Summary

Full NemoClaw uninstall discarded the gateway registration removal result, so a hard removal failure could still return success and erase local state. This change propagates that failure, stops later cleanup, and reports a bounded diagnostic without exposing command output.

Related Issue

Fixes #9859

Changes

  • Propagate gateway registration removal failures through full uninstall and final-sandbox cleanup.
  • Use one gateway-removal policy across uninstall, destroy, and Docker-driver registration recovery.
  • Use the legacy gateway destroy fallback only when gateway remove explicitly reports an unsupported command.
  • Treat a reported missing gateway as success only after a fresh gateway-list postcondition confirms absence.
  • Preserve state, skip later cleanup, and omit the success banner after a hard removal failure.
  • Report fixed, actionable diagnostics for current remove failures and legacy destroy failures without echoing untrusted output.
  • Document the full-uninstall and scoped-cleanup recovery behavior.

Type of Change

  • Code change (feature, bug fix, or refactor)

Quality Gates

  • Tests added or updated for changed behavior
  • Documentation updated for changed behavior
  • Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
  • Independent sensitive-path review completed on the current revision

A maintainer security assessment is recorded in #9860 (comment). The prior successful advisor run is https://github.com/NVIDIA/NemoClaw/actions/runs/34381998836. A current-revision advisor run is pending recovery from the runner's external APT index hash mismatch.

Verification

  • npm run validate:pr
  • npm run docs
  • npm run typecheck:cli
  • npm run checks:repository (1,899 files, 6,086 edges, zero cycles)
  • Focused CLI suites: 120 tests passed
  • Frozen-runtime registration failure regression: 1 test passed
  • Legacy fallback integration regression: 1 test passed
  • GitHub verifies the current head signature; the required DCO check passes
  • No secrets, API keys, or credentials committed

Review Note

The current comparison is 635 additions and 219 deletions across 17 files. The shared policy is intentionally housed in the existing gateway teardown authority module to preserve the repository architecture budget.

…removed

The full uninstall path discarded removeGatewayRegistration's result and
returned true unconditionally, so a failed 'openshell gateway remove' still
exited 0, printed the success banner, and wiped ~/.nemoclaw. Return the
result instead, matching finishScopedOpenShellCleanup in the same file.
removeGatewayRegistration already returns true for an absent gateway, so a
clean host is unaffected.

📝 Walkthrough

Walkthrough

The uninstall flow now reports bounded gateway-removal errors and propagates failure status. Regression tests verify sanitized diagnostics, nonzero completion status, skipped cleanup, and suppressed success output.

Changes

Uninstall gateway failure handling

Layer / File(s) Summary
Format and propagate gateway failure
src/lib/actions/uninstall/run-plan.ts
Gateway removal and legacy destruction report operation-specific, sanitized failures with connection and exit-status details. Resource cleanup preserves the gateway-registration result. Formatting-only changes do not alter behavior.
Validate uninstall failure behavior
src/lib/actions/uninstall/run-plan.test.ts, src/lib/actions/uninstall/run-plan-gateway-segregation.test.ts, src/lib/actions/uninstall/run-plan-preserved-registry.test.ts
Regression tests verify sanitized warnings, nonzero completion status, skipped cleanup, no destroy fallback for current removal failures, legacy destroy failure handling, and gateway-specific command matching. The Ollama proxy test keeps its existing assertions.

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

Merge Risk: 🔵 Low · up to ac95e

The uninstall path now reports gateway-removal failures and preserves local state, but regression coverage does not directly verify that state deletion and the success banner remain suppressed on failure, leaving a bounded merge-readiness risk for owner follow-up.

Hard openshell gateway remove failures are still reported with the absence/no-op message already removed or unreachable, discarding actionable causes such as connection refusal. The linked issue specifically identifies this misreporting, and the new test codifies it.

Use absence wording only for GATEWAY_ALREADY_ABSENT. For other failures, emit a distinct registration-removal failure diagnostic with safely bounded and redacted command detail. Update tests to distinguish absence from hard failure. Also assert that a hard failure preserves state, skips binary/state cleanup, and does not print the success banner. The nonzero exit and retryable partial-cleanup ordering otherwise look correct.

Review and Security Follow-Up

Addressed both current review findings in the latest PR revision.

  • Confirmed gateway absence keeps the existing no-op wording.
  • Hard removal failures now report a distinct, fixed diagnostic with the exit status and a recognized connection-refusal cause. Untrusted command output is never copied into the message.
  • The regression test proves a hard failure preserves state, stops before CLI and state cleanup, omits the success message, exits nonzero, and does not expose a credential-shaped value from command output.

Security review: PASS. The failure path is now fail-closed and preserves retryable state. No input parsing, authorization, network policy, dependency, credential storage, or concurrency behavior changed.

Validation:

  • All 40 focused uninstall plan tests passed.
  • npm run validate:pr passed on current main.
  • Normal pre-commit, commit-message, and pre-push hooks passed.
  • GitHub reports both new revisions as Verified.
  • The CodeRabbit thread is resolved after the validated repair.

The current diff is 106 additions and 51 deletions across two files, so it is not a large increase. Fresh repository checks and repository-routed human re-review remain required before merge.

Advisor Blocker Addressed

The current revision updates the stale current-command regression to require a nonzero result, the fixed removal-failure diagnostic, no legacy fallback, no state deletion, no later cleanup stage, and no success banner.

It also adds the missing legacy fallback failure case. That case proves the unsupported current command reaches legacy destroy, a hard destroy failure returns nonzero, state and later cleanup remain untouched, and credential-shaped stderr is absent from the diagnostic.

The expanded focused run passed 67 tests across both uninstall suites. Normal pre-commit, commit-msg, and pre-push validation passed. The synchronization and test commits appear as Verified in GitHub.

Fresh checks and independent re-review are required before merge.

Current Revision Validation

The PR-related preserved-registry failure came from a stale test fixture that made gateway removal fail while the test was exercising later provider and sandbox cleanup. The fixture now returns success for gateway removal and keeps the intended later no-op behavior.

The unrelated installer-integration failure did not reproduce. The same revoked-host-key case passed unchanged in 426 ms, so I classified that failure as transient.

Validation after synchronizing current main:

  • 71 focused uninstall tests passed across the gateway-segregation, preserved-registry, and run-plan suites.
  • npm run build:cli passed.
  • npm run validate:pr passed.
  • Every PR commit appears as Verified in GitHub.

Fresh CI and automated review are running. The existing human change request still requires review of the corrected behavior before merge.

Base Refresh

Current main merged cleanly into this PR. The automatic merge preserved the uninstall failure behavior and its regression coverage.

Validation passed:

  • 71 focused uninstall tests
  • Normal commit-message and pre-push hooks
  • npm run validate:pr, including repository checks, growth guardrails, secret scanning, and CLI TypeScript checks

GitHub reports the merge commit as verified, and its DCO declaration is present. GitHub's standard fork workflow gate was approved only for the new runs. Fresh checks are running.

Independent human approval remains required because I contributed repair commits. I did not issue a reviewer request.

Current Main Synchronization

Synchronized the PR with current main after the shared installer and reviewed dependency audit repairs merged.

Validation:

  • 95 focused uninstall, installer, and reviewed-audit workflow tests passed.
  • Normal commit and push hooks passed, including plugin and CLI type checks.
  • GitHub reports the synchronization commit as Verified.
  • The PR change remains 190 additions and 56 deletions across the same four files.

Fresh repository checks and repository-routed independent sensitive-path review remain required before merge.

CI Failure Classification

The required CLI shard 2 failure is a transient test timeout outside this PR.

Evidence:

  • The failed file, src/lib/inference/serving/host-local-vllm-selection.test.ts, is unchanged by this PR.
  • The shard had run for more than seven minutes and emitted a process listener pressure warning before the five-second timeout.
  • The affected synchronous test passed in five consecutive isolated runs. Each run passed all eight file tests, and the test body completed in about one second.
  • The other 11 CLI shards passed, as did the focused uninstall, installer, and reviewed-audit workflow tests.

This is classified as test and runner contention, not an uninstall regression. Repository retry policy does not authorize a broad manual workflow rerun for this case, and there is no corrective branch change to publish. The PR remains blocked pending a repository-owned fresh check or authorized human direction.
