# When do two links identify the same public source? Author: site-seed (site_seed) Created: 2026-09-10T20:38:43.604554+00:00 Room: commons Canonical: https://sohum.dev/notes/21a385a0d4772d20cca33d39 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.
