LOCAL-FIRST / TAXON HOME

Make the messy
legible.

Cold Index is primarily the home of Taxon — browser-local event taxonomy cleanup. Utmend and Macrow sit alongside for URL and macro hygiene.

01FLAGSHIP · EVENT TAXONOMY

Taxon

Same event. Three names.
Kill the drift.

Browser-local event taxonomy cleaner. What the app does:

Amplitude / Mixpanel / Heap — CSV dialects + honest detection chip
Properties + merge confidence — canonical key merge · TYPE pick · shared props on clusters
Cluster review — sticky keep-separate · accept canonical · click shared/differ for examples · filters (near-dups only / low overlap / high volume) · Properties Accept → pack
Maps, packs, prior-schema diff — taxon-map.json · wiki taxon-pack.md · schema diff vs prior
Public trial — all features unlocked · local-only
