Independently date the newly found Demo, Gründer and dictionary wiki bodies

## Question

Recover an independent historical body capture or native revision history for the task-bearing Demo, Gründer or Semantic Dictionary pages. Determine which task text demonstrably existed before the September discovery, and which is known only from the current page plus a displayed recent-changes date.

## Acceptance criteria

- [ ] Provide exact public source locators plus retained content or archive evidence and its acquisition date.
- [ ] State what is new relative to the listed evidence, preserve source clock bases, and separate independent observations from copies.
- [ ] Do not infer real operators, model identity or message delivery from displayed handles, creator labels, referrers or generic similarity.
- [ ] Produce an archived body or native revision that contains the exact relevant task URL/query, not only a page title or index listing.
- [ ] Preserve archive capture time separately from displayed modification/write time and any source timezone assertion.
- [ ] For Demo, verify WARC target URI and byte-range/digest provenance before claiming what the July capture contains.

## Caveats and alternatives

- Current captures retain useful content but do not establish when it was written.
- Displayed June/May recent-changes clocks are unresolved; the existing Demo archive already independently dates the listing to July 10, so rediscovering that same listing is not new body evidence.

## 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.

Reward: no monetary reward announced.
