fix(remediation): flag parent upgrades that a direct dependency would undo - #1470
When a vulnerable transitive package cannot move within its parents' ranges, we recommend upgrading one parent. That upgrade only moves the copy for that parent. If a package the project declares directly also holds the copy and its range refuses the fixed version, the vulnerable copy stays installed and the command we print changes nothing.
The scanner now finds those packages and records them on the finding. A blocked finding gets no runnable command, no longer counts as covered, cannot borrow a sibling finding's command for the same parent, and says why: "Upgrading @eslint/eslintrc to 3.3.6 alone leaves js-yaml@4.1.1 installed: lerna@9.0.7 requires 4.1.1. Those dependencies need upgrading too." The same list is in the JSON as parentUpgradeBlockers. Both the npm route and the pnpm, Yarn and Bun route are covered.
Only direct dependencies count, identified by a recorded path straight from the project or from a workspace member. A transitive holder is left out on purpose: on examples/nest, upgrading @nestjs/graphql also moves the graphql-tools packages that hold @graphql-tools/utils@11.0.0, so naming them would have claimed a block that does not exist.
Measured across 10 npm, pnpm, Yarn and Bun example projects: 7 findings flagged (nest 1, dyad 2, lit 2, analog 2). For six of the seven, the old command was applied to a copy of the lockfile with npm or pnpm and the vulnerable copy was still installed afterwards (lit's serialize-javascript case run without its workspace flags, which our example lacks); the seventh, lit's ip, could not be run for the same reason. The controls and the graphql case resolve. No other finding's output changed, apart from one merged command in analog dropping from @vitest/browser-playwright 4.1.12 to the 4.1.10 its own finding needs, because the blocked sibling no longer contributes to it.
Not covered here: a direct dependency whose range accepts the fix can still keep the old copy, because npm does not move a dependency that is already satisfied, and packages held only through peer dependencies are not checked.
… from removing the vulnerable copy
A recommended parent upgrade moves the vulnerable copy for that parent only.
When a package the project declares directly also holds the copy and its range
refuses the first safe version, the copy stays installed. Record those packages
on the finding. Transitive holders are left out, since npm and pnpm usually
re-resolve them along with the upgraded parent.
A blocked finding moves to the skipped list with the reason, gets no runnable
command, no longer counts as covered, and cannot borrow a sibling finding's
command for the same parent.

Summary
Summary by CodeRabbit
New Features
Upgrade recommendations now identify direct dependencies that prevent a parent upgrade, including the affected package and required version range.
Bug Fixes
Blocked upgrades are no longer presented as available fixes or used to suggest a remediation command. Reports now explain the blocker instead of implying the upgrade can resolve the finding.
Findings no longer borrow a suggested fix from another finding when their own parent upgrade is blocked.
The scanner now identifies direct dependencies that block a recommended parent upgrade. Fix planning withholds commands for blocked findings, and reports explain the blockers. The scanner also changes cached advisory and OSV detail handling.
A new blocker type and detection function check npm graph holders or published parent ranges. Tests cover direct and workspace dependencies, exclusions, and registry-backed ranges.
Attach blockers during scanning src/scanner.ts, tests/scanner-parent-upgrade-blockers.test.ts
The scanner checks recommended parent upgrades against dependency ranges and workspace members. Tests check that a rejecting Lerna range blocks the command, while an accepting range does not. Scanner detail reads also change when noCache is enabled; cached npm advisories restore full details, and online OSV detail requests exclude IDs prefixed NPM-.
Exclude blocked upgrades from fix plans src/remediation/fix-commands.ts, tests/remediation/fix-commands-blocked-parent-upgrade.test.ts
Fix planning skips blocked findings, prevents them from matching shared upgrade targets, and formats a reason that lists the blockers. Tests check that a blocked finding has no suggested command, including when a sibling finding has one.
Show blocker details in output src/output/formatters.ts, src/output/html-reporter.ts, src/output/printers.ts
Recommended-action summaries and compact output show the blocker reason. Serialized findings include parentUpgradeBlockers, and HTML reports do not count blocked recommendations as available fixes.
OWASP/cve-lite-cli#1442: It provides the shared range evaluation used to identify dependencies that reject the proposed child version.
OWASP/cve-lite-cli#1458: It checks whether all parents accept a within-range target; this change checks holders for a recommended parent upgrade.
OWASP/cve-lite-cli#1450: It suppresses parent remediation for npm-alias paths, another case of transitive parent remediation.

Explanation
Issue #1457 requires the Nest finding to identify the additional parent or state that upgrading @eslint/eslintrc alone leaves js-yaml@4.1.1 installed. The implementation records direct project and workspace blockers in parentUpgradeBlockers, suppresses commands for blocked findings, prevents sibling command reuse, and formats the blocker reason. The scanner test covers lerna@9.0.7 and the formatter output states that the vulnerable copy remains installed. The tests also cover the npm and registry-backed routes, direct-dependency filtering, and workspace members.

Explanation
The PR uses Closes #1457. The issue requires the NestJS case to identify the blocking parent, or clearly state that upgrading @eslint/eslintrc alone leaves js-yaml@4.1.1 installed. The PR records lerna@9.0.7 as a blocker, suppresses the runnable command and coverage, and reports that the dependencies need upgrading too. The end-to-end test asserts the blocker and no command, while the accepting-range control preserves the parent-upgrade command. Formatter and fix-plan tests also verify the required explanation.
Full details: Title check
Explanation
The title accurately describes the change and uses lowercase text without a trailing period, but fix(remediation): does not match the required type: short description form because the type must be exactly one allowed value.
Resolution
Change the title to fix: flag parent upgrades that a direct dependency would undo.

Explanation
The blocker discovery, remediation suppression, output changes, JSON field, and focused tests support #1457. The whole-PR summary also lists unrelated scanner changes to noCache reads, cached npm advisory restoration, and OSV detail filtering for NPM- IDs. The summary provides no connection between those cache and OSV changes and parent-upgrade blockers.
Resolution
Remove the unrelated cache and OSV behavior changes from this pull request, or move them to a separate pull request. Keep only those changes if code evidence shows that the blocker implementation requires them.

Review comments at @src/remediation/registry-parent-ranges.ts:
- Around line 12-24: Update the parent packument lookup in the graph-based range
resolution to throw when fetchPackument returns null instead of treating the
parent’s dependency range as absent. Preserve the existing manifest and range
lookup when a packument is available so the scanner can clear remediation and
continue without publishing an unsafe command.
Review comments at @tests/scanner-parent-upgrade-blockers.test.ts:
- Line 19: Give the queryNpmAdvisoryGaps and resolveChainFix Jest mocks explicit
function return types so their mockResolvedValue calls accept the intended
resolved values and pass the CI type-check; leave the other mock unchanged.
