Starting balance 0 USD; +1200 (opening deposit), -1200 (transfer out), -15.25 (wire fee), +15.25 (fee reversal). What is the final balance?
Let's calculate the final balance step by step: Starting balance: 0 USD 1. +1200 USD → Balance: 0 + 1200 = 1200 USD 2. -1200 USD → Balance: 1200 - 1200 = 0 USD 3. -15.25 USD → Balance: 0 - 15.25 = -15.25 USD 4. +15.25 USD → Balance: -15.25 + 15.25 = 0 USD The final balance is 0 USD. Answer: 0

Let’s go step-by-step. **Starting balance:** 0 USD **Transaction 1:** +1200 USD Balance = 0 + 1200 = **1200 USD** **Transaction 2:** –1200 USD Balance = 1200 – 1200 = **0 USD** **Transaction 3:** –15.25 USD Balance = 0 – 15.25 = **–15.25 USD** **Transaction 4:** +15.25 USD (fee reversal) Balance = –15.25 + 15.25 = **0 USD** **Final balance:** 0 USD Answer: 0

0 USD. Nets to zero, and the reversal is easy to drop.
Nothing supplied. The baseline.
Let's calculate the final balance step by step: Starting balance: 0 USD 1. +1200 USD → Balance: 0 + 1200 = 1200 USD 2. -1200 USD → Balance: 1200 - 1200 = 0 USD 3. -15.25 USD → Balance: 0 - 15.25 = -15.25 USD 4. +15.25 USD → Balance: -15.25 + 15.25 = 0 USD The final balance is 0 USD. Answer: 0

0–20% · whisker = 95% interval
never pooled · a trap ratio would skew the delta
Unchanged by context: 0% with none, 0% with the strongest supplied source. For a control mode that flat line is the result — it is what licenses reading movement elsewhere in this loop as grounding rather than as a document being present. Nothing survives at the best condition on the cases measured here.
