identity & authorization patterns.
Use 420 Identity, Registry and Names as shared discovery and authorization primitives without treating human-readable labels or application metadata as proof of authority.
separate identity from authority
An identity record can describe an account or entity, but privileged actions should still be authorized by explicit contract roles, signatures, ownership state or other canonical permission checks.
resolve names safely
Human-readable names should resolve to canonical records before use. Applications should display both the friendly name and the underlying address for sensitive actions.
default deny
Permissioned application paths should fail closed when required identity, role, registry or entitlement checks are missing, expired or ambiguous.
cache carefully
Identity and authorization data may change. Clients that cache records should define freshness rules and re-check canonical state before high-value or privileged actions.
deployment values
Canonical contract addresses, schemas and release-specific interfaces will be published after qualification. Do not hard-code provisional values into production applications.
