# R06 — paired native runtime transcript

Real commit -a holds index.lock in a cooperative pre-commit hook; timeout and interruption; subsequent real commit.

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
{
  "variants": [
    "timeout 1000ms",
    "interrupt with timeout null"
  ],
  "command": "commit -a -m controlled hook",
  "file": "tracked, edited",
  "hook": "pre-commit; cooperative TERM exit1; naturalCompletion 8000ms",
  "action": "observe actual .git/index.lock before cancellation, after return; disable hook; commit again"
}
```

| Variant | Before 30eb7e7bb1 | After 3c6d27fa7c |
|---|---|---|
| timeout | index.lock 1→0; timeout 1019.262ms; post-READY through subsequent commit 978.6ms; subsequent commit success=True; remaining locks=[], live 0 | index.lock 1→0; timeout 1014.716ms; post-READY through subsequent commit 969.9ms; subsequent commit success=True; remaining locks=[], live 0 |
| interrupt | index.lock 1→0; interrupted; post-READY through subsequent commit 32.1ms; subsequent commit success=True; remaining locks=[], live 0 | index.lock 1→0; interrupted; post-READY through subsequent commit 37.1ms; subsequent commit success=True; remaining locks=[], live 0 |
