Fixes#1549 by recognizing that < and <= specify upper-bound ceilings rather than minimum floors in OA009 (src/overrides/detectors/oa009-stale-floor.ts).
Previously, allParentsMeetFloor used coerceVersion(parent.declaredValue) which stripped leading < and <=, treating <2.0.0 or <=1.5.0 as having floors of 2.0.0 or 1.5.0. When an override specified e.g. js-yaml: ">=1.0.0", compareVersions("2.0.0", "1.0.0") >= 0 evaluated to true, falsely reporting the override as redundant and emitting an RFC 6902 remove patch to delete it.
Changes
Introduced extractParentFloor in src/overrides/detectors/oa009-stale-floor.ts which returns null for pure upper-bound ranges (< or <=) and correctly extracts the lower floor from compound ranges (e.g. >=1.2.0 <2.0.0).
Added unit tests in tests/overrides/detectors/oa009.test.ts covering:
Parent declarations with <X.Y.Z and <=X.Y.Z for both >= and ^ override floors.
Compound ranges with lower bounds meeting or failing the floor.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Improved OA009 findings for parent version ranges. Upper-bound-only constraints no longer produce findings, while compound ranges are evaluated using their lower bound.
Ranges such as 1.x and spaced >= constraints produce findings when their lower bound meets the override floor.
For union ranges, findings are reported only when every alternative meets the floor, preventing findings when any alternative falls below it.
OA009 now checks the minimum version selected by each parent declaration’s range against an override floor. Upper-bound-only ranges do not satisfy the floor. Tests cover compound, wildcard, spaced comparison, and union ranges.

Summary
Extract and check parent floors src/utils/version.ts, src/overrides/detectors/oa009-stale-floor.ts, tests/overrides/detectors/oa009.test.ts
rangeMinVersion returns the minimum version selected by a range, or null when it cannot determine one. OA009 uses this result to check parent declarations against an override floor. Tests cover upper-bound-only, compound, wildcard, spaced comparison, and union ranges.
OWASP/cve-lite-cli#1565: Updates the same OA009 test context with admitted-version and admitted-vulnerability maps.
Merge Risk: Moderate · previous review d15f1
The change fixes the reported < and <= parent cases. In edge cases involving prerelease versions or caret overrides, OA009 can still suggest removing an override that is needed. Resolve or explicitly accept these before merging.

Explanation
Users are protected from OA009 removing overrides because of upper-bound parent ranges. The detector now uses rangeMinVersion in src/overrides/detectors/oa009-stale-floor.ts. The helper uses semver.minVersion with loose parsing, so < and <= ranges produce a minimum below the tested override floors, while compound ranges retain their lower bound. Tests in tests/overrides/detectors/oa009.test.ts cover upper bounds against >= and ^ floors, compound ranges above and below the floor, and unions. This meets the coding requirements in [#1549].
Full details: Closes Keyword Matches Scope
Explanation
Users can still receive a removal patch for an upper-bound parent range. Issue #1549 asks OA009 to retain overrides for < and <= parents and to test both >= and ^ overrides. The PR adds those tests, but it does not cover every requested case: for parent <1.0.0 and override ^0.0.0, the new rangeMinVersion returns 0.0.0, so OA009 emits a removal patch. The base code rejected this case because the parent major was 1.
Resolution
I recommend rejecting pure upper-bound parent ranges and adding a ^0.0.0 regression test. Otherwise, change Closes #1549 to Refs #1549.

- Around line 19-46: Update extractParentFloor to account for the complete
parent range before returning a floor; do not derive a removal recommendation
from only one alternative in a union. Skip unions when their alternatives cannot
be proven safe, while preserving recommendations only when all alternatives
establish that removing the floor is safe.
- Around line 38-46: Update the OA009 parent-range comparison to compare the
complete semver ranges rather than coercing each range to a single floor
version. Preserve prerelease semantics so an admitted prerelease such as
1.0.0-beta prevents recommending removal of an override that excludes it.

Thanks @muntasir-396, the case from #1549 is fixed: a parent declaring <2.0.0 no longer makes OA009 recommend removing a >=1.0.0 floor, and the same goes for <=1.5.0, <2, <2.x and the union cases. The override examples all give the same output as main.
The trouble is the hand-written range reading. With a space after the operator, < 2.0.0 or <= 1.5.0, the range splits into < and 2.0.0, the "all upper bounds" check fails, and OA009 still says to remove the floor. That's the direction that matters, since it tells someone to drop a security floor. I built the #1549 repro as a small project and cve-lite overrides reports it with the spaced form exactly as on main. It also goes quiet on two ranges that should still fire: >= 1.2.0 (spaced) and 1.x.
…floor
Upper-bound constraints (< and <=) specify ceilings rather than minimum floors. Previously, coerceVersion stripped < and <=, treating ranges like <2.0.0 as having a floor of 2.0.0 and falsely flagging valid overrides for removal. ClosesOWASP#1549
If OA009 ignores a later union alternative or drops a parent prerelease tag, it can recommend removing a needed override. I recommend tests for >=5.0.0 || <1.0.0 against >=0.5.0 and >=1.0.0-alpha against >=1.0.0. Both should produce no finding.

Thanks @muntasir-396, this is ready. Moving to semver.minVersion through a helper next to isValidRange fixed the spaced-operator and 1.x cases I raised along with the original bug. On real override projects, a parent declaring <2.0.0, <= 1.5.0 or a <1.0.0 || >=5.0.0 union no longer gets a false OA009, while ^1.2.0, >= 1.2.0, 1.x and hyphen ranges still fire as they should. Merged with current main the suite passes and it builds.
Two optional extras if you're back in the file: a test with a >=1.0.0-beta parent against a >=1.0.0 override (that's a real behaviour change with no test yet), and a couple of direct tests for rangeMinVersion next to the isValidRange ones. CodeRabbit's 0.0.0-beta thread only applies to a floor of exactly 0.0.0, so a short reply is enough there, no code change.
Approved. I merge these one at a time rather than in a batch, so it will land shortly.

Keep caret overrides that still restrict the parent range.
With override ^0.0.0 and parent <2.0.0, OA009 can offer to remove the override. The parent admits versions outside the override, so removal can change dependency resolution.
I would check full parent-range containment for caret overrides in the OA009 guard, while retaining the existing >= floor behavior.
