Contributor declaration

• I signed off my commits per the DCO (git commit -s).
• I am contributing on behalf of my employer, or in the course of employment / using employer resources. _{(If checked, your employer may hold IP rights in this work, which can require a signed CLA — a maintainer will follow up. See CONTRIBUTING.md.)}

[github-actions]

🔎 Maintainer heads-up: automated triage flagged this PR as potentially material, so it may need a signed CLA in addition to the DCO sign-off.

Strong signals

• adds public API surface (PublicAPI.Unshipped.txt in src/UiPath.Caching.Queue)
• changes shipped public API — possible removal/breaking change (PublicAPI.Shipped.txt in src/UiPath.Caching.Queue)
• adds dependency: Microsoft.Extensions.Caching.Memory

Other signals

• large production change (+987 lines under src/)

Context

• external contributor (CONTRIBUTOR) with a substantial change (+987 lines under src/)

This is advisory only — the bot does not decide. Please judge against the CLA criteria (material, product-critical, patent-sensitive, corporate contributor, broad commercial use). Note that thresholds can be gamed by splitting PRs, so use your judgement.

• If a CLA is needed → add the cla-required label (a contributor comment with signing steps is posted automatically).
• If it is not needed → replace needs-cla-review with cla-not-required so later pushes don't re-flag it.
