Phase 4 of the #513 roadmap: ESP-IDF component skeleton at `firmware/esp32-csi-node/components/ruv_temporal/`. Source is complete and self-consistent; cross-compile to xtensa-esp32s3-none-elf is blocked by a known-broken esp-rs nightly snapshot (details in the component README). What's in the scaffold: - `Cargo.toml` — staticlib, no_std + alloc, deps on the path-vendored `ruvllm_sparse_attention` (matching ADR-096's host-side dep) and `esp-alloc`/`critical-section` for the no_std allocator and lock primitives. - `src/lib.rs` — public C ABI (init / push / classify / destroy / self_test) with `#[no_mangle]` exports, a `[#used]` keepalive table to defeat aggressive linker stripping, esp-alloc as the global allocator (heap region added at runtime by the firmware), and a loop-on-panic handler (Phase 5 will route through esp_system_abort). - `src/window.rs` — `FrameRing`, the rolling-window buffer that `ruv_temporal_push` writes to. Chronological iteration via `iter_chronological()` so the kernel sees oldest-first. - `include/ruv_temporal.h` — the public C header consumed by edge_processing.c. Threading contract documented inline (single dedicated FreeRTOS task, no internal locks). - `CMakeLists.txt` — runs `cargo +esp build` as an ESP-IDF pre-component-register step, then registers the static library through `idf_component_register` + `target_link_libraries(... INTERFACE ...)`. `shim.c` exists only because `idf_component_register` requires SRCS. - `.cargo/config.toml` + `rust-toolchain.toml` — pin the build to `xtensa-esp32s3-none-elf` and the `esp` toolchain channel so `cargo build` without flags Just Works once the toolchain is unblocked. - `README.md` — Phase status table, Phase 5 toolchain blocker explanation, and the espup install fix. ABI calls into edge_processing.c (Phase 6) and COM8 validation (Phase 7) follow once the cross-compile is unblocked. Closes nothing yet; advances #513. Co-Authored-By: claude-flow <ruv@ruv.net>
