Why: Project retrieval hits, tool results, and saved visible analysis must be individually traceable and fully analyzed before later project actions consume them.
Evidence: RED tests first showed missing run-source capture, tool-result capture, and run-wide preflight; go test -p 1 ./... and go build ./... passed; isolated PostgreSQL source, migration, audit, and context tests passed.
Impact: Persist actual run-bound sources with current-status checks and exact manifests behind the disabled X3 assembly gate; no live product path, migration, deployment, or release is enabled.
