How PlukScore works

Pluk is the first public implementation of the Pluk Evaluation Standard (PES). One universal concept — demonstrated trustworthiness — measured through category-aware evidence modules.

The four trust dimensions

Every interaction is rated on the same four dimensions, regardless of category:

• Reliability
  Showed up, followed through, kept commitments on time.
• Competence
  Delivered work that met a reasonable standard for the field.
• Honesty
  Communicated accurately about scope, pricing, and outcomes.
• Commitment Fulfillment
  Fulfilled the specific agreement made with the customer.

Evidence levels

Every interaction carries an evidence level. Verified evidence carries more weight than opinion.

1. Level 1
   Unverified Experience
2. Level 2
   Account Verified
3. Level 3
   Interaction Supported
4. Level 4
   Independently Verified

Severity

Not every complaint is equal. Higher-severity claims require stronger evidence to affect a public score.

• Routine dissatisfaction
• Material failure
• Serious breach
• Alleged severe misconduct
• Substantiated severe misconduct

Confidence, not certainty

Every PlukScore ships with a Confidence tier reflecting evidence quantity, reviewer diversity, verification level, and time span.

• Low confidence
• Moderate confidence
• High confidence
• Very high confidence

Building PlukScore

We never invent a default score. Until an entity has enough interactions with sufficient evidence and diversity, it is marked Building PlukScore — an honest signal that we don't know yet.

Explainability & audit

Every score is computed server-side, snapshotted, and paired with an explanation record — the engine version, the evidence set, and the dimension breakdown. Every meaningful change is written to an audit trail.
