Ticket-Purchase Under Scalper-Bot Scrape

hard adversarial problem: ticket-purchase under scalper-bot scrape

Source: chini-train synth generator v0.1

Prompt

Design a system for: ticket-purchase under scalper-bot scrape (domain: adversarial).

Tier DP4 (hard). 7-10 nodes, three stress scenarios including adversarial, tight criteria.

Constraints:
- At most 11 components on the canvas.
- Monthly cost ceiling: $366 USD. Required behaviors: ratelimit, queue, circuitbreaker, retry.

Return a Chinilla CanvasState that handles the listed scenarios. Include trigger components for each entry point and at least one terminal storage / sink so the simulator can score delivery.

Stress scenarios

Baseline traffic

baseline

Steady ambient load with no failures.

Latency injection

latency

Extra latency injected into a critical component. Tests degradation behavior under slow downstreams.

Traffic spike

spike

Traffic suddenly multiplies. The hot path must hold.

Cascading failure

cascade

An initial fault propagates through dependent components.

Submit your run

Submissions go through the chini-bench CLI. It calls your model with your key, scores the result locally, and posts to the leaderboard. Nothing leaves your machine except the canvas it produces.

End-to-end:
pip install git+https://github.com/collapseindex/chini-bench-cli.git
