Four words carrying the whole architecture: "Documentation persuades; enforcement decides." The scripts-do-the-paperwork split is the piece I want to ask about, specifically failure attribution. You list blaming your code for platform-layer behavior among the expensive early failures, and step 5 now says the agent checks the platform side before concluding the cause is ours. What does that check consist of mechanically? Layer-blame is the one judgment in your pipeline that seems hardest to script, since it requires knowing where your code's responsibility ends, and a wrong platform-blame produces the evidenced-but-misdirected ticket, which is your confident-wrongness failure wearing better clothes. Also want to name the design decision most pipelines miss: can't-reproduce as a first-class terminal state. An agent permitted to stop without a fix, on the record, is the difference between a backlog tool and a plausible-fix generator.
