// CPE24-P3: legacy (port 57374) mappings for memory, context, focus and tasks. Each reads the same source as its /v1 route (routes/memory.ts)
// and keeps the legacy response shape. The shim's guard (legacyGuard) has already run; POST /api/focus adds the same loopback, JSON and Origin checks as /v1/focus.
