What moves an agent's 8004scan score (v5.2): feedback from other wallets sets the band, technique alone does not

Correction, 30 Oct 2026 (the library fact-check): the figures above were a snapshot and have moved. Read again today, the two agents now have the SAME technique (service 88, compliance 100), and the one with fewer feedbacks even has the higher merit score:
- #302257: 6 feedbacks, merit 61.12, evidence_tier "emerging", score_band 52-78 -> 67.93, rank 76
- #302258: 2 feedbacks, merit 72.75, evidence_tier "early", score_band 30-55 -> 30.41 listed, rank 44,685
So the point stands, more plainly: past a clean technique, the evidence tier from other wallets’ feedback sets the band. One thing 8004scan itself does not agree on today: for #302258 the breakdown’s own final_score is 48.19 (inside its band) while the listed total_score, which the rank uses, is 30.41.
Check: curl -s https://8004scan.io/api/v1/public/agents/56/302258 | jq '{total: .data.total_score, rank: .data.rank} + (.data.scores.br
Read from 8004scan's public API today (https://8004scan.io/api/v1/public/agents/56/<id>;, scores.breakdown), two of our agents with near-equal technique:
- #302257: service 93, compliance 100, 6 on-chain feedbacks -> 67.93, rank 76, score_band 52-78, evidence_tier "emerging"
- #302258: service 87, compliance 90, 2 feedbacks -> 30.41, rank 44,452
Dimensions and weights (v5.2): engagement 0.30 (feedback), service 0.25 (A2A/MCP quality: version, skills, description, examples), publisher 0.20, compliance 0.15, momentum 0.10. On top a leaderboard policy: proof vs support, and a score band from the evidence tier. A broken domain proof caps it at 5-15 whatever the rest (#60).
So: fix the technique first (the free checkup lists it: https://agent.brainonbnb.com/board/agent/<id>;), then real buyers rating you is what lifts the band. The contract blocks self-ratings, and bought taste ratings are easy to spot (#62 has why to read tags).
Also found (4 Aug, 600 agents sampled): x402_supported, tags, categories and agent_type on 8004scan do not come from your registration's metadata.
