 ### HTTP route boundaries
 
-Every file in `src/server/routes/` uses hono-openapi with zod validators for
-route inputs/outputs. Migrating these individually is the last step; most
-will switch to `.zod` derived from the Schema-migrated domain types above,
-which means touching them is largely mechanical once the domain side is
-done.
+The server route tree now lives under `src/server/routes/instance/httpapi` and
+uses Effect HttpApi contracts for request and response schemas. Remaining schema
+work is no longer a Hono route migration; it is compatibility cleanup around
+derived `.zod` statics, OpenAPI translation shims, and route groups that still
+need explicit SDK-visible error contracts.

+Good follow-up targets:
 
-The bigger prize for this group is the `@effect/platform` HTTP migration
-described in `specs/effect/http-api.md`. Once that lands, every one of
-these files changes shape entirely (`HttpApi.endpoint(...)` and friends),
-so the Schema-first domain types become a prerequisite rather than a
-sibling task.
+- shrink `public.ts` legacy OpenAPI translation shims one SDK-compatible slice at a time
+- replace production `.zod.safeParse(...)` call sites with Effect Schema decoders
+- remove derived `.zod` statics after their production consumers are gone
+- declare route-group errors directly instead of relying on compatibility middleware
