 ## Recent Changes
 
-- **Crate consolidation (13 → 9):** `rustapi-testing`, `rustapi-jobs`, `rustapi-view`, and `rustapi-toon` merged into `rustapi-core` and `rustapi-extras` as feature-gated modules.
-- **Embedded Isometric System Dashboard:** Live `/dashboard` with bento-grid layout, execution-flow visualization, and time-travel replay browser.
-- **Native MCP (full featured):** In-process invocation (~28µs per call), `cargo rustapi mcp generate` for any OpenAPI spec, stdio transport, and improved cookbook coverage.
-- Dual-stack runtime: simultaneous HTTP/1.1 (TCP) and HTTP/3 (QUIC/UDP)
-- WebSocket permessage-deflate compression
-- `rustapi-grpc` crate: optional Tonic/Prost-based gRPC alongside HTTP (`run_rustapi_and_grpc`)

-## Roadmap — v0.1.507 (shipped June 2026)
+- **Maintainability (#201):** `app/builder.rs` split into `routing`, `openapi`, `health`, and `run` modules; all `src/**/*.rs` under 50KB
+- **Run lifecycle:** consistent `on_shutdown` hooks across all `run*` entrypoints
+- **RustAPI Cloud CLI** (`cargo rustapi login`, `deploy cloud`) in v0.1.528
+- **Native MCP:** in-process tools, `cargo rustapi mcp generate`, stdio transport
+- **Embedded dashboard** with replay browser and execution-path visualization
 
-- [x] Embedded Isometric System Dashboard (`/dashboard`)
-  - Built-in control plane that boots automatically with a bento-grid layout, dark mode, and glassmorphism styling.
-  - Live architectural view of request routing across the **Ultra Fast**, **Fast**, and **Full** execution paths.
-  - Interactive endpoint visualization for topology inspection, route grouping, and runtime status awareness.
-  - Time-travel replay UI for browsing recorded HTTP traffic, selecting a historical request, and inspecting replay state directly from the dashboard.
-- [x] Native MCP (Model Context Protocol) Orchestration
-  - Embedded MCP server + `rustapi mcp generate` CLI turns any OpenAPI 3.x spec into agent tools.
-  - In-process invocation path: ~28 µs per call (vs ~1.3 ms for localhost proxy with live server) for 1000 sequential calls.
-  - stdio transport for desktop clients (Claude Desktop etc.).
-  - Tag/path-prefix filtering, full pipeline respect (or zero-copy in-process when co-located).
-  - Cookbook recipes for native use, CLI generator, in-process mode, and stdio.

+| App modules | `routing`, `openapi`, `health`, `run` — all `src/**/*.rs` under 50KB |
+| Run lifecycle | `on_shutdown` hooks run consistently on every `run*` entrypoint |
+| Tests | Router/extract bodies in `tests/support/*_lib.rs` via `include!` |
+| Public API | No breaking changes; `api/public` snapshots unchanged |
