| [INSTRUMENT.md](INSTRUMENT.md) | Debugging/profiling tools in the Valgrind/callgrind/asan/ubsan tradition: the emulator as a dynamic-binary-instrumentation substrate (the `EmuToolHooks` ABI, shadow planes, the memory seam, a guest debugger), plus the cross-frontend compiler-sanitizer story. | [../EMU.md](../EMU.md) |
| [JIT.md](JIT.md) | Function-level hot reload, Go-runtime-style managed codegen support, and remaining JIT host-portability work. | [../JIT.md](../JIT.md) |
| [ARM32.md](ARM32.md) | 32-bit ARM (`arm-none-eabi`, ARMv7-M/ARMv7E-M Thumb-2, Cortex-M3/M4/M7) freestanding backend: Phase 1 (walking skeleton) is landed; Phase 2 tracks the remaining ops, the -O1 known-frame path, 64-bit, atomics, TLS, and the `qemu-system-arm` cross-test lane. | [../ARCH.md](../ARCH.md), [../PORT.md](../PORT.md) |
+| [MCU.md](MCU.md) | Microcontroller development workflow for STM32 Cortex-M (ARMv7-M/E-M) and Espressif RISC-V (ESP32-C/H/P): the last-mile gaps over the working backends — `objcopy` ihex/srec, reusable startup/vector-table + starter linker script, the rv32 soft-float-default footgun, SDK interop, and on-target debug. Assessment stage; references ARM32.md for ARM-core follow-ons. ARMv6-M/Cortex-M0 and Xtensa are out of scope. | [ARM32.md](ARM32.md), [../RUNTIME.md](../RUNTIME.md), [LINKER.md](LINKER.md) |
| [SYSROOTS.md](SYSROOTS.md) | Cross-compile sysroot packaging: minimal per-target stubs/headers/CRT objects distributed via `.kpkg` for the support set. Design complete, implementation not yet started. | — |
| [BUILD.md](BUILD.md) | A new content-addressed build coordinator (Bazel/Nix-style incremental builds layered on the CAS) — storage state machine, caching algorithm, recipe protocol. Design, not yet built. Distinct from `../BUILD.md` (kit's own Makefile build). | — (new subsystem) |
| [TODO.md](TODO.md) | Open deferred fixes and code smells, plus terse backlog folded from retired plan docs (arch-backend parity, Wasm object backend, Windows x64 self-host, bootstrap breadth). Completed items are removed instead of checked off. A current backlog, not a roadmap. | — |
