wt e4672fba91 S00-011: Verify public npm access and exact-version tarball integrity
Changes: Add a scoped fresh-cache registry probe, safe reproduction instructions and artifact ignore rule; record actual TLS-enabled metadata/download results and review handoff without selecting a stack or changing the harness.
Validation: Original npm view command and verify.py returned exit 0; react@19.3.1 tarball (26394 bytes) matched registry SHA-512. make check passed validation and 66 tooling tests. git diff --check passed. App install/build and different-harness connectivity remain unverified.

Task: S00-011
Agent: auto-ci-cd-d105e8027730
Role: ci-cd
Action: claim
Status: review
