Tiers explained
- Tier A: Authoritative primary source — government publisher or audited document. Highest confidence.
- Tier B: Industry association or first-party (school's own site). High confidence subject to self-reporting bias.
- Tier C: Derived from a Tier A/B source (e.g., extracted feeder relationships). Confidence inherits from the underlying source.
- Tier D: User-contributed (claim flow, reviews). Always labelled, never blended into core facts.
