Summary

Managed llama.cpp lifecycle commands now reconstruct the same Docker authority after onboarding installs OpenShell in the user-local binary directory. A resumed onboarding or destroy command no longer rejects its own receipt only because the new process started with the pre-install PATH.

Related Issue

Fixes #9585

Changes

  • Reuse one executable-checked helper for the user-local OpenShell PATH adjustment made after installation.
  • Apply that adjustment to a copied managed llama.cpp operation environment before authority creation. The common operation factory is the current consumer because a resume-only change would leave status, doctor, and destroy with the same mismatch.
  • Add regression coverage for cross-process resume authority and for rejecting a non-executable user-local OpenShell path.

Type of Change

  • Code change (feature, bug fix, or refactor)
  • Code change with doc updates
  • Doc only (prose changes, no code sample modifications)
  • Doc only (includes code sample changes)

Quality Gates

  • Tests added or updated for changed behavior
  • Existing tests cover changed behavior — justification:
  • Tests not applicable — justification:
  • Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
  • Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: Reviewed the lifecycle-authority boundary. Docker executable, endpoint, full PATH, SSH helper, and credential-helper drift remain bound and fail closed; the negative regression test rejects a non-executable local OpenShell path.
  • Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Verification

  • Normal pre-commit, commit-msg, and pre-push hooks passed, or npm run validate:pr passed after refreshing origin/main when hooks were skipped or unavailable
  • Targeted behavior tests pass for the current change set, or tests are marked not applicable above — command/result or justification: npx vitest run --project cli --project integration src/lib/onboard/runtime-provider/docker-operation-authority.test.ts src/lib/onboard/openshell-install.test.ts test/onboard-openshell-install-stream.test.ts — 3 files and 30 tests passed.
  • Applicable broad gate passed — npm test for broad runtime/test-harness changes; npm run check for repo-wide validation/coverage changes — command/result:
  • Quality Gates section completed with required justifications or waivers
  • No secrets, API keys, or credentials committed
  • npm run docs builds without warnings (doc changes only)

📝 Walkthrough

Walkthrough

The change centralizes user-local OpenShell PATH preparation, reuses it after installation, and applies it during managed llama.cpp Docker authority creation. Tests cover resume behavior, invalid OpenShell paths, and host-local authority stability.

Changes

Managed llama.cpp resume path handling

Layer / File(s) Summary
OpenShell path remediation
src/lib/onboard/openshell-pin.ts
Adds prependInstalledUserLocalOpenshellPath and its dependency type. The helper accepts only regular executable files and updates PATH after validation. Post-install logic uses the helper.
Managed authority integration and validation
src/lib/onboard/runtime-provider/docker-llama-cpp-operation.ts, src/lib/onboard/runtime-provider/docker-operation-authority.test.ts
Managed llama.cpp authority creation uses a copied environment with the prepared user-local OpenShell path. Tests cover reduced-PATH resume behavior, invalid files and directories, and host-local authority stability.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 64b33

The PR preserves lifecycle authority across resumed llama.cpp operations, with targeted regression coverage passing. No actionable merge-blocking risk remains beyond normal checks and review.

Terminology decisions are advisory. They affect the assessment only when a separate finding identifies concrete semantic impact.

  • justified — authority at src/lib/onboard/runtime-provider/docker-llama-cpp-operation.ts:69: Retain the established term because the qualification boundary affects persisted runtime identity and command authorization.
  • established — user-local at src/lib/onboard/openshell-pin.ts:212: Retain the established term because installation location determines the PATH entry used during authority reconstruction.

Reviewed commit 6808ab6 against #9585 and base b7383ca.

  • Product scope: repairs the documented experimental managed llama.cpp resume and destroy contract; it creates no new supported surface.
  • Correctness and architecture: reconstructs the post-install user-local OpenShell PATH only in a copied managed llama.cpp operation environment before the common Docker authority factory runs. Status, recovery, and destroy share that factory; host-doctor and sandbox-lifecycle keep separate scopes.
  • Security: regular-file and executable checks reject invalid OpenShell paths, while Docker executable, endpoint, full PATH, delegated helpers, persisted authority, and binding checks remain fail closed.
  • Evidence: focused local Vitest run passed 3 files and 31 tests. Both CodeRabbit threads are resolved. The cross-issue sweep found no adjacent fix or contradiction.
  • Merge state: GitHub reports MERGEABLE, and all five required checks pass on the commit under review.

Reviewed commit 6808ab6. I found no critical blocker. The copied environment restores only a validated executable OpenShell path before constructing the common Docker authority, and the existing endpoint, executable, delegated-helper, binding, and ownership checks remain fail closed.
