Reviewed exact head e1b3f50. The live fixture now uses a bounded proxy-aware curl HEAD probe while preserving the allowlisted subprocess environment and content-free diagnostics. Verified the focused integration suite locally after the required plugin build: test/mcp/mcp-bridge-servers.test.ts, 13/13 passed, including Node-fetch-unreachable proxy coverage, consecutive readiness, output omission, and split-secret handling.

PR #11156 run 34504102261 reproduced this fixture race in shard 4 on job 102962375118 and retry job 102968908882: https://github.com/NVIDIA/NemoClaw/actions/runs/34504102261/job/102962375118 and https://github.com/NVIDIA/NemoClaw/actions/runs/34504102261/job/102968908882. Under coverage, this proxy-aware test still lets fake cloudflared exit after the hardcoded sleep 2 before the readiness probes finish. Please keep that fake process alive until the registered cleanup stops it. In the same fixture, please make fake curl return 405 only for the intended HEAD request to the exact https://fixture-cleanup-123.trycloudflare.com/mcp target. These fixture-only changes avoid increasing production timeouts or adding scenarios.

<!-- markdownlint-disable MD041 --> ## Outcome The proxy-aware MCP tunnel fixture now stays alive until its registered cleanup stops it. Its fake curl returns readiness only for a HEAD probe to the exact `/mcp` target. ## Reason The fixture hardcoded a two-second process lifetime. Under coverage, the fake cloudflared process exited before the readiness probes completed in PR #11156 run 34504102261, including retry job 102968908882. PR #11460 merged the proxy-aware probe without this fixture repair. ## Changes - Replace the fixed fake-cloudflared sleep with the cleanup-owned keepalive pattern already used by the adjacent fixture. - Require fake curl to receive `--head` and `https://fixture-cleanup-123.trycloudflare.com/mcp` before it returns 405. ## Verification - `npx vitest run --project integration test/mcp/mcp-bridge-servers.test.ts` - 13 tests passed after the current-main refresh. - `NODE_OPTIONS=--max-old-space-size=8192 npm run validate:pr` - passed against main at `8d6643be25fb9ae80f6e2357b45b69ef4f3e0416`. - `git diff --check` - passed. - GitHub reports both commits through `8e09dc0615ad746f7c623de8992602754f89bf1a` as Verified. - The diff contains no secrets, API keys, or credentials. ## Review notes Failure evidence: https://github.com/NVIDIA/NemoClaw/actions/runs/34504102261/job/102962375118 and https://github.com/NVIDIA/NemoClaw/actions/runs/34504102261/job/102968908882. `npm run review:local` did not complete. Its trusted sandbox could not connect to the OpenShell gateway, then cleanup reported EACCES for its temporary context file. Focused tests and the repository PR validation passed. --- Signed-off-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com> Signed-off-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com> Co-authored-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com>

## Outcome Use native Node.js network-interface discovery in the sandbox. Remove the obsolete ciao preload and its startup, connect-session, recovery, and packaging wiring. ## Reason Pinned OpenShell 0.0.106 permits the route queries used by native interface discovery. The old preload masks failures by returning an empty interface map and catching gateway exceptions. ### Related issues Closes #11260. Part of #11255. ## Changes - Delete `ciao-network-guard.js` and its exclusive consumers. Keep the remaining preloads, managed recovery order, and broader safety-net behavior. - Retain permission, credential, failure and recovery coverage. Add native interface observations to the existing lifecycle test; require real loopback data, no retired preload and no interface error. - Refresh the two existing Pi receipts and their authority hashes from authenticated same-run artifacts. Their image inputs retain exact source parity. - Supply the existing buffered command executor to the legacy recovery test fixture. Main's adapter migration made that dependency necessary; without it, the fixture rolled back before attempting legacy recovery. This correction adds 10 test-only lines across two existing files. The current diff changes **30 files: 122 additions, 327 deletions (205 fewer lines)**. Production code remains **11 additions and 147 deletions (136 fewer lines)**. No new runtime state, dependency, registry, permission rule, compatibility path, retry, timeout extension or live test target. ## Verification - Both builds and 609 focused tests passed on `eb679d2`; 61 existing focused fixture/reconnect tests passed for the correction on `d6ce89e`. - Main `8d6643b` was merged without conflicts as `45d1b44`. Canonical `npm run validate:pr`, both builds, Pi source parity, all 13 MCP fixture tests and all 42 legacy-fixture support tests passed on that merged commit. - [Managed-image qualification on eb679d2](https://github.com/NVIDIA/NemoClaw/actions/runs/34503663476) passed: all producers, both MCP passes and all-agent activation. Authenticated consumer evidence records 12 agent turns, restart/recovery and cleanup for all three shipped agents, with no image-build fallback. - [Shared/root image security](https://github.com/NVIDIA/NemoClaw/actions/runs/34503736251) passed all seven active jobs, including security/glibc execution and cleanup. - [Native qualification on eb679d2](https://github.com/NVIDIA/NemoClaw/actions/runs/34507706772) passed Docker and Podman security posture and Pi AMD64 lifecycle. Both OpenClaw runtimes returned native interfaces before doctor and after recovery, with the retired guard absent and native-state checks clean. Pi verified real inference, session/profile preservation, credential/network boundaries and cleanup; its existing automatic retry recovered two provider-overload responses. - That first recovery case passed ordinary recovery, stable process identity, real Docker restart and inference, then failed during legacy fixture creation because of the missing executor. The [recovery-only run on d6ce89e](https://github.com/NVIDIA/NemoClaw/actions/runs/34512598930), using unchanged qualified `eb679d2` images, passed legacy fixture creation, handoff and Docker restart. Actual legacy recovery then failed in the unchanged privileged Docker target selector because multiple labeled containers matched; late inference was not reached. The exact matching rows were not retained, so the backup/replacement explanation remains a source-supported inference. Both cleanup actions passed. The other passing cases are retained as ancestor evidence; their dependency graphs do not import the changed fixture. - Broad OpenClaw `doctor --lint --json` reported 34 security/optional-skill warnings per runtime. Native-state diagnostics reported zero findings; no warning-free broad-doctor result is claimed. - [Current-head CI](https://github.com/NVIDIA/NemoClaw/actions/runs/34519099013) and [managed-image qualification](https://github.com/NVIDIA/NemoClaw/actions/runs/34519099004) are running for `45d1b44`. The diff contains no secrets, API keys, or credentials. ## Review notes Independent source and merge reviews found no actionable issue in this change. CodeRabbit completed its `d6ce89e` review with no actionable findings; current `45d1b44` review feedback is pending. The PR is ready for review, and final CI must be clean before merge. Main's [#11460](#11460) fixes the inherited MCP unit regression and is now included. The formerly failing case passes locally; this PR introduces no MCP-specific repair. OpenShell policy, capability restrictions, intentional discovery settings, managed Docker/Podman recovery authority, and upstream credential custody remain unchanged. The host-test prerequisite from #11309 landed independently on main before this branch consumed it to resolve conflicts. This PR targets main independently. --- Signed-off-by: Aaron Erickson <aerickson@nvidia.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Bug Fixes** - Simplified runtime recovery to rely on the sandbox safety net while retaining proxy, cancellation, and discovery protections. - Updated gateway startup and recovery behavior to no longer require the removed network guard. - Improved legacy keepalive fixture command execution and recovery validation. - **Tests** - Expanded end-to-end checks for native networking before and after recovery. - Updated guard-chain, preload, and recovery coverage to match the streamlined runtime setup. - **Chores** - Refreshed agent qualification artifacts and accepted validation digests. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Aaron Erickson <aerickson@nvidia.com>

## Outcome Interactive connect, portable launch, and agent dispatch use typed OpenShell sessions. The CLI backend owns argv, stdio, signals, output capture, cancellation, and terminal restoration. ## Reason Complete the interactive-session slice while preserving lifecycle locks, exit status, stdin behavior, and recovery policy. ### Related issues Closes #10994. Refs #9804. ## Changes - Extend the existing CLI backend with a typed session contract and retire action-owned process helpers. - Move the existing process supervisor and bounded capture runner into core. Ollama recovery retains its existing timeouts and environment policy. - Protect process ownership, cancellation, terminal cleanup, transport exit codes, and retired exports with regression tests. - Lower existing architecture limits to reflect removed dependencies: runtime fan-in 48 to 47; connect fan-out 43 to 41. - Stacked on #11358. SDK installation policy is unchanged from canonical main. ## Verification - 382 focused tests passed; all 40 launch tests passed after protecting transport exit-code preservation. - Integration boundary checks: 64 passed, 52 platform-skipped. The reviewed connect assertion repair passed all 57 connect-flow tests. - Integrated the required fixture fix from #11460 after evaluation settled. The previously failing proxy-aware fixture test passed locally: one passed, 12 unselected. - CLI build and full CLI TypeScript checks passed. Latest publication validation: `NODE_OPTIONS=--max-old-space-size=8192 npm run validate:pr` passed at `b55a2e3eb25e4c2ae3ae6bebff0ee2a2c10a99b7` against canonical main `8d6643be25fb9ae80f6e2357b45b69ef4f3e0416`. - Broad `npm run check` hit inherited hadolint warnings in Dockerfiles identical to canonical main; its manual coverage stage did not run. - Local Advisor unavailable because the OpenShell gateway refused connection; cleanup also returned EACCES. No independent Advisor result is claimed. - Reviewed process ownership, cancellation, locking, stdin, terminal behavior, and scope. No secrets or credentials are included. ## Review notes Rebecca approved only the two lower architecture limits, recorded in [issue 9804](#9804 (comment)). All other validation settings and executables match the trusted base. This does not waive CI or merge requirements. Pre-publication self-review covers NVIDIA/NemoClaw candidate b55a2e3 and its session behavior. The canonical comparison also includes sensitive version-probe files inherited from #11358. Independent review remains required. CodeRabbit's session-spy finding is repaired; its inherited SDK-policy suggestion is excluded. --- Signed-off-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added session-based sandbox connections and command execution with structured outcomes, cancellation, signal handling, and output capture. - Added support for interactive and captured sandbox sessions with improved terminal and environment handling. - **Bug Fixes** - Improved process cleanup and exit-code reporting for interrupted or failed commands. - Added a proxy-aware fallback for MCP tunnel readiness checks. - Strengthened validation of trusted gateway runtime templates. - **Tests** - Expanded coverage for sandbox sessions, SDK installation, process handling, and gateway workflows. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Julie Yaunches <jyaunches@nvidia.com> Signed-off-by: San Dang <sdang@nvidia.com> Signed-off-by: Charan Jagwani <cjagwani@nvidia.com> Signed-off-by: Prekshi Vyas <prekshiv@nvidia.com> Co-authored-by: J.

## Outcome MCP registration, recovery, session reconciliation, and rebuild checks await typed SSH command results. The transport adapter owns SSH configuration and process execution while consumers retain their status, output, and fallback behavior. ## Reason Complete the SSH command-consumer slice without changing recovery policy. ### Related issues Closes #10992. Refs #9804. ## Changes - Use the typed SSH adapter from #11358, preserving gateway authority, credential filtering, legacy host aliases, timeouts, diagnostics, and temporary-file cleanup. - Await existing SSH consumers and keep snapshot projection repair inside its lifecycle lock. - Update regression tests to exercise asynchronous completion. The SSH credential test isolates binary lookup so it works without an installed OpenShell. - Stacked on #11358. Interactive sessions remain in #11462; converting separate Hermes OpenShell exec paths to SSH remains outside this slice. ## Verification - Conflict repair `832e75b21ddbf73d5c41364b526cb01454fa9921` integrates parent #11358 at `1ca52558fb34be39473fe09d48f71454cc0b5219`. The SSH adapter uses the hostname selected from OpenShell configuration for both version probes and command transport, preserving command diagnostics and temporary-file cleanup. - Focused conflict validation: `node node_modules/vitest/vitest.mjs run --no-cache --project cli src/lib/adapters/openshell/sandbox-ssh-cli.test.ts src/lib/adapters/openshell/sandbox-ssh-host.test.ts src/lib/adapters/sandbox/command-transport.test.ts` — 57 passed; the same command selecting `src/lib/sandbox/version.test.ts` — 33 passed. Strict adapter lint/typing and formatting passed. These tested owners remained byte-identical when incorporating the newer parent. - Fresh CLI/plugin builds, `npm run validate:pr`, commitlint and pre-push passed in credential-free, network-disabled isolation against canonical main `e98c28186f07c618ece7a362513728b5f83a9c53`. The canonical Podman workflow-policy helper was overlaid for independent validation; all 43 resolved tool identities stayed verified and no source file changed. GitHub verified all 12 newly included commits. Fresh CI and automated review are pending. - Focused consumer coverage: 157 passed, 14 skipped; recovery coverage: 88 passed. The broader changed-test selection passed 257 with 14 skipped. - Async test repairs passed 57 focused cases. Later isolation checks passed 70 tests and skipped 10; one unrelated analyzer test requires Linux `/proc` and fails locally on macOS. - Integrated the required fixture fix from #11460 after evaluation settled. The previously failing proxy-aware fixture test passed locally: one passed, 12 unselected. - CLI/plugin builds and full CLI TypeScript checks passed. Latest publication validation: `NODE_OPTIONS=--max-old-space-size=8192 npm run validate:pr` passed at `4423e8a30aeb35e453889b92c7f5b4b853eb7281` against canonical main `8d6643be25fb9ae80f6e2357b45b69ef4f3e0416`. - Local Advisor unavailable due review infrastructure failures. Hosted Advisor exhausted its provider budget. Some snapshot tests timed out locally; no timeout or lock behavior was changed to suppress them. - Prior-head managed-image activation and both exact MCP discovery runs passed. Fresh CI and automated review are required for this update. - Reviewed async ordering, locking, command failures, and gateway authority. No secrets or credentials are included. ## Review notes The conflict update was self-reviewed against both parent versions. The manual resolution is limited to SSH host selection; asynchronous completion, gateway/environment restrictions, failure diagnostics and cleanup remain covered by the existing transport and version tests. The previous CodeRabbit review of `4423e8a` reported no actionable findings. No new Advisor result is claimed. The earlier GPU-selection failure was a GitHub API time-budget failure during publication verification, before SSH execution; it was not rerun. --- Signed-off-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com> Signed-off-by: Carlos Villela <cvillela@nvidia.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Improvements** - Sandbox commands, MCP adapter registration, inspection, removal, recovery, and restore workflows now complete asynchronously with improved operation sequencing. - SSH command failures now preserve exit codes and command output, making troubleshooting more informative. - Public tunnel readiness checks now support proxy and CA settings, bounded probes, and clearer transport-error handling. - SDK installation checks now use verified offline packages and confirm successful client connectivity. - **Tests** - Expanded coverage for recovery, lifecycle, installation, tunnel readiness, and failure scenarios. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Carlos Villela <cvillela@nvidia.com> Co-authored-by: Rebecca Sliter <571084+rsliter@users.noreply.github.com> Co-authored-by: Carlos Villela <cvillela@nvidia.com>

Outcome
Managed-image MCP discovery uses the runner's proxy-aware curl client to validate public quick tunnels. The readiness gate retains HTTPS-only transport, verified TLS, bounded timeouts, three consecutive exact-status probes, and redacted failure diagnostics.
Reason
Managed-image run 34484915588 published a fresh quick-tunnel URL on every attempt, and every cloudflared process stayed alive. Both OpenClaw discovery jobs still failed because the Node 22.19 fetch probe raised TypeError for each public HEAD /mcp request. The downstream E2E run 34485094547 then stopped before the requested tests ran.
PR #11454 merged the reproducing regression. This follow-up implements the repair against that merged test.
