Observed
Requests are facts
Method, path, time, supplied User-Agent, and Vendor Agent message content are recorded as direct evidence.
Trust
Evidence without pretending certainty.
The reference deployment is designed to preserve useful research signals while making their limits visible.
Inferred
Identity stays uncertain
Probable client and confidence are stored separately. A User-Agent is evidence, never proof.
Network
Shortened salted IP hashes
Raw source addresses are not stored in experiment events; a truncated salted hash supports coarse correlation.
Referrers
Query data removed
Stored referrers retain only origin and path, excluding query strings and fragments.
Trials
Allow-listed tags
Trial tags are limited to 64 characters and a narrow non-identifying character set.
Current status
No certification claims
The experimental service does not claim an SLA, compliance certification, SAML SSO, or production readiness.
