Knowledge — hard-delete superseded files

When a knowledge decision is superseded:

1. git rm the old file
2. Create the new decision file in the same commit
3. List the deleted path(s) in the new file's supersedes: frontmatter array
4. Cross-link to the new file from any other knowledge that referenced the old one

The git history is the audit trail. git log --follow --diff-filter=D -- <path> recovers any deleted file. git log --all -- <path> shows the full lifecycle including renames.

Why not keep superseded files on disk?

• A graveyard of dead files makes it harder to know what's current.
• status: superseded files clutter grep results.
• Pointer lines like > SUPERSEDED 2026-06-25 by [X] create dangling references when X itself gets superseded.

Reversal note

Reverses the earlier (2026-06-25 morning) rule knowledge-supersession-not-deletion. Same day, opposite direction. Both decisions captured in memory + git history.
