Outcome

Keeps an MCP-bearing sandbox rebuild on one recorded OpenShell runtime target across preflight, delete, recreate, restore, process recovery, and final relock. Target drift fails closed with the original sandbox preserved and a concrete recovery action.

Reason

Rebuild crosses gateway recovery, policy, Shields, DCode, onboarding, SSH, plugin restore, messaging, and process-recovery boundaries. Each dependent phase must reuse the same target or a transaction can inspect one sandbox and mutate another with the same name.

Related issues

Refs #10514
Refs #9833

Changes

  • Resolve and pin one MCP runtime selection before live rebuild probes, then retain it in the recreate journal and preparation state.
  • Carry the selection through DCode checks, policy and Shields work, deletion, inner onboarding, SSH and state restore, messaging, process recovery, and final relock.
  • Consolidate DCode gateway selection on the shared recovery helper while preserving its distinct failure contract.
  • Replace ambient OpenShell selectors at every affected subprocess boundary and restore the caller's environment on success and failure.
  • Add target-drift, hostile-selector, journal, restore, recovery, and post-restore regression coverage.

Verification

  • npm run build:cli — passed.
  • npm run typecheck:cli — passed.
  • Focused rebuild CLI suites — 413 tests passed and 14 expected skips.
  • Focused rebuild integration suites — 225 tests passed.
  • npm run checks:repository — passed.
  • Normal pre-push TypeScript hook — passed.
  • git diff --check and a credential review of the diff — passed; no secrets, API keys, or credentials are included.

Review notes

Stack 4 of 4 extracted from #10621. Depends on #10816; review this PR against codex/10621-destroy-target.

The broad parallel changed-test run encountered shared portable-host lock contention. The same owning suites passed in serial, which is the evidence reported above.

Summary by CodeRabbit

  • New Features

    • Rebuilds and recovery operations now consistently use the selected OpenShell gateway, workspace, and TLS settings.
    • Authoritative rebuild resumes preserve and restore their selected runtime configuration across preflight, restore, and post-restore steps.
    • Sandbox restoration, messaging, MCP, inference, and configuration checks support the selected runtime context.
  • Bug Fixes

    • Prevented ambient endpoint and token settings from overriding the selected runtime.
    • Operations now fail safely when the selected gateway is unavailable or mismatched.
    • Host-local supervisor controls are blocked when they could target the wrong runtime.

📝 Walkthrough

Walkthrough

OpenShell runtime selection now propagates through rebuild, recovery, probing, forwarding, and restore flows. Selected gateway, workspace, TLS, and environment values override ambient settings. Tests cover target pinning, environment cleanup, gateway mismatches, supervisor refusal, and state restoration.

Changes

Frozen runtime selection

Layer / File(s) Summary
Runtime selection entry and preflight
src/lib/onboard/*, src/lib/actions/sandbox/rebuild-preflight-*, src/lib/adapters/openshell/gateway-drift.ts
Authoritative rebuild and preflight paths resolve, validate, and apply the selected OpenShell runtime.
Rebuild journal and phase propagation
src/lib/actions/sandbox/rebuild-*.ts
The selected runtime is persisted in the rebuild journal and passed through backup, destroy, MCP, messaging, restore, and post-restore phases.
Process recovery and forwarding
src/lib/actions/sandbox/process-recovery.ts, src/lib/actions/sandbox/forward-recovery.ts
Recovery, readiness checks, supervisor actions, and port forwarding use selected runtime command options. Host-local supervisor control is rejected for selected runtimes.
Selected-runtime state restoration
src/lib/state/*
OpenClaw, SSH, plugin discovery, cleanup, extraction, validation, and state-file restoration use the selected runtime environment.
Runtime routing regression coverage
src/lib/**/*.test.ts, test/**/*.test.ts
Tests verify frozen target routing, environment replacement, gateway mismatch handling, supervisor refusal, and propagation across rebuild and restore operations.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to dba1c

Interrupted rebuilds and non-default-workspace forwarding can still target a different OpenShell workspace than the recorded runtime. Resolve these routing defects before merge.

Requesting changes because rebuild makes the lower-stack target escapes reachable in post-restore recovery. Selected exec probes can still fall back to local Docker, and the managed supervisor dependency remains host-local and unselected. The Shields phases are also blocked by #10816’s privileged-control finding. Please land the fail-closed fixes in #10814#10816, restack this PR, and add negative tests proving an external selected target never invokes local Docker or local supervisor control.

P0

  • None.

P1

  • Two inline findings.

No additional P0/P1 was found in the exact stacked diff. Accepted #10514 supplies the product-scope decision.

Approval is also withheld because this stack depends on #10816, which remains changes-requested with failing/incomplete exact evidence. On this SHA, CI, Images, and E2E are green and both commits are Verified, but all nine Advisor specialists failed and CodeRabbit reports that its review was skipped. Re-evaluate after the two target-binding paths are fixed, the lower stack is accepted/restacked, and all exact automated review evidence succeeds.

Please re-review the current head. Rebuild now preserves the selected runtime through backup, delete, recreate, restore, forwarding, MCP, DCode, and onboarding; unavailable privileged control fails closed.

@prekshivyas I will re-review the current head. I will verify runtime-target preservation across the rebuild flow and fail-closed behavior for unavailable privileged control.

Test runtime propagation through outcomes, not mock arguments.

These assertions lock the implementation to call counts and reference identity. Make each mocked boundary return a distinct success or failure result from the received runtime fields. Then assert the public preflight outcome.

Approved exact head 4bbe5fa after independent review of the stacked diff. Fixed prepared-only MCP rebuilds so they do not claim external runtime authority, updated the stale architecture caps to their measured values, and verified target continuity through preflight, delete, recreate, restore, process recovery, messaging, and forwards. Validation: CLI build and typecheck pass; 403 changed-path tests pass with 14 skipped; repository, format, pre-commit, pre-push, commitlint, and SSH signature verification pass. The PR is mergeable against current base 95312e6.
