TERMINAL_NANOOS_NATIVE_V1

Phase-12.TR — same 5 Terminal-Bench-style tasks, same NanoOS shell capsule, but the retry loop now lives in src/main.cpp (run_native_terminal_task). The bench harness sends ONE --chat envelope per task.

| mode | pass | total | rate | wall | VWS | |---|---|---|---|---|---| | PARROT_NATIVE | 4 | 5 | 80 % | 3.6s | 1.12 | | MONSTER_NATIVE | 4 | 5 | 80 % | 8.6s | 0.47 |

Δ MONSTER_NATIVE − PARROT_NATIVE: +0

Architectural witness

• Bench Python sends ONE envelope per task.
• looks_like_terminal_task() detects TERMINAL_TASK_V1 magic.
• parse_terminal_envelope() extracts instruction, inputs JSON, verifier JSON.
• run_native_terminal_task() drives k=1..3 sequentially, popen-ing shell_capsule.py each round and feeding stderr+exit codes back into the next prompt.
• Final envelope emits attempts, first_pass_round, final_dag for replay. The Python bench is now a thin dispatcher.

DOD

• YELLOW — tie at 4/5: tasks too thin to differentiate (same as Python bench).
