undefined-ui Merge duplicate pages
A merge is irreversible in the way that matters: afterwards you cannot tell which claim came from which page. Two ideas that look identical from their summaries are often a general case and a specific one.
Core rule
Never merge unprompted. Propose, wait for approval, then follow the procedure exactly.
Workflow
- Pick the survivor by canonical name, not by which page is longer.
- Merge content. Every distinct claim survives with its source. Overlapping claims collapse; differing ones both stay, following the contradiction rules.
- Merge aliases, including the dead page's title as an alias on the survivor. This is what keeps old links and the user's memory working.
- Redirect inbound links to the survivor. Check every backlink.
- Delete the old page, or leave a stub only if it was linked from outside the vault.
- Record in
log.md: both names, the date, and why.
Output format
Merged: [[old]] -> [[survivor]]
Claims kept from old page: <n>
Aliases added: <list>
Inbound links redirected: <n>
Conflicts recorded: <none | description>
Calibration
If the two pages disagree about anything factual, that is a signal they may not be duplicates. Surface the disagreement and ask before proceeding.
Never merge a page marked maintained_by: human into another without explicit
confirmation naming that page.
