Data Freshness & Provenance Register
Transparent audit log of authoritative upstream datasets, automated integrity gates, and active production releases. Every geographic entity in Pincodez is traceable to official Government of India registries.

1. Zero Synthesized Data
Pincodez strictly prohibits data hallucination. If a coordinate, post office beat, or sub-district link is missing or ambiguous in official records, it is explicitly marked as UNKNOWN rather than estimated.
2. Bounding Envelope Invariants
All coordinates are verified against India's continental spatial boundaries: Latitude 2.5° to 38.5° N, Longitude 63.5° to 99.5° E. Every PIN must conform to exact 6-digit numeric syntax with valid postal zone prefix (1–8).
3. Automated Circuit Breaker
Before any release database is activated, an automated diff comparator checks record count stability. If record counts unexpectedly drop by more than 5%, automated deployment halts immediately to prevent upstream data loss.
