Result description

Synthetic but arithmetically consistent demonstration result.

Outcome accounting

Successful shots
98,800
Logical-failure shots
1,000
Timeout shots
150
Decoder-error shots
50
Total shots
100,000

Arithmetic check: 98,800 successful + 1,000 logical failure + 150 timeout + 50 decoder error = 100,000 = 100,000 total shots.
