Summary

Deep Agents Code lost the onboard-selected upstream provider when OpenShell removed the ambient environment value, so its UI reported the wire provider openai. Persist the selected provider in a root-owned, read-only file and restore it at the managed DCode entrypoint while keeping inference routing and credentials unchanged.

Related Issue

Fixes #7112

Changes

  • Materialize the onboard-selected upstream provider as a root-owned, mode 0444 managed-image file.
  • Replace ambient NEMOCLAW_UPSTREAM_PROVIDER at DCode startup with the validated managed value; fail closed when the file is missing or invalid.
  • Cover hostile ambient input, missing and unsafe managed input, exact image ownership/mode, and the status bar, welcome banner, and model-identity surfaces from the installed DCode package.
  • Validate DCode provider identifiers before materialization so the startup profile and installed runtime share the same 1-64-character ASCII contract.

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:
  • Docs updated for user-facing behavior changes
  • Docs not applicable — existing DCode guides already require runtime identity to match the selected provider and model and explain that older sandboxes require a rebuild
  • 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: Codex Desktop independently reviewed commit 8fea9f101; all nine security categories passed. The latest merge incorporates main at 5b1cf3ac4; the reviewed DCode validator behavior and PR-owned validator files are unchanged.
  • Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Documentation Writer Review

  • Documentation writer subagent reviewed the completed changes
  • Result: no-docs-needed
  • Evidence: Commit 8fea9f101 retains the reviewed DCode provider-identity contract, legacy staged-image validation, and emitted CommonJS validator import. The latest merge incorporates main at 5b1cf3ac4; the PR-owned validator files are unchanged from reviewed commit 687b02c48. Existing Deep Agents documentation already states that runtime identity reports the upstream provider selected during onboarding, the OpenAI-compatible adapter remains internal, and older sandboxes require a rebuild. No command, flag, default, public configuration schema, or supported workflow changed. Validation passed: the existing fixture integration test passed 10/10; the earlier reviewed change also passed 86 CLI tests, 6 integration tests, npm run build:cli, npm run typecheck:cli, npm run checks:repository, and git diff --check.

  • Targeted behavior tests pass for the current change set, or tests are marked not applicable above — 219 passed, 1 skipped across the complete DCode-focused profile, mapper, installed-runtime, package, and image suite; npm run build:cli and npm run typecheck:cli also passed
  • Applicable broad gate passed — npm run test:changed completed with 3,945 passing tests and 18 unrelated macOS uninstall failures: four gateway-scan exit-code assertions and fourteen watcher/report timeouts

Fresh macOS arm64 functional validation built and onboarded a DCode v0.1.34 sandbox from the v0.0.109-based branch. The actual TUI status bar rendered ollama-local:nemotron-3-nano:4b; exact-package probes reported ollama-local in the status bar, welcome banner, and model identity. Raw sandbox execution did not receive the provider environment value, and the managed provider file was root:root mode 0444. A local ignored build artifact extended the gateway-observation window from 30 to 120 seconds after OpenShell took about 42 seconds; no tracked source used that test-harness adjustment.

📝 Walkthrough

Walkthrough

DCode now stores NEMOCLAW_UPSTREAM_PROVIDER in a root-owned, read-only file. Onboarding validates the provider identifier before materialization. Runtime validation reads the file and exports the value for DCode. Tests cover precedence, metadata, runtime omission, and invalid file states.

Changes

Managed upstream provider

Layer / File(s) Summary
Provider file material
src/lib/onboard/managed-startup/agent-environment.ts, agents/langchain-deepagents-code/Dockerfile
Startup material and the Docker image create /usr/local/share/nemoclaw/dcode-upstream-provider. DCode removes this value from its long-running environment mapping.
Provider identifier validation
src/lib/onboard/managed-startup/dcode-upstream-provider.ts, src/lib/onboard/managed-startup/profile.ts, src/lib/onboard/dockerfile-patch.ts
DCode validates upstream-provider identifiers against a 1–64 character format before materialization or Dockerfile patching.
Provider loading and validation
agents/langchain-deepagents-code/managed-dcode-runtime.py
Runtime validation reads the managed provider file, validates its value, and sets NEMOCLAW_UPSTREAM_PROVIDER before configuring runtime state.
Provider precedence and file validation tests
test/helpers/langchain-deepagents-code-patch-fixture.ts, test/langchain-deepagents-code-provider-label.test.ts, src/lib/onboard/managed-startup-agent-environment.test.ts, test/langchain-deepagents-code-auto-approval-image.test.ts, src/lib/onboard/sandbox-dockerfile-patch-fail-closed.test.ts
Fixtures and tests verify file precedence, root ownership, read-only permissions, runtime omission, identifier validation, and rejection of missing, symlinked, writable, or malformed files.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 13eda

The PR restores the selected provider identity while leaving inference routing and credentials unchanged. The remaining risk is limited to two minor validation gaps around malformed provider names and replacing an existing fallback declaration, so it is mergeable with explicit owner awareness or follow-up.

Use a package-contract behavior test.

This assertion locks an exact Dockerfile string instead of a completed-image result. It does not prove provider-file metadata or runtime precedence. Move this coverage to test/package-contract/ and assert the public runtime behavior with a conflicting ambient provider.

As per coding guidelines, “Put genuine compiled-artifact assertions under test/package-contract/.” As per path instructions, tests must prefer “observable outcomes through the public boundary” over “source-text” assertions.

At commit c7fa37f, the managed startup profile validates the DCode provider identifier, but the legacy Dockerfile patch path does not. patchStagedDockerfile still passes NEMOCLAW_UPSTREAM_PROVIDER through sanitizeDockerArg, which removes CR and LF but does not enforce the DCode provider contract. That path can therefore bake an invalid provider into the protected file and defer the failure until runtime.

Apply the same provider validator before the legacy image build, including its fallback input, and add public-boundary coverage for the affected lifecycle path. The fresh DCode v0.1.34 reproduction and functional validation in the PR description resolve the earlier scope-evidence concern; this validation gap is the remaining blocking finding from my complete diff and sensitive-path review.

At the latest PR commit 41e0c2d, the original legacy-provider validation blocker is resolved, but current CI exposes a new blocking regression.

src/lib/onboard/managed-startup/profile.ts now imports ./dcode-upstream-provider without an extension. The checked-in scripts/checks/generate-managed-startup-profile-fixture.mts entry point executes the TypeScript source directly with node --experimental-strip-types. Node cannot resolve that extensionless source import, so test/generate-managed-startup-profile-fixture.test.ts fails with ERR_MODULE_NOT_FOUND and the aggregate CLI gate fails.

Keep one provider validator, but place it behind a module boundary that works for both the compiled CLI and the direct strip-types entry point. For example, keep and export the validator from profile.ts and import it from the Dockerfile patch path, or use another repository-supported boundary proven by the fixture test. Rerun the failing fixture, required CI, and the documentation receipt for the final commit before approval.
