+This is one of four homes, and the narrowest. Anything an agent can read out of
+`app/` stays in the code; a claim a wrong change could silently break belongs in
+an `INVARIANT:`-marked test; a rejected alternative, with the reasoning that
+would otherwise be re-litigated, is an ADR here; real work that is not scheduled
+is a GitHub issue. [`../../AGENTS.md`](../../AGENTS.md#workflow) defines the
+last two.
