Container changes: - Parameterize Dockerfile with ARG LANGUAGE (default rust); FROM now resolves to gcr.io/oss-fuzz-base/base-builder-${LANGUAGE} so the ClusterFuzzLite action's language: input drives the base layer. - Copy build_rust.sh, build_python.sh, and build_js.sh into the image and dispatch from build.sh via case on ${LANGUAGE:-rust}. Python harness (services 505, 509, 510; 506 deferred to WI-02): - build_python.sh installs per-service requirements.txt when present, builds each harness with PyInstaller --onefile, and emits an ASAN wrapper script that exports LD_PRELOAD for libasan before exec. JavaScript harness (service 513): - build_js.sh runs npm ci (falling back to npm install) before emitting the Jazzer.js wrapper so @jazzer.js/core resolves at fuzz time. - Add @jazzer.js/core ^2 as devDependency in 513 package.json. CI and docs: - Re-enable fuzz-python and fuzz-js jobs in fuzz-pr.yml (drop if: false). - Remove orphan fuzz-py-506 flag from codecov.yml. - Add .clusterfuzzlite/README.md describing the polyglot architecture. - Add docs/build-cicd/clusterfuzzlite.md with troubleshooting section. Decisions: - ID-02=A: bash-only build scripts (rejected pwsh shim to keep image size down and avoid pulling the PowerShell supply chain into a fuzzing base image). - ID-03=A: fold into existing PR #150 by stacking on the parent feat/issue-150-fuzzing-infrastructure branch rather than opening a new PR.

The +`build_fuzzers` action does not expose a `dockerfile-path` input, so +`edge-ai` uses a polyglot pattern: one Dockerfile parameterized by an +`ARG LANGUAGE` build-arg, paired with a top-level `build.sh` dispatcher that +hands off to a per-language `build_.sh` script. + +```text +language: (workflow job input) + | + v +ARG LANGUAGE (passed by the action as --build-arg) + | + v +FROM gcr.io/oss-fuzz-base/base-builder-${LANGUAGE} + | + v +build.sh --case--> build_rust.sh | build_python.sh | build_js.sh +``` + +Issue [#459](https://github.com/microsoft/edge-ai/issues/459) introduced the +polyglot pattern; the previous Rust-only scaffolding came from issue +[#150](https://github.com/microsoft/edge-ai/issues/150). + +## Language toolchains + +### Rust (cargo-fuzz, libFuzzer) + +Driven by `build_rust.sh`.

A short bash +wrapper sets the ASAN options expected by the fuzzing engine and execs the +PyInstaller binary. + +Atheris 3.0.0 pins Python 3.11; the CFLite base image upgrade tracked in +issue [#454](https://github.com/microsoft/edge-ai/issues/454) is gated on +either an Atheris 3.12 wheel or a replacement Python fuzzing engine. + +Harness `506-ros2` is excluded from the Python harness list because `rclpy` +(ROS 2 Python bindings) is not installable from PyPI; see issue +[#459](https://github.com/microsoft/edge-ai/issues/459) for the deferral +rationale. + +### JavaScript (Jazzer.js) + +Driven by `build_js.sh`.

In short: + +1. Drop the harness file under `tests/fuzz/` in the target service. +2. Append the harness entry to the matching `build_.sh` HARNESSES array. +3. Add a new `fuzz--` flag entry in + [`codecov.yml`](https://github.com/microsoft/edge-ai/blob/main/codecov.yml) + if the component number is new. + +## Troubleshooting + +### `bad_build_check` fails with `GLIBC_2.32 not found` + +The Dockerfile pinned a newer base-image tag (e.g. `:ubuntu-24-04`). The +CFLite runner is Ubuntu 20.04 / glibc 2.31. Remove the tag pin to fall back +to the default tag, which tracks the runner's glibc. + +### `pyinstaller: command not found` during a Python build + +`build_python.sh` installs PyInstaller on demand via `command -v pyinstaller`. +If the installation fails, `pip3 install --no-cache-dir pyinstaller` will +report the underlying error in the action log; usually a transient PyPI +outage. Re-run the workflow. + +### `Cannot find module '@jazzer.js/core'` during a JS build + +`@jazzer.js/core` is preinstalled globally in `base-builder-javascript`. If +the error appears at fuzz time (not build time), confirm the harness service +declares `@jazzer.js/core` in `devDependencies` and that `npm ci` ran +successfully (check the build log for an `EUSAGE` lockfile-mismatch error). + +### Workflow job stays skipped after enabling the gate + +`fuzz-python` and `fuzz-js` only run when the change-detection job emits a +non-empty `changedFuzzFolders` matrix.
