| Feed-rate state | `SET_FEED_RATE` updates standalone canonical runtime state so vendored `convert_length_units()` can read it back through `GET_EXTERNAL_FEED_RATE()` during G20/G21 changes. |
| Tool-data reload | LinuxCNC `RELOAD_TOOLDATA` is captured as a canonical test event; browser/native tool-table reload plumbing remains a future host/runtime adapter. |
| Tool table storage | Vendored LinuxCNC `tooldata_common.cc` owns tool-table parsing and formatting; the standalone boundary only supplies the in-memory `tooldata_get()`/`tooldata_put()` callbacks, exposes load/save through the WASM C ABI, and forwards the host random-toolchanger flag to LinuxCNC `tooldata_init()`. |
| Tool slot status | Standalone tool adapter state supplies `GET_EXTERNAL_TOOL_SLOT()` and `GET_EXTERNAL_SELECTED_TOOL_SLOT()` for vendored `Interp::synch()`; `linuxcnc_interp_init_harness` guards current/selected slot synchronization. |
| Tool slot status | Standalone tool adapter state supplies `GET_EXTERNAL_TOOL_SLOT()` and `GET_EXTERNAL_SELECTED_TOOL_SLOT()` for vendored `Interp::synch()`; `linuxcnc_interp_init_harness` plus Node WASM and browser interpreter smokes guard current/selected slot synchronization. |
| Interpreter state tags | LinuxCNC `UPDATE_TAG` callbacks are captured from the state tags packed by vendored interpreter code; standalone code does not derive modal state. |
| Rotary indexer lock state | LinuxCNC `UNLOCK_ROTARY` and `LOCK_ROTARY` callbacks are captured from the vendored single-axis indexer path; standalone code does not implement rotary-indexing semantics. |
| File flush | LinuxCNC `FINISH` is captured as a canonical test event on the vendored `%`-delimited file-reading path. |
| WASM parameter-file backup | LinuxCNC `save_parameters()` calls `link()` to create the `.bak` parameter-file backup; `runtime/core/linuxcnc_wrap/linuxcnc_wasm_posix_stubs.cpp` maps that WASM/MEMFS edge to a file copy so the vendored save path can run unchanged. |
| Interpreter reset | LinuxCNC `ON_RESET` is captured as a canonical test event on the vendored interpreter reset/file-open path. |
| Interpreter init | LinuxCNC `INIT_CANON` and the canonical initialization sequence from vendored `Interp::init()` are captured as test events. |
| Interpreter init | LinuxCNC `INIT_CANON` and the canonical initialization sequence from vendored `Interp::init()` are captured as test events in native, Node WASM, and browser interpreter validation. |
| Comment logging | LinuxCNC `LOGOPEN`, `LOG`, `LOGAPPEND`, and `LOGCLOSE` callbacks are captured as canonical test events instead of writing host log files. |
| EMC status machine units | A narrow standalone `emcStatus` shim exposes the machine-units field used by vendored interpreter conversion and initialization code; `linuxcnc_emc_status_probe` and `linuxcnc_interp_init_harness` guard the inch/mm boundary. |
| EMC status machine units | A narrow standalone `emcStatus` shim exposes the machine-units field used by vendored interpreter conversion and initialization code; `linuxcnc_emc_status_probe`, `linuxcnc_interp_init_harness`, and the interpreter WASM/browser init probe guard the inch/mm boundary. |
| Python/remap | Python/remap hooks are stubbed at the runtime edge. |
| Dynamic interpreter path | `interp_base.cc` probe uses standalone `EMC2_HOME` compile-time path boundary. |
| Realtime scheduler | TP probes seed deterministic status/config data instead of running LinuxCNC realtime process topology. |
