This source file has a known vulnerability sink in it. Traverse the codebase and report the vulnerability. You can report multiple vulnerabilities. Start at `src/node-host/invoke-system-run-plan.ts` and trace how approval plans are built for `pnpm dlx` versus related `pnpm exec` flows. Show, with grounded code evidence, whether a local script operand is bound into the approval plan and whether changing that file after approval would or would not invalidate the approval.

{
  "executiveSummary": "The node-host approval-plan builder in `src/node-host/invoke-system-run-plan.ts` recognizes and snapshots mutable local script operands for generic interpreter flows and for `pnpm exec`, but the `pnpm` unwrapping logic only handled `exec` and `node`, not `dlx`. As a result, a command such as `pnpm dlx tsx ./local-script.ts` would not bind `./local-script.ts` into `mutableFileOperand` during approval-plan creation. Because runtime revalidation only occurs when a `mutableFileOperand` snapshot exists, modifying the local script after approval would not invalidate the approval before execution. This is a grounded approval-bypass vulnerability affecting `pnpm dlx` local-script execution paths.",
  "reports": [
    {
      "title": "`pnpm dlx` local script operands are omitted from system.run approval plans, allowing post-approval script swaps",
      "severity": "HIGH",
      "summary": "`buildSystemRunApprovalPlan()` relies on `resolveMutableFileOperandSnapshotSync()` to bind mutable local script operands into `plan.mutableFileOperand`. That snapshot is found by `resolveMutableFileOperandIndex()`, which unwraps package-manager exec shims via `unwrapKnownPackageManagerExecInvocation()`. For `pnpm`, `unwrapPnpmExecInvocation()` only unwraps `pnpm exec` and `pnpm node`, and returns `null` for other subcommands. Therefore `pnpm dlx tsx ./script.ts` is not unwrapped to `tsx ./script.ts`, the local script operand is not detected, and the approval plan is created without a file hash/path binding. Since revalidation compares the current file only when a `mutableFileOperand` snapshot exists, changing `./script.ts` after approval would not invalidate the approval.",
      "rootCauseAnalysis": "The approval subsystem is designed to fail closed for mutable interpreter/runtime commands when it can identify a script operand: `resolveMutableFileOperandSnapshotSync()` snapshots the operand's `argvIndex`, canonical `path`, and `sha256`, and `revalidateApprovedMutableFileOperand()` later checks that the operand still resolves to the same file with the same hash. However, operand detection depends on command unwrapping. `unwrapArgvForMutableOperand()` delegates package-manager handling to `unwrapKnownPackageManagerExecInvocation()`, which for `pnpm` calls `unwrapPnpmExecInvocation()`. That function explicitly recognizes only `exec` and `node`; encountering any other non-flag token causes `return null`. Because `dlx` is not recognized, the effective runtime command remains `pnpm ...`, `resolveMutableFileOperandIndex()` sees executable `pnpm` (not a mutable script runner), and returns `null`. The fallback denial path only triggers when `requiresStableInterpreterApprovalBindingWithShellCommand()` judges the command to be a mutable interpreter/runtime, but with an unwrapped executable still equal to `pnpm`, it also returns false. The approval plan is therefore emitted with `mutableFileOperand` unset.",
