v1.73.0 — Warnings to Zero

First public release of Tropo.

Fixed

• Cleared roughly 1,500 stale validator warnings (2,157 down to 662) by classifying old, immutable historical records as known exemptions instead of recurring noise. No history was rewritten and no real problems were hidden; going-forward checks still fail loudly on any new violation.
