How the run ended
Finished cleanly: a passing video with a synthesised soundtrack, three full final renders and a detailed, candid report. Also the most expensive run.

Judges’ notes
- AnthropicBest overall: detailed cathedral, gardens, dome, statued bridge and towers, clean chase framing and a strong finale.
- OpenAIDetailed Gothic facades, varied streets, convincing lighting and consistently readable framing make the strongest presentation.
- GoogleDetailed Gothic St. Vitus and dense baroque facades with a clear chase drone, marred only slightly by partial tower-pier framing at the bridge gate.

From the agent’s report
Short, verbatim quotes from the REPORT.md the agent wrote itself.
With that limit alone the fastest possible flight takes 49.6 s, more than the 46.5 s available.
St Vitus is modelled in full (nave, transept, chevet with buttresses, three towers) but only its south side is seen close up, and it reads as rather plain brown masonry.
