 Status: in_progress
 
 DoD:
-- the highest-risk registry queries use `sqlx::query!` / `query_as!`
-- compile-time SQL verification is enabled in normal backend workflow
-- runtime-only queries remain only where dynamic SQL is truly required
+- domain and registry models use typed timestamps instead of `String`
+- SQL row decoding uses timestamp types directly where possible
+- API serialization stays RFC 3339 compatible
 
 ## Next
 
-- `feat/typed-timestamps`
+- `feat/error-structure-normalization`
