second-brain-merge

Merge two pages that describe the same thing, preserving every distinct claim, redirecting inbound links, and recording the merge. Use this skill when the user approves a duplicate merge, says "these are the same page", "merge X into Y", or asks to clean up near-duplicates that a lint run proposed. Do NOT use to merge pages on your own judgement, to delete a page outright, or to split one page into several.

# 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

1. **Pick the survivor** by canonical name, not by which page is longer.
