Refs #1537. Alternatively, provide a working Yarn 2 refresh path and make real Berry workspace scans produce the member-scoped command, with scan coverage.

Preserve the detected Yarn flavor for fix commands
If the planner cannot reread a Berry lockfile, users can receive yarn upgrade, which Yarn Modern does not support. I’d carry the flavor from the initial parse or report the classification failure instead of assuming Classic.
As per path instructions, flag “fix commands or upgrade targets that a developer could not actually run.”

Kept the Classic default, and the flavour now travels on the plan: buildSuggestedFixCommandPlan reads the lockfile once, stores plan.yarnBerry, and the --fix runner uses that instead of re-detecting. An unreadable file at this point is not a state a scan with findings can be in: this same process parsed that path moments earlier to produce the packages the plan is built from, and buildYarnWorkspaceMap rereads it the same way two lines above. Failing the whole plan for a read error that cannot happen would cost every Classic user their commands for nothing.

@RClaudiuM Users now get the same Yarn flavor in the plan and the --fix runner. I confirmed that the runner uses plan.yarnBerry.
The original edge case remains possible if the lockfile becomes unreadable after parsing but before plan creation. Also, buildYarnWorkspaceMap reads package manifests, not the lockfile. I understand your decision to accept that unlikely risk, and I won’t press for a change.
Use a recursive refresh for transitive Berry dependencies.
When a vulnerable package is absent from all workspace manifests, the suggested yarn up command fails and leaves it unchanged. I recommend yarn up -R <pkg> for Yarn 4, with a compatible refresh strategy for other supported Berry versions.
As per path instructions, flag “fix commands or upgrade targets that a developer could not actually run, or that do not move the vulnerable package.”

Switched to yarn up -R, after checking on Yarn 4.14.1 against the examples/yarn-berry lockfile: yarn up follow-redirects exits with "Pattern follow-redirects doesn't match any packages referenced by any workspace" and changes nothing, while yarn up -R follow-redirects moves the lock entry from 1.14.0 to 1.16.2 and leaves package.json alone. -R exists since the first Berry release, so no per-version strategy is needed.

@RClaudiuM Thanks for testing this. Your change lets Yarn 4.14.1 users refresh the transitive package in that example.
There is still a Yarn 2 compatibility gap. The Yarn 3.0.0 changelog says it introduced yarn up -R. The planner treats Yarn 2 as Berry, so it will also emit this unsupported flag for Yarn 2.
Could we provide a Yarn 2-compatible path or tell users to upgrade Yarn, and add coverage for the plan and --fix?
Separately, the last saved pre-merge gate is blocking because it flags the fixture’s new axios runtime dependency. The saved checks also call for a real Berry workspace scan. Please rerun the checks on the current revision.

Handled in b64760c. -R is 3.0.0+ as you say, so a project that pins Yarn 2 (packageManager: yarn@2.x in the root package.json, or yarnPath: .yarn/releases/yarn-2.x.cjs in .yarnrc.yml, read by pinnedYarnMajor()) now gets the within-range finding in the skipped list with the reason and the Yarn 3+ steps, and no refresh target, so neither the plan nor --fix emits yarn up -R on Yarn 2. A Berry project with no pin is treated as Yarn 3 or newer; the lockfile itself does not record the Yarn version. Two tests cover both pin forms (plan has no command, no target, one skipped entry naming Yarn 3 or newer); --fix has nothing to run because no target exists.
The reason will be displayed to describe this comment to others. Learn more.
@RClaudiuM Thanks. Pinned Yarn 2 users now get upgrade guidance instead of an unsupported command.
Unpinned Yarn 2 users still receive yarn up -R, which Yarn 2 cannot run. Could you avoid assuming an unknown version is Yarn 3+ and add coverage for the plan and --fix? Issue #1537 also calls for a runnable Yarn 2 remediation unless its requirements change.

Unpinned projects are no longer assumed to be Yarn 3+ (0c8bcc2). With no yarnPath and no packageManager, the lockfile's __metadata.version decides: version 4 was written by Yarn 2.x and 3.0 (LOCKFILE_VERSION in yarnpkg/berry Project.ts is 4 at tags 2.4.3 and 3.0.0, 5 at 3.1.0, 6 at 3.6.4, 8 at 4.0.0), so an unpinned version-4 lockfile gets the skipped entry, and a version-5+ lockfile proves Yarn 3.1+ and gets yarn up -R. Covered for the plan (version 4 unpinned → skipped; version 4 with packageManager: yarn@3.0.2 → command; version 8 unpinned → command); --fix has no target to run in the skipped cases, which the existing runner tests already model by only spawning for targets. On the issue scope: Yarn 2 has no command at all that refreshes a transitive package (up without -R only accepts packages a workspace declares), so no PR can print a runnable Yarn 2 refresh; the closest runnable guidance is what the skipped reason now says.
@RClaudiuM Thanks. The change skips the refresh for an unpinned version-4 lockfile and gives users Yarn upgrade guidance. I agree that upgrading Yarn is a reasonable fallback for Yarn 2.
I still see two cases where the planner can emit yarn up -R without establishing that the active Yarn supports it:
A newer lockfile does not prove which Yarn binary is running. Yarn 2.4.3’s source accepts metadata versions greater than or equal to 4 when reading compatible lockfiles.
With CRLF line endings, the metadata regex in src/parsers/yarn-lock.ts Line 173 returns null. The planner then defaults to 99, even for a version-4 lockfile.
I recommend checking the active Yarn version, or treating it as unknown when it cannot be established. Please add plan and --fix coverage for these cases. I inspected the code but did not run the tests.
Separately, the last saved pre-merge gate is blocking on the fixture’s new axios dependency. The saved checks also flag the Yarn 2 and unpinned Yarn 3.0 scope, and call for a real Berry workspace scan. Please update #1537 to reflect any accepted limitations and rerun the checks on the current revision.
The reason will be displayed to describe this comment to others. Learn more.
Both points are addressed in ca83b17, one with a code change and one with an explanation.
CRLF: fixed. The regex accepts \r\n. An unpinned project whose lockfile version can't be read is now skipped with an "unknown Yarn version" reason instead of defaulting to 99. Details and tests are in the other thread.
A v5+ lockfile doesn't prove the binary: you're right that it doesn't, and the PR body now says so. I'm keeping the inference instead of treating every unpinned project as unknown, for three reasons:
A version-5+ lockfile was last written by Yarn 3.1 or newer. For yarn to run Yarn 2 in that project afterwards, someone has to have switched to an older global binary without pinning it.
The scanner can't read anything that says which binary is on PATH. Running yarn --version during a read-only scan would execute the project's package manager, and through Corepack it could download one. Treating all unpinned projects as unknown would drop a working command for every unpinned Yarn 3.1+ or 4 project just to cover that downgrade.
When the inference is wrong, the failure is loud and changes nothing. I checked this on Yarn 2.4.3 with a copy of examples/yarn-berry: yarn up -R follow-redirects exits 1 with Unknown Syntax Error: Unsupported option name ("-R") and leaves yarn.lock byte-identical. --fix then throws on the non-zero exit instead of counting the fix as applied.
Coverage: every skipped case (pinned Yarn 2 in all three forms, unpinned v4 with LF and with CRLF, unpinned with no lockfile version) now asserts the plan and then runs it through applyFixesIfRequested with a recording runner, which spawns nothing. Unpinned v8 with LF and with CRLF asserts yarn up -R follow-redirects.
Scope: the PR body now says Refs #1537 and lists the accepted limitations: Yarn 2 has no runnable transitive refresh, unpinned v4 or unknown-version lockfiles are skipped with guidance, and workspace scoping is tracked in #1548. I've left the issue text itself to the maintainers.
@RClaudiuM Thanks. Unpinned projects with unreadable metadata now get guidance instead of an unsupported refresh command. I checked the parser and planner, and the tests cover the CRLF and skipped cases. I did not run them.
I understand your decision to keep the version-5+ inference. If the active binary is Yarn 2, the command can still fail, but your test shows that it fails without changing the lockfile. Thanks for documenting that limitation and tracking workspace scope in #1548.
Separately, the last saved pre-merge gate is blocking on the fixture’s new axios dependency. Please rerun the checks on the current revision and address that failure if it remains. I have not verified the current gate status.

- Around line 184-185: Update the yarnPath detection so a Yarn 2 release pin
with a trailing inline comment is recognized, allowing the planner to avoid
offering the unsupported `yarn up -R` command. Add a plan test covering
`yarnPath: .yarn/releases/yarn-2.4.3.cjs # pinned` without a `packageManager`
pin.
- Around line 177-178: Update Yarn version detection around the packageManager
pin to resolve the effective version from an active yarnPath before falling back
to packageManager, while honoring ignorePath; ensure command planning uses that
effective version. Add a regression test for a Yarn 3 or 4 packageManager pin
conflicting with a Yarn 2 yarnPath, including the ignorePath behavior.

A Yarn refresh target can exclude another parent’s range when its registry manifest is unavailable. I suggest reporting the result as unverified when a parent’s range cannot be checked, rather than issuing a within-range fix.

The Yarn upgrade builder had no Berry branch, so a Berry project got `yarn upgrade <pkg>`, which Berry does not have. The plan builder now reads the lockfile once with isYarnBerryLockfile() and the builder prints `yarn up <pkg>` (and `yarn workspace <name> up <pkg>` for members) on Berry. Classic projects keep `yarn upgrade`.
)
On Yarn 4.14 `yarn up <pkg>` refuses a package no workspace declares ("Pattern follow-redirects doesn't match any packages referenced by any workspace"), while `yarn up -R <pkg>` moves the transitive entry (1.14.0 -> 1.16.2) and leaves package.json alone. The plan now carries yarnBerry so the --fix runner spawns the same verbs as the printed command. A Berry workspace example (examples/yarn-berry-workspace) backs the member-scoped test.
…Yarn 2 (OWASP#1537)
`yarn up -R` arrived in Yarn 3.0. A project whose root package.json packageManager or .yarnrc.yml yarnPath pins Yarn 2 now gets the within-range finding in the skipped list with the reason and the Yarn 3+ steps, instead of a command Yarn 2 rejects. Projects with no pin are treated as Yarn 3 or newer.
…ckfile when unpinned (OWASP#1537)
An active yarnPath is what `yarn` runs, so it now wins over packageManager unless ignorePath is set, and .yarnrc.yml is parsed as YAML so a trailing comment on the pin no longer hides it. Without any pin, a Berry lockfile at __metadata version 4 (written by Yarn 2.x and 3.0; 3.1 moved to 5) counts as Yarn 2, so an unpinned Yarn 2 project gets the skipped entry instead of `yarn up -R`.
…Yarn version is unknown (OWASP#1537)
The __metadata version regex only matched LF line endings, so a CRLF
lockfile read as having no version and the planner assumed a modern
Yarn. The regex now accepts CRLF, and an unpinned project whose
lockfile version cannot be read gets the refresh in the skipped list
with a reason that says the version is unknown, instead of a
`yarn up -R` that Yarn 2 rejects.

fix(yarn): use yarn up -R for within-range fixes on yarn berry
fix: use yarn up -R for within-range fixes on yarn berry
Nov 7, 2026
Update for the review from 2026-11-06 19:29. The branch is rebased on main and has one new commit, ca83b17. The inline items are answered in their threads. This comment covers the outside-diff item and the pre-merge checks.
Outside diff, fix-commands.ts:431 (unverified parent ranges): I agree this is a real gap, but it's pre-existing and not in the Yarn code this PR changes, so I haven't changed it here.
The within-range decision is made in resolveTransitiveRemediationViaRegistry in src/remediation/npm-transitive-resolution.ts. It merges every parent's range through registryRangesFromEveryParent/registryParentRanges, which came in with fix(remediation): require every parent to accept a within-range update target #1458. A parent whose manifest the registry can't return is dropped from that list, not reported as unverified.
That resolver is shared by pnpm, Yarn and Bun. This PR only changes which verb the Yarn planner prints for a remediation the resolver has already returned. Fixing the resolver here would change pnpm and Bun output too.
For Yarn specifically, yarn up -R resolves every descriptor against its own declared range. So it never forces a version outside a parent's range. The risk is that the "can be refreshed to X+" claim is too optimistic for a copy held through the unverified parent.
@coderabbitai could you open a follow-up issue for reporting a within-range target as unverified when any parent's manifest is unavailable? Could you also open a second one for the Berry lockfile parser? It splits blocks on \n\n, so a CRLF lockfile loses its transitive packages (found while testing the CRLF metadata fix).
Pre-merge checks:
Title: now fix: use yarn up -R for within-range fixes on yarn berry, the type: short description form from .coderabbit.yaml.
Linked issue / closes keyword: the body now says Refs #1537 instead of Fixes. It also has an "Accepted limitations" section:
Yarn 2 has no command that refreshes a transitive package, so it gets the skipped entry with the Yarn 3+ steps.
An unpinned project with a v4 lockfile or no readable lockfile version is skipped with guidance.
No new runtime dependency: the root package.json and package-lock.json are unchanged. The axios entry is in an intentionally vulnerable fixture under examples/. Details are in the test thread.
Checks on ca83b17:npm run lint:tests passes and npm run build is clean. node scripts/typecheck-changed-tests.mjs upstream/main reports the changed test files clean with no new errors. After advisories sync, the full npm test run gives 221 suites: 3331 passed, 2 skipped.

fix: use yarn up -R for within-range fixes on yarn berry
fix: print a runnable within-range refresh command on yarn berry
Nov 7, 2026
On the pre-merge checks from the re-review of ca83b17. That review didn't post any new code findings.
Title: the -R broke the lowercase rule. It's now fix: print a runnable within-range refresh command on yarn berry, and the exact command stays in the description.
Closes keyword: the body already says Refs #1537, not Fixes, so this check seems to be reading the old description.
Linked issue: the Yarn 2 and unpinned-v4 skips are listed under "Accepted limitations" in the body. Yarn 2 has no command that can refresh a transitive package, so no automated test can exercise a runnable one. Updating fix(yarn): Berry fix commands use yarn upgrade, which Berry does not support #1537 itself is up to the maintainers.
No new runtime dependency: I'm leaving this as is. The check's own text is about package.json gaining an entry, and the root manifest and lockfile are unchanged. The new axios entry belongs to the examples/yarn-berry-workspace fixture, which was added because an earlier review on this PR asked for a fixture with a real named member whose refresh is verified on Yarn. The other Berry workspace examples are large real-world snapshots. If a maintainer would rather have no new fixture, I can point the unit test at one of those and drop it.
For best results, initiate chat on the files or code changes.

@RClaudiuM Users can receive an overoptimistic refresh target when a parent range is unavailable, and CRLF Berry lockfiles can lose packages during parsing.
I couldn’t open the follow-up issues. GitHub reports that you have read access to this repository, but issue creation requires verified write access. A maintainer with write access can file the drafts below, or you can ask me to retry after your access changes.
Follow-up issue drafts
Report unverified parent ranges for within-range remediation
src/remediation/npm-transitive-resolution.ts filters out null ranges returned by registryParentRanges. A target can therefore appear to be within range even when a parent’s manifest is unavailable.
Preserve the unverified state and report it instead of presenting the target as verified for every parent. Add tests for unavailable parent manifests and for fully verified ranges. Cover both the direct and deep-chain resolution paths. This resolver is shared across package managers.
Parse CRLF Yarn Berry lockfiles without losing packages
loadFromYarnBerryLock in src/parsers/yarn-lock.ts splits blocks on LF-only blank lines. CRLF lockfiles can therefore lose transitive packages and dependency paths.
Support CRLF and LF lockfiles consistently. Add tests that compare parsed packages and transitive paths for equivalent lockfiles with both line endings.
I confirmed that the current title follows the configured form and the body uses Refs #1537. The root manifest and lockfile are unchanged. GitHub shows successful build and CodeQL checks; I did not run the reported tests.
The last saved pre-merge gate is still blocking because the fixture adds axios under dependencies. The configured check does not state a fixture exception and requires maintainer sign-off for new runtime packages. Please get a maintainer decision on the fixture and rerun the pre-merge checks before merging. The saved linked-issue warning also needs a fresh assessment; using Refs does not itself complete #1537.

# Contributing to CVE Lite CLI
## Code standards
- CI also type-checks the test tree against your branch point. Test files your pull request adds or changes must have no type errors, and no other file may gain a type error, so a source change that breaks an unchanged test fails too. Errors that already exist on `main` are the backlog and do not fail. The gate matches errors by file, error code and message, so a source change that alters a backlog error's message counts as a new error. It only sees committed changes, so commit before running it (it compares against the merge base, so a branch that is behind `main` still sees only its own changes). Fix a type error rather than silencing it: a cast, an `any` or a widened type removes the check the gate exists for.
Thanks @RClaudiuM, this is careful work. yarn up -R is the right within-range form, the Yarn 3.0 research holds up, and the CRLF and unknown-version handling is thorough. Every mutation I tried against your tests got caught.
The difficulty is that #1539 implements the same fix for #1537 and was opened a few hours earlier, and we give the older of two duplicate PRs the first chance to land. On every tree I tried, the two print the same commands, and they conflict in nearly every file, so only one of them can go in. I've reviewed #1539 and it's close.
So I'm going to hold this one rather than ask you for more work on it. Two of the things you did better are worth carrying over, and I'll ask for them on #1539 with credit to you: reading .yarnrc.yml with the yaml parser we already ship instead of regexes, and skip reasons that give the commands to run. If #1539 stalls, this is the fallback, and I'll come back to it.
Thanks for the thorough review, and that makes sense. Happy for #1539 to go first, and glad the yaml parsing and skip-reason commands are useful there. I'll leave this open as the fallback; if it ends up being needed, I'll rebase it.

Refs #1537
Problem
On a Yarn Berry (v2+) project the within-range fix command read
yarn upgrade <pkg>, which Berry does not have, so the command we print failed when pasted, and--fixspawned the same thing. The Yarn upgrade builder insrc/remediation/fix-commands.tshad no Berry branch, although the scanner already tells Classic and Berry lockfiles apart insrc/parsers/yarn-lock.ts.What Yarn 4 actually accepts
Checked on Yarn 4.14.1 against the
examples/yarn-berrylockfile (follow-redirectsis transitive viaaxios):yarn up follow-redirectsexits withUsage Error: Pattern follow-redirects doesn't match any packages referenced by any workspaceand changes nothing.yarn up -R follow-redirectsmoves the lock entry from 1.14.0 to 1.16.2 and leavespackage.jsonalone, which is exactly the within-range refresh we want.yarn workspace app up -R follow-redirectsworks the same way; without-Rit fails identically.So the Berry form is
yarn up -R <pkg>, andyarn workspace <name> up -R <pkg>for a member. On a copy ofexamples/yarn-berry-workspace(lock pinned atfollow-redirects@1.14.0),yarn workspace app up -R follow-redirectsmoved the entry to 1.16.2.-Rwas added in Yarn 3.0.0 ("yarn upnow supports a new-R,--recursiveflag"). A project on Yarn 2 therefore has no command that refreshes a transitive package, and such a project now gets the finding in the skipped list with the reason and the Yarn 3+ steps (yarn set version stable, thenyarn up -R <pkg>) instead of a command Yarn 2 rejects. Yarn 2 is recognised from, in order:yarnPathin.yarnrc.yml(parsed as YAML, so quotes and trailing comments are fine), which is whatyarnruns, unlessignorePath: true;packageManager: yarn@2.xin the root package.json;__metadata.version(LF or CRLF): 4 was written by Yarn 2.x and 3.0 (LOCKFILE_VERSIONin yarnpkg/berryProject.tsis 4 at tags 2.4.3 and 3.0.0, 5 at 3.1.0, 6 at 3.6.4, 8 at 4.0.0), so an unpinned version-4 lockfile counts as Yarn 2. An unpinned Yarn 3.0 project gets the guidance too; pinning it (packageManager: yarn@3.x) restores the command.__metadata.version, the Yarn version is unknown: the refresh is skipped too, and the reason says the version could not be determined (runyarn up -R <pkg>ifyarn --versionis 3 or newer, otherwiseyarn set version stablefirst) rather than calling the lockfile old.An unpinned project with a version-5+ lockfile gets
yarn up -R. That lockfile was last written by Yarn 3.1 or newer, which is the project's Yarn unless someone has since switched to an older global binary without pinning it. Yarn 2.4.3 does read newer lockfiles, so this is an inference, not proof of the binary; if it is wrong, Yarn 2 rejects the command (Unknown Syntax Error: Unsupported option name ("-R"), exit 1, lockfile untouched) and--fixstops on the non-zero exit.Accepted limitations
yarn upwithout-Ronly accepts packages a workspace declares), so a Yarn 2 project gets the finding in the skipped list with the reason and the Yarn 3+ steps instead of a command. This is why the PR usesRefs, notFixes: fix(yarn): Berry fix commands use yarn upgrade, which Berry does not support #1537 asks for a runnable command on Berry, which Yarn 2 cannot have.yarn up -R <pkg>(which runs and refreshes the whole project) rather than the member-scoped form, because the transitive resolver does not read workspace paths for any package manager. That is tracked in Resolve workspace paths for transitive remediation #1548.Change
