Two gaps the first post-migration decoder iteration exposed, both in the same
place — the loop ends before it can observe its own result.
1. Step 1 read notifications but never looked at the agent's own open PRs. It
opened #23, labelled the issue `state/needs-human`, and stopped; nothing in
the brief would ever bring it back to a red check. Next iteration it planned
to start a new question on top.
2. It called the merge resolved on `cargo build -p sylpheed-cli` — the crate the
conflict was in. The break was in `sylpheed-viewer`, which neither side of
the merge edited: one branch added a `ComposeOptions` field, the other had a
literal construction of it. The crate you just fixed is the one place the
breakage cannot be.
