Summary

Shipping managed-agent policies now grant read-only access to the exact merged CA bundle produced during startup. The broader mutable /run/nemoclaw directory remains outside the policy grant.

Summary by CodeRabbit

  • Bug Fixes

    • Sandboxed agents can now access the managed startup certificate bundle in read-only mode.
    • Updated sandbox policies consistently support secure certificate-based connections without exposing broader runtime directories.
    • Access remains narrowly scoped and does not permit modifications to the certificate bundle or surrounding files.
  • Tests

    • Added coverage confirming the certificate bundle is read-only and that broader runtime-directory access remains blocked.

📝 Walkthrough

Walkthrough

The change adds /run/nemoclaw/managed-startup-ca-bundle.pem as a read-only path across seven managed agent policies. A Vitest suite verifies exact read-only access and rejects broader or read-write /run/nemoclaw access.

Changes

Managed CA bundle access

Layer / File(s) Summary
Add managed CA bundle read-only allowlists
agents/*/policy-*.yaml, nemoclaw-blueprint/policies/*.yaml
Agent and blueprint policies allow read-only access to the exact managed startup CA bundle path.
Validate exact filesystem access
test/managed-startup-ca-policy.test.ts
Parameterized tests load all seven policies and verify the exact read-only grant without broader runtime-directory or read-write access.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 8fb4f

This change grants read-only access to the exact managed startup CA bundle while keeping the broader runtime directory outside writable policy paths; no actionable merge-blocking risk remains after normal checks and review.

Warnings

Warnings do not block.

PRA-1 Warning — Test filesystem-policy enforcement for the CA bundle

  • Location: test/managed-startup-ca-policy.test.ts:27
  • Category: tests
  • Problem: The new test parses policy YAML but does not start a sandbox or exercise the filesystem-policy enforcer.
  • Impact: A path can appear in read_only while the active sandbox policy fails to grant reads or unexpectedly permits writes, leaving private-TLS startup broken or broadening access.
  • Recommendation: Add a runtime policy test that starts each affected sandbox policy, reads the exact CA bundle as sandbox, and verifies writes to the bundle and /run/nemoclaw are denied.
  • Verification: Inspect a new runtime test that applies each changed policy to a sandbox and checks sandbox-user reads and denied writes.
  • Test coverage: Start each supported agent with its baseline and permissive policy, verify sandbox can read /run/nemoclaw/managed-startup-ca-bundle.pem, and verify writes to that file and /run/nemoclaw fail.
  • Evidence: test/managed-startup-ca-policy.test.ts:27-34 parses each YAML file and asserts list membership only. scripts/checks/run-managed-image-openshell-e2e.ts:459-472 checks bundle metadata but does not apply the changed filesystem policies.

LOC Reduction / Codebase Simplicity Review

Why this blocks

  • PR #9391 now implements issue #9360 with a smaller diff and reuses initial-policy-real-policy.test.ts, SHIPPED_MANAGED_IMAGE_AGENTS, and MANAGED_STARTUP_MERGED_CA_FILE.
  • This PR creates a standalone hard-coded policy catalogue and literal CA path in test/managed-startup-ca-policy.test.ts.
  • It also changes agents/pi/policy-additions.yaml, although the managed-image contract classifies Pi as a candidate rather than a shipping agent.

Refactor direction

  • Coordinate on one implementation for #9360; the current comparator result favors #9391 after its duplicate table is removed and review threads are resolved.
  • Close this PR in favor of that implementation, or move the test into the existing real-policy harness, use the production constants, and remove candidate-Pi scope unless an accepted decision requires it.

Expected result

  • Keep one PR, one policy-path table, and one production-owned CA path constant.
  • Avoid merging parallel issue implementations or extending candidate scope through a shipping-policy defect.

Closing in favor of #9391, which reuses the existing real-policy harness and keeps candidate Pi out of the shipping policy scope.
