  "outcome": "One independently reviewed environment-access probe demonstrates authentic pinned Linux Node/npm and integrity-verified installation of the parent locked dependency graph without changing accepted stack or network security policy.",
  "steps": [
    "Read S00-003 blocker evidence and accepted stack pins.",
    "Obtain external approved HTTPS connectivity or authentic locally supplied pinned Linux runtime and locked dependency artifacts.",
    "Verify vendor checksum for runtime, exact node/npm versions, and lock integrity with a script confined to the remediation directory; install a copy of the parent manifest/lock only inside that directory.",
    "Document reproducible approved artifact paths or connectivity and actual results; submit for independent review."
  ],
  "acceptance": [
    "Node 24.21.0 and npm 11.19.0 execute on this Linux host with authenticated vendor checksum verification recorded.",
    "Copied unchanged parent package-lock installs successfully with package integrity enforced and Stanza 12.22.1 available.",
    "No stack/lock/spec changes, engine or TLS bypass, proxy policy bypass or secrets in evidence."
  ],
  "checks": [
    "Exact runtime version and official checksum comparison.",
    "Isolated npm ci of unchanged parent manifest/lock with lifecycle scripts disabled and TLS verification retained.",
    "Independent review repeats access/runtime/lock checks."
