 ## Summary
 
-> To be filled on completion
\ No newline at end of file
+Implemented `LocalOperationEnv` (Layer 0 — `Arc<OperationRegistry>`, reachability
+check, authority switch, fresh metadata, inherited deadline/env) and
+`CompositeOperationEnv` (session → connection → base overlay dispatch via
+`contains()` probe per ADR-024). `ScopedOperationEnv` checked before overlay
+dispatch. 13 new env tests (93 total in call crate). Clippy clean. Merged to
+develop.
