# R04 — paired native runtime transcript

31,000ms actual timeout on a 40,000ms hostile alias; concurrent short pooled probe.

Steps: create a fresh synthetic committed repo; start real GitVcsDriver operations; await fixture READY (and ninth REQUEST where applicable); apply the scripted timeout/interruption/control; observe command return, actual signals, process liveness and marker checkpoints. Events use monotonic ms from each printed wall origin.

Inputs from the exact uploaded driver (these are setup values, not inferred outcomes):

```json
{
  "timeoutMs": 31000,
  "naturalCompletionMs": 40000,
  "signalPolicy": "ignore TERM",
  "concurrentProbe": "rev-parse HEAD; pooled default"
}
```

| Variant | Before 30eb7e7bb1 | After 3c6d27fa7c |
|---|---|---|
| 31000 | timeout 40059.2ms, Git command timed out.; pooled probe 8.8ms; markers 1, live 0 | timeout 32020.2ms, Git command timed out.; pooled probe 10.3ms; markers 0, live 0 |
