+manifest without browser directory enumeration. `planSimConfigStaging()` is the
+`configs/sim` wrapper around that generic planner. These planners are host
+filesystem helpers only; execution still goes through vendored LinuxCNC
+interpreter/remap/tool/parameter code.
+
+Layer responsibilities are intentionally narrow:
+
+| Layer | LinuxCNC-owned behavior | Host/WASM adapter allowance | Expected-failure policy |
+| --- | --- | --- | --- |
+| 1 | `nc_files` parsing and execution through upstream `rs274` | Generate only the native harness INI/tool-table context needed to classify upstream examples | Expected failures document missing machine/task context or known upstream example edges; they must not be made pass by changing G-code semantics. |
+| 2 | `configs/sim` file execution through upstream `rs274` with sim INI context | Locate the corresponding INI/tool table and classify main programs, macros, and remap subroutines | Expected failures document upstream standalone `rs274` limits such as task/user-M process edges and the preserved `incremental_repetition_g533.ngc` demo edge. |
+| 3 | Vendored LinuxCNC interpreter, remap, tool, parameter, kinematics, and planner code | Provide deterministic runtime shims for filesystem, HAL/user-M boundaries, machine status, and build/source-probe coverage | A standalone pass may cover a runtime edge that Layer 1/2 cannot provide, but it must still call vendored LinuxCNC source for CNC behavior. |
+| 4 | Vendored LinuxCNC C ABI behavior from generated WASM modules | Stage files, apply executable bits, persist OPFS text, generate manifest-based staging plans, and forward paths/results between JS/browser and C ABI | A WASM/browser pass proves the host boundary can reproduce the staged LinuxCNC context; it does not replace native source validation or justify JS-owned CNC semantics. |
+
+## Layer 2 Expected Failures
+
+The current `wasm-port/tests/native/verify_sim_configs.sh` run reports
+`total: 159`, `pass: 151`, `expected_fail: 8`, and `unexpected_fail: 0`.
+The eight expected failures are:
+
+| Program | Layer 2 classification | Current Layer 3/4 coverage or boundary |
+| --- | --- | --- |
+| `axis/foam/foam.ngc` | `ini-axis-mask-UV`; native upstream `bin/rs274` rejects `U`/`V` words before the standalone runtime applies the INI machine axis mask. | Covered by `wasm-port/tests/native/verify_native_probes.sh`, `wasm-port/tests/wasm/node/verify_sim_configs_wasm.sh`, and `wasm-port/tests/browser/verify_interp_browser.sh`, which run the vendored file with `axis_foam.ini` and verify `U/V` axis acceptance through LinuxCNC-backed file execution. |
+| `axis/vismach/5axis/bridgemill/5axisgui.ngc` | `ini-axis-mask-W`; native upstream `bin/rs274` rejects the `W` word outside the bridge-mill runtime context. | Covered by `wasm-port/tests/native/verify_native_probes.sh`, `wasm-port/tests/wasm/node/verify_sim_configs_wasm.sh`, and `wasm-port/tests/browser/verify_interp_browser.sh`, which stage `5axis.ini`, the tool table, and remap subroutines, then execute through the vendored LinuxCNC remap/file path. |

+| `axis/external_offsets/opa_demo.ngc` | `user-m-code-M111`; same standalone task/user-M boundary as `dyn_demo.ngc`, plus a subroutine dependency. | Covered by `wasm-port/tests/wasm/node/verify_sim_configs_wasm.sh` and `wasm-port/tests/browser/verify_interp_browser.sh`, which stage `M111`, `eoffset.tbl`, and the `SUBROUTINE_PATH` dependency `circles.ngc`. |
+| `axis/vismach/5axis/table-rotary_spindle-rotary-nutating/demos/incremental_repetition_g533.ngc` | `upstream-demo-missing-motion-gcode`; upstream standalone `rs274` reports `Cannot use axis values without a g code that uses them`. | Preserved as an upstream demo expected failure.

A representative vendored subset now passes Node WASM and browser execution through LinuxCNC-backed `Interp::open()`/`read()`/`execute()`, with `3D_Chips.ngc` using an INI-declared tool-table context for its upstream `T1 M6` line. |
