`examples/<name>/` was a tested surface in name only. The source-quality job had no examples check at all, and scripts/smoke_examples.sh accepted any process that had not printed one of its error markers: a project that died during startup, exited after a single frame, or crashed without a marker was reported as PASS. Nothing stopped a malformed or unregistered example from reaching dev, which is how 14 examples arrived without READMEs and 20 were never registered in the overview table. Source side - scripts/check_examples.py classifies every directory under examples/ as either runnable (main.nut plus a config.nut that assigns the engine `config` table) or as a reviewed non-runnable sample listed in NON_RUNNABLE_EXAMPLES with a reason. Both kinds must own a README.md and appear in examples/README.md. Stale exemptions and overview links to missing directories fail as well. - `make check/examples` and a new source-quality CI step run the gate. - scripts/tests/test_check_examples.py covers it and pins each failure mode against fixtures. Runtime side - scripts/smoke_examples.sh now enforces liveness, not just marker absence: every runnable example must still be running after MIN_RUN_SECONDS (default 2s; CI passes 2s), and a process that dies inside that window fails whatever its exit code. A clean self-exit after the window passes with an explicit note instead of being silently accepted as a pass. - The Linux CI step sets MIN_RUN_SECONDS=2 and keeps RUN_SECONDS=6, so the job's wall clock is unchanged (13.7 min of its 20 min budget on dev). Windows / GBK - scripts/utf8_stdio.py re-encodes stdout/stderr as UTF-8 and every scripts/*.py program calls it as the first statement of its __main__ block. On a Chinese Windows a redirected stream falls back to the ANSI code page (cp936), and printing a character that code page cannot encode (arrows, superscripts, bullet separators, emoji - all common in this repository) raised UnicodeEncodeError and turned a checker into a traceback. - The mirror image is input: read_text() without encoding= decoded UTF-8 repository text as cp936 and raised UnicodeDecodeError. - scripts/tests/test_utf8_stdio.py enforces both conventions for every script and test module; text file I/O and child-process decoding now pass encoding="utf-8" explicitly. - Unit-test invocations run with `python3 -X utf8` so the runner's own output never follows the host code page. Violations the new gates found on top of dev, fixed here: 14 examples shipped without a README (fluid3d, mesh-impact-lab, mesh-modifier-lab, spline-tube-lab on the earlier dev tip, plus pcg-depth-of-field, pcg-detail-overwrite, pcg-layer-culling, pcg-location-system, pcg-runtime-orchestration, pcg-scene-player-culling, pcg-snow-wind, pcg-thunder-strike, pcg-ui-scaler and pcg-underwater added by #397), 20 were missing from the overview table (those 14 plus archspace-editor, geometry-stroke-lab, interior-mapping, layered-animation, triplanar-decal, terrain-stamping), and scripts/export_meshret_onnx.py had no UTF-8 stdio guard. Verified locally: `python -m ruff check scripts` (All checks passed); scripts/check_test_manifest.py; scripts/check_quality_metadata.py; scripts/check_architecture_contracts.py --base HEAD; scripts/check_nodiscard.py; `make -n check/examples`; scripts/check_examples.py (125 examples: 118 runnable, 7 reviewed non-runnable); and `python -X utf8 -m unittest discover -s scripts/tests -p "test_*.py"` (155 tests, OK). The runtime half of the contract needs a Linux headless build, so it is verified by the CI examples smoke step rather than locally.

"""Serve the EVEngine WebGPU build directory with cross-origin isolation.
|
|
|
|
The Emscripten build runs the engine on pthreads and needs SharedArrayBuffer,
|
|
so the page MUST be served with COOP/COEP headers -- opening eve.html via
|
|
file:// will not work. This server adds those headers plus no-store caching so
|
|
rebuilt eve.js / eve.wasm / eve.data are always picked up.
|
|
|
|
Usage (from the repo root):
|
|
python scripts/serve_webgpu.py # serves build/webgpu-web/src/engine :8090
|
|
python scripts/serve_webgpu.py <engine-dir> [port]
