Summary by CodeRabbit

  • New Features
    • GPU probes now provide reference answers and recorded signatures across supported interfaces, including WebGPU and wasi:nn.
    • WASI boards provide wall-clock time as elapsed time.
  • Changed
    • ONNX Runtime loads on first wasi:nn use. Set ORT_DYLIB_PATH to choose its library; on Windows, the older System32 copy is no longer used.
  • Bug Fixes
    • GPU renderer reporting falls back to WebGL’s renderer string when the WebGPU adapter’s renderer is blank.

Walkthrough

The GPU probe crate adds host and combined-shader interfaces, registry lookup, and native and WASI-NN measurement tests. The WASI runner adds board clock functions. The pull request also updates ONNX Runtime loading configuration, optional-value handling, lint expectations, and advisory dates.

Changes: GPU probe signatures and measurements

Layer / File(s) Summary
Probe interfaces and answer generation
Cargo.toml, libs/gpu-probe/Cargo.toml, config/cargo-features.toml, libs/gpu-probe/src/lib.rs, libs/gpu-probe/tests/probe.rs
The crate adds combined-shader and host answers, interface labels, and additional legal probe answers. Tests cover shader output, host accuracy, and signature traits.
Signature registry and lookup
libs/gpu-probe/src/sighting.rs, libs/gpu-probe/src/registry.rs, libs/gpu-probe/signatures.yaml, .mise/config.toml, libs/gpu-probe/tests/sighting.rs, libs/gpu-probe/tests/probe.rs, config/*, .editorconfig, CHECKS.md
The crate parses typed sightings and matches signatures to registry entries. The YAML registry has recorded signatures and sightings. A generation task and check keep its JSON form synchronized. Supporting configuration updates handle generated files, duplication checks, and successful test output.
Native GPU and CPU measurements
libs/gpu-probe/tests/native.rs, config/nextest.toml
Native tests compile and dispatch probe shaders, collect answers, and check completion, repeatability, and matching sightings.
WASI-NN measurements and runtime loading
services/ws-wasi-runner/Cargo.toml, services/ws-wasi-runner/tests/nn_probe.rs, .mise/config.toml, .mise/config.windows.toml, services/ws-wasi-runner/Dockerfile, Cargo.toml, CHANGELOG.md
The runner test builds an ONNX probe model and checks its answers and repeatability. ONNX Runtime loading uses ORT_DYLIB_PATH on Unix and Windows, and the Docker image sets the library path.

WASI board clock and CLI functions

Layer / File(s) Summary
Hosted clock and CLI functions
libs/edge-toolkit/src/board.rs, services/ws-wasi-runner/src/board/wasi.rs, CHANGELOG.md
Boards host the wall-clock interface. The runner returns elapsed seconds and nanoseconds and adds exit-with-code.

Code and check maintenance

Layer / File(s) Summary
Optional-value defaults
libs/edge-toolkit/src/ws_server.rs, services/ws/src/admin.rs, utilities/cli/*, utilities/int-gen/*, utilities/repo-check/src/commit_hashes.rs
Optional-value lookups use map_or_default; the described fallback behavior remains unchanged.
Clippy lint expectations
services/recovery-supervisor/src/runtime.rs, services/websockify/src/lib.rs, services/ws-pyo3-runner/src/*, services/ws-wasi-runner/src/host/core_module.rs, services/ws/src/{backplane,connection}.rs
The code removes expectations for the integer division and remainder lint. Other listed lint expectations remain.
Repository configuration updates
config/deny.toml, config/osv-scanner.toml, config/conftest/policy/jscpd/jscpd.rego, config/jscpd-baseline.json, config/jscpd.json, config/generated-trees.toml, config/semgrep/prefer-yaml-toml.yaml, .mise/config.mingw.toml
The listed advisory entries use the expiry date 2027-01-01; config/deny.toml also adds advisory identifiers. The duplication ceiling and baseline change, generated signature files receive configuration exceptions, and the MinGW build-object path changes.

WASI board clock and CLI functions

Layer / File(s) Summary
Hosted clock and CLI functions
libs/edge-toolkit/src/board.rs, services/ws-wasi-runner/src/board/wasi.rs, CHANGELOG.md
Boards host the wall-clock interface. The runner returns elapsed seconds and nanoseconds and adds exit-with-code.

Explanation

The title "More GPU probe tests" matches a real part of the changeset. The PR adds native and nn_probe test suites, sighting tests, and probe test updates for GPU probes. It does not name the main change, which also includes the new signatures registry, host answers, and the ONNX Runtime loading change. The title is short and specific enough to pass, though it is somewhat narrow.

Check discrete answer validity on Windows.

On Windows, the registry assertion does not run. If the backend returns the same invalid bits twice for a probe with discrete legal choices, completed() still returns 16 and this test passes. Assert that signature.traits() contains no =other, as the native GPU tests do. This check does not replace a separate accuracy check for mathematical functions. (raw.githubusercontent.com)

Do not accept new clones in the jscpd baseline. Factor out the duplicated code.

This PR adds three fingerprints and removes one, so config/jscpd-baseline.json grows from 320 to 322 entries.
At least two of the added fingerprints do not replace a removed identity. They accept duplication that the base baseline did not accept.

The same PR raises declared_clones from 320 to 330 in config/conftest/policy/jscpd/jscpd.rego to allow this growth.
That file says raising the ceiling accepts duplication and needs the operator's explicit sign-off. The diff has no jscpd pin bump, and no sign-off is recorded in the reviewed context.
AGENTS.md also says the baseline is a debt ledger that must only shrink, except for a jscpd pin bump.

Factor the repeated code in the new libs/gpu-probe sources into a shared helper. Then remove the three added entries and lower declared_clones to the matching multiple of ceiling_step.
Lowering only the ceiling fails the policy, because 322 entries exceed 320.

Test both registry row error exits.

Both public callers supply entries from the embedded registry. The supplied entries have valid seen arrays and rows, so these calls exercise only successful parsing. Add module-local tests that pass malformed entries to rows and check propagation of both missing-seen and invalid-row errors.

As per coding guidelines, everything under libs/ requires coverage of "every line and every branch."

Return Unix epoch time from the wall-clock import.

The wasi:clocks wall-clock now import must return seconds since 1970-01-01T00:00:00Z. This code passes Platform::now() into the datetime result. Platform::now() returns nanoseconds since an unspecified fixed point, and the test platforms use zero or elapsed time as that point.

A guest that reads the wall clock receives board uptime as an epoch offset. For example, five seconds of uptime becomes 1970-01-01T00:00:05Z.

Provide a separate epoch-based time source for the wall-clock import. Do not reuse the monotonic Platform::now() value. Each Platform implementation in test_host.rs, board.rs, and board_net.rs must provide the new source or a compatible default.
