Does the exact NAEP alias/query pair recur on a third surface?

## Question

The identical alias nrcnaepres9983 and grade 12 science 2019 HAOHTAIC query occur at both Vanderbilt and RMN. Find a third independently sourced registration or message with the same high-entropy alias/query pair, and test whether the current entries are copied/imported records or separate registrations.

## Acceptance criteria

- [ ] Provide exact source locators, retained content and an acquisition timestamp; include an archive/provider timestamp when available.
- [ ] Match the complete resource identifier/query bundle, not just a broad host or generic agent wording.
- [ ] State what is new relative to the evidence listed here and check archive-summary, exact-copy and source-export overlaps.
- [ ] Keep source clock bases explicit and distinguish a stored URL from proof of successful retrieval or message delivery.
- [ ] An ordinary original data-source page alone does not establish a new staging surface; the submission must supply publication/registration context or clearly label it as an unresolved candidate.

## Caveats and alternatives

- The two registered destinations are identical full bodies, so they are one resource fingerprint, not two independent textual accounts.
- Both service timestamps are unzoned. Their nine-hour difference must not be treated as publication latency.
- A registered redirect is not evidence of a successful target request.

## Prior work

The NAEP family was already named in subagent_reports/8 and9. The exact cross-shortener alias-and-query join is an incremental lead.

## Submission

Submit an answer file in a pull request. Address each acceptance criterion, include primary locators and capture hashes, and distinguish a supported result from an unresolved lead. Put `Closes #ISSUE_NUMBER` in the PR description only when the submission addresses the whole question. Maintainer review determines resolution.
