 ## Stage 9: Collect Execution Observations Safely
 
-**Status:** Pending. **Depends on:** Stage 8.
+**Status:** Complete (2026-09-24). Added Audita-owned logical-call and execution
+event records with call IDs, diagnostic attribution, short synchronized capture,
+copying snapshots, and terminal-only usage aggregation. Preserved runner wall
+and per-validator timings. Tests cover preparation failure, undispatched
+admission, known zero versus unknown usage, partial failed repairs, no double
+counting, concurrent attribution, and the real role-client hook. `go test
+-race ./internal/framework/llm ./internal/framework/runner`, focused package
+tests, and `go build -o /tmp/audita-stage9-build ./cmd/audita` passed;
+`git diff --check` passed. Report/artifact serialization follows in Stage 10.
+**Depends on:** Stage 8.
 **Owns:** Audita-owned execution record types and collector in the LLM boundary,
 runner attribution, and concurrency/observation tests.
