 ## Current route files
 
-Current instance route files live under `src/server/routes/instance`.
-
-Files that are already mostly on the intended service-yielding shape:
-
-- [x] `server/routes/instance/question.ts` — handlers yield `Question.Service`
-- [x] `server/routes/instance/provider.ts` — handlers yield `Provider.Service`, `ProviderAuth.Service`, and `Config.Service`
-- [x] `server/routes/instance/permission.ts` — handlers yield `Permission.Service`
-- [x] `server/routes/instance/mcp.ts` — handlers mostly yield `MCP.Service`
-- [x] `server/routes/instance/pty.ts` — handlers yield `Pty.Service`
+Current instance route files live under `src/server/routes/instance/httpapi`.
+Most handlers already yield stable services at route-layer construction and then
+close over those services in endpoint implementations.
 
 Files still worth tracking here:
 
-- [ ] `server/routes/instance/session.ts` — still the heaviest mixed file; many handlers are composed, but the file still mixes patterns and has direct `Bus.publish(...)` / `Session.list(...)` usage
-- [ ] `server/routes/instance/index.ts` — mostly converted, but still has direct `Instance.dispose()` / `Instance.*` reads for `/instance/dispose` and `/path`
-- [ ] `server/routes/instance/file.ts` — most handlers yield services, but `/find` still passes `Instance.directory` directly into ripgrep and `/find/symbol` is still stubbed
-- [ ] `server/routes/instance/experimental.ts` — mixed state; many handlers are composed, but some still rely on `runRequest(...)` or direct `Instance.project` reads
-- [ ] `server/routes/instance/middleware.ts` — still enters the instance via `Instance.provide(...)`
-- [ ] `server/routes/global.ts` — still uses `Instance.disposeAll()` and remains partly outside the fully-composed style
+- [ ] `handlers/session.ts` — still the heaviest mixed file; some paths keep compatibility translations and direct event publication
+- [ ] `handlers/experimental.ts` — mixed state; some handlers still rely on request-local context reads
+- [ ] `middleware/*` — still contains compatibility policy for auth, compression, errors, instance context, and workspace routing
+- [ ] `public.ts` — still owns SDK/OpenAPI compatibility translation shims
+- [ ] raw route modules — WebSocket and catch-all routes should stay explicit and avoid rebuilding stable layers per request
 
 ## Notes
 
-- Route conversion is now less about facade removal and more about removing the remaining direct `Instance.*` reads, `Instance.provide(...)` boundaries, and small Promise-style bridges inside route files.
-- `jsonRequest(...)` / `runRequest(...)` already provide a good intermediate shape for many handlers. The remaining cleanup is mostly consistency work in the heavier files.
+- Route conversion is now less about backend migration and more about removing the remaining direct `Instance.*` reads, request-local service plumbing, and OpenAPI compatibility shims.
+- Prefer route-layer service capture over rebuilding or providing stable layers inside individual handlers.
