Why this assessment

  1. shrinkage — synthetic.public_ratings: raw 4.60 from 210 reviews shrinks toward prior 3.8 (n0=30) → 4.500.
  2. combine_sources — Inverse-n weighted shrunk mean across 1 PUBLIC source(s) is 4.500 stars → 87.5/100.
  3. paid_claim_isolation — DECLARED/INFERRED/DISPUTED rows can exist on the ledger but do not increase reputation, confidence, depth, or provisional assessment. Paying or claiming cannot buy a higher number.
  4. composite_placeholder — research.v0 composite is 0.70*reputation + 0.15*confidence + 0.10*depth + 0.05*freshness. Weights are experimental placeholders.
  5. parent_non_inheritance — Only evidence bound to this entity_id was used. Parent/brand ratings are not mixed into location reputation.
