// If you add a `completeWaitpoint(` call site in the run-engine, add a matching
// entry here or `apps/webapp/test/crossSeamGuard.proof.test.ts` fails. Entries are
// one-per-textual-call-site (so the per-file count matches the source), anchored by
// method name, not line number. The `kind` is the dominant route kind — store
// selection is driven by residency, not kind, so a disputed kind label is cosmetic.
//
// PURE module — no engine import, no env, no Prisma.
