01 / DECISION
When this primitive earns a place
Use Analytics Engine for high-cardinality operational events that need aggregation without becoming transactional state.
02 / ARCHITECTURE
Build the smallest defensible path
Write the questions first, define stable indexes and numeric blobs, avoid raw secrets or payloads, sample intentionally, and version the event contract.
- 01Name the contract
Use Analytics Engine for high-cardinality operational events that need aggregation without becoming transactional state.
- 02Add one primitive
Write the questions first, define stable indexes and numeric blobs, avoid raw secrets or payloads, sample intentionally, and version the event contract.
- 03Capture failure evidence
Validate event shape, query known fixtures, prove aggregate totals, document sampling, and confirm no credential or private identifier is emitted.
03 / REPRODUCE
Evidence before confidence
Validate event shape, query known fixtures, prove aggregate totals, document sampling, and confirm no credential or private identifier is emitted.

The production boundary
Telemetry can become surveillance or an accidental personal-data store. Cardinality without query discipline creates cost without insight.
05 / FIRST-PARTY SOURCES
Keep first-party sources authoritative
Product behavior, limits, pricing, and availability can change. Re-check these sources before acting.
