PROOF OF EXIT
When a maze shows two doors, do they really represent two independent chances? A 4×4 maze, one real completed Atlas graph-v1 job, one exhaustive classical proof — and an honest mismatch between what was requested and what the engine returned.REQUESTED vs OBSERVED
Why intuition fails
ASSUMPTION ≠ VISUAL FACT▚ THE COMFORTABLE ANSWER
For two independent doors that each open with probability ½, the chance that at least one opens is ¾. Familiar, tidy — and completely reliant on an assumption the picture does not prove.
▚ WHAT THE MAZE ACTUALLY ENCODES
Under this maze's ideal corridor constraints, the two bridge doors must agree — they open and close together. Exhaustive classical proof checked all 65,536 sixteen-bit worlds: four satisfy the ideal constraints, and none has exactly one open bridge.
▚ THREE NUMBERS, THREE DIFFERENT STORIES
▚ THE PROBABILITY DIAGNOSTIC
| INDEPENDENT INTUITION | BALANCED TARGET | OBSERVED EMULATION | |
|---|---|---|---|
| ESCAPE PROBABILITY | 75% | 50% | 100.0% |
| UNDERLYING MODEL | naive assumption | ideal dependent | real Aer emulation |
| BRIDGE LOGIC | independent variables | correlated · ZZ=0 target | perfect agreement · ZZ=1 actual |
| RESULTING WORLD | theoretical | 4 valid 16-bit states | 0000000000000000 only |
The real Atlas job
NOT A MOCK RESULT▚ WHAT CAME BACK
The completed job returned 0000000000000000 in all 4,096 shots. That world has a certified path to the exit, so the observed escape fraction is 100%. Tomography reports ZZ = 1 on both bridge edges — the requested zero bridge correlations were not reached. The reason for the mismatch is unresolved; the request, status and raw result are preserved below, unedited.
The conditional finite theorem still holds: when all non-bridge equality constraints hold, the bridge doors agree. The all-zero world satisfies them. Endianness can't change this run's certificate — every returned bit is zero.
The mismatch is the result
REQUESTED ≠ OBSERVEDThe intended 50% balanced-bridge target was not realised — and the page says so in the open. Quantum outputs must be validated, not interpreted from intent alone.

▚ WHY A CERTIFICATE?
Every sampled world receives a deterministic path or sealed-region certificate — classical reachability over the returned bits. The engine proposes; classical logic disposes. Readers can tell apart three different things: the intended model, the actual engine output, and the classical explanation of what it means.
What is quantum here?
HONEST LIMITATIONSThe completed Atlas graph-v1 job used mode emu, backend aer — quantum-circuit emulation on a classical simulator, no physical QPU. The returned distribution is real Atlas job evidence; the finite proof and path certificates are classical. This demo does not claim quantum advantage or experimental confirmation of the balanced 50% target.
What survives the honesty cut: a graph engine asked to prepare a 16-qubit state whose measured edges match requested Pauli expectations, a real job lifecycle with saved request / status / raw JSON, and a lesson in dependence — the same reason quantum correlation is not just "two independent chances" either. That is the real teaching core: probability you can see.
