+# Epic #1491 production readiness audit
+
+Audit timestamp: 2026-06-26T12:13:23Z
+
+Scope:
+
+- Epic #1491: Keiko Agent-Native Editor Foundation and Runtime Governance.
+- Final child issue #1389: Runtime, Git, and command UX with audit evidence.
+- Integrated dependency: Epic #470 governed Git delivery, as merged into the #1491 feature branch by PR #1551.
+
+## Current delivery state
+
+- #470 remains closed as completed and is treated as an integrated dependency, not as an open workstream.
+- PR #1551 is merged into `feat/keiko-agent-native-editor-foundation-and-runtime`.
+- #1389 implementation is present on the #1491 feature branch, but the issue must stay open until this audit PR is merged and closure evidence is posted.
+- #1491 is not yet merged to `dev`; epic closure must wait for a green PR from the feature branch to `dev`.
+
+## Audit findings
+
+The audit did not find a second Git write path, a browser shell escape, or a container execution bypass.
+The editor runtime composes existing governed surfaces:
+
+- Read-only repository state stays on `/api/git/status` and `/api/git/diff`.
+- Git mutations stay on `/api/git-delivery/*` and the governed Git, pull request, and merge windows.
+- Command execution uses server-discovered task ids only.
+- Container execution uses the server-frozen catalog only.
+
+Two production hardening gaps were found and fixed:
+
+1. Command and container run controls could accept rapid duplicate submits before React rerendered the `running` state.
+   The widgets now use the synchronous in-flight ref as the immediate guard, and the run buttons are truly disabled during execution.
+2. Runtime-linked windows could retain stale project paths when an existing window was reconfigured from the Runtime hub.
+   The Runtime hub and command/container windows now synchronize their project path from updated window configuration.
+
+## Verification matrix
+
+Local targeted verification:
+
+- Runtime hub, command, container, and widget registry tests passed.
+- Git delivery evidence check passed.
+- Editor documentation link check passed.
+
+Required full verification before merge:
+
+- `npm run typecheck`
+- `npm run lint`
+- `npm run arch:check`
+- `npm run arch:check:negative`
+- `npm run test:coverage:quality`
+- `npm run build --workspace @oscharko-dev/keiko-ui`
+- `npm run check:git-delivery-evidence`
+- `npm run check:editor-doc-links`
+- `npm audit --audit-level=moderate --workspace @oscharko-dev/keiko-ui`
+
+Additional browser verification should be run only if this audit PR expands beyond the current UI hardening and documentation changes.
+
+## Closure requirements
+
+#1389 can be closed after this audit PR is merged and the issue receives a closure comment linking:
+
+- the merged implementation PR #1551,
+- this audit PR,
+- the local and GitHub check evidence,
+- the retained Git Delivery boundary.
+
+#1491 can be closed only after:
+
+- every migrated child issue is closed with correct status labels,
+- #1389 is closed,
+- this audit evidence is merged,
+- a PR from `feat/keiko-agent-native-editor-foundation-and-runtime` to `dev` is merged green,
+- the epic receives a final closeout comment.
