1. Trust Score Algorithm: The composite TIA Score (0-100) is calculated based on Reliability (punctuality, communication), Craftsmanship (peer audits, review rating), and Community (workshops hosted, chapter contributions).

2. Progression Tiers: Progression is sequential: Unverified → Verified (Identity check) → Certified Pro (Skill exam & portfolio audit) → Master Creator (Chapter panel validation) → TIA Fellow → TIA Legend (National recognition).

3. Audit Criteria: Higher tiers require background checks, GST certification for businesses, live skill demonstrations, and active mentorship of junior guild members.

4. Status Revocation: Any ethical violation, off-platform payment attempt, or drop in the composite Trust Score below the tier threshold will initiate a verification review and potential downgrade.
