 ## Dialect expansion
 
 LinuxCNC support should be the baseline. Fanuc and Siemens support should be implemented as dialect adapters, not by forking the simulator core.

+- `build-wasm.sh` keeps fixed artifact paths: CMake writes `build/wasm`, then
+  the script copies and byte-compares `cnc_sim.js` and `cnc_sim.wasm` under
+  `web/public` before running Node and browser smoke checks.
+
+Build and source-link guardrails:
+
+- `CNC_SIM_BUILD_JOBS` must be a positive integer and defaults to `8`.
+- `test-native.sh` uses persistent `build/native-test` objects, dependency
+  files, and `native-build.signature`.
+- `test-linuxcnc-source-link.sh` uses persistent `build/source-link-test`
+  objects, dependency files, and `source-link-build.signature`.
+- `test-linuxcnc-source-syntax.sh` uses persistent
+  `build/source-syntax-test` stamps, dependency files, and
+  `source-syntax.signature`.
+- `test-linuxcnc-wasm-cmake-safe-probe.sh` uses persistent
+  `build/wasm-cmake-safe-probe` and `wasm-cmake-safe-probe.signature`.
+- Native, source-link, source-syntax, wasm-safe CMake probe, and build-wasm
+  paths must reject empty, whitespace-containing, or filesystem-root build
+  directory overrides before doing destructive cleanup.
+- Native, source-link, source-syntax, and build-wasm entry points must serialize
+  shared non-concurrency-safe paths with lock files before writing fixed
+  outputs.
+- Source-link and syntax probes must build from generated makefiles with
+  `-MMD -MP` dependency tracking and `make --output-sync=target`.
+- `build-wasm.sh` must run blocker, syntax, object, CMake, tooldata,
+  `interp_*`, Python, `rs274ngc_pre`, and runtime link probes before copying
+  browser artifacts.
+- `build-wasm.sh` must check `cmake`, `emcmake`, `emcc`, and `node` before the
+  Emscripten configure step.
+- `build-wasm.sh` must build `cnc_sim_wasm_runtime_probe` before
+  `cnc_sim_wasm`.
+- `build-wasm.sh` must copy `build/wasm/cnc_sim.js` and
+  `build/wasm/cnc_sim.wasm` exactly once each.
+- `build-wasm.sh` must compare copied artifacts with `cmp -s` before running
+  Node or browser smoke tests.
+- `build-wasm.sh` must run the Node smoke before the browser smoke.
+- The default wasm manifest partition must remain explicitly checked for 25
+  wasm-safe core sources and 9 blocked sources.
+- Manifest source listers must reject malformed lines, absolute source paths,
+  unknown groups, unknown filters, and duplicate source entries.
+- Native link flags must include the built LinuxCNC `lib` path and rpath.
+- Common CXX flag helpers must surface helper failures instead of hiding them
+  behind process substitution or `read`.
+- Temporary probe reports must be cleaned on failure and preserved only after a
+  successful report path explicitly opts in.
+- Documentation-only build policy edits should still update the guardrail
+  checks that enforce the relevant script and artifact ordering.
