Typed contracts
Observed, forecast, modeled, reanalysis, satellite and synthetic records remain distinct.
PRODUCTION-GRADE DATA ENGINEERING
Every result begins with data identity.
HeatSafe records where environmental data came from, how it was retrieved, what it measures, which terms apply, how quality was assessed and whether the exact snapshot can be verified later.
Resilient retrieval
Retries, rate limiting, cache TTL, response hashes and metadata.
Quality reports
Duplicates, ranges, units, source URLs, licenses and provider flags.
Verifiable snapshots
Atomic JSONL artifacts, manifests, SHA-256 and record-count verification.
Official-source foundations
NOAA CDO, EPA AQS, EEA Air Quality, NASA FIRMS and ERA5-Land specifications.
Honest status
Implemented, local-normalizer, request-specification and registry-only states are explicit.
