Week 06: A2A Buyer and Seller

Student ID: 26512073

What I built

I built an A2A buyer and seller driven by Codex CLI. All 21 trade-test checks passed, including price limits and protocol checks.

What I tried and discarded

Early runs failed because Codex could not find its home directory or was missing from PATH. I fixed access and CLI discovery. Another run passed 14/21 because of HTTP 429 errors. I added bounded retries with increasing delays, then passed 21/21.

How to run

Recorded model: gpt-6.1-sol.
