Full details: Linked Issues checkExplanation The change adds verification evidence, but the provided summary does not show CLI or restore-path changes that report Shields: UP, the snapshot digest, timestamps, or re-lock confirmation required by issue Resolution Wire PolicyVerificationEvidence through manual restore, drift repair, inline auto-restore, and timer auto-restore paths. Use the shared renderer to report Shields: UP, the restrictive snapshot digest, the live policy read-back timestamp, and the config re-lock confirmation timestamp. Preserve fail-closed behavior and omit success evidence when verification fails.

Report verified posture after inline auto-restore.
When inline recovery succeeds, this path writes the enriched audit entry and returns. It does not call reportVerifiedShieldsPosture. The function already writes recovery output, so a CLI-triggered inline recovery can complete without the required Shields: UP output, snapshot digest, policy read-back evidence, or config-lock confirmation.
Proposed fix
appendAuditEntry({
action: "shields_auto_restore",
// ...
});
+ reportVerifiedShieldsPosture(sandboxName, {
+ policy: activation.verification,
+ configLockVerifiedAt: activation.configLockVerifiedAt,
+ });
return { attempted: true, restored: true };As per path instructions, “Trace every in-scope entrypoint and lifecycle path.”

Mock verifyAppliedPolicyDocument for this failure case.
policyVerificationSpy spies on confirmAppliedPolicySetSubmission in test/helpers/shields-flow-harness.ts at Line 503. This test throws before verifyAppliedPolicyDocument runs. A regression that ignores a failed live read-back after submission confirmation will still pass.
Expose the verifier spy from the harness. Make that spy throw while submission confirmation succeeds.

Thank you, @yimoj, for the careful work on this, including the fail-closed read-back handling, test coverage, and live validation. We have since merged #10722, which retires Shields from NemoClaw core. The Shields restore command and UP-posture reporting contract targeted here no longer exist on current main. After the branch was brought forward, the remaining diff only returns the policy read-back source and time from verifyAppliedPolicyDocument and tests it; the surviving production caller ignores that return value, so merging the residual change would not deliver any current user-visible behavior. Closing this as superseded by #10722. If a current policy workflow later needs a first-class verification receipt, we can revisit that as a focused change tied to an active consumer. Thanks again for doing the original investigation and implementation. |

Outcome
Successful Shields restoration now reports the UP posture, the restrictive snapshot digest, the live policy read-back time, and the config re-lock confirmation time. A missing or failed read-back still exits non-zero and emits no success evidence.
Reason
shields upalready verified the restored policy and config lock, but its exit-0 output only said that lockdown was active. Users and automation could not distinguish verified-and-silent success from a path that never verified the resulting posture.Related issues

This changes a security-sensitive policy restoration path. Three fresh-context reviewer passes covered correctness and fail-closed behavior, tests and closure evidence, and simplicity. The final gates found no actionable findings.
Live E2E used macOS arm64, Node.js 26, OpenShell 0.0.106, Docker 29.2.1 on Colima, a worktree-owned HOME, gateway port 12637, dashboard port 42640, and local Ollama. The issue is platform-independent, and the Node.js version does not control the host-side output or policy verification path.
The shared Linux host could not onboard because Docker bridge DNS was unavailable. Shared macOS state also contained an invalid foreign gateway record. The E2E used isolated state and did not modify or remove foreign resources.
