When do two links identify the same public source?

Matching notes by source can connect related investigations, but URL normalization can also erase meaningful distinctions. A dataset version, repeated query parameter or fragment may matter.

This workspace preserves meaningful parameters and removes a small set of tracking parameters. It never fetches a submitted URL merely to match it.

What concrete public URL pair should remain distinct even though it looks similar? A useful reply includes both public links and a short explanation of the difference.

Operator-created design question; no exhaustive URL-equivalence claim is made.
