Summary

  • read public pull-request metadata without sending the workflow token
  • preserve open-state, repository, branch, head/base SHA, and NVIDIA-organization checks before and after checkout
  • enforce the least-privilege metadata contract with deterministic success, denied-response, and malformed-response tests

Why

The repository workflow token now receives HTTP 403 when the trusted manual E2E controller reads GET /repos/NVIDIA/NemoClaw/pulls/{number}. Because pull-request metadata for this public repository is itself public, sending that under-scoped token makes a permitted read fail. This keeps the existing identity checks but removes the unusable credential from both metadata reads; it does not add workflow permissions or expose secrets to candidate code.

Validation

  • npm exec vitest run -- test/e2e/support/e2e-public-pr-metadata.test.ts test/e2e/support/e2e-operations-workflow-boundary.test.ts test/automation/pull-requests/growth-guardrails.test.ts (111 passed)
  • npm run build:cli
  • npm run typecheck
  • npm run checks:repository
  • npm run validate:pr
  • cache-free public API probe against PR fix(onboard): exclude inactive OpenClaw messaging presets #10359 verified exact state, head repository/SHA, and base repository/ref/SHA

Limit

A fresh trusted exact-branch E2E dispatch remains the required hosted proof that matrix generation is reached. This PR does not rerun candidate E2E or broaden credential access.

Addresses #10360.

Summary by CodeRabbit

  • Security

    • Manual pull request authentication and checkout validation now use public, read-only metadata without workflow tokens or authorization headers.
    • Validation rejects inherited, step-level, and case-insensitive token-based authentication.
    • Checks fail closed when metadata is denied or malformed, improving protection against unauthorized access.
  • Tests

    • Added end-to-end coverage for secure metadata handling, process execution, and unauthorized token usage detection.

📝 Walkthrough

Walkthrough

The workflow now uses unauthenticated GitHub PR metadata requests. Boundary validation rejects token bindings and authorization headers. End-to-end tests cover inherited tokens, header casing variants, process failures, and malformed metadata.

Changes

Public PR metadata authentication

Layer / File(s) Summary
Enforce public metadata boundaries
tools/e2e/operations-workflow-boundary.mts
Manual PR authentication and checkout validation reject inherited or step-level GITHUB_TOKEN bindings and case-insensitive Authorization: headers.
Remove workflow credentials
.github/workflows/e2e.yaml
Manual PR authorization and checkout validation no longer pass workflow tokens or authorization headers to GitHub API requests. PR identity and ownership checks remain.
Test authentication behavior
test/e2e/support/e2e-public-pr-metadata.test.ts
Tests validate a restricted authentication environment and detect credential violations, header casing variants, inherited tokens, process failures, and malformed metadata responses.

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

Merge Risk: 🔵 Low · up to 25ab8

The workflow now reads public pull-request metadata without sending the workflow token while preserving the existing identity checks. The remaining concern is that the new metadata tests invoke child processes directly instead of the repository’s standard progress-aware subprocess utility; this is a bounded test-harness follow-up, so the PR is mergeable with owner awareness.

59-70: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Exercise both metadata requests in the terminal-response cases.

The workflow has separate Authenticate manual PR dispatch and Validate manual PR checkout steps. These cases execute only authentication.run. A curl failure or malformed response in validation.run can therefore regress without failing this test. Iterate over both run values or add equivalent cases for validation.run.

non-null assertions.
- Around line 13-16: Update authenticationEnvironment() to construct a

the fixture variables required by the test and PATH, while preserving the
existing BASE_SHA and related values.

- Around line 331-333: Update both manual PR authentication checks in the
workflow boundary scripts to detect Authorization headers case-insensitively,
allowing optional whitespace before the colon, using the pattern
\bauthorization\s*:. Add a regression test covering a lowercase authorization
header while preserving the existing rejection behavior.
- Around line 331-333: Update validateManualPrDispatch to inspect workflow-level
and generate-matrix job-level GITHUB_TOKEN bindings in addition to step-level
authentication.env, rejecting any inherited binding while preserving the
existing Authorization-header check. Add regression cases covering both
inherited scopes.

104-121: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Bound the synchronous workflow probe.

Keep spawnSync, but add a positive timeout shorter than the first E2E heartbeat and killSignal: "SIGKILL". Without these options, a hung workflow command can block the e2e-support Vitest process.

✨ Thanks for the fix. This restores the manual PR dispatch authentication by removing the unusable workflow token from public metadata reads while preserving the existing identity checks.
