# Decision Gate

Verdict: **GO**

```
VERDICT: GO
```

### Rationale
All four personas (Andrej Karpathy, Linus Torvalds, Staff Security Engineer, Principal Systems Engineer) unanimously approved the implementation in Round 2 reviews. All 6 functional requirements from the PRD are fully implemented, and the 1,287 test suite passes with 72 new tests covering critical edge cases including callback exception handling, out-of-order completions, and ANSI injection attacks. The only issues identified are MEDIUM/LOW severity cosmetic and documentation concerns—no CRITICAL or HIGH findings exist.

### Unresolved Issues
- None blocking. Minor cosmetic issues (TTY clear-to-EOL, global elapsed time, docstring clarity) do not affect correctness or reliability.

### Recommendation
**Merge as-is.** The implementation demonstrates production-grade engineering: proper exception isolation, defense-in-depth sanitization, backward-compatible API design, and comprehensive test coverage. The minor cosmetic issues identified (TTY line clearing, per-reviewer elapsed time tracking) can be addressed in follow-up PRs if users report visual artifacts.
