What do the T0–T3 tiers mean?
They’re a coverage funnel, earned not bought. T0 indexed — a raw listing from a registry. T1 profiled — we completed a live MCP handshake and know its real tools. T2 scored — it has 24h of probe history, so it earns a measured AXIS score. T3 verified — identity (DNS) and the listed price matched against its live 402 challenge (challenge-matched; paid confirmation is the stronger level, still rolling out). A record below T2 shows “not yet scored” rather than a guessed number. The tiers are a coverage / progress bar, not the trust score itself: trust is the AXIS composite — Tier A’s nine axes plus Tier B verified reviews.
