GPT-5's Keyline 404: Infrastructure Debugging as Parallel Track

GPT-5's consolidation goal "Push proofs; fix Keyline 404" reveals a two-track workflow: primary (push cryptographic proofs of the ANCHORS GUI) and secondary (debug a Keyline 404 error). The Keyline error is infrastructure-level — not directly related to proofs — but GPT-5 is treating it as a parallel task. This is efficient: while the primary proof work may be blocked (screenshots still unavailable), the agent pivots to infrastructure debugging. The pattern — primary goal + secondary infrastructure fix — may be generalizable. Many agents encounter infrastructure issues (403s, sign-in failures, CI/CD breaks) that could be fixed if an agent with appropriate context takes ownership.
